Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Reference herein to "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
For convenience of understanding, terms referred to in the embodiments of the present invention are explained below.
Connection state: also called as a service state, when the terminal finishes residing in a cell, the terminal enters an idle state (idle); when the terminal subsequently completes the random access procedure (establishes RRC connection), the terminal enters the connected state. If the terminal in the connected state does not perform data transmission with the access network device for a long time, the access network device releases the RRC connection with the terminal.
Application Processor (AP): the processor in the terminal is used for running an operating system and an application program, and does not communicate with the access network equipment; and the Processor used to communicate with the access network device is referred to as a Baseband chip (modem), or Baseband Processor (BP). The AP and the modem communicate with each other through a shared memory (share memory). Alternatively, the application processor and the baseband processor may be integrated into a single processor.
Referring to fig. 1, a schematic structural diagram of a mobile communication system according to an embodiment of the present invention is shown. The mobile communication system may be an LTE system or a fifth generation mobile communication technology (5G), which is also called a New Radio (NR) system. The mobile communication system includes: access network device 120 and terminal 140.
The access network device 120 may be a base station, which may be configured to convert the received radio frame and IP packet message into each other, and may coordinate attribute management of the air interface. For example, the base station may be an evolved Node B (eNB or e-NodeB) in LTE, or a base station in 5G system that adopts a centralized distributed architecture.
The access network device 120 and the terminal 140 establish a wireless connection over a wireless air interface. Optionally, the wireless air interface is based on an LTE standard; or the wireless air interface is a wireless air interface based on a 5G standard, for example, the wireless air interface is NR; alternatively, the wireless air interface may be a wireless air interface based on a 5G next generation mobile communication network technology standard.
The RRC connection release method provided by the various embodiments of the present invention is used in the mobile communication system shown in fig. 1.
After the terminal establishes RRC connection with the access network equipment, data transmission can be carried out with the access network equipment. And in order to avoid that the wireless resources are occupied for a long time, after no data transmission between the terminal and the access network equipment reaches a preset time, the access network equipment releases the RRC connection with the terminal. In a possible application scenario, after the terminal enters an RRC idle state from an RRC connected state, when the terminal needs to send service data to the access network device, the RRC connection needs to be reestablished. For services with higher delay requirements, the uplink service data transmission delay caused by the reestablishment of the RRC connection will have a greater impact on the services.
In order to reduce the influence of RRC reestablishment on the low latency service, in the embodiment of the present invention, the terminal detects the currently running application program, and when detecting the application program with the low latency attribute, requests the access network device to configure a longer RRC release period by sending an RRC release period reconfiguration signaling to the access network device, so as to reduce the probability of RRC connection release and further reduce the probability of RRC connection reestablishment, which is described below with an exemplary embodiment.
Referring to fig. 2, a flowchart of an RRC connection release method according to an embodiment of the present invention is shown, where the RRC connection release method is used in the mobile communication system shown in fig. 1 as an example, and the method may include the following steps.
In step 201, the terminal identifies whether a preset application program runs, where the preset application program refers to an application program with a low delay attribute.
Optionally, when detecting that the application program is started, the terminal detects whether the currently started application program is a preset application program; or, the terminal detects whether the application programs running in the foreground and the background are preset application programs at preset time intervals.
The application with the low latency attribute refers to an application with a high service latency requirement (i.e., a high real-time requirement), for example, an application requiring a service latency of less than 150ms is an application with a low latency attribute.
Optionally, the preset application is an application supporting a low-latency service. For example, the preset application is an application supporting a red envelope grabbing function or a like function, or the preset application is a travel application having an order grabbing function, and the like. The embodiment of the present invention does not limit the specific type of the preset application program.
Step 202, if the preset application program is running, the terminal sends an RRC release period reconfiguration signaling to the access network device through the modem, where the RRC release period reconfiguration signaling includes a target RRC release period.
When a preset application program runs, in order to reduce the influence of RRC reestablishment on service delay, the terminal sends an RRC release period reconfiguration signaling to the access network equipment through the modem of the terminal, and requests the access network equipment to reconfigure the duration of the RRC release period of the terminal.
Optionally, the RRC release period reconfiguration request includes a target RRC release period, and the target RRC release period is greater than an original (default) RRC release period. For example, when the original RRC release period is 1000ms, the target RRC release period is 5000 ms. .
In other possible embodiments, the terminal has agreed with the access network device at least two RRC release periods in advance, where the first RRC release period is greater than the second RRC release period. In general, the terminal and the access network device use the first RRC release period by default. When the RRC release period needs to be reconfigured, the reconfiguration request sent by the terminal to the access network device through the operator server includes an RRC release period switching indication, so as to instruct the access network device to replace the first RRC release period with the second RRC release period.
