Embodiments of this application relate to the communications field, and in particular, to an information indication method and apparatus in the communications field. The embodiments of this application include: generating a PPDU including radar indication information, where the radar indication information is used to indicate that the PPDU is a PPDU used for radar testing, and transmitting the PPDU. According to the method provided in the embodiments of this application, the transmit end explicitly indicates that the PPDU is a PPDU used for radar testing rather than a PPDU used for communication between communications devices. When a receive end receives the PPDU, the receive end no longer monitors a channel, thereby reducing power consumption of the receive end.

Information indication method and apparatus

An information transmission method and a network device, the network device including a transceiver, a processor, and a non-transitory storage medium storing a computer program for execution by the processor. The computer program includes instructions to receive a first frame through the receiver, where an extended schedule element of the first frame has a field indicating communication between network devices is supported, and where the extended schedule element further has a source association identifier and a destination association identifier, and control the transceiver to transmit information to a first network device when both the first network device and the network device support communication between network devices, where a value of the source association identifier and a value of the destination association identifier are each 0.

Information transmission method and network device

Embodiments of this application provide an information transmission method and a network device. The method may include: listening, by a second network device, to a first frame sent by a first network device, where the first frame is used to indicate whether the first network device supports communication between network devices; and if both the first network device and the second network device support the communication between the network devices, transmitting, by the second network device, information with the first network device.

A base station handover method and system for a communication system are provided. The method includes: a serving base station triggering a bi-casting operation according to information reported by a user equipment, adding a communication context of a target base station into a Mobile Management Entity (MME), and the MME notifying a Serving GateWay (SGW) to store two communication routes; the SGW communicating with the serving base station and the target base station after the triggering of bi-casting is completed; and the serving base station interacting with the user equipment, and handing over the user equipment from the serving base station to the target base station. By means of the technical scheme according to the embodiments of the present document, the complexity of base station handover can be reduced, the efficiency of base station handover can be increased, and at the same time the practicability is enhanced.

Base station handover method and system for communications system

The present invention discloses a method and an apparatus for establishing a service route, wherein the method comprises the steps of: collecting, by a control station, channel quality information of all links on each path of a terminal; according to the channel quality information, selecting an access station which establishes a route with the terminal. The present invention realizes selecting the access station which establishes a route with the terminal according to the actual application situation.

Method and apparatus for establishing service route

Embodiments of the present invention disclose Wireless Mesh Network (WMN) for notifying proxy update. By constructing the proxy update add message, where the proxy update add message includes the address of terminal, the current proxy node address after terminal switching and the destination node address of the terminal, and taking the address of the original proxy node before terminal switching as the address of the destination node, and sending the proxy update add message constructed to the original proxy node, where the proxy update add message is used for updating proxy information of the terminal in the proxy information table of the original proxy node to be the current proxy node address. It makes sure that packets received by the original proxy node which should be sent to the terminal could be received by the terminal, and packet loss rate during terminal switching could be reduced.

Method, node, and system for notifying proxy update in WMN

Embodiments of the present invention disclose a method and node for notifying proxy update in a WMN and a WMN for notifying proxy update. By constructing the proxy update add message, where the proxy update add message includes the address of terminal, the current proxy node address after terminal switching and the destination node address of the terminal, and taking the address of the original proxy node before terminal switching as the address of the destination node, and sending the proxy update add message constructed to the original proxy node, where the proxy update add message is used for updating proxy information of the terminal in the proxy information table of the original proxy node to be the current proxy node address. It makes sure that packets received by the original proxy node which should be sent to the terminal could be received by the terminal, and packet loss rate during terminal switching could be reduced.
