In World Interoperability for Microwave Access, WiMax (WiMAX) network of 802.16 definition, RAN is called as access business network (ASN, Access Service Network), CN is called as and connects business network (CSN, Connectivity Service Network), its system reference framework as shown in Figure 2.Wherein, BS can be directly inserts CSN by access service gateway (ASN-GW), and BS can be placed on the same entity physically with ASN-GW, also can distinguish placement separately; Perhaps, BS also can be as be divided into two network elements of BTS and BSC at the 3G/2G network.

The above network all belongs to cordless communication network, below the number spider lines is done a brief introduction.

The DSL network architecture is just developed to enabling the type framework based on Ethernet-Aggregation with the IP QoS that is connected (Ethernet Aggregation and connectivity) by PPP over ATM, and under this background, the generalized reference framework of DSL network as shown in Figure 3.

Referring to Fig. 3, T is the reference point between middle terminal equipment (TE, Terminal Equipment) of user resident network (CPN, Customer Premises Network) and DSL modulator-demodulator (DSL Modem is called for short Modem); U is DSL modulator-demodulator (Modem, MOdulator﹠amp; DEModulator) and the reference point between access point Digital Subscriber Line Access Multiplexer (DSLAM, DSL AccessMultiplexer); In Access Network (Access Network), it between DSLAM and DSL network edge node aggregation networks (Aggregation Network), wherein, the DSL network edge node is BAS Broadband Access Server (BRAS, Broadband Remote AccessServer) or wideband network gateway (BNG) or edge router (ER), be that example is represented with BRAS among Fig. 3; V is in the Access Network, the Ethernet-Aggregation between DSLAM and BRAS (EthernetAggregation) reference point; A10 is Access Network and service provider (SP, Service Provider) reference point between, this reference point both can connect application service provider (ASP, ApplicationService Provider) to the Internet Service Provider (NSP that has Access Network, Network ServiceProvider), or under the roaming sight, connect NSP to visit ground Access Network.Adopt the interconnection of DSL access technology between CPN network and Access Network.

Be example only below, in conjunction with the accompanying drawings, specify the process of realization with the PS territory of WCDMA.

Interconnect scheme one:

Shown in Fig. 4 a, Fig. 4 b and Fig. 4 c, use three kinds of embodiment of the present invention, the characteristics of these three kinds of execution modes are: BS in the cordless communication network or WA1 interconnect by DSL Modem and the reference point U that has now in the general DSL network, cordless communication network WA2 or CN and DSL network edge node are in reference point A10 interconnection, thus the interconnection of realization cordless communication network and DSL network.The DSL network edge node can be for BRAS, wideband network gateway (BNG) or edge router (ER), and is easy in order to describe, and only is that example describes with BRAS in the embodiment of the invention, but is not limited to BRAS.The advantage of such interconnecting method is, make the radio communication access network, the resource of as far as possible utilizing former DSL network to lay as the construction of the access network of 3G/2G/WiMAXW, thus the construction cost of radio communication access network reduced, thereby such interconnection belongs to the close coupling scheme.The difference of above-mentioned three kinds of execution modes is, only has WA2 in Fig. 4 a illustrated embodiment, only has WA1 in Fig. 4 b illustrated embodiment, not only has WA1 but also have WA2 in Fig. 4 c illustrated embodiment.

Referring to Fig. 4 a, 4b, 4c, UE at first sets up Radio Resource control (RRC) by the chain of command protocol stack and connects when data communication, begin to carry out the foundation of RAB (RAB) after consulting with core net, the process of setting up of RAB is accompanied by the foundation of user plane radio bearers (RB).After RAB set up successfully, the user just can transmit data by the user plane bearer of having set up.The compression and decompression function of packet data polymerized agreement (PDCP) can be enabled, and also can not enable.Signaling set up flow process be UE be connected with RRC between the UMTS Terrestrial radio access network (UTRAN) set up successfully after, UE sets up by RNC and is connected with the signaling of CN, also cry " Non-Access Stratum (NAS) signaling is set up flow process ", the Signalling exchange NAS information that is used for UE and CN is as authentication, service request, connection foundation etc.Be example to have enabled the compression and decompression function below, specify the transmission course of user's face and chain of command data.

