Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

As used herein, "plurality" refers to two or more. "And/or", which describes the association relationship of the associated objects, means that there can be three kinds of relationships, for example, A and/or B, which can mean that A exists alone, A and B exist at the same time, and B exists alone. The character "/" generally indicates that the associated objects are an "or" relationship.

For the convenience of understanding, the terms involved in the embodiments of the present invention are explained below.

Connected state: Also known as service state, when the terminal completes camping in the cell, the terminal enters the idle state (idle); when the terminal subsequently completes the random access procedure (establishing an RRC connection), the terminal enters the connected state. If the terminal in the connected state does not transmit data with the access network device for a long time, the access network device will release the RRC connection with the terminal.

Application Processor (AP): refers to the processor used to run the operating system and application programs in the terminal, excluding communication with the access network equipment; the processor used for communication with the access network equipment is called Baseband chip (modem), or baseband processor (Baseband Processor, BP). Communication between the AP and the modem is performed through shared memory. Alternatively, the application processor and baseband processor may be integrated into a single processor.

Please refer to FIG. 1 , which shows a schematic structural diagram of a mobile communication system provided by an embodiment of the present invention. The mobile communication system may be an LTE system or a fifth generation mobile communication technology (the 5th generation mobile communication, 5G), also known as a New Radio (New Radio, NR) system. The mobile communication system includes: an access network device 120 and a terminal 140 .

The access network device 120 can be a base station, and the base station can be used to convert the received radio frame and the IP packet to each other, and can also coordinate the attribute management of the air interface. For example, the base station may be an evolved base station (eNB or e-NodeB, evolutional Node B) in LTE, or a base station using a centralized distributed architecture in a 5G system.

The access network device 120 and the terminal 140 establish a wireless connection through a wireless air interface. Optionally, the wireless air interface is a wireless air interface based on the LTE standard; alternatively, the wireless air interface is a wireless air interface based on a 5G standard, for example, the wireless air interface is NR; or, the wireless air interface can also be a 5G-based next generation mobile interface The wireless air interface of the communication network technology standard.

Terminal 140 may be a device that provides voice and/or data connectivity to a user. The terminal may communicate with one or more core networks via a Radio Access Network (RAN), and the terminal 140 may be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, For example, it may be a portable, pocket-sized, hand-held, computer built-in or vehicle mounted mobile device. For example, Subscriber Unit, Subscriber Station, Mobile Station, Mobile Station, Remote Station, Access Point, Remote Terminal, Access Terminal, User Terminal, User Agent, User Device, or User Equipment.

The RRC connection release method provided by each embodiment of the present invention is applied to the mobile communication system shown in FIG. 1 .

After the terminal establishes an RRC connection with the access network device, it can perform data transmission with the access network device. And in order to avoid the radio resource being occupied for a long time, after the terminal and the access network device have no data transmission for a preset period of time, the access network device releases the RRC connection with the terminal. In a possible application scenario, after the terminal enters the RRC idle state from the RRC connected state, when the terminal needs to send service data to the access network device, the RRC connection needs to be re-established. For services with high delay requirements, the uplink service data transmission delay caused by reestablishing the RRC connection will have a greater impact on the service.

In order to reduce the impact of RRC reconstruction on low-latency services, in this embodiment of the present invention, the terminal detects the currently running application, and when detecting the running application with the low-latency attribute, sends an RRC release to the access network device Period reconfiguration signaling requests access network equipment to configure a longer RRC release period, thereby reducing the probability of RRC connection release and thus reducing the probability of RRC connection re-establishment, which is described below using an illustrative embodiment.

Please refer to FIG. 2 , which shows a flowchart of an RRC connection release method provided by an embodiment of the present invention. In this embodiment, the RRC connection release method is used in the mobile communication system shown in FIG. 1 as an example for description. The following steps may be included.

In step 201, the terminal identifies whether a preset application program is running, and the preset application program refers to an application program with a low-latency 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 program running in the foreground and the background is a preset application program every predetermined time interval.

Among them, the application with low latency attribute refers to the application with high demand for service latency (that is, high real-time requirement), for example, the application with the service latency lower than 150ms is the one with low latency attribute application.

Optionally, the preset application program is an application program that supports low-latency services. For example, the preset application is an application that supports a red envelope grabbing function or a like function, or the preset application is a travel application with an order grabbing function, and so on. The embodiment of the present invention does not limit the specific type of the preset application program.

Step 202, if a preset application is running, the terminal sends RRC release cycle reconfiguration signaling to the access network device through the modem, and the RRC release cycle reconfiguration signaling includes the target RRC release cycle.

