摘要： This disclosure claims a method for security processing during RRC connection re-establishment, comprising: a UE sends an RRC connection re-establishment request message to the eNB; after receiving the request message, the eNB determines whether an original access layer security algorithm used by the UE is supported by the eNB itself according to the current status and configuration; if supported, the communication protection with UE is implemented via the original access layer security algorithm; if not supported, according to the security capability of UE, the access layer security algorithm which has the highest priority and is supported by the UE is selected from the access layer security algorithms configured by the eNB itself to be the new access layer security algorithm, and the communication protection between the eNB and the UE is implemented by the new access layer security algorithm. This disclosure also claims a system for security processing during the RRC connection re-establishment.

摘要： A method, a system and an evolved NodeB (eNB) apparatus for implementing inter-eNB switch are disclosed in the present invention. The method includes: when a user equipment switches from a source-side eNB to a target-side eNB, if the target-side eNB acquires via the Mobility Management Entity (MME) that the Serving Gateway (S-GW) has changed, the target-side eNB adds the new route relation of the S-GW and then updates the General Packet Radio Service (GPRS) Tunnelling Protocol User Plane (GTP-U) entity. The present invention can effectively solve the problem of the uplink data packet loss due to the time difference existing between the update to the Tunnel Endpoint Identifier (TEID) and the routing table by the eNB when inter-eNB switch is performed via X2 and the S-GW has changed, thus enhancing the user experience during the switch.

摘要： A method for a base station to obtain radio capability information of a User Equipment (UE) in long term evolution system comprises that: a mobility management entity sends an initial context setup request message to the base station, and the base station determines whether the received initial context setup request message contains an Information Element (IE) of forbidden inter radio access technologies; when contains, the base station writes the radio access technology types which are not included in the IE of forbidden inter radio access technologies into a query message, and sends the query message to the UE; otherwise, the base station writes all radio access technologies supported by protocol into a query message and sends the query message to the UE; after receiving the query message, the UE sends the UE radio capability information of radio access technologies supported by the UE itself to the base station. The above method avoids the blindness of writing query message for the base station, which reduces the overhead of the air interface, thereby shortens the connection delay of the UE in the long term evolution system.
