Embodiment Construction

[0049] In order to enable the NGN network to support mobility management, the present invention adds a functional entity for mobility management to the control part and the bearing part of the transport layer of the existing NGN network system, and cooperates with the existing functional entity through the added functional entity. Carry out mobility management on users, especially realize the same mobility management as MIP6 technology.

[0050] Referring to Fig. 3, the control function entity of the NGN network transport layer has also increased the mobility control entity in addition to the existing user database, authentication and authorization entity (TAA), network access configuration control entity and location management entity; The bearer control functional entity adds the mobile forwarding entity. In this way, the separation of control and bearer of mobility management is realized, and it is fully integrated with the NGN network.

[0051] The transport mobility cont...

Abstract

The invention discloses a mobile management method in the NGN network system, the method being: the mobile terminals send the register message to the NGN network, and in the NGN network, the functional entities register the users and return to the registration response; after the said mobile terminals receive the registration successful response, they send the mobile registration information to the NGN network, and in the NGN network, the functional entities for mobile management in the user's hometown register the user and return the registration response; and in the NGN network, after the functional entities for mobile management for mobile management successfully register the mobile terminals, according to user requests, provide the corresponding communication services. The invention also discloses a NGN network system.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a next generation network (NGN) system and a method for realizing mobility management thereof. Background technique [0002] With the popularization and application of 2.5G / 3G wireless network and broadband IP network, the industry has proposed the concept of Next Generation Network (Next Generation Network), requiring NGN to be compatible with all current networks, able to transmit all business media, and provide new The service improvement provides good interface and expansion ability, and guarantees ubiquitous communication, security and good quality of service (QoS) ability. [0003] The basic architecture model of NGN is shown in Figure 1. The entire network model is divided into a service plane and a transmission plane. The transmission plane is divided into four functional parts, network access control function, resource access control function, network access funct...
