Technical field

The present invention relates to communication technical field, relate in particular to the optimization wireless network layer and realize the method and system of network interconnection and the interconnecting method of wireless network and cable network.

Background technology

The Optical Access Network of prior art (general designation FTTx) is with the place, position of optical network unit (ONU), be divided into FTTH (Fibre To The Home fiber-to-the-home), Fiber To The Building (FTTB, Fibre ToThe Building) and Fiber To The Curb several situations such as (FTTC, Fibre To The Curb).

Optical Access Network (OAN, Optical Access Network) formal title is FITL (FITL, Fiberin the loop), because the high bandwidth that optical access network inserts can better be carried out the i.e. business of while transferring voice, data and multimedia video of Triple Play.Optical Access Network mainly adopts EPON (PON, Passive Optical Network,) technology, PON is as a kind of broadband access technology of emerging last kilometer of covering, it does not need node device at ODN, only need that a simple optical branching device is installed and get final product, advantage such as therefore have the cable resource of saving, device security height, networking speed is fast, maintenance is simple.Can obtain transfer resource very easily for the building of opening FTTH, and because the high broadband property of FTTH is the effective means of supplementing out economy that solve 3G IP transmission base station.

And main flow comparative maturity technology mainly contains two kinds now: ethernet passive optical network (EPON, Ethernet Passive Optical Network) and gigabit passive optical network (GPON, GigabitPassive Optical Network).The main network architecture of FTTx network has been described the network architecture of optical access network as shown in Figure 1, and its concrete OAN frame of reference as shown in Figure 2.

OAN is made up of the local network of users (CPN), Access Network (Access Network) and business function point (Service Node Function).Wherein the main network element of the local network of users and Access Network comprises: light path destination node (OLT), optical distribution network (ODN), ONU/ (Optical Network Terminal) ONT, adaption function body AF.In Access Network, AF (adaption function body) is an optional equipment, mainly provides the mutual conversion of ONU/ONT 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 service point interface (SNI) afterwards.AF both can regard the functive of CPN as, also can regard the functive of Access Network 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.

Adopt similar structure at the 3G/2G wireless communication system, it comprise Radio Access Network (RadioAccess Network, RAN) and core network (CN, Core Network).Wherein Radio Access Network RAN is used to handle all and wireless function associated, and CN handles that all voice calls are connected with data in the wireless communication system, and the exchange of realization and external network and routing function.CN is from being divided into circuit commutative field (CS, Circuit Switched Domain) and packet-switched domain (PS, Packet Switched Domain) in logic.RAN, CN and travelling carriage (MS, Mobile Station) have constituted whole 3G/2G cordless communication network together, and its system reference framework as shown in Figure 3.

Wherein, base station (BS, Base Station) is called base transceiver station (BTS, Base Transceiver Station) in GSM/GPRS/CDMA/CDMA2000, be called Node B (Node B) in WCDMA/TD-SCDMA; Base station controller BSC is called radio network controller (RNC, Radio Network Controller) in WCDMA; In CDMA2000, Packet Control Function entity (PCF, Packet Control Function), PCF is positioned at BSC and packet data serving node (PDSN, Packet Data Serving Node) between, the Packet data service support is provided, part as Radio Access Network can put together with BSC, also can place separately.

For WCDMA, used the Iu series interfaces among the UTRAN, comprise Iu, Iur and Iub interface, these interfaces are pressed UTRAN interface general protocol model division protocol stack and are made up of corresponding wireless network layer (RNL) and transport network layer (TNL).The Iu interface is the interface that connects UTRAN and CN, is the standard interface of an opening, and its chain of command agreement is RANAP, and user plane protocol is the GTP agreement.The Iur interface is the interface that connects between the RNC, is the distinctive interface of UMTS system, is used for the mobile management to the RAN travelling carriage.When carrying out soft handover between different RNC, all data of travelling carriage all are to pass to candidate RNC by the Iur interface from the RNC that is working.Iur also is open standard interface, and Iur interface control plane agreement is RNSAP, and user plane protocol is Iur FP.Iub interface is the interface that connects NodeB and RNC, and Iub interface also is the standard interface of an opening, and its chain of command agreement is NBAP, and user plane protocol is Iub FP.

Node B is the base station (being radio receiving-transmitting unit) of WCDMA system, comprises radio receiving-transmitting unit and Base-Band Processing parts.By the Iub interface and the RNC interconnection of standard, mainly finish the processing of Uu interface physical layer protocol.Its major function is spread spectrum, modulation, chnnel coding and despreading, demodulation, channel-decoding, also comprises the functions such as mutual conversion of baseband signal and radiofrequency signal.

Described radio network controller (RNC) is used to control the Radio Resource of UTRAN, mainly finishes functions such as connection foundation and disconnection, switching, the merging of grand diversity, RRM control.Specifically comprise: (1) executive system information broadcast and system's access control function; (2) switching and RNC migration mobile management functions such as (Relocation, or reorientation); (3) RRM and controlled function such as grand diversity merging, power control, radio bearer distribution.

