    Abstract: A terminal receives configuration information from a first access network device. The configuration information includes a paging area information that indicates a paging area for the terminal in a first mode. In the first mode, the terminal sends a first message to a second access network device when the terminal is in a cell that does not belong to the paging area. The first message includes a paging area update indication. The terminal then receives a connection establishment indication from the second access network device, and establishes a connection between the terminal and the second access network device. The terminal sends a second message to a core network device using the established connection between the terminal and the second access network device, the core network device releases a connection between the first access network device and the core network device established for the terminal in response to the second message.

    Abstract: Embodiments of the present invention provide a paging method, apparatus, and system, so as to implement paging of UE in an area with relatively poor signal coverage. UE includes: a receiving unit, configured to receive a broadcast message sent by a base station; and a determining unit, configured to determine whether the UE is first UE where the determining unit is further configured to: in a case in which it is determined that the UE is the first UE, determine a start PF and a start PO according to the first radio frame parameter; the determining unit is further configured to determine a first subframe set according to the start PF and the start PO; and the receiving unit is further configured to receive, according to the start PF, the start PO, and the first subframe set, a paging message sent by the base station.

    Abstract: Embodiments of the present disclosure disclose a discontinuous reception (DRX) implementation method, a DRX configuration method, and a related device. The DRX implementation method includes: receiving, by a terminal, DRX configuration information sent by a base station, where the terminal supports short transmission time interval (TTI) subframe transmission; and performing DRX according to the DRX configuration information, a system frame number (SFN), and a number of a short TTI subframe, where the short TTI subframe is a subframe numbered according to a short TTI, and a length of the short TTI subframe is less than 1 ms. In the embodiments of the present disclosure, DRX can be implemented at a short TTI, so as to improve overall performance of a system.

    Abstract: The present invention discloses a method and an apparatus for reporting an unlicensed spectrum capability The method includes the following: UE reports a list of unlicensed spectrums that can be supported by the UE and a maximum bandwidth value of each unlicensed spectrum to a serving base station of the UE, so that the serving base station of the UE can configure an unlicensed spectrum resource for the UE according to a received unlicensed spectrum capability parameter. Therefore, a base station can configure an unlicensed spectrum resource according to unlicensed spectrum capabilities that can be supported by different UEs.

    Abstract: The present invention discloses a method and device for maintaining service continuity. The method for maintaining service continuity includes: receiving, by a base station, a first notification, which is sent by an MCE, for stopping scheduling of an MBMS service; and notifying, by the base station, user equipment of MBMS service scheduling stop information, and continuing to schedule the MBMS service. In this way, a service interruption time that is caused when UE receives a service after an MCE stops scheduling of the service can be effectively reduced.

    Abstract: Embodiments of the present disclosure disclose a mobility management method, user equipment, and a base station. The mobility management method may include: receiving, by user equipment UE in a connected mode, a source identifier of the UE from a first base station, where the source identifier is used to uniquely identify the UE in the first base station; entering, by the UE, a low-overhead state in the case that a low-overhead activation condition is satisfied, where in the low-overhead state, the UE stores a connection context of the UE in the connected mode, and camps on a cell according to a cell reselection criterion during movement; and reporting, by the UE when a first preset condition is satisfied, the source identifier to a second base station to which a second cell belongs, where the second cell is a serving cell on which the UE currently camps.
