Description

Internet protocol (IP) method for addressing that is used for BWA

Technical field

The present invention relates to IP (Internet protocol) address that a kind of transmission is applicable to BWA and set up the method for control messages, especially, relate to and a kind ofly transmit message to support the method for mobile IPv 4 and mobile IP v 6 with broadcasting or the multicast form that is used for setting up the address.In addition, method of the present invention is supported mobile IPv 4 and IPv6 mobile radio station, and it can use idle pulley its power consumption is reduced to minimum.

Background technology

Consider on network layer and the relevant communication protocol of wireless (radio) connecting system that to allow the appropriate data packet communications via the internet, Internet protocol (IP) is provided for essential addressing of packet and routing information.Here, each equipment that connects via the internet (for example, user terminal, mobile handset, wireless connections equipment, mobile subscriber station (MSS) or the like) need set up unique IP address, so that those equipment are correctly discerned and come with other implementation difference.

Developed the Internet protocol that is called IP version 4 (IPv4) and IP version 6 (IPv6).By adopting 32 bit address,, have been found that IPv4 has limitation, thereby each equipment that is connected with the internet needs it to have unique IP address because the growth of Internet traffic is popularized.Thereby, because the utilizability of 32 bit address will be very fast depleted, developed a kind of its improvement, that is, IPv6, it adopts 128 bit address.Among above-mentioned Internet protocol, an example that uses at the mobility aspect of supporting subscriber equipment (for example, user terminal, mobile handset, wireless connections equipment, mobile subscriber station (MSS) or the like) can be called mobility IPv4.

A lot of wireless networks and equipment still adopt the IPv4 addressing, and do not support the IPv6 addressing.Because following network and equipment are being developed and are only being supported IPv6, and before all networks and equipment transformed to the IPv6 addressing from the IPv4 addressing, one allowed network and equipment to support that side by side the solution in the transition period of IPv4 and IPv6 is desirable and essential.

Support the network of mobile IPv 4 to comprise local agent (HA), remote proxy (FA) and mobile radio station.

This mobile IPv 4 operation is as follows.When mobile node receives agent advertisement message, and determine whether that it is positioned at its local network or is positioned at external network (for example, far the network on ground).In addition, the Care-of Address that obtains from zone network far away (CoA) is registered on the local agent (HA).

Table 1 illustrates an example with respect to the agent advertisement message of mobile IPv 4 broadcasting.When the information relevant with remote proxy or local agent (FA/HA) by from mobile IP broadcast to mobile radio station the time, can use in this agent advertisement message shown in the following table 1.

[table 1]

In mobile IPv 4 statelessness address automatically in the configuration, as follows based on the method for setting up from the address of the help of base station.

At first, main frame (mobile radio station) uses FE80: :/64 (it is the local links prefix) and 48 interface identifier, so that derive interim local links address.In addition, for checking unique interim local chained address, neighbor request (solicitation) message is broadcast to this network, so that carry out the address detected of duplicating, if and interim local links address is not copy, router solicitation message is transmitted so.In addition, router advertisement message is received to derive global address.

Table 2 illustrates an example that is used for the neighbor request message of IPv6.

Above-described connection identifier (CID is unidirectional medium access control (MAC) layer address, and it is identified in being connected of equivalent peer entity in the MAC layer of base station and mobile radio station, and each connection comprises following.

The basis is established during being connected range finding, and refers to the connection that is used to transmit to the MAC administrative messag of delay-sensitive.The main connection refers to being used to of setting up and transmits postponing the connection of insensitive MAC administrative messag during finding range.Auxiliary connection refers to the connection that is used to transmit measured message (for example, DHCP, TFTP or the like).In addition, the transmission connection is the connection that is used to transmit user data.

Fig. 1 is the flow chart that is illustrated in the demonstration of the process that is used for the initialization mobile radio station in the BWA.With reference to figure 1, when the initial power of mobile radio station is unlocked, the searching downlink link channel, and the up link of acquisition and base station synchronization (UL) and down link (DL) are (S111).In addition, carry out range finding by means of the base station and pass a parameter (S112) to adjust up link, the basic management connection identifier (CID and first managing connection identification be by from base station assigns and reception, so as with base station negotiate basic function (S113).After carrying out authentication for mobile radio station (S114), this mobile radio station is to base station login (S115).The mobile radio station of managing by means of Internet protocol (IP) connects sign by base station assigns second management, and sets up IP connection (S116) via second managing connection identification.In addition, current date and time is set up (S117).The content file of mobile radio station is downloaded (S118) via second managing connection identification from tftp server, and sets up the connection (S119) that is used for previous service of preparing.

