Callee emergency call processing method and system

The invention provides a callee emergency call processing method and system, and the method comprises the steps: caller UE transmits an emergency call building request; an MME receives the emergency call building request, and transmits an emergency S1AP paging message after callee UE is detected to be unoccupied, wherein the emergency S1AP paging message is an S1AP paging message containing first emergency identification and the first emergency identification is used for identifying that the current paging is emergent paging; a base station receives the emergency S1AP paging message, and then transmits an emergent paging message according to RRC (radio resource control), wherein the emergent paging message is a paging message containing second emergency identification, and the second emergency identification is used for identifying that the current paging is emergent paging; the callee UE receives the emergent paging message, and then transmits an RRC connection building request containing third emergency identification, wherein the third emergency identification is used for identifying that current RRC connection is emergent RRC connection. The method and system can enable the callee UE to achieve the emergent RRC connection.
