Description

Field of Invention

This invention relates to a home location register system, in particular to a home location register system (HLR) for serving a user of several types of networks.

State of the art

In the conditions of rapid economic development of society, the demand for communication services is constantly growing and communication technology is rapidly developing from early systems with spatial separation, analog systems to modern digital systems that meet the requirements of a communication system. In fact, all communication systems require user data management, while currently data management for users of various types of networks is completely separated both physically and logically, for example, data management for public switched telephone networks PSTN, personal telephone systems (PHS) and systems third generation (3G) communications are carried out separately. Thus, the service provider is forced to carry out separate management on various nodes with different service personnel for a user of networks of various types belonging to a single network, and at the same time this user belonging to a single network cannot easily transform the type of user in the network. Therefore, this method of separate management of user data of networks of various types not only requires large labor costs and material consumption, but also harms the business strategy of the service provider associated with user services.

Moreover, in the process of network optimization, regulation of network optimization and change of numbers often occurs. For example, some users who originally belong to the same station number have to be distributed between two or more stations so as not to degrade the quality of user service; in this case, the function of the combined fixed number of the fixed network should be provided. Similarly, with the further development of services, users of the fixed network will be able to register their preferred numbers and own this number after the implementation of the integrated layout; moreover, this number will not be associated with the location of the user, so that the user does not have to change the original number after moving to another place, thus, it is actually possible to move the local number of the fixed network.

Currently, the intellectualization of a fixed network has become a common task, which is receiving more and more attention. One of the most important problems is the resolution of the existing conflict between the rapid development of intelligent services and the full coverage of the network: for example, for call transfer services, the end station cannot activate intelligent services without a connecting code, while it is impossible to make a fixed prepayment; whereas for reception services, such as double ringing and ringing with an individual call waiting signal (“color ring”), since the nature of the services relates to reception, the transmitting station and the intermediate dialing and switching mechanism cannot identify the nature of the service and, therefore, do not can transfer the call to the service switching center (SSP) until the activation and processing of the corresponding service takes place during the call, while the smart reception services for the entire network cannot be implemented. In addition, when converting a fixed network to a 3G network, it is also necessary to take advantage of the existing fixed network for the development of 3G services, including the smooth transformation of a fixed network user into a 3G network user without changing the number and the development of combined fixed network and 3G network services.

In fact, in the prior art, the aforementioned problem cannot be solved and the corresponding requirement cannot be fulfilled, and in a patent search, not a single patent was found that resolved the aforementioned problems.

SUMMARY OF THE INVENTION

The purpose of this invention is to eliminate the disadvantages of separate data management of users of several types of networks, the inconvenience of transferring network number resources and the lack of the use of network intelligent services in the prior art in order to provide a home location register system for servicing a user of several types of networks that can effectively manage network number resources, conveniently carry out network intelligent services and integrate management for network users of several types .

To achieve this goal, the present invention provides a home location register system for servicing several types of network users, comprising a channel-wide signaling processing subsystem, a database subsystem, a service processing subsystem and an operational maintenance subsystem, all of which are connected to a communication network and respectively information exchange; wherein the subsystem for processing a common channel signaling, consisting of one or more modules of the subsystem for processing a common channel signaling, performs the processing function of OKS-7; a database subsystem consisting of one or more data processing modules of the home location register is used to save user data; the service processing subsystem provides a multi-module tariff separation mode and contains one or more modules for processing services of the home location register; the operational maintenance subsystem comprises an operational maintenance server connected to a service reception terminal and a proximal maintenance terminal; a service reception terminal and a near maintenance terminal provide a working platform; at the same time, obtaining information about the operating state of the home location register system, its verification and maintenance is carried out from the near terminal of operational maintenance; user management can be implemented through a terminal receiving services, and operational maintenance can be implemented through a router.

The aforementioned one or more modules of the channel-wide signaling processing subsystem (MOX, (CPM)) are interfaces for communication devices between the home location register system and the core network. The service processing subsystem in the multi-module tariff separation mode consists of one or more service processing modules (MOU) of the home location register (HLR); the number of modules of the MPL register DRM (HLR) can be determined and flexibly applied depending on the user's requirements for throughput; several modules of the MOC provide services and process operations in parallel, providing redundancy for each other, thus, in the event of a failure of any MOC, the other MOCs evenly distribute the load among themselves; MOU uses a high-performance processor to perform service processing, access the real-time database subsystem and exchange information between the processing module in front of the MOX module (CPM) and the switching device of the core network.

