Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application. The reference numerals in the present application are only used for distinguishing the steps in the scheme, and are not used for limiting the execution sequence of the steps, and the specific execution sequence controls the description in the specification.
In order to solve the problems in the prior art, the embodiment of the application provides a communication method and device of a voice short message service and a computer readable storage medium.
Fig. 1 is a flow chart of a communication method of a voice short message service according to an embodiment of the present application, where the communication method of a voice short message service according to an embodiment of the present application is applied to a user subscription management network element. As shown in fig. 1, the communication method of the voice short message service according to the embodiment of the present application includes the following steps 102 to 110.
Step 102, receiving an MSC registration request triggered by a mobile switching center MSC when a wireless network type accessed by a target user changes, where the MSC registration request carries a user identifier of the target user, information related to the MSC, and a cell identifier indicating the wireless network type, and the MSC registration request is used for requesting to register a voice short message service of a first wireless network currently accessed by the target user through the MSC.
When the target user accesses the MSC network element for registering the voice short message service, the MSC needs to send a registration request to a user subscription management network element, such as an HLR, an HSS or a UDM, so as to update the related information of the MSC where the target user is located, and meanwhile, the MSC network element obtains the subscription data of the target user from the user subscription management network element (hereinafter, the HSS network element is taken as an example). Here, the target user refers to a user corresponding to a subscriber identity card (Subscriber Identity Module, SIM) inserted by the mobile terminal device.
When the type of the wireless network accessed by the target user changes, for example, due to network coverage, the user switches from the 4G network to the 2G network, the MSC network element is triggered to send a new registration request to the HSS network element. The registration request sent by the MSC carries a user identifier of the target user, for example, a user identifier corresponding to the SIM card, and further includes related information, such as a location of the MSC, and further includes a cell identifier for indicating a type of the wireless network, where the cell identifier is used to indicate a type of the first wireless network that the target user currently accesses.
Optionally, the first wireless network type includes a 2G network, a 3G network, and a 4G network, and cell identifiers corresponding to the different types of first wireless networks are different.
In one embodiment, different types of wireless networks may be distinguished by different values by numerical values as cell identities.
For example, the value corresponding to the cell identifier is 0, which indicates that the wireless network type is a legacy 2G network; a value of 1, indicating that the wireless network type is a legacy 3G network; a value of 2 indicates that the wireless network type is a 4G network, including a 4G network and a 5GNAS network.
And the registration request sent by the MSC network element is used for requesting the HSS network element to register the voice short message service loaded by the first wireless network which is accessed currently for the target user.
Step 104, determining the type of the first wireless network according to the cell identifier.
For example, the type of the wireless network currently accessed by the target user is determined by the value corresponding to the cell identifier, and the type of the wireless network is one of the 2G, 3G and 4G networks.
And step 106, judging whether the target user registers the voice short message service of the second wireless network through the IP multimedia subsystem IMS according to the user identification.
The HSS network element receives the signing registration information of each user registering the voice short message service, and stores the relevant data of the user, and the relevant data is associated with the user identification. The type of wireless network that registers bearer traffic with the HSS network element includes registering traffic for the 2G, 3G, and 4G networks described above with the MSC network element, as well as registering traffic for the 5GSA network with the IMS network element. Therefore, the HSS network element stores MSC registration information and IMS registration information corresponding to different users at the same time.
Optionally, according to the user identifier, determining whether the target user registers the voice short message service of the second wireless network through the IMS includes: searching IMS registration information stored by the user subscription management network element; judging whether the IMS registration information matched with the user identification exists in the stored IMS registration information; and under the condition that the IMS registration information matched with the user identification exists, determining that the target user registers the voice short message service of the second wireless network through the IMS.
According to the user identification carried in the MSC registration request, the signing registration related data of the target user can be obtained, wherein the signing registration related data comprises corresponding MSC registration information and/or IMS registration information.
If the user identification of the target user can be matched with the target IMS registration information stored in the HSS network element, the voice short message service of the wireless network, which is registered by the target user through the IMS network element, is judged.
Optionally, the second wireless network comprises one of a 4G network and a 5G network.
Currently, a wireless network carrying voice short message service registered through an IMS network element is only applicable to VOLTE service carried through a 4G network and a 5G network.
And step 108, processing the MSC registration request according to the type of the first wireless network under the condition that the target user registers the voice short message service of the second wireless network through the IMS so as to only reserve MSC registration information of the target user registering the voice short message service through the MSC or IMS registration information of the voice short message service through the IMS.
