Description
Technical field
The present invention relates to telecommunications basic network, broadband access network field and fixing mobile integration technology field.
Background technology
Existing 3G technology provides solution for the aspect that is used to satisfy user's high speed data transmission service demand, and a lot of areas have obtained application in the world, but because the restriction of frequency spectrum is difficult to arrive desirable theoretical speed under the situation that many people share.And at present, have benefited from the development of technology in recent years based on wireless fixed network broadband inserting service, as the practical application of the ADSL access technology of its representative from 512Kbps to 2Mbps, 8Mbps, 12Mbps.With respect to the mobile wireless access technology, the lifting that line access velocity arranged is far away faster than the lifting of wireless access rate, so can better provide miscellaneous service on cable broadband.But in the at present general broadband application, do not carry out the mechanism of traffic differentiation, cause operator, can't guarantee professional QoS providing some high-grade when professional according to business.For example in fixing mobile fused business, for the quality of the mobile service that guarantees on cable broadband, to provide, and be different from other business in the existing broadband access, guarantee that certain broadband access ability and Qos guarantee must for fixing mobile fused business.Fixing mobile fused business can provide better better service for the user, can improve the competitiveness of operator greatly, realizes operator and user " doulbe-sides' victory ".
In fixing mobile fused business, the user uses hand-held mobile bimodulus/single-mode terminal to adopt the WLAN technology, by short-distance wireless mode access band metropolitan area network, utilize existing ripe mobile core network realize the subscription authentication authentication, such as the business of voice-and-data etc., the whole network roaming etc., this will be one preferably the broadband move the solution of fusion.
Realize carrying and the service operation of mobile service on broadband network, need existing broadband network to support cable business (as common PC) and dual-mode terminal service traffics route and QoS to distinguish mechanism.
Pass through ipsec tunnel in UMA (the unauthorized mobile access) scheme at present, between terminal and UNC (UMA network controller) equipment, set up the secure communication path of point-to-point, ipsec tunnel provides safe, virtual IP network for GSM/GPRS signaling and the bearer service that transmits between terminal and the UNC, thereby realizes mobile dual-mode terminal and cable business flow route and QoS differentiation.But under this mode, the terminal processes IP stack is too complicated, and treatment effeciency is low, terminal industry threshold height, and obtainable terminal is few on market, does not form optimum terminal industrial chain.
Existing broadband network operator adopts the monthly payment mode to charge mostly, still the not charging of supporting business and application, main cause be go back the neither one maturation on the present broadband network, clear and definite architecture realizes different business flow route and QoS identification and distinguishes mechanism.Simultaneously, existing UMA access scheme is owing to need dual-mode terminal VPN (VPN) client, to realize flow route end to end, thereby be implemented in dual-mode terminal and common PC online flow route and QoS differentiation on the common broadband access network, but this scheme is very high to the specification requirement of terminal, has limited the development of terminal industrial chain.
Therefore, need a kind of new technical scheme to solve above-mentioned the problems of the prior art.
Summary of the invention
In order to address the above problem, the present invention has designed a kind of technical scheme that inserts fixed service (computer etc.) and mobile service (mobile phone etc.) simultaneously and can distinguish these two kinds of business in broadband access network (WLAN) environment.
According to a first aspect of the invention, provide a kind of method that is used on broadband access network distinguishing at least two kinds of service traffics, may further comprise the steps: in described at least two kinds of service traffics each provides a service traffics identifier; At access point, different service traffics identifiers is associated with different Virtual Path Identifier; And come service traffics are carried out route according to described association.
An embodiment according to a first aspect of the invention, wherein said at least two kinds of service traffics can comprise mobile service flow and fixed service flow etc.
Another embodiment according to a first aspect of the invention, described service traffics identifier can be SSID (service set identifiers) etc.
Another embodiment according to a first aspect of the invention, described Virtual Path Identifier can comprise permanent virtual link identifier and vlan identifier etc.
According to a second aspect of the invention, a kind of system that is used for distinguishing at least two kinds of service traffics on broadband access network is provided, wherein, in described system, give each distribution in described at least two kinds of service traffics a service traffics identifier, this system comprises: at least one terminal is used to produce described service traffics; Access point, it is coupled to described at least one terminal and is used for different service traffics identifiers is associated with different Virtual Path Identifier; And switch, it is coupled to described access point and is used for coming service traffics are carried out route according to described association.
An embodiment according to a second aspect of the invention, described at least two kinds of service traffics comprise mobile service flow and fixed service flow etc.
Another embodiment according to a second aspect of the invention, described service traffics identifier can be SSID etc.
Another embodiment according to a second aspect of the invention, described Virtual Path Identifier comprise at least a in permanent virtual link (PVC) identifier and the vlan identifier.
According to the present invention, can distinguish service traffics according to certain standard, for example can distinguish fixed service and mobile service.For the person of ordinary skill of the art, the notion of fixed service and mobile service is clearly.In this manual, fixed service refers to the business that inserts this class of Internet by computer, and mobile service refers to the existing business that communicates by mobile phone, it for example can be speech business, but also can be the business of networking that provides by mobile operator, such as WAP business etc.
Owing to only need the identifier of service traffics and the sign of Virtual Channel are carried out related, therefore, the present invention implements fairly simple, and, do not need existing equipment is carried out big change.
