Referring to fig. 1, an embodiment of the present application provides a communication method, including:
step S10, when the first communication card is used for communication, the communication time length is obtained;
step S20, processing the first PDU conversation of the second communication card according to the conversation time length;
and step S30, after the first communication card finishes the conversation, restoring the data service of the second communication card according to the result of processing the first PDU conversation.
Referring to fig. 2, the present embodiment provides a communication device 200, and the communication device 200 includes an obtaining module 21, a processing module 22, and a recovering module 23. The obtaining module 21 is configured to obtain a call duration when a call is performed using a first communication card; the processing module 22 is configured to process the first PDU session of the second communications card according to the call duration; the recovery module 23 is configured to recover the data service of the second communication card according to the result of processing the first PDU session after the first communication card ends the call.
Referring to fig. 3, an embodiment of the present invention further provides an electronic device 100, where the electronic device 100 may be installed with a plurality of communication cards, where each communication card may be a Subscriber Identity Module (SIM) card, and is used as a carrier for secure storage of user data and Identity authentication for network access. The electronic device 100 further comprises a memory 12, the memory 12 being adapted to store a computer program. The processor 11 is configured to obtain a call duration when a call is performed using the first communication card; and the first PDU session of the second communication card is processed according to the call duration; and the data service recovery module is used for recovering the data service of the second communication card according to the result of processing the first PDU conversation after the first communication card finishes the conversation.
Specifically, the electronic device 100 may be a smart phone, a tablet computer, a smart watch, or other electronic equipment that can be equipped with a communication card for communication. In the embodiment of the present application, the communication card using the mobile data is defined as the default data master card, that is, the default data master card may be switched according to the actual needs and specific behaviors of the user.
For example, in one scenario of the present embodiment, the electronic device 100 used by the user is a smart phone and supports dual-card dual standby. In general, a user accesses a 3GPP network (a mobile communication network based on a 3GPP framework) to use a data service (for example, browse a web page, use a third-party application), where the second communication card is a default data host card, when the user listens to a phone call entered by the first communication card, the first communication card is switched to the default data host card, and after the call is ended, the data service of the second communication card is recovered, and the second communication card is switched to the default data host card again.
Therefore, it can be easily understood that the communication method in the present application is used for quickly recovering the data service on the originally set default data master card in the process of switching the default data master card when the user does not actively switch the default data master card (for example, the non-default data master card suddenly has a call incoming to answer).
Specifically, the configuration scheme of the first communication card and the second communication card in this embodiment may be: the first communication card may be registered in Long Term Evolution (LTE), and the second communication card may be registered in a New Radio interface (5-Generation New Radio, 5G NR) of a fifth Generation mobile communication technology, that is, the second communication card may be a 5G communication card, and the first communication card may be a 4G communication card; of course, the configuration scheme may also be a dual 5G scheme, that is, both the first communication card and the second communication card are configured to support 5G communication.
In step S10, the processor 11 in the electronic device 100 may obtain a call duration of a call using a first communication card, where the first communication card is a default data master card.
In step S20, a PDU (Protocol Data Unit) refers to a Unit for transmitting Data between peer layers in a hierarchical Network structure, and further, a PDU Session (PDU Session) is a new abstract concept provided in a 5G system, which is similar to a PDN Connection (Packet Data Network Connection) in an LTE system, and the PDU Session is used to provide a PDU transmission service between a User Equipment UE (also called a terminal) and a Data Network dn Data Network (Data Network), that is, a Data transmission channel from the terminal to the Data Network is established after the PDU Session is established.
In particular, the PDU session establishment request can only be issued by the user equipment, and in the embodiment of the present application, the user equipment initiating the PDU session establishment request may be the electronic device 100. The PDU session may be triggered when the electronic device 100 is powered on, along with the network registration procedure, or may be triggered by the electronic device 100 alone when accessing a specific service (e.g., clicking on an application).
Then, as mentioned above, the first PDU session in this embodiment refers to a PDU session that is requested to be established from the data network when the electronic device 100 uses data services when the default data master card is the second communication card. After the default data master card is switched to the first communication card, the processor 11 may further process the first PDU session established by the electronic device 100 according to the second communication card according to the call duration obtained in step S10, for example, the first PDU session may be released or retained.
In step S30, after the first PDU session is established, the data network allocates corresponding resources, such as IP address, control plane resources, and user plane resources, to the electronic device 100, at this time, the resources included in the first PDU session may be further processed according to the processing result in step S20, so that the data service of the second communication card is quickly recovered after the second communication card is switched back to the default data master card.
In the communication method, the communication device 200, and the electronic device 100 according to the embodiment of the present application, the first PDU session of the second communication card is processed according to the obtained call duration of the call using the first communication card, and the data service of the second communication card is recovered in different manners according to the processing result, so that when the communication card is switched under an emergency situation of a user, it can be ensured that the speed of recovering the default data master card, that is, the data service of the second communication card, is faster after the switching is completed, thereby improving the user experience.
