Description

 Method and system for listening to paging

Technical field

 The present invention belongs to the field of communication technologies, and in particular, to a method and system for intercepting paging.

Background technique

 WiMAX is called World Interoperability for Microwave Access, which is a global wireless access network. It is a broadband wireless access metropolitan area network technology based on the IEEE 802.16 standard. It is used in the metro access environment to ensure that wireless devices from different vendors interact with each other. Interconnected, mainly used to provide "last mile" high-speed broadband access for homes, businesses and mobile communication networks, as well as future personal mobile communication services.

 Regarding the IEEE 802.16 standard, the industry's most concerned is IEEE 802.16e. The biggest difference between it and the previous 802.16 standards is its support for mobility. The purpose of the 802.16e standard is to propose a broadband wireless access solution that provides both high-speed data services and user mobility. Based on the fixed air interface 802.16d technology, it adds some important features such as handover support, terminal (Mobile Staiton, MS) sleep mode, paging and enhanced security capabilities, making MS roaming and handover possible. .

 The MS sleep modes in the 802.16e protocol include: Sleep mode and Idle mode. The purpose of the Sleep mode is to reduce the energy consumption of the MS and reduce the use of air resources for the serving base station (Base Station, hereinafter referred to as BS). The Idle mode provides a more power-saving mode for the MS than the Sleep mode. After entering the Idle mode, the MS periodically receives downlink broadcast data (including paging messages and multicast broadcast services) at discrete intervals. (Multicast & Broadcast Service, hereinafter referred to as MBS)), and during the movement through multiple BSs, the process of handover and network re-entry is not required.

In the prior art, when the upper layer entity of the network detects that the MS in the Idle mode has a message, the process of paging the MS is initiated. The process of paging the MS is as follows: The paging controller (Paging Controller, PC, can be integrated in the base station BS when implemented, and can be integrated in the gateway (Gateway, In the following GW), it can also be integrated in other network entities, or as a separate network entity) to notify the paging agent (Paging Agent, PA) in the entire paging group (Paging Grou, hereinafter referred to as PG). It can be integrated in the BS. It needs to initiate a paging message and bring the MS identity that needs to be paged. Then the PA generates a paging message with a certain MS identity and sends it on the air interface. When the MS receives the MS identity matching the self in the paging message, it knows that the PA is paging it, and then the MS performs the network access. process. The BS is usually available as a PA in IEEE 802.16e. A paging group is to put one or more PAs in a group. When the MS moves to cross the paging group, the MS needs to register its own location. Thus, when the PC needs to page the MS, the MS can be paged in a paging group. The above paging is usually implemented by the BS broadcast MOB_PAG-ADV message. When the MS receives the MOB_PAG-ADV message, the hash value of the MS Media Access Control (MS MAC) address is parsed therefrom. Matching with its own hash value means that the BS is paging itself, and then the MS performs the corresponding action according to the Action Code in the MOB_PAG-ADV.

 When the MS enters the idle mode (Idle Mode), it periodically wakes up during the paging interval, that is, from the paging unavailable interval (Paging unavailable interval) to the paging listening interval (Paging Listening Interval), and enters the paging detection. The terminal can receive the MOB-PAG-ADV message after listening to the interval.

 All of the above describes the paging procedure for the common terminal. However, as the bandwidth resources available to the current communication system become larger and larger, the requirements for the terminal are also higher and higher, and thus a terminal supporting multiple carriers appears. A multi-carrier-capable terminal has the ability to simultaneously demodulate on multiple carriers of the system. The system can schedule resources on multiple carriers at the same time, thereby providing a high peak rate and meeting some peak rate requirements. Business requirements. However, the inventors of the present application have found that the current related standards do not describe much how to support multi-carrier terminals for paging, but emphasize that when a terminal has the ability to demodulate multiple carriers, it will demodulate multiple carriers simultaneously. Therefore, for a terminal supporting multiple carriers, how to listen to paging messages, there is no related solution in the prior art. Summary of the invention

Embodiments of the present invention provide a method and system for listening to paging, by which the system and system The problem of how a terminal supporting multiple carriers can listen to a paging message can be solved.

 A method for listening to paging provided by an embodiment of the present invention includes the following steps:

 The terminal receives the message from the base station, where the message includes the priority paging carrier information; the terminal listens to the paging message by using the priority paging carrier corresponding to the priority paging carrier information. A system for listening to paging provided by the present invention includes:

 a base station, configured to send a broadcast message, where the broadcast message includes priority paging carrier information, and a terminal, configured to receive a broadcast message from the base station, and use the priority paging carrier corresponding to the priority paging carrier information in the broadcast message Listen to the paging message.

