Problems solved by technology

That is to say, in different scenarios of 3GPP access and non-3GPP access, different requirements are put forward for the behavior of P-GW, and different network elements are used when reporting the APN+P-GW identity to HSS / AAA for storage. Execute reporting, which makes the operation process appear chaotic and inconsistent. At present, there is an urgent need for a gateway identification reporting solution that can unify the operation process and simplify operations.

Embodiment 1

[0061] Method Embodiment 1: Attachment / PDN connection establishment process of P-GW identifier storage.

[0062] This embodiment is according to the present invention, the process of the terminal attaching to the EPS core network through the untrustworthy non-3GPP access network; or, after attaching, the process of establishing an additional PDN connection. During the process of establishing the attach / PDN connection, the ePDG sends The HSS / AAA sends a P-GW identity update message, which carries the P-GW identity, and the HSS / AAA stores the P-GW identity, such as image 3 shown. image 3 Given is the non-roaming scene, the roaming scene is the same as image 3 The difference is that: the interaction between the P-GW and the home policy and charging rule function (hPCRF) is transferred through the visited network policy and charging rule function (vPCRF); the ePDG and the home HSS / AAA The interaction is relayed through the AAA Proxy of the visited network. Differences here d...

Embodiment 2

[0082] Method Embodiment 2: PDN connection release / detach process initiated by UE / ePDG / non-3GPP access network whose P-GW identity is deleted.

[0083] This embodiment is according to the present invention. After the terminal attaches to the EPS core network through an untrustworthy non-3GPP access network (one or several additional PDN connections may or may not be established after attachment), the UE or ePDG or non-3GPP access network Network access initiates the process of detachment / PDN connection release. Among them, "PDN connection release" means that under the premise that the UE has multiple PDN connections, one or several of the PDN connections need to be disconnected, but the UE still maintains the remaining PDN connections, so the UE does not detach from the network side. . During the detachment / PDN connection release process, ePDG sends a P-GW identity update message to HSS / AAA, and after receiving the message, HSS / AAA deletes the P-GW identity, for example Fig...

Embodiment 3

[0099] Method Embodiment 3: PDN connection release / resource deactivation process initiated by P-GW / PCRF with P-GW identity deleted.

[0100] This embodiment is according to the present invention, after the terminal is attached to the EPS core network through an untrustworthy non-3GPP access network, one or several additional PDN connections are established, and the PCRF or P-GW initiates the process of resource deactivation / PDN connection release . During the process of resource deactivation / PDN connection release, ePDG sends a P-GW identity update message to HSS / AAA, and after receiving the message, HSS / AAA deletes the P-GW identity, for example Figure 5 shown. Figure 5 Given is the non-roaming scene, the roaming scene is the same as Figure 5 The difference is that: the interaction between P-GW and hPCRF is transferred through the vPCRF of the visited network; the interaction between ePDG and the home HSS / AAA is transferred through the AAA Proxy of the visited network. ...

Abstract

The invention discloses a gateway identifier reporting method. A packet data network gateway (P-GW) identifier is reported to a home subscriber server (HSS) / authentication, authorization and accounting server (AAA) by an evolutionary packet data gateway (ePDG). The invention additionally discloses a gateway identifier reporting system, which comprises a reporting unit used for the ePDG to report the P-GW identifier to the HSS / AAA. By adopting the method and the system disclosed by the invention, the operational process can be unified and the operation can be simplified in different scenes of 3rd generation partnership project (3GPP) access and non-3GPP access.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for reporting gateway identifiers in a communication network. Background technique [0002] The third generation partnership project (3GPP, 3rd Generation Partnership Project) evolved packet system (EPS, Evolved Packet System) such as figure 1 As shown, Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio AccessNetwork), Mobility Management Entity (MME, Mobility Management Entity), Serving Gateway (S-GW, Serving Gateway), packet Data Network Gateway (P-GW or PDN GW, PacketData Network Gateway), Home Subscriber Server (HSS, Home Subscriber Server), 3GPP Authentication, Authorization and Accounting Server (AAA), policy and charging rule function (PCRF, Policy and ChargingRules Function) entities and other supporting nodes. Among them, MME is responsible for mobility management, non-access stratum signaling processing, user ...
