Embodiment 1

[0060] This embodiment describes when the UE is in a 3GPP access roaming scenario, and the 3GPP core network adopts the EPC architecture. When the UE initiates an IP-CAN session in a roaming area, the MME receives the user subscription information from the HSS, and after receiving the message, the MME selects a P-GW for the IP-CAN session, and the MME saves the PLMN ID information of the selected P-GW . The MME sends a response message of user subscription information to the HSS, and the message carries the PLMN ID information of the selected P-GW. After receiving the message, the HSS saves the PLMN ID information of the P-GW selected by the IP-CAN session. When the MME sends a request to create a default bearer to the S-GW, it includes the PLMN ID of the selected P-GW, and informs the S-GW of the PLMN ID of the P-GW selected for the IP-CAN session. In this way, the S-GW can compare the received PLMN ID information of the P-GW with its own PLMN ID information: if they are th...

Embodiment 2

[0067]This embodiment describes when the UE is in a 3GPP access roaming scenario, and the 3GPP core network adopts the EPC architecture. The UE has established attachment in the roaming area. At this time, the UE initiates a new IP-CAN session. After receiving the message, the MME selects a P-GW for the IP-CAN session, and the MME saves the PLMN ID information of the selected P-GW. The MME sends a message to the HSS to notify the HSS to save the PLMN ID of the selected P-GW. After receiving the message, the HSS saves the PLMN ID information of the P-GW selected by the IP-CAN session. When the MME sends a bearer resource allocation request message to the S-GW, it includes the PLMN ID of the selected P-GW, and informs the S-GW of the PLMN ID of the P-GW selected for the IP-CAN session. In this way, the S-GW can compare the received PLMN ID information of the P-GW with its own PLMN ID information: if they are the same, it can be judged that the UE is connected in the Home Routed...

Embodiment 3

[0073] This embodiment describes the scenario where the UE is in a 3GPP access roaming scenario, and the 3GPP core network adopts the EPC architecture. This embodiment describes that the UE is switched from 3GPP access to another 3GPP access, that is, the IP-CAN session service of the UE is switched between 3GPP networks. At this time, the MME has changed, and the New MME will send an authentication request to the Old MME. After receiving the request, the Old MME will send an authentication response to the New MME. Since the Old MME has previously saved the PLMN ID information of the P-GW selected for the IP-CAN session, the response message will include the Old MME for the IP-CAN session. Select the PLMN ID information of the P-GW. New MME saves the PLMN ID information of the P-GW, and when sending a request to create a default bearer to the S-GW, it brings the PLMN ID information of the P-GW and informs the S-GW of the P-GW selected by the IP-CAN session PLMN ID information...

Abstract

The invention provides a method for acquiring a terminal roaming access way. A terminal UE is accessed into a PDN network in 3GPP and initiates IP-CAN session service. The method comprises the following steps: an MME assigns P-GW for IP-CAN session, and preserves the PLMN ID information of the P-GW; the MME sends a loading request message to S-GW, and the preserved PLMN ID information of the P-GW is carried in the message; after receiving the message, the S-GW acquires the terminal roaming access way according to the comparison between the PLMN ID information of the P-GW and the PLMN ID information of the S-GW, and accomplishes the IP-CAN session establishment flow. The method of the invention ensures the loading binding and event reporting function entity resided in a service gateway or an access gateway to acquire the terminal roaming access way.

Description

technical field [0001] The present invention relates to the field of wireless networks, in particular to a method for a bearer binding and event reporting functional entity to acquire a roaming access mode of a terminal. Background technique [0002] The system architecture diagram of the 3GPP evolved packet system (EPS, Evolved Packet System evolved packet system) is as follows figure 1 As shown, the EPS system consists of an evolved UTRAN (E-UTRAN, Evolved Universal Terrestrial Radio Access Network), an MME (Mobility Management Entity), and an S-GW (Serving Gateway) , PDN GW (P-GW, Packet Data Network Gateway, packet data network gateway), HSS (Home Subscriber Server, Home Subscriber Server), 3GPP AAA server (3GPP Authentication Authorization Accounting Server), PCRF (Policy and Charging RulesFunction, strategy and billing rule function) and other supporting nodes. in, [0003] MME is responsible for mobility management, non-access stratum signaling processing, user mob...
