Description

Method for realizing mobile management of fixed terminal in communication network

The present invention relates to the field of communication technologies, and in particular, to a method for implementing mobile management on a fixed terminal in a communication network. Background technique

In a mobile communication network, mobile user information is centrally managed through a unified HLR (location home register), thereby achieving mobile management of mobile terminals. At the same time, the HLR also serves as the authentication center for mobile users, as an entity that stores data used by mobile users for authentication and encryption. It is precisely because the home location information of mobile users is saved in the HLR, which enables the mobile communication network to realize the mobility of terminals, and effectively shields the differences in the capabilities of end office services to provide uniform services for the network.

However, in the fixed communication network, the user's authority data and new service data are stored in the end office switch, and the end office directly accesses the database of the office to obtain the corresponding information and complete the related call processing functions. Therefore, the user number must be bound to the end office, that is, the data is bound to the end office, and users cannot roam on the local network and cross-office migration. At the same time, the services are provided by the end office, and there are many types of end office models. The service provision capabilities of each end office model are different, so it is difficult to provide or promote unified services across the entire network in the existing fixed communication network; and the data storage method in the fixed communication network also brings intelligent services at the end Bureau difficult to trigger issues.

Although, in the existing mobile communication network, it has a unified location attribution register. (HLR), as a database for centrally managing mobile user information, and as an authentication center for mobile users, it stores data used by mobile users for authentication and encryption. However, as shown in FIG. 1, the mobile switching center MSC and the HLR are connected through a MAP (mobile application part), and the user's location information and new service information are stored in the HLR. The mobile switching center MSC and the mobile gateway office GMSC communicate with the GMSC through the MAP protocol. The HLR interacts to obtain the user's location information and new service information, and completes the user's basic calling functions. Obviously, since the mobile HLR is positioned to serve the mobile communication network, it is connected to the mobile switching center through the MAP protocol. MAP protocol is a mobile communication network protocol. None of the fixed network switches support the above protocols, so it cannot be applied to fixed communication networks.

In the fixed communication network, the intelligent service without the access code is triggered by the end office. The calling intelligent service needs to be triggered by the calling end office. The intelligent service on the calling side, such as a fixed prepaid service, is triggered by the calling end office inserting an access code before the called number and sending it to the SSP. (Service switching node) for service triggering; however, there are currently many types of network end office switches that cannot automatically insert an access code in front of the called number, so it is difficult to implement the above-mentioned service triggering. The called type intelligent service is triggered by the called end office. The called side's intelligent service may include tolling service, color ring back tone service, ONLY service, and wide area CENTREX (central office exchange service). The simultaneous ringing service means that a user can register a certain number of simultaneous ringing numbers. When the user has an incoming call, all the simultaneous ringing numbers can ring simultaneously or sequentially, in order to find the called user in time; It means that fixed network users can customize various signal tones during the call connection phase of the phone. For example, when the caller hears the ringback tone during the ringing phase, they can customize various voices instead of the ringback tone, so that the caller user can listen Voice; The One Number Connect service, that is, the universal personal number means that the user has a personal Number, when a user roams, register by dialing, so that calls to the personal number will be automatically connected to the registered number; the wide-area CENTREX refers to virtualizing a group of users on a fixed network switch into a user group. You can dial each other within the short number to realize the function of the subscriber switch.

That is, the trigger of the intelligent service on the called side is that the landing end office (that is, the called end office) inserts the access in front of the called number and sends it to the SSP (service switching node) for service triggering. Reconnect the call to the end office; however, the called end office usually cannot connect the call to the SSP. Even if the called end office connects the call to the SSP, the SSP needs to reconnect the call to the end office after completing the service processing. The landing end office triggers the call to the SSP, which causes the call to be triggered in a loop, wastes speech, and may cause the call to fail to land. Therefore, the prior art cannot prevent the call from triggering the SSP again. Summary of the invention

In view of the problems existing in the foregoing prior art, an object of the present invention is to provide a method for implementing mobile management on a fixed terminal in a communication network, so that a fixed user terminal in the fixed communication network can implement local network roaming and cross-office migration, etc Business functions.

The integrated home location register is interconnected with the PSTN, PLMN, 3G, and PHS networks, that is, the switches of each network exchange data with the integrated home location register, and the integrated home location register is also shared with the SCP (service control point) data.

The data exchange between the switches of each network and the integrated home location register is as follows: the switches of each network and the integrated home location register pass an ISUP (Integrated Business Service Network User Part) interface, an INAP (intelligent network application protocol) -based interface, and MAP (Mobile Application Part) interface for data exchange.

The step B includes: B1. The fixed user terminal in the fixed communication network initiates a call to the switch;

B2. The switch connects the call to an integrated home location register;

In addition, in the present invention, the intelligent service on the called side is uniformly triggered by the calling end office after querying the HLR, thereby avoiding the problem that the called end office triggers multiple triggers to the SSP.

