detailed description

In order to make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the various embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. However, a person of ordinary skill in the art can understand that, in each embodiment of the present disclosure, many technical details are proposed for the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solution claimed in this application can be realized. The following divisions of the various embodiments are for convenience of description, and should not constitute any limitation on the specific implementation of the present disclosure, and the various embodiments may be combined with each other without contradiction.

The first embodiment of the present disclosure relates to a registration method of an IMS terminal. In this embodiment, after the IMS terminal uses the fixed-line number to register to the IMS network, the fixed-line number can be used as the calling or called number to make calls; in practical applications, the IMS fixed-line function can use the software SDK (Software Development Kit, Software development kit) is installed in the smart device, so that the smart device has the capability of an IMS terminal, and the smart device with the capability of the IMS terminal can be regarded as an IMS terminal, such as smart speakers, early education machines, etc. The system and programmable smart devices have the functions of voice recognition and Internet connection, and can also realize the fixed-line function by registering with the IMS network; in this embodiment, the registration method of the IMS terminal is applied to the location information server (Location Information Server (LIS for short) is taken as an example for description. The location information server can be understood as a server with the ability to collect and process information, which can interact with IMS terminals and IMS networks. In this embodiment, it can handle registration initiated by IMS terminals. Request and register with the IMS network as the agent of the IMS terminal. The flowchart of the IMS terminal registration method in this embodiment is shown in Fig. 1, and includes:

Step 101: Receive a registration request initiated by an IMS terminal; where the registration request carries the physical address of the network currently accessed by the IMS terminal and the identification information of the IMS terminal;

Step 102: Acquire the physical address of the network pre-bound with the IMS terminal according to the identification information of the IMS terminal;

Step 103: Determine whether the physical address of the network currently accessed by the IMS terminal is consistent with the physical address of the network pre-bound to the IMS terminal; if yes, go to step 104; if not, end;

Step 104: Initiate registration of the IMS terminal to the IMS network.

The implementation details of the registration method of the IMS terminal in this embodiment will be described in detail below. The following content is only provided for ease of understanding and is not necessary for implementing this solution.

In this embodiment, the registration request of the IMS terminal received by the location information server carries the physical address of the network that the IMS terminal is currently connected to, and the IMS terminal can also be pre-bound according to the identification information of the IMS terminal carried in the registration request. The location information server can determine whether the IMS terminal is registered in the pre-bound network according to whether the physical address of the network currently connected to the IMS terminal is the physical address of the network pre-bound to the IMS terminal And if it is used, it means that the network currently accessed by the IMS terminal is the network pre-bound to the IMS terminal, and the location of the network currently accessed by the IMS terminal is legal, so the location information server initiates the registration of the IMS terminal to the IMS network. It also realizes that the IMS terminal is restricted from registering and using in the pre-bound network; at the same time, the processing of the registration request of the IMS terminal and the restriction on the use location of the IMS terminal are transferred to the location information server for execution, and the IMS network can directly Responding to the registration request sent by the location information server without performing operations such as calculation and analysis processing on the registration request, so that the IMS network side can focus on the processing of the call logic, so as to save the computational resource consumption on the IMS network side and effectively reduce the IMS network side. Work load.

In step 101, the location information server receives the registration request initiated by the IMS terminal; specifically, after the IMS terminal accesses the network (such as accessing the wireless LAN hotspot in the home gateway), it initiates a registration request to the location information server (LIS) ; The registration request carries the identification information of the IMS terminal, and also carries the physical address of the network currently connected to the IMS terminal; among them, the physical address of the network currently connected to the IMS terminal can be collected through the SDK installed in the IMS terminal . In this embodiment, a method for inserting the physical address of the network currently accessed by the IMS terminal collected by the SDK into the registration request initiated by the IMS terminal is provided, which is specifically as follows:

(1) Insert the access network information header field (P-Access-Network-Info header field) in the registration request;

