詞語解釋
PCRF（Policy and Charging Rules Function）是一種支持3GPP的策略和計(jì)費(fèi)規(guī)則功能，它為網(wǎng)絡(luò)提供了計(jì)費(fèi)策略，以及管理網(wǎng)絡(luò)控制和計(jì)費(fèi)的功能。 PCRF的主要功能是在網(wǎng)絡(luò)上實(shí)施策略和計(jì)費(fèi)規(guī)則，以支持用戶的計(jì)費(fèi)和服務(wù)。它能夠自動(dòng)識(shí)別用戶的服務(wù)請(qǐng)求，并在網(wǎng)絡(luò)上實(shí)施相應(yīng)的策略和計(jì)費(fèi)規(guī)則，以滿足用戶的服務(wù)要求。 PCRF技術(shù)可以實(shí)現(xiàn)用戶的計(jì)費(fèi)和服務(wù)管理，它可以支持多種計(jì)費(fèi)模式，包括按用量計(jì)費(fèi)、按時(shí)間計(jì)費(fèi)和按流量計(jì)費(fèi)等。PCRF可以根據(jù)用戶的服務(wù)請(qǐng)求，自動(dòng)選擇合適的計(jì)費(fèi)模式，并實(shí)施相應(yīng)的策略和計(jì)費(fèi)規(guī)則，以滿足用戶的服務(wù)要求。 PCRF還可以實(shí)現(xiàn)網(wǎng)絡(luò)控制，可以根據(jù)用戶的服務(wù)請(qǐng)求，自動(dòng)選擇合適的網(wǎng)絡(luò)控制策略，以實(shí)現(xiàn)有效的網(wǎng)絡(luò)管理。它可以支持多種網(wǎng)絡(luò)控制策略，包括流量控制、QoS控制、安全控制等，以確保網(wǎng)絡(luò)的穩(wěn)定性和安全性。 PCRF技術(shù)可以實(shí)現(xiàn)網(wǎng)絡(luò)的自動(dòng)化管理，可以有效地提高網(wǎng)絡(luò)的運(yùn)行效率，提高用戶的服務(wù)質(zhì)量，并降低網(wǎng)絡(luò)運(yùn)營成本。PCRF技術(shù)已經(jīng)成為網(wǎng)絡(luò)計(jì)費(fèi)和服務(wù)管理的核心技術(shù)，在網(wǎng)絡(luò)計(jì)費(fèi)和服務(wù)管理中發(fā)揮著重要作用。 PCRF（策略和計(jì)費(fèi)規(guī)則功能）是業(yè)務(wù)數(shù)據(jù)流和IP承載資源的策略和計(jì)費(fèi)控制判決單元 Policy charging and rules function (PCRF) is the node designated in real-time to determine policy rules in a multimedia network.[1] As a policy tool, the PCRF plays a central role in next-generation networks. Unlike earlier policy engines that were added on to an existing network to enforce policy, the PCRF is a software component that operates at the network core and efficiently accesses subscriber databases and other specialized functions, such as a charging systems, in a scalable, reliable, and centralized manner. The PCRF as the part of the network architecture that aggregates information to and from the network, operational support systems, and other sources (such as portals) in real time, supporting the creation of rules and then automatically making intelligent policy decisions for each subscriber active on the network. Such a network might offer multiple services, quality of service (QoS) levels, and charging rules.
