Abstract

The method interconnect broadband wireless access (BWA) network with optical access broadband network (OAN) through any reference point from reference point T, a, ODN, and V inside OAN. Using the disclosed method can solve issue of interconnection between network of world interaction microwave access (WiMAX) and OAN. The invention provides a developing approach for OAN operation manager to develop WiMAX network. The invention puts forward tight coupling mode and loose coupling mode. In the tight coupling mode, building WiMAX network makes the most of line resources laid by original OAN network so as to avoid additional interconnection wiring and lower cost for building WiMAX network. In the loose coupling mode, WiMAX network and OAN network are already built by two operation managers so that interconnection and intercommunication are carried out between two networks in order to share services and application resources on two networks.

Description

The method and system of BRAN and the interconnection of optical fiber accessing to wide band network

Technical field

The present invention relates to communication field, relate in particular to the method and system of a kind of BRAN and optical fiber accessing to wide band network interconnection.

Background technology

FTTH (fiber-to-the-home front yard) technology is a hot spot technology in the present communication field, but because the obstacle of aspects such as cost, technology and demand, this technology is not also promoted on a large scale so far and is developed.Because the development of PON (EPON) technology, FTTH net enter fast-developing period.New equipment, new networking plan are constantly released.

FTTH is a kind of final form of FTTx (Optical Access Network) development, and the formal title of FTTx is optical fiber FITL (Fiber in the loop, a local loop).According to the place, position of ONU (optical network unit), FTTx is divided into FTTH, FTTB (Fiber To The Building) and FTTC several situations such as (Fiber To The Curb).The high bandwidth that FTTx inserts can be carried out the business of Triple Play (transferring voice, data and multimedia video simultaneously) better.FTTx mainly adopts the technology of PON, and the FTTx technology of the comparative maturity of main flow mainly contains two kinds now: EPON (ethernet passive optical network) and GPON (gigabit passive optical network).Wherein EPON is the technology of releasing calendar year 2001, and the GPON standard was passed through by ITU (International Telecommunications Union) in January, 2003.

The main network architecture of FTTx network as shown in Figure 1.The network reference framework of OAN in the FTTx network (optical access network) as shown in Figure 2.

OAN is made up of CPN (local network of users), Access Network (Access Network) and Service Node Function (business function point).Wherein the main network element of the local network of users and Access Network comprises: OLT (light path destination node), ODN (optical distribution network), ONU/ONT, adaption function body AF.In Access Network, AF (adaption function body) is an optional equipment, mainly provides the mutual conversion of ONU/ONT (Optical Network Terminal) interface and UNI (User Network Interface), and AF also can be built among the ONU, and " a " reference point can not wanted like this.AF also can be placed on the mutual conversion that OLT makes OLT interface and SNI (service point interface) afterwards.AF both can regard the functive of CPN as, also can regard the functive of AccessNetwork as.T is the reference point of uni interface, and V is the reference point of SNI interface.OLT provides network interface and is connected to one or more ODN for ODN.ODN provides transmission means for OLT and ONU.ONU provides user side interface for OAN and links to each other with ODN.

User's equipment CPE is connected to AF by uni interface (as: by the DSL circuit), AF is connected message format by uni interface format conversion Cheng Nengyu ONU a interface (as: Ethernet link) form, ONU converts message to the form (as: encapsulation of the encapsulation of EPON, the general-purpose group frame of GPON) that can transmit again on ODN.Convert message the message format of SNI interface (as: Ethernet link) to by OLT at last, carry out the visit of service point again.

The broadband access method that broadband wireless access BWA (Broadband wireless access, broadband wireless access) equipment can be provided convenience for the user.Broadband wireless access equipment based on proprietary protocol is arranged at present, the broadband wireless access equipment based on standard agreement is also arranged.The broadband wireless access equipment of IEEE (IEEE) 802.16 standard definitions is subclass of the series standard of wireless access wide band technology.Comprise WIMAX (global interactive inserting of microwave) equipment in the BWA equipment.

IEEE 802.16 is first broadband wireless access standards, and this standard mainly contains two versions: " 802.16-2004 ", promptly the broadband fixed wireless of 802.16 standards inserts version." 802.16e ", promptly the broadband mobile wireless of 802.16 standards inserts version.Wherein, 802.16-2004 has only defined two kinds of network element: BS (base station) and SS (subscriber station), adopts the interconnection of broadband fixed wireless access technology between BS and SS; 802.16e also only defined two kinds of network elements, BS and MS (mobile subscriber station) adopt broadband mobile wireless access technology interconnection between BS and MS.

WiMAX Forum has defined ASN (access service network) and CSN (connection service network) on 802.16 basis, constituted broadband WiMAX network, with support to fix, nomadic, portable, simple IP moves or move entirely and insert.With 802.16e is example, and the frame of reference schematic diagram of WIMAX network as shown in Figure 3.

In Fig. 3, R1 is the reference point between MS/SS and ASN, and R3 is the reference point between ASN and CSN; T is the reference point between TE and MS/SS in the CPN network.MS can be simple Mobile Terminal (portable terminal), also can articulate TE again below MS.

The WIMAX802.16e mobile network adopts two-layer mobile management framework, adopts 802.16 Security Sublayer PKMv2 (private key management version 2) and DHCP (DHCP) that terminal configuration and controlling links and managerial ability are provided.Moving under the application, WIMAX 802.16e mobile network adopts three layers of mobile management based on MIP (mobile IP) between ASN and CSN.

Can adopt three layers of route technology of IP between ASN Egress node and MS, on eating dishes without rice or wine, support IP CS (IP convergence sub-layer); Also can adopt the double layer network bridging technology between ASN Egress node and MS, as use ethernet bridging, on eating dishes without rice or wine, support ETHCS (Ethernet-Aggregation sublayer).

OAN development now is swift and violent, provides possibility for the user realizes the high bandwidth access.And the wireless access of WiMAX, for the mobility that realizes broadband access and the coverage rate that enlarges the broadband provide condition.In the prior art, also how not utilize existing OAN Internet resources to carry out layouting of WiMAX wireless base station, and the method that how to realize the interconnection of WiMAX network and OAN network.
