  • Patent number: 10575234
    Abstract: A first base station receives from at least one second base station, a first message comprising capability information indicating a number of bearers supported by the at least one second base station. The first base station receives from a wireless device, a measurement report comprising a received power of a cell of the second base station. The first base station determines a handover to the cell based on the measurement report and the number of bearers supported by the at least one second base station. The first base station sends a handover request to the at least one second base station in response to the determining of the handover.

  • Patent number: 10554362
    Abstract: A base station encodes antenna configuration information of a neighboring cell of a first cell, and sends encoded information relating to the antenna configuration information of the neighboring cell to a user equipment (UE). The UE is capable of communicating with the base station in the first cell. The UE receives the encoded information; decodes the antenna configuration information of the neighboring cell from the encoded information; and performs determination of predetermined time-frequency resource according to the antenna configuration information of the neighboring cell. The predetermined time-frequency resource is used by a base station of the neighboring cell for transmitting pilot measurement information.

  • Patent number: 10462715
    Abstract: A method for assisting in a cell re-selection procedure in a cellular communication system comprises obtaining (S1) of information comprising radio conditions and/or user equipment population related to at least a serving cell and optionally also related to at least one neighbor cell to the serving cell. The obtained information is compared (S2) with a criterion for enforced cell re-selection procedure. If the criterion for enforced cell re-selection procedure is fulfilled by the obtained information, an enforcement of, or an action for increasing the probability for causing, a cell re-selection procedure of at least one user equipment within the serving cell is initialized (S3). Devices for performing such a method are also disclosed.

  • Patent number: 10412646
    Abstract: A method and system for transferring user equipment (UE) in a mobile communication system are disclosed. According to the method, a source core (CN) network determines to transfer a UE that it serves and sends a transfer instruction carrying UE transfer restriction information to the UE; an access network receives a transfer request that is sent by the UE according to the restriction information carried in the transfer instruction; the access network selects a target CN entity that is different from the source CN entity for the UE; and the UE is transferred to the target CN entity. The method and system provided by the disclosure are applicable to user transferring between CN entities in any communication network. The transferring is initiated by a network side entity, and a more preferable CN entity is selected for the UE to provide a better service.
