Problems solved by technology

[0004] In the above existing technologies, the random access process requires multiple interactions between the base station and the terminal. Therefore, in the prior art handover process or access process, there is a certain delay in the traditional access process of the UE accessing the site.

Embodiment Construction

[0038] Embodiments of the present invention provide a method, device and system for accessing a site, which are used to speed up the access speed of a UE to a site and reduce the access delay.

[0039] The method for accessing a site in the embodiment of the present invention is aimed at the scenario where the control plane and the user plane of the terminal (UE) are separated. In this scenario, the user plane and the control plane can be switched to different base stations separately. For example:

[0040] In scenario 1, the control plane of the UE remains at the second site, and the transmission of the user plane of the UE is switched from the third site to the first site.

[0041] Wherein, the second site takes a macro base station eNB as an example, the third site takes Pico2 as an example, and the first site takes Pico1 as an example.

[0042] In this scenario, since the coverage of the small base station is relatively small, TA changes are not considered here. Therefor...

Abstract

Disclosed are a method, device and system for accessing stations. The method in the embodiments of the present invention comprises: receiving a first message sent by a second station, the first message containing first configuration information, the first configuration information containing configuration information about a scheduling request (SR), or configuration information about a sounding reference signal (SRS), or configuration information used for sending data; and according to the first configuration information, sending first access information to a first station so as to access the first station to perform communication, the first access information being the SR or the SRS, or ACK or NACK, or the data.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for accessing a site. Background technique [0002] With the development of the mobile communication system, the transmission rate and service quality that the communication system can provide are getting higher and higher, and user services also put forward higher and higher requirements on the transmission rate of the communication system. Third Generation Partnership Project (3 rd The Generation Partnership Project (3GPP) introduced carrier aggregation (CA, Carrier Aggregation) technology, which ensures the transmission rate of the terminal (User Equipment, UE) without greatly increasing the system bandwidth, and at the same time provides UE with higher throughput. quantity. The simultaneous deployment of the small cell and the macro network is one of the important scenarios. In this scenario, the small cell can provide services for...
