Background
Currently, for a Dual Sim Dual Standby (DSDS) terminal device, there is only one set of radio resources (e.g. antenna and rf path), and two Sim cards need to share one set of radio resources. When the SIM card 1 performs data service transmission, if the SIM card 2 establishes a communication connection with a network device, the current SIM card 1 cannot use wireless transceiving resources, and the service of the SIM card 1 is interrupted at this time. However, there are many reasons for triggering the SIM2 card to establish a communication connection with the network device, and especially, some periodic traffic transmission events may trigger the SIM2 card to establish a communication connection with the network device according to a certain time period. Moreover, the time periods of various periodic service transmission events are different from each other, and therefore, the SIM2 needs to establish communication connection with the network device for multiple times within a period of time, so that service transmission of the SIM card 1 is interrupted for multiple times, which causes problems such as stuttering of the service transmission of the SIM card 1.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic diagram of a system architecture according to an embodiment of the present application.
As shown in fig. 1, communication system 100 may include a terminal device 110 and a network device 120. Network device 120 may communicate with terminal device 110 over the air. Multi-service transport is supported between terminal device 110 and network device 120.

In the current dual-card dual-standby scenario, because two SIM cards share one set of wireless transceiving resources, when the SIM card 1 performs a low-latency sensitive service (for example, game, live broadcast), if the SIM card 2 frequently establishes a communication connection with a network device for service transmission, the low-latency sensitive service of the SIM card 1 is frequently interrupted, which causes a problem of card pause or latency, and affects user experience.
Based on this, an embodiment of the present application provides a service transmission method, which is applied to a terminal device supporting at least two SIM cards, where the at least two SIM cards share a set of wireless transceiving resources. Specifically, the terminal device may determine the target time parameter based on time periods corresponding to a plurality of first events, where the first event is an event that the first SIM card needs to periodically occupy the wireless transceiving resource for service transmission, and the first SIM card is any one of the at least two SIM cards; further, the terminal device transmits a service corresponding to at least one target event when detecting that the first SIM card establishes a communication connection with the network device, where the at least one target event includes a first event satisfying a first condition, and the first condition includes that a remaining duration of next service transmission is less than or equal to the target time parameter. It can be seen that the terminal device can determine a target time parameter according to time periods corresponding to the plurality of first events respectively, and unify the disordered time periods. In addition, under the condition that the terminal equipment detects that the first SIM card is in communication connection with the network equipment, the terminal equipment transmits one or more services corresponding to the first events of which the remaining time is less than or equal to the target time parameter, namely, the terminal equipment simultaneously transmits the services corresponding to the one or more first events needing service transmission recently during the communication connection, so that the number of times of establishing the communication connection between the first SIM card and the network equipment is reduced, the number of times of interrupting service transmission of other SIM cards in the terminal equipment is reduced, and the smoothness of service transmission of other SIM cards is improved.
In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below with specific embodiments. The above related art can be arbitrarily combined with the technical solutions of the embodiments of the present application as alternatives, which all belong to the scope of protection of the embodiments of the present application. The embodiment of the present application includes at least part of the following contents.
An embodiment of the present application provides a service transmission method, which may be applied to the terminal device shown in fig. 1. The terminal device may support at least two identity recognition SIM cards, where the terminal device may support two SIM cards, and the terminal device may also support three or more SIM cards, where the embodiments of the present application are not specifically limited herein.
Fig. 2 is a schematic flow diagram of a service transmission method provided in an embodiment of the present application, and referring to fig. 2, the service transmission method may include:
step 210, the terminal device determines a target time parameter based on the time periods corresponding to the plurality of first events, respectively.
The first event is an event that the first SIM card needs to periodically occupy wireless transceiving resources for service transmission; the first SIM is any one of at least two SIM cards supported by the terminal device.
In the embodiment of the application, because at least two SIM cards supported by the terminal device share one set of wireless transceiving resources, the terminal device and the network device can only establish communication connection through one of the at least two SIM cards at the same time. The communication connection may be a Radio Resource Control (RRC) connection.