When a preset application is running, in order to reduce the impact of RRC reconstruction on service delay, the terminal sends an RRC release cycle reconfiguration signaling to the access network device through its modem, requesting the access network device to reconfigure the terminal RRC release cycle length of time.

Optionally, the RRC release period reconfiguration request includes a target RRC release period, and the target RRC release period is greater than the original (default) RRC release period. For example, when the original RRC release period is 1000ms, the target RRC release period is 5000ms. .

In other possible implementations, the terminal pre-agrees with the access network device at least two RRC release periods, wherein the first RRC release period is greater than the second RRC release period. Normally, the terminal and the access network device use the first RRC release period by default. When the RRC release cycle needs to be reconfigured, the reconfiguration request sent by the terminal to the access network device through the operator server includes the RRC release cycle switching instruction to instruct the access network device to use the second RRC release cycle to replace the first RRC release cycle .

Step 203, the access network device receives the RRC release cycle reconfiguration signaling.

Correspondingly, the access network device receives the RRC release cycle reconfiguration signaling sent by the terminal modem.

Optionally, after receiving the RRC release cycle reconfiguration signaling, the access network device first authenticates the signaling to determine whether the current terminal has the authority to reconfigure the RRC release cycle (that is, whether the terminal is an authorized terminal). If it has the authority, the access network device further executes the following step 204; if it does not have the authority, the RRX release cycle reconfiguration signaling is ignored.

Step 204, the access network device reconfigures the RRC release cycle according to the RRC release cycle reconfiguration signaling.

Optionally, after receiving the RRC release cycle reconfiguration signaling, the access network device reconfigures its own RRC release cycle according to the target RRC release cycle included in the signaling, and sets a timer according to the target RRC release cycle.

Step 205, when the target RRC release period is reached, the access network device delivers the RRC connection release signaling to the terminal.

In a possible implementation, the access network device sets a timer according to the target RRC release period, and when the timer reaches the target RRC release period (that is, there is no data transmission within the target RRC release period), sends an RRC to the terminal Connection release (RRC ConnectionRelease) signaling, instructing the terminal to release the RRC connection.

Compared with the release of the RRC connection based on the original RRC release period, after the target RRC release period is adopted, the RRC connection between the terminal and the access network device is maintained for a longer time in the absence of data transmission. Correspondingly, the terminal releases the RRC connection. The probability is lower, that is, the probability that the terminal needs to reestablish the RRC connection when sending service data is reduced. For low-latency services, the delay of low-latency service data can be significantly reduced.

Step 206, the terminal receives the 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.

After the terminal releases the RRC connection, it enters the RRC idle state.

Optionally, after the terminal enters the RRC idle state, it reestablishes the RRC connection with the access network device every predetermined time interval, and sends the RRC release cycle reconfiguration signaling to the access network device through the above step 202, so as to recover by means of the timing reconnection mechanism. RRC connection, so that the terminal maintains a long RRC connection state. For example, the predetermined time interval is 20s.

To sum up, in this embodiment, when an application with a 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, instructing the access network device to reconfigure the RRC release period. period, so that the access network device releases the RRC connection with the terminal when the target RRC release period is reached; since the target RRC release period is longer than the original RRC release period, after reconfiguration, in the case of no service data transmission, the terminal The time in the connected state is prolonged, thereby reducing the probability of the terminal reestablishing the RRC connection, and achieving the effect of reducing the service delay.

In a possible application scenario, when all terminals can request the access network device to reconfigure the RRC release period, a large number of reconfiguration signaling will cause excessive processing pressure on the access network device and affect the performance of the communication system. In order to avoid the problem of excessive processing pressure on the access network equipment, an authentication mechanism is introduced into the above communication system, that is, the access network equipment only responds to the RRC release cycle reconfiguration signaling sent by the authorized terminal. Illustrative embodiments are used for description below.

Please refer to FIG. 3 , which shows a flowchart of an RRC connection release method provided by another embodiment of the present invention. This embodiment is described by taking the RRC connection release method used in the mobile communication system shown in FIG. The method may include the following steps.

In step 301, the terminal identifies whether a preset application program is running, and the preset application program refers to an application program with a low latency attribute.

In a possible implementation manner, the terminal obtains the application identifier of the application program with the low-latency attribute in advance, and obtains the preset application identifier set. When recognizing whether the preset application is currently running, the terminal detects whether the application identifier of the currently running application belongs to the preset application identifier set; if the application identifier of the currently running application belongs to the preset application identifier set, it is determined that there is a preset running application. application; instead, the terminal determines that the preset application is not running.

