摘要： Embodiments of the present invention provide a discontinuous reception communication synchronization method and apparatus. The discontinuous reception communication synchronization method in the embodiments of the present invention includes: receiving a paging message delivered by a network element of a core network, where the paging message includes an extended discontinuous reception DRX indicator and/or extended DRX; calculating a paging time according to the extended DRX indicator and/or the extended DRX; and paging a terminal at the paging time. The embodiments of the present invention resolve a problem of extra power consumption caused by that a terminal frequently listens to a paging message during a process of communicating with a network, and also avoid a paging loss caused by that DRX between the terminal and the network is asynchronous.

摘要： A service data transmission method and a device are disclosed, to resolve a problem in the prior art that a network side cannot provide targeted services for different types of NB-IoT services. The method includes: determining, by an access network device, first information of service data to be sent by a terminal, where the first information includes at least one of a service type and a priority; then receiving, by the access network device, the service data sent by the terminal by using a NAS signaling message; and sending, by the access network device, the service data and the first information to a gateway, so that the gateway charges the service data based on the first information after receiving the service data and the first information.

摘要： Embodiments of the present invention provide a coverage enhancement CE function implementation method and a device. The method includes: obtaining, by a first radio access network node, CE authorization information of a terminal, where the CE authorization information includes at least one of the following: CE indication information and an authorized CE level range; and further determining, by the first radio access network node based on the CE authorization information, whether a CE level of the terminal meets an authorization requirement, and controlling, based on an authorization result, use of a CE function by the terminal. It can be learned that, not all terminals can use the CE function, but only an authorized terminal can use the CE function, to ensure that the terminal can use the CE function properly within an authorized range and to improve radio channel resource use efficiency.

摘要： 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.

摘要： A data transmission method provided in embodiments of the present invention 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.
