Embodiment Construction

[0057] The specific implementation of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0058] The data acquisition method and system of the present invention can provide SCDMA terminal (UT) or TE2 (DTE) connected to SCDMA terminal (UT) to communicate with other public wireless data networks. Among them, due to the connection between SCDMA terminal and public data network The intercommunication belongs to the existing technology and will not be repeated here; the following mainly describes the related content of the intercommunication between the DTE connected to the SCDMA terminal and the public wireless data network.

[0059] Since the current SCDMA system provides a circuit-type bearer service, and this service works in a connection-oriented manner, there are working procedures such as connection establishment, data transmission, and connection release in the process of realizing data collection.

[0060] The data coll...

Abstract

The invention provides a method and system for collecting data in an SCDMA system. The system at least contains BSes, a BSC, an HLR, a data collection device, a GWF and an APP Server; the method contains the following: a plurality of BSes on an ACCO generate a paging request toward a DCE which launches a distribution establishment process of a wireless link on an ACCI; after signaling interactionwith other devices, the BSes transmit allowed information of data transmission to the DCE; then data transmission is conducted between the DCE and a DTE; upon receipt of data transmitted by the BSC, the GWH transmits the data to the APP Server through an SLa interface. By adopting the invention, transmission interference of multi-paths is avoided; accurate receiving and realizing in-phase CDMA isensured; interference among multiple accesses is reduced; system capacity is increased; the problem of aero link blockage caused by large capacity of data collection and short time of burst communication in a single time is prevented.

Description

technical field [0001] The invention relates to a data collection method and system, in particular to a data collection method and system for realizing data collection in an SCDMA system. Background technique [0002] At present, there are many methods of using public wireless networks for data collection, for example, using GSM / GPRS and CDMA1x networks for data collection. [0003] GPRS (General Packet Radio Service) is a new type of packet data transmission service opened on the existing GSM network, which allows multiple users to share some fixed channel resources. GPRS is suitable for intermittent, sudden or frequent, a small amount of data transmission, and is also suitable for occasional large data transmission. ", "free switching" advantages. At present, due to the advantages of wide coverage of GSM network, no need to set up base stations, and functions such as voice / short messages, more and more terminals adopt GSM / GPRS for data collection. From the point of vie...