The core idea of the present invention is to establish a home location register for the fixed user terminal to centrally store and manage user information of the user terminal in the fixed communication network, that is, a comprehensive H LR. The user information includes routing information of the user and subscription information of the intelligent service. Therefore, the user terminal of the fixed communication network has the characteristics of the user terminal of the mobile communication network, such as roaming, migration without changing numbers between offices, etc., and the problem of triggering intelligent services of the entire network can be solved through the HLR. At the same time, the integrated HLR can also be used as a home location register for PHS networks, PLMN networks, and 3G networks, providing fixed and mobile services for future integrated operators. Mobile communication network convergence services.

In the present invention, first, a centralized database is provided for a fixed user terminal, that is, a comprehensive database

HLR, which is used to store user routing information and service subscription information to enable fixed users to roam across offices, while providing unified services for fixed users; secondly, the centralized database for fixed user terminals is compatible with mobile HLR functions at the same time It becomes a comprehensive HLR, that is, it provides a unified database for PSTN, PHS, PLMN, and 3G networks at the same time, which is used to save routing information and corresponding service contract information for mobile and fixed users. The service contract information can be: user Real number, fixed prepaid service contract information, ringing service contract information, CRBT service contract information, ONLY service contract information, wide area CENTREX (central office exchange service) contract information, etc., so that it can develop fixed and mobile communication networks Integrated mixed numbering service, integrated CENTREX (central office exchange service), intelligent network-wide triggering and other related services; Finally, the integrated HLR also provides ISUP (ISDN user part) interface based on fixed communication network, INAP (intelligent network application) (Procedure) signaling interface, through I The SUP and INAP protocols directly interface with switches in the fixed communication network. In addition, the integrated HLR provides a mobile network-based MAP signaling interface to communicate with the PHS network and 3G network, so that the data stored in the integrated HLR can be shared with the SCP (Service Control Point) of the intelligent network to facilitate the development of corresponding intelligent services. To implement the whole network triggering of intelligent services.

In the present invention, all calls are first sent to the integrated HLR, the real number of the user terminal is obtained at the integrated HLR, and the connection processing of the call is performed according to the real number. Therefore, the present invention can implement mixed number allocation, fixed network NP (number flow), and full network triggering of intelligent services. The mixed numbering refers to the unified management of user numbers in the communication network. Each user will have two numbers, one is a logical number that is publicly announced (such as a mobile phone number held by a mobile user), and one is a decision. The physical number of the user's home location can be migrated and changed across offices as required, but the logical number remains unchanged. Due to the existence of the integrated HLR, the user number issued for each user can be compiled and issued according to actual needs, such as Not only can mixed numbering be implemented between fixed users, but also between fixed and mobile users. At the same time, it also realizes the function of fixed network NP, that is, the user number of the fixed communication network is no longer limited to a fixed physical location. It can be used like a mobile user. When the physical location is changed, the user number held remains unchanged, and communication services can be normally carried out, which greatly facilitates the application of a communication network to a fixed user terminal.

The implementation process of the whole network triggering of the intelligent service is as follows: the intelligent service subscription information of the user is stored in the integrated HLR, and for the call of the user with intelligent service permission, the integrated HLR automatically analyzes the intelligent service subscription information and then The corresponding intelligent service access code is inserted before the number, and the call is routed to the SSP (Service Switching Point) to complete the trigger of the corresponding intelligent service. Therefore, the intelligent services on the called side in the present invention are all triggered by the calling end office querying the integrated HLR in a unified manner, thereby avoiding the possibility that the called end office may trigger the SSP multiple times in the existing intelligent service triggering. The problem that the call cannot land.

The foregoing briefly describes the present invention, and a specific implementation of the method according to the present invention will now be described with reference to the accompanying drawings. As shown in FIG. 3, it specifically includes the following steps:

Step 31: Establish an integrated home location register (ie, an integrated HLR), where the integrated HLR stores user information of user terminals of each network, including the user's route Information, business contract information, etc .;

Each network includes a fixed communication network and a mobile communication network. Specifically, the networks can be: PSTN, PLMN, 3G, and PHS networks, etc .:

Step 32: The integrated HLR is separately connected to the PSTN, PLMN, 3G, and PHS networks, that is, the switches of each network perform information interaction with the integrated HLR to obtain user information of the corresponding user terminal. The obtained user information may be Is the user's real number, intelligent service access number, etc .;

Step 33: The switch of each network completes the connection processing of the corresponding call according to the obtained user information of the user terminal.

In the present invention, the fixed communication network can implement the above service processing process by using two schemes: a scheme based on ISUP signaling and a scheme based on INAP signaling.

