Example one

Referring to FIG. 2, which illustrates a method for wireless resource control connection provided by an embodiment of the present application. The method is applied to a mobile terminal. The method may include:

S201: Detect the running status of the third-party application; wherein the running status is used to characterize the running status of the third-party application;

S202: When the running state satisfies a preset acceleration policy, a random data packet is sent to the base station; wherein the random data packet is illegal Internet Protocol IP data sent to the base station at a packet data convergence protocol PDCP layer package;

S203: Based on the response of the base station to the random data packet, maintaining a radio resource control RRC connection with the base station.

Based on the technical solution shown in FIG. 2, it is applied to a mobile terminal by detecting the running status of a third-party application; wherein the running status is used to characterize the running status of the third-party application; when the running status meets a preset acceleration In the case of a policy, a random data packet is sent to the base station; wherein the random data packet is an illegal Internet Protocol IP data packet sent to the base station at a packet data convergence protocol PDCP layer; based on the base station for the random data The response of the packet maintains the radio resource control RRC connection with the base station; the mobile terminal can be maintained in a business state more, which saves the RRC connection re-establishment process, thereby reducing the transmission delay of data from the mobile terminal to the air interface , Improve the real-time nature of data transmission, and also improve the performance of mobile terminals.

For the technical solution shown in FIG. 2, in a possible implementation manner, when the running state meets a preset acceleration policy, sending a random data packet to a base station specifically includes:

When the running state satisfies that the third-party application is started for the first time and the third application has acceleration properties, sending a random data packet to a base station;

Alternatively, when the running state meets the acceleration attribute of the third-party application in the running state and runs again, a random data packet is sent to the base station.

It should be noted that the running status of the third-party application APP mainly includes: the first startup of the APP or the APP is already running; that is, if the APP is started for the first time and the APP has acceleration properties, or the APP is already running and When the acceleration attribute of the APP is run again, it can be shown that the running state of the APP satisfies a preset acceleration policy, and the mobile terminal can send random data packets to the base station.

For the technical solution shown in FIG. 2, in a possible implementation manner, the mobile terminal includes an application processor AP and a modem Modem, and when the running state meets a preset acceleration policy, a random data packet is sent. Send to the base station, including:

When the running state satisfies a preset acceleration policy, transmitting the demand for the acceleration attribute to the Modem through the AP;

Based on the requirements of the acceleration attribute, a random data packet is sent to the base station through the Modem.

It should be noted that the acceleration attributes of the APP include, but are not limited to, grabbing red envelopes, fighting a lot, grabbing orders for delivery, and dipping orders, etc. The data flow of these acceleration attributes is bursty, that is, there is data transmission for a period of time, followed by There may be no data transmission for a period of time. Generally speaking, when there is no data transmission, the network side (such as a base station, etc.) will release the RRC connection with the mobile terminal, leaving the mobile terminal in an idle idle state; however, these acceleration properties need to have higher real-time performance. It is hoped that the mobile terminal is more in the business state, which will save the transmission delay brought by the RRC reconstruction process; when it is detected that the running state meets the preset acceleration strategy, that is, the APP has the requirement of acceleration properties, the mobile terminal ’s The application processor AP transmits the demand for the acceleration attribute to the modem, and then the modem sends a random data packet to the base station to maintain the RRC connection, thereby avoiding the transmission delay caused by the RRC reconstruction process.

Referring to FIG. 3, which shows a schematic diagram of the composition structure of a legitimate IP data packet frame. As can be seen from FIG. 3, according to the protocol, the Data part should be a normal IP data packet. However, in the embodiment of the present application, the The random data packet is an illegal IP data packet, such as a 1-byte data packet. In this way, after the random data packet is received by the base station, it can be directly discarded by the base station, and the random data packet does not need to pass through the charging unit, that is, The transmission of the random data packet does not generate charging.

Then after the RRC connection establishment process ends, that is, after the RRC connection with the base station is implemented, the mobile terminal may start to send a random data packet to the base station based on the established RRC connection.

For the technical solution shown in FIG. 2, in a possible implementation manner, the sending a random data packet to a base station specifically includes:

Send the random data packet to the base station in a periodic transmission mode; wherein, the periodic transmission mode is to transmit at a preset time interval.

It should be noted that, in order to maintain a radio resource control RRC connection with the base station, the preset time interval needs to be less than a preset time threshold. Wherein, the preset time interval refers to the duration of the mobile terminal's pre-configured interval to send random data packets to the base station, and the preset time threshold refers to the mobile terminal's preset to maintain the RRC connection with the base station and no data transmission is allowed. The maximum interval time, for example, the preset time interval can be set to 8 seconds or 10 seconds, and the preset time threshold can be set to 15 seconds, which is not specifically limited in this embodiment of the present application. For example, suppose the preset time interval is 10s, and the preset time threshold is 15 seconds. That is, at the PDCP layer, the mobile terminal will send random data packets to the base station every 10s; because of the time interval Less than the preset time threshold, the random data packet is periodically sent at 10s intervals, and based on the response of the base station to the random data packet, the RRC connection between the mobile terminal and the base station is maintained, so that the mobile terminal is in a business state.

