In addition, Fig. 5 is with the difference of Fig. 6: a home agent 50 is connected with link 1 in Fig. 5, and is relative therewith, and two home agent 50a are connected with link 1 with 50b in Fig. 6.
Embodiments of the invention are under portable terminal 10 and state that link 1 is connected, the triggering that has given by user interface is replied, with the link identification that connects is home link, and the home agent 50 that handle is connected with link 1 is set at the home agent of accommodating oneself.And then portable terminal 10 is stored the IP address that the network prefixs according to home agent 50 issues have generated as home address, on one side and carry out mobile IP protocol with reference to the information of having set later on one side and handle.
In addition, having obtained under the situation of home agent information, judge whether this message reflection in protocol processes by the user according to DHCP etc.Thus, portable terminal 10 can belong to the home agent of the communication environment of realizing that user or application program are wished.
At first, be that the method that opportunity is obtained home agent information describes to the triggering of having sent with the user.
In mobile communication system shown in Figure 5, the user who uses portable terminal 10 presses the button that portable terminal 10 is possessed when carrying out the setting relevant with the mobile IP of portable terminal 10, make switch transition become the ON state, sends indication to portable terminal 10.At this moment, the router-list of the information of the router that connects has been put down in writing in portable terminal 10 reference on one side, Yi Bian carry out address information setting.
Fig. 8 is the structural representation of router-list.
In Fig. 8, router-list 150 has been put down in writing link layer address 151, IP address 152, prefix 153, home agent identifier 154 at least for each router.With portable terminal 10 that mobile communication system shown in Figure 5 is connected in, registered the inlet 161 that is equivalent to router 60,162 two inlets of inlet that are equivalent to home agent 50.Portable terminal 10 in these inlets, select with home agent identifier 154 be that the suitable inlet of the inlet 162 of ON is as home agent 50.
Here, portable terminal 10 is stored the IP address ip 2 of the home agent 50 selected as the address of home agent 50, prefix Prefix_2 is stored as the prefix of home link, the IP address that has generated according to prefix Prefix_2 is stored as home address.After, portable terminal 10 is when carrying out the mobile IP protocol processing, with reference to the IP address and the home address of the home agent of having stored before 50.
In addition, in mobile communication system shown in Figure 6, portable terminal 10 has router-list shown in Figure 9 150.That is, registered with the corresponding inlet 161 of router 60, with the corresponding inlet 162 of home agent 50a, with the corresponding inlet 163 of home agent 50b.At this moment, because a plurality of home agents 50 are connected with link 1, so portable terminal 10 can determine it is these whole routers of selection, still selects a plurality of routers or selects a router.
Selecting under the situation of all routers as home agent, it is the inlet 162 and 163 of ON that portable terminal 10 is selected home agent identifier 154.That is, select home agent 50a and 50b, and act on behalf of IP address, the prefix of home link, the home address of 50a and 50b according to the step store home of explanation before as the home agent of accommodating oneself.
Under the situation of selecting a plurality of routers, can also put down in writing home agent priority 1 55 by making router-list 150, thereby can select more suitable home agent 50.That is, selecting home agent priority is the above home agent of certain value.For example, when to select home agent priority be home agent ' 1 ' or more, select and enter the mouth 162 and 163 corresponding home agent 50a and 50b were as home agent.In addition, also can select a plurality of home agents 50 randomly regardless of home agent priority 1 55.
Under the situation of selecting a home agent, adopt home agent priority 1 55 equally.For example, the priority when making home agent priority 1 55 expression portable terminals 10 select to accommodate the home agent 50 of destination waits according to load condition, device performance and the gerentocratic wish of home agent and to set.And the home agent of oneself is accommodated in the inlet 162 corresponding home agent 50a conducts that selection and home agent priority are the highest.In addition, also can select a quilt to accommodate home agent 50 randomly regardless of home agent priority.
