Description
Technical field
The present invention relates to the IP address assignment technical field, be specifically related to obtain the method and the base station of service IP address.
Background technology
Along with the extensive use of the flourish and wireless network of internet service, support the mobile service of all-IP to receive much concern.The mobile subscriber how to utilize link level equipment that Access Network provides and Dynamic Host Control Protocol (DHCP) server adopt DHCP finish dynamic IP addressing distribution, rent, re-rent and discharge, also present wireless access network technology has been proposed challenge, these challenges mainly comprise: thus how access network equipment supports how mobile subscriber's IP application IP addresses process, access network equipment learn how IP address, the access network equipment of distributing to the mobile subscriber learn that IP application IP addresses/re-rent success or not determines to apply for/measure taked after re-renting failure.
DHCP supports following function: dynamic assignment IP address, static allocation IP address, rent the IP address, support forever to rent the IP address, recover to end rent IP address etc.In fact, DHCP is responsible for handling two kinds of master datas: rent i.e. promptly unappropriated, available IP address, address in IP address allocated and the address pool, address.
The dhcp client that Fig. 1 has provided the DHCP definition obtains the message flow sequential chart of IP address, and as shown in Figure 1, its concrete steps are as follows:
Step 101:DHCP client is found (DHCPDiscover) message to Dynamic Host Configuration Protocol server clean culture or broadcasting DHCP.
If dhcp client has the permanent IP of a renting address, then dhcp client can be carried at this permanent IP of renting address in the DHCP discovery message.
Step 102:DHCP server receives that this DHCP finds message, takes out an IP address and provide (DHCPOffer) message to return to dhcp client by DHCP this IP address from the address pool of self.
Step 103:DHCP client receives DHCP message is provided, thus obtain Dynamic Host Configuration Protocol server for self IP address allocated as its own IP address.
If dhcp client receives that a plurality of DHCP that carry the IP address from different Dynamic Host Configuration Protocol server provide message, then dhcp client can be selected one or select the permanent IP of the renting address of self asking arbitrarily in this a plurality of IP address.
Step 104:DHCP client sends DHCP request (DHCPRequest) message that carries the Dynamic Host Configuration Protocol server sign by the form of broadcasting or clean culture to Dynamic Host Configuration Protocol server, and wait-for-response.
Dynamic Host Configuration Protocol server identifies promptly, the pairing Dynamic Host Configuration Protocol server sign in IP address that dhcp client is finally selected.
Step 105:DHCP server receives and also to detect the DHCP request message, is not self identification if detect the Dynamic Host Configuration Protocol server sign that the DHCP request message carries, and then abandons this DHCP request message; Otherwise, accept this DHCP request message, and end as if not detecting to renting of dhcp client IP address allocated, then return a DHCP and confirm (DHCPAck) message to dhcp client; If end for renting of dhcp client IP address allocated, then returning a DHCP to dhcp client negates (DHCPNak) message.
Step 106:, then bring into use Dynamic Host Configuration Protocol server to distribute to its own IP address if dhcp client is received the DHCP confirmation message; If dhcp client receives that DHCP negates a message, then returns step 101; If dhcp client is found the Dynamic Host Configuration Protocol server IP address allocated and can't normally be used, then send DHCP cancellation (DHCPDecline) message, and return step 101 to Dynamic Host Configuration Protocol server.
Fig. 2 is the DHCP structure system under micro-wave access to global intercommunication (WIMAX) system, as shown in Figure 2, it mainly comprises: base station (BS), access service network gateway (ASN-GW), Dynamic Host Configuration Protocol server and portable terminal (MS), wherein, BS is used to provide MS to be connected with the L2 of self, and the management of realization Radio Resource etc.; ASN-GW provides relay function for Dynamic Host Configuration Protocol server and BS, and ASN-GW can be positioned on the same entity with Dynamic Host Configuration Protocol server, also can be positioned on the different entities; The DHCP server handles mainly that usefulness is re-rented in dynamic IP addressing application, IP address, dynamic IP addressing is distributed and the application of static ip address, re-rent, recovery etc.; MS is mainly used in and initiates the dynamic IP addressing application, initiates the IP address and re-rents and use etc., is equivalent to dhcp client.Wherein, Dynamic Host Configuration Protocol server links to each other by Interface R3 with ASN-GW, and BS links to each other by the R6 interface with ASN-GW, and BS links to each other by the R1 interface with MS, links to each other by Interface R4 between the ASN-GW.
