Fig. 1 is a flowchart of an embodiment of a subscriber group-based relay communication method of the present invention. As shown in fig. 1, the present invention relates to the field of network configuration, and is a method for a relay communication method based on a user group. The flow of the invention comprises the following steps:

S120, a relay communication group is established according to the alternative communication equipment set, wherein the relay communication group comprises a relay node and at least one receiving node, and the relay nodes in the same relay communication group and the receiving nodes realize relay communication. In this embodiment, the set of alternative communication devices is a set of all communication devices that communicate with the network device within a coverage area of the same network device, and by obtaining alternative communication devices with network quality parameters lower than a first preset threshold value in the set of alternative communication devices as receiving nodes, relay communication is implemented by using an alternative communication device with network quality parameters higher than a second preset threshold value as a relay node on the basis of each receiving node, so that a relay communication group is established with the alternative communication devices that mutually implement relay communication. The relay node and the receiving node both have a D2D communication function, and can support communication using a D2D technology and report to the network.

And S130, the network only maintains the first data link to the relay node, and the relay node establishes a second data link to the receiving node in the relay communication group. At this time, the network and the alternative communication device as the receiving node perform adjustment of the data link based on the current network quality of the communication device, the current location of the device, the use tag of the device user, and the like. The method comprises the following steps:

A method of adjusting a data link may be: the standby communication equipment with the network quality parameter higher than a second preset threshold value is used as a relay node, and the adjustment strategy is realized based on the network: the network sends different downlink control information (DCI, downlink Control Information) through a PDCCH channel, and the network instructs the relay node to initiate D2D communication Group invitation in a GO (P2P Group Owner) role, instructs the receiving node to receive D2D communication Group invitation initiated by the nearby area GO in a GC (P2P Group Client) role, and after confirming that at least one receiving node successfully joins the D2D communication Group, switches the subsequent service of the receiving node to the D2D communication Group for continuous transmission, where both the relay node and the receiving node can implement D2D communication functions, support communication using D2D technology, and report the network, but not limited thereto.

Another method of adjusting the data link may be: strategy based on terminal self-assembly D2D communication group realization: the relay node sends a request for constructing a D2D communication group to the network based on the cellular signal condition environment and the own D2D group main communication requirement, and the network is based on the following steps: and selecting a GO (P2P Group Owner) and GC (P2P Group Client) terminal list applicable to D2D relay communication based on the conditions of terminal wireless link quality, physical position, mobile service type, application interest preference, user social relationship and the like, wherein the relay node and the receiving node can realize a D2D communication function, support communication by using a D2D technology and report the network, but the method is not limited to the method. And realizing the strategy of D2D communication group communication, and sending confirmation information after judging that the strategy meets the GO condition. After receiving the reply, the relay node sends out an invitation for establishing the D2D communication group in the GO role, and after receiving the invitation, the receiving node in the area actively joins the D2D communication group in the GC role and sends information to the network to request the network to switch the subsequent service to the D2D communication group for continuous transmission, but the method is not limited to the method.

In this embodiment, a data transmission link between the first communication device in the relay communication group and the second communication device of the receiving node is established and the device-to-device D2D is established. Through the steps, the relay communication group is quickly established in the set of the establishment standby communication equipment through simple and convenient steps, the time for switching the communication modes is shortened, and the user experience is improved.

In a variation, the method further includes selecting a list of GO (P2P Group Owner) terminals and GC (P2P Group Client) terminals suitable for D2D relay communication according to conditions such as terminal wireless link quality, physical location, mobile service type, application interest preference, and user social relationship, and combining the list into a D2D relay communication pairing Group, but not limited thereto. The D2D (Device-to-Device) communication technology refers to a communication manner in which two peer user nodes directly communicate with each other. In a distributed network of D2D communication subscribers, each subscriber node is capable of transmitting and receiving signals and has an automatic routing (message forwarding) function. Participants of the network share a portion of the hardware resources they possess, including information processing, storage, and network connectivity, among others. These shared resources provide services and resources to the network that can be accessed directly by other users without going through intermediate entities. In a D2D communication network, user nodes act as both servers and clients, and users are aware of each other's presence, forming a virtual or actual community, self-organised.

D2D communication is a key technology in 4G technology, and, compared with other direct technology that does not depend on infrastructure, D2D is more flexible, and can perform connection and resource allocation under control of a base station, and also can perform information interaction when there is no network infrastructure, and recently, a relay situation is proposed, and a user in the situation of no network coverage can use a user device in the network coverage as a springboard, so as to access the network.

The D2D communication has been developed continuously, and has exceeded the limitations of the initial definition, so as to meet various emerging service demands, such as advertisement push, large-scale activity data sharing, information sharing among friends, and the like. The D2D has obvious technical characteristics, compared with similar technologies, the biggest advantage is that the D2D works in a licensed frequency band, and as a supplement to the LTE communication technology, the D2D uses a frequency band of a cellular system, so that both parties of communication can ensure quality of experience (QoS) of users even after the communication distance is increased, and instead, the WiFi-dirset and other technologies tend to have certain interference after the communication distance is increased. Because the D2D communication distance is relatively short, the channel quality is high, and the high transmission rate, the low time delay and the low power consumption can be realized, and the duration of the mobile phone is prolonged.

Besides the aspects, the D2D can also meet the requirement of a large amount of information interaction among people, compared with Bluetooth, the D2D does not need complicated matching, the transmission speed is faster, and compared with free Wi-FiDirect, the method has better OoS guarantee.

D2D communication technology has different applications in different networks, such as P2P (Peer to Peer) in an Adhoc network, M2M (Machine to Machine) in the internet of things, etc. There is no great essential difference between these different terms, but only that the terms are appropriately adjusted in the respective application scenario to meet their particular needs. Current Mesh networks (Mesh networks), also known as multi-hop networks, are distributed networks composed of D2D communication subscribers. The "multi-hop" is referred to herein as a "single-hop network" where users communicate with each other in a conventional wireless local area network, requiring access to a fixed Access Point (AP). In current cellular network communications, users must also communicate with each other via a central node base station to relay messages between each other. D2D communication will also be popular in future 5G networks to properly alleviate the problem of lack of spectrum resources in wireless communication systems.

The invention adopts the fusion of the network and the D2D relay: in the coverage area of the cellular wireless network, the network performs accurate D2D grouping according to the current wireless link environment and in combination with the conditions of the service type, the application preference, the social relationship and the like of the terminal user, so that the network throughput capacity and the spectrum efficiency in the area are effectively improved. And based on the mobility of the terminal and the D2D relay demand willingness, the GO or the network dynamically adjusts the D2D transmission group, invites or accepts that the off-network terminal which is not in the coverage area of the cellular wireless network temporarily becomes the GC in the D2D transmission group, further expands the wireless coverage area of the cellular network, and improves the perception of users.
