Description

Communication state updating method and device

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a communication state updating method and equipment.

Background

Currently, a single-pass technology of a Subscriber Identity Module (SIM) card means that a plurality of SIM cards simultaneously inserted into a User Equipment (UE) can simultaneously maintain a registration state, but only one SIM card can be allowed to receive and transmit data services at the same time (since the UE only has one set of radio frequency resources).

Thus, when the SIM card 1 of the UE starts data traffic to perform a data service, if the SIM card 2 needs to perform IP Multimedia Subsystem (IMS) re-registration or re-subscription, the UE allocates radio frequency resources to the SIM card 2 for use, so that the SIM card 2 occupies the radio frequency resources of the SIM card 1. Particularly, when the UE performs a data service (e.g., an online game service) requiring low latency through the SIM card 1, the data transmission of the SIM card 1 is interrupted due to the SIM card 2 seizing a radio frequency resource, which results in a high latency, and thus data transmission fails.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.

In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

In the description of the embodiments of the present invention, unless otherwise specified, "a plurality" means two or more, for example, a plurality of processing units means two or more processing units; plural elements means two or more elements, and the like.

IMS is The basic scheme for providing voice and video communication over Long Term Evolution (LTE), and will also be The basis for providing voice and video communication over The fifth-Generation mobile communication technology (5 th-Generation, 5G) in The future. The IMS provides a call service through a Packet Switch (PS) domain connected based on a Transmission Control Protocol (TCP)/Internet Protocol (IP) based on a Session Initiation Protocol (SIP), and makes good use of bandwidth and delay characteristics of LTE and 5G, thereby providing a high-quality call service.

The SIP protocol requires that the UE register with the SIP server before using the SIP service, and that a re-registration message (whose period is controlled by a registration timer) must be sent to the server periodically to keep the state on the server synchronized with the state of the UE and to update the encryption information in time. Here, registration and re-registration are both accomplished by sending a registration (REGISTER) message to the server at regular intervals.

Meanwhile, a subscription service exists in the SIP protocol, and the UE can subscribe to a specific event at the server. When an event occurs, the server can actively send a notification message, so that the state synchronization of the UE and the server can be ensured. The SIP protocol specifies that subscriptions also need to be refreshed periodically (with the period controlled by a subscription timer) to maintain state synchronization. Here, subscription and subscription refresh (i.e. re-subscription) are all completed by the UE sending a subscription (SUBSCRIBE) message to the server at regular time.

It can be seen that the above REGISTER message and SUBSCRIBE message need to be sent periodically even if no call is made. Thus, there are the following problems: if the current SIM card 1 is using radio frequency resources to perform preset services (such as services of online games, online video watching, online video chat, etc.) with high requirements for low latency, and the SIM card 2 needs to send REGISTER messages or SUBSCRIBE messages (and in order to receive the called call in time, the UE must keep the SIP registration state all the time, that is, must send these messages periodically), the SIM card 2 will need to seize the radio frequency resources, so that the SIM card 2 seizes the radio frequency resources to cause interruption of data transmission of the SIM card 1, generate high latency (cause jamming), and further may cause data transmission failure due to the high latency, thereby seriously affecting user experience.

And because the re-registration and re-subscription can not be delayed, if the UE does not trigger the IMS re-registration after time out, the registration state of the UE is lost, and if the UE does not trigger the IMS re-subscription after time out, the subscription state of the UE is also ended. However, the SIP protocol provides that if the UE performs re-registration and re-subscription before the UE advances, the registration state and the subscription state can be refreshed normally.

Therefore, in view of the above technical problems, the following solutions exist in the prior art: when the preset service executed by the SIM card 1 is in an idle state, the UE allocates the radio frequency resource to the SIM card 2 for use, and sends the re-registration message or the re-subscription message of the SIM card 2 to the network device corresponding to the SIM card 2 in advance, so that the re-registration message or the re-subscription message of the SIM card 2 can be normally processed by the network device. However, this solution has the following problems: in the process that the SIM card 2 completes the re-registration or the re-subscription status update by using the radio frequency resource, if the UE needs to continue to execute the preset service through the SIM card 1, the data transmission of the SIM card 1 may be interrupted due to the SIM card 2 occupying the radio frequency resource, which may result in a higher time delay, and further may result in a data transmission failure due to the higher time delay.