The database subsystem also consists of one or more data processing modules (MOD) of the home location register (HLR), used mainly for storing user data.

In the above technical solution, all these subsystems are interconnected via a high-speed Ethernet network and are connected via the Transmission Control Protocol / Internet Protocol TCP / IP. To guarantee reliability, all of the above subsystems are connected by a redundant network.

According to the claimed invention, the home register system of a user service location of several types of networks functions as a central data processing unit in the network, used mainly for unified and integrated management of various types of user data, and performs signal exchange through a channel-wide signaling subsystem and other functional subsystems . With such a home location register system for servicing users of several types of networks, it is possible to perform unified and integrated data management of users of networks of various types and to provide combined PSTN user numbers, a service to activate intelligent services throughout the network and a roaming service for PHS users, to support smooth transformation a PHS / PSTN user into a 3G network user, which not only reduces operating costs for Eider services, but also has a positive effect on attracting new users.

Detailed Description of a Preferred Embodiment

The following is a detailed description of specific embodiments of this invention with reference to the accompanying drawings.

The claimed invention is applicable to a home location registration system (HLR) of mobile communications, which typically includes PSTN, PHS and 3G (third generation) networks, and can support integrated data management of PSTN users, PHS users and 3G users, support combined preset numbers and activation of intelligent services throughout the network for a PSTN user, support roaming services for a PHS user and ensure smooth transformation of a PHS / PSTN user into a 3G user.

Figure 1 according to this invention presents the position of the home location register system (or "integrated DRM (HLR)" in the network; the system, on the one hand, is connected to the PHS network, the PSTN network and the 3G network via the OKS-7 all-channel signaling system so as to satisfy the user's need for various services using the MAP protocol, such as updating the location, establishing call connections, checking credentials, etc .; The PSTN switching device uses the MAP protocol or the user subsystem protocol (ISUP) of a digital network with the integration of ISDN services for the implementation of user combined preset numbers, the activation of intelligent services, etc., and, on the other hand, the system is connected to a single system working services through the Internet Protocol (IP) network to receive various user services, such as opening an account, terminating service, changing a number, etc.

Figure 2 clearly shows the structure of the home location register system according to this invention. This system contains the following subsystems: subsystem 1 for processing the general channel signaling, subsystem 3 for processing services, subsystem 2 for the database, subsystem 4 for operational maintenance, and a high-speed Ethernet network is used to communicate between all the subsystems and coordinate their actions. The following is a detailed description of an example implementation with reference to FIG. 2.

1. Channel 1 subsystem

This subsystem is used to connect and process common channel signaling, and its typical implementation is the function of connecting and processing OKS-7.

In order to integrate the data management of PHS users and PSTN users, the PSTN switching device must be able to support PHS-MAP signaling. Using the PHS-MAP signal, the PSTN user can perform a location management service, an authorization verification service, a call service, a data management service, and the like. in order to implement integrated PSTN user data management in the home location register system, as well as provide mobile services for the PSTN user.

To perform the services of combined preset numbers, to activate the intellectual services of the PSTN user, the switching device in the PSTN network must be able to support 3G-MAP signaling or ISUP signaling. When using 3G-MAP signaling or ISUP signaling, the PSTN switching device can switch the user number, look for the user intelligent service connection code in the DRM (HLR) to perform the services of the combined preset number, activate intelligent services, etc. and to implement integrated data management of the combined preset number and activation of intelligent user service of the PSTN in the home location register system.

In order to integrate the data management of PHS users, PSTN users and 3G users, the channel-wide signaling processing subsystem 1 must distinguish and process the PHS-MAP signaling and the 3G-MAP signaling. Since the PHS-MAP signaling and the 3G-MAP signaling are not fully compatible, there are four processing methods.

(1) Hardware separation: connecting a 3G network device and a PSTN, PHS network device to a home location register system through various subsystems 1 for processing common channel signaling and, accordingly, for processing signaling PHS-MAP and 3G-MAP signaling in various modules of the subsystem for processing common channel signaling MOX (CPM).

(2) Software configuration: classification of the switching devices in the network according to the signaling point or global heading (G3 (GT)) by configuring the data of the home location register system: 3G network device, PHS network device and PSTN network device. After receiving the signaling message of the network device, the network type of this device is determined by configuring data, and then processing is performed using PHS-MAP or 3G-MAP signaling, depending on the network type of this device.

