Description

Wireless access method, mobile terminal and server

Technical Field

The present invention relates to an access technology in the field of wireless communication, and in particular, to a wireless access method, a mobile terminal, and a server.

Background

With the popularization of wireless terminals, more and more users use wireless terminals for network access. The LTE network provided by the operator is one of the main radio access networks, and has a high speed and a wide coverage area, but is expensive. In order to make up for the shortcomings of the LTE network, WIFI networks have been developed. The WIFI network is low in price and convenient to deploy, and once the WIFI network appears, the WIFI network is rapidly popularized. At present, main office, business, entertainment and transportation places can see the figure of WIFI, and operators deploy free WIFI networks in a large range. WIFI networks have apparently become the preferred radio access network.

However, WIFI networks have their own drawbacks, and most notably their poor security. Anyone can simply deploy a WIFI network without the need for official authorization and provide it for his use at no cost, once the free WIFI network accessed by the user is insecure. In addition, the number of users accessing the WIFI network cannot be limited, and when the number of users accessing the WIFI network is large at the same time, the users cannot obtain enough bandwidth even if the signal intensity of the WIFI network is good, so that the network transmission speed is influenced, and poor user experience is brought.

A mobile terminal implementing various embodiments of the present invention will now be described with reference to the accompanying drawings. In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in themselves. Thus, "module" and "component" may be used in a mixture.

For example, the terminal described in the present invention may include a mobile terminal such as a mobile phone, a smart phone, a notebook computer, a digital broadcast receiver, a PDA (personal digital assistant), a PAD (tablet computer), a PMP (portable multimedia player), a navigation device, and the like, and a stationary terminal such as a digital TV, a desktop computer, and the like. In the following, it is assumed that the terminal is a mobile terminal. However, it will be understood by those skilled in the art that the configuration according to the embodiment of the present invention can be applied to a fixed type terminal in addition to elements particularly used for moving purposes.

More or fewer components may alternatively be implemented. Elements of the mobile terminal will be described in detail below.

The wireless communication unit 110 typically includes one or more components that allow radio communication between the mobile terminal 100 and a wireless communication system or network. For example, the wireless communication unit may include a mobile communication module 112, a wireless network communication module 113.

The broadcast associated information may also be provided via a mobile communication network, and in this case, the broadcast associated information may be received by the mobile communication module 112. The broadcast signal may exist in various forms, for example, it may exist in the form of an Electronic Program Guide (EPG) of Digital Multimedia Broadcasting (DMB), an Electronic Service Guide (ESG) of digital video broadcasting-handheld (DVB-H), and the like. The mobile communication module 112 transmits and/or receives radio signals to and/or from at least one of a base station (e.g., access point, node B, etc.), an external terminal, and a server. Such radio signals may include voice call signals, video call signals, or various types of data transmitted and/or received according to text and/or multimedia messages.

The wireless network communication module 113 supports wireless internet access of the mobile terminal. The module may be internally or externally coupled to the terminal. The wireless internet access technology to which the module relates may include WLAN (wireless LAN) (Wi-Fi), Wibro (wireless broadband), Wimax (worldwide interoperability for microwave access), HSDPA (high speed downlink packet access), and the like.

The user input unit 130 may generate key input data according to a command input by a user to control various operations of the mobile terminal. The user input unit 130 allows a user to input various types of information, and may include a keyboard, dome sheet, touch pad (e.g., a touch-sensitive member that detects changes in resistance, pressure, capacitance, and the like due to being touched), scroll wheel, joystick, and the like. In particular, when the touch pad is superimposed on the display unit 151 in the form of a layer, a touch screen may be formed.

The display unit 151 may display information processed in the mobile terminal 100. For example, when the mobile terminal 100 is in a phone call mode, the display unit 151 may display a User Interface (UI) or a Graphical User Interface (GUI) related to a call or other communication (e.g., text messaging, multimedia file downloading, etc.). When the mobile terminal 100 is in a video call mode or an image capturing mode, the display unit 151 may display a captured image and/or a received image, a UI or GUI showing a video or an image and related functions, and the like.