For the technical solution shown in FIG. 2, in a possible implementation manner, after the maintaining a radio resource control RRC connection with the base station, the method further includes:

Receiving the RRC connection release message sent by the base station;

Based on the response to the RRC connection release message, the RRC connection with the base station is disconnected.

It should be noted that, in order to reduce the transmission delay caused by the RRC connection re-establishment process, the mobile terminal can also configure it based on the random data packet sending period interval provided by the application processor and the corresponding value of the timeout timer Timer. The corresponding value of interval refers to the aforementioned preset time interval, which is convenient for periodic sending of random data packets; the corresponding value of Timer refers to the aforementioned preset time period, which is convenient for deciding whether to stop sending random data packets, which can be avoided. Waste of wireless resources. For example, suppose the Timer is configured for 4 minutes and the interval is configured for 10 seconds. When the mobile terminal implements an RRC connection with the base station, the mobile terminal starts sending random data packets, and at the same time, the Timer starts timing. Within 4 minutes, the mobile The terminal can always send random data packets to the base station at 10s intervals to keep the mobile terminal in a business state; however, when the timer timing meets 4 minutes, the mobile terminal will stop sending random data packets to the timing timeout time. Base station; when the mobile terminal stops sending random data packets so that the base station considers that there is no data transmission during this time, the base station will release the RRC connection and send an RRC connection release message to the mobile terminal, In response to the RRC connection release message, the RRC connection with the base station is disconnected, so that the mobile terminal changes from a service state to an idle state.

It should also be noted that when the mobile terminal again detects that the running status of the third-party application satisfies the preset acceleration policy, the mobile terminal will again send random data packets to the base station to maintain the RRC connection with the base station; thus making the mobile terminal more The ground is in a business state, which saves the RRC connection re-establishment process and improves the real-time performance of data transmission.

This embodiment provides a wireless resource control connection method. The method is applied to a mobile terminal by detecting a running state of a third-party application; wherein the running state is used to characterize a running situation of the third-party application; when the When the running status satisfies a preset acceleration policy, a random data packet is sent to the base station; wherein, the random data packet is an illegal Internet protocol IP data packet sent to the base station at a packet data convergence protocol PDCP layer; based on the In response to the random data packet, the base station maintains a radio resource control RRC connection with the base station; the mobile terminal can be maintained in a service state more, and the RRC connection re-establishment process is saved, thereby reducing data from the mobile terminal. The transmission delay to the air interface improves the real-time nature of data transmission and also improves the performance of the mobile terminal.

In this way, after the random data packet is received by the base station, the base station parses the random data packet. If the parsing fails, the random data packet can be directly discarded by the base station, and the random data packet does not need to pass the charging unit, that is, , The transmission of the random data packet does not generate charging.

If the preset time threshold is set to 15 seconds, the length of time during which the base station has not received the random data packet has reached 15 seconds, that is, the length of time during which the base station does not receive the random data packet has met the preset time threshold, and the base station will Release the RRC connection, stop receiving random data packets, and send an RRC connection release message to the mobile terminal; based on the mobile terminal's response to the RRC connection release message, the RRC connection with the mobile terminal is then disconnected, so that the mobile terminal The mobile terminal is changed from a service state to an idle state.

This embodiment provides a wireless resource control connection method. The method is applied to a base station and receives a random data packet sent by a mobile terminal. The random data packet is sent by the mobile terminal at a PDCP layer of a packet data convergence protocol. An illegal IP data packet; based on the response to the random data packet, maintaining a radio resource control RRC connection with the mobile terminal; can make the mobile terminal more in a business state, saving the RRC connection re-establishment process Therefore, the transmission delay of data from the mobile terminal to the air interface is reduced, and the real-time nature of data transmission is improved.

Example three

Based on the same inventive concept of the foregoing embodiment, refer to FIG. 5, which illustrates a detailed flow of a radio resource control connection method provided by an embodiment of the present application. An exemplary scenario of the method may refer to FIG. 1A. Taking the red packet grabbing in WeChat application as an example, based on the schematic diagram of the wireless communication system architecture shown in FIG. 1A, the detailed process may include:

S501: The mobile terminal detects the running status of the third-party application; wherein the running status is used to characterize the running status of the third-party application;

S502: When the running status meets a preset acceleration policy, the mobile terminal transmits the demand for the acceleration attribute to the modem Modem through the application processor AP;

For example, taking the wireless communication system architecture shown in FIG. 1A as an example, when the mobile terminal 104 detects that the WeChat application is running and starts to grab red packets in the WeChat application, because the red packet grabbing is an accelerated attribute, that is, the mobile terminal The running state of the mobile terminal satisfies the preset acceleration strategy. At this time, the mobile terminal 104 transmits the demand for the acceleration attribute to the modem Modem through its own application processor AP, so as to subsequently maintain the RRC connection between the mobile terminal 104 and the base station 101.

