Problems solved by technology

In this kind of application, the mobile terminal acts as a routing and forwarding function. For the service flows sent by different devices in the local network it proxies, there will be a phenomenon that different service flows are matched to the same packet filter, and PCC cannot be performed on the devices in question.

Embodiment 1

[0042] This embodiment provides a method for implementing policy and charging control, such as figure 2 As shown, including the following steps:

[0043] S101. Receive an uplink packet forwarded by a mobile terminal and sent by a device located in the local network proxy of the mobile terminal; the mobile terminal matches the uplink packet with the IP address of the device in the uplink packet. After the TFT packet filter, it is forwarded through the bearer corresponding to the TFT packet filter.

[0044] The uplink message is matched with a TFT packet filter by the mobile terminal according to the IP address of the device, bound to a bearer corresponding to the TFT packet filter, and forwarded to the GW.

[0045] In the embodiment of the present invention, the mobile terminal-side device IP address attribute is added to the TFT packet filter (of course, it can be realized by extending other attributes or adding new attributes), which is used to match the IP address of the device th...

Embodiment 2

[0055] Such as image 3 As shown, it is a schematic diagram of a network for group access of a public mobile terminal according to an embodiment of the present invention. The mobile terminal acts as a proxy for multiple devices (device 1, device 2...) in the local network to interact with the GW through the wireless access network, and the GW can communicate with external networks (headquarters network and Internet) through the IP backbone network For data exchange, the GW can obtain the PCC rules of the devices in the local network from the PCRF, and the PCC rules on the PCRF can also be obtained from the SPR.

[0056] The method for implementing policy and charging control in this embodiment is as follows Figure 4 As shown, including the following steps:

[0057] S301. The GW obtains the network segment address of the local network proxyed by the mobile terminal.

[0058] When the mobile terminal accesses the network, the gateway GW will return the IP address used by the mobile t...

Embodiment 3

[0105] The method for implementing policy and charging control provided in this embodiment is as follows Figure 5 Shown, including:

[0106] S401: The GW receives an uplink packet forwarded by a mobile terminal and sent by a device located in a local network proxy by the mobile terminal.

[0107] After the mobile terminal matches the TFT packet filter corresponding to the IP address of the device in the uplink packet, the uplink packet is forwarded through the bearer corresponding to the TFT packet filter.

[0108] S402: The GW identifies the service type of the uplink packet, and if the QoS parameters in the uplink PCC rule corresponding to the uplink packet meet the parameter requirements of the service type, perform step S403: The uplink PCC rule corresponding to the matched uplink PCC packet filter performs PCC on the device; if the QoS parameter in the uplink PCC rule corresponding to the uplink packet does not meet the parameter requirements of the service type, then step S403...

Abstract

The embodiment of the invention discloses a method, a gateway and a mobile terminal for realizing strategy and charging control. The method comprises the following steps: receiving an uplink message which is forwarded by the mobile terminal and sent by a device in the local network in the mobile terminal agent, and after the uplink message is matched with the TFT packet filter corresponding to the IP address of the device in the uplink message by the mobile terminal, forwarding the uplink massage through a bearer corresponding to the TFT packet filter; and matching a uplink PPC packet filter corresponding to the IP address of the device in the uplink message, and carrying out policy and charging control (PCC) on the uplink message according to a uplink PCC rule corresponding to the uplinkPCC packet filter. By matching the source IP address attributes in the uplink PCC packet with the IP address of the device in the local network transmitting the uplink message, the invention realizesthe purpose of accurate PCC on the device in the local network.

Description

Technical field [0001] The present invention relates to the field of mobile communication technology, in particular to a method, a gateway and a mobile terminal for realizing policy and charging control. Background technique [0002] Mobile communication is undergoing an evolution to an all-IP network. On the one hand, it is necessary to consider end-to-end QoS (Quality of Service) from mobile terminals to GW (Gateway) to provide customers with satisfactory service quality (especially Real-time services such as voice and video); on the other hand, IP networks can provide many types of services (such as multimedia communications, file downloads, web browsing, etc.), and GW is required to be able to identify different service streams and to separately count traffic and duration information. Report to the billing center. In order to solve the above-mentioned related problems based on flow QoS and charging, 3GPP has defined a PCC (Policy and Charging Control, policy and charging con...
