Abstract: Provided are a method, system, device for controlling congestion or overload and an eNB. The method includes: one or more eNBs configured to detect congestion or overload of user plane data are selected, and the one or more eNBs selected are notified; the one or more eNBs selected detect a congestion or overload event of the user plane data; when a triggering condition is met, the one or more eNBs selected send congestion or overload indication information to a GCS AS; and the GCS AS determines a start or end of congestion or overload which occurs in an MBMS area according to the congestion or overload indication information, and correspondingly selects a manner in which trunking service data are sent. By the technical solutions of the disclosure, the problem of influence for a trunking service when congestion or overload occurs in a network may be solved.

Abstract: Disclosed are an MBMS bearer-based method and system for reporting a congestion state in cluster communication and a storage medium. The method comprises: when user-side and/or control-side congestion or overload indication information reported by a network node of a multimedia broadcast multicast service (MBMS) bearer-based cluster service is received, a cluster service application server determines a target user equipment (UE) and a cluster service being affected, executes a corresponding policy, and mitigates impacts of congestion or overload on the target UE receiving the cluster service; and, when resume indication information reported by the network node is received, the cluster service application server utilizes the restored network node to select a bearer mode for transmitting the cluster service. The technical solution of embodiments of the present invention mitigates the impacts of network congestion or overload on the cluster service, thus enhancing user experience with the service.

Abstract: Provided are a method, device and UE for sending indication information, and a method and device for receiving an MBMS. The method for sending indication information includes: UE determining that the UE has left one or more MBSFN areas which can carry a predetermined MBMS; the UE sending indication information to a network side. The method for receiving MBMS includes: UE receiving a specified MBMS which is carried in one or more MBSFN area to which a source cell where the UE is currently located belongs; after the UE performs cell reselection and resides in a target cell, in the case that one or more MBSFN areas to which the target cell belongs are different from one or more MBSFN areas to which the source cell belongs, the UE acquiring a condition of one or more MBMSs which are carried in the one or more MBSFN areas to which the target cell belongs; and the UE continuing receiving the specified MBMS in the target cell according to the acquired MBMS condition.

Abstract: Embodiments of the prevent invention provide a network access authentication method and device. The method comprises: receiving an authentication request message sent by a first serving network, wherein the authentication request message carries a user equipment pseudonym identifier generated by a user equipment; determining whether a local user equipment pseudonym identifier is asynchronous with the user equipment pseudonym identifier generated by the user equipment; and obtaining, if the determination result is yes, an encrypted international mobile subscriber identity (IMSI) to carry out network access authentication on the user equipment. The embodiments of the present invention can solve the problem that a network access process in the related art does not provide a processing method for the case where the user equipment pseudonym identifier in the user equipment is asynchronous with the user equipment pseudonym identifier in a home network.

Abstract: Disclosed are an MBMS bearer-based method and system for querying a node state in cluster communication and a storage medium. The method comprises: a cluster service application server transmits to a network node employing a multimedia broadcast multicast service (MBMS) bearer for transmitting a cluster service a request message for reporting a node state, receives node state information reported by the network node, selects, on the basis of the node state information, a mode for transmitting the cluster service, and mitigates impacts of congestion or overload on a target UE receiving the cluster service; the node state information comprises a congestion/overload identifier, an MBMS service area identifier, an MBMS service identifier, a congestion/overload start/end identifier. The technical solution of embodiments of the present invention mitigates the impacts of congestion or overload on the cluster service, thus enhancing user experience with the service.
