Embodiment Construction

[0048] In the embodiment of the present invention, a common base station (as a relay base station) and a common terminal (as a relay terminal) are used to construct a relay device, and the relay terminal provides the relay base station with a backhaul channel (backhaul) connected to the core network through a wireless interface. ). Specifically, after the data packet to be sent by the relay base station is encapsulated by Internet Protocol (Internet Protocol, IP), and then sent to the donor base station via the relay terminal, the donor base station is on the same network as the IP address of the relay terminal through the IP address. The first core network device in the segment sends it to the relay server, and the relay server performs IP decapsulation on the data packet and sends it to the second core network device whose IP address is in the same network segment as the IP address of the relay base station. The core network equipment sends to the Internet (Internet). Corre...

Abstract

The invention relates to the field of communication technologies, in particular to a relay device, a relay server and a relay method, which are used for solving the problems that the implementation complexity of relay equipment is high and a donor base station needs to be transformed greatly in the prior art. The relay method provided by the embodiment of the invention comprises the steps that: an IP encapsulation and de-encapsulation module performs IP encapsulation on a data packet to be transmitted of a relay base station and then transmits the data packet to a signal transceiving module; and the signal transceiving module at a relay terminal receives the data packet after IP encapsulation and transmitted by the IP encapsulation and de-encapsulation module, then transmits the data packet after IP encapsulation to the relay server through the donor base station and first core network equipment, and the first core network equipment performs IP de-encapsulation on the data packet and then transmits the data packet to second core network equipment. An IP address of the first core network equipment and an IP address of the relay terminal belong to a same IP network segment, and an IP address of the second core network equipment and an IP address of the relay base station belong to a same IP network segment.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a relay device, a relay server and a relay method. Background technique [0002] In the wireless mobile communication network before the relay (Relay) technology of the fourth generation (4th Generation, 4G) appeared, the wireless base station equipment provided the base station to the wireless network controller or The transmission of the core network, the communication process between the user terminal (UE) and the wireless network is usually as follows: the user terminal accesses the wireless base station equipment through the air interface (such as Uu interface), and the wireless base station equipment provides the information through wired transmission or point-to-point microwave The backhaul (backhaul) link is further connected to the core network (CN, coreNetwork) where the wireless network controller is located; the core network then routes or forwards t...
