Abstract

The invention discloses a method and a device for obtaining a PGW FQDN, which relate to the field of communication technologies and can solve the problem that the FQDN of the PGW cannot be obtained due to missing parameters or incorrect APN-FQDN construction. The method of the present invention includes: when the user equipment switches the communication system, the MME obtains the PGW IP address corresponding to the user equipment from the original SGSN, the MME is used for the user equipment to connect the user equipment and the core network after switching the communication system, and the original SGSN is used for the user equipment. Connect the user equipment and the core network before switching the communication system; the MME obtains the FQDN corresponding to the PGW IP address from the DNS server, the DNS server is used to store the reverse resolution record of the PGW IP address, and the reverse resolution record is used to find the FQDN according to the PGW IP address. The present invention is applicable to the acquisition process of the PGW FQDN.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for obtaining PGW (English: PDN Gateway, Chinese: Packet Data Gateway) FQDN (English: Fully Qualified Domain Name, Chinese: Full Name Domain Name). Background technique [0002] With the development of communication technology, EPS (English: Evolved Packet System, Chinese: Evolved Packet System) is widely used. Such as figure 1 As shown, EPS is composed of user equipment, access network and core network. User equipment can access the core network through UMTS (English: Universal Mobile Telecommunications System, Chinese: Universal Mobile Telecommunications System) such as UTRAN (English: UMTS Terrestrial Radio Access Network, Chinese: Universal Mobile Telecommunications System Terrestrial Radio Access Network) The SGSN (English: Serving GPRS Support Node, Chinese: Serving GPRS Support Node), and LTE such as E-UTRAN (English: Evolved UMTS Terre...
