SECURITY KEY CONTEXT DISTRIBUTION METHOD, MOBILE MANAGEMENT ENTITY, AND BASE STATION

摘要

Disclosed are a security key context distribution method, a mobile management entity, and a base station. The security key context distribution method comprises: a first indication is received by a mobile management entity from a main base station, where the first indication is used for requesting the mobile management entity for a path switching and for indicating that the path switching is to be triggered by a carrier aggregation among base stations; the path switching is processed on the basis of the first indication; a security key context for use in the path switching is kept unchanged on the basis of the first indication, and a second indication is transmitted to the main base station to indicate to the main base station to keep the security key context unchanged; or, a third indication is transmitted to the main base station to indicate to the main base station to acquire the number of flips of a counter of a next hop link in the security key context. It should be noted that the technical solution provided in the present invention allows for effectively increased reliability in path switching when carriers are aggregated among base stations.
