Description

Method, device, electronic device and storage medium for sending terminal attachment request

Technical field

The present application belongs to the field of communications, and specifically relates to a method, device, electronic device and storage medium for sending a terminal attachment request.

Background technique

In related technologies, due to the inability of 4G base stations to provide continuous coverage in the early stages of the development of fourth-generation communication technology (4G for short), problems occurred when Voice over Long-Term Evolution (VOLTE) terminals performed network registration or location updates. The phenomenon that the Internet Protocol Multimedia Subsystem ((Internet Protocol, IP) Multimedia Subsystem, IMS) domain cannot page the end user. In order to cope with the above phenomenon, in related technologies, VOLTE terminals will initiate a joint attachment request and jointly attach to the mobility management entity (Mobility Management Entity, MME) and the mobile switching center (Mobile Switch Center, MSC), thereby paging in the IMS domain. When the end user is not available, an attempt is made to page the user through the jointly attached MSC.

However, MSC has no evolution path in the 3rd Generation Partnership Project (3GPP) specifications. Most of them have been online for more than 10 years. They occupy a lot of energy consumption and computer room space, and the equipment failure rate continues to increase. Operator equipment operation and maintenance work brings huge security risks.

Moreover, the current 4G wireless network has achieved continuous coverage and has exceeded the coverage of the second generation communication technology (2G for short). There is basically no scenario in the existing network where the user cannot be paged by IMS and then paging through the MSC in the 2G network. In this way Attaching the VOLTE terminal to the MSC will result in extremely low user data utilization on the MSC. However, VoLTE users within the operator account for a large proportion of the total users. Due to joint attachment, these users will occupy MSC resources, resulting in high equipment utilization. Therefore, in order to avoid the problem of low user data rate on the MSC due to high equipment utilization of user data on the MSC, it is urgent to find a method to turn off the joint attachment of VoLTE users to the MSC in related technologies.

Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

Specifically, in related technologies, due to the inability of 4G base stations to provide continuous coverage in the early stages of the development of the fourth generation communication technology (4G for short), the network registration or location of Voice over Long-Term Evolution (VOLTE) terminals was During the update, there is a phenomenon that the Internet Protocol Multimedia Subsystem ((Internet Protocol, IP) Multimedia Subsystem, IMS) domain cannot page the end user. In order to cope with the above phenomenon, in related technologies, VOLTE terminals will initiate a joint attachment request and jointly attach to the mobility management entity (Mobility Management Entity, MME) and the mobile switching center (Mobile Switch Center, MSC), so that paging in the IMS domain cannot When reaching the end user, an attempt is made to page the user via the associated MSC.

However, MSC has no evolution path in the 3rd Generation Partnership Project (3GPP) specifications. Most of them have been online for more than 10 years. They occupy a lot of energy consumption and computer room space, and the equipment failure rate continues to increase. Operator equipment operation and maintenance work brings huge security risks.

Moreover, the current 4G wireless network has achieved continuous coverage and has exceeded the coverage of the second generation communication technology (2G for short). There is basically no scenario in the existing network where the user cannot be paged by IMS and then paging through the MSC in the 2G network. In this way Attaching the VOLTE terminal to the MSC will result in extremely low user data utilization on the MSC. However, VoLTE users within the operator account for a large proportion of the total users. Due to joint attachment, these users will occupy MSC resources, resulting in high equipment utilization. Therefore, in order to avoid the problem of low user data rate on the MSC due to high equipment utilization of user data on the MSC, it is urgent to find a method to turn off the joint attachment of VoLTE users to the MSC in related technologies.

In related technologies, there are the following two ways to turn off the joint attachment of VoLTE users to the MSC.

1. Regularly clear the MSC addresses of registered VoLTE users on the information management unit (Unified Data Management, UDM) side. However, this solution cannot achieve the effect of clearing MSC addresses in real time and reducing MSC resource occupation. Moreover, during the interval between clearing MSC addresses twice, due to scenarios such as cutover and restart, a large number of users will register at the same time to occupy MSC resources. This can cause the MSC to be overloaded.

2. Restrict users from registering MSC addresses on the UDM side and restrict joint registration. There are two problems with this solution: 1) Once the target user signs a contract, when the target user is located in an area with only 2G coverage, or the terminal turns off the VoLTE switch, the terminal will not be able to register with the network and use network services. 2) After restricting joint registration, the MSC will notify the MME, and the MME will notify the user terminal that only the single domain (PS domain) registration is successful. Different terminal modules respond differently to error cause values. Some terminals will repeatedly initiate joint attachment at certain intervals, resulting in a large number of signaling interactions at the interface between the MSC and the MME and the interface between the MSC and the UDM, thereby increasing the network load. Some terminals will even reselect 2G, which affects the user's online experience. In this way, some terminals will repeatedly switch between 2G and 4G networks, which not only affects user perception, but also increases network load.