Referring to fig. 4, in some embodiments, processing the first PDU session of the second card according to the call duration (step S20) includes:
step S21: and when the call duration is greater than or equal to the preset duration, releasing the first PDU session of the second communication card.
In some embodiments, step S21 is implemented by the processing module 22, that is, the processing module 22 is configured to release the first PDU session of the second card when the call duration is greater than or equal to the preset duration.
In some embodiments, step S21 may be implemented by the processor 11, that is, the processor 11 is configured to release the first PDU session of the second card when the call duration is greater than or equal to the preset duration.
Specifically, the main role of releasing the PDU session is to release the corresponding resources, such as the IP address, allocated to the user equipment in the process of establishing the PDU session. The release of the PDU session may be initiated by the electronic device 100 or may be initiated by the data network. In the above scenario, the release of the PDU session is initiated by the electronic device 100 towards the data network and requires the use of radio frequency antenna resources into the electronic device 100 at the time of initiation.
Particularly, since the first communication card and the second communication card share the rf antenna resource, when the first communication card is switched to the default data master card, the first communication card occupies the rf antenna resource, so that the first PDU session on the second communication card cannot be released through a normal path when it needs to be released. Further, when the second communication card is switched to the default data master card again after the first communication card ends the call, because the first PDU session is not released or the release period is late, a new PDU session cannot be established on the second communication card immediately, resulting in slow recovery of the data service of the second communication card.
Then, in order to solve the above problem, in step S21, when the first communication card is switched to the default data master card and the call duration of the first communication card obtained in step S10 is greater than the preset duration, the processor 11 controls the electronic device 100 to directly and locally release the first PDU session established on the second communication card, at which time, the processor 11 does not need to send a release PDU session request to the data network.
In this embodiment, the selected timer is T3582, and the timeout threshold of the timer is 16 seconds, so that the preset duration can be set to 16 seconds. That is, when the call duration of the first communications card acquired in step S10 is greater than 16 seconds, that is, the timer expires, the processor 11 controls the electronic device 100 to locally release the first PDU session established on the second communications card.
In this way, when it is detected that a long-time call is required, the processor 11 controls the electronic device 100 to directly and locally release the first PDU session of the second communication card, so that it is not necessary to release the first PDU session by sending a request for releasing the PDU session to the data network, thereby quickly recovering the data service of the second communication card when the second communication card switches back to the default data master card.
Referring to fig. 5, in some embodiments, after the first communication card ends the call, the method for recovering the data service of the second communication card according to the result of processing the first PDU session (step S30) includes:
step S31: initiating a second PDU session request for creating a second communication card to the data network;
step S32: an instruction returned by the data network is received to establish a second PDU session.
In some embodiments, steps S31 and S32 may be implemented by the recovery module 23. That is, the recovery module 23 is configured to initiate a second PDU session request to create a second communication card to the data network, and to receive an instruction returned by the data network to establish a second PDU session.
In some embodiments, the processor 11 is configured to initiate a second PDU session request to the data network to create a second communications card, and to receive an instruction back from the data network to establish a second PDU session.
Specifically, in order to enable the electronic device 100 to normally perform information interaction with the data network when the second communication card is switched back to the default data master card after the call is ended, the PDU session on the second communication card, that is, the second PDU session, needs to be re-established.
At this time, in steps S31 and S32, according to the 5G-related specification formulated by 3GPP, the electronic device 100 sends a NAS message to the Data Network, where the message includes a second PDU session creation request, and the request carries information such as slice information, DNN (Data Network Name) information, and PDU session ID. The message is sent to an AMF (Access and Mobility Management Function), then the AMF selects a proper SMF (Session Management Function) to send Session establishment information, after the SMF receives the Session establishment information, the SMF cooperates with a UDM (Unified Data Management) and a UPF (User Plane Function) to complete operations of authorizing and authenticating the PDU Session, updating a Session control strategy, selecting an SSC (Session and service continuity) mode, allocating an IP address and the like, then the SMF sends a Session establishment receiving message to the AMF, and the AMF informs a gNB (5G base station) to establish a radio bearer.
To this end, the electronic device 100 receives the resources such as the IP address, the user plane resource, and the control panel resource allocated by the data network in response to the sent second PDU session establishment request, and finally completes the establishment of the second PDU session.
Therefore, when the second communication card is recovered to be the default data master card, the information interaction can be carried out between the newly established second PDU session and the data network, so as to normally use the data service.
As shown in fig. 6, in one scenario, the second communication card is configured as a 5G card and is a default data master card of the electronic device 100. When the electronic device 100 is powered on, the processor 11 may complete network registration by obtaining relevant information on the second communication card, and at this time, the user may use the data service on the second communication card, for example, when the user clicks on an application, a first PDU session may be established between the electronic device 100 and the data network to transfer relevant data to implement information interaction.
