Embodiment Construction

[0081] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0082] The present invention first proposes a wireless access gateway AG. The AG mainly completes the data transmission function in the packet domain, completes the control plane functions of GGSN and SGSN, and can also provide the same control plane interface as GGSN / SGSN. The main functions of this AG include:

[0083] Network access control: It mainly completes the connection of mobile users to the communication network to achieve the purpose of using network services, including authentication and authorization, admission, message filtering, etc. Mobile user access control behaviors can occur on the mobile side or can occur On the fixed side of the network, network access control can complete some specific processes, such as limiting the number of mobile users ...

Abstract

The present invention provides wireless transmission method, system and device. The present invention provides wireless accessing gateway and wireless accessing node, in wireless grouped data network, mobile terminal only through wireless accessing node capable of directly connected with grouped data network, to make grouped data transmission, through wireless accessing gateway making wireless access point administration and data transmission control. Wireless grouped data transfer system can combine with existing wireless communication network, utilizing wireless accessing node directly making communication with grouped data network in transmitting grouped data, in transmitting phonetic etc circuit domain business, through circuit domain service in existing wireless communication network to make transmission; at the same time wireless accessing gateway through grouped data gateway in current network connected with service provider other network, raising said wireless transmission system applicability. The present invention simplifies grouped data network structure, reducing network processing time delay and raising retransmission performance.

Description

technical field [0001] The invention belongs to the field of wireless communication, in particular to a method, system and device for transmitting packet data in a wireless communication network. Background technique [0002] With the vigorous development of Internet services and the wide application of broadband access network and wireless network, high-speed and convenient access to the network is getting widespread attention. At the same time, in order to make better use of existing network resources and better protect the cost of network equipment operators, research on integrating the respective advantages of mobile access networks and fixed access networks is becoming a new hotspot in the communication industry. [0003] figure 1 It shows a schematic diagram of networking of an existing UMTS network, as shown in figure 1 As shown, the UMTS network is composed of a core network (CN, Core Network) and a UMTS terrestrial radio access network (UTRAN, UMTS Terrestrial Rad...