To explain now to use and connect the process of setting up according to the mobile IPv 4 of correlation technique or the IP of IPv6.

At first, it is as follows to use the connection of mobile IPv 4 to set up process.For the current IP that in most of internet environments, uses, suppose that an IP address can be used for the access point of recognition node (main frame or router) uniquely.In this case, for any node of the packet that is received in this transmission, it must be positioned in the network that comprises its IP address.Therefore, datagram can not send any node that is not positioned in the network that comprises its IP address to.

In order to allow node when keeping communication, to remove to change its access point, should use a kind of of two kinds of following methods.At first, node must change its IP address when its access point changes, and perhaps secondly, the address of the main frame that moves must be transmitted to whole internet.

These two kinds of methods have following problem.That is, in first method, when node location changed, the transport layer and the connection between the upper strata that remain on node were difficult.In addition, in the second approach, when the number of hypothesis mobile node when increasing, actual enforcement will be difficult.Therefore, need the mobility of the expansion technique of other types, and a kind ofly support that above-mentioned mobility method is mobile IP with support node in the internet.

Fig. 2 describes an example of supporting the network of mobile IP.As shown in Figure 2, support the network of mobile IP to consist essentially of local agent (HA) (21), remote proxy (FA) (22) and mobile node (23).

This HA and FA are used to transmit the node that datagram is given mobile node (23).When mobile node (23) and corresponding node (24) when communicating by letter,, need to support his process in case move to foreign network from local network.Mobile IP is via following process operation.

At first, mobile node (23) is carried out the process of finding an agency.Promptly, in order to notify its existence, mobile node has the agency or the mobility agent (it is a remote proxy) that adopt to use the agent advertisement message method, Internet Control Message Protocol (ICMP) the router discover method of its use when wishing when the Internet host to find router in existing internet step.Optionally, this mobile node (23) uses the agency to obtain message and goes to obtain agent advertisement message.The mobile node (23) that receives agent advertisement message determines whether that it is within the scope of its local network.

In addition, mobile node (23) determines that it is in foreign network, and the Care-of Address of mobile node (COA) is registered among the HA (21).That is, via above agent discovery process, if mobile node determines that it is in foreign network, then this mobile node and HA exchange register requirement and response message, with the COA (23) of registering mobile node.

For COA, can use two kinds of methods.First kind is remote proxy COA, and it is used as the COA of mobile node with FA (22), and second kind be the common COA that is provided with, and it distributes temporary ip address to give mobile node by DHCP (DHCP).The message of these registrations adopts User Datagram Protoco (UDP) (UDP) port numbering 434, and comprises the COA and the duration (lifetime) of mobile node.

To explain the method for operation of the correlation technique that disposes automatically according to statelessness address now based on IPv6.Main frame (mobile radio station) uses FE80: :/64 (it is the local links prefix) and 64 interface identifier, so that derive interim local links address.In addition, in order to check the local links address of unique interim derivation, neighbor request message is broadcast to this network and detects to carry out duplicate address.As the result who checks, if there is the address of duplicating, the neighbor advertisement response message is transmitted from the main frame that duplicates.

As the result who checks, if the address of not duplicating, main frame (mobile radio station) transmits router solicitation message.In addition, the router advertisement message of this reception is used to derive global address.

Fig. 3 is illustrated in the method for the router advertisement of the agent advertisement that is used to support mobile IPv 4 in the BWA and mobile IP v 6.

As shown in Figure 3, base station (32) receive from the mobile IPv 4 agent advertisement or the mobile IPv 6 routing advertisement of network (31) broadcasting, and this base station adopts the second management connection to be used for sending these to each mobile radio station with clean culture.Here, when mobile radio station to network registry the time, second managing connection identification is distributed in this base station during this process.

In the BWA of correlation technique, the second management connection is used to this mobile IPv 4 agent advertisement from Web broadcast, and perhaps the mobile IPv 6 routing advertisement individually sends all mobile radio stations (31) of current base station (32) to.But although agent advertisement and router advertisement are the message that is broadcast to all mobile radio stations usually, above-mentioned message is individually transmitted, and this causes wasting the problem of radio resource.

In BWA, the idle pulley of this mobile radio station is supported, so that power consumption is reduced to minimum.During idle pulley, when moving between the base station in identical paging zone, this mobile radio station does not need to carry out handoff procedure.Therefore, because this mobile radio station does not need to transmit the up-link information that is used for handoff procedure, can save the power consumption that it needs.

