As shown in FIG. 1, the method is applied to a terminal, and the terminal includes a data subscriber identity module (SIM) card and For non-data SIM cards, the method may include:

S101. Determine an occupation time of radio frequency resources occupied by a non-data SIM card.

The RRC state maintenance method provided by the embodiment of the present application is applicable to a scenario where the non-data SIM card of the terminal occupies radio frequency (RF) resources when the data SIM card of the terminal is in the RRC connected state.

The above terminal can be any device with communication and storage functions, such as: tablet computer, mobile phone, e-reader, remote control, personal computer (PC), personal digital assistant, notebook computer, in-vehicle equipment, network TV, Wearable devices and other equipment.

In the embodiment of the present application, the terminal is provided with multiple SIM card slots for installing multiple SIM cards. The SIM card types of the multiple SIM cards include data SIM cards and non-data SIM cards. The application data SIM card needs to be used for services Data flow, services implemented using non-data SIM cards do not need to use data flow.

The terminal in the embodiment of the application is a dual SIM dual standby (Dual SIM dual Standby, DSDS) terminal.

Optionally, the services corresponding to the non-data SIM card include voice services, short message services, call services, etc., which are specifically selected according to actual conditions, and the embodiments of the present application do not make specific limitations.

Optionally, the services corresponding to the data SIM card include online video viewing services, online audio playback services, instant messaging services, etc. The specific selection is based on actual conditions, and the embodiment of the present application does not make specific limitations.

In an optional embodiment, when the data SIM card of the terminal is in the RRC connection state, when the non-data SIM card of the terminal responds to the service request, the terminal determines that the non-data SIM card occupies radio frequency resources. At this time, The terminal obtains the service and service type of the radio frequency resource occupied by the non-data SIM card; and determines the estimated service time corresponding to the service type. After that, the terminal compares the estimated service time with the first time threshold. When the estimated service time is less than the first time threshold, At the time threshold, when the terminal determines that the non-data SIM card ends service processing and releases radio frequency resources, the terminal obtains the service processing time for the non-data SIM card to process the service request, and uses the service processing time to determine the occupied time.

In the embodiment of this application, the terminal determines the estimated service time corresponding to different service types based on the historical service and the actual time occupied, and obtains the correspondence between the service type and the estimated service time. When the terminal obtains that the non-data SIM card occupies the radio frequency In the case of the service and service type of the resource, the estimated service time corresponding to the service type is searched from the corresponding relationship between the terminal service type and the estimated service time.

Exemplarily, when the terminal uses the data traffic of card 1 (data SIM card) to watch the video, card 1 is in the RRC connection state, when card 2 (non-data SIM card) receives the short message and uses card 2 to reply to the message During the short message, the card 2 preempts the RF resources. At this time, the terminal determines the estimated service time corresponding to the short message service.

In another optional embodiment, when the terminal determines that the non-data SIM card occupies the radio frequency resources, the terminal monitors the time that the non-data SIM card occupies the radio frequency resources to process the service in real time. When the terminal determines that the non-data SIM card releases the radio frequency In the case of resources, the terminal obtains the service processing time from when the radio frequency resource is occupied by the non-data SIM card to when the radio frequency resource is released by the non-data SIM card, and determines the service processing time as the occupied time.

It should be noted that the timing of obtaining the service processing time at the terminal in the embodiment of the application may be when the terminal determines that the estimated service time is less than the first time threshold, or the terminal does not need to obtain the estimated service time and directly counts non-data The time between when the SIM card occupies the radio frequency resource and when the non-data SIM card releases the radio frequency resource is specifically selected according to actual conditions, and is not specifically limited in the embodiment of the present application.

It should be noted that, in the embodiment of this application, the terminal can use the estimated service time as the occupancy time of the radio frequency resource occupied by the non-data SIM card, or the service processing time as the occupancy time of the radio frequency resource occupied by the non-data SIM card. The estimated service time and service processing time can be used to determine the occupancy time of the radio frequency resource occupied by the non-data SIM card. Among them, the estimated service time and service processing time are used to determine the occupancy time of the radio frequency resource occupied by the non-data SIM card. Obtain the estimated business time. When it is judged that the estimated business time is less than the first time threshold, the business processing time is acquired and the business processing time is determined as the occupancy time. The specific selection is based on the actual situation. The embodiment of this application does not make specific details limited.

