Abstract

The present invention discloses a method and device for transmission self-configuration in a Self-Organized Network (SON), said method includes: a Dynamic Host Configuration Protocol (DHCP) client reporting a device identifier of this DHCP client to a DHCP server; said DHCP server configuring a transmission parameter for said DHCP client according to said device identifier, and sending said transmission parameter down to said DHCP client, said transmission parameter at least including an IP address of said DHCP client; and said DHCP client performing self-configuration according to said transmission parameter. The present invention uses the device identifier to allocate a fixed IP address, which is able to overcome the drawbacks caused by using the MAC address to allocate the fixed IP, and has a very strong maintainability.

Claims

1. A method for transmission self-configuration in a Self-Organized Network (SON), which comprises:

a Dynamic Host Configuration Protocol (DHCP) client reporting a device identifier of this DHCP client to a DHCP server;

said DHCP server configuring a transmission parameter for said DHCP client according to said device identifier, and sending said transmission parameter down to said DHCP client, said transmission parameter at least including an IP address of said DHCP client; and

said DHCP client performing self-configuration according to said transmission parameter.

2. The method according to claim 1, wherein,

said transmission parameter further includes a Stream Control Transport Protocol (SCTP) port number of said DHCP client, an IP address and a SCTP port number of a Mobile Management Entity (MME);

the method further comprises;

said DHCP client performing to establish a link with a SCTP of the MME according to said transmission parameter, and completing transmission self-establishment.

3. The method according to claim 1, further comprising:

said DHCP client setting a trusted DHCP server identifier;

when said DHCP server sends said transmission parameters down to the DHCP client, further sending a self-identifier to said DHCP client; and

said DHCP client performing authentication according to a received DHCP server identifier before using said transmission parameter to perform the self-configuration, and using said transmission parameter to perform the self-configuration until confirming that this received DHCP server identifier belongs to the trusted DHCP server identifier.

4. The method according to claim 3, further comprising:

after confirming that said DHCP server identifier belongs to the trusted DHCP server identifier, said DHCP client sending a DHCP message to the DHCP server, and confirming that an IP address of the DHCP client is occupied.

5. The method according to claim 3, further comprising:

said DHCP client and DHCP server pre-appointing predetermined meanings of a DHCP message option fields;

in the step of the DHCP client reporting the device identifier of this DHCP client to the DHCP server, said DHCP client including the device identifier of this DHCP client through pre-appointed DHCP message option fields, and reporting the device identifier of this DHCP client to said DHCP server;

in the step of said DHCP server sending the self-identifier to said DHCP client, said DHCP server including the self-identifier through pre-appointed DHCP message option fields, and sending the self-identifier to said DHCP client.

6. The method according to claim 5, wherein,

in the step of sending the transmission parameter down to said DHCP client, said DHCP server includes said transmission parameter through pre-appointed DHCP message option fields, and sends the transmission parameter to said DHCP client.

7. The method according to claim 1, wherein,

the DHCP server is set with a corresponding table of the device identifier and the transmission parameter;

in the step of configuring the transmission parameter for said DHCP client, said DHCP server configures the transmission parameter for said DHCP client according to said corresponding table.

8. A Dynamic Host Configuration Protocol (DHCP) client for supporting transmission self-configuration in a Self-Organized Network (SON), and said DHCP client being set to:

report a device identifier of this DHCP client to DHCP server;

perform self-configuration according to a transmission parameter sent by a DHCP server, and perform to establish a link with a Stream Control Transport Protocol (SCTP) of a Mobile Management Entity (MME).

9. The DHCP client according to claim 8, said DHCP client being further set to:

set a trusted DHCP server identifier, perform authentication according to a received DHCP server identifier, and use said transmission parameter to perform self-configuration only if the received DHCP server identifier belongs to the trusted DHCP server identifier.

10. A Dynamic Host Configuration Protocol (DHCP) server for supporting transmission self-configuration in a Self-Organized Network (SON), and the DHCP server being set to:

configure a transmission parameter for a DHCP client according to a device identifier of the DHCP client, and send the transmission parameter down to said DHCP client so that said DHCP client performs self-configuration according to said transmission parameter and performs to establish a link with a Stream Control Transport Protocol (SCTP) of a Mobile Management Entity (MME).

11. The DHCP server according to claim 10, the DHCP server being further set to:

when sending the transmission parameter down to DHCP client, send a self-identifier to said DHCP client so that said DHCP client performs authentication according to said identifier.

12. A device for transmission self-configuration in a Self-Organized Network (SON), which comprises a Dynamic Host Configuration Protocol (DHCP) client and a DHCP server, wherein,

the DHCP client is set to:

report a device identifier of this DHCP client to a DHCP server, and perform self-configuration according to a transmission parameter sent by the DHCP server;

said DHCP server is set to;

configure the transmission parameter for said DHCP client according to the device identifier, and send the transmission parameter down to said DHCP client so that said DHCP client performs self-configuration according to said transmission parameter;

said transmission parameter at least includes an IP address of said DHCP client.

13. The device according to claim 12, wherein,

said transmission parameter further includes a Stream Control Transport Protocol (SCTP) port number of said DHCP client, and an IP address and a SCTP port number of a Mobile Management Entity (MME);

said DHCP client is further set to;

perform to establish a link with a SCTP of the MME according to said transmission parameter, and complete transmission self-establishment.

14. The device according to claim 12, wherein,

said DHCP client is further set to:

set a trusted DHCP server identifier, and perform authentication according to a received DHCP server identifier, and use the transmission parameter to perform self-configuration only if the received DHCP server identifier belongs to trusted DHCP server identifier;

the DHCP server is further set to;

send a self-identifier down to the DHCP client when sending transmission parameters down to the DHCP client so that said DHCP client performs authentication according to said identifier.
