Description

A kind of system and method for realizing end-to-end service of heterogeneous network QoS control

Technical field

The present invention relates to communication technical field, relate in particular to a kind of system and method for realizing end-to-end service of heterogeneous network QoS control.

Background technology

Fast development along with the communication technology, various communication system networks such as UMTS (network of universal mobile communication system), IEEE 802.11WLAN (WLAN), IEEE 802.16WMAN (wireless MAN), GPRS/EDGE (GPRS/enhanced data rates for gsm evolution technology), TD-SCDMA (TDS-CDMA system), CDMA2000 (CDMA 2000 system), WCDMA (broadband CDMA system), Bluetooth (Bluetooth technology) etc. emerges in an endless stream, but various communication system networks are each have their own characteristic and advantage aspect the guarantee of professional ability and QoS of customer, is difficult to occur a kind of grid has absolute predominance with respect to the other system network situation.Therefore, multiple different communication systems access network has promptly constituted heterogeneous network, and wherein the network coexisted cooperation of plurality of communication systems provide colourful service quality (the Quality of Service that has for the user, QoS) business experience of Bao Zhanging will be foreseeable next generation network (Next Generation Network, NGN) one of a system big key character.

And NGN adopts IP (Internet Protocol, Internet protocol) technology to become the common recognition of industry as the group technology of bearer network, and this is just to providing the multiple business with QoS guarantee to have higher requirement on IP network.For this reason, introduced the notion of resource and admission control in NGN: by carrying out resource and admission control, upwards transmit the detail of network to the operation layer shielding, supporting business control is separated with transmitting function; The resource behaviour in service that transmits network is obtained in perception downwards, guarantees that business holds water to use the resource that transmits network.Based on this, ITU (International Telecommunication Union, International Telecommunications Union) has proposed the QoS problem that RACF (Resource and Admission Control Function, resource accommodating control function) solves the NGN bearer network.

Wherein, the systemic-function framework that comprises described RACF as shown in Figure 1, it comprises following essential functional entities: SCF (business control function body), PD-FE (policy deciding functional entity), TRC-FE (flow resource control function entity), PE-FE (policy execution functional entity) and TRE-FE (transmit resource and carry out functional entity); Wherein,

Described SCF mainly obtains the qos parameter of request access service, and sends it among the PD-FE; The qos parameter that described PD-FE mainly utilizes described SCF to send to get off and from NACF (NetworkAttachment Control Functions, the network attachment controlled function) the transfer resource CAMEL-Subscription-Information that obtains is made preliminary QoS resource decision, then by with TRC-FE alternately to obtain the resource information of current network, and make final decision, again this decision-making is handed down to PE-FE; Described TRC-FE is mainly used in the resource in the supervisory network and collects relevant information, and makes according to concrete resource situation when the PD-FE request resource and replying; The resource decision that described PE-FE is used for issuing according to described PD-FE carries out policy control, comprises gate control, allocated bandwidth, assignment of traffic and mark, traffic shaping, two layers and three layers of concrete operations such as QoS mapping, collection and report resource use information; Described TRE-FE is mainly used under TRC-FE instructs and carries out two layers of strategy execution;

And at present, the mode that realizes resource and admission control by above-mentioned RACF function structure mainly as shown in Figure 2, wherein:

In 201, CPE sends service request to SCF and uses specific service with request, and this service request can comprise or not comprise the qos requirement parameter of any clear and definite service;

In 202, when comprising clear and definite service QoS parameter in the described service request, described SCF directly extracts the qos parameter of the service of asking; Otherwise SCF derives qos parameter (for example bandwidth); Send the resource reservation request that includes clear and definite qos requirement parameter to RACF then, with the mandate and the reservation of request QoS resource;

In 203, described RACF carries out according to policing rule and authorizes and allow control, and clauses and subclauses are subscribed in the transmission that resource allows decision to be stored among the NACF.

Though the mode of above-mentioned RACF function structure and the control of realization resource and admission thereof has embodied the thought of service driving and policy control, provides beneficial reference for control and transmission are separated and reasonably use Internet resources for business.But, the inventor finds after scrutinizing such scheme, there is also tangible deficiency: promptly, because heterogeneous network provides the changeable and complicated of the difference of QoS mechanism and network environment, can not ensure that business also can satisfy business demand in its whole service process if only in access procedure, ensure service resources, therefore in heterogeneous network environment, the QoS of teleservice is protected, also can't makes the user obtain higher professional satisfaction.
