Description

Method and equipment for realizing UE measurement

Technical Field

The present invention relates to the field of mobile communications, and in particular, to a method and apparatus for implementing User Equipment (UE) measurement.

Background

Three solutions for network selection are proposed in the current discussion of WLAN and 3GPP interworking (interworking), where the schemes 1 and 2 are operations for performing network selection and service migration by a UE, and the differences between the schemes 1 and 2 are that: in the scheme 1, the wireless access network only provides auxiliary information such as a threshold value and the like to assist the UE in network selection; in scheme 2, the radio access network may provide not only auxiliary information similar to that in scheme 1, but also policy information for network selection to assist the UE in network selection; the biggest difference between scheme 3 and schemes 1 and 2 is that the network selection in scheme 3 is controlled by the radio access network.

The core content of the above three schemes mainly includes network selection policies, including Inter-System Routing Policy (ISRP), Inter-System mobility Policy (ISMP), etc., but it does not mention what measurement Policy is used between systems. In fact, the measurement policy and measurement execution method both affect the user experience and the network performance, so the measurement is necessary to be handled as a basis for all mobility determination and execution. Currently, the measurement performed in the existing 3GPP protocol can be distinguished as the measurement when the UE is in a connected state and the measurement when the UE is in an idle state, where the difference in the measurements in the two states includes the difference in network elements using the measurement result, and the like. For a UE in the network environment of WLAN and 3GPP, it is required to ensure that it can perform measurement operation as required and to minimize power consumption of the UE, but no related art exists to provide the above-mentioned guarantee.

Detailed Description

In practical applications, the UE may obtain a 3GPP network and WLAN network interworking measurement criterion (hereinafter referred to as a 3-W measurement criterion), and perform measurement according to the measurement criterion. Wherein the obtained 3-W measurement criteria comprises at least one of:

UE triggers a WLAN measurement principle;

the UE stops the WLAN measurement principle.

When the UE obtains the 3-W measurement criterion, the method may be implemented by one of the following ways:

obtaining from the SIM card;

acquiring from a Radio Access Network (RAN);

the method includes obtaining from an Access Network Discovery and Selection Function (ANDSF) of a core Network element.

The UE triggers the WLAN measurement principle to:

the UE starts performing WLAN measurement after receiving the signaling indication from the network side.

after the UE is connected to the WLAN network, stopping WLAN measurement;

the UE stops WLAN measurements based on location information, such as the UE leaving the current 3GPP serving cell or leaving the coverage area of a WLAN Access Point (AP);

and when the measurement result of the UE serving cell is higher than the s-measure parameter configured by the network, stopping the WLAN measurement. The s-measure parameter is used to define whether the UE performs measurements.

The signaling indication of the network side may be sent to the UE by at least one of the following methods:

transmitting to the UE using Radio Resource Control (RRC) signaling; such as: can be to add information elements in the existing RRC signaling or define new RRC messages;

transmitting to the UE by using a Media Access Control (MAC) Control Element (CE);

and sending the message to the UE by using a system message.

To enable measurement of the UE, the network side may provide the UE with 3-W measurement criteria. Wherein the provided 3-W measurement criteria includes at least one of:

UE triggers a WLAN measurement principle;

UE stops WLAN measurement principle;

the network side may control the WLAN measurement of the UE in a signaling indication manner.

The present invention will be described in detail with reference to examples.

Example 1:

referring to fig. 1, in fig. 1, a network side sends a WLAN measurement start indication to a UE by using RRC signaling, and stops WLAN measurement after the UE connects to a WLAN network, and a process shown in fig. 1 includes the following steps:

step 101: the UE obtains a 3-w measurement strategy;

the acquisition of the 3-w measurement strategy may be achieved by one of the following: obtaining from the SIM card, or obtaining from the network side of RAN, or obtaining from the network element ANDSF of the core network by operating a pre-configuration mode of a background. In this example, the 3-W measurement policy is obtained from a core network element ANDSF.

Step 102: the UE executes measurement according to the obtained 3-W measurement strategy;

in this example, the 3-W measurement policy is obtained from a network element ANDSF of a core network, and the established UE triggers a WLAN measurement principle that the UE starts WLAN measurement only when receiving a signaling indication provided by a network side, and the principle that the UE stops WLAN measurement is that the UE stops WLAN measurement after successfully connecting to a WLAN network.