 The present invention further provides two types of terminals, which can be used for listening to paging messages, wherein a terminal includes: a first receiving module, configured to receive a message from a base station, where the message includes priority paging carrier information;

 And a second receiving module, configured to listen to the paging message by using the priority paging carrier corresponding to the priority paging carrier information.

 Another type of terminal includes:

 a negotiation module, configured to negotiate with the base station to determine priority paging carrier information;

 a negotiation module, configured to negotiate with the terminal to determine priority paging carrier information;

 The first sending module is configured to send a paging message to the terminal by using the priority paging carrier corresponding to the priority paging carrier information.

It can be seen from the above technical solution that the embodiment of the present invention can determine one carrier (ie, preferential paging carrier) by interacting with the terminal and the base station. If the terminal can support multiple carriers, when the terminal enters the idle mode, the terminal only This priority paging carrier needs to be listened to to obtain a paging message. Through this scheme, the problem of how a terminal supporting multiple carriers listens for paging messages is solved. And in this solution, the terminal does not need to listen to all carriers that it can support, thereby greatly saving the power of the terminal. DRAWINGS

detailed description

 The embodiment of the invention provides a scheme for listening to paging. In this scheme, even if the terminal can support multiple carriers, when the terminal enters the idle mode, it only listens to the paging message on a pre-agreed carrier, and this carrier can be called the priority paging of the terminal. Carrier. Through this scheme, the problem of how to listen to paging messages for terminals supporting multiple carriers is solved. And in this scheme, since the terminal does not need to listen to a plurality of carriers that it can support, the power of the terminal is greatly saved.

The above-mentioned priority paging carriers may be terminal-based, that is, the priority paging carriers corresponding to each terminal are relatively independent; or may be base station-based, that is, the priority paging carriers corresponding to each base station are relatively independent; It can be group-based, that is, multiple terminals or base stations belong to the same group. The priority paging carriers corresponding to each group are relatively independent, and in the case of group based, it is preferably based on paging groups.

 The solution described in the embodiment of the present invention will be described below with reference to the accompanying drawings.

 Referring to the flow shown in FIG. 1, the first embodiment of the present invention provides a method for listening for paging, and the method includes the following steps:

 Step 101: The terminal receives a message from the base station, where the message includes priority paging carrier information. Step 102: The terminal listens to the paging message by using the priority paging carrier corresponding to the priority paging carrier information.

 In the method according to the first embodiment of the present invention, the terminal only needs to listen to one carrier (for example, preferentially searching for a carrier), and can know whether there is a paging message for it. With this method, the terminal does not need to listen to all the carriers that can be supported, thereby greatly saving the power of the terminal.

 In order to make the technical solutions of the present invention clearer, the technical solutions of the present invention will be described below by way of more specific embodiments.

 The priority paging carriers may be group-based, and each group may include multiple base stations or terminals, and the priority paging carriers corresponding to each group are relatively independent. In the case where the priority paging carrier is a group-based, it is preferable to use a paging group. Referring to the signal flow chart of FIG. 2, the second embodiment of the present invention uses a paging group as an example, and the method includes the following steps:

 The terminal performs the synchronization operation of the network. Since the network synchronization operation is prior art, it will not be described here.

 Step 201: After completing the network synchronization operation, the terminal receives the broadcast message from the base station, where the broadcast message includes the paging group identifier of the paging group and the priority paging carrier information corresponding to the paging group, and preferentially paging the carrier information. The carrier index or the center frequency point or bandwidth corresponding to the priority paging carrier may be included.

The paging group described in step 201 may be a paging group corresponding to the base station or a paging group corresponding to the terminal. The paging group corresponding to the base station may be multiple, so the paging group identifier corresponding to the base station may also be multiple. The paging group identifiers are usually stored in a list (such as a Group List), and the base station may This list is sent to the terminal by broadcast message.

 Step 202: The terminal saves the paging group identifier of the paging group in the broadcast message and the priority paging carrier information corresponding to the paging group.

 It should be noted that step 202 is optional. That is, the terminal may not save the paging group identifier of the paging group in the broadcast message and the priority paging carrier information corresponding to the paging group after receiving the broadcast message from the base station.

 Step 203: The terminal acquires a corresponding priority paging carrier according to the paging group to which the terminal belongs, and after entering the idle mode, intercepts the paging message by using the priority paging carrier.

 In the process described in the foregoing Embodiment 2, after the step 202 is performed, in some scenarios, the terminal may enter the idle mode (Idle Mode), and the terminal that enters the idle mode periodically wakes up, that is, from the paging. The Paging unavailable interval is transferred to the Paging Listening Interval. When the terminal enters the paging listening interval, the terminal attempts to synchronize on the priority paging carrier first. If the synchronization succeeds, the synchronization is completed. The broadcast message is then listened to on the priority paging carrier. As shown in Figure 3, assuming that the priority paging carrier corresponding to the saved priority paging carrier information in the terminal is RF1, the terminal performs the following steps after waking up:

 Step 301: The terminal attempts to synchronize on the priority paging carrier RF1. If the terminal successfully synchronizes with the RF1, step 302 is performed. If the terminal fails to synchronize with the RF1, step 305 is performed.