The embodiment of the invention provides a communication state updating method, wherein UE (user equipment) can send a request message to core network equipment corresponding to a second SIM card through access network equipment corresponding to the second SIM card within a preset time period when detecting that the UE carries out a preset service after the preset time period through a first SIM card, wherein the request message is used for requesting the core network equipment to update a target state; and under the condition that a response message fed back by the core network equipment is received from the access network equipment through the second SIM card, controlling the second SIM card to update the target state according to the response message, wherein the response message is used for indicating that the core network equipment updates the target state. According to the scheme, under the condition that the UE detects that the UE carries out a preset service after a preset time through the first SIM card, the UE sends a request message to the core network equipment corresponding to the second SIM card through the access network equipment corresponding to the second SIM card in advance within the preset time so as to control the second SIM card to update the target state, so that the target state of the second SIM card is updated under the condition that the second SIM card does not occupy radio frequency resources, and higher time delay caused by data transmission failure of the first SIM card can be avoided, and further data transmission failure caused by higher time delay can be avoided.

The technical scheme provided by the invention can be applied to various communication systems, such as a 5G communication system, a future evolution system or a plurality of communication convergence systems and the like. The method can be applied to a variety of application scenarios including, for example, Machine-to-Machine (Machine, M2M), D2M, macro-micro Communication, enhanced Mobile Broadband (eMBB), ultra-high reliability and ultra-Low Latency Communication (urrllc), and mass internet of things Communication (mtc).

In order to solve the above technical problem, embodiments of the present invention provide a communication status updating method and apparatus, and a detailed description is provided below with reference to the accompanying drawings for the communication status updating method and apparatus provided in embodiments of the present invention.

Based on the communication system shown in fig. 1, an embodiment of the present invention provides a communication status updating method, which may include steps 201 to 202 as shown in fig. 2.

Step 201, when detecting that the UE performs a preset service after a predetermined time period through the first SIM card, the UE sends a request message to core network equipment corresponding to the second SIM card through access network equipment corresponding to the second SIM card within the predetermined time period.

The request message is used for requesting the core network device to update the target state of the second SIM card.

In this embodiment of the present invention, the UE includes the first SIM card and the second SIM card, and may further include more SIM cards.

In the embodiment of the invention, the UE needs to execute the preset service through the first SIM card, and the preset service requires low time delay; the second SIM card needs to update the target status periodically (for example, the second SIM card is registered with the IMS VOLTE service, and needs to be re-registered or re-subscribed periodically).

In the embodiment of the invention, the user can set the preset service in the UE through input according to the actual use requirement. For example, the user can set up a royal glory game, a video phone call with a target character, watch a target video, etc. in the UE as a preset service by inputting.

In the embodiment of the present invention, the communication state refers to a service state that can ensure normal information interaction between the UE and a network device (e.g., a core network device).

For example, the request Message may be an IMS re-registration Message, an IMS re-subscription Message, a notification (Message) Message (e.g., a short Message or a phone Message), a Non-Access Stratum (NAS) Message, a Radio Network Subsystem (RNS) Message, a Radio Resource Control (RRC) Message, or other request messages, and the embodiment of the present invention is not limited thereto. As such, the target states (i.e. communication states) correspond to an IMS registration state, an IMS subscription state, a notification state (a short message state or a telephone state), a non-access stratum state, a radio network subsystem state, a radio resource control state, and the like, and may be other states, which is not limited in the embodiment of the present invention.

Optionally, if the UE receives an input that the user starts a preset service, it may be detected that the UE performs the preset service after a predetermined time period through the first SIM card. The method comprises the steps that the UE sends first notification messages to a first SIM card and a second SIM card respectively under the condition that the UE carries out a preset service after a preset time length through the first SIM card is detected, and the first notification messages are used for notifying the UE of carrying out the preset service after the UE is detected to carry out the preset service after the preset time length through the first SIM card. After receiving the first notification message, the first SIM card detects the network connection status of itself and performs corresponding connection update. After receiving the first notification message, the second SIM card sends a request message to the core network device in advance to ensure the update of the target state.

The core network equipment receives the request message from the UE through the access network equipment, updates the target state according to the request message and feeds back a response message to the UE. The core network device feeds back the response message to the UE, which may be: and the core network equipment sends a response message to the UE through the access network equipment.

Step 202, the UE controls the second SIM card to update the target state according to the response message when receiving the response message fed back by the core network device from the access network device through the second SIM card.

The response message is used to indicate that the core network device has updated the target status.

Alternatively, the above steps 201 to 202 can be specifically realized by the following scheme.

