Problems solved by technology

[0004] However, if the service server is an IPv4 service server (a service server that can only use the IPv4 protocol), then the IPv6 data message sent by the IPv4v6 UE needs to be converted by NAT64 to obtain an IPv4 data message before it can be transmitted to the IPv4 service server, adding NAT64 network load

Abstract

An embodiment of the present invention provides an Internet Protocol address allocation method and device, wherein the device includes: a sending unit and a receiving unit, the sending unit is used to send a first PDN connection activation request message to the serving gateway, the first PDN connection activation request message Including PDP type indication information, the PDP type indication information is used to indicate that the PDP type is IPv4v6; the receiving unit is used to receive the first PDN connection activation response message sent by the serving gateway, and the first PDN connection activation response message includes the IP address of the UE and the first For the IP address of the DNS, the first DNS stores the IPv4 address of the IPv4 service server but does not store the IPv6 address of the IPv4 service server, and the IPv6 address of the IPv4 service server is a 4 to 6 address. The data packets transmitted between the UE and the IPv4 service server do not need to be converted by NAT64, thereby reducing the network load of NAT64 and improving the efficiency of data transmission.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular, to an Internet Protocol address allocation method and device. Background technique [0002] With the technological evolution of Internet Protocol Version 6 (IPv6 for short), IPv4 networks and IPv6 networks coexist in communication networks, and communication network operators deploy IPv6 and IPv4 Network Address Translation (NAT) in the network Address Translation IPv6-to-IPv4, referred to as: NAT64), and IPv6 and IPv4 address translation domain name server (Domain Name Server IPv6-to-IPv4, referred to as: DNS64), so that IPv6 user equipment (User Equipment, referred to as: UE) ( UEs that can only use the IPv6 protocol) and IPv4v6 UEs (UEs that can use both the IPv4 protocol and the IPv6 protocol) can access the IPv4 service server. [0003] In the prior art, the specific process for the IPv4v6 UE to access the IPv4 service server is: the IPv4v6...
