With reference to the schematic diagram of the architecture of the wireless communication system shown in fig. 1A, an interaction process of third-party APP service data of a mobile terminal and a network device (such as a base station, an operator server, and the like) includes access network delay from a mobile phone to a network air interface, and time consumption for transmitting Internet Protocol (IP) data from an access network to the operator server. In order to improve the real-time performance of data transmission, the following describes embodiments of the present invention in detail with reference to the accompanying drawings.

Example one

Referring to fig. 2, it illustrates a radio resource control connection method provided in an embodiment of the present invention, which is applied to a mobile terminal, and the method may include:

s201: detecting the running state of a third-party application; wherein the running state is used for representing the running condition of the third-party application;

s202: when the running state meets a preset acceleration strategy, sending a random data packet to a base station; the random data packet is a non-legal Internet Protocol (IP) data packet which is sent to the base station at a Packet Data Convergence Protocol (PDCP) layer;

s203: maintaining a radio resource control, RRC, connection with the base station based on the base station's response to the random data packet.

Based on the technical scheme shown in fig. 2, the method is applied to the mobile terminal, and the running state of the third-party application is detected; wherein the running state is used for representing the running condition of the third-party application; when the running state meets a preset acceleration strategy, sending a random data packet to a base station; the random data packet is a non-legal Internet Protocol (IP) data packet which is sent to the base station at a Packet Data Convergence Protocol (PDCP) layer; maintaining a radio resource control, RRC, connection with the base station based on the base station's response to the random data packet; the mobile terminal can be maintained in a service state more, and the RRC connection reconstruction process is saved, so that the transmission delay of data from the mobile terminal to an air interface is reduced, the real-time performance of data transmission is improved, and the use performance of the mobile terminal is also improved.

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

when the running state meets the requirement that the third-party application is started and run for the first time and the third application has an acceleration attribute, sending a random data packet to a base station;

or when the running state meets the requirement that the acceleration attribute of the third-party application in the running state runs again, sending a random data packet to the base station.

It should be noted that the operation state of the third-party application APP mainly includes: the APP is started to run for the first time or the APP is in a running state; that is to say, if the APP is started to operate for the first time and the APP has the acceleration attribute, or the APP is already in the operating state and the acceleration attribute of the APP operates again, it can be indicated that the operating state of the APP satisfies the preset acceleration policy, and the mobile terminal can send the random data packet 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, and when the operation state satisfies a preset acceleration policy, the sending a random data packet to the base station specifically includes:

when the running state meets a preset acceleration strategy, transmitting the requirement of the acceleration attribute to the Modem through the AP;

and sending a random data packet to a base station through the Modem based on the requirement of the acceleration attribute.

It should be noted that the accelerated attributes of APP include, but are not limited to, red packet preemption, multi-block preemption, takeout order preemption, drop order preemption, etc., and the data flow of these accelerated attributes is bursty, i.e., there is data transmission for a period of time, and there may be no data transmission for the next period of time. Generally, when there is no data transmission, the network side (e.g. a base station, etc.) releases the RRC connection with the mobile terminal, so that the mobile terminal is in an idle state; however, these acceleration attributes need to have higher real-time performance, and it is desirable that the mobile terminal is in a traffic state more, which can save the transmission delay caused by the RRC re-establishment procedure; when detecting that the operating state meets the preset acceleration strategy, that is, the APP has the requirement of the acceleration attribute, the application processor AP of the mobile terminal transmits the requirement of the acceleration attribute to the Modem, and then the Modem transmits a random data packet to the base station to maintain the RRC connection, thereby avoiding transmission delay caused by the RRC reestablishment process.

It should be noted that the random Data Packet sent by the Modem in the Packet Data Convergence Protocol (PDCP) layer is mainly used to maintain the RRC connection between the mobile terminal and the base station, so that the mobile terminal is in a service state. Referring to fig. 3, which shows a schematic diagram of a composition structure of a legal IP packet frame, it can be seen from fig. 3 that the Data portion should be a normal IP packet according to the protocol, but in the embodiment of the present invention, the random packet is an illegal IP packet, such as a 1byte packet; in this way, the random data packet can be discarded directly by the base station after being received by the base station, and the random data packet does not pass through the charging unit, that is, the transmission of the random data packet does not generate charging.

For the technical solution shown in fig. 2, in a possible implementation manner, before the sending the random data packet to the base station, the method further includes:

sending an RRC connection establishment request message to the base station;

receiving the RRC connection establishment response message returned by the base station;

and sending the RRC connection establishment completion message to the base station to realize the RRC connection with the base station.

For the technical solution shown in fig. 2, in the foregoing implementation, specifically, the sending the random data packet to the base station includes:

transmitting a random data packet to the base station based on the RRC connection when the RRC connection with the base station is achieved.