The UE sends the request message to the access network equipment through the second SIM card within a preset time when detecting that the UE carries out a preset service after the preset time through the first SIM card; the access network equipment receives the request message from the second SIM card and sends the request message to the core network equipment; the core network equipment receives the request message from the access network equipment, updates the target state according to the request message and sends a response message to the access network equipment; the access network equipment receives the response message from the core network equipment and sends the response message to the second SIM card; and the UE receives the response message from the access network equipment through the second SIM card and controls the second SIM card to update the target state according to the response message.

The following describes an exemplary communication status updating method provided by an embodiment of the present invention in detail with reference to fig. 2.

Illustratively, as shown in fig. 3, the communication state updating method provided by the embodiment of the present invention includes steps 301 to 306 described below.

Step 301, when detecting that the UE performs a preset service after a predetermined time period through the first SIM card, the UE sends the request message to the access network device through the second SIM card within the predetermined time period.

The access network device receives the request message from the second SIM card, where the request message is used to request the core network device corresponding to the second SIM card to update the target state of the second SIM card when the UE detects that the first SIM card of the UE performs a preset service after a predetermined time.

Optionally, in this embodiment of the present invention, after receiving the request message, the core network device updates the target state according to the request message.

Optionally, the request message includes time information for indicating a target time, and the request message is used to indicate the core network device to update the target state at the target time. After receiving the request message, the core network device updates the target state at the target time according to the request message.

Optionally, in the embodiment of the present invention, the time information may be time period information, time information, or duration information, which is not limited in the embodiment of the present invention. The time period information may be a time period from a time when the UE sends the request message (or receives the request message from the core network device) to an update time. The time information is the time at which the target state is updated. The duration information may be a predetermined duration from the time the UE sends the request message (or receives the request message from the core network device).

It can be understood that, in the embodiment of the present invention, the preset update time information is used to indicate: under normal conditions, the UE and the core network equipment agree on the target state updating time; the UE may determine the preset update time information according to an update period of the target state agreed in advance between the UE and the core network device.

It can be understood that, in the embodiment of the present invention, the delay update time information is used to indicate: and under the condition that the UE executes the preset service through the first SIM card, in order to ensure the update of the target state, the UE and the core network equipment re-agree the update time of the target state. The UE may determine the time delay update time information according to an update period of a target state agreed in advance by the UE and the core network device, and time information of a preset service executed by the UE through the first SIM card, which is estimated by the UE; the UE can also determine time delay updating time information according to preset time information; the embodiments of the present invention are not limited.

Optionally, the time information includes preset update time information, and the core network device determines the target time according to the preset update time information.

Optionally, the time information includes time delay update time information, and the core network device determines the target time according to the time delay update time information.

Optionally, the time information includes preset update time information and delayed update time information, and the core network device determines the target time according to the preset update time information and the delayed update time information.

Illustratively, the core network device may determine the target time according to the preset update time information and the delayed update time information according to a preset rule. For example, the preset rule is: before the updating time indicated by the preset updating time information arrives, the UE stops executing the preset service through the first SIM card, and the target time is the updating time indicated by the preset updating time information; when the updating time indicated by the preset updating time information arrives, the UE still executes the preset service through the first SIM card, and the target time is the updating time indicated by the delayed updating time information. The preset rule may also be other feasibility rules, and the embodiment of the present invention is not limited.

In the embodiment of the invention, the time information is added in the request message, so that the target state of the second SIM card can be better ensured to be in an activated state in the process that the UE executes the preset service through the first SIM card.

In the embodiment of the present invention, the time information includes at least one of the following items: the preset updating time information and the delayed updating time information can better ensure that the target state of the second SIM card is in an activated state in the process that the UE executes the preset service through the first SIM card.

It can be understood that, in the embodiment of the present invention, before the UE sends the request message to the Access network device through the second SIM card, the UE controls the second SIM card to encapsulate a message body of the request message, time information (or may not include the time information), a Temporary-International mobile subscriber Identity (T-IMSI) used by the second SIM card in a previous registration, an IP address of the core network device, an Access Point Name (APN), and related authentication information, so as to generate the request message, and a description of a specific encapsulation process of the request message may refer to a description of an existing related technology, which is not described herein again.

Step 302, the access network device sends the request message to the core network device.

It can be understood that, in the embodiment of the present invention, after receiving the request message from the second SIM card, the access network device decapsulates the request message, resolves the IP address of the core network device, and then sends the request message to the core network device according to the IP address of the core network device.