That is, the terminal device does not support the simultaneous use of two or more SIM cards, and the terminal device can use only one of the SIM cards at a time. When a first SIM card of a terminal device occupies radio transceiving resources to establish RRC connection with a network device, other SIM cards need to first release the RRC connection with the network device.
Optionally, the first SIM card may be any one of at least two SIM cards supported by the terminal device, for example, the first SIM card may be a primary SIM card of the at least two SIM cards, and the first SIM card may also be a secondary SIM card of the at least two SIM cards, which is not limited in this embodiment of the present application.
It should be understood that there are many first events that trigger the first SIM card of the terminal device to actively occupy the radio resource for establishing the RRC connection with the network device, for example, a Tracking Area Update (TAU) event, an Internet Protocol (IP) address Update event, an IP Multimedia System (IMS) re-registration event, and the like. The TAU event needs the terminal device to report the current tracking area code of the terminal device to the network device according to a time period (for example, 54 minutes), the IP address update event needs the terminal device to report the current IP address to the network device according to a time period (for example, 50 minutes), and the IMS re-registration needs to report the binding relationship between the public identifier of the user and the IP address and other user information to the network device according to a time period.
In practical applications, the first events triggering the first SIM card to actively occupy the radio resource and establish the RRC connection with the network device are independent from each other, and the time periods corresponding to the first events are different from each other, which requires the first SIM card to frequently establish the RRC connection with the network device to complete different service transmissions. Therefore, when the second SIM card of the terminal device performs persistent service transmission, the terminal device needs to frequently release the RRC connection between the second SIM card and the network device, so as to ensure that the first SIM card can establish the RRC connection with the network device, thereby causing interruption and suspension of the transmission of the second SIM service.
Based on this, the terminal device in the embodiment of the present application may obtain time periods corresponding to the plurality of first events, and determine one target time parameter based on the plurality of time periods corresponding to the plurality of first events, so as to align the plurality of disordered time periods of the first events. For example, the terminal device may use any one of a plurality of time periods corresponding to the plurality of first events as the target time parameter, the terminal device may also use an average of the plurality of time periods corresponding to the plurality of first events as the target time parameter, and the terminal device may also use a minimum of the plurality of time periods corresponding to the plurality of first events as the target time parameter, which is not limited in this embodiment of the application.
Step 220, the terminal device transmits a service corresponding to at least one target event when detecting that the first SIM card establishes a communication connection with the network device.
The at least one target event comprises a first event meeting a first condition in the plurality of first events, and the first condition comprises that the remaining time length for carrying out next service transmission is less than or equal to the target time parameter.
It can be understood that the terminal device may continuously monitor a connection state of the first SIM card and the network device, and when the terminal device detects that the first SIM card establishes a communication connection with the network device, the terminal device may check a remaining time duration of next service transmission performed by each first event of the plurality of first events, and perform service transmission in advance on the first event (that is, the target event) whose remaining time duration is less than or equal to the target time parameter when the first SIM card is connected with the network device this time.
That is to say, when the first SIM card is in RRC connection with the network device, the terminal device may transmit one or more services corresponding to a first event that needs to execute service transmission recently during the current communication connection, so as to reduce the frequency of establishing RRC connection between the terminal device and the network device through the first SIM card, thereby reducing the impact on the services of other SIM cards and avoiding the problem of traffic congestion of other SIM cards.
In summary, in the service transmission method provided in the embodiment of the present application, the terminal device may determine a target time parameter according to time periods corresponding to the plurality of first events, and unify the disordered time periods. In addition, the terminal device transmits one or more services corresponding to the first event with the remaining duration less than or equal to the target time parameter when detecting that the first SIM card is in communication connection with the network device, that is, the terminal device simultaneously transmits the services corresponding to the one or more first events which need to be subjected to service transmission recently during the communication connection, so that the number of times of establishing communication connection between the first SIM card and the network device is reduced, thereby reducing the number of times of interrupting service transmission of other SIM cards in the terminal device, and improving the smoothness of service transmission of other SIM cards.
