摘要： In a cellular telecommunications system, outage management is managed in respect of each cell B by a nominated neighbor cell A, the identity of which is recorded in a neighbor list for cell B. If a cell C, D, other than the nominated neighbor, detects a suspected outage in a cell B, the cell detecting the outage identifies the nominated neighbor A from the neighbor list of cell B, and transmits an outage report to the nominated neighbor cell A, which coordinates a handover and outage management process. This avoids multiple detections of the same outage resulting in conflicting attempts to manage the recovery process. Selection of the nominated neighbor of a cell B may be made autonomously by the cell itself or by a centralized processor, and may be done in such a way as to support network resilience by avoiding reciprocity between cells, selecting, for a cell B connected to a first backhaul system, a nominated neighbor A using a second backhaul system, and avoiding the use of cells E having intermittent or transient connections to the network.

摘要： A communication system and method for operating or evaluating the communication system includes powering a plurality of base stations each operating in at least a sleep mode and an active mode, wherein the base station operates in the sleep mode with less power consumption than in the active mode; analyzing an overall power consumption for powering the plurality of base stations with respect to a grade of service of the communication system; and switching at least one of the plurality of base stations to operate between the sleep mode and the active mode based on a result associated with the overall power consumption and/or the grade of service. Each of the plurality of base stations in sleep mode is further arranged to pass a service request to a nearby base station in the plurality of base stations such that the service request is handled by the respective nearby base station.

摘要： A method for optimizing capacity and coverage in a target area of a multi-radio access technology (RAT) cellular network. In some aspects, the performance of the higher-generation RAT and that of the lower-generation RAT are each evaluated in order to optimize the capacity and coverage of the higher-generation RAT.

摘要： The present disclosure relates to a booster radio base station, booster RBS, defining a booster cell in a multilayer cell structure and a method, performed in a booster RBS, of controlling energy consumption. The method comprises a step of receiving (S21) information from a macro RBS, defining a basic coverage providing macro cell, the information indicating a first power required to provide service to one or more wireless devices being served in an area at least in part overlapping the booster cell. The method also comprises the further steps of determining (S23) a macro bitrate power measure based on the received information, the macro bitrate power measure reflecting a service provisioning of the one or more wireless devices from the macro RBS and determining (S25) a booster bitrate power measure, the booster bitrate power measure reflecting a service provisioning of the one or more wireless devices from the booster RBS. An energy consumption state is selected (S27) from two or more energy consumption states for the booster RBS based on a comparison between the booster bitrate power measure and the macro bitrate power measure. The disclosure relates to a method, performed in a macro radio base station, macro RBS, defining a basic coverage providing macro cell, of controlling energy consumption of a booster radio base station. The disclosure also relates to a macro radio base station.

摘要： A disclosure of the present specification provides a method for establishing a packer data network (PDN) connection by a user equipment (UE). The method may comprise the steps of: transmitting a session initiation protocol (SIP)-based request message for requesting sending of a voice over LTE (VoLTE) call through a first type PDN connection; receiving, from a network node, a message including information directly or indirectly indicating that there is a problem in the first type PDN connection, instead of a normal response message to the SIP-based request message; determining to change the PDN type from the first type to a second type, on the basis of the information in the received message; and transmitting, to a mobility management entity (MME), a PDN connection request message including information on the changed second type.

摘要： In a communication method, a user equipment receives system information broadcast from a current serving cell of the user equipment and indicating frequencies different from a frequency of the current serving cell, the user equipment receives a paging signal from the current serving cell that is different from the system information and includes a request message requesting the user equipment to perform frequency redistribution in which the user equipment selects a target frequency, and performs the frequency redistribution in response to receiving the paging signal including the request message. Performing the frequency redistribution comprises the user equipment measuring quality of the frequencies included in the system information received from the current serving cell in response to receiving the paging signal including the request message, and selecting the target frequency based on a result of the measuring. The user equipment reselects a serving cell on the selected target frequency.

摘要： Antenna nodes are controlled to maintain a respective radio cell, each cell having one and the same physical cell identity. The antenna nodes are further controlled to maintain the respective radio cell in a single direction substantially along a path such that each wireless communication device, during movement in a movement direction along the path, can connect either to consecutive antenna nodes towards which the wireless communication device is moving or connect to consecutive antenna nodes away from which the wireless communication device is moving.

摘要： A communication device for aggregating long term evolution (LTE) and wireless local area network (WLAN) comprises a storage unit for storing instructions and a processing means coupled to the storage unit. The processing means is configured to execute the instructions stored in the storage unit. The instructions comprise transmitting a first message indicating support of LTE-WLAN aggregation to a base station (BS) via a LTE communication; receiving a configuration message configuring reception of at least one LTE packet transmitted via a WLAN and a WLAN configuration from the BS via the LTE communication; receiving the at least one LTE packet from the BS via the WLAN in response to the configuration message; and not showing an identification of the WLAN configured by the WLAN configuration on a display of the communication device.
