Information interaction method, system, base station and network entity

Abstract

The embodiment of the invention discloses an information interaction method, an information interaction system, a base station and a network entity. The method comprises that: the base station of a first communication system performs direct information interaction with the network entity in an access network of a second communication system by direct communication connection, wherein the first communication system is different from the second communication system. In the embodiment of the invention, the base station of the first communication system can perform direct information interaction with the network entity in the access network of the second communication system different from the first communication system by direct communication connection, so the information is prevented from being transmitted through a core network, and the information interaction delay between the base station of one communication system and the network entity of the access network of the other communication system is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to an information interaction method, system, base station, and network entity. Background technique [0002] With the continuous upgrading of communication systems, in order to save the total cost of ownership (Totoal Cost of Ownership, hereinafter referred to as: TCO), mobile operators have proposed the concept of single radio access network (Single Radio Access Network, hereinafter referred to as: SRAN), that is, different Types of communication systems, such as Global System for Mobile Communications (hereinafter referred to as GSM), Universal Mobile Telecommunications System (hereinafter referred to as: UMTS) and Long Term Evolution (hereinafter referred to as LTE) Build a network together. [0003] In the system architecture formulated by the 3GPP organization, the GSM access network GERAN includes a base station controller (Base Station...

AI Technical Summary

Problems solved by technology

[0006] In the prior art, when a base station of one communication system interacts with a network entity in an access network of another communication system, information needs to be transmitted through a core network, which causes a base station of one communication system to interact with a network entity of another communication system. The delay in information interaction between network entities in the access network of the communication system is large