According to IEEE 802.16d/e agreement, the initialization procedure of MS access network is as follows:
Step 01:MS scans down channel, and sets up synchronously with BS.
Step 02:MS describes (UCD) message by up channel and obtains up emission parameter from BS.
Step 03:MS carries out search procedure.
Step 04:MS executive capability is conferred process.Be defined as the MS that managed if confer MS in the process by BS, then execution in step 05～10 after this in this ability; If MS is defined as the MS that do not managed then after execution in step 05～06 by BS, directly execution in step 10.
Step 05～06:MS carries out authentication, registration process.
If confer in the process in ability, MS is defined as the MS that managed by BS, and then in registration process, BS distributes secondary management connection identifier (CID (CID) to MS.
Step 07:MS obtains management ip address from Dynamic Host Configuration Protocol server, is connected thereby set up IP with BS.
Here, because also, eating dishes without rice or wine between MS and the BS do not set up professional the connection, therefore, what MS obtained from Dynamic Host Configuration Protocol server is management ip address, and MS and BS interactive messages can only be carried on the management channels of secondary management CID correspondence as the dhcp discover message that MS sends etc. in setting up the process that IP connects, after BS receives the message that MS sends, if detect this message bearing on the management channels of management CID correspondence, then discern and transmit this message.Especially it is pointed out that the management ip address that MS obtains is mainly used in the management process of BS to MS.
Step 08:MS and BS realize the date time synchronized.
Step 09:MS and BS interworking parameter.
Step 10:MS sets up to preset to flow with BS and is connected, after this formal access network of MS.
From the above mentioned, in the prior art, during the MS access network, what obtain is the management ip address that is used for management process.But in actual applications, during networks such as MS access WIMAX networking or internet, also need obtain the service IP address that is used for service communication usually.But in present WIMAX related protocol, only provided the message process of MS acquisition service IP address, but when not providing MS access WIMAX network, before also not obtaining service IP address, how to set up described for obtaining the necessary bearer path of service IP address interactive messages.

User terminal among the present invention can be MS, also can be the downstream site of MS and MS.For the bearer path that obtains the mutual DHCP related news of service IP address specifically refers to, between MS and the BS bearer path that obtains the mutual DHCP related news of service IP address between user terminal of setting up among the present invention and the BS.Particularly, if user terminal is MS, initiate at first then that service IP address gives information, service IP address request message, service IP address cancellation message etc. or receive at last that service IP address gives information, the user terminal of service IP address acknowledge message, service IP address nack message etc. is MS; If user terminal is the downstream site of MS and MS, initiate at first then that service IP address gives information, service IP address request message, service IP address cancellation message etc. or receive at last that service IP address gives information, the user terminal of service IP address acknowledge message, service IP address nack message etc. is the downstream site of MS, and the forwards of the MS downstream site being initiated by MS is to Dynamic Host Configuration Protocol server, and perhaps the forwards of Dynamic Host Configuration Protocol server being sent by MS is to the downstream site of MS.
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
Embodiment one:
Fig. 3 is the flow chart that MS provided by the invention obtains the specific embodiment one of service IP address, and as shown in Figure 3, its concrete steps are as follows:
In the present embodiment, BS that sets up after initialization system powers on and the signalling path between the BS service node are supported the transmission of DHCP related news.
Step 301:MS and BS carry out registration process, and BS distributes secondary management CID to MS.
In the present embodiment, no matter confer in the process in ability, MS is defined as the MS that managed by BS and still is defined as the MS that do not managed by BS, and in registration process, BS will distribute secondary management CID to MS.