 Step 302: The terminal listens to the broadcast message sent by the base station on the carrier RF1, and determines whether the paging group identifier or the priority paging carrier information changes according to the broadcast message. If no change occurs, step 303 is performed; if the change occurs, the step is performed. 304.

 For determining whether the paging group identifier or the preferential paging carrier information in the broadcast message changes, the paging group identifier or the preferential paging carrier information in the broadcast message may be identified or preferentially searched by the paging group saved in the terminal. The carrier information is compared to achieve, if there is no change, there is no change; if it is inconsistent, it changes.

Step 303: The terminal continues to listen to the broadcast message on the carrier on the carrier RF1 to receive the paging message. If the terminal listens to the broadcast message on the carrier RF1, if there is a paging message for the terminal, the terminal will perform a corresponding action according to the content of the paging message, such as re-entering the network, or continuing in the idle mode and the like. If the terminal has not received a paging message for it in the Paging Listening Interval, the terminal will re-turn to the Paging unavailable interval.

 Step 304: The terminal synchronizes with the priority paging carrier corresponding to the latest priority paging carrier information. After the synchronization succeeds, the terminal listens to the broadcast message on the current priority paging carrier to receive the paging message.

 If the paging message identifier (Paging Group ID) or the corresponding priority paging carrier (Primary Paging Carrier) information in the broadcast message in step 302 is inconsistent with the local storage of the terminal, the terminal has reached the range of another paging group. At this time, the terminal will update the locally saved information according to the priority paging carrier information in the broadcast message that is heard, and re-synchronize on the carrier according to the latest priority paging carrier information, and listen to the carrier after the synchronization is completed. Broadcast message.

 Step 305: The terminal synchronizes with other carriers that can be supported. If the synchronization succeeds on any of the supported carriers, step 306 is performed.

 Step 306: The terminal receives the broadcast message on the successfully synchronized carrier, and obtains the priority paging carrier information according to the received broadcast message. If the priority paging carrier corresponding to the priority paging carrier information is not the successfully synchronized carrier, step 307 is performed. If the priority paging carrier corresponding to the priority paging carrier information is the carrier that is successfully synchronized in step 305, step 308 is performed.

 Step 307: The terminal attempts to synchronize with the priority paging carrier corresponding to the priority paging carrier information. After the synchronization succeeds, step 308 is performed.

 Step 308: The terminal listens to the broadcast message on the priority paging carrier until its paging listening interval ends.

In the above step 308, if the terminal does not have a paging message for it during the listening of the broadcast message on the current priority paging carrier, it will re-turn to the paging invalidation interval; if there is a paging message for it, the terminal will The corresponding action is performed according to the content of the paging message, such as re-entering the network, or continuing to be in the idle mode, and the like. In the method described in the foregoing Embodiment 2, the priority paging carrier is based on the paging group or the base station. In the method described in the embodiment of the present invention, the priority paging carrier may also be based on the terminal, that is, the priority corresponding to each terminal. The paging carrier can be independent. After the terminal is initially connected to the network, the device may first negotiate with the base station to preferentially page the carrier information, for example, through media access control (MAC) layer message negotiation. After the terminal enters the idle mode, the terminal only listens for paging messages on its corresponding priority paging carrier.

 The negotiation process may be initiated by the terminal, or may be initiated by the base station. As shown in FIG. 4, the method for negotiating the priority paging carrier between the base station and the base station initiated by the terminal in the third embodiment of the present invention mainly includes the following steps:

 Step 401: The terminal sends a priority paging carrier information negotiation request message to the base station, where the message may carry one or more recommended priority paging carrier information.

 Each of the priority paging carrier information described above may include information such as a carrier index or a center frequency or a bandwidth.

 Step 402: The base station sends a priority paging carrier information negotiation response message to the terminal, where the message carries the priority paging carrier information allowed by the base station.

 In general, the terminal has only one priority paging carrier. Therefore, the priority paging carrier information of the terminal allowed by the base station usually only corresponds to one priority paging carrier. However, in implementation, the terminal may also have multiple priority paging carriers, and the priority paging carrier may be a subset of carriers supported by the terminal, that is, the priority paging carrier of the terminal is one or more of the carriers that the terminal can support. .

 After the terminal enters the idle mode, the terminal may listen to the paging message by using the priority paging carrier corresponding to the priority paging carrier information allowed by the base station.