The core network device receives a request message from access network equipment corresponding to a second SIM card of the UE, wherein the request message is used for requesting the core network device to update a target state of the second SIM card when the UE detects that a preset service is performed on a first SIM card of the UE after a preset time.

Step 303, the core network device updates the target state according to the request message.

It is understood that the core network device updates a corresponding service state of the second SIM card (e.g., IMS re-registration service state (or IMS re-subscription service state)) according to the request message, puts a related service of the second SIM card in an Activated (Activated) state, and resets a state Timer (Timer) in the core network device (e.g., resets the re-registration Timer or resets the re-subscription Timer). Then, the core network device sends the processing result (Response) to the access network device, so that the access network device feeds back the Response to the UE, and the UE refreshes the corresponding service state of the second SIM card.

Optionally, in a case that the request message includes time information for indicating a target time, and the request message is used to indicate the core network device to update the target state at the target time, the step 303 may be specifically implemented by a step 303a described below.

Step 303a, the core network device updates the target state at the target time according to the request message.

Optionally, the time information comprises at least one of: presetting updating time information and delayed updating time information;

wherein the preset update time information is used for indicating: the target state is updated at the moment when the UE does not execute the preset service through the first SIM card; the delay update time information is used to indicate: and the target state is updated at the moment when the UE executes the preset service through the first SIM card.

Optionally, the core network device determines a target time according to the request message, and then updates the target state at the target time.

Optionally, the core network device determines a target time according to the time information in the request message, then refreshes a state update timer corresponding to the second SIM card, and updates the target state when the state update timer is overtime.

Optionally, the core network device determines a target time according to the time information in the request message, then resets a state update timer (closes the original state update timer corresponding to the second SIM card), and updates the target state when the state update timer is overtime.

Step 304, the core network device sends a response message to the access network device.

The access network device receives a response message from the core network device.

Step 305, the access network device sends the response message to the second SIM card.

The UE receives the response message from the access network device through the second SIM card.

Optionally, the access network device may directly send the response message to the second SIM card, or may send a paging message to the second SIM card, where the paging message carries the response message.

This step 305 may be implemented, for example, specifically by step 305a described below.

Step 305a, the access network equipment sends a paging message to the second SIM card.

The paging message carries the response message.

And the UE receives the paging message from the access network equipment through the second SIM card.

It can be understood that the paging message is relatively small and the processing time is short, so the connection state of the first SIM card is less affected.

It should be noted that, in practical cases, the response message is usually transmitted through the paging message in the case that the response message is small.

In the embodiment of the invention, the access network equipment sends the paging message to the second SIM card, so that higher time delay caused by data transmission failure of the first SIM card can not be caused, and further data transmission failure is caused by higher time delay.

Step 306, the UE controls the second SIM card to update the target status according to the response message.

The UE controls the second SIM card to update a target state of the second SIM card (e.g., IMS registration state (or IMS subscription state)) according to the response message, and resets the state timer (e.g., resets the re-registration timer (or resets the re-subscription timer)) to complete an update procedure of the target state.

The embodiment of the invention provides a communication state updating method, wherein UE can send a request message to core network equipment corresponding to a second SIM card through access network equipment corresponding to the second SIM card within a preset time period when detecting that the UE carries out a preset service after the preset time period through a first SIM card, wherein the request message is used for requesting the core network equipment to update a target state; and under the condition that a response message fed back by the core network equipment is received from the access network equipment through the second SIM card, controlling the second SIM card to update the target state according to the response message, wherein the response message is used for indicating that the core network equipment updates the target state. According to the scheme, under the condition that the UE detects that the UE carries out a preset service after a preset time through the first SIM card, the UE sends a request message to the core network equipment corresponding to the second SIM card through the access network equipment corresponding to the second SIM card in advance within the preset time so as to control the second SIM card to update the target state, so that the target state of the second SIM card is updated under the condition that the second SIM card does not occupy radio frequency resources, and higher time delay caused by data transmission failure of the first SIM card can be avoided, and further data transmission failure caused by higher time delay can be avoided.

Optionally, in the embodiment of the present invention, when detecting that the UE performs a preset service after a predetermined time period through the first SIM card, the UE may send a first notification message to the access network device through the second SIM card.

Exemplarily, in conjunction with fig. 3, as shown in fig. 4, after step 301, the communication state updating method provided by the embodiment of the present invention may further include steps 307 to 308 described below.

