Problems solved by technology

[0009] However, the current technology still has the following problems: 1. Once the PGW of the MRN is anchored, it cannot be replaced, which causes the signaling and data of all remote UEs served by the MRN to be routed through the PGW of the MRN, which will cause a data transmission path 2. In the scenario where cells change frequently, MRN needs to perform a large number of cell measurements and reports, which increases the signaling burden of the air interface

Abstract

The invention discloses a wireless communication establishment method in a mobile relay and a network device. The method comprises the steps that the mobile relay establishes control plane connection with a core network through a first macro base station, wherein the control plane connection is used for supplying control plane information transmission to UE accessing the mobile relay; and the mobile relay establishes user plane connection with a scanned first small cell base station, wherein the user plane connection is used for supplying user plane information transmission to the UE accessing the mobile relay. The new wireless communication method is provided. The high-rate data transmission of the mobile terminal can be realized in a high-speed moving scheme.

Description

technical field [0001] The present invention relates to the communication field, in particular to a mobile relay-based wireless communication establishment method and network equipment. Background technique [0002] In recent years, my country's high-speed railway has achieved rapid development. It is estimated that by 2020, China's high-speed railway construction mileage of 200 kilometers per hour and above will exceed 18,000 kilometers, accounting for more than half of the world's total mileage of high-speed railways. In the high-speed railway environment, due to the Doppler effect caused by high-speed movement, the center frequency of the wireless signal shifts, causing the deterioration of the wireless channel environment, and the high-speed movement has stricter time requirements for mobile user access and handover, which is prone to mobile network coverage There are a series of problems such as insufficient overlapping areas, decreased handover success rate, and access...
