Embodiment 1

[0047] Figure 4 It is a process in which the user equipment obtains IP configuration parameters through DHCP in the process of initially attaching to the 3GPP core network. Wherein, the trusted non-3GPP IP access network supports a DHCP server function. The process of establishing a binding relationship (that is, the binding relationship between the proxy address of the MAG and the home address of the user equipment) between the MAG (the trusted non-3GPP IP access network can provide the MAG function) and the LMA (the P-GW can provide the LMA function) , the MAG carries the request IP configuration parameter movement option in the PBU message (step 305), and requests the IP configuration parameter of the user equipment from the LMA. Here, when the MAG does not receive the DHCPv4 / v6 request message (request IP configuration parameters) sent by the user equipment, it obtains the IP configuration parameters in advance in the initial binding process. , the corresponding DHCPv4 / ...

Embodiment 2

[0063] Figure 5 It is the process of obtaining IP configuration parameters through DHCP after the user equipment completes the process of initially attaching to the 3GPP core network. Here, the trusted non-3GPP IP access network sends a PBU message to the P-GW to obtain the IP configuration parameters after receiving the IP configuration parameter request (that is, the DHCPv4 / v6 request message) from the user equipment. Specific steps are as follows:

[0064] Step 501, the user equipment completes the initial attachment to the 3GPP core network through the trusted non-3GPP IP access network, and the specific implementation is the existing technology, which will not be repeated here.

[0065] Step 502, the user equipment sends a DHCPv4 / v6 request message to a trusted non-3GPP IP access network (as a DHCP server) to request IP configuration parameters.

[0066] In step 503, the trusted non-3GPP IP access network (as the MAG) sends a PBU message to the P-GW, and the message ca...

Abstract

The invention discloses a method for obtaining an IP configuration parameter and a system thereof. The method comprises the following steps: a trusted non-3GPP (Third Generation Partnership Project) IP access network sends a proxy binding update (PBU) message to a packet data network gateway (P-GW), requests an IP configuration parameter of user equipment; the P-GW sends a proxy binding acknowledgement (PBA) message to the trusted non-3GPP IP access network and issues the IP configuration parameter of the user equipment. According to the method and the system in the invention, a problem that in an S2a interface scene of a proxy mobile IP v6 protocol (PMIPv6) the trusted non-3GPP IP access network as a dynamic host configuration protocol (DHCP) server can not provide the IP configuration parameter for the user equipment is solved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for acquiring IP configuration parameters. Background technique [0002] 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) Evolved Packet System (EPS, Evolved Packet System), such as figure 1 The EPS network architecture diagram shown in the non-roaming scenario consists of the Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network), the Mobility Management Unit (MME, Mobility Management Entity), and the service gateway (S-GW, Serving Gateway), packet data network gateway (Packet Data Network Gateway, referred to as P-GW or PDN GW), home subscriber server (HSS, Home Subscriber Server), policy and charging rule function (PCRF, Policy and Charging Rules Function) entity, Authentication Authorization Accounting (AAA, Authentication Authorization Accounting) server and other supporting ...