In an embodiment of the present application, referring to fig. 3, before the terminal device determines the target time parameter based on time periods corresponding to a plurality of first events in step 210, the service transmission method provided in the embodiment of the present application may further include the following steps:
step 200, the terminal device determines an event meeting a second condition as a first event; the second condition includes: and actively triggering the first SIM card to establish communication connection with the network equipment according to the time period.
In this embodiment of the application, before the terminal device performs service transmission, all events of the first SIM card that need to complete service transmission may be traversed, and an event that satisfies the second condition among the events is determined as the first event. The second condition may be that the terminal device is required to actively trigger the first SIM card to establish an RRC connection with the network device for service transmission, where the service is a periodic service.
That is, the terminal device may take, as the first event, an event that includes the following two features in all events that need to be completed by the first SIM card: the terminal device is required to actively trigger the first SIM card to establish RRC connection with the network device for service transmission, and the service is a periodic service. Furthermore, the terminal device may determine the target time parameter according to the obtained time periods corresponding to the plurality of first events, respectively.
Optionally, the plurality of first events may include at least two of the following events:
an IMS re-registration event for the first SIM card;
a TAU event of the first SIM card;
an IP address update event for the first SIM card.
It should be understood that the TAU event of the first SIM card requires the terminal device to establish an RRC connection with the network device through the first SIM card according to a time period (e.g. 54 minutes), and report the current tracking area code of the terminal device to the network device through the RRC connection. The first SIM card IP address update event requires the terminal device to establish an RRC connection with the network device through the first SIM card according to a time period (e.g., 50 minutes), and report the current IP address to the network device through the RRC connection. An IMS re-registration event of the first SIM card requires that the terminal device establish an RRC connection with the network device through the first SIM card according to a time period, and report the binding relationship between the public identifier of the user and the IP address, and other user information to the network device through the RRC connection.
In summary, in the service transmission method provided in the embodiment of the present application, the terminal device may actively determine, according to the second condition, a plurality of first events from the plurality of events, and determine the target time parameter based on the time periods of the plurality of first events. Therefore, the terminal device can flexibly determine a plurality of first events according to the events actually executed by the first SIM card, and further realize the alignment of the time periods of the plurality of first events.
In an embodiment of the present application, in step 210, the terminal device determines the target time parameter based on time periods corresponding to the plurality of first events, and may be implemented in the following manner: and the terminal equipment determines the shortest time period in the time periods corresponding to the first events as a target time parameter.
It should be understood that each of the plurality of first events may be a periodic event. That is, each first event may have a time period of a traffic transmission.
Optionally, the time period of each first event may be configured by the network device, or may be agreed between the terminal device and the network device (e.g., protocol specification). The embodiments of the present application are not limited thereto.
In the embodiment of the application, the terminal device may obtain time periods corresponding to the plurality of first events, select the shortest time period from the time periods corresponding to the plurality of first events, and use the selected shortest time period as the target time parameter T. When the terminal device establishes a communication connection with the network device through the first SIM card, the terminal device may transmit a service corresponding to a first event (i.e., a target event) whose remaining time is less than or equal to the target time parameter T in advance through the communication connection established this time. It can be understood that the terminal device may unify the time periods of the plurality of first events into the shortest time period, that is, the terminal device may perform traffic transmission on one or more first events that need to perform traffic transmission recently every shortest time period.
