Problems solved by technology

The existence of the common channel on the data base station is also a considerable expense. Not only may it cause interference to other base stations, but the high energy consumption is also a factor that cannot be ignored

Embodiment Construction

[0043] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0044] Such as figure 1As shown, the communication system based on the technical solution of the present invention includes: a signaling base station, a plurality of data base stations communicatively connected with the signaling base station, and further, the signaling base station and the data base station are communicated through the Xn interface, based on In the ultra-dense coverage scenario of small base stations in the future, the distance between the signaling base station and the data base station is very close, and the delay and throughput of Fiber Channel are close to the ideal situation. The interaction between the two through the Xn interface has no delay and capacity limitations. The terminal communicates with the signaling base station thro...

Abstract

Embodiments of the present invention provide a method and a device for accessing a base station, a base station and a communication system. The method comprises the steps of: acquiring signaling access information of a terminal accessing a signaling base station; synchronizing the signaling access information to a plurality of data base stations in communication connection with the signaling base station, acquiring service connection information subsequently transmitted from the terminal to the signaling base station according to the signaling access information by the plurality of data base stations, and acquiring uplink access information of the terminal according to the service connection information; and selecting one data base station from the plurality of data base stations according to the uplink access information of the terminal, so as to enable the terminal to directly access the selected data base station. The scheme of the method of the present invention is short in time delay, and reduces the possibility of signaling congestion.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for accessing a base station, a base station and a communication system. Background technique [0002] Currently, the 3GPP (3rd Generation Partnership Project) standard organization RAN2 group is studying small cell enhanceme (small cell nt related projects) for the LTE long-term evolution R12 version. This project discusses network deployment, resource coordination, signaling overhead, symmetry of uplink and downlink services, and mobility issues that need to be considered in scenarios where network traffic grows massively and small base stations are ultra-densely deployed in the fifth-generation mobile communication system. Alleviate the current and future exponential growth of network traffic pressure and a large number of indoor data business needs. [0003] Small cells (small base stations) can effectively transfer the business traffic of macro cell...
