Embodiment 1

[0025] Such as image 3 As shown, Embodiment 1 of the present invention proposes a flat GSM network architecture, including AU and GU, wherein the AU is used to connect with the GU through an IP network, and bears the information used to establish the general packet radio service GPRS business process. Ordering and transmission of GPRS service data The RLC / MAC protocol processing layer in the AU manages the wireless resources used to transmit the signaling for establishing GPRS service procedures and the establishment and removal of GPRS air interface links.

[0026] The GU is used to connect with the AU through the Internet Protocol IP network, bears the signaling for establishing the GPRS service flow of the general packet radio service and transmits the GPRS service data.

[0027] Wherein, GU can be but not limited to gateway device or BSC node, preferably, GU is FEMTO gateway; AU can be but not limited to base station, access device or BTS node, preferably, AU is FEMTO CEL...

Embodiment 2

[0117] Correspondingly, Embodiment 2 of the present invention proposes an access method for GPRS service data transmission, including:

[0118] The access device is connected to the GU through the IP network, and the IP network bears the signaling for establishing the GPRS service process and transmits the GPRS service data. The RLC / MAC protocol processing layer in the access device is used to manage and transmit the signaling for establishing the GPRS service process Commanded wireless resources and GPRS link establishment and teardown.

[0119] Specifically, before establishing GPRS service process signaling, the BG-NS protocol processing layer in the access device requests the GU to register the GPRS cell; and after successfully requesting the GU to register the GPRS cell, the BG-NS protocol processing layer in the AU A request is made to the Serving GPRS Support Node SGSN to register the GPRS cell. Wherein, the access device requests the GU to register a GPRS cell, includ...

Abstract

The invention discloses a GPRS (General Packet Radio Service) business data transmission method, a GPRS business data transmission device, and a GPRS business data transmission system. The method includes the following steps: an access unit (AU) and a gateway unit (GU) are in network connection through the Internet Protocol (IP), so as to carry signaling for setting up a GPRS business process and transmit GPRS business data; an RLC / MAC (Radio Link Control / Media Access Control) protocol processing layer in the AU manages wireless resources for transmitting the signaling for setting up the GPRS business process, as well as the establishment and dismantling of a GPRS air interface link. The invention adopting the technical scheme has the advantage that after the network flattening of a base station subsystem is achieved, the transmission reliability of signaling data and user data on the IP network can be improved better, and the problems of a larger user data transmission delay and disorderly data packets are solved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a general packet radio service GPRS service data transmission method, an access device, a gateway device and a system. Background technique [0002] In the Global System of Mobile Communication (GSM, Global System of Mobile Communication), the network architecture of the Base Station Subsystem (BSS, Base Station Subsystem) is composed as follows figure 1 As shown, it includes a base transceiver station (BTS, Base Transceiver Station), a base station controller (BSC, Base Station Controller) and a transcoding and rate adaptation unit (TRAU, Multi-channel Transcoder Rate Adapter Unit). Wherein, the base station subsystem is directly connected with a mobile station (MS, Mobile Station) through a wireless interface Um for wireless transmission, wireless resource management and wireless link monitoring. The base station subsystem is connected to the mobile switching cent...
