Example Embodiment

[0028] The present invention applies to figure 1 The WCDMA and TD-SCDMA mixed networking environment shown. see figure 1 , in the networking of the two standards, the equipment serving GPRS support node (SGSN, Serving GPRS Support Node) and the gateway GPRS support node (GGSN, Gateway GPRS Support Node) 160 in the core network packet domain, the equipment mobile switching in the core network circuit domain Both the mobile switching center (MSC, Mobile Switching Center) 150 and the radio network controller (RNC, Radio Network Controller) 140 of the access network are shared by the two systems. The difference between the two systems lies in the use of different base station equipment. The Node B (Node B) base station 130 is used for the WCDMA system, and the base transceiver station (BTS, Base Transceiver Station) 120 is used for the TD-SCDMA system. User Equipment (UE, User Equipment) 111 , 112 and 113 are dual-mode terminals and support both WCDMA and TD-SCDMA systems.

Abstract

The invention discloses an allocation method for business load in mixed network of WCDMA and TD-SCDMA, which comprises: user device initiates communication business access request by base station; the wireless network controller determines the type of access base station according to required business type and network resource condition and whether accorded with said bearing access base station; if yes, notifies user access success, the latter completes communication business; or else, notifies user device to bear the base station by it self and bearing access base station to bear user device business, and the user device also completes communication business. This invention increases bandwidth utility of mixed network.

Description

technical field [0001] The invention relates to a mixed networking of different 3G systems, in particular to a service bearer distribution method in a WCDMA and TD-SCDMA mixed network. Background technique [0002] In the third-generation mobile communication era, there are three international standards: WCDMA (Wide-band Code Division Multiple Access, wideband code division multiple access), CDMA2000 (Code Division Multiple Access 2000, code division multiple access two thousand) and TD-SCDMA (Time Division Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access), in which WCDMA inherits the development of GSM (Global System for Mobile Communication, Global System for Mobile Communication), CDMA2000 inherits the development of CDMA IS-95, TD -SCDMA is a 3G standard proposed by the domestic CWTS (China Wireless Telecommunications Standard Group, China Wireless Telecommunications Standard Research Group). WCDMA and CDMA2000 are FDD (...