(2) A new network node parameter (lis-i-wlan-node-id) is defined in the access network information header field (P-Access-Network-Info header field). The newly defined parameter is used to carry the current connection of the IMS terminal. The physical address of the incoming network;

In an example, the above method of inserting the physical address of the network currently accessed by the IMS terminal in the registration request may be embodied in the form of code as:

P-Access-Network-Info: IEEE-802.11n;

lis-i-wlan-node-id="UE-AP-MAC-Address"

Among them, "P-Access-Network-Info: IEEE-802.11n" indicates that the access type of the network currently accessed by the IMS terminal is the IEEE-802.11 series (IEEE 802.11 is a standard for wireless LANs nowadays); "lis -i-wlan-node-id="UE-AP-MAC-Address" means that the value passed by the network node parameter is the physical address of the access point when the IMS terminal is currently connected to the network (the access point when the IMS terminal is currently connected to the network) The physical address of the entry point is represented by UE-AP-MAC-Address).

In this embodiment, the P-Access-Network-Info header field is newly inserted in the registration request to avoid occupying the existing header field in the registration request generated by the IMS terminal, that is, to avoid the difference between the existing header field and the existing header field. Domain generates potential conflicts; at the same time, a new parameter lis-i-wlan-node-id is defined in the P-Access-Network-Info header field to transfer the physical address of the access point when the IMS terminal is currently connected to the network, and the new definition The parameters are not the existing parameters that can be recognized by the IMS network side, so the newly defined parameters will only be recognized in the location information server, and will not affect the service processing on the IMS network side; and the location information server can customize the Parameter copy, modify, delete and other operations, such as copy the value passed by the parameter lis-i-wlan-node-id to the existing parameter that can be recognized by the IMS network side, or the parameter lis-i-wlan-node -The value passed by id is mapped to other values and then filled in the existing parameters that can be recognized by the IMS network side, etc., which increases service flexibility; in addition, based on the above method of the physical address of the network currently connected to the IMS terminal, The location information server can further collect other location information by defining and inserting new parameters according to business needs, such as collecting longitude and latitude information of the geographic location of the terminal, home address information corresponding to the network accessed by the terminal, The identification information of the base station where the network is located increases business scalability and lays a certain technical foundation for future business expansion in practical applications.

In step 102, the location information server obtains the physical address of the network pre-bound with the IMS terminal according to the identification information of the IMS terminal; this embodiment provides a way to obtain the physical address of the network pre-bound to the IMS terminal. As a specific implementation of step 102, the specific implementation flowchart of step 102 is shown in Figure 2:

Step 1021: According to the identification information of the IMS terminal, query the broadband account corresponding to the identification information of the IMS terminal from the prestored correspondence between the identification information of the IMS terminal and the broadband account.

Specifically, the location information server prestores the correspondence between the identification information of the IMS terminal and the broadband account; the correspondence between the identification information of the IMS terminal and the broadband account can be determined by the IMS service activation system after confirming that the IMS terminal has activated the IMS service Issued to. In this step, the IMS service activation system is a system set up for users to subscribe to the IMS fixed-line service of the IMS terminal; when users subscribe to the IMS fixed-line service of the IMS terminal through the IMS service activation system, the registered user needs to open the network on the operator side It’s understandable here that the IMS terminal that the user needs to subscribe to the IMS service is to be used in the user-subscribed network, that is, the IMS terminal needs to be pre-bound to the network that the user subscribes to on the operator’s side. ; At the same time, the user also needs to register the IMS terminal that needs to open the IMS service, so that the registered information carries the unique terminal identification code of the IMS terminal; after the user is registered, the IMS service activation system records and stores the terminal identification of the IMS terminal Code, broadband account number, and assign a fixed-line number for IMS fixed-line calls to the IMS terminal, then a one-to-one corresponding IMS terminal’s terminal identification code, fixed-line number and broadband are recorded and stored in the IMS service activation system Account number; in this step, the terminal identification code of the IMS terminal and/or the fixed-line number of the IMS terminal can be used as a unique identifier for the IMS terminal, that is, both can be used as the identification information of the IMS terminal; The corresponding relationship between the identification information of the IMS terminal and the broadband account is recorded and stored in the IMS service activation system. After the IMS service activation system confirms that the IMS terminal has activated the IMS service, the corresponding relationship between the identification information of the IMS terminal and the broadband account is sent to the location information server for the location information server to record and store the corresponding relationship between the identification information of the IMS terminal and the broadband account.