Some of these displays may be configured to be transparent to allow a user to view from the outside, which may be referred to as transparent displays, and a typical transparent display may be, for example, a TOLED (transparent organic light emitting diode) display or the like. Depending on the particular desired implementation, the mobile terminal 100 may include two or more display units (or other display devices), for example, the mobile terminal may include an external display unit (not shown) and an internal display unit (not shown). The touch screen may be used to detect a touch input pressure as well as a touch input position and a touch input area.

The memory 160 may store software programs and the like for processing and controlling operations performed by the controller 180, or may temporarily store data (e.g., a phonebook, messages, still images, videos, and the like) that has been or will be output. Also, the memory 160 may store data regarding various ways of vibration and audio signals output when a touch is applied to the touch screen.

The memory 160 may include at least one type of storage medium including a flash memory, a hard disk, a multimedia card, a card-type memory (e.g., SD or DX memory, etc.), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and the like. Also, the mobile terminal 100 may cooperate with a network storage device that performs a storage function of the memory 160 through a network connection.

The controller 180 generally controls the overall operation of the mobile terminal. For example, the controller 180 performs control and processing related to voice calls, data communications, video calls, and the like. In addition, the controller 180 may include a multimedia module 1810 for reproducing (or playing back) multimedia data, and the multimedia module 1810 may be constructed within the controller 180 or may be constructed separately from the controller 180. The controller 180 may perform a pattern recognition process to recognize a handwriting input or a picture drawing input performed on the touch screen as a character or an image.

The power supply unit 190 receives external power or internal power and provides appropriate power required to operate various elements and components under the control of the controller 180.

The various embodiments described herein may be implemented in a computer-readable medium using, for example, computer software, hardware, or any combination thereof.

For a software implementation, the implementation such as a process or a function may be implemented with a separate software module that allows performing at least one function or operation. The software codes may be implemented by software applications (or programs) written in any suitable programming language, which may be stored in the memory 160 and executed by the controller 180.

Up to this point, mobile terminals have been described in terms of their functionality. Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.

The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication systems such as wired and wireless communication systems and satellite-based communication systems that transmit data via frames or packets.

A communication system in which a mobile terminal according to the present invention is operable will now be described with reference to fig. 2.

Such communication systems may use different air interfaces and/or physical layers. For example, the air interface used by the communication system includes, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications System (UMTS) (in particular, Long Term Evolution (LTE)), global system for mobile communications (GSM), and the like. By way of non-limiting example, the following description relates to a CDMA communication system, but such teachings are equally applicable to other types of systems.

Referring to fig. 2, the CDMA wireless communication system may include a plurality of mobile terminals 100, a plurality of Base Stations (BSs) 270, Base Station Controllers (BSCs) 275, and a Mobile Switching Center (MSC) 280. The MSC280 is configured to interface with a Public Switched Telephone Network (PSTN) 290. The MSC280 is also configured to interface with a BSC275, which may be coupled to the base station 270 via a backhaul. The backhaul may be constructed according to any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, frame Relay, HDSL, ADSL, or xDSL. It will be understood that a system as shown in fig. 2 may include multiple BSCs 2750.

Each BS270 may serve one or more sectors (or regions), each sector covered by a multi-directional antenna or an antenna pointing in a particular direction being radially distant from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS270 may be configured to support multiple frequency allocations, with each frequency allocation having a particular frequency spectrum (e.g., 1.25MHz,5MHz, etc.).

The intersection of partitions with frequency allocations may be referred to as a CDMA channel. The BS270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to generically refer to a single BSC275 and at least one BS 270. The base stations may also be referred to as "cells". Alternatively, each sector of a particular BS270 may be referred to as a plurality of cell sites.

