Принадлежит:

The invention discloses a method of policy and charging control (PCC) conversation binding in a network address translation (NAT) deployment environment. The method includes the following steps: a policy and charging rule function (PCRF) receives a first address of user equipment (UE) reported by a policy and charging enforcement function (PCEF) and a second address reported by an application function (AF); conversation between the PCEF and the PCRF and conversation between the AF and the PCRF are bound through judging whether the first address and the second address are the same or not; when the first address and the second address are not the same, an address mapping translation relation of the UE established by NAT equipment is obtained; according to the second address and a mapping relation of the address mapping translation relation, a third address corresponding to the second address is inquired; and the first address and the third address are compared to judge whether to be the same ...

The invention discloses a method for guaranteeing quality of an end-to-end session service. The method comprises: A. a policy and charging rules function (PCRF) obtains user identifications of each side of session service, wherein the identifications are reported by an application function (AF); B. according to the user identifications, user subscription information which is stored in a subscription profile repository (SPR) is obtained; C. on the base of obtained user subscription information of each side, a decision of quality of service (QoS) rules of an end-to-end session is made. The scheme solves the problems that in the prior art, due to the fact that QoS parameters between the session sides are different, effective end-to-end load bearing cannot be built and the like, and the technical effect is good. In addition, the invention further discloses the PCRF and the AF.

A compensation method for self-adaption reactive power includes the steps that 1, collecting power network voltage and current signals, performing filtering processing on the power network voltage and current signals through a band-pass filter and eliminating effects on waveform phase and amplitude due to frequency change; 2, voltage signals, after A/D (alternating/direct) conversion, output through the band-pass filter and synchronous reference signals being input into a controller; 3, the controller calculating the collected bus voltage data to obtain an accurate current compensation value; and 4, performing signal adding and subtracting on the real-time adjusted reference voltage (U ref) and feedback bus voltage measuring value (U meas) to obtain a control deviation value and correspondingly adjustment outputting after PID (Proportion Integration Differentiation)control. The compensation is fast in response speed and high in calculating accuracy.

Quality of service (QoS) business execution method in multi-network cooperation and advanced function (AF), policy and charging rules function (PCRF)

Номер: CN103139849A
Автор: Gan Liang, Zhang Wanxin, Yin Yaoyao
Принадлежит:

The invention discloses a quality of service (QoS) business execution method in multi-network cooperation. The QoS business execution method in the multi-network cooperation comprises the following steps: A, acquiring information whether carrying business flows can normally transmit or not in access networks and QoS rules of the business flows; and B, seizing and releasing carried resources of the business flows according to the information whether the carrying business flows can normally transmit or not in the access networks and the QoS rules of the business flows. The QoS business execution method in the multi-network cooperation is capable of ensuring QoS execution of the businesses with high priority, and has good technical effect. In addition, the invention further discloses an advanced function (AF), a policy and charging rules function (PCRF), and access network fringe nodes.
