Problems solved by technology

[0012] However, the resource modification request process initiated by the UE of the existing Rel-8PCC cannot support the UE to request to add one or more new packet filters, and the new packet filters must be associated with an existing SDF
[0013] For the resource modification request process initiated by the UE of the existing Rel-8PCC in the related art, it cannot support the problem that the UE requests to add one or more new packet filters and the new packet filter must be associated with an existing SDF , so far no effective solution has been proposed

Embodiment 1

[0049] According to the embodiment of the present invention, there is provided a policy and charging control for implementing the UE to initiate a bearer resource modification request, which is applied to the PCC architecture of Release 8. The UE accesses through E-UTRAN and the S-GW and the P-GW are used GTP protocol.

[0050] image 3 After the UE establishes the IP-CAN session access service, it initiates a resource modification request, requesting to allocate resources for one or more newly added packet filters, and the packet filter is associated with an existing SDF (with one or more existing packet filters) Association), that is, all packet filters belong to an SDF.

[0051] image 3 It is a flowchart of Embodiment 1 of a preferred policy and charging control method according to an embodiment of the present invention. Such as image 3 As shown, the method includes the following steps:

[0052] In step S301, the PCEF receives the resource modification request message, request...

Embodiment 2

[0059] Figure 4 It is a flowchart of the second embodiment of the policy and charging control method according to the embodiment of the present invention.

[0060] Such as Figure 4 Shown:

[0061] Figure 4 According to an embodiment of the present invention, it provides a policy and charging control for implementing the UE to initiate a bearer resource modification request. It is applied to the PCC architecture of Release 8. The UE accesses through E-UTRAN and the S-GW and P-GW are connected Adopt GTP protocol. The method includes the following steps:

[0062] In step S401, the PCEF receives a resource modification request message, requesting to allocate resources for one or more newly added packet filters, and the packet filter is associated with one or more existing packet filters. The message carries the new packet filter and the linked EPSbearer packet filter id. The message can also carry the QoS information requested for the new packet filter, including QCI and GBR. The ...

Embodiment 3

[0069] According to the embodiment of the present invention, there is provided a policy and charging control for implementing the UE to initiate a bearer resource modification request, which is applied to the PCC architecture of Release 8. The UE accesses through E-UTRAN and the S-GW and the P-GW are used PMIPv6 protocol, or UE access through a trusted non-3GPP access network.

[0070] Figure 5 It is a flowchart of the third embodiment of the policy and charging control method according to the embodiment of the present invention. Such as Figure 5 As shown, the method includes the following steps:

[0071] In step S501, the BBERF receives the resource modification request message and requests to allocate resources for one or more newly added packet filters, and the packet filter is associated with one or more existing packet filters. The message carries the new packet filter and the linked EPSbearer packet filter id. The message can also carry the QoS information requested for t...

Abstract

The invention discloses a policy and charging control method as well as policy control and charging rule functional entities. In the policy and charging control method, a first functional entity receives a request message from a second functional entity, wherein the request message carries a first packet filter which requires to allocate resources; the first functional entity updates a rule containing a second packet filter according to the first packet filter, wherein the second packet filter is a packet filter to which the first packet filter is required to be related; and the first functional entity sends the updated rule to the second functional entity. By using the policy and charging control method of the invention, when user equipment initiates a resource modification request, the policy control and charging rule functional entities can relate one or more than one new packet filters added by the user equipment to an existing service data stream.

Description

Technical field [0001] The present invention relates to the field of communication, and in particular to a policy and charging control method and a policy control and charging rule functional entity. Background technique [0002] In the 3rd Generation Partnership Project (3GPP) Phase 7 (Release7) standard system, the policy and charging functions are implemented by the Policy and Charging Control (PCC) architecture . The PCC architecture is a functional framework that can be applied to multiple access technologies. For example, it can be applied to the UMTS Terrestrial Radio Access Network (UMTS) of the Universal Mobile Telecommunications System (UMTS). UTRAN), Global system for Mobile Communication (GSM) / Enhanced Data rates for Global Evolution (EDGE) radio access network, and Interworking Wireless Local Area Network (I-WLAN) Wait. [0003] In order to improve the performance of the 3GPP access system, the 3GPP standards organization further developed the Evolved Packet System ...
