Abstract

Disclosed in the present invention are a method and device for controlling an RRC connection state between UE and a network side. When a connection relationship between the UE and the network side exists, if the UE determines, according to an operation parameter of the UE, that a data service needed to be executed does not exist in a time length corresponding to a duration information of a CDRX mode distributed by the network side, the UE disconnects the RRC connection between the UE and the network side. With the technical solution of the present invention, when the time of the data service needed to be executed does not exist in the duration of the CDRX mode distributed by the network side, the UE only needs simple signaling interaction with the network side, i.e., the UE may be switched from CDRX mode to a DRX mode. Since neither PDCCH monitoring nor the signaling interaction with the network side is needed when the UE is in the DRX mode, the power assumption of the UE is reduced effectively, and the signaling interaction between the UE and the network side is decreased, and the network performance is improved.

Description

Method and device for controlling RRC connection state between UE and network side

This application claims priority to Chinese Patent Application No. 201310430198.2, entitled "Method and Apparatus for Controlling RRC Connection Status Between UE and Network Side", filed on September 18, 2013, The content is included in this application by reference.

Technical field

The present invention relates to the field of communications, and in particular, to a method and apparatus for controlling an RRC connection state between a UE and a network side.

Background

In the LTE (Long Term Evolution) system, when the UE (User Equipment) and the network side perform service data exchange, that is, when the UE performs data services, the RRC needs to be established between the UE and the network side. (Radio Resource Control) connection. After the data service ends, the network side sends a CDRX (Connected State DRX) mode duration information to the UE. When the CDRX mode duration expires, the UE updates its own RRC connection state with the network side. As shown in FIG. 1 , the foregoing process is specifically: Step 100: The network side sends CDRX mode duration information to the UE. Step 110: The UE receives the CDRX mode duration information, and determines that the time corresponding to the CDRX mode duration information arrives, and sends an RRC disconnect request to the network side. When the duration of the CDRX mode is not reached, the UE is in the CDRX mode, and the UE reports the network performance parameters, such as the UE moving speed, and the CQI (Channel Quality Indicator) parameters, to the network side according to the preset period. . Step 120: The network side feeds back the permission disconnection instruction to the UE according to the RRC disconnection request. Step 130: The UE receives the above-mentioned permission disconnection instruction, disconnects the RRC connection with the network side according to the allowable disconnection command, and causes the UE to switch to the DRX (Discontinuous Reception) mode. It can be seen from the above process that the RRC connection relationship between the UE and the network side is in a hold state within a time length corresponding to the CDRX mode duration information. In the DRX mode, the UE disconnects from the network side.

Control channel) listening. Therefore, the network side sends a fixed CDRX mode duration information. After the CDRX mode duration expires, the UE can disconnect the RRC connection with the network side, that is, when the CDRX mode duration does not arrive, the UE needs to The network side maintains the RRC connection, and reports the network performance parameter to the network side according to the preset period, thereby increasing the power consumption of the UE and reducing the network performance.

In the embodiment of the present invention, when there is an RRC connection relationship between the UE and the network side, the UE is in accordance with the UE. The RRC connection between the UE and the network side is disconnected when there is no data service to be performed within the length of time corresponding to the CDRX mode duration information delivered by the network side. With the technical solution of the present invention, when there is no data service to be performed within the time length corresponding to the CDRX mode duration information delivered by the network side, only a simple signaling interaction between the UE and the network side is required, and the CDRX mode can be adopted. Switching to the DRX mode, since the UE does not need to perform PDCCH monitoring when the UE is in the DRX mode, and does not need to perform signaling interaction with the network side, thereby effectively reducing the power consumption of the UE and reducing the signaling interaction between the UE and the network side. Improve network performance.

FIG. 2 is a schematic diagram of a system architecture in an embodiment of the present invention, where signaling interaction between a UE and a network side is performed. FIG. 3 is a waveform diagram of power consumption corresponding to the CDRX mode and the DRX mode in the UE according to the embodiment of the present invention; when the UE has a data service to be executed, the UE is awakened, and the data service to be executed ends. After that, the UE enters the CDRX mode, and when the CDRX mode duration arrives, the UE switches to the DRX mode.

Referring to FIG. 4, in the embodiment of the present invention, the detailed process for reducing UE power consumption is:

Step 400: After the UE and the network side are in an RRC connection state, and the currently executed data service between the UE and the network side ends, the CDRX mode duration information sent by the network side is obtained.