In addition, portable terminal 10 also can obtain route-map from router 60 and the home agent 50 that is connected with link 1 after the triggering that receives from the user.Promptly, portable terminal 10 sends the router request message (Router Solicitation Message) that is used to obtain route-map to link 1, reply as it, receive the router advertisement message (Router Advertisement Message) 200 that sends by router 60 that is connected with link 1 and home agent 50.Then, portable terminal 10 upgrades router-list 150, and according to handling with the selection that above-mentioned identical step is carried out home agent.Then, carry out the setting of home link prefix, home address.In addition, portable terminal 10 also can not carry out the renewal of router-list 150, and each message that receives is carried out above-mentioned processing.
Here, Figure 10 represents the basic structure of router advertisement message 200.
Be documented in route-map in the router advertisement message 200 be included at least before the information of record among Fig. 8, router-list 150 shown in Figure 9 of explanation.Promptly, the H identifier 211 of ICMPv6 router advertisement 210 is equivalent to home agent identifier 154, the prefix field 221 of prefix information option 220 is equivalent to prefix 153 and IP address 152, and the home agent priority field 231 of home agent information option 230 is equivalent to home agent priority 1 55.Though not expression among the figure, the option by additional record link layer address can obtain link layer address 151.
In addition, under the situation that portable terminal 10 moves as mobile router, in the router advertisement message 200 that receives, only the home agent that will be provided with identifier 232 is as alternative, and described identifier 232 expression home agents are home agents of mobile router correspondence.Thus, owing to can not select the home agent not corresponding with mobile router, so need not search for home agent once more.And, because the home agent selected is corresponding with mobile router, so in the data packet transceive of the portable terminal that is connected with mobile network under mobile router is controlled, can prevent the loss of packet in advance.
And this moment, in order to distinguish home agent corresponding and non-corresponding home agent, also the corresponding hurdle 156 of MR (mobile router) can be set in router-list 150 with mobile router.Thus, even mobile router handovers the connection to and the non-corresponding home agent of mobile router as under the situation that simply portable terminal moves afterwards, just can lower the processing load of the home agent corresponding with mobile router.
And, when the home agent corresponding with mobile router accommodated a plurality of mobile router, reducing the resource discharged and be used for effectively other mobile router transfer data packets etc. is handled owing to accommodating quantity.Thus, home agent is compared with simple portable terminal, can more stably handle to have the message volume that increases tendency.
In addition, in the above-described embodiment, to pressing the button that portable terminal 10 is possessed, make switch be in the ON state and establishing method that the triggering that takes place is replied is illustrated, but can also pressed button during, switch be in the ON state during in carry out and set.Especially, be object only with the router advertisement message 200 that receives in during above-mentioned, carry out the selection of home agent and the situation of the information setting relevant with home agent, with triggering is replied situation about setting and compares, can not need to manage the timer of stand-by period, the described stand-by period is used to finish the reception of router advertisement message 200.
Then, use accompanying drawing that the structure and the action of portable terminal 10 of the present invention are described.
Fig. 1 and Fig. 2 are the pie graphs of portable terminal 10 of the present invention.
In Fig. 1, L1/2 handling part 11 sends or received frame from link 1, the processing of execution level 1 and layer 2.L3 handling part 12 carries out layer 3, for example processing of Internet Protocol (IP), and upper layer handling part L3 carries out the control of application program or to session management etc. layer 3 upper.In addition, L1/2 handling part 11 is equivalent to sending part of the present invention and acceptance division.
In addition, the user judges that acquisition unit 17 obtains the triggering regularly of expression information setting from user interface part 18, the control of acquisition unit 17 is judged according to this user by information setting portion 16, information storage part 15 is used to set the control of the related information of effective home agent.In addition, user interface part 18 is equivalent to input part of the present invention and display part.
In addition, mobile IP handling part 14 uses the home agent information of having stored in information storage part 15, and the mobile IP protocol of the operative norm of cooperating with the L3 handling part is handled.
Portable terminal 10 shown in Figure 2 also is provided with the L1/2 handling part 19 different with L1/2 handling part 11, moves as mobile router.In addition, portable terminal 10 also can be the structure that a plurality of L1/2 handling parts 11,19 are set.
Use Fig. 3 to above-mentioned such portable terminal that constitutes 10, effectively the setting of home agent is handled and is described in detail.In addition, even below Shuo Ming action also is identical in any portable terminal illustrated in figures 1 and 2.