Common idle mode operations can be summarized as follows.

Paging zone refers to the whole zone of being handled by a plurality of base stations that are called paging group, and this base station that is included in the identical paging zone has identical paging cycle and paging offset value.

This portable terminal can ask the base station to change idle pulley into, and this base station can be by transmitting its paging zone ID and paging cycle and relative paging offset is changed into idle pulley with the corresponding mobile station.

During idle pulley, this base station might be gone to determine whether to keep or stop its idle pulley via paging, and this paging is transmitted from the base station with broadcasting format on agreed each paging cycle.When being in mobile radio station among the idle pulley and having the business that needs to transmit, this mobile radio station can at any time stop idle pulley.When being in base station among the idle pulley and having the business that needs to transmit, this base station can make this mobile radio station stop its idle pulley via paging.If be in mobile radio station among the idle pulley because such as moving to different paging zones, lose synchronously or the like, paging receiving not in the time limit that is provided with, this mobile radio station finishes its idle pulley.

Put it briefly, in the data that will not receive or transmit, the mobile radio station that enters idle pulley need not to carry out handoff procedure, can freely move in identical paging zone by the paging of receiving cycle correctly.

Be used for fixing/that mobile radio station is changed into the process of idle pulley is as follows.

1). fixing/mobile radio station sends idle-mode request message of serving BS to, so that change idle pulley into.

2). this serving BS sends paging packet ID, paging cycle and paging offset value to fixing/mobile radio station via an idle pulley response message, and will discharge with the link information of fixing/mobile radio station, radio resource of distributing to mobile radio station or the like.

Following table 7 illustrates the example of a message, and this fixes/and mobile radio station sends to the base station to ask idle pulley by using existing registration release request (DREG-REQ) message.

Below, be used for that (tie point) is sent to the process of mobile radio station from the base station with broadcasting or multicast form, by broadcasting or the multicast form network management connection identifier (CID that uses above identification, the message that IP is relevant is transmitted from network.

Fig. 4 illustrates the flow chart that is used for being transmitted to mobile radio station by the base station first embodiment of the relevant message of IP (it is transmitted from network) method.This embodiment can adopt the connection identifier (CID (CID) with first connection identifier (CID example structure.The base station uses this connection identifier (CID to send mobile radio station to the relevant message of IPv4 that broadcasting or multicast form will derive from network.

With reference to figure 4, first embodiment of the present invention can be explained as follows.In case power up mobile radio station searching downlink link channel, and the uplink/downlink synchronization of acquisition and base station (S411).In addition, by carrying out range finding with the base station, uplink transport parameter is adjusted, and the basic management connection identifier (CID is by base station assigns and derives from base station (S412) with main management CID.The negotiation (S413) of basic function is carried out in mobile radio station and base station, and carries out authentication (S414).When mobile radio station the time, be assigned from the auxiliary management CID (S415) of base station by the mobile radio station of IP management to base station login.

Mobile radio station uses auxiliary management to connect or transmission connects, and gives mobile agent (FA or HA) (S416) to transmit an agent solicitation message.The base station sends the agent solicitation message that comes from mobile radio station via auxiliary connection or transmission connection and gives mobility agent.The remote proxy (FA) or the local agent (HA) that receive agent solicitation message from mobile radio station transmit an agent advertisement message to base station (S418), and the base station sends corresponding mobile station (S419) to via assisting management or transmission to connect.

If mobile radio station is the part of remote proxy, for address (from agent advertisement message, obtaining) to local agent registration remote proxy, login request message connects via auxiliary management or the transmission connection is transmitted to base station (S420), and the base station sends login request message to local agent (S421).Receive the position (retraining the address of the remote proxy of mobile radio station by means of local address) of the local agent registration mobile radio station of register requirement, and send registration reply message to base station (S422).Connect or the transmission connection via auxiliary management, the registration reply message that the base station will derive from local agent sends mobile radio station (S423) to.

After finishing IP connection establishment step, mobile radio station sets Date and the time (S424).The content file of mobile radio station connects via auxiliary management is downloaded (S425) from tftp server, and the connection that is used for previous service of preparing is established (S426).The mobile radio station of finishing its network registry flow process changes normal operating state into.