As shown in fig. 2, a Broadcast Transmitter (BT)295 transmits a broadcast signal to the mobile terminal 100 operating within the system. A broadcast receiving module 111 as shown in fig. 1 is provided at the mobile terminal 100 to receive a broadcast signal transmitted by the BT 295. In fig. 2, several Global Positioning System (GPS) satellites 300 are shown. The satellite 300 assists in locating at least one of the plurality of mobile terminals 100.

In fig. 2, a plurality of satellites 300 are depicted, but it is understood that useful positioning information may be obtained with any number of satellites. The GPS module 115 as shown in fig. 1 is generally configured to cooperate with satellites 300 to obtain desired positioning information. Other techniques that can track the location of the mobile terminal may be used instead of or in addition to GPS tracking techniques. In addition, at least one GPS satellite 300 may selectively or additionally process satellite DMB transmission.

As a typical operation of the wireless communication system, the BS270 receives reverse link signals from various mobile terminals 100. The mobile terminal 100 is generally engaged in conversations, messaging, and other types of communications. Each reverse link signal received by a particular base station 270 is processed within the particular BS 270. The obtained data is forwarded to the associated BSC 275. The BSC provides call resource allocation and mobility management functions including coordination of soft handoff procedures between BSs 270. The BSCs 275 also route the received data to the MSC280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN290 interfaces with the MSC280, the MSC interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS270 to transmit forward link signals to the mobile terminal 100.

Based on the above mobile terminal hardware structure and communication system, the present invention provides various embodiments of the method.

The first embodiment,

As shown in fig. 3, an embodiment of the present invention provides a wireless access method applied to a mobile terminal, including:

step 301: detecting at least one broadcast message sent by at least one wireless communication network;

step 302: acquiring network information of the at least one wireless communication network based on the at least one piece of broadcast information;

step 303: generating request information based on the network information of the at least one wireless communication network, and sending the request information to a server side through a mobile communication network, so that the server side screens the at least one wireless communication network based on the network information of the at least one wireless communication network in the request information, and sorts the transmission performance of the screened wireless communication networks;

step 304: receiving the sorted wireless communication network fed back by the server side through a mobile communication network;

step 305: and selecting a target wireless communication network based on the sorted wireless communication networks, and establishing connection with the selected target wireless communication network.

Here, the detecting to obtain at least one broadcast message sent by at least one wireless communication network may be: the user starts wireless communication network detection through the mobile terminal, and the mobile terminal starts to detect at least one piece of broadcast information sent by at least one wireless communication network at the periphery through a wireless communication function.

The wireless communication network may be a WIFI network.

The acquiring network information of the at least one wireless communication network based on the at least one broadcast information includes: and acquiring the service set identification, the physical address information and the signal strength of the at least one wireless communication network as network information based on the at least one piece of broadcast information. Wherein, the service set identifier may be an ssid (servicesetidentifier) of a wireless communication network; the physical address information may be a media access control (mac) (media access control) address of the wireless communication network.

Further, the generating of the request information based on the network information may be: acquiring the sequence of the detected network information of the at least one wireless communication network, and compressing the network information of the at least one wireless communication network based on the sequence; and generating the request information based on the compressed network information.

The selecting a target wireless communication network based on the sorted wireless communication networks, and establishing connection with the selected target wireless communication network may be:

selecting a first wireless communication network as a target wireless communication network, and establishing connection with the target wireless communication network;

or,

and according to the sequence of the wireless communication networks, sequentially trying to establish connection with the wireless communication networks until the connection with the target wireless communication network is successfully established. For example, if three sequenced wireless communication networks are fed back by the server side, the mobile terminal firstly selects a first wireless communication network as a target wireless communication network to be connected with the target wireless communication network; and if the connection fails, selecting a second wireless communication network as a target wireless communication network to be connected with the target wireless communication network, and if the connection succeeds, performing data interaction through the target wireless communication network.

