Background
In the related art, since the 4G base station cannot be continuously covered in the early development stage of the fourth generation communication technology (4G for short), there is a phenomenon that the internet protocol multimedia subsystem ((Internet Protocol, IP) Multimedia Subsystem, IMS) domain cannot page the end user when the Voice over Long-Term Evolution (VOLTE) terminal performs network registration or location update. To cope with the above phenomenon, the VOLTE terminal initiates a joint attach request in the related art, and the joint attach is performed on a mobility management entity (Mobility Management Entity, MME) and a mobile switching center (Mobile Switch Center, MSC), so that when the IMS domain fails to page the terminal user, the paging user is attempted through the joint attached MSC.
However, MSCs have no evolution route in the third generation partnership project (3rd Generation Partnership Project,3GPP) specification, mostly over 10 years of network time, they occupy a lot of energy consumption and machine room space, and the failure rate of equipment is continuously increasing, which brings a huge security risk to the operation and maintenance work of operators' equipment.
In addition, the current 4G wireless network has realized continuous coverage, and has exceeded the coverage of the second generation communication technology (abbreviated as 2G), and the current network basically does not have the scene that the IMS can not page the user and then pages through the MSC in the 2G network, so that attaching the VOLTE terminal to the MSC can cause extremely low user data utilization rate on the MSC. But the VoLTE users in the operators occupy a larger proportion of the total users, and the partial users occupy the resources of the MSC due to joint attachment, so that the utilization rate of the equipment is high. Therefore, in order to avoid the problem that the device utilization of the user data on the MSC is high, so that the user data rate on the MSC is low, a method for closing the VoLTE user co-attachment MSC is needed in the related art.

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.
Specifically, in the related art, since the 4G base station cannot be continuously covered in the early development stage of the fourth generation communication technology (4G for short), there is a phenomenon that the internet protocol multimedia subsystem ((Internet Protocol, IP) Multimedia Subsystem, IMS) domain cannot page the end user when the Voice over Long-Term Evolution (VOLTE) terminal performs network registration or location update. To cope with the above phenomenon, the VOLTE terminal initiates a joint attach request in the related art, and the joint attach is performed on a mobility management entity (Mobility Management Entity, MME) and a mobile switching center (Mobile Switch Center, MSC), so that when the IMS domain fails to page the terminal user, the paging user is attempted through the joint attached MSC.
However, MSCs have no evolution route in the third generation partnership project (3rd Generation Partnership Project,3GPP) specification, mostly over 10 years of network time, they occupy a lot of energy consumption and machine room space, and the failure rate of equipment is continuously increasing, which brings a huge security risk to the operation and maintenance work of operators' equipment.
In addition, the current 4G wireless network has realized continuous coverage, and has exceeded the coverage of the second generation communication technology (abbreviated as 2G), and the current network basically does not have the scene that the IMS can not page the user and then pages through the MSC in the 2G network, so that attaching the VOLTE terminal to the MSC can cause extremely low user data utilization rate on the MSC. But the VoLTE users in the operators occupy a larger proportion of the total users, and the partial users occupy the resources of the MSC due to joint attachment, so that the utilization rate of the equipment is high. Therefore, in order to avoid the problem that the device utilization of the user data on the MSC is high, so that the user data rate on the MSC is low, a method for closing the VoLTE user co-attachment MSC is needed in the related art.
In the related art, there are two ways to turn off the joint attachment of VoLTE users to the MSC.
1. The MSC addresses of registered VoLTE subscribers are periodically cleared on the side of the information management unit (Unified Data Management, UDM). However, the scheme cannot achieve the effects of clearing the MSC address in real time and reducing the occupation of MSC resources, and in the intermittent period of clearing the MSC address twice, a large number of users can simultaneously register to occupy the MSC resources due to the occurrence of scenes such as cut-over restarting and the like, which can cause overload of the MSC.
2. Limiting the subscriber registration MSC address on the UDM side, limiting the co-registration. There are two problems with this approach: 1) Once the target user signs up, when the target user is located in an area with only 2G coverage, or the terminal turns off the VoLTE switch, the terminal cannot register the network and cannot use network services. 2) After restricting the joint registration, the MSC notifies the MME, and the MME notifies the user terminal that only single domain (PS domain) registration is successful. Different terminal modules react differently to error cause values, and some terminals repeatedly initiate joint attachment at certain intervals, so that a large amount of signaling interaction is generated between an interface between the MSC and the MME and an interface between the MSC and the UDM, and network load is increased. Some terminals even reselect 2G, which affects the user's Internet surfing experience, so that some terminals repeatedly switch between 2G and 4G networks, which affects the user's perception and increases the network load.