Wherein, the wireless network layer of Uu interface (RNL, Radio network layer) comprises PDCP, Radio Link control (RLC) and medium access control (MAC) at user's face, comprises RRC, RLC and MAC at chain of command.

Referring to Fig. 4 a, be used for the reference point T interconnection of the base station BS and the DSL network of wireless access and control, management, the data in the cordless communication network are had access to spider lines by DSL Modem; WA2 is set, this WA2 is interconnected by reference point A10 and BRAS, and the data in this DSL network are inserted core net.Thereby realize the interconnection of cable network and wireless network.In this interconnection mode, network element BS can separate with DSL Modem or be integrated, and network element BRAS also can logically separate with WA2 or be integrated.The what is called separation is meant that two network elements are independent separately, and what is called is integrated to be meant that both or many persons are integrated into a network element, and the following similar content of this paper together.

For Fig. 4 a, there are three kinds of implementation patterns again, be respectively:

Pattern (1): WA2 is equivalent to the function of RNC, i.e. WA2=RNC;

Pattern (2): WA2 is equivalent to the function of RNC and SGSN, i.e. WA2=RNC+SGSN;

Pattern (3): WA2 is equivalent to the function of RNC, SGSN and GGSN, i.e. WA2=RNC+SGSN+GGSN.

Angle from protocol stack describes respectively above-mentioned three kinds of patterns below.

Referring to Fig. 5 and Fig. 6, it is respectively at the user's face of the pattern (1) in Fig. 4 a illustrated embodiment and the protocol stack structure schematic diagram of chain of command.Based on this protocol stack structure:

Issue wireless network layer (RNL) after being packaged into packet for the application layer data of up user face data: UE, this packet can be User IP packet or ppp protocol bag.RNL compresses this packet header, issue the wireless frequency layer (RFL of physical layer behind the header of increase agreement regulation such as the RLC/MAC header, Radio Frequency Layer), RFL carries out operation such as coded modulation back and sends to UTRAN by the Uu interface to the packet that receives.Among the UTRAN RFL of Node B receive behind the packet this packet encapsulation gone into Frame Protocol (FP FramingProtocol) in the frame, adds the IP head promptly after IP handles with the FP frame, with the IP bag after handling by [the ub interface mails to WA2.To be designated as the FP/IP frame by the IP bag that IP head and FP frame (being IP bag payload) constitute at this, the following similar content of this paper together.

Because the Iub interface Frame Protocol FP/IP frame between Node B and WA2 directly is carried on the DSL network.For example can adopt two layers of bridging technology between Node B and WA2, as ethernet bridging, realize transmission, this moment, DSL Modem and DSLAM were all two layers of network element; Perhaps, adopt three layers of route technology between Node B and WA2, as three layers of route of IP, realize transmission, DSL Modem and DSLAM are all three-layer network unit and realize transmission at this moment.At protocol stack shown in Figure 5, the specific implementation process is:

Node B is divided into Ethernet (ETH) frame with the FP/IP frame, sends to DSL Modem at ethernet physical layer PHY through wired cable; The Ethernet PHY of DSL Modem is converted to the ETH frame with the data that receive, and does the DSL physical frame that the DSL modulation treatment is converted to the twisted-pair feeder transmission that is fit in the cable network then, is sent to DSLAM through twisted-pair feeder; The DSL physical frame of DSLAM carries out the processing of DSL rectification and obtains the ETH frame, and the ethernet physical layer PHY that the ETH frame is carried between DSLAM and BRAS is sent to BRAS again; BRAS Ethernet PHY is converted to the ETH frame once more with the data that receive, the ETH frame is done the ethernet mac processing obtain the IP bag, this IP bag is data link layer (LNK again, Data Link Layer) encapsulation, afterwards, the physical layer PHY of Data-carrying between BRAS and WA2 after BRAS will encapsulate again sends to WA2 and does further processing.