The base station periodically receives agent advertisement message (S427) from FA, and sends these in the base station mobile IPv 4 mobile radio station (S428).Here, this transmission can be carried out via broadcasting or multicast form network management connection identifier (CID according to those that propose in the connection identifier (CID of first embodiment.That is, the base station can be used a predefined fixed value between mobile radio station and base station (for example, 0 * FEFE) as being used to transmit the connection identifier (CID of agent advertisement message.Use all mobile radio stations of mobile IPv 4 to receive the agent advertisement message that transmits via corresponding connection identifiers here.The mobile radio station that receives agent advertisement message determines whether that the FA address of its maintenance is effectively, and upgrades mobile IPv 4 address validity.

Carry out when switching when mobile radio station and different remote proxy network, mobile radio station is carried out the step (S416) of the registration process that is used for handover-target base station to (S423), connects so that set up IP.If mobile radio station is carried out switching in identical foreign network, the IP that is used for the establishment step of handover-target base station connects and can be omitted.In addition, do not consider to enter the inlet within another remote proxy network, after switching, the network management connection identifier (CID that mobile station via is identical as previously mentioned periodically receives agent advertisement message from the base station.

Fig. 5 illustrates the flow chart that is used for being transmitted to mobile radio station by the base station second embodiment of the relevant message of IP (it is transmitted from network) method.In this embodiment, can use connection identifier (CID with the form that in second embodiment, provides.The base station uses above-described connection identifier (CID to go to send mobile IPv 4 to mobile radio station with relevant internet message with broadcasting or multicast form.

With reference to figure 5, will explain second embodiment of the present invention.In case power up mobile radio station searching downlink link channel, and synchronous (S511) of the uplink/downlink of acquisition and base station.In addition, carry out with the base station range finding adjusting the uplink transmission parameter, and basic management connection identifier (CID and main managing connection identification are by from base station assigns (S512).The negotiation (S513) of basic function is carried out in mobile radio station and base station, and carries out the authentication (S514) for mobile radio station.When mobile radio station the time, receive by the mobile radio station of IP management and to be used for from second managing connection identification and the network management connection identifier (CID (S515) of network provider's identifier of base station assigns to base station login.

But, if by it being included in register requirement (REG-REQ) message, perhaps be included in mobile radio station key property request (SBC-REQ) message, mobile radio station sends network provider's identifier to base station, the base station comprises that the network management connection identifier (CID that is assigned to corresponding network provider's identifier enters within registration response (REG-RSP) message, shown in table 20, and it is distributed to mobile radio station.If by it being included in register requirement (REG-REQ) message, perhaps be included in mobile radio station key property request (SBC-REQ) message, mobile radio station does not send network provider's identifier to base station, the base station sends the map information of network provider's identifier and network management connection identifier (CID to mobile radio station, shown in table 21, and mobile radio station is that the network provider's of a part identifier receives administrative messag from Web broadcast via the network management connection identifier (CID with respect to it.

Mobile radio station uses second management to connect or transmission connects, and gives mobile agent (FA or HA) (S516) to transmit an agent solicitation message.The base station connects the agent solicitation message that will derive from mobile radio station via the second management connection or transmission and sends FA to.The FA that receives agent solicitation message from mobile radio station sends an agent advertisement message to base station (S518), and the base station sends corresponding mobile station (S519) to via second managing connection identification or transmission connection identifier (CID.

For with the address (obtaining) of local agent registration remote proxy via agent advertisement message, mobile station via second management connects or the transmission connection sends login request message to base station (S520), and the base station sends login request message to local agent (S521).Receive the position (by means of the address of home constraint remote proxy) of the local agent registration mobile radio station of register requirement, and send registration reply message to base station (S522).The base station connects the registration reply message that will derive from local agent via the second management connection or transmission and sends corresponding mobile station (S523) to.

The mobile radio station of finishing IP connection establishment step sets Date and the time (S524) then, and the content file of mobile radio station is connected from tftp server download (S525) via second management.The connection that is used for previous service of preparing is established (S526), and the mobile radio station of the network registry step of finishing changes normal operating state into.

The base station periodically receives agent advertisement message (S527) from FA, and sends it in the base station mobile IPv 4 mobile radio station (S528).Here, this transmission can be carried out via broadcasting or multicast form network management connection identifier (CID according to those that propose in the connection identifier (CID of second embodiment.

That is, the mobile IPv 4 mobile radio station receives the agent advertisement message that transmits via the network management connection identifier (CID that distributes during registration process, and the FA address that determines whether its maintenance is effectively, and upgrades mobile IPv 4 address validity.

