摘要

A relocation method, method for resource reservation and resource fallback in a relocation process and devices for realizing the above mentioned methods thereof are disclosed. The method for resource reservation includes: after receiving a radio resource request message sent by a source radio access network controller via a logic interface, a target radio access network controller distributes and reserves radio resources for the user terminal which needs to be relocated, and informs the source radio access network controller of a radio resource response message via the logic interface; the radio resource request message at least comprises an identification information of a target cell in which the user terminal needs to be relocated, the capability information, the identification information and the current service type information of the user terminal; the radio resource response message at least comprises the radio resource information reserved in the target cell for the user terminal by the target radio access network controller. The technical solution improves the success rate of the relocation.