Illustratively, the plurality of first events includes a TAU event and an IP address update event of the first SIM card. The TAU event needs the terminal device to report the current tracking area code of the terminal device to the network device every 54 minutes, and if the tracking area code is not reported for more than 54 minutes by the terminal device, the problem of failure in positioning the terminal device and the network device is caused. In addition, an IP address update event requires that the terminal device reports the current IP address to the network device every 50 minutes, and if the terminal device does not report the current IP address for more than 50 minutes, the address cannot be synchronized. The terminal device may use a time period corresponding to the IP address update event, i.e., 50 minutes, as the target time parameter. When the terminal device detects that the first SIM card establishes RRC connection with the network device, it may check the remaining time for the next service transmission of the TAU event and the IP address update event of the first SIM card, and perform service transmission in advance for the event whose remaining time is less than or equal to 50 minutes.
It can be understood that, taking the shortest time period among the time periods corresponding to the plurality of first events as the target time parameter can avoid the problem that the data synchronization between the terminal device and the network device is lost due to the overlong target time parameter, and can also avoid the problem that the service transmission of other SIM cards is suspended due to the frequent establishment of communication connection between the terminal device and the network device for service transmission due to the overlong target time parameter.
In an embodiment of the present application, the terminal device may configure a timer (or referred to as a timer) for each first event, and determine, by using the timer, a remaining duration of next service transmission performed by each first event. For example, after each first event performs one service transmission, the terminal device may reset a timer corresponding to the first event, where a total duration of the timer is a time period corresponding to the current first event. Therefore, when the terminal device detects that the first SIM card establishes a communication connection with the network device, the timer corresponding to each first event may be read, and the remaining duration of the next service transmission performed by each first event is determined according to the timer corresponding to each first event.
Optionally, referring to fig. 4, the service transmission method provided in an embodiment of the present application may further include the following steps:
step 230, the terminal device resets a timer corresponding to each target event based on a time period corresponding to each target event in the at least one target event; the timer is used for determining the remaining time length for next service transmission.
It can be understood that, when the terminal device establishes a communication connection with the network device through the first SIM card in step 220, the service corresponding to the first event (that is, the target event) whose remaining duration for performing the next service transmission is less than or equal to the target time parameter may be transmitted in advance, and after the service corresponding to the target event is transmitted, the next service transmission for the target event may be performed again according to the time period of each target event. That is, the terminal device may reset the timer corresponding to the target event according to the time period corresponding to the target event.
Therefore, in the service transmission method provided in the embodiment of the present application, after the terminal device transmits the service corresponding to the target event in advance, the terminal device actively resets the timer corresponding to the target event, so as to reduce an event that a communication connection is established between the first SIM card and the network device in advance, and reduce the influence on other SIM cards.
Optionally, referring to fig. 5, in the service transmission method provided in an embodiment of the present application, step 210 is performed by the terminal device determining the target time parameter based on time periods corresponding to the plurality of first events, and the method may also be completed in the following manner:
step 2101, the terminal device detects whether a first instruction is received, the first instruction being used to start the dual-card low-delay mode;
step 2102, if the first instruction is received, the terminal device determines a target time parameter based on time periods corresponding to the plurality of first events respectively.
Here, the first instruction is for initiating the dual card low latency mode. In the dual-card low-delay mode, the terminal device may determine a target time parameter based on time periods corresponding to the plurality of first events, align the time periods of the plurality of first events, and transmit services of the plurality of first events based on the target time parameter, so as to reduce the number of times of connection between the first SIM card and the network device, thereby reducing the delay of service transmission of other SIM cards, and avoiding a situation that the service transmission of other SIM cards is suspended.
It can be understood that, after receiving the first instruction, the terminal device starts the dual-card low-latency mode, and in the starting of the dual-card low-latency mode, the terminal device may determine a plurality of first events, determine a target time parameter based on time periods respectively corresponding to the plurality of first events, and perform service transmission based on the target time parameter.
In specific implementation, the terminal device may first determine whether a first instruction is received, determine a target time parameter based on time periods corresponding to a plurality of first events if the first instruction is received, and perform service transmission in advance for a first event (that is, the target event) whose remaining duration is less than or equal to the target time parameter when it is detected that the first SIM card establishes a communication connection with the network device. If the first instruction is not received, whether the first instruction is received or not is continuously detected, and service transmission is carried out according to a mode in the related technology.