In the above step, if it is determined that the target user registers the voice short message service of the 4G network or the 5G network through the IMS network element, it is indicated that the HSS network element currently stores the IMS registration information of the target user. Under the condition that the current target user registers the voice short message service of the first wireless network type through the MSC network element, if the HSS network element normally processes the registration request of the MSC network element according to a preset flow or a default flow, MSC registration information of the target user is stored at the HSS network element. Namely, the HSS network element simultaneously stores IMS registration information and MSC registration information of the target user, so that voice short message service of the target user is registered in the double network domains, and network domain selection errors and network resource waste are caused when the service is executed.
In this regard, in one embodiment of the present application, optionally, in a case that the target user registers the voice sms service of the second wireless network through the IMS, processing the MSC registration request according to the type of the first wireless network includes: deleting IMS registration information stored by the user subscription management network element when the target user registers the voice short message service of the second wireless network through IMS under the condition that the first wireless network accessed by the target user is a 2G network or a 3G network; and processing the MSC registration request according to a preset flow, and storing MSC registration information of the voice short message service of the first wireless network registered by the target user through the MSC.
If the target user uses the VOLTE service, but switches to access from the 2G or 3G network due to network coverage and other reasons, the HSS network element stores two registration information of MSC and IMS of the target user according to the prior art, and the user is registered in a double domain, but only the MSC network element corresponds to the network domain to use the service, thereby wasting network resources.
Therefore, in this embodiment, if the target user currently accesses the legacy 2G network or the 3G network, the MSC network element carries the cell identifier of the wireless network type corresponding to the target user 2G network or the 3G network when sending the registration request to the HSS network element. After receiving the registration request of the MSC, the HSS network element judges that the target user accesses from the system 2G network or the 3G network based on the cell identification of the wireless network type, and further judges that the HSS network element stores the IMS registration information of the target user, then the IMS registration information is cleared, the MSC registration request is processed normally, so that the storage information of the HSS network element is accurate when the target user accesses from the 2G network or the 3G network, and the single network domain registration is realized.
Therefore, invalid IMS registration information in the HSS network element can be timely cleared, network resources are saved, accurate single domain registration of a user is realized, and domain selection errors possibly existing in the double network domains are avoided.
In another embodiment of the present application, optionally, in a case that the target user registers the voice sms service of the second wireless network through IMS, processing the MSC registration request according to the type of the first wireless network includes: refusing to process the MSC registration request under the condition that the first wireless network accessed by the target user is a 4G network; and reserving IMS registration information stored by the user subscription management network element when the target user registers the voice short message service of the second wireless network through IMS.
For 4G network and 5GNSA network users, it is usually necessary to register to HSS through MSC network element and IMS network element at the same time, where the HSS network element normally prefers network domain to IMS network, and provides called service for the users through VOLTE service. And the MSC network domain registered by the MSC network element is used as the 'bottom of the VOLTE service' selection, and the communication path corresponding to the MSC network domain is used for providing the voice short message service for the user under the condition that the IMS network domain can not normally provide the VOLTE service.
Namely, the HSS network element stores two registration information of MSC and IMS at the same time, and the user is registered for two domains. Although both network domains can bear voice short message service, the network is planned to be the domain and preferentially select to the IMS network, and the voice short message service is carried out through VOLTE. The communication path corresponding to the MSC network domain is basically idle, and network resources are occupied.
Therefore, in this embodiment, if the target user accesses the MSC network element from the 4G network, the MSC network element carries the cell identifier of the radio network type corresponding to the target user 4G network when sending the registration request to the HSS network element. After receiving the registration request of the MSC network element, the HSS network element judges that the target user accesses from the 4G network based on the cell identification of the wireless network type, and further judges that the HSS network element stores IMS registration information, the access of the MSC network element is refused, for example, the reason for refusing is unknown to the registered user, so that the subsequent continuous retry of the target user in the 4G network is avoided, the signaling from the terminal equipment (UE) of the target user to the MSC network element and from the MSC network element to the HSS network element is reduced, and the occupation of the resources of network processing signaling is avoided.
Therefore, the consumption of system resources is avoided, the fact that a user only has single domain registration of an IMS network domain on the HSS network element side is achieved, the accurate single domain registration of the user is achieved, and the expectation that a voice short message service domain is preferentially selected to the IMS network by network planning is met, namely, the registered user of VOLTE performs voice short message service through the VOLTE network.