Therefore, the location information server can go to the pre-stored correspondence between the IMS terminal identification information and the broadband account based on the IMS terminal identification information carried in the received registration request initiated by the IMS terminal, and find the corresponding IMS terminal identification information The broadband account can further find out the network opened by the user on the operator side based on the broadband account, that is, the network to which the IMS terminal needs to be bound in advance.

Step 1022: According to the broadband account corresponding to the IMS terminal, obtain the physical address of the network pre-bound to the IMS terminal from the network management system.

Specifically, the corresponding relationship between the broadband account and the physical address of the network is pre-stored in the network management system; in practical applications, the network management system can remotely manage the network opened by the user on the operator side through the TR069 protocol to detect the user side network The status and performance of the user-side network, and the collection of user-side network information, including collecting the physical address of the user-side network. In this step, it can be understood that when the user uses a broadband account to log in to the network opened on the operator side, the network management system records the broadband account used by the user and the physical address of the network where the user logs in with the broadband account, that is, the broadband account is pre-stored Correspondence with the physical address of the network. According to the acquired broadband account corresponding to the IMS terminal, the location information server goes to the corresponding relationship between the broadband account pre-stored in the network management system and the physical address of the network, and finds the physical address of the network corresponding to the broadband account of the IMS terminal; It is to be used in the network opened by the user, that is, the network that the IMS terminal needs to be pre-bound is the network opened by the user on the operator side, so the network corresponding to the broadband account is the network pre-bound to the IMS terminal. The physical address of the network corresponding to the broadband account is the physical address of the network pre-bound to the IMS terminal.

Step 103: The location information server determines whether the physical address of the network currently accessed by the IMS terminal is consistent with the physical address of the network pre-bound to the IMS terminal; if the physical address of the network currently accessed by the IMS terminal is the same as the network pre-bound to the IMS terminal If the physical address of the IMS terminal is consistent, it means that the network currently connected to the IMS terminal is the network pre-bound to the IMS terminal. The location of the network currently connected to the IMS terminal is legal, and the location information server can allow the IMS to register and use it subsequently; If the physical address of the network currently accessed by the IMS terminal is inconsistent with the physical address of the network pre-bound to the IMS terminal, it means that the network currently accessed by the IMS terminal is not a pre-bound network. The registration location of the registration request initiated by the IMS terminal is If it is illegal, the location information server does not respond to the registration request of the IMS terminal, or returns a message rejecting the registration request to the IMS terminal, that is, it refuses the IMS terminal to register and use it in the currently connected network.

Step 104: The location information server initiates registration of the IMS terminal to the IMS network; specifically, after determining that the network currently connected to the IMS terminal is the network pre-bound to the IMS terminal, the location information server can directly initiate the registration of the IMS terminal The registration request is forwarded to the IMS network side, and it can also be used as a proxy for the IMS terminal. The rebuilt registration request is sent to the IMS network side. The rebuilt registration request includes the identification information of the IMS terminal and the physical address of the network currently connected to the IMS terminal (ie The physical address of the network pre-bound to the IMS terminal).

The following is an example to illustrate the registration method of the IMS terminal in this embodiment. The interaction diagram of the registration method of the IMS terminal is shown in Figure 3. In this example, the smart speaker is used as the IMS terminal, and the home broadband is used as the smart speaker. Specify the connected network.

