Problems solved by technology

The S-GW will have APN information at this time, and the S-GW will still select the PCRF domain according to the APN information, but it does not know that the user used S2c access before the handover, but at this time, the PCRF domain selected according to the APN and the PCRF domain used before the handover occurred The statically configured PCRF domains are different, so there is no guarantee that all messages related to an IP-CAN session will be sent to the same PCRF

Embodiment 1

[0026] This embodiment describes when the UE is in the S2c access non-roaming scenario, and the 3GPP core network adopts the EPC architecture. In the network, DRA adopts Redirection (redirection) mode to manage PCRF. The UE is handed over during the moving process, and is handed over to 3GPP access or trusted non-3GPP S2a access. The flow chart of this embodiment is as follows Image 6 As shown, each step is described as follows:

[0027] Step 601, the S-GW or the trusted non-3GPP access gateway selects a PCRF domain according to the APN, and sends a gateway control session establishment message to the DRA in this domain, with a handover identifier in the message, and the selected PCRF domain may be a PCRF domain 1, or PCRF domain 3. In this example, it is assumed that PCRF domain 1 is selected.

[0028] Step 602, DRA1 inquires locally, does not find the relevant information of the IP-CAN session, and the gateway control session establishment message received has a handover...

Embodiment 2

[0037] This embodiment describes when the UE is in the S2c access non-roaming scenario, and the 3GPP core network adopts the EPC architecture. In the network, the DRA adopts the proxy (relay) mode to manage the PCRF. The UE is handed over during the moving process, and is handed over to 3GPP access or trusted non-3GPP S2a access. The flow chart of this embodiment is as follows Figure 7 As shown, each step is described as follows:

[0038] Step 701, the S-GW or a trusted non-3GPP access gateway selects a PCRF domain according to the APN, and sends a gateway control session establishment message to the DRA in the domain, with a handover identifier in the message, and the selected PCRF domain can be PCRF domain 1 may also be PCRF domain 3. In this example, it is assumed that PCRF domain 1 is selected.

[0039] Step 702, DRA1 inquires locally, does not find the relevant information of the IP-CAN session, and the gateway control session establishment message received has a hand...

Abstract

The present invention provides a method of Diameter route entity relaying messages, including: the Diameter route entity supporting part strategy and accounting rule function domain applied in the access point name, receives a gateway control session establishment information transmitted by the gateway, if carrying with a switching mark, the information is transmitted to the Diameter route entity supporting part strategy and accounting rule function domain applied in the access point name, and the Diameter route entity queries strategies and accounting rule function for distributing the IP communication access network session, finally, the gateway control session establishment information is transmitted to the strategies and the accounting rule function. After the user uses S2c access to switch to 3GPP access or a credible non-3GPP S2a access, the technical solution of the invention realizes that the information corresponding to the IP communication access network session is transmitted to the same strategy and accounting rule function.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for a Diameter routing entity to forward a message. Background technique [0002] 3GPP Evolved Packet System (EPS, Evolved Packet System Evolved Packet System) consists of Evolved UTRAN (E-UTRAN, Evolved Universal Terrestrial Radio Access Network Evolved Terrestrial Universal Radio Access Network), ME (Mobility Management Entity), S-GW (Serving Gateway, Serving Gateway), PDN GW (P-GW, Packet Data Network GateWay, data network gateway), HSS (Home Subscriber Server, HomeSubscriber Server), 3GPP AAA server (3GPP authentication authorization accounting server), PCRF (Policy and Charging Rules Function, policy and charging rule function), and other supporting nodes. Among them, MME is responsible for mobility management, non-access stratum signaling processing, user mobility management context management and other control plane related work; S-GW is an access gateway device connect...