Step 307, the UE sends a first notification message to the access network device through the second SIM card when detecting that the UE performs the preset service after the predetermined time length through the first SIM card.

Optionally, the UE sends a first notification message to the access network device through the second SIM card within the predetermined time period when detecting that the UE performs the preset service after the predetermined time period through the first SIM card.

The first notification message is used for indicating the access network device to filter a target service, where the target service is: and the service which is received from the core network equipment and needs to be forwarded to the second SIM card, and the time length of the target service received by the UE through the second SIM card is greater than or equal to a preset threshold value.

And the access network equipment receives a first notification message from the second SIM card, wherein the first notification message is used for notifying the UE of carrying out the preset service after detecting that the UE passes through the first SIM card for the preset time.

After receiving the first notification message, the access network device may analyze that the UE performs the preset service after the predetermined duration through the first SIM card, and when receiving a target service (a time-consuming service, a service that consumes time in a processing process) issued by the core network device to the second SIM card, may perform related filtering processing, so as to ensure that the time-consuming service of the second SIM card is not issued to the second SIM card processing of the UE.

Step 308, the access network device filters the target service according to the first notification message, in case of receiving the target service.

The target service is as follows: and the service which is received from the core network equipment and needs to be forwarded to the second SIM card, and the time length of the target service received by the UE through the second SIM card is greater than or equal to a preset threshold value.

It should be noted that, in the embodiment of the present invention, the execution sequence between the steps 301 to 302 and the steps 307 to 308 is not limited, for example, the steps 301 to 302 may be executed first, and then the steps 307 to 308 may be executed; the steps 307 to 308 may be performed first, and then the steps 301 to 302 may be performed, or the steps 301 to 302 and the steps 307 to 308 may be performed simultaneously.

Illustratively, when the above steps 301 to 302 and 307 to 308 are performed simultaneously, the UE may send the request message and the first notification message to the access network device simultaneously through the second SIM card; the UE may also control the second SIM card to encapsulate the request message and the first notification message into a first message, and then send the first message to the access network device through the second SIM card, where the first message carries the request message and the first notification message; after receiving the first message, the access network equipment decapsulates the first message and analyzes the request message and the first notification message.

In the embodiment of the invention, the UE sends a first notification message to the access network equipment through the second SIM card under the condition that the UE carries out the preset service after the preset time through the first SIM card, and the access network equipment filters the target service according to the first notification message under the condition that the target service is received. Therefore, in the process that the UE carries out the preset service after the preset time length through the first SIM card, the second SIM card cannot occupy the radio frequency resource due to the target service, and further higher time delay caused by data transmission failure of the first SIM card can be avoided, and further data transmission failure caused by the higher time delay can be avoided.

Optionally, in this embodiment of the present invention, when detecting that the UE stops executing the preset service through the first SIM card, the UE may send a first notification message to the access network device through the second SIM card.

Exemplarily, in conjunction with fig. 4, as shown in fig. 5, after step 308, the communication status updating method provided by the embodiment of the present invention may further include steps 309 to 310 described below.

Step 309, the UE sends a second notification message to the access network device through the second SIM card when detecting that the UE stops executing the preset service through the first SIM card.

The second notification message is used for instructing the access network equipment to forward the target service to the UE.

It can be understood that, in the embodiment of the present invention, the UE stops executing the preset service through the first SIM card, which may include that the UE closes the preset service according to the user input, or that the UE suspends the preset service according to the user input (that is, the preset service of the first SIM card is currently in an idle state), which is not limited in the embodiment of the present invention.

And the access network equipment receives a second notification message from the second SIM card, wherein the second notification message is used for notifying the UE to stop executing the preset service through the first SIM card.

And step 310, the access network device forwards the target service to the second SIM card according to the second notification message, in the case that the target service is received.

It should be noted that, before the access network device receives the target service, if the first notification message is received and the second notification message is not received, the access network device filters the target service; and if the second notification message is received, the access network equipment forwards the target service to the second SIM card.

In the embodiment of the invention, the UE sends a second notification message to the access network equipment through a second SIM card under the condition that the UE stops executing the preset service through the first SIM card; and the access network equipment forwards the target service to the second SIM card under the condition of receiving the target service according to the second notification message. Therefore, under the condition that the UE stops executing the preset service through the first SIM card, normal communication service between the second SIM card and the core network equipment can be ensured.

It should be noted that, the UE, the access network device, and the core network device may circularly perform steps 301 to 310, which is not limited in the embodiment of the present invention.
