Method for managing integrated network locations

Abstract

A method realizing the location management of an integrated network assigns location information for various types of terminals accessing the integrated network and finishes location registration by registering identities and location mapping of the terminals on a mapping server. When a terminal moves, a location update process is initiated toward the mapping server via an access router, and the update of terminal location information in the whole network is finished by means of information interaction among related entities. When a terminal initiates communication, the access router initiates a location query procedure toward the mapping server of the local domain, and by means of the cooperation of the mapping server of the local domain, the mapping server of the ownership domain of the destination terminal and the mapping server of the domain in which the destination terminal locates, the current location information of the destination terminal is obtained by query and returned to the access router of the source end to ensure that the access router can correctly initiate a communication connection.

Description

technical field [0001] The invention belongs to the technical field of computer networks and relates to a method for realizing location management in an integrated network. Background technique [0002] The existing information network can be mainly divided into telecommunication network, TV network and Internet according to different business scopes, and the telecommunication network can be further divided into fixed telephone network and mobile telephone network. [0003] In recent years, with the rapid development of the Internet, the Internet has become the fastest growing network among the three major networks. The Internet complies with the four-layer architecture of TCP / IP including subnet layer, network layer, transport layer, and application layer, and adopts connectionless packet switching technology to transmit data and provide "best effort" services. However, this connectionless feature is also the bottleneck in the evolution of the Internet from a single data t...

Problems solved by technology

[0024] However, the mobile communication network is essentially a voice service-based network, which is different from a packet-switching network, and it does not support data services enough.

As far as its location management technology is concerned, there are also some defects. For a terminal roaming in other places, it needs to notify the HLR every time it updates its location. For mobile phone users with strong mobility, the frequency of location updates is very high. This causes the update signaling to cause a lot of extra load on the communication network

In addition, even if the users in the same VLR communicate with each other, they have to query the HLR. Due to the high proportion of calls between local users in mobile communication, this causes the HLR to be overburdened and increases the call transfer time.