Meanwhile, under the scene that the user closes the VOLTE function, the user can access to the wireless network corresponding to the MSC network domain from the 4G network to continue to bear the voice short message service, and the voice service availability of the user is ensured.
Step 110, providing communication of voice short message service for the target user according to the wireless network corresponding to the reserved registration information.
Under the condition that the HSS network element originally stores two registration information of the MSC and the IMS of the target user at the same time, after deleting the IMS registration information, the reserved registration information is MSC registration information. Under the condition that the HSS network element originally only stores the IMS registration information of the target user, the reserved registration information is MSC network element information which is generated after processing the registration information sent by the MSC network element and is stored in the HSS network element.
Thus, in this step, the communication of the voice short message service is provided for the target user through the wireless network corresponding to the MSC registration information.
Optionally, the method further comprises: and under the condition that the target user does not register the voice short message service of the second wireless network through the IMS, processing the MSC registration request according to a preset flow, and storing MSC registration information of the voice short message service of the first wireless network registered by the target user through the MSC.
Here, the preset flow is a default flow for normally processing the MSC registration request, and can implement a network of the first wireless network type registered by the target user through the MSC network element as a network currently carrying the voice short message service.
Optionally, after receiving the MSC registration request triggered when the type of the wireless network accessed by the target user changes, the method further includes: judging whether the MSC registration request carries a cell identifier or not; under the condition that the cell identifier is not carried, determining whether to allow processing of the MSC registration request according to a preset network configuration strategy; or judging whether the cell identifier carried by the MSC registration request indicates a 2G network, a 3G network or a 4G network; if not, refusing to process the MSC registration request.
If the MSC registration request does not carry the cell identification indicating the wireless network type, the network configuration is controllable, namely the processing strategy of the network is self-defined, and whether the access request of the MSC network element is processed to allow the MSC network element to normally access or the access request of the MSC network element is refused to refuse the access of the MSC network element is determined.
If the cell identity indicating the type of wireless network carried in the MSC registration request indicates that the access network is a network other than the type of the first wireless network, e.g. a 2G network, a 3G network or a 4G network, the access request of the MSC network element may be rejected.
The above embodiments relate to carrying a cell identifier indicating a wireless network type in an MSC registration request, and performing voice short message service registration and communication according to the correspondingly carried cell identifier.
In another embodiment, the voice sms registration and communication may also be performed through an IMS registration request, which may not carry a cell identifier indicating the type of wireless network.
Optionally, the method further comprises: receiving an IMS registration request triggered when the type of a wireless network accessed by a target user changes, wherein the IMS registration request carries a user identifier of the target user and IMS related information, and the IMS registration request is used for requesting to register a voice short message service of the wireless network accessed by the target user currently through IMS; judging whether the target user registers the voice short message service of the wireless network through MSC according to the user identification; under the condition that the target user registers the voice short message service of the wireless network through the MSC, deleting MSC registration information stored by the user subscription management network element when the target user registers the voice short message service of the corresponding wireless network through the MSC; processing the IMS registration request according to a preset flow, and storing IMS registration information of a voice short message service of a wireless network which is currently accessed by the target user through IMS registration; and providing communication of voice short message service for the target user according to the wireless network corresponding to the IMS registration information.
In this embodiment, the IMS registration request sent by the IMS network element to the HSS network element carries the user identifier of the target user and IMS related information, which is suitable for access of the 4G and 5G types of users. When the target user registers the voice short message service through the IMS network element, after the HSS network element receives the registration request of the IMS network element, the HSS network element further judges whether MSC registration information of the target user is stored in the HSS network element or not on the basis of the traditional normal process flow of processing the IMS registration request.
The judging mode is similar to the above judging mode for judging whether the MSC registration information of the target user is stored, for example, the HSS network element searches the stored MSC registration information, judges whether the MSC registration information matched with the user identification of the target user carried in the IMS registration request exists in the stored MSC registration information, and determines that the HSS network element stores the MSC registration information of the target user under the condition that the MSC registration information matched with the user identification exists.
If the MSC registration information of the target user is stored, triggering the HSS network element to clear the corresponding MSC registration information, and normally processing the IMS registration request, so that the VOLTE user is ensured to have single domain registration of the IMS domain only.
Therefore, the HSS stores accurate information, can ensure that VOLTE users only register in a single domain of an IMS domain, clear and eliminate invalid occupation of network resources by MSC registration information under the current network scene (for example, poor quality of a 2G network or a 3G network or shortage of network resources), and realize accurate single domain registration of the users while saving the network resources.
