Problems solved by technology

The handover between these base stations, unlike the LTE system, can exchange load information between base stations through the X2 interface, so the handover request has a certain degree of blindness, and the handover failure rate will be higher

Embodiment Construction

[0035] A multi-standard base station refers to a base station that supports multiple RATs, and can be obtained through a migration mode or a common mode. The migration mode refers to the improvement of the existing base station supporting a certain RAT, so that it can also support other RATs and become a multi-standard base station supporting multiple RATs. For example, adding a single board to the slot of the existing GSM base station Or change the existing single-board software to make the base station also support WCDMA technology, and become a multi-mode base station where GSM base station and NodeB coexist. The migration mode can be understood as: different base station network elements are obtained through configuration and management of physical resources on the base station. The general mode refers to the construction of a brand new network device node. According to the configuration, the device node can generate different base stations for different physical resource ...

Abstract

The invention discloses a system and a method of multi-standard base station interconnection, wherein, multi-standard base stations are connected by means of uniform interface units which provide basic physical transport bearing and uniform transport protocol stacks, namely, uniform logic interfaces, which are used for transporting high-level application protocols to support the information interaction among multi-standard base stations, even among base station child nodes inside each multi-standard base station, such as load information, resource using information, interference information, switch process signaling messages, data forwarding and so on. The high-level application protocols born in the uniform transport protocol stacks are primarily user plane protocols and control plane protocols. The realizing function of the interface units is also provided among all the base station child nodes inside the multi-standard base stations. As the interface units which are internally provided by the multi-standard base stations adopt uniform transport protocol stacks, the system performance can be radically improved if similar uniform logic interfaces are provided among the multi-standard base stations.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a system, a base station and a method for multi-mode base station intercommunication. Background technique [0002] With the development of wireless communication technologies, more and more radio access technologies (Radio Access Technology, RAT) are applied. These different RATs include Global System for Mobile Communications (Global System for Mobile, GSM) technology, Wideband Code Division Multiple Access (WCDMA) technology, World Interoperability for Microwave Access (WiMax) technology, Long Term Evolution (Long Term Evolution, LTE) technology, Air Interface Evolution (Air Interface Evolution, AIE) technology, Code Division Multiple Access (Code Division Multiple Access, CDMA) 2000 technology, and so on. These different wireless access technologies constitute base station systems of different standards. For example, in GSM technology, the base station is calle...
