A method and device for switching between different systems

Abstract

The invention discloses an inter-system switching method and inter-system switching equipment. The inter-system cell switching success rate is improved, the cell network loads are reduced, and cell network resources are more reasonably distributed. The inter-system switching method comprises the steps that a pilot frequency measurement report reported by user equipment of a first access network cell is received, wherein the pilot frequency measurement report comprises identification information of a second access network cell, and the identification information meets preset switching conditions; according to the identification information of the second access network cell, a preset cell identification information list is searched for identification information which is the same as the identification information of the second access network cell; if the identification information which is the same as the identification information of the second access network cell is not found in the preset cell identification information list, the user equipment is triggered is to be switched into the second access network cell through a redirection process.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for inter-system switching. Background technique [0002] With the popularization of intelligent user equipment (User Equipment, UE), the packet service (Packet Service, PS) has experienced explosive growth, accounting for most of the time division-synchronized code division multiple access (Time Division-Synchronized Code Division Multiple Access, TD -SCDMA) wireless network resources, resulting in a higher and higher load on the TD-SCDMA network. Due to the handover of the user equipment from the TD-SCDMA system to the Time Division-Long Term Evolution (TD-LTE) system, the user equipment can be distributed to different networks, thereby realizing PS service offloading and reducing network load. [0003] see figure 1 , the radio network controller (Radio Network Controller, RNC) judges whether the UE supports the evolved Universal Mobile T...

Problems solved by technology

[0006] Due to the early stage of TD-LTE deployment, the network planning is not complete, and TD-LTE cells are missing configuration, which may cause the physical cell identity of the E-UTRAN cell that meets the preset conditions in the received measurement report to be listed in the static data configuration table of RNC. Therefore, the physical cell identity of the E-UTRAN cell in the measurement report cannot be found, and the switching of the PS service of the UE to TD-LTE cannot be triggered, so that the UE remains in the TD-SCDMA network; The core network (Core Network, CN) does not support the interface of the determined target cell to be handed over, or the network element interfaces of different manufacturers do not support each other, resulting in incomplete support between the core network and the UE, which makes the UE switch to the target cell to be handed over The conversion fails, so that the UE remains in the TD-SCDMA network

[0007] To sum up, in the early stage of network deployment, the success rate of inter-system handover using existing technologies is low, and when the handover fails, the UE remains in the original network, which is not conducive to reducing the load of the original network
