[0002] With the development of wireless communication technology, a relay function for wearable devices is being introduced in wireless communication systems, which mainly refers to the function of a remote terminal (e.g., a wearable device) transmitting data through a relay terminal (e.g., a mobile phone terminal). In this function, the relay terminal helps the remote terminal complete data transmission.

[0003] Since the remote terminal communicates with the network equipment (for example, base station, core network equipment) through the relay terminal, the network equipment cannot communicate directly with the remote terminal. When there is downlink data of the remote terminal, how the network equipment sends a paging message to the remote terminal device, and then ensures the correct transmission of the downlink data of the remote terminal is a technical problem that needs to be solved urgently. Summary of the invention

[0087] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0088] Figure 1 Schematic diagram of a communication system using a data transmission method of the present application. Figure 1 As shown, the communication system 100 includes a remote terminal device 110, a relay terminal device 120, an access network device 130, a control plane network element 140, a forwarding plane network element 150, and a data network 160. In addition, those skilled in the art can understand that different devices in the communication system 100 communicate with each other through interfaces.

[0089] The remote terminal device 110 can perform data transmission through the relay terminal device 120. For example, when the access network device 130 receives downlink data for the remote terminal device 110, it can send a paging message to the remote terminal device 110 through the relay terminal device 120. Optionally, in the embodiment of the present application, the remote terminal device 110 includes but is not limited to a wearable device, a smart refrigerator, and a smart air conditioner. For example, the wearable device may include a smart bracelet, a smart helmet, etc.

[0090] The relay terminal device 120 can establish a user plane connection with the access network device 130 through a bearer, and can also establish a communication signaling connection with the control plane network element 140 through an interface. It should be understood that the relay terminal device 120 can communicate with multiple remote terminal devices 110. Optionally, in an embodiment of the present application, the relay terminal device 120 includes but is not limited to an access terminal, a user equipment (User Equipment, UE), a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile terminal, a user terminal, a terminal, a wireless communication device, a user agent or a user device. The access terminal can be a cellular phone, a cordless phone, a Session Initiation Protocol (Session Initiation Protocol, SIP) phone, a Wireless Local Loop (Wireless Local Loop, WLL) station, a Personal Digital Assistant (Personal Digital Assistant, PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a terminal device in the Internet of Things, a virtual reality device, a terminal device in a future 5G network, or a terminal device in a future evolved public land mobile network (Public Land Mobile Network, PLMN), etc.

[0091] The access network device 130 may be a device that communicates with the relay terminal device 120, such as a base station or a base station controller. However, it is understood that the access network device 130 may communicate with any number of terminal devices similar to the relay terminal device 120. The access network device 130 may also communicate with the control plane network element 140 through an interface. Similarly, the access network device 130 may also communicate with the forwarding plane network element 150 through an interface. Each access network device may provide communication coverage for a specific geographical area, and may communicate with terminal devices (such as UE) located in the coverage area (cell). The access network device may support communication protocols of different standards, or may support different communication modes. Optionally, the access network device 130 can provide wireless access services for terminal devices. For example, the access network device 130 may be an evolved Node B (eNodeB), or a Wireless Fidelity Access Point (WiFi AP), or a Worldwide Interoperability for Microwave Access Base Station (WiMAX BS), or a wireless controller in a cloud radio access network (Cloud Radio Access Network, CRAN), or may be a network device in a future 5G network or a network device in a future evolved public land mobile network (Public Land Mobile Network, PLMN), etc.

[0092] The control plane network element 140 is responsible for the mobility management and forwarding path management in the communication system 100, such as sending a message forwarding policy to the forwarding plane network element 150, instructing the gateway forwarding plane (Gateway User Plane, GW-U) to process and forward the message according to the message forwarding policy. The control plane network element 140 can be all or part of the control function formed by the Software Defined Network (SDN) controller, the Gateway Control Plane (Gateway Control Plane, GW-C), the Mobility Management Entity (Mobility Management Entity, MME) or the above network elements after fusion. Among them, the software defined network technology provides an effective way to solve the bottleneck problem of gateway signaling processing. By further separating the control plane interface signaling processing function and the user plane forwarding data function of the gateway, the interface signaling processing function is placed on a general computing platform to become a control plane network element (Control Plane, CP), and the user plane forwarding data function is placed on a dedicated hardware platform to become a forwarding plane network element (User Plane, UP). The control plane network element 140 can also be divided into a mobility management network element and a session management network element, wherein the mobility management network element is responsible for the mobility management of the terminal device, such as the terminal device attaching to the network, the location change of the terminal device, etc., and the session management network element is responsible for the session management of the terminal device, such as session establishment, modification, release, etc. In addition, by decoupling the control and forwarding of the gateway device, the design of the hardware platform is greatly simplified, the cost of the hardware platform is reduced, and it is conducive to accelerating the deployment of the mobile packet data network. MME is mainly responsible for the mobility management and session management of the control plane, such as user authentication, switching, mobility management of idle terminals, user context and bearer management, etc.

[0093] The forwarding plane network element 150 is responsible for message processing and forwarding. The forwarding plane network element 150 can be a physical or virtual forwarding device such as a forwarding plane function of a P-GW, a forwarding plane function of an S-GW, a router, or a switch.

[0095] The remote terminal device 110, the relay terminal device 120 or the access network device 130 may be a wireless communication transmitting device and / or a wireless communication receiving device. When transmitting data, the wireless communication transmitting device may encode the data for transmission. Specifically, the wireless communication transmitting device may obtain (e.g., generate, receive from other communication devices, or store in a memory, etc.) a certain number of data bits to be sent to the wireless communication receiving device through a channel. Such data bits may be included in a transmission block (or multiple transmission blocks) of data, and the transmission block may be segmented to generate multiple code blocks.

[0096] In addition, the communication system 100 may be a public land mobile network (PLMN) network or a D2D (Device to Device) network or an M2M (Machine to Machine) network or other networks.

[0105] Optionally, the indication message is a system message or a radio resource control RRC dedicated signaling.

[0106] Therefore, in the wireless communication method of the embodiment of the present application, the network device instructs the first terminal device to listen to the paging message of the second terminal device at the paging time of the first terminal device through an indication message, or instructs the first terminal device to listen to the paging message of the second terminal device at the paging time of the second terminal device. Thus, the network device can accurately send the paging message of the second terminal device through the first terminal device, thereby ensuring the correct transmission of the downlink data of the second terminal device.

A network device receives a status update message from a first terminal device, where the status update message is used to request the network device to update link status information between the first terminal device and a second terminal device, where the second terminal device communicates with the network device through the first terminal device.

[0109] Optionally, when the first terminal device establishes a link connection with the second terminal device, the first terminal device sends the status update message to the network device.