S102: Determine the synchronization between the RRC state of the data SIM card and the RRC state of the network according to the occupied time and the preset time threshold.

The terminal is preset with a preset time threshold. After the terminal determines the occupancy time of the radio frequency resource occupied by the non-data SIM card, the terminal will compare the occupancy time with the preset time threshold, and determine the RRC of the data SIM card based on the comparison result The synchronization between the state and the RRC state of the network.

In the embodiment of the present application, the preset time threshold includes a first time threshold and a second time threshold, where the first time threshold is greater than the second time threshold, that is, the first time threshold is the upper limit of the time preset by the terminal, and the second time threshold The lower limit of the time preset for the terminal.

In the embodiment of this application, after the terminal obtains the estimated service time, the terminal compares the estimated service time with the first time threshold. When the estimated service time is greater than the first time threshold, it indicates that the non-data SIM card responds to the service The response time is too long. At this time, the terminal directly determines that the synchronization situation is that the RRC state of the data SIM card is not synchronized with the RRC state of the network; when the estimated service time is less than the first time threshold, the terminal is based on the service processing time and preset The time threshold determines the synchronization between the RRC state of the data SIM card and the RRC state of the network.

In the embodiment of this application, when the terminal obtains the service processing time, the terminal determines the synchronization between the RRC status of the data SIM card and the RRC status of the network according to the service processing time and the preset time threshold: The business processing time is compared with the first time threshold and the second time threshold, respectively, corresponding to three comparison results:

When the service processing time is less than the second time threshold, the terminal determines that the synchronization situation is that the RRC state of the data SIM card is synchronized with the RRC state of the network;

When the service processing time is greater than the first time threshold, the terminal determines that the synchronization situation is that the RRC state of the data SIM card is not synchronized with the RRC state of the network;

When the service processing time is in the first time interval, the terminal uses the data SIM card to communicate with the network, and determines the synchronization between the RRC state of the data SIM card and the RRC state of the network according to the communication result. The first time interval is the second The time interval between the time threshold and the first time threshold.

In the embodiment of this application, the terminal uses a data SIM card to send a communication request to the network; when receiving a request response from the network in response to the communication request, the terminal determines that the synchronization situation is that the RRC state of the data SIM card is synchronized with the RRC state of the network ; When the request response returned by the network is not received, the terminal determines that the synchronization situation is that the RRC state of the data SIM card is not synchronized with the RRC state of the network.

Exemplarily, the data SIM card of the terminal triggers (Signaling Radio Bearers2, SRB2) RLC Polling (communication request), when the terminal receives the HARQ ACK response from the network side in response to the RLC Polling or the terminal receives the RLC status sent by the network side In the report, the terminal judges that the network has not released the RRC connection. The HARQ ACK response or RLC status report is the response to the request in this application. At this time, the terminal determines that the RRC status of the data SIM card is synchronized with the RRC status of the network; When the terminal does not receive the HARQ ACK response from the network side in response to the RLC Polling or the terminal does not receive the RLC status report sent by the network side, the terminal determines that the network has released the RRC connection. At this time, the terminal determines the RRC of the data SIM card The state is not synchronized with the RRC state of the network.

It should be noted that the terminal only uses the estimated service time and the preset time threshold to determine the synchronization between the RRC status of the data SIM card and the RRC status of the network, and the terminal uses the service processing time and preset time threshold. The process of determining the synchronization between the RRC state of the data SIM card and the RRC state of the network is consistent, and will not be repeated here.

S103: Control the RRC connection of the data SIM card according to the synchronization situation.

After the terminal determines the synchronization situation between the RRC state of the data SIM card and the RRC state of the network, the terminal controls the RRC connection of the data SIM card according to the synchronization situation.

In an optional embodiment, when the terminal determines that the synchronization situation is that the RRC state of the data SIM card is not synchronized with the RRC state of the network according to the service processing time and the preset time threshold, the terminal releases the RRC connection of the data SIM card ; And re-establish the RRC connection between the data SIM card and the network.

