Description
Technical field
The present invention relates to field of wireless, relate in particular to the method for selecting mobile management mode in a kind of wireless network.
Background technology
Mobile IP (Mobile IP) is a kind of mobility management protocol that is extensively received, it can keep portable terminal (MN, Mobile Node) between heterogeneous networks when mobile IP connect and do not interrupt.In mobile IP, portable terminal keeps its ownership place IP address (HoA, Home of Address) constant, when the access point of portable terminal changes, portable terminal is by Binding Update (Binding Update, be applicable to MIPv6) or login request message (RRQ, Register Request, be applicable to MIPv4) this change notification is positioned at the home agent (HA of its home network (Home Network), Home Agent), can be properly routed to new access point so that send to the data of this portable terminal.
Mobile IP technology requires portable terminal to support mobile IP protocol.In the realization of reality, the portable terminal of supporting mobile IP is arranged seldom.Therefore, the technology of a kind of proxy-mobile IP (PMIP, Proxy Mobile IP) is developed.Proxy-mobile IP is meant and has an agent node (Proxymobile IP Agent) in access network, when portable terminal is mobile between diverse access point, this agent node is responsible for replacing portable terminal to send mobile IP binding update messages or login request message to its home agent, to notify the reposition of its this portable terminal of home agent.
When portable terminal is mobile between networks of different type, as moving to WiFi (Wireless Fidelity) network from UMTS (universal mobile telecommunications system) network, often need to switch to another network adapter from a network adapter, such as, switch to the WiFi network interface card from PCMCIA (the PC RAM (random access memory) card international federation) card of supporting UMTS, at this moment, supporting business not interrupt, the heterogeneous networks adapter must use same IP address (being HoA) before and after switching.In the realization of present wireless terminal, fail the IP layer is separated well with the MAC layer, therefore, present most of portable terminals are not supported this function.Such portable terminal can't use proxy-mobile IP to keep the continuous of business when doing the switching of across a network type, and must use mobile IP to keep business continuous.
In addition, the support to proxy-mobile IP is a kind of ability of access network.A lot of existing access networks do not possess the ability of supporting proxy-mobile IP; And proxy mobile IPv 6 has been introduced new variable, and this requires home agent also must support this variable could support proxy-mobile IP.
When a portable terminal started in a new access network or switch to a new access network, selecting proxy-mobile IP still was that standard moves IP and becomes a new problem.This need take all factors into consideration the ability of portable terminal, the ability of access network and the ability of home agent.The MIP (as MIPv4 or MIPv6) that portable terminal may be supported standard also may not support mobile IP.When portable terminal is not supported mobile IP, then require access network to support proxy-mobile IP, otherwise can't guarantee the business continuance of portable terminal.With IPv6 is example, and possible combination is as shown in table 1:
Table 1:
| The mobility management protocol that MN supports (for example: the UE among Fig. 1) | The mobility management protocol of access network (for example: ePDG among Fig. 1) | The mobility management protocol of home agent (for example: PDN GW among Fig. 1) | Decision-making |
| MIPv6，PMIPv6 | PMIPv6 | MIPv6，PMIPv6 | Need do selection |
| MIPv6，PMIPv6 | MIPv6 | MIPv6 | |
| MIPv6，PMIPv6 | PMIPv6 | PMIPv6 | PMIPv6 |
| MIPv6 | PMIPv6 | MIPv6，PMIPv6 | Need do selection |
| MIPv6 | PMIPv6 | PMIPv6 | Failure |

| PMIPv6 | MIPv6 | Failure | |
| PMIPv6 | PMIPv6 | MIPv6，PMIPv6 | PMIPv6 |
| PMIPv6 | PMIPv6 | PMIPv6 | PMIPv6 |
As can be seen from Table 1, in most cases, selection result determines, only just has the selection problem when portable terminal, access network and home agent are all supported multiple different mobility management protocol.But,, also still have problem how to know the mobility management protocol that other entities are supported between network entity even if under the situation that result as shown in table 1 determines.Such as, how does portable terminal know that access network is to support PMIPv6, thereby selects PMIPv6 as current mobility management protocol? how about does access network know that the home agent of portable terminal supports PMIPv6?
Defined a kind of system of selection that does not need the mutual mobility management protocol of ability of implicit expression in WiMax (micro-wave access global inter communication) standard.In WiMax, stipulate, when portable terminal (Mobile Station) is supported MIPv4, preferentially select MIPv4; Otherwise adopt proxy-mobile IP v4.After the access authentication of portable terminal finishes, IAD sends advertising of route message (RouterAdvertisement) to portable terminal, the address that in this message, comprises IAD, this address be used as portable terminal the concern address (CoA, Care-of-address).If IAD is received the login request message (RRQ) that portable terminal sends, then IAD determines that this portable terminal is to support MIPv4, so select the mobility management protocol of MIPv4 agreement as this portable terminal; If IAD is received the dhcp discover message that portable terminal sends, then this IAD thinks that this portable terminal do not support MIPv4, so select the mobility management protocol of PMIPv4 as this portable terminal.
IPv4 is only supported in the system of selection of the mobility management protocol of this implicit expression among the WiMax, and the situation (Client based MIP) in the time of can only being used in the mobile IP that is preferably based on terminal, when needs are supported IPv6, when maybe needing to support preferred proxy-mobile IP, need a kind of new method.
In sum, currently need a kind of explicit method that needs the mutual selection mobile management mode of ability badly.
