Long term evolution (LTE)network access method, access network and convergence gateway

Abstract

The invention discloses a long term evolution (LTE) network access method, access network and convergence gateway. An LTE network provided in the invention comprises the convergence gateway and a plurality of micro base stations, wherein the convergence gateway is connected with the plurality of micro base stations. The method comprises the following steps: any one or multiple micro base stations in the plurality of micro base stations sends or send control plane data to the convergence gateway; the convergence gateway receives the control plane data, converges the control plane data and sends the converged control plane data to a mobility management entity of a core network; and the convergence gateway receives the control plane data that the mobility management entity sends to one or multiple micro base stations of the plurality of micro base stations, and distributes the control plane data to the corresponding micro base stations. Through the technical scheme provided in the invention, the number of logic interfaces and signaling interaction between the access network and the core network are reduced, and the core network resources are saved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a long-term evolution network access method, access network and convergence gateway. Background technique [0002] In order to effectively cope with the rapid growth of data traffic in the future under the condition of limited spectrum resources, small cell enhancement technology has become an effective solution in Long Term Evolution-Advanced (LTE-A) version 12 and subsequent evolution. Program. [0003] For the micro cell, due to the low transmit power of the micro base station and the high potential application carrier frequency, its coverage area is much smaller than that of the macro cell. Therefore, for typical application scenarios such as hot urban areas and large shopping areas, more micro cells need to be deployed to ensure effective coverage and speed enhancement in the above areas. [0004] like figure 1 As shown, the existing LTE-A wireless access net...

AI Technical Summary

Problems solved by technology

When there are many micro base stations in the network, if the existing architecture is adopted, each micro base station needs to be directly connected to the core network, resulting in a large increase in the number of logical interfaces and signaling interactions between the micro base station and the core network element S1, and causing mobile The burden of management operations on the management entity (MobilityManagement Entity, MME) has increased dramatically

In particular, when more micro cells need to be deployed, a larger number of micro base stations will be used, resulting in a greater number of logical interfaces and signaling interactions with the core network, which not only occupies more core network resources but also makes it difficult to centralize manage