Step 103: UE initiates an RRC connection establishment flow due to service requirements;

in this example, the UE needs to transmit data and therefore needs to initiate an RRC connection establishment procedure, which is performed according to the existing protocol specifications.

Step 104: the network side informs the UE to start WLAN measurement by using RRC signaling;

for an LTE network, an indication signaling is sent by an eNB to a UE; for the UMTS network, indication signaling is sent by the RNC to the UE. In this example, the UE may be informed to start WLAN measurement using RRC Connection Reconfiguration (Connection Reconfiguration) signaling in RRC signaling.

Step 105: the UE starts to execute measurement after receiving the measurement instruction and judges whether the measurement result meets the service migration condition;

in this example, after receiving the WLAN measurement start indication message, the UE starts to perform WLAN measurement, and a measurement result obtained through the measurement satisfies a service migration condition.

Step 106: the UE connects with the WLAN network and starts service delivery;

in this example, the UE initiates a connection establishment procedure to the WLAN after the service migration condition is satisfied, performs WLAN network connection according to the existing protocol specification, and transfers data after successful connection.

Step 107: after the UE is successfully connected to the WLAN network, stopping measurement according to the 3-w strategy received from the ANDSF;

in this example, the WLAN measurement stopping principle configured by the ANDSF for the UE is to stop the WLAN measurement after the UE successfully connects to the WLAN network, and therefore stop the WLAN measurement after step 106 is successfully performed.

Example 2

Referring to fig. 2, in fig. 2, a network side sends a WLAN measurement start instruction to a UE by using RRC signaling, and sends a WLAN measurement stop instruction to the UE by using RRC signaling, and a process shown in fig. 2 includes the following steps:

step 201: the UE obtains a 3-w measurement strategy;

the acquisition of the 3-w measurement strategy may be achieved by one of the following: obtaining from the SIM card, or obtaining from the network side of RAN, or obtaining from the network element ANDSF of the core network by operating a pre-configuration mode of a background. In this example, the 3-W measurement policy is obtained from a 3GPP network element.

Step 202: the UE executes measurement according to the obtained 3-W measurement strategy;

in this example, the 3-W measurement policy is obtained from the 3GPP network element, and the formulated UE triggers the WLAN measurement principle that the UE starts WLAN measurement only when receiving a signaling indication provided by the network side, and the principle that the UE stops WLAN measurement is that the UE sends a WLAN measurement stop indication to the UE by using RRC signaling.

Step 203: UE initiates an RRC connection establishment flow due to service requirements;

Step 204: the network side informs the UE to start WLAN measurement by using RRC signaling;

for an LTE network, an indication signaling is sent by an eNB to a UE; for the UMTS network, indication signaling is sent by the RNC to the UE. In this example, the UE may be informed to start WLAN measurement using RRC ConnectionReconfiguration signaling in RRC signaling.

Step 205: the UE starts to execute measurement after receiving the measurement instruction and judges whether the measurement result of the measurement is the report condition of the measurement report;

in this example, after receiving the WLAN measurement start indication message, the UE starts to perform WLAN measurement, and the measurement result obtained through measurement satisfies the measurement report condition, and the UE needs to send a measurement report to the network side.

Step 206: UE sends a measurement report to a network side;

in this example, the reason why the UE sends the measurement report to the network side is that the network needs to decide whether to perform the service migration operation according to the measurement report.

Step 207: the network side judges whether to execute the service migration operation by using the measurement report sent by the UE, and if so, sends a steering command (steering command) message to the UE.

In this example, the network side determines that the UE satisfies the condition for executing service migration according to the obtained measurement report, and sends a steering command message to the UE. According to the 3-w measurement criterion configured by the network side, the network side instructs the UE to stop the WLAN measurement in a steering command message.

Step 208: the UE stops the WLAN measurement, connects to the WLAN network and starts service delivery;

in this example, the UE migrates the service to the WLAN network according to the steering command sent by the network side, performs WLAN network connection according to the existing protocol specification, and transfers data after successful connection. And simultaneously, the UE stops the WLAN measurement according to the received indication signaling.

Step 209: the UE sends a stepping command ACK message to the network side;

in this example, the UE sends a steering command ACK message to the network side to inform the network side of the completion of the service migration.