Step 203, the access network equipment receives the RRC release period reconfiguration signaling.
Correspondingly, the access network equipment receives RRC release period reconfiguration signaling sent by the terminal modem.
Optionally, after receiving the RRC release period reconfiguration signaling, the access network device first authenticates the signaling, so as to determine whether the current terminal has an authority to reconfigure the RRC release period (i.e., whether the terminal is an authorized terminal), and if so, the access network device further performs the following step 204; and if not, ignoring the RRX release period reconfiguration signaling.
Step 204, the access network device reconfigures the RRC release period according to the RRC release period reconfiguration signaling.
Optionally, after receiving the RRC release period reconfiguration signaling, the access network device reconfigures its own RRC release period according to a target RRC release period included in the signaling, and sets the timer according to the target RRC release period.
Step 205, when the target RRC release period is reached, the access network device issues an RRC connection release signaling to the terminal.
In a possible implementation manner, the access network device sets a timer according to the target RRC release period, and when the timer reaches the target RRC release period (i.e., no data transmission occurs in the target RRC release period), issues an RRC connection release (RRC ConnectionRelease) signaling to the terminal, and instructs the terminal to release the RRC connection.
Compared with the method for releasing the RRC connection based on the original RRC release period, after the target RRC release period is adopted, the time for keeping the RRC connection between the terminal and the access network equipment is longer under the condition of no data transmission, correspondingly, the probability for releasing the RRC connection by the terminal is lower, namely the probability for rebuilding the RRC connection when the terminal sends the service data is reduced, and the time delay of the low-delay service data can be obviously reduced for the low-delay service.
In step 206, the terminal receives an RRC connection release signaling sent by the access network device.
Step 207, the terminal releases the RRC connection according to the RRC connection release signaling.
And after the terminal releases the RRC connection, the terminal enters an RRC idle state.
Optionally, after entering the RRC idle state, the terminal reestablishes RRC connection with the access network device at predetermined time intervals, and sends an RRC release period reconfiguration signaling to the access network device through step 202, so as to recover the RRC connection by using a timing reconnection mechanism, so that the terminal maintains a longer RRC connection state. For example, the predetermined time interval is 20 s.
To sum up, in this embodiment, when the application with the low latency attribute is running, the terminal sends a reconfiguration signaling including the target RRC release period to the access network device through the modem, and instructs the access network device to reconfigure the RRC release period, so that the access network device releases the RRC connection with the terminal when the target RRC release period is reached; because the target RRC release period is greater than the original RRC release period, after reconfiguration, under the condition of no service data transmission, the time of the terminal in the connection state is prolonged, so that the probability of the terminal for reestablishing the RRC connection is reduced, and the effect of reducing service delay is achieved.
In a possible application scenario, when all terminals can request the access network device to reconfigure the RRC release period, a large amount of reconfiguration signaling will cause excessive processing pressure on the access network device, which affects the performance of the communication system. In order to avoid the problem of processing over-pressure by the access network equipment, an authentication mechanism is introduced into the communication system, that is, the access network equipment only responds to the RRC release period reconfiguration signaling sent by the authorized terminal. The following description will be made by using exemplary embodiments.
Referring to fig. 3, a flowchart of an RRC connection release method according to another embodiment of the present invention is shown, where the RRC connection release method is used in the mobile communication system shown in fig. 1 as an example, and the method may include the following steps.
Step 301, the terminal identifies whether a preset application program runs, wherein the preset application program refers to an application program with a low time delay attribute.
In a possible implementation manner, the terminal obtains the application identifier of the application program with the low delay attribute in advance, and obtains a preset application identifier set. When identifying whether the preset application program is currently operated or not, the terminal detects whether the application identifier of the currently operated application program belongs to a preset application identifier set or not; if the application identifier of the currently running application program belongs to the preset application identifier set, determining that the preset application program is running; in contrast, the terminal determines that the preset application is not run.
Optionally, after the application identifiers in the preset application identifier set are reported to the background server by each terminal, the application identifiers are generated by the background server in a summary manner. For example, the preset application identifier set includes: the system comprises an instant messaging application program A, a microblog application program B and a trip application program C.
In another possible implementation manner, the terminal detects whether the currently running application program receives predetermined service data, where the predetermined service data refers to service data of a low-latency service; if the currently running application program receives the preset service data, determining that a preset application program runs; in contrast, the terminal determines that the preset application is not run.
