Abstract: The invention provides a method and an apparatus for controlling secondary carriers in an asymmetric uplink carrier aggregation, the method includes: an eNB transmits configuration information of uplink secondary carriers configured for a UE to the UE, wherein the configuration information includes carrier-specific common configuration information and/or UE-specific configuration information; furthermore, the eNB schedules the uplink secondary carriers via a physical downlink control channel PDCCH of the downlink primary carrier, so that the UE performs a scheduling of a PUSCH to the eNB via the uplink secondary carriers, thus realizing a control of the secondary carriers in the asymmetric uplink carrier aggregation and greatly improving the uplink throughput.

Abstract: Embodiments of the present disclosure provide a unified authentication method for application in a trunking system, a server and a terminal. The method includes: an application service network element of a server receives a registration request transmitted by a terminal and transmits the registration request to an authorization authentication network element, where the registration request carries a token indicating a unique identity of a user initiating the registration request, and the token is assigned by the authorization authentication network element of the server to the user when the user logs onto the terminal; the authorization authentication network element then performs a token authorization to the user according to the token; and finally the application service network element performs an application service interaction with the terminal if the token authorization is passed.

Abstract: The present invention provides a resource configuration method, a resource deletion method and a device. The resource configuration method includes: receiving a group establishment request carrying a group identifier of a group to be established; acquiring, according to the group identifier of the group to be established, a base station list and a tracking area list of the group to be established; the base station list includes a base station in which a registered subscription user equipment of the group to be established locates at present, the tracking area list includes a tracking area in which the registered subscription user equipment of the group to be established locates at present; if the base station list is not empty, configuring, according to the base station list and the tracking area list, a resource for the group to be established.