Carry out when switching when mobile radio station and different remote proxy network, mobile radio station is carried out the step (S516) of the registration process that is used for handover-target base station to (S523), connects so that set up IP.If mobile radio station is carried out switching in identical FA network, the IP that is used for the establishment step of handover-target base station connects and can be omitted.In addition, be in mobile station via among the normal operating state and between transfer period, periodically receive agent advertisement message from the base station from the network management connection identifier (CID (according to the network provider) of base station assigns by step (S515).

But, if a base station is connected with various network providers, in order after switching, to receive from the agent advertisement message that is the Web broadcast of a part, then mobile radio station receives the map information of related network supplier's identifier and network management connection identifier (CID, and, can receive from the agent advertisement message that is the Web broadcast of a part based on these.In addition, if between the network provider, support roaming, even the mobile radio station experience switches to the base station that is connected to another supplier's network, this agent advertisement message can still receive via the network management connection identifier (CID of distributing to another network provider, therefore, allow mobile IPv 4 address validity to be updated.

Fig. 6 illustrates the flow chart that is used for being transmitted to mobile radio station by the base station the 3rd embodiment of the relevant message of IP (it is transmitted from network) method.In this embodiment, this connection identifier (CID can be the form that the connection identifier (CID by first embodiment provides.

With reference to figure 6, will explain second embodiment of the present invention.In case power up mobile radio station searching downlink link channel, and synchronous (S611) of the uplink/downlink of acquisition and base station.In addition, carry out with the base station range finding adjusting the uplink transmission parameter, and basic management connection identifier (CID and main managing connection identification are by from base station assigns (S612).The negotiation (S613) of basic function is carried out in mobile radio station and base station, and carries out the authentication (S614) for mobile radio station.When mobile radio station the time, receive by the mobile radio station of IP management and to be used for from second managing connection identification and the network management connection identifier (CID (S615) of network provider's identifier of base station assigns to base station login.

Mobile radio station uses FE80: :/64 (it is the local prefix of link) and 64 bit interface identifier, so that derive interim link local address (link-local address).In addition, for some address copies of the interim link local address of checking derivation, neighbor request message uses auxiliary management to connect or transmission connects and is transmitted to base station (S616).The base station connects the neighbor request message that will derive from mobile radio station via auxiliary management connection or transmission and sends router (S617) to.

This router sends the neighbor request message that receives in subnet all base stations (S618), and those base stations send neighbor request message to IPv6 mobile radio station (S619) via the network management connection identifier (CID with the form that is provided by first embodiment of connection identifier (CID.The mobile radio station inspection that receives neighbor request message from the base station looks at whether to exist some copies of other address, and is when having copy, transmits neighbor advertisement message.

If do not receive neighbor advertisement message by the mobile radio station that transmits neighbor request message during certain time cycle, it is unique that the link local address of derivation is determined.If it is unique that the link local address is determined, router solicitation message connects via auxiliary management or transmission connects and is transmitted to the base station so that find router (S620), and the router solicitation message that the base station will derive from mobile radio station sends router (S621) to.

The router that receives this router solicitation message sends router advertisement message to base station (S622), and use auxiliary management in base station connects or the transmission connection goes to send router advertisement message to corresponding mobile station (S623).The router advertisement message of this reception is used to derive global address and connects foundation to carry out IP.

The mobile radio station of finishing IP connection establishment step is provided with current data and time (S624), and the content file of mobile radio station is connected from tftp server download (S625) via auxiliary management.The connection that is used for previous service of preparing is established (S626), and the mobile radio station of finishing the network registry step changes normal operating state into.

This base station is periodically from router receiving router advertisement information (S627), and it can be transmitted to IPv6 mobile radio station (S628) in the base station via having network management connection identifier (CID according to the broadcasting of first embodiment of connection identifier (CID or multicast form.The mobile radio station that receives this router advertisement message determines whether its global address is effectively, and upgrades the tabulation of effective router.

In above-described step (S627), being used for the connection identifier (CID that router advertisement message sends mobile radio station to by the base station can be before by the fixed value (for example, 0 * FEFE) of mobile radio station and base station definition.Here, all IPv6 mobile radio stations receive the router advertisement message that transmits via corresponding connection identifiers.When the mobile radio station execution switched to another router (subnet) network, mobile radio station connected to set up IP by the step of carrying out among the network registration process of handover-target base station (S617)～(S620).

If mobile radio station is carried out switching in identical router (subnet) network, the IP connection of the step (S617)～(S620) of use among the network registration process of handover-target base station is set up process and can be omitted.In addition, do not consider to enter the inlet of another remote proxy network, after switching, the network management connection identifier (CID that mobile station via is identical as previously mentioned periodically receives agent advertisement message from the base station.

