System) GPRS (General Packet Radio Service, general packet radio service) networks and
UMTS (Universal Mobile Telecommunications System, UMTS)
PS (Packet Switched Domain, packet-switched domain) network can provide the user mobile number
According to business.User can using the mobile devices such as mobile phone, PAD by data service be connected to internet or
Proprietary network carrys out mobile office, browses webpage, check Email, play game on line, listen to online sound
Happy or viewing Online Video.
GPRS the and UMTS ps domain network architectures are shown in Fig. 1.User equipment is connected to BSC by wave point
(Base Station Controller, base station controller) (or RNC (Radio Network
Controller, radio network controller)), then it is being connected to SGSN (the Serving GPRS of core net
Support Node, service universal grouping wireless business supporting node), HLR (Home Location
Register, attaching position register), after judging that user can use the business that Home Network is provided, pass through
GGSN (Gateway GPRS Support Node, ggsn) equipment
Business network needed for user is connected to, then user can complete desired business.
In GPRS and UMTS ps domain networks, which data network user is connectable to and can obtain
Service to what rank is by the PDP (Packet Data Protocol, packet data protocol) of user
What subscription data was determined.By context ID, APN, (Access Point Name, connect PDP subscription data
Access point title), charging characteristic, route subscription data, QoS (Quality of Service, Service Quality
Amount) parameter such as subscription data composition.Context ID be identify PDP Serial No., scope from 1 to 50,
Do not allow to repeat.APN is APN, represents the title of current connection.Charging subscription data is represented such as
What carries out charging to user.Qos parameter is used to determine the available service class of user, such as accesses
Speed, packet loss etc..
Route subscription data is made up of pdp address type, address distribution options and corresponding address, is used for
Find the network that user accesses.Current 3GPP (3rd Generation Partnership Project,
Third generation partner program) in agreement, pdp address type includes two kinds of dynamically distributes and static allocation；
Address distribution options then include two types of PPP and IP, wherein IP types have be divided into IPv4, IPv6 and
Tri- kinds of IPv4/v6.In general, each SGSN should support dynamic and static allocation, but for
Address distribution options are then supported to be not quite similar.All of SGSN supports IPv4 types, and part is newer
SGSN can support that IPv6, the also SGSN of small part higher level can simultaneously support IPv4/v6.
Specify according to 3GPP agreements, each user can at most contract 50 PDP subscription data, this
A little subscription data are stored in HLR network elements.When user is in GPRS/UMTS ps domain network registries, HLR will