The following describes an implementation scenario of the present embodiment with reference to fig. 4: in case a mobile terminal can be used, the user is necessarily in the coverage of the mobile base station. At some point, the user may want to use a wireless communication network, such as a WIFI network. Because the WIFI network can be set up at will, the user may be in the overlay network of a plurality of WIFI networks at the same time. As shown, when a user searches for WIFI in a mobile terminal, A, B, C, D, E may be simultaneously displayed and available, and at this time, when all WIFI are available for free, the user may preferentially select to use the signal strength best; when all WIFI signal strengths are consistent, the user chooses which network to use is completely random. Thus, the following two problems may occur: WIFI with better signal strength may be unsafe; the number of WIFI access persons with the best signal strength is large, and even if the WIFI access persons are accessed, the high transmission speed is difficult to obtain. As to how to select the target wireless communication network, the following describes a wireless access method at the mobile terminal side specifically, as shown in fig. 5, the whole process is as follows:

step 401, a user clicks a User Interface (UI) to prepare to connect to a WIFI network.

Step 402, the UI submits the user request to the WIFI retrieval module, so that the WIFI retrieval module starts the WIFI network card and detects broadcast information sent by the surrounding WIFI network.

And step 403, the WIFI network card submits the retrieved information to a WIFI information storage module, the information is stored mainly according to the sequence of the retrieved WIFI, and the SSID, the MAC address and the signal intensity corresponding to each WIFI are stored.

And step 404, compressing the stored information by the WIFI information storage module, generating request information, sending the request information to the base station, and waiting for a returned result.

Step 405, after receiving information returned by the base station (including a plurality of SSIDs and MAC addresses of available WIFI, and sorted in order according to a recommendation sequence) sent by the LTE network card, the WIFI information storage module sequentially finds out corresponding WIFI networks from the terminal storage information, and displays the available WIFI networks to the UI interface according to the recommendation sequence (for the user to freely switch, at this time, the unavailable or dangerous WIFI networks are shielded). Meanwhile, available WIFI network information is submitted to the WIFI retrieval module.

And 406, after receiving the information submitted by the WIFI information storage module, the WIFI retrieval module sequentially tries to connect the available WIFI networks according to the recommendation sequence. Once the connection is successful, the application layer is notified. Thus, the application layer APK data source can transmit data by using the WIFI network.

It should be noted that the main reasons why the terminal transmits the WIFI information by using the mobile communication network, such as the LTE network, are as follows: before finding a safe WIFI network, the WIFI network should not be connected to transmit data; the mobile communication network has higher speed, so that the terminal can be quickly exchanged with the server to obtain the retrieval result.

By adopting the scheme, the mobile terminal can detect the network information of at least one wireless communication network, send the request information to the server side of the mobile communication network based on the detected network information, screen and sort the wireless communication networks by the server side, and finally select the target wireless communication network for establishing the connection according to the screened and sorted wireless communication networks. Therefore, the purpose of making effective decision by using the network side is achieved, the mobile terminal can be accessed to the wireless communication network with safety and better transmission performance, and the user experience is favorably improved.

Example II,

An embodiment of the present invention provides a wireless access method, which is applied to a server, and as shown in fig. 6, the method includes:

step 601: receiving request information sent by a mobile terminal through a mobile communication network;

step 602: acquiring network information of at least one wireless communication network from the request information;

step 603: screening the at least one wireless communication network based on network information of the at least one wireless communication network;

step 604: sorting the transmission performance of the screened wireless communication networks based on the network information of the at least one wireless communication network;

step 605: and sending the sequenced wireless communication networks to the mobile terminal through the mobile communication network, so that the mobile terminal selects a target wireless communication network based on the sequenced wireless communication networks and establishes connection with the selected target wireless communication network.

Here, the mobile communication network may be embodied as a base station in a mobile communication network. Accordingly, the manner of receiving the request information of the mobile terminal from the mobile communication network may be that the base station receives the request information through at least one network device connected thereto.

The screening of the at least one wireless communication network may be security screening of the at least one wireless communication network based on the network information; for example, the authenticated wireless communication network may be determined based on network information of the at least one wireless communication network.