With reference to figure 9, one embodiment of the present of invention will be explained as follows.The base station periodically receives this router advertisement message from router, and sends it in the base station IPv6 mobile radio station (S911) via having as the network management connection identifier (CID of the multicast form that proposed by the present invention.Promptly, via the network management connection identifier (CID that in first and second embodiment of the present invention, defines, each IPv6 mobile radio station receives this router advertisement message, and the router prefix information that determines whether its maintenance is effectively, and upgrades the validity of IPv6 address.

In order to change idle pulley into, mobile radio station transmits an idle-mode request message to base station (S912).The base station sends an idle pulley response message to mobile radio station, changes idle pulley (S913) into to allow it.By periodically receive the paging advertisement information of broadcasting format from the base station, mobile radio station receives the order that whether has produced the downlink traffic that will send, and perhaps whether it is with executing location renewal process (S914).If remove to keep its idle pulley via the order of page advertisement information, this idle pulley is held till one page advertisement information is transmitted down, therefore power consumption is reduced to minimum.

After mobile radio station is by the validity that receives a router advertisement message renewal IPv6 address, when the next router advertisement message delivery time arrives, obtain downlink synchronization with the base station, and descending chain circuit frame is continuously received, up to router advertisement message by via as the specific connection identifier (CID of the multicast form that proposes by the present invention receive till (S915).(in order periodically to transmit router advertisement message, this router uses randomly in predefined minimum and the transmit stage selected between the maximum stage and goes to send router advertisement message to network with broadcasting format.Therefore, mobile radio station receives a router advertisement message with idle pulley, and can keep its idle pulley at least during the minimum transfer stage).The mobile radio station that receives this router advertisement message determines whether that its router prefix information that is keeping is effectively, upgrades the validity of IPv6 address, and keeps idle mode state once more.

This mobile radio station periodically receives broadcasting format beep-page message (S916), and periodically via as the specific connection identifier (CID of the multicast form that proposes by the present invention receive this router advertisement message (S917).

In the operation of the present invention, the process that is used for via the connection identifier (CID that proposes in the present invention agent advertisement message, neighbor request message and router advertisement message being sent to from the base station mobile radio station has been described.But, this only is exemplary, also can transmit via the connection identifier (CID that proposes by the present invention as the measured administrative messag of other types (it need be transmitted by broadcasting or the multicast form with the MAC administrative messag that is different from BWA).

Consider the influence of BWA of the present invention, define a connection identifier (CID, so that those message that are used for address foundation from the BWA transmission from this Web broadcast with broadcasting or multicast form, can send mobile radio station to broadcasting or multicast form by using above-described connection identifier (CID with message, thereby save radio resource from Web broadcast.

The present invention with by different IEEE working groups, relevant such as the research and development that IEEE 802.16 implements, therefore, notion that relates to therein and instruction are applicable to feature of the present invention.

For example, IEEE802.16e uses DHCP (dynamic main machine structure agreement) and mobile IP, so that mobile subscriber station (MSS) is given in the distributing IP address.But when using IPv6, the IP address is or disposes (IETF RFC2462) automatically or by the state address automatic configuration protocol is arranged by IPv6 statelessness address, such as DHCPv6 (IETF RFC3315) configuration.

The invention provides a kind of modification to allow by state or statelessness process distributing IP v6 addressing are arranged.This is by increasing SS (mobile subscriber station) IPv6 address and decomposing IPv4 and the realization of IPv6 address.

For MSS, if using mobile IP, this MSS can use mobile IP to connect in auxiliary management and make its address safety.Otherwise for fixing subscriber station with for the MSS that uses IPv4 and do not use mobile IP, subscriber station (SS) will call DHCP mechanism [IETFRFC2131], so that obtain an IP address and set up any other the parameter that IP is connected needs.This dhcp response is with the title of include file, and this document comprises more configuration parameter.For fixing SS with for the MSS that uses IPv6, this SS will be based on the value of the type lengths values (tlv) byte group in registration response (REG_RSP) message, perhaps call DHCPv6[IETF RFC3315], perhaps will call IPv6 statelessness address self structure [IETFRFC2462].Can connect in the auxiliary management of SS and carry out the IP establishment of connection.

Following table 22 and 23 is illustrated in the example that is used for the TLV byte group that the method for distributing IP address uses according to the present invention.