In contrast, under the condition that an attachment request forwarded by a base station is received, inquiring first user subscription information corresponding to a user at a user subscription information management Unit (UDM) side, wherein the attachment request is sent to the base station by a terminal corresponding to the user; when the first user subscription information comprises the name of the access point of the fourth-generation communication technology internet protocol multimedia subsystem and the attachment request meets the preset condition, controlling not to send a joint attachment request to the mobile switching center MSC; the application not only can ensure that when the first user subscription information corresponding to the user comprises a fourth-generation communication technology Internet protocol multimedia subsystem access point name and the attachment request meets the preset condition, the terminal corresponding to the user is controlled not to send the joint attachment request to the MSC any more, thereby ensuring that the terminal is not attached to the MSC any more in a joint way, and solving the problem that a method for closing the joint attachment MSC of the VoLTE user is needed to be found in the prior art; the application can also avoid the problem of MSC overload caused by periodically clearing the MSC address of the registered VoLTE user at the UDM side in the mode 1; furthermore, since the scheme of the application is to close the combined attachment MSC when the IMS domain can page the terminal user, and not close the combined attachment to MSC when the IMS domain cannot page the terminal user, a series of problems caused by adopting the mode 2 (limiting the user registration MSC address on the UDM side) can be avoided through the application.
The following describes in detail a method, an apparatus, an electronic device, and a storage medium for sending a terminal attach request according to embodiments of the present application through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
Fig. 1 shows a method for sending a terminal attach request according to an embodiment of the present application, where the method may be performed by the MME, and the method includes the following steps:
step 101: under the condition that an attachment request forwarded by a base station is received, first user subscription information corresponding to a user at a user subscription information management Unit (UDM) side is inquired.
And the attachment request is sent to the base station by the terminal corresponding to the user.
Alternatively, the base station may be a 4G base station, a 5G base station, or a 3G base station, which is not specifically limited herein.
Specifically, the first user subscription information may be pre-signed before the user accesses the network.
Step 102: and under the condition that the first user subscription information comprises the name of the access point of the fourth-generation communication technology Internet protocol multimedia subsystem and the attachment request meets the preset condition, controlling not to send the joint attachment request to the mobile switching center MSC.
The preset condition is that the attachment request indicates that the terminal supports a long term evolution voice bearer VOLTE function, and indicates that a VOLTE switch of the terminal is turned on, and the type of the attachment request is the joint attachment request.
It can be understood that when the first user subscription information corresponding to the user includes the name of the access point of the fourth generation communication technology internet protocol multimedia subsystem, the terminal corresponding to the user can access the IMS domain.
In this way, under the condition that an attachment request forwarded by a base station is received, inquiring first user subscription information corresponding to a user at a user subscription information management Unit (UDM) side, wherein the attachment request is sent to the base station by a terminal corresponding to the user; when the first user subscription information comprises the name of the access point of the fourth-generation communication technology internet protocol multimedia subsystem and the attachment request meets the preset condition, controlling not to send a joint attachment request to the mobile switching center MSC; the application not only can ensure that when the first user subscription information corresponding to the user comprises a fourth-generation communication technology Internet protocol multimedia subsystem access point name and the attachment request meets the preset condition, the terminal corresponding to the user is controlled not to send the joint attachment request to the MSC any more, thereby ensuring that the terminal is not attached to the MSC any more in a joint way, and solving the problem that a method for closing the joint attachment MSC of the VoLTE user is needed to be found in the prior art; the application can also avoid the problem of MSC overload caused by periodically clearing the MSC address of the registered VoLTE user at the UDM side in the related technology; furthermore, because the scheme of the application is to close the combined attachment MSC when the IMS domain can page the terminal user, and not close the combined attachment to the MSC when the IMS domain can not page the terminal user, a series of problems caused by restricting the user registration MSC address on the UDM side in the related technology can be avoided by the application.
