SECURITY KEY CONTEXT DISTRIBUTION METHOD, MOBILE MANAGEMENT ENTITY, AND BASE STATION |
摘要 |
Embodiments of the present invention disclose a method of distributing a security key context, a mobility management entity, and a base station, where the method of distributing a security key context includes: receiving, by a mobility management entity, a first indication from a primary base station, where the first indication is used for requesting a path switch from the mobility management entity and indicating that the path switch is triggered by carrier aggregation between base stations; processing the path switch according to the first indication; and according to the first indication, keeping a security key context for the path switch unchanged, and sending a second indication to the primary base station, to indicate the primary base station to keep the security key context unchanged; or sending a third indication to the primary base station, to indicate the primary base station to acquire a quantity of times of reversal of a next hop chaining counter in the security key context. It should be noted that, technical solutions provided in the present invention can effectively improve reliability of a path switch during carrier aggregation between base stations. |
