Problems solved by technology

[0005] Second, trigger type issues
[0016] Implementing SHLR requires adding a new signaling message process in ISUP+, and the new process cannot be supported by switching devices in the network at present, so it is necessary to upgrade and modify the signaling software and call processing software of existing devices in the network. The implementation is complex, and the HLR solution based on ISUP+ has a huge impact on call processing, which is caused by the change of the signaling process. These changes greatly increase the processing capacity of the switching equipment, requiring an increase of about 50% in the tandem office Left and right processing capacity, need to increase a lot of equipment investment

Embodiment Construction

[0042] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0043] The present invention realizes the function of SHLR based on the mechanism of call forwarding unconditional (Call Forwarding Unconditional; CFU) service. The CFU mechanism needs to utilize two internal fields: a mobile station ISDN number (Mobile Station ISDN Number; MSISDN) field and a call forwarding destination number (Forward to Number; FTN) field. Table 1 gives an example of the mapping relationship of numbers in the HLR database.

[0044] MSISDN

FTN

[Calling Party Access Code +] Logical Number (DN)

Physical Number (LRN) or Calling Party Access Code

[Called Party Access Code +] Physical Number (LRN)

Logical number (DN) or called party access code

[0045] […] in the table indicate optional items.

[0046] Figure 4 It is an example of the call flow generated between GMSC and HLR after using the CFU mechanism. ...

Abstract

The invention comprises: at least one LAN switch, at least one gateway mobile switch center (GMSC) and at least one home location register (LHR). The interface transmission protocol between the LAN switch and the gateway mobile switch center is ISUP+ signaling, and the interface protocol between the gateway mobile switch center and the home location register is MAP protocol. The gateway mobile switch center comprises a packet processor and a cooperative processor. The data domain in the home location register is used to implement the function of the intelligent home location register; in which, only modification needing to do is to modifying the GP software at ISUP+ interface while no need to modify the MAP signaling and database between GMSC and HLR.

Description

(1) Technical field [0001] The invention relates to a method for realizing the function of an intelligent home location register, especially a method for realizing the function of an intelligent home location register in a traditional telephone switching network. (2) Background technology [0002] Intelligent network is currently a key development direction of China Telecom (CHINA TELECOM; CTC). The so-called intelligent network refers to the transformation of the Public Switched Telephone Network (PSTN) to solve the problem of intelligent services in the fixed network, thereby providing users with richer new intelligent services, such as ring back tones and caller prepaid services. Business, one machine with multiple numbers business, etc. To realize the intelligent network, the following two problems must be solved first. [0003] First, the issue of mixed number allocation. The mixed number allocation service is to transform the original user phone number with both use...
