Method and device for inter-cell handover of different systems

Abstract

The invention discloses a method and device for inter-cell handover of different systems, belonging to the technical field of communication. The present invention receives the measurement report sent by the terminal through the RAN server of the wireless access network, determines the target different-mode cell of the terminal according to the measurement report, and configures resources for the terminal in the target different-mode cell, and the configured resources are the The resource used when the terminal accesses the target different-standard cell, the RAN server sends a handover command to the terminal, the handover command is used to instruct the terminal to switch to the target different-standard cell, and the handover command carries the target different-standard cell The identifier and the configured resource information, wherein the RAN server is used to manage the serving cell of the terminal and the target cell of a different system, so that when switching between cells of a different system, the handover can be realized without crossing the core network, reducing the Signaling interaction between the source core network and the target core network.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for inter-cell handover of different systems. Background technique [0002] With the rapid development of communication technology, various heterogeneous networks have emerged, for example, Global System For Mobile Communication (GSM), Wideband Code Division Multiple Access (WCDMA) and long-term acting (Long Term Evolution, LTE) and so on. The multiple different-standard networks correspond to multiple different-standard cells. With the extensive coverage of the multiple different-standard cells, the terminals accessing the cells are likely to move from one standard cell to another standard cell during the movement process. For example, when moving from a cell of a WCDMA network to a cell of an LTE network, in order to ensure that the terminal can continue to maintain the access state during the moving process, the terminal needs to be handed o...

Problems solved by technology

[0004] During the above implementation process, the inventors found at least the following problems in the prior art: if the terminal is handed over between two cells of different standards, the handover process needs to cross the core network, and there are a lot of information between the source core network and the target core network. Order interaction, resulting in a large switching delay