In response to this, by querying the first user subscription information corresponding to the user on the UDM side of the user subscription information management unit when receiving the attach request forwarded by the base station, wherein the attach request is sent by the terminal corresponding to the user to the base station; when the first user subscription information contains the name of the access point of the fourth generation communication technology Internet Protocol Multimedia Subsystem, and the attachment request meets the preset conditions, the control is no longer directed to the mobile switching center MSC. Send a joint attach request; wherein the preset condition is that the attach request indicates that the terminal supports the long-term evolution voice bearer VOLTE function and indicates that the VOLTE switch of the terminal is turned on, and the type of the attach request is the joint Attach request, this application can not only control the user's corresponding first user subscription information when the user's corresponding first user subscription information contains the fourth generation communication technology Internet protocol multimedia subsystem access point name, and the attachment request satisfies the preset conditions. The terminal no longer sends a joint attachment request to the MSC, so that the terminal can no longer jointly attach to the MSC, so as to solve the problem in related technologies that urgently needs to find a method to turn off the joint attachment of VoLTE users to the MSC; this application can also avoid the above-mentioned method 1 due to regular The UDM side clears the MSC address of the registered VoLTE user, causing the MSC overload problem; further, since the solution of this application is to close the jointly attached MSC when the IMS domain can page the terminal user, the terminal cannot be paged in the IMS domain. The user does not close the joint attachment to the MSC, so this application can avoid a series of problems caused by the above method 2 (restricting the user from registering the MSC address on the UDM side).

The method, device, electronic device and storage medium for sending a terminal attachment request provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios.

Figure 1 shows a method for sending a terminal attachment request provided by an embodiment of the present invention. The method can be executed by the above-mentioned MME. The method includes the following steps:

Step 101: Upon receiving the attach request forwarded by the base station, query the first user subscription information corresponding to the user on the UDM side of the user subscription information management unit.

Wherein, the attachment request is sent to the base station by a terminal corresponding to the user.

Optionally, the base station can be a 4G base station, a 5G base station, or a 3G base station, which is not specifically limited here.

Specifically, the first user's contract information may be pre-signed before the user accesses the network.

Step 102: When the first user subscription information includes the access point name of the fourth generation communication technology Internet Protocol Multimedia Subsystem, and the attachment request meets the preset conditions, control no longer sends the joint request to the mobile switching center MSC. Attach request.

Wherein, the preset condition is that the attach request indicates that the terminal supports the Long Term Evolution voice bearer VOLTE function and indicates that the VOLTE switch of the terminal is turned on, and the type of the attach request is the joint attach request.

It can be understood that when the first user subscription information corresponding to the user includes the fourth generation communication technology Internet Protocol Multimedia Subsystem access point name, the terminal corresponding to the user can access the IMS domain.

In this way, upon receiving the attach request forwarded by the base station, the user subscription information management unit is queried for the first user subscription information corresponding to the user on the UDM side, wherein the attach request is sent by the terminal corresponding to the user. The base station; when the first user subscription information includes the fourth generation communication technology Internet protocol multimedia subsystem access point name and the attachment request meets the preset conditions, the control is no longer sent to the mobile switching center MSC. Joint attach request; wherein the preset condition is that the attach request indicates that the terminal supports the long-term evolution voice bearer VOLTE function and indicates that the VOLTE switch of the terminal is turned on, and the type of the attach request is the joint attach request. request, this application can not only control the terminal corresponding to the user when the first user subscription information corresponding to the user contains the access point name of the fourth generation communication technology Internet protocol multimedia subsystem, and the attachment request meets the preset conditions. The joint attachment request is no longer sent to the MSC, so that the terminal can no longer jointly attach to the MSC, so as to solve the problem in the related technology that it is urgent to find a method to turn off the joint attachment of the VoLTE user to the MSC; this application can also avoid the problem in the related technology due to regular UDM The problem of MSC overload caused by side clearing the MSC address of registered VoLTE users; further, since the solution of this application is to close the jointly attached MSC when the IMS domain can page the terminal user, the terminal user cannot be paged in the IMS domain. The joint attachment to the MSC is not closed at this time, so this application can avoid a series of problems caused by restricting users from registering MSC addresses on the UDM side in related technologies.