In an alternative implementation, the attach request is an attach request for requesting the terminal to perform initial network registration;
the control no longer sends a joint attach request to the MSC, including:
receiving updated second user subscription information corresponding to the UDM;
and under the condition that the updated second user subscription information contains the IMS APN (IP multimedia subsystem access point) of the VOLTE, controlling not to send a joint attachment request to the MSC in the process of registering the Internet protocol multimedia subsystem domain.
As a specific example, for example, a terminal corresponding to a user may send an attach request to a base station for requesting initial network registration, and the base station may forward the request to an MME; after receiving the request, the MME may initiate a location update request to the UDM, and query, to the UDM side, whether the first user subscription information corresponding to the user includes a 4G IMS Access Point Name (APN); if the first user subscription information includes the 4G IMS APN, and the attach request may indicate that the terminal is a terminal supporting VOLTE and turns on a VOLTE switch, and the attach request is a joint attach request (i.e., the terminal requests to be jointly attached to the MSC), the MME may continue waiting for the updated second user subscription information on the UDM side, and if the second user subscription information includes the VOLTE IMS APN, the user has already registered on the UDM side for network registration at this time; in this way, after the location update procedure from the MME to the UDM is completed, the MME may return a message received by the attach request to the terminal, so that after receiving the message, the terminal does not frequently initiate a joint attach request to the MSC in a subsequent IMS domain registration process.
In this way, when the terminal corresponding to the VOLTE user performs network registration, if the VOLTE user and the terminal corresponding to the VOLTE user meet the conditions, the terminal can be controlled not to initiate the joint attachment request to the MSC, so that a series of problems caused by the need of joint attachment of the MSC in the network registration of the VOLTE user (such as a series of problems caused by joint attachment of the VOLTE to the MSC in the related art) can be avoided.
In an alternative implementation, the attach request is an attach request for the user terminal to request a location update.
As a specific example, for example, when the user terminal location changes across Tracking Area code (Tracking Area Code, TAC) Area, and the terminal finds that the current Tracking Area identity (Tracking Area Identity, TAI) is not in a Tracking Area (TA) List (TA table) of the network in which the terminal is registered, the terminal corresponding to the user may send an attach request to the base station for requesting a terminal location update, and the base station may forward the request to the MME; after receiving the request, the MME can initiate a position update request to the UDM and inquire whether the first user subscription information corresponding to the user contains the 4G IMS APN or not to the UDM side; if the first user subscription information includes the 4G IMS APN, and the attach request may indicate that the terminal is a terminal supporting VOLTE and turns on a VOLTE switch, and the attach request is a joint attach request (i.e., the terminal requests joint attach to an MSC), after the location update procedure from the MME to the UDM is completed, the MME may return a message received by the attach request to the terminal, so that after receiving the message, the terminal does not frequently initiate the joint attach request to the MSC in a subsequent IMS domain registration process.
In this way, when the terminal corresponding to the VOLTE user performs location update, if the VOLTE user and the terminal corresponding to the VOLTE user meet the conditions, the terminal can be controlled not to initiate the joint attachment request to the MSC, so that a series of problems caused by the need of joint attachment of the MSC in network registration of the VOLTE user (such as a series of problems caused by joint attachment of the VOLTE to the MSC in the related art) can be avoided.
Optionally, the attachment request includes a usage setting parameter UE's usage setting of the terminal, where the usage setting parameter UE's usage setting carries a VOICE centralized subscriber exchange VOICE center parameter and a VOICE domain priority parameter of an evolved radio access network;
the VOICE domain priority Voice domain preference for E-UTRAN parameter of the evolution radio access network is used for indicating the terminal to open a VOLTE switch.
Optionally, the voice domain priority Voice domain preference for E-UTRAN parameters of the evolved radio access network may include PREFENCE CS second parameter or IMS PS Voice only parameter, that is, setting any one of PREFENCE CS second parameter or IMS PS Voice only parameter may complete the setting of the voice domain priority parameter of the evolved radio access network.
In this way, the current state of the terminal can be determined by setting different parameters in the attach request, and the joint attachment of the terminal to the MSC can be turned off based on the state of the terminal.
Alternatively, a specific embodiment of the present application will be described below with reference to fig. 2.
Step 201: and closing the user joint attachment MSC under the initial registration scene of the user.