Particularly, BS can send to MS by registration response (REG-RSP) message to the secondary management CID that MS distributes.
Step 302:MS is carried on dhcp discover message on the management channels of the secondary management CID correspondence that BS distributes for self and sends to BS.
If MS has a permanent leased service IP address, then MS can directly be carried at this permanent leased service IP address in the dhcp discover message.
If MS has downstream site, then MS further comprises before sending dhcp discover message in step 302: the downstream site of MS sends dhcp discover message to MS.Simultaneously, if the downstream site of MS has a permanent leased service IP address, then the downstream site of MS can directly be carried at this permanent leased service IP address in the dhcp discover message
After step 303:BS received dhcp discover message, the signalling path that this dhcp discover message is set up when powering between self and the BS service node sent to the BS service node.
After step 304:BS service node is received this dhcp discover message, this dhcp discover message is forwarded to Dynamic Host Configuration Protocol server.
Step 305:DHCP server is received this dhcp discover message, and IP address of taking-up also gives information this IP address and returns to MS by DHCP from its own IP address pond.
Particularly, Dynamic Host Configuration Protocol server gives information this DHCP earlier and is back to the BS service node, signalling path between self and the BS that set up when powering on of BS service node gives information this DHCP and is back to BS then, afterwards, BS gives information this DHCP and returns to MS on the management channels that is carried on secondary management CID correspondence.
Step 306:MS receives this DHCP and gives information, thereby obtain the IP address that this DHCP gives information and carries, and determine that this IP address be the service IP address of self, and will carry the DHCP request message that Dynamic Host Configuration Protocol server identifies and send to Dynamic Host Configuration Protocol server through BS, BS service node.
If MS receives that a plurality of DHCP that carry the IP address from different Dynamic Host Configuration Protocol server give information, then MS can select one or select self to ask the service IP address of permanent IP address as self arbitrarily in this a plurality of IP address.
Dynamic Host Configuration Protocol server sign promptly, the sign of MS finally determines the pairing Dynamic Host Configuration Protocol server of service IP address of self.
Equally, the DHCP request message is carried on BS when transmitting between MS and BS be on the corresponding management channels of the secondary management CID that distributes of MS, when being carried on system when transmitting powering between BS and BS service node on the BS and the signalling path between the BS service node of foundation.
If MS has downstream site, after then MS receives that the DHCP that carries service IP address gives information, directly this DHCP is given information and be forwarded to the downstream site of MS, then, the downstream site of MS is determined the service IP address of this IP address for self, and the DHCP request message that will carry Dynamic Host Configuration Protocol server sign is sent to MS, and MS sends to Dynamic Host Configuration Protocol server with this DHCP request message through BS, BS service node then.Simultaneously, if the downstream site of MS receives that a plurality of DHCP that carry the IP address from different Dynamic Host Configuration Protocol server give information, then the downstream site of MS can be selected one or select self to ask the service IP address of permanent IP address as self arbitrarily in this a plurality of IP address.
After step 307:DHCP server is received the DHCP request message, judge and whether do not end for renting of MS IP address allocated, if, execution in step 308; Otherwise, execution in step 310.
If MS has downstream site, then in this step, DHCP judges to renting of the downstream site IP address allocated of MS whether do not end.
Step 308:DHCP server returns a DHCP acknowledge message by BS service node, BS to MS.
Equally, on the BS service node and the signalling path between BS that the DHCP acknowledge message was set up when being carried on system when transmitting powering between BS service node and BS, be carried on BS when between BS and MS, transmitting and be on the corresponding management channels of secondary management CID that MS distributes.
Step 309:MS receives the DHCP acknowledge message, the service IP address of then bringing into use Dynamic Host Configuration Protocol server to distribute, and this flow process finishes.
Further, can't normally use, then send a DHCP cancellation message to Dynamic Host Configuration Protocol server, and return step 302 by BS, BS service node if MS finds the Dynamic Host Configuration Protocol server IP address allocated.