In an optional implementation, the attach request is an attach request used to request the terminal to perform initial network registration;

The control no longer sends a joint attachment request to the MSC, including:

Receive the updated second user subscription information corresponding to the UDM;

In the case where the updated second user subscription information contains the VOLTE Internet Protocol Multimedia Subsystem access point name IMS APN, the control no longer sends a joint attachment request to the MSC during the registration process of the Internet Protocol Multimedia Subsystem domain. .

As a specific example, for example, the user's corresponding terminal can send an attachment request for initial network registration to the base station, and the base station can forward the request to the MME; after receiving the request, the MME can initiate a location update request to the UDM and query the UDM side whether the first user subscription information corresponding to the user contains the 4G IMS access point name (APN); if the first user subscription information contains the 4G IMS APN, the above attachment request can indicate the above terminal For a terminal that supports VOLTE and turns on the VOLTE switch, and the attachment request is a joint attachment request (that is, the terminal requests joint attachment to the MSC), the MME can continue to wait for the updated second user subscription information from the UDM side. If the second user signs If the information contains VOLTE IMS APN, then the user has already registered the network on the UDM side; in this way, after the location update process from the MME to the UDM is completed, the MME can return the attach request reception message to the terminal. In this way, the terminal receives After receiving this message, in the subsequent registration process of the IMS domain, joint attachment requests will no longer be frequently initiated to the MSC.

In this way, when the terminal corresponding to the VOLTE user registers with the network, this implementation can control the terminal not to initiate a joint attach request to the MSC if the VOLTE user and its corresponding terminal meet the conditions, thereby preventing the VOLTE user from registering with the network. A series of problems caused by the need to jointly attach MSC (such as a series of problems caused by VOLTE jointly attaching MSC in related technologies).

In an optional implementation manner, the attachment request is an attachment request for the user terminal to request location update.

As a specific example, for example, a cross-tracking area code (TAC) location change occurs at the user terminal location, and the terminal finds that the current tracking area identifier (Tracking Area Identity, TAI) is not in the tracking area of the network where the terminal is registered. (Tracking Area, TA) List (TA table), the user's corresponding terminal can send an attachment request to the base station to request terminal location update, and the base station can forward the request to the MME; after receiving the request, the MME can Initiate a location update request to UDM, and query the UDM side whether the first user subscription information corresponding to the user contains 4G IMS APN; if the first user subscription information contains 4G IMS APN, the above attachment request can indicate that the above terminal supports VOLTE. And the terminal with the VOLTE switch turned on, and the attachment request is a joint attachment request (that is, the terminal requests joint attachment to the MSC), then after the location update process from the MME to the UDM is completed, the MME can return the attachment request received message to the terminal, so , after receiving this message, the terminal will no longer frequently initiate joint attachment requests to the MSC during the subsequent registration process of the IMS domain.

In this way, when the terminal corresponding to the VOLTE user performs location update, if the VOLTE user and its corresponding terminal meet the conditions, this implementation can control the terminal not to initiate a joint attachment request to the MSC, thereby preventing the VOLTE user from performing network registration. A series of problems caused by the need to jointly attach MSC (such as a series of problems caused by VOLTE jointly attaching MSC in related technologies).

Optionally, the attach request includes the usage setting parameter UE's usage setting of the terminal, and the usage setting parameter UE's usage setting carries the VOICE CENTREX parameter of the voice centralized user exchange and the voice domain priority of the evolved wireless access network. level parameters;

The VOICE CENTREX is used to indicate that the terminal supports the VOLTE function, and the Voice domain preference for E-UTRAN parameter of the evolved radio access network is used to indicate that the terminal turns on the VOLTE switch.

Optionally, the Voice domain preference for E-UTRAN parameters of the evolved radio access network can include the PREFENCE CS SECONDARY parameter or the IMS PS Voice only parameter, that is, set the PREFENCE CS SECONDARY parameter or the IMS PS Voice only parameter. Any parameter can complete the setting of the voice domain priority parameters of the evolved radio access network.

In this way, the current status of the terminal can be determined by setting different parameters in the attachment request, and the joint attachment of the terminal to the MSC can be closed based on the status of the terminal.

Optionally, a specific embodiment of the present application will be described below with reference to Figure 2 .

Step 201: In the user initial registration scenario, close the user's joint attachment to the MSC.