In another optional embodiment, when the terminal determines that the synchronization situation is that the RRC state of the data SIM card is not synchronized with the RRC state of the network according to the estimated service time and the first time threshold, the terminal releases the data SIM card RRC connects and waits for the non-data SIM card to release radio frequency resources. When the terminal determines that the non-data SIM card releases radio frequency resources, the terminal re-establishes the RRC connection between the data SIM card and the network.

Specifically, the terminal uses the service request (service request) process to re-establish the RRC connection between the data SIM card and the network; or the terminal initiates the Evolved Packet System (EPS) mobility process (EPS Mobility Management, EMM) process (Tracking Area Update (TAU)) communicates with the network, and then restores the connection between the signaling plane and the data plane.

In the embodiment of the present application, when the terminal determines that the synchronization situation is that the RRC state of the data SIM card is synchronized with the RRC state of the network, the terminal maintains the RRC connection of the data SIM card.

Exemplarily, as shown in Figure 2, it is the process in which the terminal uses the estimated service time and service processing time to jointly implement the RRC state maintenance. Specifically,

1. When the data SIM card is in the RRC connection state, the non-data SIM card preempts RF resources;

2. The terminal estimates the estimated business time for the non-data SIM card to seize the RF resources according to the type of business realized by the non-data SIM card;

3. The terminal compares the estimated business time with the first time threshold;

4. When the estimated service time is greater than the first time threshold, the terminal releases the RRC connection state of the data SIM card;

5. Until the non-data SIM card releases the RF resources, the terminal re-establishes the RRC connection between the data SIM card and the network;

6. When the estimated business time is less than the first time threshold, the terminal monitors whether the non-data SIM card releases RF resources;

7. When the non-data SIM card releases RF resources, the terminal obtains the service processing time of the non-data SIM card;

8. The terminal compares the service processing time with the first time threshold and the second time threshold respectively;

9. When the business processing time is less than the second time threshold, execute 15;

10. When the business processing time is greater than the first time threshold, execute 16 and 17;

11. When the service processing time is in the time interval between the second time threshold and the first time threshold, use the data SIM card to initiate RLC Polling;

12. The terminal judges whether it receives an RLC status report or HARQ ACK response;

13. When the terminal receives the RLC status report or HARQ ACK response, execute 15;

14. When the terminal does not receive the RLC status report or HARQ ACK response, execute 16 and 17;

15. The terminal maintains the RRC connection state of the data SIM card;

16. The terminal releases the RRC connection state of the data SIM card;

17. The terminal re-establishes the RRC connection between the data SIM card and the network.

Exemplarily, as shown in Figure 3, it is a process in which the terminal uses service processing time to implement RRC state maintenance. Specifically,

1. When the data SIM card is in the RRC connection state, the non-data SIM card preempts RF resources;

2. The service processing time for the terminal to obtain the non-data SIM card;

3. The terminal compares the service processing time with the first time threshold and the second time threshold respectively;

4. When the business processing time is less than the second time threshold, execute 10;

5. When the business processing time is greater than the first time threshold, execute 11 and 12;

6. When the service processing time is in the time interval between the second time threshold and the first time threshold, use the data SIM card to initiate RLC Polling;

7. The terminal judges whether it receives an RLC status report or HARQ ACK response;

8. When the terminal receives the RLC status report or HARQ ACK response, execute 10;

9. When the terminal does not receive the RLC status report or HARQ ACK response, execute 11 and 12;

10. The terminal maintains the RRC connection state of the data SIM card;

11. The terminal releases the RRC connection state of the data SIM card;

12. The terminal re-establishes the RRC connection between the data SIM card and the network.

It is understandable that the terminal sets a preset time threshold, and compares the occupancy time of radio frequency resources occupied by the non-data SIM card with the preset time threshold to determine the synchronization between the RRC state of the data SIM card and the RRC state of the network , The terminal can control the data SIM card to maintain the RRC connection or release the RRC connection according to the synchronization situation, reducing the probability of re-establishing the RRC connection, thereby reducing the time delay for restoring the RRC connection of the data SIM card.