It should be noted that the RRC connection establishment procedure is specifically as follows: (1) the mobile terminal UE sends an RRC Connection Request message RRC Connection Request through a common control channel CCCH to Request to establish an RRC Connection; (2) the RNC establishes the UE on a dedicated channel according to the reason of the RRC connection request and the system resource state, and allocates a Radio Network Temporary Identity (RNTI), Radio resources and other resources (L1, L2 resources); (3) RNC sends Radio Link Setup Request message to NodeB to Request NodeB to distribute specific Radio Link resource needed by RRC connection; (4) after the NodeB resource is successfully prepared, responding to a Radio Link Setup Response message to the RNC; (5) RNC uses ALCAP protocol to establish Iub interface user surface transmission load and completes the synchronization process between RNC and NodeB; (6) the RNC sends an RRC Connection Setup message RRC Connection Setup to the UE through a downlink CCCH, wherein the message comprises special channel information distributed by the RNC; (7) after the UE confirms that the RRC Connection is successfully established, an RRC Connection Setup Complete message RRC Connection Setup Complete is sent to the RNC in the just-established uplink DCCH channel; it indicates that the RRC connection setup procedure is finished. The mobile terminal may start sending random data packets to the base station based on the established RRC connection after the RRC connection establishment procedure is ended, i.e. after the RRC connection with the base station is achieved.

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

transmitting the random data packet to the base station in a periodic transmission mode; the periodic transmission mode is to transmit at preset time intervals.

It should be noted that, in order to maintain the RRC connection with the base station, the preset time interval needs to be smaller than a preset time threshold. The preset time interval refers to an interval duration for the mobile terminal to send a random data packet to the base station, and the preset time threshold refers to a maximum interval duration which is preset by the mobile terminal to maintain RRC connection with the base station and is allowed by no data transmission, for example, the preset time interval may be set to 8 seconds or 10 seconds, and the preset time threshold may be set to 15 seconds, which is not specifically limited in this embodiment of the present invention. For example, assume that the preset time interval is 10s and the preset time threshold is 15 s, that is, in the PDCP layer, the mobile terminal sends a random data packet to the base station every 10 s; since the time interval is smaller than the preset time threshold, the random data packet is periodically transmitted 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 traffic state.

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

disconnecting the RRC connection with the base station based on a preset time period.

For the technical solution shown in fig. 2, in the foregoing implementation, specifically, the disconnecting the RRC connection with the base station based on a preset time period includes:

starting timing at the first sending time of the random data packet based on a pre-configured timeout timer; the preset duration of the timeout timer represents the duration of the preset time period;

stopping sending the random data packet to the base station at the overtime time timed by the overtime timer;

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

disconnecting the RRC connection with the base station based on the response to the RRC connection release message.

It should be noted that, in order to reduce the transmission delay caused by the RRC connection reestablishment process, the mobile terminal may further configure the random data packet transmission period interval and the corresponding value of the timeout Timer provided by the application processor. Wherein, the corresponding value of interval refers to the preset time interval, which is convenient for the periodic transmission of the random data packet; the corresponding value of the Timer refers to the preset time period, which is convenient for deciding whether to stop sending the random data packet, so that the waste of wireless resources can be avoided. For example, assuming that the Timer is configured to be 4 minutes and the interval is configured to be 10 seconds, when the mobile terminal achieves RRC connection with the base station, the mobile terminal starts to transmit random data packets, and the Timer starts to count time, within 4 minutes, the mobile terminal may always transmit random data packets to the base station at time intervals of 10s, so as to maintain the mobile terminal in a traffic state; however, when the Timer counts for 4 minutes, the mobile terminal stops sending the random data packet to the base station at the overtime of the Timer; when the mobile terminal stops sending the random data packet for a time length so that the base station side considers that no data is transmitted in the time length, the base station releases the RRC connection and sends an RRC connection release message to the mobile terminal, and the RRC connection with the base station is disconnected based on the response of the mobile terminal to the RRC connection release message, so that the mobile terminal is converted from a service state to an idle state.

It should be further noted that, when the mobile terminal detects that the operating state of the third-party application satisfies the preset acceleration policy again, the mobile terminal sends the random data packet to the base station again to maintain the RRC connection with the base station; therefore, the mobile terminal is in a service state more, the RRC connection reestablishment process is saved, and the real-time performance of data transmission is improved.