The service processing flow based on ISUP signaling is shown in Figure 4, which specifically includes the following steps:

Step 41: The calling user of end office 1 (the end office where the calling user is located) initiates a call and sends the call to the integrated HLR, that is, sends an IAM (initial address message) to the integrated HLR; Step 42: the integrated HLR performs the main call After querying and analyzing the calling number, if the calling user has registered the corresponding service and needs to change the calling number, then the changed calling number is returned to the exchange of end office 1 through ACM (address full message);

Step 43: After the integrated HLR performs the called number query and analysis at the same time, if the call originating user has registered the corresponding service and needs to perform the called number conversion, it also sends the release of the end office and the integrated HLR to the end office through a REL (release message) And return the called number after conversion, so that the end office switch can use the REL message to re-call the called number. Number analysis and rerouting;

Step 44: After receiving the REL message, end office 1 sends an RLC (release completion message) to the HLR, and removes the relay circuit connecting end office 1 to the integrated HLR;

Step 45: The end office 1 switch sends IAM to the end office 2 (the end office where the called user is located) according to the information obtained from the integrated HLR;

Step 46: After receiving the IAM from end office 1, end office 2 returns ACM to end office 1. The end office re-initiates a new call based on the calling and called numbers returned by the HLR. The specific call processing process is exactly the same as in the prior art, except that the calling and called numbers based on it have changed.

The INAP signaling-based service processing flow is shown in Figure 5, which includes the following steps:

Step 51: In the fixed network end office, for the call initiated by the user and the corresponding intelligent service is triggered through the SSP, the SSP reports the calling and called numbers to the integrated HLR through InitialDP (starting detection point);

Step 52: Configure the corresponding event detection point for the integrated HLR, and request the SSP to report the detected corresponding monitoring point event to the integrated HLR;

Step 53: The integrated HLR sends a connection operation to the SSP;

Step 54: The SSP reports to the integrated HLR after detecting the corresponding monitoring point event. For example, the SSP reports to the integrated HLR after the monitoring point event such as the call test call is collected, or the information is collected or analyzed.

Step 55: The integrated HLR removes the corresponding connection through the SSP after receiving the reported monitoring point event. If none of steps 52, 54, and 55 are performed, the connection operation in step 53 is issued to the SSP through the integrated HLR to end the dialog operation.

The setting of the integrated HLR in the present invention can also implement integrated services in fixed and mobile communication networks. The integrated services are to consolidate fixed and mobile users into a virtual user group, and implement various methods in the user group. Call processing, including integrated CENTREX, fixed and mobile communication network users mixed numbering, PHS users (such as PHS users) without changing the number of migration to 3G users and so on. The following description is based on an example where a user of a fixed switching office initiates a call to a user of a mobile communication network. The specific service process is shown in FIG. 6 and includes the following steps:

Step 61: LS (fixed network end office), MS (tandem office), GW (gateway office),

Fixed exchanges such as TS (Toll Office) forward the call to the integrated HLR through IAM. That is, when a user initiates a call in a communication network, the exchange first delivers the call to the integrated HLR. The IAM carries the DN of the called user (mobile subscriber number). );

Step 62: The integrated HLR sends a PRN (Request for Roaming Number) request to the mobile end office VMSC (Virtual Mobile Switching Center).

Step 63: The mobile end office VMSC sends a response to the PRN request to the integrated HLR, and the mobile roaming number is provided in the response;

Step 64: The integrated HLR sends the obtained mobile roaming number to the fixed exchange office such as a fixed end office, a tandem office, a gateway office, or a long distance office through a REL message;

Step 65: The fixed switching office sends an IAM message to the GMSC (mobile gateway office), where the message carries the obtained mobile roaming number of the called user;

Step 66: The GMSC routes the call to the VMSC through an IAM message, and the VMSC Follow-up call processing is performed, and the specific call processing process is completely the same as the prior art. The implementation of the present invention enables the fixed communication network to have a centralized database like a mobile communication network, that is, an integrated HLR, and the existence of the integrated HLR can effectively shield the difference in the ability of each end office service to provide unified services for fixed network users. . As a result, the fixed communication network also has the service characteristics of the mobile communication network, that is, users of the fixed communication network can also implement cross-office migration without changing the number like users of the mobile communication network; moreover, due to the setting of the integrated HLR, It can also realize the combination of fixed users and mobile users to carry out fixed-mobile mixed numbering, PHS users to migrate to the 3G network without changing numbers, integrated services such as CENTREX, full-network triggering of intelligent services, and other services.

The above are only the preferred embodiments of the present invention, but the protection scope of the present invention is not limited to this. Any person skilled in the art can easily think of changes or changes within the technical scope disclosed by the present invention. Replacement should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
