At first, on the name server 150 of general grouped wireless communication network, dispose the user ID of travelling carriage 1 and 2 and the corresponding relation of IP address.Described IP address is that travelling carriage 1 and 2 is successfully initiated the pdp address that obtains after the PDP activation process.
When network node visit travelling carriage 1 or 2, will send the user ID of the travelling carriage of desire visit to name server 150; Name server 150 is corresponding IP address according to aforementioned corresponding relation with described user identity resolution, and this IP address is sent to described network node; Then, described network node just can communicate according to IP address that receives and described travelling carriage.
For the ease of the understanding of the present invention, describe the present invention in detail below in conjunction with embodiment.In following embodiment, the domain name of supposing packet data switched network is abcpdn.net.The mutual visit between travelling carriage, other nodes in the network (as main frame etc.) can conduct interviews to travelling carriage.
Embodiment one
Please consult Fig. 2 once more, when the networking of packet data switched network 140 fairly simple, be that host number in the territory is not when being very big, single name server 150 can be set, at the host domain name of 150 li configuration travelling carriages 1 of name server and 2 and the IP address corresponding relation of travelling carriage in packet data switched network 140.
If packet data switched network 140 is company's nets, can adopt then that self-defining user name disposes the host domain name of travelling carriage 1 and 2 in the company on name server.Use travelling carriage 1, employee Y to use travelling carriage 2 to be example with employee X, then travelling carriage 1 can use x.abcpdn.net, and travelling carriage 2 can use y.abcpdn.net.
When employee X visits the travelling carriage 2 of employee Y with travelling carriage 1, travelling carriage 1 is initiated the PDP activation process by land radio access web/base station sub-system 111 and Serving GPRS Support Node 121, obtains the IP address of name server 150 from Gateway GPRS Support Node 131.Travelling carriage 1 sends the inquiry of the domain name request to name server 150, and request name server 150 resolves to corresponding IP address with y.abcpdn.net; Name server 150 is found the IP address of y.abcpdn.net and is sent to travelling carriage 1 in the domain name of this machine and IP address mapping table, and travelling carriage 1 just can send the IP messages to travelling carriage 2 by this IP address like this.
If packet data switched network 140 is networks of mobile service provider, then can adopt the domain name of international mobile subscriber number as travelling carriage.The international mobile subscriber number of supposing travelling carriage 1 is 8613812345678, and node in this packet data switched network 140 such as travelling carriage 2 just can use domain name ms8613812345678.abcpdn.net to visit travelling carriage 1 so.
When travelling carriage 2 was initiated the PDP activation process, Gateway GPRS Support Node 132 can be issued travelling carriage 2 with the IP address information of name server 150.When travelling carriage 2 visit ms8613812345678.abcpdn.net, at first travelling carriage 2 can send the inquiry of the domain name request to name server 150; Name server 150 resolves to the IP address of travelling carriage 1 with ms8613812345678.abcpdn.net, and sends to travelling carriage 2, and travelling carriage 2 just can send the IP message to travelling carriage 1 by this IP address like this.Whole process is transparent to the mobile subscriber.
Embodiment two
The communication network of communication network in the present embodiment and embodiment one is roughly the same, and difference is that embodiment two mainly is applicable to the situation of packet data switched network networking more complicated.
Main frame in travelling carriage and packet data switched network uses single name server can cause slower response speed more for a long time.Provide single packet data switched network to carry out communication end to end between all travelling carriages for all users such as operator, then single name server obviously can't meet the demands, and just needs to adopt distributed enquiring method this moment.
See also Fig. 4, in the packet data switched network 140, be provided with center name server 151 and gateway name server (GW-DNS) 152,153.Wherein, gateway name server 152 and 153 is positioned at same level, has different analytical ranges; Center name server 151 is positioned at the last layer level of gateway name server 152 and 153, forms distributed name server structure.
When certain the subordinate's name server that is arranged in distributed name server structure is received query requests, if the domain name of request inquiry does not belong to the analytical range of this machine, will be to the address that the name server of this scope of parsing is responsible in high level name server inquiry, after the answer of receiving higher level's name server, send the domain name mapping request to the name server of the corresponding analytical range of its indication.
Seeing also Fig. 5, is the structured flowchart of gateway name server shown in Figure 4.This gateway name server 152 comprises memory cell 521, segmenting unit 522 and resolution unit 523; Wherein, memory cell 521 is integrated in the resolution unit 523, and segmenting unit 521 links to each other with memory cell 521 with resolution unit 523.
The user ID that described segmenting unit 522 is used for the travelling carriage that will receive is converted to corresponding domain name, and sends to resolution unit 523.Wherein, domain name is to construct according to the user ID of travelling carriage.
Described resolution unit 523 is used for inquiring about according to domain name the corresponding relation of aforementioned user ID and IP address, obtains the IP address of coupling.
In addition, in order to accelerate response speed to the high domain name of some frequencies of utilization, the buffer (figure does not show) that is used for writing down nearest domain name of inquiring about and corresponding IP address can also be set in resolution unit 523, during domain name after resolution unit 523 is received decomposition, have or not corresponding record in can first query caching device, if having then can directly reply query node.