Specifically, in the user initial registration scenario, if the user's joint attachment to the MSC is not turned off, as shown in Figure 3, the user's corresponding terminal (UE) can send an attachment request for initial network registration to the base station (eNB) ( AttachRequest), the base station can forward the request to the MME; after receiving the request, the MME initiates the location update process (S6a-Update Location Request and S6a-Update Location Accept) to the UDM, and at the same time initiates a request to the MSC connected to the Sgs interface. Location update process (i.e. Sgs-Update Location Request and Sgs-Update LocationAccept), MSC (referred to as MSS in the figure, i.e. MSC Server) sends the location update process to UDM (i.e. Update Location Request and Update Location Accept); After completing the location update process, the MME sends a reply message to the attachment request (ie, Attach Accept) to the terminal. After receiving the message, the terminal sends an attachment completion message (Attach Complete) to the MME.

If it is necessary to close the user's joint attachment to the MSC, the user's corresponding terminal can send an attachment request for initial network registration to the base station, and the base station can forward the request to the MME; after receiving the request, the MME can initiate a location request to the UDM Update request, and query the UDM side whether the first user subscription information corresponding to the user contains 4G IMSAPN; if the first user subscription information contains 4G IMS APN, the above attachment request can indicate that the above terminal supports VOLTE and turns on the VOLTE switch. terminal, and the attachment request is a joint attachment request (that is, the terminal requests joint attachment to the MSC), then the MME can continue to wait for the updated second user subscription information from the UDM side. If the second user subscription information contains VOLTE IMS APN, then this At that time, the user has already registered the network on the UDM side; in this way, after the location update process from the MME to the UDM is completed, the MME can return the attachment request reception message to the terminal. In this way, after the terminal receives the message, it will perform the following IMS During the domain registration process, joint attachment requests are no longer frequently initiated to the MSC.

Step 202: In the scenario where the user requests location update, close the user's jointly attached MSC.

Specifically, in the scenario where the user requests a location update, if the user's joint attachment to the MSC is not turned off, as shown in Figure 4, the user's corresponding terminal (UE) can send a request for location update (Tracking AreaUpdate) to the base station (eNB). Request), the base station can forward the request to the MME; after receiving the request, the MME initiates the location update process (S6a-Update Location Request and S6a-Update Location Accept) to the UDM, and at the same time initiates a connection to the Sgs interface The location update process (i.e., Sgs-UpdateLocation Request and Sgs-Update Location Accept) of the MSC (referred to as MSS in the figure), and sends the location update process from the MSC to the UDM (i.e., Update Location Request and Update Location Accept); complete the location After the update process, the MME sends a reply message to the terminal requesting a location update request (i.e., Tracking Area Update Accept). After receiving the message, the terminal sends a message requesting the location update completion (Tracking Area Update Complete) to the MME.

If it is necessary to turn off the user's joint attachment to the MSC, the user's corresponding terminal can send an attachment request to the base station to request terminal location update (at this time, it can be assumed that the user has completed the initial network registration, that is, the user has established a 4GIMS APN bearer), and the base station can Forward the request to the MME; after receiving the request, the MME can initiate a location update request to the UDM, if the above attachment request can indicate that the above terminal is a terminal that supports VOLTE and turns on the VOLTE switch, and the attachment request is a joint attachment request ( That is, the terminal requests joint attachment to the MSC), after the location update process from the MME to the UDM is completed, the MME can return the attach request reception message to the terminal. In this way, after the terminal receives the message, it will perform the subsequent IMS domain registration process. , no longer frequently initiate joint attachment requests to the MSC.

In this way, this embodiment can not only control the user's corresponding first user subscription information when the fourth generation communication technology Internet protocol multimedia subsystem access point name is included, and the attachment request satisfies the preset conditions. The terminal no longer sends a joint attachment request to the MSC, so that the terminal can no longer jointly attach to the MSC, so as to solve the problem in the related technology that it is urgent to find a method to turn off the joint attachment of the VoLTE user to the MSC; this embodiment can also avoid the problem in the related technology due to regular The problem of MSC overload caused by clearing the MSC address of registered VoLTE users on the UDM side; further, since the solution of this embodiment is to close the jointly attached MSC when the IMS domain can page to the end user, paging in the IMS domain cannot The joint attachment to the MSC is not closed when reaching the end user. Therefore, this embodiment can avoid a series of problems caused by restricting users from registering MSC addresses on the UDM side in related technologies.
