Background technology
CDMA and WiMAX network support simple IP (Simple IP is called for short SIP) and two kinds of Packet Service patterns of mobile IP (Mobile IP is called for short MIP).SIP is the basic service pattern of cdma network Packet Service, is similar to dial business.When the user uses data, services, adopt the mode and the PDSN of similar dialing to set up PPP (Point to Point Protocol, peer-peer protocol) point-to-point connects, and PDSN (Packet Data Serving Node, group data service node) is responsible for data transmit-receive.When connecting, the user obtains a dynamic IP addressing, each IP address possibility difference that obtains that connects by network allocation.When the user stops data, services, disconnect connection.In the network that if this user is in same PDSN to be covered always, can keep IP address allocated constant.But when the user moves out the network that above-mentioned PDSN covers, network will be cut off the current connection of user, if the user need continue data, services, and dial-up connection again, network will be distributed to new IP address of user.Since the user is each connect the IP address that obtains may be different, SIP only supports the business that the user initiatively initiates, and the business of can not the network enabled side initiatively initiating, and the continuation of SIP business can not guarantee that the user moves the time.
MIP is the another kind of mobile Packet Service pattern of CDMA 2000 network supports.When the user adopts MIP to insert, can use static ip address or dynamic IP addressing.The user can arbitrarily move in CDMA 2000 packet field networks, keeps same IP address.Therefore, all business that MIP can not only provide SIP to provide can also provide the business of network push (Push).Use the MIP pattern need possess several conditions: to need the terminal of supporting MIP; Network need increase new equipment home agent server HA; PDSN need support external agent FA function in the network.Compare with SIP, increased HA (HomeAgent in the MIP network, home agent) equipment, HA has public ip address, the mobile subscriber registers to HA by PDSN, and, between PDSN and HA, set up the service tunnel of unidirectional (from HA to PDSN) afterwards, then with regard to addressable extenal grouped network from HA acquisition IP address.The IP address that the user obtains among the MIP is distributed by HA, and no matter the user is positioned at ownership place or roaming place, and the IP address that the user obtains remains unchanged in moving process.Upstream data at first sends to PDSN from terminal under the MIP pattern, PDSN arrives target device with the direct routing forwarding of packet again, the down direction packet by target device at first routing forwarding send to PDSN by HA through the IP-in-IP tunnel to HA, PDSN is transmitted to terminal again.As long as IP address is constant, user's service just can not interrupted.
In addition, IETF has proposed the proxy-mobile IP grouping connection mode of (Proxy MIP is called for short PMIP), has all adopted this business model to keep the continuity of Packet Service in WiMAX, CDMA, the LTE network respectively.PMIP can reach identical purpose with MIP, and the IP address that promptly keeps the user to obtain remains unchanged in moving process, thereby keeps the continuity of mobile service.PMIP only needs terminal to support that SIP gets final product, and replaces terminal to finish the MIP related procedure by the network equipment.PMIP compares with MIP, and its advantage is the needs that reduced terminal, and has reduced the space interface signaling load.More existing at present operator's plans upgrade its mobile network to support PMIP.
At present, the Packet Service pattern that the network support of different mobile operator is different, if any cdma network support MIP, the CDMA that has only supports SIP, the cdma network that also has is supported MIP and SIP simultaneously.Different mobile network's abilities, and operator proposed different demands for the consideration of its operation strategy to portable terminal, some Carrier Requirements terminal must be supported MIP, some Carrier Requirements terminal is only used SIP.Portable terminal divides according to the business model of its support, has three kinds: support SIP for a kind of; Support MIP, a kind of MIP and SIP of supporting simultaneously for a kind of.For the portable terminal of supporting MIP and SIP simultaneously, network capabilities and operation strategy according to operator have three kinds of configurations: only use SIP at present; Only use MIP; MIP is preferential, promptly uses MIP earlier, if the unsuccessful SIP that re-uses.At the terminal of certain carrier customization, business model and the configuration that portable terminal need be supported all can be informed by operator.
For home network, home-operator has been determined business model and the configuration that portable terminal need be supported.But when terminal roaming arrives the mobile network of other operators,, promptly whether support SIP, MIP and PMIP, just can't judge and use which kind of business model initiation packet to connect because terminal is not known its current place mobile network's business model support situation.For example: MIP is only used in configuration on Sprint user's the terminal, when this user roams into the network of not supporting MIP, because terminal can't fall back to SIP, just can't normally be linked into this mobile network; SIP is only used in configuration on the user's of China Telecom the terminal, when this user roams into the network of supporting MIP, because terminal is only used SIP, just can't attempt the MIP initiation packet and connect, and enjoys the professional advantage that MIP brings.When certain network support PMIP, but PMIP has certain advantage than MIP, and promptly all terminals can all be used SIP, comprise the terminal of supporting MIP and SIP simultaneously, have guaranteed the consistency of operation flow, and has saved the space interface signaling load; But because terminal is not known network capabilities, be configured to the still preferred MIP pattern of the preferential terminal of MIP, cause PMIP not bring into play its due advantage.
