Method for switching access terminal between signaling wireless network controllers

Abstract

The invention relates to the field of wireless communication and discloses a method for switching an access terminal among signaling wireless network controllers, thus being capable of realizing the switch function in the SRNC under the condition of using only one SRNC special route. When in switch in the SRNC, various eBS modify a route mapping relation table in an activation set of an AT to be switched, the SRNC special route of the AT is modified to an ANID of the target SRNC from the corresponding ANID and then the AT passes through a signaling route transmitted by the SRNC special route to the target SRNC according to the route mapping relation table after the modification. When the AT receives a UAT1 message which is re-assigned by the AT of the target SRNC, the route mapping relation table is modified, and the SRNC special router of the AT is modified to the ANID of the SRNC by the corresponding ANID. The method can issue the switch in the SRNC by the service eBS of the AT or the source SRNC.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to switching technology. Background technique [0002] At present, the third-generation mobile communication technology is gradually becoming mature and commercially available. The Code Division Multiple Access 2000 (Code Division Multiple Access 2000, referred to as "CDMA2000") proposed by the 3rd Generation Partnership Project 2 (3GPP2 for short) 1X data optimization Evolution (1XEvolution-Data Only, referred to as "1XEV-DO") can provide a competitive wireless access system in the next few years. However, in order to maintain the competitiveness in the next decade or decades, it is necessary to introduce new wireless access technologies. At present, the industry has reached a preliminary agreement on the evolution of 3GPP2 air interface technology, which is mainly divided into two stages. The first stage adopts multi-carrier EVDO technology, and more consideration is given t...

Problems solved by technology

Since the route ID of 0×1001 has been used by the source SRNC, that is, the source SRNC has used the unique SRNC-specific route, it is impossible for the AT to assign this route ID to the target SRNC, so the target SRNC cannot be added to the AT before handover Activation is centralized, so that the handover between SRNCs cannot be completed through the existing technology, which means that the existing technology is an incomplete solution
