specific Embodiment 1

[0124] Specific embodiment one, as appended Figure 6 As shown, the specific process of establishing a LIPA or SIPTO packet data network (PDN) connection is as follows:

[0125] Step 601: The UE sends an attach PDN connection establishment message to a Mobility Management Entity (MME), and the MME detects and determines that the attach PDN connection establishment message belongs to a LIPA or SPTO connection establishment request.

[0126] Step 602: The MME selects the UE's LGW as the PDNGW corresponding to the LIPA Access Point Name (APN). After the MME initiates a session establishment process to the SGW, the SGW initiates a session establishment request to the LGW.

[0127] In the prior art, after the LGW receives the session establishment request from the SGW, it allocates the user plane tunnel address and port number used to establish the connection between the LGW and the H(e)NB, and carries them back to the SGW in a response message, and the SGW sends the response messa...

specific Embodiment 2

[0138] Embodiment 2: The existing architecture does not support dynamic PCC, and when the UE initiates a LIPA or SIPTO bearer establishment request message, the LGW returns a rejection message. In this specific embodiment, after the above PCC architecture is adopted in the local network, the UE supports dynamic PCC, and different QoS bearers can also be established for different services initiated by the UE, as shown in the attached Figure 7 As shown, the specific process of establishing LIPA or SIPTO bearer for UE is as follows:

[0139] Step 701: After receiving the bearer establishment request from the UE, the SGW sends a request message for establishing a new bearer to the LGW.

[0140] Step 702: The LGW sends a PCC allocation request message to the PAMGW through the first interface of the PAMGW to establish a new IP Connectivity Access Network (IPConnectivityAccessNetwork, IP-CAN) bearer. The PCC allocation request carries the requested PCC policy information, and the re...

specific Embodiment 3

[0148] Embodiment 3: In the existing R10 architecture, the local network does not support the modification process of the established LIPA or SIPTO bearer. If the UE initiates a bearer modification request, the LGW will reject the request. In this specific embodiment, after the above-mentioned PCC architecture is adopted in the local network, the UE supports dynamic PCC, which can realize the bearer modification process of different QoS, as shown in the attached Figure 8 As shown, the specific process is as follows:

[0149] Step 801: After receiving the bearer modification request message from the UE, the SGW sends a bearer modification request message to modify the established bearer to the LGW.

[0150] Step 802: The LGW sends a PCC allocation request message to the PAMGW through the first interface of the PAMGW, requesting to modify the established IP-CAN bearer. The PCC allocation request message carries the PCC policy information requested to be modified, and the PCC po...

Abstract

Disclosed are a communication system, device, and method, for implementing communication between a local gateway (LGW) and a policy and charging rule function (PCRF) in a local network, so as to implement dynamic policy control and charging (PCC) allocation based on the system, bear a dynamic allocation PCC policy for requested local IP access (LIPA) or selected IP traffic offload (SIPTO) of a user terminal (UE), and meet different service requirements. The system comprises an LGW and a PCRF, and further comprises a policy aggregation management gateway (PAMGW). The PAMGW is used to receive a message of the LGW through a first interface connected to the LGW, send the message to the PCRF through at least one second interface connected to the PCRF, receive a message of the PCRF through the second interface, and send the message to the LGW through the first interface. Further disclosed is a PCC management system and method.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a communication system, device and method. Background technique [0002] In a local network deployment scenario, a user terminal (UE) can access a local network associated with the home base station through a home base station, and this technology is called local IP access (Local IP Access, LIPA). Local networks include home networks, corporate networks, and more. The UE can also directly access the Internet through the home base station system, and this technology is called Selected IP Traffic Offload (SIPTO). [0003] In the third generation mobile communication standardization organization (3GPP) R10 stage, the LIPA technology that UE accesses the local network through the home base station is realized. After the UE accesses the home base station, the data directly accesses the local network through the local gateway (LocalGateway, LGW). without going throu...