In addition, judging unit (figure do not show) can also be set in gateway name server 152, be used to judge whether the domain name after the decomposition belongs to the analytical range of this gateway name server; Certainly, described arbitration functions also can be integrated in the resolution unit 523.If the domain name after decomposing belongs to the analytical range of this gateway name server, then parse the IP address of this domain name and respond the node of giving the request inquiry by resolution unit 523; If the domain name after decomposing is not the analytical range of this gateway name server, domain name after then will decomposing is according to the indication of center name server 151, send to other gateway name servers of corresponding analytical range, parse the IP address of this domain name correspondence by this gateway name server.
Because present embodiment adopts distributed name server structure, even main frame in the packet data switched network 140 and travelling carriage are many again, user ID does not have problem on the performance to the domain name mapping of IP address yet.Segmentation to user ID will be carried out according to actual conditions, consider the factor such as performance, network connection of number of users, this gateway name server of this segment identification.
Need to prove that the gateway name server can be made of many data processing equipments, part is finished fragmentation feature, and part is finished analytical capabilities.
Be appreciated that the name server among the embodiment also can adopt the gateway name server.
When user ID adopts the international mobile subscriber number, the international mobile subscriber number can be decomposed, as ms8613812345678 is decomposed into ms5678.1234.138.86, according to the decomposing scheme of international mobile subscriber number different stage is set with the name server.For example worldwide highest level center name server can be according to CC (Country Code, national code) is provided with, the rank setting that following domain name service rises can be decided in its sole discretion according to actual conditions by each country: for example can second level name server (first order gateway name server) be set according to the Service Dialing Numbers section, by operator's intercom number section third level name server is set again, the quantity of name servers at different levels and the analytical range of each name server can be disposed by operator.
Please consult Fig. 4 once more, the international mobile subscriber number of supposing travelling carriage 1 in the communication network is 8613812345678, and the international mobile subscriber number of travelling carriage 2 is 8613911223344, and the international mobile subscriber number of travelling carriage 3 is 8613855667788; Gateway name server 152 is responsible for the domain name mapping of 86138 number segments, and gateway name server 153 is responsible for the domain name mapping of 86139 number segments, and other number segments are resolved by other gateway name servers; And the user who activates on the gateway GPRS node 131 uses gateway name server 152, and the user who activates on the gateway GPRS node 132 uses gateway name server 153 to carry out domain name mapping.
Travelling carriage 2 and travelling carriage 3 all activate on gateway GPRS node 132, and the domain name server information of acquisition is identical.When travelling carriage 3 visit travelling carriages 2, at first to gateway name server 153 nslookup ms8613911223344; Gateway name server 153 is decomposed into ms11223344.86139 with domain name earlier, the territory of additional again place packet data switched network, and then the domain name of travelling carriage 2 becomes ms11223344.86139.abcpdn.net.Because gateway name server 153 is responsible for the parsing in 86139.abcpdn.net territory just, therefore directly in the 153 inner inquiries of gateway name server, and return results gives travelling carriage 3, and travelling carriage 3 can send messages to travelling carriage 2 by the IP address of travelling carriage 2 afterwards.
When travelling carriage 3 visit travelling carriages 1, to gateway name server 153 nslookup ms8613812345678, gateway name server 153 is decomposed into ms12345678.86138 with domain name earlier, the territory of additional place packet data switched network, the domain name of travelling carriage 1 becomes ms12345678.86138.abcpdn.net, gateway name server 153 can at first inquire about whether the domain name of this main frame and the corresponding informance of its IP address are arranged in the buffer of this machine, if IP address from travelling carriage 1 to travelling carriage 3 that just directly return is arranged; If do not have, will be to the host domain name of gateway name server 152 request analysis travelling carriages 1, behind the analysis result of receiving gateway name server 152, gateway name server 153 can send the IP address of travelling carriage 1 to travelling carriage 3, preserves the domain-name information of travelling carriage 1 simultaneously in the buffer of this machine.Behind the IP address that obtains travelling carriage 1, travelling carriage 3 just can directly send message to travelling carriage 1.
In the reality, if necessary, MSISDN can also repeatedly split, and for example travelling carriage 1 can split into ms5678.1234.138.86.
Embodiment three
See also Fig. 6, if adopt nontransparent access way between travelling carriage and the network, for example adopt RADIUS (Remote Authentication Dial In User Serveice, the long-distance user dials in certificate server) authentication, then can adopt embodiment 3 to finish the configuration of corresponding relation.
To nontransparent APN (Access Point Name, APN), when PDP activates, the gateway GPRS node can carry out operations such as authentication, charging to certificate server 160, owing to carried MSISDN information in the RADIUS authentication request, therefore certificate server 160 has obtained MSISDN and corresponding PDPIP address like this.Certificate server 160 is issued the gateway GPRS node with MSISDN and IP address, so the gateway GPRS node can generate the host domain name record automatically.
Need to prove that what travelling carriage used among the present invention is static ip address, all is satisfiable for this requirement of most of networkings.If packet data switched network adopts IPv6 (6, the 6 editions Internet Protocols of Intemet Protocolversion) technology, because IPv6 has huge address space, the use static ip address will be without any problem.
Be appreciated that, the present invention not only can be applied in the GPRS based on GSM, and can be applied in the GPRS based on WCDMA (Wide Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA)) network, this does not give unnecessary details.
The above only is a preferred implementation of the present invention, does not constitute the qualification to protection range of the present invention.Any any modification of being done within the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included within the claim protection range of the present invention.