Equally, DHCP cancellation message is carried on BS when transmitting between MS and BS be on the corresponding management channels of the secondary management CID that distributes of MS, when being carried on system when transmitting powering between BS and BS service node on the BS and the signalling path between the BS service node of foundation.
If MS has downstream site, after MS receives the DHCP acknowledge message, this DHCP acknowledge message is forwarded to the downstream site of MS, after the downstream site of MS is received this DHCP acknowledge message, the service IP address of bringing into use Dynamic Host Configuration Protocol server to distribute, this flow process finishes.
Step 310:DHCP server returns a DHCP nack message by BS service node, BS to MS, and MS receives the DHCP nack message, then returns step 302.
Equally, on the BS service node and the signalling path between BS that the DHCP nack message was set up when being carried on system when transmitting powering between BS service node and BS, be carried on BS when between BS and MS, transmitting and be on the corresponding management channels of secondary management CID that MS distributes.
If MS has downstream site, after MS receives the DHCP nack message, this DHCP nack message is forwarded to the downstream site of MS, the downstream site of MS returns step 302 after receiving this DHCP nack message.
Present embodiment can be at user terminal promptly: carry out after the registration process when MS or MS and downstream site access network thereof, can carry out simultaneously with the process that user terminal obtains management ip address, after user terminal obtained service IP address, service IP address that can user terminal identified the stream of after this setting up that presets.
Embodiment two:
Fig. 4 is the flow chart that MS provided by the invention obtains the specific embodiment two of service IP address, and as shown in Figure 4, its concrete steps are as follows:
Step 401:BS service node detects MS and succeeds in registration, and the business of then setting up at MS that is used for transport service presets stream, and the business of MS is preset stream information is sent to BS.
BS can return registration reply message to MS after MS succeeds in registration, notify succeeding in registration of BS service node MS simultaneously.
The business of the MS that step 402:BS sends according to the BS service node presets service quality (QoS) parameter and the self radio policy in resource management in the stream information, set up between self and the BS service node and self and MS between business preset stream, and all business that will set up preset stream information and send to MS.
If MS has downstream site, then MS can notify the downstream site business of MS to preset stream and set up successfully after receiving that business that BS sends presets stream information.And the business that detects the downstream site of MS presets stream and sets up successfully, then can preset the authentication process of stream information at the business of carrying that this business presets stream to the authentication server transmission, and after authentication passes through, send dhcp discover message to MS.
After step 403:MS receives that business presets stream information, preset the business of selecting the satisfied DHCP related news that obtain service IP address of a QoS to transmit requirement in the stream in all business that activated and preset stream.
Step 404:MS is carried on self selected business with dhcp discover message and presets stream and go up and send to the BS service node by BS.
If MS has downstream site, then MS further comprises before sending dhcp discover message in step 404: the downstream site of MS sends dhcp discover message to MS.
After step 405:BS service node is received this dhcp discover message, this dhcp discover message is transmitted to Dynamic Host Configuration Protocol server.
Step 406:DHCP server is received this dhcp discover message, and IP address of taking-up also gives information this IP address and returns to the BS service node by DHCP from its own IP address pond.
After step 407:BS service node receives that this DHCP gives information, this DHCP business between self and the BS of being carried on that gives information is preset and is sent to BS on the stream, BS presets DHCP the business between self and the MS of being carried on that gives information to be transmitted to MS on the stream afterwards.
Step 408:MS receives this DHCP and gives information, thereby obtain Dynamic Host Configuration Protocol server and distribute to its own IP address, and determine that this IP address is the service IP address of self, and the DHCP request message that will carry Dynamic Host Configuration Protocol server sign is carried on self selected business and presets and be sent to BS on the stream, BS is carried on business between self and the BS service node with the DHCP request message and presets and be sent to the BS service node on the stream afterwards, and the BS service node is transmitted to Dynamic Host Configuration Protocol server with this DHCP request message afterwards.
