example 1

[0036] Example 1: The DHCP server receives a DHCP message sent by a DHCP client and includes a server option carrying an operator identifier to which the server belongs, where the server option carrying the operator identifier of the server is a server domain name option or a server IP address option.

example 2

[0037] Example 2: The DHCP server receives a DHCP message sent by a DHCP client through a DHCP relay and includes a server option carrying an operator identifier to which the server belongs, where the server option carrying the operator identifier of the server is a server domain name option or a server IP address option.

[0038] The DHCP client may be a user equipment UE, and the DHCP relay may be a packet data network gateway PGW. Depending on the specified domain server to be discovered, the server options are also different. If the server is ANDSF, the server option can be the ANDSF option; if the server is PCSCF, the server option can be the PCSCF option. If the domain name of the specified domain server needs to be returned, the ANDSF option or the PCSCF option is the server domain name option. If the IP address of the specified domain server needs to be returned, the ANDSF option or the PCSCF option is the server IP address option.

[0039] In example 2, the DHCP relay...

Abstract

The embodiment of the invention relates to a method, a system and equipment for discovering a server, wherein the server discovering method comprises the following steps: receiving a dynamic host configuration protocol DHCP message which comprises a server option carrying a server belonging carrier identification code; and returning a DHCP response message corresponding to the server option carrying the server belonging carrier identification code. The DHCP response message comprises a domain name or an IP address of a specified domain server acquired according to the server belonging carrier identification code. The method, the system and the equipment can acquire the domain name or the IP address of the specified domain server by carrying the server belonging carrier identification code in the server option of the DHCP massage so as to discover the random specified domain server.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a server discovery method, system, and device. Background technique [0002] Existing network discovery of servers through Dynamic Host Configuration Protocol (DHCP) is limited to discovering the DHCP server in the current domain, and can only provide server configuration information in the current domain, and cannot query the server configuration of other specified domains other than the current domain. information, that is, it cannot assist the UE to discover servers in other specified domains. [0003] Take the discovery of an access network discovery and selection function (Access network discovery and selection function; ANDSF for short) server through DHCP as an example. The ANDSF can assist user equipment (User Equipment; UE for short) to perform access network discovery and selection. The ANDSF provides two types of information for th...
