  • Publication number: 20180027429
    Abstract: Embodiments of the present disclosure provide a data transmission method, including: receiving, by a first user equipment (UE), a first message sent by a second UE, where the first message includes indication information that the second UE is capable of acting as a relay UE; and performing, by the first UE, data transmission with a base station via the second UE, where the second UE acts as a relay UE. In embodiments of the present disclosure, when first UE is unable to directly perform data transmission with a base station, the first UE uses second UE as a relay UE according to indication information sent by the second UE that the second UE is capable of acting as a relay UE, and then is unable to perform data transmission via the relay UE. Therefore, a success rate of data transmission can be ensured, and further transmission efficiency can be increased.

  • Publication number: 20170223755
    Abstract: Embodiments of the present invention relate to an RRC connection method and a serving node. In the embodiments, an RRC connection is established between an anchor node and a UE. Therefore, when a serving node of the UE is switched, a connection between an MME and the anchor node does not change. When the MME needs to send a paging message, the MME does not need to send the paging message to all base stations in a TA area that corresponds to the paging message, thereby effectively reducing signaling load of a core network.
