Method and device of cross-domain service strategy interaction for fixed mobile convergence network

Abstract

In order to solve the problems that in the existing technology of fixed-mobile convergence, a fixed access network and a mobile core network are respectively provided with a cross-domain policy so as to cause low real-time and poor flexibility. The invention provides a method and a device of cross-domain service strategy interaction for the fixed mobile convergence network, wherein the fixed access network and the mobile core network interact with cross-domain strategy control information, and carry out corresponding strategy control processing. Optimally, the fixed access network and the mobile core network respectively carry out cross-domain strategy control information interaction respectively through strategy controllers thereof, and can carry out strategy control processing in real time so as to improve flexibility of a fixed-mobile convergence network. In the embodiment, the mobile core network can send out a cross-domain policy configuration service requests such as a broadcast and / or multicast service policy configuration request, and the like to the fixed access network in real time, the fixed access network can configure corresponding service strategy for the fixed access network, improve the properties of the fixed access network for providing broadcast and / or multicast services.

Description

technical field [0001] The invention relates to a communication network, in particular to a fixed-mobile convergence network. Background technique [0002] In the current 3G wireless communication technology, the communication based on the macro cell will lead to the decline of indoor service quality due to the poor penetration characteristics of the wireless frequency used in the building. Therefore, research on fixed-mobile converged networks based on Femtocell and other similar technologies has become a hot spot in the industry. Such as figure 1 In the logical structure of the fixed-mobile converged network shown, femtocell base stations such as base station routers (BSR for short) are deployed indoors and connected to the fixed access network via access nodes (AN for short). ; The fixed access network is connected to the Brick and other mobile core gateways of the mobile core network through the Broadband Network Gateway (BNG) via the IP network, and the Brick of the m...

AI Technical Summary

Problems solved by technology

In this case, if the AN to which a BSR to which the mobile device belongs has not opened the corresponding port, and the fixed access network has not configured VLAN, then the fixed access network cannot provide the mobile device with bearer broadcast and / or Communication resources for multicast services

In all scenarios that require interaction between the fixed access network and the mobile network (such as the fixed network's legal interception and monitoring of the communications of mobile devices passing through its network, etc.), there are similar problems that cannot be solved in the prior art
