Embodiment 7

[0276] Such as Figure 7 As shown, the core network signaling service node in the seventh embodiment of the present invention includes:

[0277] The processor 701 is configured to read a program in the memory 704 and execute the following process:

[0278] A path switch message from a target wireless network node is received through the transceiver 702, where the path switch message is sent by the target wireless network node after the terminal in the source wireless network node completes the switch, and the core network signaling service The node is the core network signaling service node that the source wireless network node and the target wireless network node are connected together; according to the terminal identifier in the path switch message, the terminal context is determined, and the terminal context is determined according to the terminal context. The service plane bearer of the terminal is switched from the source wireless network node to the target wireless network no...

Abstract

The invention relates to a network switching method and device, belongs to the technical field of radio communication, and aims at solving the problems that time for switching between UMTS and LTE is relatively long and signaling node of the network is increased in the prior art. A source radio network node sends a switching request message to a target radio network node directly after it is determined that enhanced switching can be carried out; and after receiving the switching request message, the target radio network node sends a switching command to a terminal. Due to the fact that the source radio network node can send the switching request message to the target radio network node directly, signaling interaction between core networks is reduced, time needed for a switching process is reduced, and the signaling load in the network is reduced.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, and in particular to a method and equipment for switching between networks. Background technique [0002] The long-term coexistence of UMTS (Universal Mobile Telecommunication System) / HSPA (High-Speed ​​Packet Access) and LTE (Long Term Evolution) networks makes interoperability between UMTS and LTE Sex is in a very important position. [0003] In the 3GPP (3rd Generation Partnership Project, Third Generation Mobile Communication Standardization Organization) TS23.401 protocol, the UE switches between UMTS and LTE in a process similar to the S1 handover in LTE. The specific process is as follows: [0004] (1) Handover preparation phase: The source eNB (evolved base station) first sends a handover request to the source MME (Mobility Management Entity), and the MME uses the TargetRNC Identifier in the message; RNC, Radio Network Controller, wireless The network controller) determi...