In the embodiment of the present invention, when there is a data service to be performed between the UE and the network, and the RRC connection is not established between the UE and the network, the UE sends an RRC connection setup request to the network side, and the network side is based on the RRC connection. The establishment request feeds back the permission connection establishment response message to the UE, and after the UE acquires the permission connection establishment response message, the RRC connection with the network side is established. At this time, the UE can perform the foregoing data service. After the data service ends, the UE obtains the CDRX mode duration information, where the CDRX mode duration information is sent by the network side, and the duration of the CDRX mode duration information is t preset, such as t = 120 seconds; and, during the duration of the CDRX mode, The UE and the network side are in an RRC connection state. Optionally, the time difference between the time when the data service ends and the time that the network side sends the CDRX mode duration information is obtained is less than 30 seconds, and the specific time is determined by the network side according to the service condition of the UE.

Optionally, a CDRX timer is configured locally in the UE, and the duration information of the timer is configured to be a length of time corresponding to the CDRX mode duration information. When the execution start time of any data service of the UE arrives, the local CDRX timer is cleared. After the execution of any one of the foregoing data services, the CDRX mode duration information sent by the network side is re-established. The CDRX timer allocates duration information, and the duration information allocated for the CDRX timer is still the length of time t corresponding to the CDRX mode duration information.

Step 410: Determine, according to the running parameter of the UE, that the UE does not need to perform data service within a time length corresponding to the acquired CDRX mode duration information, and disconnects the RRC connection between the UE and the network side.

In the embodiment of the present invention, there are two methods for obtaining the operating parameters of the foregoing UE. The first mode is to obtain the running parameters of the UE by the network side, and the second mode is to acquire the operating parameters of the UE by the UE.

The operation parameters of the UE are obtained in the first manner as follows: The network side obtains the data traffic sent by the network side to the UE in the data service initiated by the network side according to the network performance parameter, and separately counts each item according to the data traffic volume. The service data corresponding to the data service arrives at the arrival time corresponding to the UE, and the arrival time corresponding to all the data services is used as an operation parameter of the UE, and the operation parameter of the UE is sent to the UE. For example, the network side obtains the arrival time corresponding to all the data services according to any one of the network performance parameters such as the UE running speed and the CELL ID (Cell ID).

The second method is used to obtain the running parameters of the UE as follows: The UE searches for a locally running application, acquires all applications that have data services with the network side, and counts the data service execution period of all the applications found above, and The data service execution period of all the found applications is used as the operating parameter of the UE. In the second mode, the number of applications running locally by the UE According to the characteristics of the application, the service execution period can be determined according to the characteristics of the application. For example, when the instant chat tool application is run locally in the UE, the data service execution period of the instant chat tool application is 3 minutes, that is, the UE executes the data every 3 minutes. The data service of the instant messaging tool application interacts with the business data corresponding to the data service on the network side.

According to the foregoing process, when the first mode is used, the obtained operating parameter of the UE is the arrival time corresponding to the data service initiated by the network side. When the second mode is used, the acquired operating parameter of the UE is determined by the UE. The execution cycle of the data service executed according to the locally running application. Therefore, the arrival time obtained by the first mode may be used as an operation parameter of the UE; and the execution period acquired according to the second mode may be used as an operation parameter of the UE.

When the operation parameter of the UE is obtained in the second manner, the UE searches for all applications that are running locally and have data services with the network side; the UE configures a timer for each application that is found, and according to the search The data service execution period of each application sets the corresponding execution time information for each of the configured timers; when any of the above timers expires, the UE can execute the data service of the application corresponding to the timer. . For example, if the execution period of the application-related data service is 3 minutes, the execution time information set for the timer configured for the application is 3 minutes, and 3 minutes after the current data service of the application is finished. Upon arrival, that is, after the configured timer of the application 1 expires, the corresponding data service of the application is executed.

In the embodiment of the present invention, the UE determines whether there is a data service to be executed in the time length corresponding to the CDRX mode duration information: according to the operating parameter of the UE, determining the execution start of each data service that the UE needs to perform At the moment, if it is determined that the determined execution start time does not fall within the time length corresponding to the acquired CDRX mode duration information, it is determined that the UE does not need to execute any data within the time length corresponding to the acquired CDR mode duration information. business. After the execution of the current data service (such as the first data service) of the UE, the CDRX duration information is obtained (for example, the time information is 120 seconds), that is, the duration information corresponding to the CDRX timer is 120 seconds, where the 120 Within seconds, there is the next data service (such as the second data service) that needs to be executed. After the next data service arrives, the CDRX timer is cleared (no longer counting), the UE executes the second data service, and when the second data service is executed, re-acquires the CDRX mode duration information (ie, 120 seconds). That is, after the UE completes the data service, the network side will re-issue the CDRX duration information for the UE. Therefore, in the embodiment of the present invention, only one execution start time is not included in the time length corresponding to the CDRX mode duration information, that is, the data length does not need to be executed within the time length corresponding to the CDRX mode duration information.