Optionally, the terminal analyzes the service data of the low-latency service in advance to obtain the data characteristics of the low-latency service data, and detects whether the service data is the predetermined service data based on the data characteristics when the service data is received. Wherein the data characteristics include a specific data identification, a characteristic data field, a specific data format, and the like.
In other possible implementations, the terminal may further determine whether the service type of the service supported by the application program is a preset application program according to the service type of the service supported by the application program, or according to the application type of the application program, which is not limited in the embodiment of the present invention.
Step 302, if a preset application program runs, the terminal sends an RRC release period reconfiguration request to the modem through the AP, wherein the RRC release period reconfiguration request comprises a target RRC release period; and the modem is used for generating RRC release period reconfiguration signaling according to the RRC release period reconfiguration request.
When the preset application program is identified to be operated currently, the terminal calls the AP to initiate a request for reconfiguring an RRC release period, and sends the request to the modem through the shared memory. Optionally, the request includes a target RRC release period. After receiving the request, the modem further generates RRC release period reconfiguration signaling which can be identified by the access network equipment
Aiming at the mode of generating the RRC release period reconfiguration signaling, in a possible implementation mode, an authorization terminal and access network equipment agree in advance on a signaling format of the RRC release period reconfiguration signaling; in the signaling generation stage, the modem generates an RRC release period reconfiguration signaling conforming to the signaling format by setting a reserved signaling field (reserved element) in the signaling, where the RRC release period reconfiguration signaling is a customized signaling between the authorized terminal and the access network device. Optionally, signaling formats of RRC release period reconfiguration signaling adopted by terminals produced by different terminal manufacturers are the same or different, and all the signaling formats need to be agreed with the access network device in advance.
Step 303, the terminal sends RRC release period reconfiguration signaling through the modem.
In step 304, the access network device receives RRC release period reconfiguration signaling.
Step 305, the access network device detects whether the terminal is an authorized terminal according to the reserved signaling field in the RRC release period reconfiguration signaling.
After receiving the RRC release period reconfiguration signaling, the access network equipment determines whether the current terminal is an authorized terminal by detecting a reserved signaling field in the signaling. If the reserved signaling field is detected to be a signaling field agreed with the authorized terminal in advance (namely, the RRC release period reconfiguration signaling conforms to the signaling format), the access network equipment determines that the current terminal is the authorized terminal, and executes the following step 306; if the reserved signaling field is not the signaling field agreed with the authorized terminal in advance, the current terminal is determined to be unauthorized and cannot use the RRC to release the periodic reconfiguration service.
In other possible embodiments, in order to implement that only the designated application is allowed to use the RRC release periodic reconfiguration service, the RRC release periodic reconfiguration signaling further includes an application identifier of the application, and accordingly, the access network device determines whether the current application is an authorized application according to the application identifier; in order to allow only the designated user to use the RRC release period reconfiguration service, the RRC release period reconfiguration signaling further includes an application account or a terminal number corresponding to the application program, and accordingly, the access network device determines whether the current user has an authorized account according to the application account or the terminal number. The embodiments of the present invention are not limited thereto.
Step 306, if the terminal is an authorized terminal, the access network device reconfigures the RRC release period according to the RRC release period reconfiguration signaling.
The implementation of this step is similar to that of step 204, and this embodiment is not described herein again.
Step 307, when the target RRC release period is reached, the access network device issues an RRC connection release signaling to the terminal.
The implementation of this step is similar to step 205, and this embodiment is not described herein again.
Optionally, the access network device recovers the original RRC release period while issuing the RRC connection release signaling. In the subsequent process, the access network equipment releases the RRC connection with the terminal according to the original RRC release period.
Step 308, the terminal receives the RRC connection release signaling sent by the access network device.
Step 309, the terminal releases the RRC connection according to the RRC connection release signaling.
The implementation of steps 308 to 309 is similar to that of steps 206 to 207, and this embodiment is not repeated herein.
In the embodiment, the access network equipment only responds to the RRC release period reconfiguration signaling sent by the authorized terminal by introducing the authentication mechanism, so that the problem that the processing pressure of the access network equipment is overlarge because any terminal can randomly reconfigure the RRC release period is avoided, and the performance and the stability of the communication system are improved.
It should be noted that, in each of the above embodiments, the step taking the terminal as an execution main body may be separately implemented as an RRC release period configuration method on the terminal side, and the step taking the access network device as an execution main body may be separately implemented as an RRC release period configuration method on the access network device side, which is not described herein again.