When a call is made on the first communication card, the user suspends the data service on the second communication card to answer the call, in order to enable the data service on the second communication card to be continuously used after the call of the first communication card is ended, the processor 11 obtains the call duration of the first communication card, compares the call duration with the preset duration, releases the first PDU session when the call duration is greater than or equal to the preset duration, and immediately reestablishes the second PDU session with the data network after the call is ended, so that the user can continue the data service on the second communication card before the call.
Referring to fig. 7, in some embodiments, processing the first PDU session of the second card according to the call duration (step S20) includes:
step S22: and when the call duration is less than the preset duration, reserving the first PDU session of the second communication card.
In some embodiments, step S22 may be implemented by the processing module 22, that is, the processing module 22 is configured to reserve the first PDU session of the second card when the call duration is less than the preset duration.
In some embodiments, the processor 11 is configured to reserve the first PDU session of the second card when the call duration is less than the preset duration.
Specifically, in the 5G network architecture, a PDU session may be set in an active state or a deactivated state, and data may be transferred between the user equipment and the data network through the PDU session in the active state, but when the PDU session is in the inactive state, part of information is reserved for both a user plane air interface resource and a control plane resource of the PDU session, and at this time, data cannot be transferred between the user equipment and the data network through the PDU session.
Then, in step S22, when it is detected that the call duration is shorter than the preset duration, in order to facilitate fast recovery of the data service of the second communication card, the electronic device 100 still does not send a request for releasing the first PDU session to the data network, and meanwhile locally retains the first PDU session in the inactive state, that is, retains resources such as the IP address allocated by the data network when the first PDU session flow is originally established. Therefore, when the call duration is short, the data service of the second communication card can be quickly recovered after the second communication card is switched to the default data card again so as to be convenient for the user to use.
As shown in fig. 8, in some embodiments, after the first communication card ends the call, the method for recovering the data service of the second communication card according to the result of processing the first PDU session (step S30) includes:
step S33: and controlling the second communication card to carry out data transmission with the data network through the first PDU session, thereby recovering the data service of the second communication card.
In some embodiments, step S33 may be implemented by the recovery module 23, that is, the recovery module 23 is configured to control the second communication card to perform data transmission with the data network through the first PDU session, so as to recover the data service of the second communication card.
In some embodiments, the processor 11 is configured to control the second communication card to perform data transmission with the data network through the first PDU session, so as to recover the data service of the second communication card.
Specifically, in step S33, after the first communication card ends the call, the second communication card is restored to the default data master card, and at this time, based on the partial information of the first PDU session reserved in step S22, the related resources of the first PDU session, such as the user plane resources and the control plane resources, can be restored, so that the first PDU session is in the active state again. In this way, the electronic device 100 can resume data transmission with the data network via the first PDU session to recover the data service on the second card.
Therefore, when it is detected that the call time of the first communication card is shorter than the preset time, the data service on the second communication card is resumed through the reserved first PDU session, so that when the first communication card is switched to the default data master card, the electronic device 100 does not need to initiate a request for releasing the first PDU session to the data network, and after the second communication card is switched to the default data master card again, the electronic device 100 does not need to initiate a request for creating a new PDU session, thereby ensuring fast resumption of the data service on the second communication master card.
The present embodiments provide a non-transitory computer-readable storage medium storing a computer program, which, when executed by one or more processors 11, causes the processors 11 to perform a communication method of:
s10: when a first communication card is used for communication, the communication time length is obtained;
s20: processing a first PDU session of a second communication card according to the call duration;
s30: and after the first communication card finishes the conversation, recovering the data service of the second communication card according to the result of processing the first PDU conversation.
In one embodiment, a user accesses a 3GPP network to browse a website, use an application program, and so on for data services through a second communication card installed on the electronic device 100, and then the electronic device 100 and the data network perform information interaction through a first PDU session to transfer related data. When a user answers a call suddenly typed into the first communication card, the first communication card is switched to the default data master card, and at the moment, the data service on the second communication card is suspended, so that the first PDU session established on the second communication card is in an inactive state under the influence of the default data master card.
In order to enable actions such as website browsing, application program using and the like performed on the second communication card not to be affected after the call of the first communication card is ended, the processor 11 obtains the call duration of the first communication card, compares the call duration with the preset duration, locally releases the first PDU session when the call duration is greater than or equal to the preset duration, and immediately reestablishes the second PDU session of the second communication card after the call is ended. When the call duration is shorter than the preset duration, the first PDU session in the inactive state is retained, and after the call is ended, the establishment of user plane resources and control plane resources related to the first PDU session can be resumed, so that the electronic device 100 can perform information interaction with the data network through the first PDU session again according to the second communication card.
Specifically, it can be understood by those skilled in the art that all or part of the flow in the method for implementing the above embodiments may be implemented by instructing the relevant hardware through a computer program. The computer program may be stored in a non-transitory computer readable storage medium, and when executed, may include the processes of the embodiments of the methods described above.
