Description
Technical field
The present invention relates to the communications field, in particular to a kind of acquisition methods and device of the configuration information based on dynamic host allocation protocol.
Background technology
Dynamic host allocation protocol (Dynamic Host Configuration Protocol, abbreviate DHCP as) be transmission control protocol/Internet protocol (Transmission ControlProtocol/Internet Protocol, abbreviate TCP/IP as) a kind of in the protocol family, the RFC standard is 2131, mainly is to be used for distributing dynamic IP address to net computer.These assigned IP address all are the address set of being made up of a plurality of addresses that Dynamic Host Configuration Protocol server keeps in advance, and they generally are one section continuous addresses.Present Dynamic Host Configuration Protocol server has three kinds of address distribution, comprising: manual assignment, distribute and dynamic assignment automatically.In above-mentioned three kinds of assigning process, it all is to carry out according to the message negotiation process that is illustrated in fig. 1 shown below that dhcp client obtains the IP address.
Fig. 1 is the schematic diagram according to the DHCP message negotiation process of correlation technique, in the existing DHCP message negotiation process as shown in Figure 1, adopt DHCPDISCOVER (DHCP finds message), DHCPOFFER (DHCP response message), DHCPREQUEST (DHCP request message) and DHCPACK (DHCP confirmation message) four steps message interaction to finish the negotiations process of DHCP.Fig. 2 is the DHCP message format according to correlation technique, and wherein, the DHCP message format defines as shown in Figure 2.
Is example with Windows 2000Server commonly used as Dynamic Host Configuration Protocol server, mainly contains the relational language and the notion of following three Dynamic Host Configuration Protocol server ends configuration:
1) action scope (Scope): Windows 2000 with the service unit of Dynamic Host Configuration Protocol server be subnet.To each subnet of serving, define an action scope and (comprise subnet net IP address, mask, configurations such as assignable IP address pool, gateway, route, DNS), when the dhcp client in the serviced subnet sends DHCPDISCOVER when request, in the IP address pool of the action scope of correspondence, select available IP address to respond.
2) user class (user class): can define user class and come specific dhcp client or client sets definition distributed to their specific configuration parameter (such as gateway, route, DNS etc.).The option of Windows 2000DHCP SERVER user class correspondence is option 77, applicating example: in the DHCPDISCOVER request message that dhcp client sends, carry option 77, wherein insert the self-defined content that can identify this client, as " client1 "; Also needing to dispose accordingly on the Dynamic Host Configuration Protocol server of this client service, the user class of " client1 " of a correspondence of definition in the action scope under this client carries out the configurations such as gateway, route, DNS of appointment to " client1 " user class.Therefore, the dhcp client that client1 identified gets access to configuration datas such as gateway into own appointment, route, DNS from server.
3) keep: can in Windows 2000DHCP SERVER, use media interviews control (Medium Access Control, abbreviate MAC as) the next unique dhcp client of sign in address, and distribute to this client specific I P address, promptly usually said MAC Address is bound.
In existing standard negotiation flow process, be reached for the purpose that the client of appointment is distributed the configuration parameter of appointment, general way is to adopt the MAC Address of dhcp client to be used as differentiation between different clients, utilizes the method for MAC Address binding to realize.But, under wireless side equipment in mobile radio communication (such as base station equipment etc.) this specific application scenarios of MANET, each BTS network element of base station system is as dhcp client, when the configuration of obtaining appointment to Dynamic Host Configuration Protocol server comes networking, following two special demands arranged:

2) each BTS network element of base station system not only needs to get access to its own IP address, just can finish the networking layoutprocedure after also needing simultaneously to get access to the IP address information of other network elements (BSC network element, background system OMC etc.).
Is example with Windows 2000Server commonly used as Dynamic Host Configuration Protocol server, and for the special applications scene in the above-described mobile radio communication, the DHCP of existing standard consults to have following limitation:
1) different MAC Address can't with same IP address binding, can not satisfy the demand of different MAC Address being distributed the IP address of identical appointment.
2) adopt the method for MAC Address binding can only distribute the IP address of appointment for the dhcp client of appointment, but, then can't satisfy other configuration informations except that self IP address that each dhcp client distributed appointment for needed other configuration informations of dhcp client.For example, when certain dhcp client A belongs to action scope A (i.e. subnet) on the server A that service is provided for it, on server A with behind the MAC Address of customer end A and certain the IP address binding among the action scope A, after the DHCP of standard consults to finish, server A has been distributed the IP address of appointment to this customer end A, but other configuration informations such as gateway, route etc. then are to be that unit distributes with the action scope.Be under this kind mode, other configuration informations that dhcp client obtained that belong in the same subnet are identical, non-appointment.
In addition,, also can adopt the different user class of (i.e. action scope) definition in a subnet, come to be each base station assigns specified message for Windows 2000Server; Yet the information of carrying in the yiaddr field in the DHCPOFFER message is automatic IP address allocated from the address pool of Dynamic Host Configuration Protocol server in this case, the IP address of promptly distributing to dhcp client is non-appointment, therefore, also can't satisfy the demand of distributing the configuration data of appointment for the dhcp client of appointment.
Can not satisfy the demand of different MAC Address being distributed the IP address of identical appointment at correlation technique, adopt the method for MAC Address binding can't satisfy other configuration informations except that self IP address that each dhcp client distributed appointment, and can't satisfy the problem of distributing the configuration data of appointment for the dhcp client of appointment, effective solution is not proposed at present as yet.
