Abstract

The invention discloses an IP address allocation method and a system, which are used for determining the types of IP addresses allocated to user equipment (UE) by local networks through a user mobile control management entity in the PDNGW (Public Data Network Gate Way) and GGSN (Gateway GPRS Support Node) local networks without core networks and allocates the IP addresses of the type to the user equipment (UE). The IP address allocation method comprises the following steps that the user mobile control management entity requests the accessed information of the local networks according to the user equipment (UE) to indicate a home NodeB to access the user equipment (UE) to the local networks through establishing the radio bearers of the local networks; the user mobile control management entity determines the types of the IP addresses allocated to the user equipment (UE) by the local networks and indicates the user equipment (UE) to acquire the IP address of the type from the home NodeB;and the home NodeB allocates the information of the IP addresses according to a request sent by the user equipment (UE) and allocates the IP addresses for the user equipment (UE).

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to an Internet Protocol (IP, Internet Protocol) address allocation method and system. Background technique

[0002] In the Evolved Packet System (EPS, Evolved Packet System), version 4 of the Internet Protocol (IPv4) and version 6 of the Internet Protocol (IPv6) are supported.

[0003] The solution for obtaining an IP address by a user equipment (UE) in the prior art includes:

[0004] The UE initiates the establishment of the PDN connection of the SGi interface or the Gi interface;

[0005] The UE sends the type information of the IP address requested to be allocated to the network side, that is, the UE requests the network side to allocate an IPv4 address and / or an IPv6 address.

[0006] After receiving the type information of the IP address requested by the UE, the user mobility control management entity on the network side may further modify the type information of the ...