Specifically, in the initial user registration scenario, if the user joint attachment MSC is not closed, as shown in fig. 3, the terminal (UE) corresponding to the user may send an Attach Request (Attach Request) for requesting initial network registration to the base station (eNB), and the base station may forward the Request to the MME; after receiving the request, the MME initiates a location update procedure to the UDM (S6 a-Update Location Request and S6a-Update Location Accept), and simultaneously initiates a location update procedure to the MSC connected to the Sgs interface (i.e., sgs-Update Location Request and Sgs-Update Location Accept), and the MSC (denoted by MSS in the figure, i.e., MSC Server) sends the location update procedure to the UDM (i.e., update Location Request and Update Location Accept); after the location update procedure is completed, the MME sends a reply message of the Attach request (i.e., attach Accept) to the terminal, and the terminal sends an Attach Complete message (Attach Complete) to the MME after receiving the message.
If the user joint attachment MSC needs to be closed, the terminal corresponding to the user can send an attachment request for requesting 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 position update request to the UDM and inquire whether the first user subscription information corresponding to the user contains the 4G IMS APN or not to the UDM side; if the first user subscription information includes the 4G IMS APN, and the attach request may indicate that the terminal is a terminal supporting VOLTE and turns on a VOLTE switch, and the attach request is a joint attach request (i.e., the terminal requests to be jointly attached to the MSC), the MME may continue waiting for the updated second user subscription information on the UDM side, and if the second user subscription information includes the VOLTE IMS APN, the user has already registered on the UDM side for network registration at this time; in this way, after the location update procedure from the MME to the UDM is completed, the MME may return a message received by the attach request to the terminal, so that after receiving the message, the terminal does not frequently initiate a joint attach request to the MSC in a subsequent IMS domain registration process.
Step 202: and closing the user joint attachment MSC under the scene of the user request position update.
Specifically, in the scenario where the user requests the location update, if the user joint attachment MSC is not closed, as shown in fig. 4, the terminal (UE) corresponding to the user may send an attachment request for requesting the location update (Tracking Area Update Request) to the base station (eNB), and the base station may forward the request to the MME; after receiving the request, the MME initiates a location update procedure (S6 a-Update Location Request and S6a-Update Location Accept) towards the UDM and at the same time initiates a location update procedure (i.e., sgs-Update Location Request and Sgs-Update Location Accept) towards the MSC (denoted by MSS in the figure) connected to the Sgs interface, and sends the location update procedure from the MSC to the UDM (i.e., update Location Request and Update Location Accept); after the location update procedure is completed, the MME sends a reply message requesting a location update request to the terminal (i.e., tracking Area Update Accept), and the terminal sends a message requesting the location update completion to the MME after receiving the message (Tracking Area Update Complete).
If the user joint attachment MSC needs to be closed, the terminal corresponding to the user can send an attachment request for requesting the terminal position update to the base station (at this time, it can be assumed that the user has completed the primary network registration, that is, the user has established the 4G IMS APN bearer), and the base station can forward the request to the MME; after receiving the request, the MME may initiate a location update request to the UDM, if the attach request may indicate that the terminal is a terminal supporting VOLTE and opens a VOLTE switch, and the attach request is a joint attach request (i.e., the terminal requests joint attach to the MSC), after the location update procedure from the MME to the UDM is completed, the MME may return a message received by the attach request to the terminal, so that, after receiving the message, the terminal does not frequently initiate the joint attach request to the MSC in a subsequent IMS domain registration process.
In this way, the embodiment not only can make the terminal corresponding to the control user no longer send the joint attachment request to the MSC in the case that the first user subscription information corresponding to the user includes the name of the access point of the internet protocol multimedia subsystem of the fourth generation communication technology and the attachment request meets the preset condition, so that the terminal no longer attaches to the MSC in a joint manner, and the problem that a method for closing the joint attachment MSC of the VoLTE user needs to be found in the related art is solved; the embodiment can also avoid the problem of MSC overload caused by periodically clearing the MSC address of the registered VoLTE user on the UDM side in the related technology; further, since the scheme of the embodiment is to close the jointly attached MSC when the IMS domain can page the end user, and not close the jointly attached MSC when the IMS domain cannot page the end user, a series of problems caused by restricting the user registration MSC address on the UDM side in the related art can be avoided by the embodiment.