Because this moment, WA2 was equivalent to the function of RNC, therefore the processing of itself and existing RNC user's face is identical, be specially: WA2 receives data by PHY, obtain the FP/IP frame after the data that receive are done the LNK decapsulation, this FP/IP frame is converted to the FP frame, because the Iub interface Frame Protocol FP/IP frame between NodeB and WA2 directly is carried on the DSL network, therefore, can regard WA2 as and directly obtain the FP/IP frame from Iub interface this moment, with the packet that obtains after this FP/IP frame decapsulation among the RNL, afterwards, WA2 does the transport network layer of Iu interface and wireless network layer with this packet and handles the back and send to network element among the CN by GTP tunnel.The processing of the transport network layer of described Iu interface comprises the processing of GTP user's face (GTP-U), UDP, IP, LNK, PHY layer, and the wireless network layer of described Iu interface is an Iu UP protocol processes, is used to transmit the user data relevant with RAB.

At CN, SGSN does the transport network layer and the wireless network layer of Iu interface and handles, and will receive data from GTP tunnel and send to GGSN with GTP tunnel through gn interface again.GGSN is exactly User IP packet or the ppp protocol bag of UE from the data that the GTP tunnel of gn interface receives, and GGSN issues external network with the form of User IP packet or ppp protocol bag by the Gi interface again.That is to say that at this moment, the processing procedure and the existing processing procedure of CN net are identical.

Similarly, UE receives the packet of being issued this UE by core network by opposite process.

For up chain of command data: the UE side is with signaling message, signaling message as GMM, SM, SMS message or rrc layer, be packaged into packet at RNL, increase the RFL that issues physical layer behind the header of agreement regulation such as the RLC/MAC header by RNL, RFL carries out operation such as coded modulation and then sends to UTRAN by the Uu interface to the packet that receives.The RFL of Node B receives behind the packet in the Iub interface wireless network layer frame that this data envelope packed in the UTRAN, as is encapsulated as the FP frame, and by the Iub interface transport network layer, as IP/ETH/PHY, WA2 is mail in carrying.The IP layer of the wireless network layer of the Iub interface between Node B and WA2 and transport network layer or signaling bear (Signaling Bearer) layer directly is carried on the DSL network.The IP layer is at FP, and Signaling Bearer is at NBAP, below similar content with.Described wireless network layer comprises FP or NodeB application protocol (NBAP, NodeBApplication Protocol, the NBAP frame exists only between Node B and the RNC), described signaling bear layer comprises Simple Control Transmission Protocol (SCTP, Simple Control TransmissionProtocol) layer and IP layer.For example between Node B and WA2, can adopt two layers of bridging technology,, realize that transmission DSL Modem this moment and DSLAM are all two layers of network element as ethernet bridging; Perhaps, adopt three layers of route technology between Node B and WA2, as three layers of route of IP, realize transmission, DSL Modem and DSLAM are all three-layer network unit and realize transmission at this moment.

At protocol stack shown in Figure 6, the specific implementation process is:

Node B is divided into the ETH frame with FP/IP frame or NBAP/SCTP/IP frame (the IP bag that obtains) after NBAP, SCTP and IP processing, send to DSL Modem at ethernet physical layer PHY through wired cable; The Ethernet PHY of DSL Modem is converted to the ETH frame with the data that receive, and does the DSL physical frame that the DSL modulation treatment is converted to the twisted-pair feeder transmission that is fit in the cable network then, is sent to DSLAM through twisted-pair feeder; The DSL physical frame of DSLAM carries out the processing of DSL rectification and obtains the ETH frame, and the ethernet physical layer PHY that the ETH frame is carried between DSLAM and BRAS is sent to BRAS again; BRAS Ethernet PHY is converted to the ETH frame once more with the data that receive, the ETH frame is done the ethernet mac processing obtain the IP bag, this IP bag is done the LNK encapsulation again, and afterwards, the physical layer PHY of Data-carrying between BRAS and WA2 after BRAS will encapsulate again sends to WA2 and does further processing.

