Abstract

The invention discloses a method for accessing a base station, a base station and user equipment, belonging to the technical field of communication. The method comprises the following steps of according to an access request of user equipment, establishing a control surface connection with the user equipment by a current macro base station, and distributing a first cell wireless network temporary identification for the user equipment; and when a micro base station measurement report reported by the user equipment is received, selecting a micro base station for the user equipment according to a preset strategy, so that a data surface connection can be established for the user equipment and the micro base station, and the micro base station is notified of the context information of the user equipment, wherein the context information comprises the first cell wireless network temporary identification distributed to the user equipment. The base station comprises a control surface connection establishing module and a first identification maintenance module. The user equipment comprises a control surface connection establishing module and a data surface connection establishing module.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for accessing a base station, a base station and user equipment. Background technique [0002] In the second-generation communication system, the user's information exchange needs are mainly voice calls and short messages, which do not require high spectrum efficiency. The system is mainly limited by the size of the coverage area, so the macro base station is generally used. The spacing is generally large, and the cost of this networking method is low. However, with the development of the third and fourth generation communication systems, data transmission has become a new requirement, especially for real-time video transmission, the requirements for spectrum efficiency and network throughput have increased significantly, but due to the large coverage of macro base stations to accommodate users Many, so that the throughput of the macro base station is gre...
