  • Patent number: 11696201
    Abstract: Embodiments of the present disclosure relate to a method, a device and a computer-readable medium for guaranteeing communication service. According to embodiments of the present disclosure, a source network device that currently serves the terminal device transmits, to a target network device which will serve the terminal device, information about the amount of resources of network slices utilized by the terminal device. The target network device configures the amount of resources based on the information. In this way, successful handover of the terminal device from the source network device to the target network device is guaranteed, so as to ensure continuity of communication services of the terminal device. In addition, embodiments of the present disclosure creates a network slice in the target network device, which avoids possible interruptions of communication service caused by mapping from the terminal device to the slices supported by the target network device.

  • Patent number: 11601853
    Abstract: The invention provides a method of and apparatus for controlling a ProSe service in a communication system. An eNB sends a first PLMN identifier, and carrier frequency information of another PLMN to indicate at least one carrier frequency at which a UE of the other PLMN can carry out the ProSe service, to a UE in a shared cell, and if the UE is in an idle state, then the UE reselects a cell or selects a PLMN; or if the UE is in a connected state, then the UE performs a handover procedure. If the handover procedure fails, then the UE releases an RRC connection to enter the idle states, or is DRX-configured and carries out the ProSe service in a DRX sleep time. With the solution of the invention, the UE can reselect or be handed over to the cell to carry out the ProSe service at the carrier frequency indicated by the carrier frequency information to thereby avoid the problem of an overload arising from too many ProSe services being carried out concurrently in the shared cell.

  • Patent number: 11469873
    Abstract: The objective of the present disclosure is to provide a method, apparatus and system of ACK/NACK reporting for Cat-M mechanism. Here, a user equipment feeds back an ACK/NACK message to an eNB on PUSCH based on received downlink data, wherein when computing the number of resource elements occupied by the ACK/NACK message on PUSCH, the number of OFDM symbols in a guard period is ruled out. This may effectively lower the UE's PUSCH data code rate, and meanwhile enhance the eNB's decoding performance on PUSCH.