Because this moment, WA2 was equivalent to the function of RNC, therefore the processing of itself and existing RNC chain of command is identical, be specially: WA2 receives data by PHY, obtains FP/IP frame or signaling bear layer Signaling Bearer data after the data that receive are done the LNK decapsulation.For the FP/IP frame, do except that after the processing of IP head and obtain the FP frame, be for the signaling bear layer data and obtain the NBAP frame after SCTP and IP handle, because Iub interface Frame Protocol FP/IP frame or NBAP between Node B and WA2 directly are carried on the DSL network, therefore, WA2 be can regard as this moment and FP/IP frame or NBAP frame directly obtained from Iub interface.If WA2 receives the NBAP frame, then this NBAP frame is carried out respective handling; If WA2 receives the FP/IP frame, obtain the FP frame after then this FP/IP frame being removed the IP head, and to obtaining the packet among the RNL after this FP frame decapsulation, afterwards, WA2 does this packet the network element that sends to after the transport network layer of Iu interface and wireless network layer are handled among the CN.The processing of the transport network layer of described Iu interface comprises the processing of SCCP, Signaling Bearer, LNK and PHY layer, and the wireless network layer of described Iu interface is handled and comprised that RANAP handles.

Interconnect scheme two:

Shown in Figure 25 a, Figure 25 b and Figure 25 c, use three kinds of embodiment of the present invention, the characteristics of these three kinds of execution modes are: the reference point V interconnection in the DSL network of BS in the cordless communication network or WA1 and DSL network, cordless communication network WA2 or CN and BRAS are in reference point A10 interconnection, thus the interconnection of realization cordless communication network and DSL network.This scheme belongs to the loose coupling scheme, and it can support unified to charge, unified customer service (Customer Care) and unified certification.The difference of above-mentioned three kinds of execution modes is, only has WA2 in Figure 25 a illustrated embodiment, only has WA1 in Figure 25 b illustrated embodiment, not only has WA1 but also have WA2 in Figure 25 c illustrated embodiment.

Referring to Figure 25 a, 25b, 25c, UE at first sets up RRC by the chain of command protocol stack and connects when data communication, begin to carry out the foundation of RAB after consulting with core net, and the process of setting up of RAB is accompanied by the foundation of user's face RB.After RAB set up successfully, the user just can transmit data by the user plane bearer of having set up.The compression and decompression function of PDCP can be enabled, and also can not enable.Signaling set up flow process be UE be connected with RRC between the UTRAN set up successfully after, UE sets up by RNC and is connected with the signaling of CN, also cries " the NAS signaling is set up flow process ", is used for the Signalling exchange NAS information of UE and CN, as authentication, service request, connection foundation etc.Be example to have enabled the compression and decompression function below, specify the transmission course of user's face and chain of command data.Wherein, the RNL of Uu interface comprises PDCP, RLC and MAC at user's face, comprises RRC, RLC and MAC at chain of command.

For Figure 25 a, there are three kinds of implementation patterns again, be respectively:

Pattern (1): WA2 is equivalent to the function of RNC, i.e. WA2=RNC;

Referring to Figure 26 and Figure 27, it is respectively at the user's face of the pattern (1) in Figure 25 a illustrated embodiment and the protocol stack structure schematic diagram of chain of command.In this example, SGSN and GGSN in the CN are combined into a new network element, and this network element is called IGSN.Based on this protocol stack structure:

Issue RNL after being packaged into packet for the application layer data of up user face data: UE, this packet can be User IP packet or ppp protocol bag.RNL compresses this packet header, increases the RFL that issues physical layer behind the header of agreement regulation such as the RLC/MAC header, and RFL carries out operation such as coded modulation and then sends to UTRAN by the Uu interface to the packet that receives.The RFL of Node B goes into this packet encapsulation in the Frame Protocol FP frame after receiving packet among the UTRAN, and the FP frame is added the IP head promptly after IP handles, and is that the FP/IP frame mails to WA2 by Iub interface with the IP bag after handling.And the Iub interface Frame Protocol FP/IP frame between Node B and WA2 directly is carried on the aggregation networks in the DSL network.At protocol stack shown in Figure 26, the specific implementation process is:
