Abstract: A resource scheduling method includes: obtaining, by a terminal device, a first resource configuration parameter from an access network device; determining, by the terminal device, whether a first logical channel (LCH) supports the first resource configuration parameter, where the first LCH is an LCH on which there is to-be-sent data; and if the first LCH supports the first resource configuration parameter, determining, by the terminal device, a resource of the first LCH based on the first resource configuration parameter. According to a resource scheduling method provided in this application, after obtaining the first resource configuration parameter, the terminal device determines the resource of the first LCH by determining whether a mapping relationship exists between the first LCH and the first resource configuration parameter, to map the first LCH to the resource that matches the first LCH. This improves resource utilization.

Abstract: The present invention provides user equipment and a method for ensuring continuous service reception in a wireless network. User equipment (UE) obtains configuration information of a neighboring cell; the UE determines that at least two cells of all cells including the serving cell and the neighboring cell belong to a same area to which a same multimedia broadcast multicast service belongs; and during measurement of a reference signal, the UE combines reference signal measurement values of at least two cells that belong to the area of the same multimedia broadcast multicast service to obtain a combined measurement value, and compares the combined measurement value with a measurement value of another cell, so as to determine whether to perform reselection. Therefore, in a handover determining process, radio signal quality of a single cell is prevented from being underestimated, so that an unnecessary handover procedure is avoided, thereby ensuring quality of a radio signal obtained by UE.

Abstract: A method for serving node establishment includes sending, by a network device, information about a micro network time-frequency resource pool to a terminal; and sending measurement configuration information to the terminal. The measurement configuration information instructs the terminal to serve, when the terminal determines that the terminal meets a preset condition of a first measurement event, as a first serving node to send exclusive information of the first serving node on a first time-frequency resource in the micro network time-frequency resource pool according to the information about the micro network time-frequency resource pool, and the first measurement event is any one of the at least one measurement event.

Abstract: A network terminal device communication method is provided. After a wireless terminal device establishes an RRC connection to a base station, a control plane connection to an MME, and a user plane bearer with a P-GW, the base station determines that a network terminal device uses a user plane bearer between the base station and the P-GW, which is established by the wireless terminal device to transmit user plane data of the network terminal device. The base station releases an air interface connection between the wireless terminal device and the base station, or the wireless terminal device enters a power saving state.