Smart speakers are connected to the home broadband via wireless network (WIFI) for Internet access. The home broadband is managed by the smart home gateway. The smart home gateway can connect the home network and the external network, and at the same time connect and control the networkable devices inside the home; a collection of smart home gateways IEEE 802.11 access point (that is, the WIFI access point of the home broadband network, recorded as WIFI AP), the geographical coverage of WIFI AP can basically cover the geographical range of a family, and its physical address is unique in the world Therefore, when the smart speaker is connected to the home broadband via WIFI for Internet access, the fixed-line SDK in the smart speaker records the address of the WIFI AP (denoted as WIFI AP MAC) (② in Figure 3) as the current network connection of the smart speaker The physical address is recorded as UE AP MAC.

The fixed phone SDK of the smart speaker initiates a registration request to the location information server (LIS). The registration request carries the WIFI AP MAC and the identification information of the smart speaker. The identification information can be the terminal identification code of the smart speaker (denoted as UE ID), And/or the fixed-line number assigned to the smart speaker by the IMS service activation system (denoted as TEL URI) (③ in Figure 3).

The corresponding relationship between the identification information of the smart speaker obtained from the IMS service activation system and the broadband account (denoted as BroadBand ID) of the smart speaker is pre-stored in the LIS (1 in Figure 3); LIS analyzes the received from the fixed-line SDK of the smart speaker For registration request, query the corresponding BroadBand ID according to the UE ID and/or TEL URI carried in the registration request.

The corresponding relationship between the BroadBand ID of the smart home gateway and the physical address of the network is pre-stored in the network management system; LIS uses the queried BroadBand ID as an input parameter to query the network management system for the corresponding physical address of the network. It is to query the physical address of the network pre-bound to the smart speaker; the network management system records the physical address of the network pre-bound to the smart speaker as Home AP MAC, and returns it to LIS (④ in Figure 3).

If LIS judges that the physical address UE AP MAC of the network currently connected to the smart speaker is the same as the physical address Home AP MAC of the network pre-bound to the smart speaker, it means that the home broadband network currently connected to the smart speaker is pre-bound to the smart speaker Therefore, LIS acts as the agent of the smart speaker to initiate a smart speaker registration request to the IMS network side (5 in Figure 3), so that the smart speaker can realize the IMS fixed-line function after successful registration. If LIS judges that the physical address UE AP MAC of the network currently connected to the smart speaker is inconsistent with the physical address Home AP MAC of the network pre-bound to the smart speaker, it means that the home broadband network currently connected to the smart speaker is not pre-bound to the smart speaker Therefore, LIS does not respond to the registration request of the smart speaker or returns a message rejecting the registration request to the smart speaker (6 in Figure 3).

Since the geographic coverage of the WIFI AP mentioned above can basically cover the geographic range of a family, when the smart speaker is restricted from being registered and used in the pre-bound home broadband network, the smart speaker is restricted from being used in a fixed home. Use within the scope, that is, to limit the fixed-line number of a smart speaker to be used in a fixed home, which is in line with the use scenario of fixed-line phones, and avoids the problem of unfixed locations of fixed-line phones.

