    摘要： The disclosure discloses a method for reporting measurement capability, including: a UE reports the measurement capability of the UE to a base station, wherein the measurement capability is the capability of whether a measurement gap is required for the UE to execute different-frequency and different-system measurement when the UE operates in one frequency band or in a carrier aggregation scenario; and after acquiring the measurement capability of the UE, the base station determines whether to configure a measurement gap for the UE according to the frequency band to which carriers configured to be aggregated for the UE belong, the frequency band to which the carrier frequency for a measurement object of a currently configured measurement task belongs, and the measurement capability of the UE. The disclosure also discloses a UE correspondingly. By the disclosure, the base station is capable of not configuring a measurement gap for the UE if unnecessary, so that the influence of the different-frequency and different-system measurement to the service can be reduced, and possible resource waste caused can be avoided when the UE carries out measurement in the carrier aggregation scenario.

    摘要： The embodiment of the present invention discloses a connection management method and an access network element, wherein the method is applied to a scenario in which a user equipment (UE) establishes connections with at least two access network elements at the same time, including: when determining that at least part of the connections between the UE and one resource connection node need to be deleted or moved, a primary connection node instructing the resource connection node to correspondingly delete or move the at least part of the connections, and the resource connection node or the primary connection node instructing the UE to correspondingly delete or move the at least part of the connections. The embodiment of the present invention achieves a connection management between the UE and the resource connection node in a dual-connection architecture, and particularly achieves the connection management when the resource connection node is no longer suitable for providing the UE with information transmission or no longer suitable for providing the UE with information transmission of all the previously established connections.

    摘要： A security key generating method, device and system are provided, wherein, the method is used for generating a security key in the process of the handover to an EUTRAN network from other network, the method includes: an MME generates a security key based on a root key K ASME of the EUTRAN network, a specific value and/or other parameters and transmits a handover request message carrying the security key to a target evolved Node B, i.e. eNB; a UE generates the security key which used by the target eNB based on the root key K ASME of the EUTRAN network, the specific value and/or other parameters. The application of the present invention adopts a specific value, K ASME and/or other parameters to output a security key, which can solve the problem existed in the related technology, the problem is that the middle security key used by access layer while handover between different access system can not be generated, and then it can not realize the security protection of the access layer. So the application of the present invention makes the signaling and/or data of the access layer be efficiently protected, thereby improving the security of the access layer.

    摘要： A method for notifying a terminal of an update on system information in a long term evolution system, which is used for notifying the terminal after the system information changes by a network side, after the system information changes, the network side notifies the terminal that the system information has changed within the system information modification period, wherein the length of the system information modification period is an integer multiple of discontinuous reception (DRX) period, and the DRX period is a period that the terminal receives paging message in the idle status. By using the method of the present invention, because the system information modification period is specified as an integer multiple of the DRX period, it makes sure that each terminal in the RRC_IDLE state receives the paging message including update information of the system information at least once.