The embodiment provides a radio resource control connection method, which is applied to a mobile terminal and detects the running state of a third-party application; wherein the running state is used for representing the running condition of the third-party application; when the running state meets a preset acceleration strategy, sending a random data packet to a base station; the random data packet is a non-legal Internet Protocol (IP) data packet which is sent to the base station at a Packet Data Convergence Protocol (PDCP) layer; maintaining a radio resource control, RRC, connection with the base station based on the base station's response to the random data packet; the mobile terminal can be maintained in a service state more, and the RRC connection reconstruction process is saved, so that the transmission delay of data from the mobile terminal to an air interface is reduced, the real-time performance of data transmission is improved, and the use performance of the mobile terminal is also improved.

Example two

Referring to fig. 4, it shows another radio resource control connection method provided in an embodiment of the present invention, which is applied to a base station, and the method may include:

s401: receiving a random data packet sent by a mobile terminal; wherein, the random data packet is a non-legal IP data packet sent by the mobile terminal on a packet data convergence protocol PDCP layer;

s402: maintaining a radio resource control, RRC, connection with the mobile terminal based on the response to the random data packet.

Based on the technical scheme shown in fig. 4, the method is applied to a base station, and receives a random data packet sent by a mobile terminal; wherein, the random data packet is a non-legal IP data packet sent by the mobile terminal on a packet data convergence protocol PDCP layer; maintaining a radio resource control, RRC, connection with the mobile terminal based on the response to the random data packet; the mobile terminal can be maintained in a service state more, and the RRC connection reestablishment process is saved, so that the transmission delay of data from the mobile terminal to an air interface is reduced, and the real-time performance of data transmission is improved.

For the technical solution shown in fig. 4, in a possible implementation manner, after receiving the random data packet sent by the mobile terminal, the method further includes:

analyzing the received random data packet;

and if the analysis fails, discarding the random data packet.

It should be noted that, in the embodiment of the present invention, the random packet is an illegal IP packet, such as a 1byte packet; it is only used to maintain the RRC connection between the mobile terminal and the base station. Therefore, after the random data packet is received by the base station, the base station can analyze the random data packet, if the analysis fails, the random data packet can be directly discarded by the base station, and the random data packet does not pass through the charging unit, that is, the transmission of the random data packet does not generate charging.

For the technical solution shown in fig. 4, in a possible implementation manner, before the receiving a random data packet sent by a mobile terminal, the method further includes:

receiving an RRC connection establishment request message sent by the mobile terminal;

returning the RRC connection establishment response message to the mobile terminal;

and receiving the RRC connection establishment completion message sent by the mobile terminal to realize the RRC connection with the mobile terminal.

For the technical solution shown in fig. 4, in the foregoing implementation, specifically, the receiving a random data packet sent by a mobile terminal specifically includes:

and receiving a random data packet sent by the mobile terminal based on the RRC connection when the RRC connection with the mobile terminal is realized.

It should be noted that, the details of the RRC connection establishment are described in the foregoing first embodiment, and are not described in detail here. After the RRC connection establishment procedure is ended, i.e., after the RRC connection with the mobile terminal is achieved, the base station may start receiving random data packets transmitted by the mobile terminal based on the established RRC connection.

For the technical solution shown in fig. 4, in a possible implementation manner, after the maintaining the radio resource control RRC connection with the mobile terminal, the method further includes:

and if the time length of not receiving the random data packet meets a preset time threshold, disconnecting the RRC connection with the mobile terminal.

For the technical solution shown in fig. 4, in the foregoing implementation manner, specifically, the disconnecting the RRC connection with the mobile terminal if the duration of not receiving the random data packet satisfies a preset time threshold specifically includes:

if the time length for not receiving the random data packet meets a preset time threshold, releasing the RRC connection, and stopping receiving the random data packet;

transmitting the RRC connection release message to the mobile terminal;

disconnecting the RRC connection with the mobile terminal based on a response of the mobile terminal to the RRC connection release message.

It should be noted that the preset time threshold refers to a maximum interval duration that is preset by the mobile terminal to maintain the RRC connection with the base station and no data transmission is allowed. If the preset time threshold is set to 15 seconds, the time length for which the base station does not receive the random data packet reaches 15 seconds, that is, the time length for which the base station does not receive the random data packet meets the preset time threshold, at this moment, the base station releases the RRC connection, stops receiving the random data packet, and sends an RRC connection release message to the mobile terminal; and based on the response of the mobile terminal to the RRC connection release message, further disconnecting the RRC connection with the mobile terminal, so that the mobile terminal is enabled to be changed from the service state to the idle state.

The embodiment provides a radio resource control connection method, which is applied to a base station and used for receiving a random data packet sent by a mobile terminal; wherein, the random data packet is a non-legal IP data packet sent by the mobile terminal on a packet data convergence protocol PDCP layer; maintaining a radio resource control, RRC, connection with the mobile terminal based on the response to the random data packet; the mobile terminal can be maintained in a service state more, and the RRC connection reestablishment process is saved, so that the transmission delay of data from the mobile terminal to an air interface is reduced, and the real-time performance of data transmission is improved.

