Background technology
In following wireless network, it is main flow trend that the whole network IP (Internet Protocol, Internet protocol) changes.First 3GPP (3rd Generation Partnership Project of formal issue, the 3G (Third Generation) Moblie standardization group) the design version R99 of system is the existing GSM circuit switching system of back compatible, but because purchase, the cost of maintenance circuitry switching system special hardware is very high, the bandwidth loss that is used for transmitting user data is also very big, so the 3GPP system begins to turn to gradually a kind of whole IP-based core network.This means being growing more intense owing to market competition, existing circuit switching system will be eliminated, the substitute is opening, favorable expandability, purchase the IP-based hardware system also cheaper with maintenance cost, service newly developed in the market in addition and application also mostly are based on IP's.For above-mentioned reasons, the the 4th and the 5th version of 3GPP standard also more and more given prominence to the importance of IP framework and introduced IMS (IPMultimedia Subsystem, IP Multimedia System) this notion, the one, wishing provides traditional circuit switched service (as voice service) by the form of IP to the user, and the 2nd, wish to realize providing all multimedia services to the user by this subsystem.IMS is an expansion to packet switched core network, be intended to be independent of packet switched core network later on from the 6th version of 3GPP, it uses SIP (SessionInitiation Protocol, Session initiation Protocol) foundation, maintenance and terminated speech and multimedia process.
The PoC that uses in the system of the whole network IP (Push to Talk over Cellular, Push to talk over Cellular) business will obtain using very widely in following 3G uses.PoC service is that a kind of user of permission sets up the half-duplex voice business of communicating by letter immediately with other one or more users by specific keys.It is the application of VoIP business in the mobile network, and the function of " one to one " and " one-to-many " group call can be provided neatly.At present PoC service is based on the SIP application and development and forms, and has communication immediately, group communication, half-duplex, directly answers, VOIP characteristics such as (Voice Over IP).
At IMS (IP Multimedia Subsystem, IP Multimedia System) and in the system of other the whole networks IP, PoC (Push to Talk over Cellular, Push to talk over Cellular) professional and other SIP (SessionInitiation Protocol, Session initiation Protocol) applied business need be used SIP URI (Uniform ResourceIdentifiers, the unified resource sign), SIP user application information such as EMAIL, these user profile are corresponding with user's TEL URI (Telephone Uniform Resource Identifiers, identification of contacts).Terminal is when opening the SIP applied business, and the corresponding relation of SIP user application information and user's TEL URI (telephone number sign) is stored on the SIP application information service device.