The service transmission method provided in the embodiment of the present application is described in detail below with reference to specific examples.
In this example, the terminal device supports two SIM cards, a primary SIM card and a secondary SIM card, respectively. When the primary SIM card performs low-latency high-sensitivity service transmission, the secondary SIM card may perform service transmission according to the steps shown in fig. 6, which specifically includes the following contents.
Step 601, establishing an event list to be optimized.
The terminal device may traverse all events requiring the secondary SIM card to complete service transmission, and add the event satisfying the first condition to the to-be-optimized event list. Here, the first condition specifically includes: an event that the terminal device actively triggers the secondary SIM card to establish RRC connection with the network device is required, and the event is a periodic event.
Here, the event list to be optimized may include a plurality of first events, each of which satisfies the first condition.
Optionally, the terminal device may update the to-be-optimized event list, for example, the terminal device may traverse all events requiring the secondary SIM card to complete service transmission again according to a time period, and redetermine an event satisfying the second condition among the events, so as to update the to-be-optimized time list, or when the terminal device detects that the event requiring the secondary SIM card to complete changes (addition or deletion), the terminal device may traverse all events requiring the secondary SIM card to complete service transmission again, determine an event satisfying the second condition from the events, and implement updating the to-be-optimized event list.
Step 602, detecting whether to start a dual-card low-delay mode.
Here, the terminal device may determine whether it is in the dual card low latency mode by detecting whether a first instruction to turn on the dual card low latency mode is received.
Specifically, if the terminal device receives the first instruction, it is determined that the terminal device starts the dual-card low latency mode, and the terminal device continues to execute step 603. And if the terminal equipment does not receive the first instruction, determining that the terminal equipment does not start the dual-card low-delay mode, and not carrying out subsequent operation on the terminal equipment.
Step 603, obtaining a time period corresponding to each first event in the event list to be optimized, and recording the shortest time period as T.
Step 604, detecting whether an RRC connection is established with the network device through the secondary SIM card.
Specifically, the terminal device may listen to the RRC connected state of the secondary SIM card. If the terminal device establishes RRC connection with the network device through the secondary SIM card, step 605 is executed. And if the terminal equipment does not establish RRC connection with the network equipment through the secondary SIM card, continuously detecting whether the terminal equipment establishes RRC connection with the network equipment through the secondary SIM card.
Step 605, determine whether there is a first event with a remaining duration less than or equal to T in the event list to be optimized.
It can be understood that, when the terminal device establishes the RRC connection with the network device through the secondary SIM card, the remaining duration of the next service transmission for each first event in the to-be-optimized event list is checked. And judging whether a first event with the residual duration less than or equal to T exists in the event list to be optimized, and if the first event with the residual duration less than or equal to T exists, continuing to execute the step 606. If there is no first event with a remaining duration less than or equal to T, then go back to step 604.
Step 606, transmitting the service corresponding to the target event, and resetting the timer of the target event.
Wherein the target event includes a first event with a remaining duration less than or equal to T in step 605. The timer is used for determining the remaining time length for next service transmission.
It can be understood that, when the RRC connection is established with the network device through the secondary SIM card this time, the terminal device may simultaneously perform service transmission on the first event whose remaining duration is less than or equal to T in step 605. That is to say, the secondary SIM card may transmit one or more services corresponding to events that need to perform data synchronization with the network device in the near future in one RRC connection process, and reduce the number of times that the secondary SIM card can establish RRC connection in advance, thereby reducing the number of interruptions to the service of the primary SIM card and avoiding data disconnection.
Therefore, the time period of the periodic service transmission event is aligned, so that the respective independent periodic service transmission events on the secondary SIM card are intensively completed in one RRC establishment process, the problem of blocking caused by interruption of the data service of the main SIM card due to the fact that the secondary SIM card establishes RRC for many times is avoided, and user experience under a low-delay and high-sensitivity scene is improved.
