LTE multi-frequency system based on multi-module equipment and method for realizing system frequency switching

Abstract

The invention discloses a LTE multi-frequency system based on multi-module equipment and a system frequency point switching realization method; the method comprises the following steps: adding a CPE multi-frequency module group function in the system, thus sharing information between the multi-frequency system core net and each frequency point CPE module; adding expansion information in related signaling like adhering, paging and S1 release in the standard LTE, thus allowing the core net to activate and release each CPE module in the CPE module group in a frequency point switching process; adding a communication control mechanism between the CPE modules, thus sharing the Ethernet information. The method can effectively solve the system frequency point switching problems when full-band interference covering the LTE system all communication frequency bands exists, thus allowing the user terminal to have no perception on network changes, and preventing related problems caused by manual operation errors; the system has excellent expandability, thus greatly reducing the system upgrading cost.

Description

technical field [0001] The invention relates to a method for realizing system frequency point switching in an LTE multi-frequency system, and belongs to the technical field of wireless network communication. Background technique [0002] With the development of communication technology and the flattening of network architecture and the continuous emergence of various high-speed broadband mobile wireless access technologies, in order to ensure the competitiveness of 3GPP (3rd Generation Partnership Project, the third generation mobile communication partnership project) and consider the evolution of wireless communication systems It can provide higher transmission rate with lower cost and shorter transmission delay, and at the same time support mobility between 3GPP internal access systems and mobility between 3GPP access systems and non-3GPP access systems, Improve 3GPP system capability and performance and reduce costs. The mobile communication network proposes the next-gen...

Problems solved by technology

First of all, the new CPE module needs to independently detect the startup of the new base station and connect to the new base station module. The user terminal also needs to independently detect the replacement of the CPE module in order to reconnect to the new CPE module and resume service transmission. The impact of the two types of detection and access time The overall delay of frequency switching; secondly, because the CPE module provides DHCP services for user terminals, when using a new CPE module, a new IP address will be re-assigned to the user terminal, and the change of the IP address will cause the service of the user terminal to be re-initialized. In order for the new CPE module to correctly route data packets to the corresponding user terminals, this will cause long-term interruption of user services and seriously affect user experience