In the embodiment of the present invention, the UE determines whether there is at least one data service to be executed within the time length corresponding to the CDRX mode duration information, and if not, the UE sends an RRC disconnection request to the network side, and is based on the network side. The chain breaking instruction is allowed to disconnect the RRC connection with the network side; otherwise, the UE makes further judgments to determine the subsequent operations.

When the UE determines that the execution start time of the at least one data service is within the time length corresponding to the CDRX mode duration information, the UE performs a further determination, specifically: acquiring from the execution start time of the at least one data service An execution start time that is closest to the current time, and obtains a time difference between the current time and the acquired execution start time, where the time difference is the end time of the currently executed data service and the execution start time of the next data service For the duration of the first time, as shown in FIG. 5, after the Nth data service of the UE is completed (that is, after being awakened by the Nth time), the network side re-issues the CDRX mode duration information to the UE, if the first time After the execution of the data service is completed, the time length of the CDRX mode duration information is not reset, and the length of time corresponding to the CDRX mode duration information acquired after the execution of the Nth data service is completed. The length of time corresponding to the CDRX mode duration information acquired after any previous data service execution is the same, According to the time difference, each CDRX mode period duration, the energy consumption of each CDRX mode period, obtains the corresponding CDRX mode energy consumption when the CDRX mode is locally maintained; according to the time difference, establishes the energy consumption of the RRC connection, disconnects The energy consumption of the RRC connection, the duration of each DRX mode period, and the energy consumption of each DRX mode period, obtain the corresponding DRX mode energy consumption when the local CDRX mode is switched to the DRX mode, wherein when the UE disconnects from the network side After the RRC connection, the UE is in the DRX mode.

Specifically, the above CDRX mode energy consumption can be obtained by the following formula:

POWER— CDRX—Hold=(T/CDRX— CYCLE— T)*Power—CDRX

Where POWER_CDRX-Hold is the CDRX mode energy consumption; T is the time difference between the current time and the execution start time obtained above; CDRX-CYCLE-Τ is the duration of each CDRX mode cycle; Power—CDRX is for each CDRX The energy consumption of the mode period can be obtained through experiments. For example, after the energy consumption of each CDRX mode period of the UE is measured multiple times, the average value of the multiple measurements is obtained.

As shown in FIG. 5, if the UE does not perform the state switching, that is, the CDRX mode is maintained, the UE and the network side are always in the RRC connection state, and when the execution start time of the next data service to be executed arrives, the data service is executed. That is, there is no need to establish a process of the UE connecting to the network side RRC.

In addition, the above DRX mode energy consumption can be obtained by the following formula:

POWER_DRX_Hold=POWER_CDRX_RRC_OFF+POWER_CDRX_RRC_ ON+(T/DRX— CYCLE— T)*Power— DRX

Among them, POWER—DRX—Hold is the DRX mode energy consumption; POWER—CDRX—RRC—OFF is the energy consumption for disconnecting the RRC connection; POWER—CDRX—RRC—ON is the energy consumption for establishing the RRC connection; T is the current time and the above The time difference between the acquisition start times; DRX— CYCLE— Τ is the DRX mode period duration; Power—DRX is the energy consumption for each DRX mode period. This value can be obtained experimentally, such as for each DRX of the above UE. After the energy consumption of the mode period is measured multiple times, the average value of the multiple measurements is calculated.

Referring to FIG. 5, when the execution start time of at least one data service is included in the time length corresponding to the CDRX mode duration information, if the current data service performed by the UE ends, that is, the CDRX mode is switched to the DRX mode, The RRC connection between the UE and the network is disconnected. In this case, the "power consumption of disconnecting the RRC connection" needs to be consumed. When the execution start time of the data service to be executed is reached, the UE and the network side need to be re-established. RRC connection, which needs to be consumed at this time "Establishing energy consumption for RRC connections." Therefore, when the UE is switched from the CDRX mode to the DRX mode until the execution start time of the next data service to be performed arrives, the UE needs to "disconnect the RRC connection - maintain the DRX mode - waiting for the execution of the next data service to be executed. The RRC connection is established when the start time arrives, and the next data service that needs to be executed can be executed after the RRC connection is established.

