Converged communication attribution transfer and registration method suitable for narrowband network

Abstract

The invention provides a converged communication attribution transfer and registration method suitable for a narrowband network. The converged communication attribution transfer and registration method comprises the following steps: step 1, designing a local registry TR, a local roaming immigration table TMI and a local roaming emigration table TMO; step 2, establishing an attribution adaptive evolution method, and performing attribution migration; step 3, carrying out prefix splitting and merging to realize nearby local registration access; and step 4, completing registration by roaming users. Attribution dynamic adjustment is made so that the large number of roaming registered users are adjusted into local registered users; therefore, the bandwidth requirement and the link quality requirement on the communication network are greatly reduced; the method can support the quick deployment of the converged communication system in communication environments with narrow-band and weak-connection link characteristics, such as industrial Internet of Things, battlefield communication, narrow-band ad hoc networks and cluster communication networks, supports the random access and roaming switching of terminals, and can improve the robustness of the converged communication system.

Description

technical field [0001] The invention belongs to the field of communication network technology and communication service technology, and in particular relates to a fusion communication ownership transfer and registration method suitable for narrowband networks. Background technique [0002] Converged communication refers to a new communication mode that integrates computer technology and traditional communication technology. It integrates computer network and traditional communication network on one network platform to realize telephone, fax, data transmission, audio and video conferencing, call center, instant communication, etc. application services. A converged communication system usually consists of an access layer, a control layer, and a service layer. The access layer realizes the interconnection of heterogeneous networks and the comprehensive access of multiple types of terminals, and shields the differences in the communication systems and signaling of various types...

AI Technical Summary

Problems solved by technology

When there are a large number of roaming users in the system, the additional network overhead will increase significantly. For the battlefield communication environment with limited bandwidth resources, it will seriously affect the normal operation of the integrated communication system itself and other business systems.