At first, set button etc. when the user presses, the user judges that acquisition unit 17 receives expression when setting regularly triggering (S101) from user interface part 18, is notified to information setting portion 16 with it thus.
Then, information setting portion 16 usefulness ' 0 ' are carried out initialization (S102) to the variable Count_HA of management home agent quantity in the processing afterwards.Then, information setting portion 16 is with reference to the router-list of L3 handling part 12 management, the setting of information such as the following selection of carrying out home agent 50 like that and home agent address.At first, 16 pairs of registered each inlets (S103) in router-list 150 of information setting portion, confirm whether home agent identifier (H identifier) 154 is ON (S104), under the situation that is not ON (for OFF), return the processing that step S103 begins next inlet, till not having untreated inlet.
In step S104, when home agent sign (H sign) 154 was ON, whether differentiation should enter the mouth as alternative (S105).For example, judge whether to have high priority (with reference to the home agent priority 1 55 of router-list 150) for the home agent of selecting before 50.Under situation not, turn back to step S103, the processing of the next inlet of beginning as alternative.
On the other hand, under situation, in information storage part 15, set the IP address 152 of inlet as the IP address of home agent, and information storage part 15 is logged into information in the storage area of management (S106) as alternative.And then the IP address of the portable terminal 10 that has generated the prefix 153 of inlet with by prefix 153 is set in the information storage part 15 as home link prefix and home address respectively, and information storage part 15 is logged into information in the storage area of management (S107).
Here, Fig. 7 represents the storage area that information storage part 15 is managed.
Among Fig. 7, home address is stored in the home address storage area 101, and the IP address of home agent is stored in the home agent address storage area 102, and the prefix of home link is stored in the home link prefix storage area territory 103.
Then, information setting portion 16 increases the variable Count_HA (S108) that registered home agent quantity is managed, and differentiates the upper limit (S109) that whether has reached the home agent quantity of selecting.Do not reaching in limited time, turn back to the processing of the next inlet of step 103 beginning, but under the situation that does not have next inlet, display setting is being finished dealing with (S120) on user interface part 18, and transfers to the wait state of step S101.On the other hand, on having reached,, transfer to step S120 in limited time.As the higher limit of this home agent quantity, establish the value of a non-attribution agency's sum.In addition, also can dispense the step S120 that display setting is finished.
In addition, can registered home agent 50 in router-list 150 not carried out information setting, but send the router request message that is used to ask route-map to the link 1 that connects, carry out information setting according to the real time information of the router advertisement message of replying from it.Below, use 4 pairs of processing in this case of accompanying drawing to describe.
At first, information setting portion 16 requires the transmission of router request message to L3 handling part 12 when judging that from the user acquisition unit 17 receives the triggering of representing to set regularly (S101).Then, L3 handling part 12 sends router request message (S111) by the L1/2 handling part 11 that is connected with link 1.In addition, also can send router request message to the link of all connections by all L1/2 handling parts.
Then, information setting portion 16 usefulness ' 0 ' are carried out initialization (S102) to the variable Count_HA of management home agent quantity in the processing afterwards.
Then, L3 handling part 12 is notified (S112) to information setting portion 16 when upgrading router-list 150 when receiving router advertisement message 200.
Then, 16 pairs of router advertisement message that receive of information setting portion 200 are carried out the processing of step S104～S108 shown in Figure 3.Then, whether the quantity of the registered home agent of information setting portion 16 differentiations has reached the upper limit (S109) of the home agent quantity of selecting.Not reaching in limited time, turn back to step S112 and detect the reception of router advertisement message next time.When the reception that does not have next time, display setting is finished dealing with (S120) on user interface part 18, and transfers to the wait state of step S101.On the other hand, on having reached, transfer to step S120 in limited time.As the higher limit of this home agent quantity, establish the value of a non-attribution agency's sum.
In addition, information setting portion 16 is when receiving router advertisement message 200, because L3 handling part 12 upgrades router-lists 150, and therefore can be to the processing of the inlet execution in step S104～S108 of all router-lists 150.
And, in step S105, also can judge which home agent is acquisition unit select to user interface part 18 prompting users, and established home agent is selected by information setting portion 1 by the user.Thus, can select home agent, therefore can under the condition that is fit to data content, communicate according to user's wish.
