The technical solutions of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 2, the method for the base station to acquire and configure network parameters includes the following steps:

Step 1: When the base station is powered on, broadcast and send a DHCP Discover message, and set a timer T1, and the message carries information such as the MAC address of the base station. If the DHCP Offer message returned by the DHCP server is received before T1 times out, then perform step 2; otherwise, perform step 6;

Step 2: The base station verifies the received DHCP Offer message, which contains the IP address and other relevant configuration information;

Assuming that there is more than one DHCP server in the network where the base station is located, the identification information of the DHCP server that can assign network parameters to the base station needs to be set in advance. Taking the identification information as zte001 as an example, the base station checks the received DHCP Offer message to determine whether the identification information of the DHCP server carrying the DHCP Offer message carried in the message is zte001; Parse the IP address and other related configuration information in the message, and perform step 3; otherwise, discard the message, and after all DHCP Offer messages received before T1 timeout are discarded, perform step 6;

Step 3: The base station broadcasts and sends the DHCP Request message, and sets the timer T2. Wherein, the broadcast message may include the identification information of the DHCP server that assigns the network parameters to it, the IP address information assigned to it, and the like. If the base station receives the DHCP Ack message replied by the DHCP server that assigns network parameters to it before T2 expires, then perform step 4; otherwise, perform step 6;

Step 4: The base station checks the received DHCP Ack message. The check process can be that the base station judges whether all required network parameters are included in the DHCP Ack message, whether the IP address assigned by the DHCP server is available, etc. If the verification is correct, step 5 is performed; if the verification is wrong, a DHCP Decline message is sent to the DHCP server, and step 6 is performed;

Step 5: The base station judges whether the network parameters have been configured. If not, continue to judge whether the obtained network parameters are the same as the network parameters saved in Flash. If they are the same, directly configure the obtained network parameters to the base station. , and report to the main control module in the base station that the BRS (Bear subsystem, bearer subsystem) has been pre-powered successfully, and the process of configuring network parameters is over;

If it is judged that the network parameters are not configured by itself, and the obtained network parameters are different from the network parameters saved in the Flash, the base station configures the obtained network parameters to the base station, and updates and saves them in the Flash, and reports to the master The module reports that the BRS pre-power-on is successful, and the process of configuring network parameters is over;

If the base station judges that the network parameters have been configured by itself, it will further judge whether the obtained network parameters are the same as the network parameters saved in the Flash, if they are the same, the network parameter configuration process ends; if they are different, the obtained network parameters are written to In Flash and restart the base station, execute step 1;

Step 6: Determine whether the base station has configured network parameters. If configured, continue to step 1 after a delay of S1 or directly execute step 1; if not configured, execute step 7;

Step 7: Obtain the network parameters saved in Flash, in two cases:

a. If the base station obtains the network parameters from the Flash and configures them successfully, it sends a BRS pre-power-on success message to the main control module, and proceeds to step 1 after a delay of S1;

b. If the base station fails to obtain the network parameters from the Flash or fails to configure the network parameters, it will judge whether the BRS pre-power on is successful. If the BRS pre-power on fails, it will reply the BRS pre-power-on failure message to the main control module, and after a delay Proceed to step 1 after S2; if the BRS is pre-powered on successfully, proceed to step 1 after a delay of S2.

Described Dynamic Host Configuration Protocol server is used for after receiving described DHCP discovery message, in described corresponding relation, search corresponding IP address and other relevant configuration information according to the identification information of the described base station of carrying in this message, and this IP address that finds and other relevant configuration information are carried at the described DHCP that replies to described base station provide in the message.

12., it is characterized in that as claim 10 or 11 described systems:

Be preset with the identification information of this Dynamic Host Configuration Protocol server in the DHCP option 43 of described Dynamic Host Configuration Protocol server, and be preset with the identification information of the Dynamic Host Configuration Protocol server that can be this base station assigns network parameter in the described base station;

Described Dynamic Host Configuration Protocol server also is used for providing message also to carry the identification information of this Dynamic Host Configuration Protocol server at the DHCP that replys to described base station;

Correspondingly, described base station is used for after receiving that DHCP provides message, if it is consistent with the identification information of the local Dynamic Host Configuration Protocol server of presetting to judge the identification information of the Dynamic Host Configuration Protocol server that this message carries, then obtain IP address and other relevant configuration information of carrying in this message.

13. the system of a base station configuration network parameter comprises:

The base station is used for broadcast transmission DHCP (DHCP) and finds message; After also being used to receive that DHCP provides message, obtain IP address and other relevant configuration information of carrying in this message; Also be used for broadcast transmission DHCP request message, wherein carry the identification information that distributes the Dynamic Host Configuration Protocol server of described IP address and other relevant configuration information for it at least; Also be used for after receiving the dhcp response message that described Dynamic Host Configuration Protocol server is replied, the described IP address that gets access to and other relevant configuration information be configured to as yet on this base station of configuration network parameter not;

Dynamic Host Configuration Protocol server after being used to receive described DHCP and finding message, is replied DHCP to described base station message is provided, and wherein carries IP address and other relevant configuration information into described base station assigns; Also be used for after receiving the DHCP request message that carries self identification information, reply the dhcp response message.

14. system as claimed in claim 13 is characterized in that:

Described base station is used for after receiving the dhcp response message that described Dynamic Host Configuration Protocol server is replied, if judge this base station configuration network parameter not as yet, and the described IP address that gets access to and other relevant configuration information are identical with IP address and other relevant configured parameters that preserve this base station, then the described described IP address that gets access to and other relevant configured parameters are configured on this base station; If judge this base station configuration network parameter not as yet, and the described IP address that gets access to and other relevant configuration information are different with IP address and other relevant configured parameters that preserve this base station, then the described described IP address that gets access to and other relevant configured parameters are configured on this base station, and update stored on this base station.

15., it is characterized in that as claim 13 or 14 described systems:

Described base station also is used for after receiving the dhcp response message that described Dynamic Host Configuration Protocol server is replied, if judge this base station configuration network parameter, be used to also then judge whether the described IP address and other relevant configuration information that get access to be identical with IP address and other relevant configured parameters of this base station preservation, if identical, then layoutprocedure finishes; If different, then are used for the described described IP address that gets access to and other relevant configuration information are updated stored in this base station, and restart this base station.

16. system as claimed in claim 13 is characterized in that:

Described base station also is used for starting timer respectively when sending described DHCP discovery message and DHCP request message;

Described base station also is used for when corresponding timer expiry, do not provide message or dhcp response message if still receive the DHCP that described Dynamic Host Configuration Protocol server is replied, whether the described DHCP that perhaps receives provides message or dhcp response message mistake, then judge this base station configuration network parameter; If dispose, then be used for initiating again configuration network parameter flow process; If configuration, after then being used for obtaining the network parameter of preservation and being configured on this base station success, initiate configuration network parameter flow process again from this base station; If obtain the network parameter failure of preservation or dispose this network parameter failure, then be used for initiating again configuration network parameter flow process.