Radio interface protocols trestle structure between user equipment (UE) and the UTRAN has comprised various protocols, the different nodes that they are distributed in the Radio Access Network are realized, as shown in Figure 4, wherein, the RRC agreement realizes in UE and RNC, it mainly realizes the management that RRC connects, the management of radio bearer, functions such as paging/broadcasting and mobile management.It is responsible for disposing the parameter information of other protocol entities in the Radio interface protocols stack.Rlc protocol realizes that in UE and RNC it mainly realizes the transfer function of user data, and it provides three kinds of data-transmission modes, is suitable for transmitting the business datum that different QoS requires respectively.The MAC agreement realizes in UE and RNC that usually it is responsible for user data and selects suitable transformat, is responsible for realizing the mapping of logic channel to transmission channel.For some special channel types, the realization of MAC agreement is arranged also among the Node B.The PDCP agreement realizes in UE and RNC, its function comprises: carry out the header suppression and the decompression of IP traffic respectively in transmission and receiving entity, as the combination of TCP/IP and corresponding particular network layer transport layer of RTP/UDP/IP header compression method or upper-layer protocol; Transmitting user data is that the PDCP-SDU that Non-Access Stratum is sent here is forwarded to rlc layer, if support that harmless SRNS shift function is then transmitted PDCP-SDU and corresponding sequence number is multiplexed into same RLC entity with a plurality of different RB.

The function of BMC comprises: the storage of cell broadcast messages; Service traffics monitor and are CBS requirement Radio Resource; The scheduling of BMC message; Send BMC message to UE; Transmit cell broadcast messages etc. to high-rise (NAS).

Because Node B only handles physical layer protocol in the existing protocol stack, in case the adaptive technique that needs the employing resource management to adjudicate, all need in RNC, realize, network must be through RNC to Node B to terminal, Node B is to two stages of terminal, vice versa, thereby cause the long time delay of Iub interface, and reduced the disposal ability of Node B and the statistic multiplexing rate of Iub interface transfer resource; And the retransmission mechanism of the rlc layer between RNC and the UE is under Iub interface exists than the long time delay situation, and throughput can descend; And the exterior ring power control algolithm can not be carried out SIRtarget according to the variation of air interface fast and adjust under the big situation of Iub interface time delay; The while cell load information relies on NodeB at present and periodically reports, and has information delay, and the load information that causes RNC to obtain is not real-time.

This shows, all are inserted high-risely all be placed on protocol architecture among the RNC the incompatibility high speed data transfer, be similar to the technology of self adaptation coordination, FEEDBACK CONTROL in employing after, this kind protocol architecture can not guarantee high speed, efficient, thereby is difficult to adapt to the demand of high speed data transfer.

HFC access network (DOCSIS) is the two-way mutual broadband networks that is based upon on the cable TV coaxial net basis, it has kept traditional analogue transmission mode, make full use of existing cable tv coax resource simultaneously, do not need to lay again distribution network and just can be the user multiple business such as phone, radio and television, video request program, Internet access, video conference, data are provided.Therefore, DOCSIS has low cost, broadband and multi-service characteristic, and it will become the preferred version that solves last 1 kilometer broadband access.DOCSIS is the CableLabs standard to two-way mutual HFC Access Network, and grouping cable (PacketCable) standard is MSO (multi-business operator's) the broadband network standard that is based upon on the basis of DOCSIS.

PacketCable is divided into HFC access network, the local network of users and Managed IP Network (IP network management), based on the PacketCable frame of reference of HFC access network as shown in Figure 5, the main network element of the HFC access network and the local network of users comprises: cable modem local side apparatus (CMTS), HFC transmission network (HFC/Cable Network), cable modem (CM, Cable Modem), multimedia terminal adapter MTA (Multimedia Terminal Adapter omits among the figure) etc.Wherein, CMCI is the reference point of ustomer premises access equipment in the local network of users (CPE) and CM; CMRFI is the reference point between CM and HFC/Cable Network; CMTS-NSI is Ethernet-Aggregation (Ethernet Aggregation) reference point between CMTS and Managed IP Network.

Between MANAGED IP NETWORK and CPE, can only adopt the double layer network bridging technology; Also can adopt three layers of route technology of IP.

The transmission method of a kind of 2G of the prior art or 3G network base station is:

Adopt the transmission technology of E1/T1 as the base station, for example, in WCDMA typical case networking transmission means schematic diagram shown in Figure 6, the Iub interface of WCDMA goes out the E1 networking, the highest only 2Mbps of bandwidth that WCDMA provides for each user, WCDMA R99 is the ATM transmission technology in the Iub transmission, ATM can be carried in the TDM transmission, go up (the E1 transmission rate is 2MHz, and the T1 transmission rate is 1.5MHz) as E1/T1.Usually, the multichannel binding need be carried out to E1/T1 in order to support a large number of users in the base station, promptly adopts IMA (Inverse Multiplexing over ATM) technology.

In the above-mentioned prior art, after the needed transmission bandwidth of data service improves constantly, if operator's transmission continues to use the E1/T1 transmission means, because the transmission rate of E1/T1 transmission means is lower, link load between BS and the base station controller can be bigger, can't satisfy the rate requirement of high-speed data service, can't give security for the QoS of high-speed data service.Simultaneously,, expensive low income will be caused, and the level of profitability of operator can be had a strong impact on because data service is low-cost.

Therefore, the transmission problem of wireless network will be the problem that operator presses for solution, no matter be the transmission network of setting up oneself, still seek other cheap substitute technologies, all will be the choice that operator directly faces.