Optionally, after the application identifiers in the preset application identifier set are reported to the background server by each terminal, the background server is aggregated and generated. For example, the preset application identifier set includes: instant messaging application A, microblog application B, and travel application C.

In another possible implementation, the terminal detects whether the currently running application receives predetermined service data, where the predetermined service data refers to the service data of the low-latency service; if the currently running application receives the predetermined service data, it determines to run There is a preset application; on the contrary, the terminal determines that the preset application is not running.

Optionally, the terminal analyzes the service data of the low-latency service in advance to obtain data characteristics of the low-latency service data. When receiving service data, it detects whether the service data is predetermined service data based on the data characteristics. Wherein, the data feature includes a specific data identifier, a characteristic data field, a specific data format, and the like.

In other possible implementation manners, the terminal may further determine whether the application is a preset application according to the service type of the service supported by the application, or according to the application type of the application, which is not limited in this embodiment of the present invention.

Step 302, if a preset application is running, the terminal sends an RRC release cycle reconfiguration request to the modem through the AP, and the RRC release cycle reconfiguration request includes the target RRC release cycle; the modem is used to generate an RRC according to the RRC release cycle reconfiguration request. Release period reconfiguration signaling.

When identifying that a preset application program is currently running, the terminal calls the AP to initiate a request for reconfiguring the RRC release period, and sends the request to the modem through the shared memory. Optionally, the request includes the target RRC release period. After receiving the request, the modem further generates RRC release cycle reconfiguration signaling that can be identified by the access network device

For the method of generating the RRC release cycle reconfiguration signaling, in a possible implementation, the authorized terminal pre-agrees with the access network equipment the signaling format of the RRC release cycle reconfiguration signaling; The reserved signaling field (reserve element) in the command is used to generate RRC release cycle reconfiguration signaling that conforms to the signaling format. The RRC release cycle reconfiguration signaling is the customized signaling between the authorized terminal and the access network device. Optionally, the signaling formats of the RRC release cycle reconfiguration signaling used by terminals produced by different terminal manufacturers are the same or different, and both need to be pre-agreed with the access network equipment.

Step 303, the terminal sends the RRC release cycle reconfiguration signaling through the modem.

Step 304, the access network device receives the RRC release cycle 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 cycle reconfiguration signaling, the access network device determines whether the current terminal is an authorized terminal by detecting the reserved signaling field in the signaling. If it is detected that the reserved signaling field is a signaling field pre-agreed with the authorized terminal (that is, the RRC release cycle reconfiguration signaling conforms to the signaling format), the access network device determines that the current terminal is an authorized terminal, and executes the following steps 306: If the reserved signaling field is not a signaling field pre-agreed with the authorized terminal, it is determined that the current terminal is not authorized and cannot use the RRC release period reconfiguration service.

In other possible implementations, in order to allow only a specified application to use the RRC release cycle reconfiguration service, the RRC release cycle reconfiguration signaling also includes the application identifier of the application. Correspondingly, the access network device is based on the application identifier. Determine whether the current application is an authorized application; in order to allow only specified users to use the RRC release cycle reconfiguration service, the RRC release cycle reconfiguration signaling also includes the application account or terminal number corresponding to the application, correspondingly, the access network The device determines whether the current user has an authorized account according to the application account or terminal number. This embodiment of the present invention does not limit this.

Step 306, if the terminal is an authorized terminal, the access network device reconfigures the RRC release cycle according to the RRC release cycle reconfiguration signaling.

The implementation manner of this step is similar to the foregoing step 204, and details are not described herein again in this embodiment.

Step 307, when the target RRC release period is reached, the access network device delivers the RRC connection release signaling to the terminal.

The implementation manner of this step is similar to that of step 205, and details are not described herein again in this embodiment.

Optionally, the access network device restores the original RRC release period while delivering the RRC connection release signaling. In the subsequent process, the access network device 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 manner of the foregoing steps 308 to 309 is similar to the foregoing steps 206 to 207, and details are not described herein again in this embodiment.

In this embodiment, an authentication mechanism is introduced, so that the access network device only responds to the RRC release cycle reconfiguration signaling sent by the authorized terminal, so as to avoid any terminal being able to reconfigure the RRC release cycle at will, resulting in excessive processing pressure on the access network device This improves the performance and stability of the communication system.

It should be noted that, in the above-mentioned embodiments, the steps of taking the terminal as the execution subject can be independently implemented as the RRC release period configuration method on the terminal side, and the steps of using the access network device as the execution subject can be independently implemented as the access network device side.