Compared with related technologies, this embodiment provides a method for registering an IMS terminal: receiving a registration request initiated by the IMS terminal; wherein the registration request carries the physical address of the network currently accessed by the IMS terminal and The identification information of the IMS terminal; obtain the physical address of the network pre-bound with the IMS terminal according to the identification information of the IMS terminal; determine the physical address of the network currently connected to the IMS terminal and the IMS terminal Whether the physical addresses of the pre-bound networks are consistent; if they are consistent, the registration of the IMS terminal is initiated to the IMS network; that is, the received registration request of the IMS terminal carries the information of the network currently connected to the IMS terminal The physical address can also obtain the physical address of the network pre-bound to the IMS terminal according to the identification information of the IMS terminal carried in the registration request, so that it can be compared according to whether the physical address of the network currently connected to the IMS terminal is pre-bound to the IMS terminal. Specify the physical address of the network to determine whether the IMS terminal is registered and used in the pre-bound network. If it is, the network currently connected to the IMS terminal is the network pre-bound to the IMS terminal, and the network currently connected to the IMS terminal The location of the IMS terminal is legal, so the registration of the IMS terminal is initiated to the IMS network, which limits the registration and use of the IMS terminal in the pre-bound network; at the same time, before the registration of the IMS terminal is initiated to the IMS network, The processing of registration requests for IMS terminals and the restriction on the use position of IMS terminals are completed, so that the IMS network does not need to perform operations such as calculation and analysis processing on registration requests, so that the IMS network can focus on the processing of the call logic to save the IMS network side The consumption of computing resources effectively reduces the workload on the IMS network side.

The second embodiment of the present disclosure relates to a method for registering an IMS terminal. This embodiment is roughly the same as the first embodiment. In this embodiment, another method of obtaining the physical address of the network pre-bound to the IMS terminal is provided. In this embodiment, the registration method of the IMS terminal is still applied to the location information server as an example to illustrate the registration method of the IMS terminal. The process of the registration method of the IMS terminal is roughly shown in Figure 1. Detailed description of the process:

Step 101: Receive a registration request initiated by an IMS terminal; where the registration request carries the physical address of the network currently accessed by the IMS terminal and the identification information of the IMS terminal.

Step 102: According to the identification information of the IMS terminal, query the physical address of the network pre-bound with the IMS terminal from the correspondence between the identification information of the IMS terminal and the physical address of the network;

In this step, the corresponding relationship between the identification information of the IMS terminal and the physical address of the network is obtained in the following manner, and the method for obtaining the corresponding relationship between the identification information of the IMS terminal and the physical address of the network is shown as 20 in Figure 4:

Step 201: Periodically obtain the correspondence between the broadband account and the physical address of the network from the network management system;

Step 202: Determine the correspondence between the identification information of the IMS terminal and the physical address of the network according to the correspondence between the broadband account and the physical address of the network and the correspondence between the prestored identification information of the IMS terminal and the broadband account.

Specifically, because the location information server pre-stores the correspondence of "broadband account-identification information of the IMS terminal", the network management system pre-stores the correspondence of “broadband account-the physical address of the network pre-bound to the IMS terminal”. Therefore, the location information server can integrate the two correspondences in advance, that is, the identification information of the IMS terminal corresponding to the same broadband account and the physical address of the pre-bound network are in one-to-one correspondence, thereby determining the "IMS terminal's Identification information—the physical address of the network pre-bound to the IMS terminal. When the location information server parses and obtains the identification information of the IMS terminal, it can be determined according to the “identification information of the IMS terminal—the network address of the IMS terminal pre-bound The corresponding relationship of “physical address” can directly obtain the physical address of the network pre-bound to the IMS terminal without interactive query to the network management system in real time. This saves the time for information exchange and helps to determine the current connection of the IMS terminal more quickly. Whether the connected network is legal.

In practical applications, the location information server can periodically obtain the correspondence between the broadband account and the physical address of the network from the network management system, that is, periodically perform the above-mentioned "identification information of the IMS terminal—the pre-bound network of the IMS terminal" The determination of the corresponding relationship of "physical address" does not affect the normal function of the location information server.

Step 103: Determine whether the physical address of the network currently accessed by the IMS terminal is consistent with the physical address of the network pre-bound to the IMS terminal; if yes, perform step 204; if not, end.

Step 104: Initiate registration of the IMS terminal to the IMS network.

Compared with related technologies, this embodiment also provides a way to obtain the physical address of the network pre-bound to the IMS, that is, periodically obtain from the network management system and store the "broadband account number—the network pre-bound to the IMS terminal.
