Embodiment 1

[0020] image 3 It is a schematic flow chart of Embodiment 1 of the present invention. Such as image 3 The shown embodiment 1 of the present invention mainly includes the following steps:

[0021] Step 301 , after the relay UE is turned on, it searches for a base station eNodeB0 that loads the core network according to current cell broadcast information, and completes a random access process to the found base station eNodeB0 .

[0022] Here, the relay UE is pre-designated by the system, and is a UE in an edge area covered by multiple base stations.

Abstract

The invention provides a relay initial registration method. The method comprises the following steps: firstly searching a base station of a load core network by relay UE (user equipment), completing random access at the base station of the load core network, then establishing a connection with the core network, establishing a default bearer, finally further researching the base station without the load core network, completing the random access process with the searched base station, realizing uplink-downlink synchronization, and further sending a specific message before the search of the base station without the load core network to ensure that a link between the relay UE and the base station of the load core network is in a normal state so as to effectively realize the registration of the relay UE in the network.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a relay initial registration method in a multi-channel data transmission system. Background technique [0002] figure 1 It is a schematic diagram of a typical mobile communication system network at present. Such as figure 1 As shown, in an existing mobile communication network, an evolved packet core network (EPC) is connected to a base station (eNB) through an S1 interface; and an eNB is connected to an eNB through a wired X2 interface. Both the data of the S1 interface and the X2 interface are transmitted through the wired network. [0003] Laying a wired transmission network in an existing system is expensive. In relatively remote areas, the number of users is small, and the amount of data transmission is relatively small. Laying high-cost wired transmission networks is a waste of resources. [0004] In view of the above problems, it is currently proposed that in the dat...