 The process of the negotiation may be initiated by the base station. As shown in FIG. 5, the method for negotiating the preferential paging carrier between the terminal and the terminal initiated by the base station in the fourth embodiment of the present invention mainly includes the following steps:

 Step 501: The base station sends a priority paging carrier information negotiation request message to the terminal, where the message may carry one or more recommended priority paging carrier information.

Each of the above priority paging carrier information may include a carrier index or a center frequency point or Information such as bandwidth.

 Step 502: The terminal sends a priority paging carrier information negotiation response message to the base station, where the message carries the priority paging carrier information supported by the terminal.

 In general, there is usually only one priority paging carrier information supported by the terminal. However, in implementation, the terminal may also have multiple priority paging carriers, and the priority paging carrier may be a subset of carriers supported by the terminal, that is, the priority paging carrier of the terminal is one or more of the carriers that the terminal can support. .

 In step 502, the terminal may determine the priority paging carrier in a plurality of manners, and then send the priority paging carrier to the base station by using a negotiation response message. The method for determining the priority paging carrier is not limited. For example, the terminal may determine the priority paging carrier according to the result of the scanning, or may determine the priority paging carrier by using a predetermined algorithm. In addition, there are of course many other methods. , can't be here - enumeration.

 After the terminal enters the idle mode, the terminal may listen to the paging message by using the priority paging carrier corresponding to the priority paging carrier information supported by the terminal.

 In practical applications, the priority paging carrier negotiation process can be implemented by entering a message flow in an idle state, for example, by adding a priority paging carrier information in a DREG-REQ/DREG-CMD message. Of course, it can also be implemented by other message interaction processes, as long as these messages are added to carry priority paging carrier information, such as terminal and base station capability negotiation process (SBC-REQ/SBC-RSP), ranging process (RNG-REQ/ RNG-RSP), registration process (REG-RNG/REG-RSP), location update process (Location Update REQ/Location Update RSP), etc.

 After the terminal negotiates the priority paging carrier with the base station by using the method described in the third embodiment and the fourth embodiment, if the terminal enters the idle mode, the terminal can listen to the paging message on the priority paging carrier.

It should be noted that when the terminal enters the idle mode or enters the idle mode, some of its information needs to be saved in the paging controller (PC, Paging Controller. In implementation, the PC can be integrated in the base station BS and can be integrated in the access. In the gateway GW, it may also be integrated in other network entities, or as a separate network entity, such as information such as priority carrier information, which may be The base station can be used to page the terminal after the terminal enters the idle mode. The information may be saved by the terminal to the PC during the negotiation process. For example, if the PC is not integrated in the base station, the base station may pass a message after receiving the priority paging carrier information negotiation request message from the terminal in step 401. Sending the information to the PC, informing the PC to save the information; or after receiving the priority paging carrier information negotiation response message sent by the terminal, the base station sends the information to the PC through a message, and notifies the PC to save the information; The PC is integrated in the base station, and this information can be saved to the PC through some information interaction inside the base station. In addition, the information may also be stored in the PC when the terminal interacts with the base station during the process of entering the IDLE.

 When the terminal enters the idle mode, if the upper layer entity of the network detects that the terminal in the idle mode has a message or the data arrives, the process of paging the terminal is initiated. For the detailed procedure of the paging, refer to the schematic diagram of the paging process shown in FIG. 6 of the present invention, which specifically includes the following steps:

 Step 601: The network side triggers the paging terminal. At this time, the paging controller sends a paging message to the paging proxy, where the paging message carries the MAC address identifier and the preferential paging carrier information of the terminal to be paged.

 The network side in step 601 may be a base station, but is not limited to a base station.

 Step 602: The paging proxy PA (which may be integrated in the base station when implemented, may also be integrated in other network entities, or as a separate network entity), after receiving the paging message sent by the paging controller, only A paging message is sent on the priority paging carrier corresponding to the terminal, and the paging message includes a MAC address identifier of the terminal to be paged or a hash value of the MAC address identifier.

 In step 602, it should be noted that if the PA does not support the priority paging carrier corresponding to the terminal, it will send a paging message on all carriers it supports.

 Step 603: The terminal detects a paging message on the priority paging carrier. When the paging message has its MAC address or a hash value of the MAC address, it knows that the paging proxy PA is paging it, and the terminal according to the paging. The message content indicates that the corresponding action is performed, such as re-entering the network, or continuing to be in idle mode, and the like.

In addition to the foregoing method for listening to paging, an embodiment of the present invention further provides a terminal, which may be a terminal supporting multiple carriers, and the terminal may interact with a base station to determine a carrier (ie, Priority paging carrier), after the terminal enters the idle mode, the terminal only needs to listen to the priority paging carrier to obtain the paging message. Through this scheme, the problem of how the terminal supporting the multi-carrier listens for the paging message is realized. And because the terminal does not need to listen to all the carriers it can support, the power of the terminal is greatly saved.