Based on the foregoing process, comparing the foregoing CDRX mode energy consumption and the DRX mode energy consumption, and processing the RRC connection relationship between the UE and the network side according to the comparison result, specifically: when determining that the CDRX mode energy consumption is greater than the DRX mode energy consumption ( In the case of POWER_CDRX-Hold>POWER-DRX_Hold, the UE sends an RRC disconnection request to the network side, and disconnects the RRC connection with the network side according to the allowable broken link instruction fed back by the network side; when determining the CDRX mode When the power consumption is less than the DRX mode power consumption (ie, POWER_CDRX_Hold<POWER_DRX_Bold), the UE maintains an RRC connection with the network side.

With the above technical solution, when the UE is in the CDRX mode, the CDRX mode power consumption of the CDRX mode and the DRX mode function of the DRX mode are maintained and compared before the arrival of the execution start time corresponding to the next data service according to the above formula. Consumption, and according to the comparison result, whether to disconnect the RRC connection between the UE and the network side before the CDRX timer expires, that is, switch from the CDRX mode to the DRX mode.

If the timer is configured locally for each application that is running on the network side and the data service exists on the network side, after the UE disconnects the RRC connection with the network side, after any local timer expires, the timer corresponds to When the data service execution initial time of the application arrives, the RRC connection establishment request is sent to the network side, and the network side feeds back the permission connection establishment response message to the UE based on the RRC connection establishment request, and the UE acquires the permission connection establishment response message, and establishes a network with the network. The RRC connection on the side, that is, the UE is awakened, thereby executing the data service of the application corresponding to the above timer. With the above technical solution, the UE configures a corresponding timer for each application by learning the execution period of different applications, and controls the establishment of the RRC connection between the UE and the network side through a timer.

Therefore, each time the UE ends the currently executed first data service, it is followed by step 400~ Step 420: Detect whether there is an execution start time of the data service to be executed within a time length corresponding to the CDRX mode duration information that is sent by the network side. If yes, determine whether to disconnect the UE and the network side according to the execution start time. The RRC connection is disconnected until the UE performs the Nth data service, and determines that the execution start time of any data service that needs to be executed does not exist within the time length corresponding to the CDRX mode duration information delivered by the network side. Connect to the RRC on the network side.

Referring to FIG. 6, the following takes a specific application scenario, taking the operating parameters of the UE acquired by the UE as an example, and details the detailed process of reducing the power consumption of the UE:

Step 600: After the UE establishes an RRC connection with the network side, the first data service is performed, and after the first data service between the local network and the network side ends, the CDRX mode duration information sent by the network side is obtained, and The local CDRX timer sets the corresponding duration information.

In the embodiment of the present invention, when the UE does not establish an RRC connection with the network side, when the UE performs the data service, the RRC connection with the network side is first established. Set the corresponding duration information for the CDRX timer based on the CDRX mode duration information.

Step 610: The UE finds all applications running locally, acquires all applications that have data services on the network side from all running applications, and finds a data service execution period of each application.

Step 620: The UE obtains an execution start time of each of the foregoing data services according to the data service execution period of all the applications that are found.

Step 630: Determine whether the execution start time exists in the time length corresponding to the CDRX mode duration information, if yes, execute step 640; if not, execute step 660.

Step 640: Obtain, from all the foregoing moments, an execution start time of the second data service that is closest to the time of the first data service, and start from the execution start time of the first data service and the execution of the second data service. The time difference between the start time, and the CDRX mode parameter and the DRX mode parameter, obtain the CDXR mode energy consumption corresponding to the second data service and the DXR mode energy consumption.

In the embodiment of the present invention, the CDRX mode parameter includes each CDRX mode period duration, and each The energy consumption of the CDRX mode period; the DXR mode parameters include the energy consumption for establishing the RRC connection, the energy consumption for disconnecting the RRC connection, the duration of each DRX mode period, and the energy consumption for each DRX mode period.

Step 650: Determine whether the power consumption of the CDXR mode is greater than the power consumption of the DXR mode. If yes, go to step 660; otherwise, go to step 670.

Step 660: The UE sends an RRC disconnection request to the network side, and disconnects the RRC connection with the network side based on the allowable disconnection command sent by the network side.
