Abstract
A paging method includes, when needing to page a user equipment (UE) according to service requirements, a mobile switching center (MSC) analyzing a user identification if finding that subscriber data are lost at present, judging whether the UE has a possibility of residing in a long term evolution (LTE) network, if yes, finding out one or more mobility management entities (MMEs) which are overlapped with the coverage area of the MSC itself, and sending a paging message for the UE to the MMEs. An MSC includes a first module, a second module, a third module and a fourth module. With the paging method and apparatus provided, the UE in the LTE can be successfully paged under the condition that a visitor location register (VLR) loses the subscriber data and a home location register (HLR) fails to return an MME identification.