If MS has downstream site, after then MS receives that the DHCP that carries service IP address gives information, directly this DHCP is given information and be forwarded to the downstream site of MS.Then, the downstream site of MS determines that this IP address is self service IP address, and the DHCP request message that will carry the Dynamic Host Configuration Protocol server sign is sent to MS, and MS sends to Dynamic Host Configuration Protocol server with this DHCP request message through BS, BS service node then.
After step 409:DHCP server is received the DHCP request message, judge and whether do not end self for renting of MS IP address allocated, if, execution in step 410; Otherwise, execution in step 412.
If MS has downstream site, then in this step, DHCP judges to renting of the downstream site IP address allocated of MS whether do not end.
Step 410:DHCP server returns a DHCP acknowledge message by BS service node, BS to MS.
When the DHCP acknowledge message transmits between BS service node and BS, BS and MS, be carried between BS service node and the BS respectively, the business between BS and the MS presets on the stream.
Step 411:MS receives the DHCP acknowledge message, brings into use Dynamic Host Configuration Protocol server to distribute to the service IP address of self, and this flow process finishes.
Further, BS preserves the professional corresponding relation that presets the service IP address of traffic identifier and MS.
If MS has downstream site, after MS receives the DHCP acknowledge message, this DHCP acknowledge message is forwarded to the downstream site of MS, after the downstream site of MS is received this DHCP acknowledge message, the service IP address of bringing into use Dynamic Host Configuration Protocol server to distribute, this flow process finishes.
Further, can't normally use, then send a DHCP cancellation message, and return step 404 to Dynamic Host Configuration Protocol server if MS finds the Dynamic Host Configuration Protocol server IP address allocated.
When DHCP cancellation message transmits between MS and BS, BS and BS service node, be carried between MS and the BS respectively, the business between BS and the BS service node presets on the stream.
Step 412:DHCP server returns a DHCP nack message by BS service node, BS to MS, and MS receives the DHCP nack message, then returns step 404.
When the DHCP nack message transmits between BS service node and BS, BS and MS, be carried between BS service node and the BS respectively, the business between BS and the MS presets on the stream.
If MS has downstream site, after MS receives the DHCP nack message, this DHCP nack message is forwarded to the downstream site of MS, the downstream site of MS returns step 404 after receiving this DHCP nack message.
Embodiment three:
Fig. 5 is the flow chart that MS provided by the invention obtains the specific embodiment three of service IP address, and as shown in Figure 5, its concrete steps are as follows:
Step 501:BS service node detects succeeding in registration of MS, sets up a signaling that is used for the transmission of dhcp related news at MS and presets stream, and this signaling is preset stream information be sent to BS.
Particularly, the BS service node can preset signaling stream information and be sent to BS by resource reservation request (RR-Request) message.
The signaling that step 502:BS sends according to the BS service node presets qos parameter and the self radio policy in resource management in the stream information, set up between self and the BS service node and self and MS between signaling preset stream, and the signaling of setting up preset stream information be sent to MS.
Particularly, BS presets stream information by dynamic service flow increase request (DSA-REQ) message with signaling and is sent to MS, afterwards, MS returns dynamic service flow to BS increases response (DSA-RSP) message, and BS receives after this dynamic service flow increases response message and returns the dynamic service flow acknowledge message to MS.
If MS has downstream site, and the signaling that detects the downstream site of MS presets stream and sets up successfully, then the downstream site of MS can send the authentication process that signaling presets stream information of carrying that presets stream at this signaling to authentication server, and after authentication passes through, sends dhcp discover message to MS.
Here, MS can notify the downstream site signaling of MS to preset stream equally and set up successfully after receiving that signaling that BS sends presets stream information.
Step 503:MS is carried on this signaling with dhcp discover message and presets and be sent to BS on the stream, and BS is carried on signaling between self and the BS service node with this dhcp discover message and presets and send to the BS service node on the stream afterwards.
If MS has downstream site, then MS further comprises before sending dhcp discover message in step 503: the downstream site of MS sends dhcp discover message to MS.