S503: The mobile terminal sends an RRC connection establishment request message to the base station.

S504: The base station returns an RRC connection establishment response message to the mobile terminal.

S505: The mobile terminal sends the RRC connection establishment completion message to the base station.

S506: Realize the RRC connection between the base station and the mobile terminal;

For example, taking the wireless communication system architecture shown in FIG. 1A as an example, in order to achieve an RRC connection between the mobile terminal 104 and the base station 101, the mobile terminal 104 first needs to send an RRC connection establishment request message to the base station 101, and then the base station 101 is based on The received RRC connection establishment request message returns an RRC connection establishment response message to the mobile terminal 104; the mobile terminal 104 establishes an RRC connection based on the received RRC connection establishment response message, and then the mobile terminal 104 sends an RRC connection establishment complete message to the base station 101 Finally, the base station 101 implements the RRC connection between the base station 101 and the mobile terminal 104 based on the received RRC connection establishment completion message; based on the established RRC connection, the mobile terminal 104 can perform data transmission to the base station 101.

S507: When the RRC connection with the mobile terminal is implemented, the timeout timer configured by the mobile terminal starts timing, and the mobile terminal sends a random data packet to the base station in a periodic transmission mode through the Modem;

S508: The base station receives a random data packet sent by the mobile terminal.

S509: the base station parses the received random data packet;

S510: if the random data packet analysis fails, the base station discards the random data packet;

S511: Based on the response of the base station to the random data packet, the mobile terminal maintains an RRC connection with the base station;

For example, the wireless communication system architecture shown in FIG. 1A is still used as an example. In combination with the above example, when the RRC connection between the base station 101 and the mobile terminal 104 is implemented, the timeout timer configured by the mobile terminal 104 starts and starts counting. At the same time, the mobile terminal 104 sends a random data packet to the base station 101 in a periodic transmission mode through the Modem; it is assumed that the timeout timer configured by the mobile terminal 104 is 4 minutes and the transmission period of the random data packet is 10 seconds. Within minutes, the mobile terminal 104 sends random data packets at 10-second intervals, and the base station 101 receives the random data packets; after the base station 101 receives the random data packets, it performs analysis. Since the random data packets are illegal IP data packets, the analysis It is a failure. At this time, the base station 101 directly discards the random data packet, and the random data packet does not pass the charging unit, which also means that the transmission of the random data packet does not generate charging; based on the reception of the random data packet by the base station 101, The mobile terminal 104 maintains the RRC connection with the base station 101, so that the mobile terminal 104 is more maintained in a business state, and the RRC connection is saved. Reconstruction process, reducing the data transmission delay from the mobile terminal to the air interface, improved real-time data transmission.

S512: The mobile terminal stops sending the random data packet to the base station at the timeout time counted by the timeout timer;

S513: If the duration that the base station does not receive the random data packet meets a preset time threshold, the base station releases the RRC connection and stops receiving the random data packet;

S514: The base station sends the RRC connection release message to the mobile terminal.

S515: Disconnect the RRC connection between the base station and the mobile terminal based on the response of the mobile terminal to the RRC connection release message.

For example, the wireless communication system architecture shown in FIG. 1A is still taken as an example. In combination with the above example, it is assumed that the preset time threshold is 15 seconds. Since the timeout timer configured by the mobile terminal 104 is 4 minutes, within 4 minutes. The mobile terminal 104 sends random data packets to the base station 101 at 10-second intervals; when the timeout timer reaches 4 minutes, that is, at the timeout time of the timeout timer, the mobile terminal 104 stops sending random data to the base station 101 At this time, the base station 101 did not receive a random data packet. When the length of time during which the base station 101 did not receive a random data packet satisfies 15 seconds, the base station 101 defaulted to no data transmission during this time. Data packet; at the same time, the base station 101 will also send an RRC connection release message to the mobile terminal 104; then the mobile terminal 104 responds based on the received RRC connection release message, so that the RRC connection between the base station 101 and the mobile terminal 104 is disconnected , So that the mobile terminal changes from a business state to an idle state.

Through the foregoing embodiments, the specific implementation of the foregoing embodiments is described in detail. It can be seen from the foregoing that the technical solutions of the foregoing embodiments can enable the mobile terminal to be more maintained in a business state and save RRC connection reconstruction. Process, thereby reducing the transmission delay of data from the mobile terminal to the air interface, improving the real-time nature of data transmission, and improving the performance of the mobile terminal.