(3) Device subsystem number: since 3G-MAP and PHS-MAP are not currently fully compatible in content, you can use the subsystem number (SSN) to distinguish between them. When the MOX module (CPM) receives signaling messages sent by various networks, the NPS (SSN) of the logical DRM (HLR), the corresponding PHS network and the PSTN network are adjusted; the PHS network, the PSTN network and the 3G network can be distinguished by the NPS (SSN) obtained from the level resolution through the signaling connection control subsystem (SCCP) in order to determine which protocol to use for message processing - PHS-MAP or 3G- MAP.

(4) Application contexts: since 3G-MAP and PHS-MAP are not currently fully compatible in their content, MAP application contexts can be used to distinguish between them. The standard application context is 3G-MAP: MAP-ApplicationContexts {ccitt identified-organization (4) etsi (0) mobileDomain (0) gsm-Network (1) modules (3) map-ApplicationContexts (2) version6 (6)}

(5) In doing so, the PHS-MAP changes the “gsm-Network (1)” label to a different distinguishing value to determine which protocol to accept for message processing, the PHS-MAP protocol or the 3G-MAP protocol.

2. Subsystem 3 processing services

Since the channel-wide signaling processing subsystem 1 has already respectively processed the PHS-MAP message and the 3G-MAP message, the service processing subsystem 3 only needs to accept various processing procedures for processing depending on the type of signals transmitted by the channel-wide signaling processing subsystem 1.

3. Subsystem 2 databases

All types of users share one basic user data table in order to distinguish users of different types of networks according to the type of user. The general characteristic of all users occupies one position in the table, the special characteristic of the user occupies one special position in the table as a whole. All database users, provided that the user number does not change, can change the user type attribute in the main user data table and the corresponding information in the characteristics table in order to replace one type of network user with another type of network user.

4. Subsystem 4 operational maintenance

The operational maintenance subsystem 4 comprises an operational maintenance server (IT) 41, an operational receiving terminal 42, and a proximal maintenance terminal 43; the operational receiving terminal 42 and the near maintenance terminal 43 provide the human-machine operating platform, and the service provider can determine the operating status of the home location system through the near maintenance and maintenance terminal 43 in order to check and repair the failure, and implement control of subscribers through the terminal 42 receiving services. In addition, remote reception of services and operational maintenance can be implemented using a router (s). Using these tools, the operational maintenance subsystem 4 can carry out unified operation and maintenance for the entire home location register system and can carry out unified reception for users of various types of networks depending on the parameters of PHS, PSTN and 3G users' services in order to be able to receive different network users types on one working interface and at the same time switch user types for any user ovatelya.

Industrial applicability

According to the claimed invention, it is possible to simultaneously process the ISUP, PHS-MAP and 3G-MAP signaling within the same home location register system and it is possible to simultaneously control PSTN, PHS and 3G users within the database of one home location register system to provide the combined set number service and the function of activating intelligent ISUP user services and PHS user roaming services, as well as implement unified and integrated user data management TF OP, PHS and 3G, to reduce the cost of equipment for the service provider and the costs of operation and maintenance.

In addition, based on the unified and integrated data management of users of networks of various types, this invention also offers convenient switching of the user type without changing the user number so that the service provider reaches the goal of attracting and retaining customers in the process of network development.

Therefore, the home location register system according to this invention performs unified and integrated data management of PSTN, PSH and 3G users and provides the PSTN user with a combined set number service and activation of intelligent services throughout the network, provides the PHS user with roaming service and smoothly transforms the PHS / PSTN user into 3G user this system and other switching equipment in the core network can exchange information with the mobile communication mechanism, the PHS network switching mechanism and the fixed network switching mechanism by communicating the mobile communication application subsystem (MAP) of another protocol, and can also exchange information with the stationary switching mechanism network through ISUP messages to satisfy various service requests for users of various types of networks. Thus, it is understood that, based on the prior art, those skilled in the art can put into practice the technical solution disclosed in this invention and can obtain the corresponding technical result, therefore, the technical solution provided by this invention fully meets the requirements of industrial applicability .

Finally, it should be noted that the above implementation examples serve only to disclose the technical solution according to this invention, without imposing any restrictions. It will be apparent to those skilled in the art that the invention may be modified or modified without altering the spirit and scope of this invention, encompassed by the scope of the claims of this invention.