The server may preset and store information of the authenticated wireless communication network, for example, the information may include SSID and/or MAC address of the wireless communication network.

Further, based on the network information of the at least one wireless communication network, the transmission performance of the screened wireless communication networks is ranked, and the transmission performance of the screened wireless communication networks is evaluated based on the network information to obtain evaluation information for the transmission performance of each screened wireless communication network; determining the ranking of the wireless communication networks based on the screened evaluation information of the transmission performance of the wireless communication networks.

Example III,

It should be noted that the method further includes: acquiring geographical position information corresponding to the position of the mobile terminal sent by a mobile communication network; the manner for the mobile communication network to acquire the geographic location information corresponding to the location of the mobile terminal may be as follows: acquiring a cell corresponding to the position of the mobile terminal through a base station of a mobile communication network; and determining the geographical position information corresponding to the position of the mobile terminal based on the cell. Since the base station stores geographical location information corresponding to each cell in advance, the determination of the geographical location information can be determined based on the cell information.

Correspondingly, the acquiring network information of at least one wireless communication network from the request information includes:

and acquiring the service set identification, the physical address information and the signal strength corresponding to at least one wireless communication network from the request information. Wherein, the service set identifier may be an ssid (servicesetidentifier) of a wireless communication network; the physical address information may be a media access control (mac) (media access control) address of the wireless communication network.

Further, the screening the at least one wireless communication network based on the network information of the at least one wireless communication network includes:

determining a wireless communication network to be selected at the position of the mobile terminal based on the geographical position information corresponding to the position of the mobile terminal;

and screening to obtain the wireless communication network based on the wireless communication network to be selected and the medium service set identification and/or the physical address information in the network information of the at least one wireless communication network.

The method may further comprise: and pre-storing the service set identification and/or the physical address information of the at least one authenticated wireless communication network corresponding to each piece of geographical location information. The authenticated wireless communication network may be a wireless communication network subjected to security authentication, for example, the wireless communication network may be a wireless communication network subjected to authentication operation by a user or a merchant who sets the wireless communication network on a server side, where the authentication operation process may be an operation of uploading information such as a business license, and specific operations are not described herein.

Determining the wireless communication network to be selected at the position of the mobile terminal based on the geographical position information corresponding to the position of the mobile terminal, namely: and acquiring the authenticated wireless communication network and service set identification and/or physical address information thereof based on the geographic position information, and taking the acquired authenticated wireless communication network as a wireless communication network to be selected.

The screening of the wireless communication network based on the candidate wireless communication network and the mid-service set identifier and/or the physical address information in the network information of the at least one wireless communication network may be: and screening based on the service set identification and/or the physical address information in the information of the at least one wireless communication network and the service set identification and/or the physical address information of the wireless communication network to be selected to obtain the screened wireless communication network.

For example, as shown in fig. 7, it is assumed that the request message sent by the current mobile terminal includes a wireless communication network A, B, C, and the wireless communication network after the server detects the authentication of the location of the mobile terminal is A, C, D, E; the secure wireless communication networks obtained after screening by the server are A and C.

Correspondingly, the sorting the screened wireless communication networks includes:

acquiring the number of the access persons of the wireless communication network obtained by screening;

and sequencing the transmission performance of the wireless communication network based on the signal strength in the network information of the wireless communication network and the number of the access persons.

The number of the access persons of the wireless communication network obtained by the screening can be obtained by a server through data of background statistics; for example, the wireless communication network A, C screened in fig. 7; the number of the two access persons is respectively the wireless communication network A10 person and the wireless communication network C8 person.

Ranking the transmission performance of the wireless communication network based on the signal strength in the network information of the wireless communication network and the number of the access persons may comprise:

weighting the signal strength in the network information of the wireless communication network to obtain a weighted signal strength value;

dividing the weighted signal intensity value by the number of people accessing the wireless communication network to obtain the transmission performance of the wireless communication network;

the screened wireless communication networks are sorted in order from high to low based on the calculated transmission performance.

