Problems solved by technology

However, this technology needs to transform the huge GSM network and upgrade the BSC of the GSM network
[0006] To apply the above method in the prior art to switching or reselection between different systems, the specific system must be upgraded or modified
However, the upgrade or transformation of this specific system may sometimes cost a lot, and it is not suitable for popularization and application.

Embodiment Construction

[0029] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated. In the drawings, the same reference numerals denote the same or similar components or elements.

[0030] In this article, the first wireless communication system and the second wireless communication system are different systems, and the multi-mode terminal is a terminal that supports multiple standards, and can switch or reselect between the first wireless communication system and the second wireless communication system . When the multi-mode terminal is in the first wireless communication system, the cell currently serving the multi-mode terminal in the first wireless communication system is called the "current serving cell", and the cell in the second wireless communication system corresponding to the "current serving cell" Adjacent cells are referred to as adjacent cells of the second wireless c...

Abstract

The invention discloses a method and a system for quickly returning a heterogeneous system, a wireless terminal and a wireless network controller. The method comprises the following steps of: receiving quick returning indication information of a second wireless communication system from a first wireless communication system by a multi-mode terminal, wherein the quick returning indication information is used for indicating whether to allow the multi-mode terminal to quickly return to the first wireless communication system from the second wireless communication system and the first wireless communication system and the second wireless communication system are heterogeneous systems; after the multi-mode terminal is switched or reselected to the second wireless communication system, receiving adjacent cell information of the first wireless communication system in the current service cell; and quickly reselecting to the first wireless communication system by the multi-mode terminal according to FRI (Frame Relay Interface) information and of the second wireless communication system and the adjacent cell information of the first wireless communication system. The system has equivalent application effect to the functions and the performance of Fast Return in a GSM R6 (Global System For Mobile Communications For Railway) protocol, avoids the update of BSC(Base Station Controller) in a GSM (Global System for Mobile Communications) and saves a great amount of function update expense for operators.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method, system, wireless terminal and wireless network controller for quick return from different systems. Background technique [0002] Wireless communication networks are widely used to provide various communication services such as telephony, video, data, messaging, and broadcasting. With the development of communication technology, wireless communication network from 2G (2 nd Generation, second generation) communication technology developed to 3G (3 rd Generation, the third generation) communication technology, and LTE (Long Term Evolution, long-term evolution) communication technology. The standardization organization 3GPP (The 3rd Generation Partnership Project, 3rd Generation Partnership Project) promulgated the 3G mobile phone technology UMTS (Universal Mobile Telecommunication System, Universal Mobile Telecommunications System). The network structure of...
