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-8 PCC in the related art, it cannot support the UE to request to add one or more new packet filters and the new packet filter must be associated with an existing SDF problem, no effective solution has yet been proposed

Embodiment 1

[0049] According to the embodiment of the present invention, a policy and charging control is provided to realize UE-initiated bearer resource modification request, which is applied in the PCC architecture of Release 8, UE accesses through E-UTRAN and S-GW and P-GW adopt GTP protocol.

[0050] image 3 After the UE establishes an IP-CAN session to access the 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 the existing SDF (with one or more existing packet filters) Association), that is, all packet filters belong to one SDF.

[0060] Such as Figure 4 Shown:

[0061] Figure 4According to the embodiment of the present invention, a policy and charging control is provided to realize UE-initiated bearer resource modification request, which is applied in the PCC architecture of Release 8, and the UE accesses through E-UTRAN and the communication between S-GW and P-GW Adopt GTP protocol. The method includes the following steps:

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

Embodiment 3

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

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, in particular, to a policy charging control method and a policy control and charging rule functional entity. Background technique [0002] In the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) Phase 7 (Release7) standard system, the policy and charging functions are implemented by the policy and charging control (Policy and Charging Control, referred to as 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 Terrestrial Radio Access Network, referred to as UMTS) of the Universal Mobile Telecommunications System (UMTS for short). UTRAN), Global system for Mobile Communication (GSM for short) / GSM Data Enhanced Evolution (Enhanced Data rates for Global Evolution, EDGE for short) radio access network, an...
