Information acquisition method, gateway proxy and network system

Abstract

The embodiment of the invention discloses an information acquisition method, which comprises that: a gateway agent receives query information sent by a source information server and the query information carries the identification information indicating a purpose information server. The source information server and the purpose information server pertain to different information service fields; the gateway agent sends the query information to the purpose information server indicated by the query information; the gateway agent receives query response information returned by the purpose information server and then sends the query response information to the source information server. Correspondingly, the embodiment of the invention also provides a gateway agent and a network system. The technical proposal provided by the invention can save the processing capacity resources and the bandwidth resources of network nodes while acquiring the information.

Description

Information acquisition method, gateway agent and network system technical field The invention relates to the technical field of communication, in particular to an information acquisition method, a gateway agent and a network system. Background technique Currently, the Media Independent Handover (MIH) solution proposed by IEEE (Institute of Electrical and Electronics Engineers) 802.21 working group introduces a framework that can ensure the continuity of service switching between different types of media. In order to realize the seamlessness and continuity of this handover, a set of handover function sets needs to be implemented between network elements, and these handover function sets are configured in the mobility management protocol stack of network elements to form a new protocol layer. It is called the MIH protocol layer, referred to as the MIH layer. The MIH layer protocol stack provides the following services: MIH Event Service (MIH-ES), which is used to provide e...

Problems solved by technology

There are certain defects in this prior art. When the mobile node wants to obtain the information of the PoA across the IS domain, it needs to perform the cross-domain information acquisition process through the multi-hop of the network access point PoA, and the PoA is a key service node of the wireless network. Its processing power resources and bandwidth resources are very precious, and the information acquisition process of the prior art will seriously waste the processing power resources of PoA, increase the average load of PoA, and waste the bandwidth resources of PoA at the same time