EXAMPLE III

Based on the same inventive concept of the foregoing embodiment, referring to fig. 5, it shows a detailed flow of a radio resource control connection method provided in the embodiment of the present invention, and an exemplary scenario of the method may refer to fig. 1A, where a third-party application APP takes red packet scrambling in WeChat application as an example, based on the schematic diagram of the wireless communication system architecture shown in fig. 1A, the detailed flow may include:

s501: the mobile terminal detects the running state of the third-party application; wherein the running state is used for representing the running condition of the third-party application;

s502: when the running state meets a preset acceleration strategy, the mobile terminal transmits the requirement of the acceleration attribute to a Modem Modem through an 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 in the running state and the wechat application starts to rob the red packet, since the rob red packet belongs to the acceleration attribute, that is, the running state of the mobile terminal satisfies the preset acceleration policy, at this time, the mobile terminal 104 transmits the requirement of the acceleration attribute to the Modem via 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 a base station;

s506: realizing RRC connection between the base station and the mobile terminal;

for example, taking the architecture of the wireless communication system shown in fig. 1A as an example, in order to implement RRC connection between the mobile terminal 104 and the base station 101, first the mobile terminal 104 needs to send an RRC connection establishment request message to the base station 101, and then the base station 101 returns an RRC connection establishment response message to the mobile terminal 104 based on the received RRC connection establishment request message; the mobile terminal 104 establishes the RRC connection based on the received RRC connection establishment response message, then the mobile terminal 104 sends an RRC connection establishment completion message to the base station 101, and finally the base station 101 realizes 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, mobile terminal 104 may transmit data to base station 101.

S507: when the RRC connection with the mobile terminal is realized, the overtime timer configured by the mobile terminal starts timing, and simultaneously the mobile terminal sends a random data packet to the base station in a periodic sending mode through the Modem;

s508: a base station receives a random data packet sent by a mobile terminal;

s509: the base station analyzes 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, still taking the wireless communication system architecture shown in fig. 1A as an example, in combination with the above example, when implementing RRC connection between the base station 101 and the mobile terminal 104, the timeout timer configured in the mobile terminal 104 starts and starts to count time, and the mobile terminal 104 sends the random data packet to the base station 101 in the periodic sending mode through the Modem; assuming that the timeout timer configured in the mobile terminal 104 is 4 minutes and the transmission period of the random data packet is 10 seconds, the mobile terminal 104 transmits the random data packet at 10-second intervals within 4 minutes, and the base station 101 receives the random data packet; after receiving the random data packet, the base station 101 performs parsing, and since the random data packet is an illegal IP data packet, the parsing is failed, and at this time, the base station 101 directly discards the random data packet, and the random data packet does not pass through 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 maintained in a service state more, the RRC connection reestablishment process is saved, the transmission delay of data from the mobile terminal to the air interface is reduced, and the real-time performance of data transmission is improved.

S512: at the overtime moment timed by the overtime timer, the mobile terminal stops sending the random data packet to the base station;

s513: if the time length of the base station not receiving 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 a mobile terminal;

s515: disconnecting the RRC connection of the base station and the mobile terminal based on a response of the mobile terminal to the RRC connection release message.

For example, still taking the wireless communication system architecture shown in fig. 1A as an example, in combination with the above example, assuming that the preset time threshold is 15 seconds, since the timeout timer configured in the mobile terminal 104 is 4 minutes, within 4 minutes, the mobile terminal 104 sends random data packets to the base station 101 at intervals of 10 seconds; when the time of the timeout timer reaches 4 minutes, that is, at the timeout moment of the time of the timeout timer, the mobile terminal 104 stops sending the random data packet to the base station 101; at this time, the base station 101 does not receive the random data packet, when the time length for which the base station 101 does not receive the random data packet satisfies 15 seconds, the base station 101 defaults that no data transmission exists in the time length, the base station 101 releases the RRC connection, and stops receiving the random data packet; meanwhile, the base station 101 sends an RRC connection release message to the mobile terminal 104; the mobile terminal 104 then responds based on the received RRC connection release message such that the RRC connection between the base station 101 and the mobile terminal 104 is broken, thereby transitioning the mobile terminal from the traffic state to the idle state.

Through the embodiments, the specific implementation of the foregoing embodiments is elaborated in detail, and it can be seen that through the technical scheme of the foregoing embodiments, the mobile terminal can be maintained in a service state more, and an RRC connection reestablishment process is saved, so that transmission delay of data from the mobile terminal to an air interface is reduced, real-time performance of data transmission is improved, and usability of the mobile terminal is also improved.