Example 3

Referring to fig. 3, in fig. 3, a network side sends a WLAN measurement start indication to a UE by using a system message, and the UE stops WLAN measurement when leaving a current serving cell, where the process shown in fig. 3 includes the following steps:

step 301: the UE obtains a 3-w measurement strategy;

Step 302: the UE executes measurement according to the obtained 3-W measurement strategy;

in this example, the 3-W measurement policy is obtained from the 3GPP network element, and the formulated UE triggers the WLAN measurement principle to start WLAN measurement only when the UE receives a signaling indication provided by the network side, and the UE stops the WLAN measurement principle to stop WLAN measurement when the UE leaves the serving cell.

Step 303: the network side informs the UE to start WLAN measurement by using broadcast signaling;

step 304: the measurement result obtained by the UE meets the triggering condition of the mobility event;

step 305: the UE sends a measurement report to the network, wherein the measurement report is relevant to the switching;

in this example, the UE sends a measurement report related to mobility to the network side according to the obtained measurement result, so as to assist the network side in making a handover decision.

Step 306: the network side determines to execute the switching operation after receiving the measurement report of the UE;

in this example, the source eNB sends a handover command (HO command) message to the UE.

Step 307: and after receiving the HO command message, the UE stops executing the WLAN measurement.

In this example, the principle that the network side sets up the 3-W measurement criterion for the UE indicates that the UE stops WLAN measurement is that the WLAN measurement stops when the UE leaves the serving cell, and therefore the UE stops WLAN measurement after receiving the HO command.

Example 4

Referring to fig. 4, in fig. 4, a network side sends a WLAN measurement start instruction to a UE by using MAC CE signaling, and stops WLAN measurement when a measurement result of a serving cell of the UE is higher than an s-measure parameter configured by a network, where the flow shown in fig. 4 includes the following steps:

step 401: the UE obtains a 3-w measurement strategy;

Step 402: the UE executes measurement according to the obtained 3-W measurement strategy;

Step 403: UE initiates an RRC connection establishment flow due to service requirements;

Step 404: the network side configures s-measure parameters for the UE by using RRC signaling;

in this example, the network side configures an s-measure parameter for the UE, and the parameter value is-100 dBm.

Step 405: the network side informs the UE to start WLAN measurement by using the MAC CE;

the network side informs the UE to turn on WLAN measurement using MAC CE (e.g. sequence number in MAC CE), see table 1:

serial number	Logical Channel (LC) ID value
		00000	Common control channel
00001-01010	Logical channel ID

01011-11010	Reserved serial number
		11011	Activation/deactivation
11100	UE contention resolution identity
		11101	Timing advance command
11110	DRX commands
		11111	Filling in

TABLE 1

As can be seen from table 1, 1 LC ID is scribed in the reserved sequence number, which LC ID is 01100, for defining the WLAN measurements to be turned on. After reading the LC ID, the UE knows to start WLAN measurement according to a 3-w measurement rule.

Step 406: the UE judges whether Reference Signal Received Power (RSRP) of the main cell is higher than an S-measure parameter so as to judge whether to stop WLAN measurement;

in this example, the measurement result obtained by the UE indicates that the reference signal received power of the primary cell is greater than the s-measure parameter, and therefore the WLAN measurement is stopped.

It should be noted that the UE may include a collection unit and a measurement unit; wherein the collecting unit is configured to obtain the measurement criterion; the measurement unit is used for executing measurement according to the measurement criterion. Specifically, the collection unit may be an information processor or a wireless reception module in the UE.

In combination with the above description, it can be seen that, in the method and the device, the technology for implementing UE measurement in the present invention reduces the power consumption of the UE while ensuring the measurement requirement of the UE through the formulation of the measurement rule, so that the user equipment has better performance experience no matter in WLAN or 3 GPP.

It will be apparent to those skilled in the art that the modules or steps of the present invention described above may be implemented by a general purpose computing device, they may be centralized on a single computing device or distributed across a network of multiple computing devices, and alternatively, they may be implemented by program code executable by a computing device, such that they may be stored in a storage device and executed by a computing device, and in some cases, the steps shown or described may be performed in an order different than that described herein, or they may be separately fabricated into individual integrated circuit modules, or multiple ones of them may be fabricated into a single integrated circuit module. Thus, the present invention is not limited to any specific combination of hardware and software.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