The weighted calculation of the signal strength may be to multiply the signal strength by a preset weighted value; the preset weighting value may be set according to an actual situation, for example, may be set to 1; or it may also increase the importance of the signal strength, i.e. set the weight to 1.5.

The scenario provided by the present embodiment is further described below with reference to fig. 8:

and after receiving the request message sent by the LTE base station, the server takes out the address information from the message. According to the address information, the data corresponding to the current request area is taken out from all the data, for example, all the data in the area A is taken out. The reason for this design is: each WIFI network covers a very limited range, so that the range covered by one base station can be divided into different "cells", just like a cellular network, and the WIFI networks exist in different "cells". Since one cloud server can store a large amount of information, the information-by-information comparison is time-consuming, and therefore the retrieval can be accelerated according to regions.

The request information sent by the LTE base station includes information of WIFI networks around the user, that is, the MAC address, SSID, and signal strength. And after the server takes the information out of the request, the security screening module is used for comparing the request information with the taken sample information to judge whether the WIFI network is secure. If the WIFI network is not safe, removing the WIFI network; and if the WIFI network is safe, the WIFI network is reserved. The key here is how to obtain valid sample information, and the strategy here may be similar to: after registration and authentication are carried out on a WIFI network provided by a large mall or a business with a regular business license, the server side marks the WIFI network as safe; for the WIFI network which is not authenticated, the WIFI network is not removed initially, but is arranged at a later position when reply information is generated, namely, the WIFI network is not recommended; if an unauthenticated WIFI network is reported, the server marks the WIFI network as unsafe; if an unauthenticated WIFI network is not reported for a long time and the number of users reaches a certain level, the server marks the WIFI as safe. The whole strategy is actually similar to a scoring mechanism of Taobao or popular comment, and when the use frequency of unknown WIFI is large (sales volume is large) and the WIFI is not reported (bad comment), the probability of the safety of the WIFI is high.

And after all the safe WIFI networks are filtered out, the server sorts all the available WIFI networks by using the priority sorting module. The general idea is as follows: priority is proportional to signal strength and inversely proportional to the number of people used. The signal intensity is obtained from request information sent by an LTE base station; and counting the number of the users of each WIFI network by the server. One of the strategies is: after each user sends the request information, the server selects the optimal wireless network for the user, and the user is considered to access the selected network. According to the assumption, the number of connected people of each WIFI network can be counted; another strategy is that the terminal initially collects the number of people connected to each surrounding WIFI network and transmits the information to the server. The strategy needs the support of a bottom layer protocol, the AP can actively send a broadcast frame to inform the terminal of the information, the terminal can also send a detection frame, and the number of people connected with the current WIFI network can be estimated according to the packet loss rate.

After finishing the sequencing of the available networks, the server compresses all the information and sends the information to the terminal for use.

The following describes the interaction process between the mobile terminal and the server with reference to the two embodiments:

when detecting the WIFI networks, the user collects information of each WIFI network, such as an SSID and a MAC address of an AP, and then the user can transmit all detected WIFI network information to the base station through the LTE network. Since only a small amount of information is needed to identify a specific WIFI network within an area, too much traffic is not consumed by the user.

After receiving the surrounding WIFI network information submitted by the user, the base station transmits the address information (the position of the user can be located by the base station) and the WIFI network information of the user to the remote server.

And after receiving the information, the far-end server calculates the WIFI network to which the user should access according to the geographic information, the WIFI security level, the WIFI signal strength and the number of the users accessing each WIFI network, and returns the calculation result to the base station.

And after receiving the calculation result of the server, the base station returns the calculation result to the user, so that the terminal automatically accesses to a proper WIFI network according to the calculation result. In fact, the terminal can display the filtered safe WIFI network on the UI interface, and the user can be given the right to select the WIFI network.
