    Abstract: The present disclosure relates to discontinuous reception communication synchronization methods and apparatus. One example method includes receiving a system message that is broadcast by a base station and that indicates that the base station supports a capability of extended discontinuous reception (DRX), sending an extended DRX value to a network element of a core network, receiving, from the network element of the core network, extended DRX support information indicating that the network element of the core network supports the extended DRX, calculating a paging time using the extended DRX value, and receiving a paging message delivered from the base station according to the paging time.

    Abstract: Embodiments of the present invention relate to the communications field and provide a bearer setup method, apparatus, and system. The method includes: receiving, by an MME, indication information, where the indication information is used to indicate a bearer type that is set up for UE; and setting up, by the MME, a bearer for the UE according to the indication information. By means of the method, indication information used to indicate a bearer type that is set up for UE is received, and different types of bearers are set up for the UE according to the indication information, so that an MME can adjust the bearer type in real time as required and set up different types of bearers for the UE, thereby efficiently transmitting sharply fluctuated data, and lowering loss of a network and the user equipment while improving user experience.

    Abstract: A method of bearer deletion is provided to improve the universality of the bearer deletion process. The method includes: receiving, by the original intermediate NE, the cancellation type indication parameter sent by the HSS, and deleting the bearer between the serving gateway (S-GW) and a packet data network gateway (P-GW), if the original intermediate network element obtains an attach type according to the cancellation type indication parameter indicating an attach type and a corresponding bearer exists on the original intermediate NE. This method helps efficiently improve the universality of the bearer deletion flow.

    Abstract: A data transmission method provided in embodiments of the present application includes: determining, by a mobility management entity MME, that user equipment UE changes from an unreachable state to a reachable state; sending, by the MME, a request message to a serving gateway SGW; receiving, by the MME, downlink data sent by the SGW; and sending, by the MME, the downlink data to the UE. In this way, when the UE changes to a reachable state for downlink data, the MME requests the SGW to send the downlink data, and the MME then sends the downlink data to the UE, thereby avoiding loss of the downlink data caused by delivery of the downlink data to the UE that is in an unreachable state, and improving real-time accuracy of transmission.

    Abstract: An access control method, including obtaining, by a protocol-stack upper layer of a terminal, an override identifier, starting, by the protocol-stack upper layer of the terminal, an application specific congestion control for data connectivity (ACDC) check according to a service initiated by the terminal, and, if the protocol-stack upper layer of the terminal confirms that the service initiated by the terminal can pass the ACDC check and determines that the override identifier corresponding to an application identifier of the service passing the ACDC check is overriding an access class barring (ACB) check, sending, by the protocol-stack upper layer of the terminal, an radio resource control (RRC) establishment request message to an access layer of the terminal, where the request message carries an indication of not performing an ACB check.

    Abstract: Embodiments of the present invention disclose a bearer handover control device and control method. The method includes: receiving, by a network side device, a bearer handover message; and determining, by the network side device according to the bearer handover message, a bearer needing to be handed over in all bearers, so that an end marker End Marker message is sent to a source base station only for the bearer needing to be handed over. By using the foregoing solutions, for a multi-connection scenario, a network side device can determine a bearer needing to be handed over, so that an end marker message is sent only for the bearer needing to be handed over, which can prevent discarding of subsequent data of a bearer that is not to be handed over, and ensure multiple connections between a UE and base stations, thereby improving stability of a system.
