Abstract

The present invention provides a redirection method for a terminal, being characterized in that: the carrier being fixedly resident in the CDMA network for a dual mode terminal is prearranged,the LTE base station sends the redirection information to the dual mode terminal,the redirection information comprises a redirection target carrier configured by the LTE base station,the dual mode terminal and teh CDMA access network perform session negotiation and are informed of the resident carrier appointed by the CDMA access network,both the redirection target carrier and the resident carrier fix the resident carrier in the CDMA network for the pre arranged dual mode terminal,and when the dual mode terminal is rediected to the CDMA network from the LTE network and searches the redirection target carrier in the CDMA network, and initiates the access process on the redirection target carrier in the CDMA network. Compared with the prior arts, the technical scheme provided by the present invention reduces the business break period for redirecting the dual mode terminal from the LTE network to the CDMA network and improves the user experience.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a terminal redirection method and device. Background technique [0002] At present, existing CDMA (Code Division Multiple Access, Code Division Multiple Access) operators tend to select LTE (Long Term Evolution, Long Term Evolution) technology as a next-generation network to meet the growing demand for wireless data services. Since it is impossible to deploy LTE in place at one time, operators generally deploy LTE in hotspots at the initial stage, and then gradually expand the deployment area. This deployment method is as figure 1 As shown, the operator's existing CDMA EVDO (Code Division Multiple Access Evolution Data Only, Code Division Multiple Access Evolution Data Only) network has a large coverage area and is wide coverage. The LTE network deployed in the hotspot area is superimposed on the EVDO relative to the LTE network deployed in the hotspot area, fo...
