The interconnecting method that the present invention proposes as the wireless extension of the wired access of copper cash broadband network, is applicable to fixed wireless, nomadic, portable and mobile access application.Provide a kind of evolution approach for DSL Virtual network operator development wireless network simultaneously.

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 BRAS are in reference point A10 interconnection, thus the interconnection of realization cordless communication network and DSL network.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 (1) one embodiment of the pattern 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, RadioFrequency Layer), RFL carries out operation such as coded modulation back and sends to UTRAN by the Uu interface to the packet that receives.The RFL of Node B receives behind the packet and this packet encapsulation to be gone into Frame Protocol (FP FramingProtocol) in the frame, adds the IP head promptly after IP handles with the FP frame, and the IP bag after handling is mail to WA2 by Iub interface among the UTRAN.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 DOCSIS 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 DOCSIS 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 Node B 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 layer (the IP layer is at FP, and Signaling Bearer is at NBAP, below similar content with) directly are carried on the DSL network.Described wireless network layer comprises FP or NodeB application protocol (NBAP, NodeB ApplicationProtocol, the NBAP frame exists only between Node B and the RNC), described signaling bear layer comprises Simple Control Transmission Protocol (SCTP, Simple Control Transmission Protocol) 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 DOCSIS 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 DOCSIS 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.

At CN, SGSN does the transport network layer and the wireless network layer of Iu interface and handles, and obtains the signaling message of UE side, as GMM, SM, SMS message, continues subsequent treatment according to existing mode then.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 signaling message of being issued this UE by core network by opposite process.

Referring to Fig. 7 and Fig. 8, it is respectively at the user's face of another embodiment of pattern (1) in Fig. 4 a illustrated embodiment and the protocol stack structure schematic diagram of chain of command.The difference of itself and Fig. 5 and protocol stack shown in Figure 6 is: Node B and DSL Modem are integrated into a logic entity, and it is referred to as " Node B+DSL Modem ".SGSN in the core net and GGSN united two into one is integrated into a new network element, and this new network element is referred to as IGSN (integrated GPRS Support Node).Because variation has taken place protocol stack structure, so treatment step also can change accordingly in puberty, only the processing difference with Fig. 5 and Fig. 6 described below, and something in common repeats no more.

For up user face data: after UE sends to UTRAN with data by the Uu interface, to receive behind the packet in the FP frame that data envelope packed into by the Node B+DSL Modem in the UTRAN, the FP frame is added the IP head promptly after IP handles, the IP bag after handling is mail to WA2 by Iub interface.And the Iub interface Frame Protocol FP/IP frame between Node B+DSL Modem and WA2 directly is carried on the DSL network, concrete two layers of bridging technology or three layers of route technology of adopting.That is to say, the FP/IP frame is divided into the ETH frame, do the DSL physical frame that the DOCSIS modulation treatment is converted to the twisted-pair feeder transmission that is fit in the cable network then, be sent to DSLAM through twisted-pair feeder by Node B+DSL Modem.Identical with the processing of Fig. 5 afterwards.That is to say, compare that user face data can reach WA2 through DSLAM and BRAS with Fig. 5.

At CN, IGSN does the transport network layer and the wireless network layer of Iu interface and handles, and User IP packet that its data that receive from GTP tunnel are exactly UE or ppp protocol bag, IGSN are issued external network with the form of User IP packet or ppp protocol bag again.

For up chain of command data: after the UE side sends to UTRAN with signaling message by the Uu interface, the RFL of Node B+DSL Modem receives behind the packet in the Iub interface wireless network layer frame that this data envelope packed in the UTRAN, as be encapsulated as the FP frame, mail to WA2 by the carrying of Iub interface transport network layer.The wireless network layer of the Iub interface between Node B+DSL Modem and WA2 directly is carried on the DSL network as the IP layer or the signaling bear layer of FP or NBAP and transport network layer.Concrete two layers of bridging technology or three layers of route technology of adopting.That is to say, FP/IP frame or NBAP/SCTP/IP frame are divided into the ETH frame, do the DSL physical frame that the DOCSIS modulation treatment is converted to the twisted-pair feeder transmission that is fit in the cable network then, be sent to DSLAM through twisted-pair feeder by Node B+DSL Modem.Identical with the processing of Fig. 6 afterwards.Compare with Fig. 6, user face data can reach WA2 through DSLAM and BRAS.

At CN, IGSN does the transport network layer and the wireless network layer of Iu interface and handles, and obtains the signaling message of UE side, as GMM, SM, SMS message, continues subsequent treatment according to existing mode then.

Referring to Fig. 9 and Figure 10, it is respectively at the user's face of (2) one embodiment of the pattern in Fig. 4 a illustrated embodiment and the protocol stack structure schematic diagram of chain of command.The difference of itself and Fig. 7 and protocol stack shown in Figure 8 is: WA2 is equivalent to the function of RNC and SGSN.Like this, the processing for CN only need be GGSN no longer needs to do the processing of SGSN.Because variation has taken place protocol stack structure, so treatment step also can change accordingly in puberty, only the processing difference with Fig. 7 and Fig. 8 described below, and something in common repeats no more.

For up user face data: 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 Node B+DSL Modem 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 gn interface protocol stack with this packet and handles the back and send to network element among the CN by GTP tunnel.Described gn interface protocol stack is handled the processing that comprises GTP user's face (GTP-U), UDP, IP, LNK, PHY layer.

At CN, GGSN does the gn interface protocol stack and handles, and User IP packet that its data that receive from GTP tunnel are exactly UE or ppp protocol bag, GGSN are issued external network with the form of User IP packet or ppp protocol bag again.

For up chain of command data: WA2 receives data by PHY, obtain FP/IP frame or signaling bear layer 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+DSL Modem and WA2 directly are carried on the DSL network, therefore, can regard WA2 as and directly obtain FP/IP frame or NBAP frame from Iub interface this moment, if WA2 receives the NBAP frame, then this NBAP frame is carried out respective handling; If WA2 receives the FP/IP frame, then with the packet that obtains after this FP/IP frame decapsulation among the RNL, after the RNL layer is handled, WA2 obtains the signaling message of UE side, as the signaling message of GMM, SM, SMS message or rrc layer and carry out respective handling, as connect, measurement report etc., promptly WA2 finishes the chain of command function of RNC and SGSN.Set up, safeguard or release user face GTP tunnel by gn interface chain of command GTP agreement between WA2 and GGSN.Described gn interface protocol stack is handled the processing that comprises GTP chain of command (GTP-C), UDP, IP, LNK, PHY layer.

Certainly, when reality is implemented pattern (2) in Fig. 4 a illustrated embodiment, can also be separate between Node B and the DSL Modem, each is a logic entity independently naturally, at this moment, the processing of this part is identical with processing procedure shown in Figure 6 with Fig. 5, repeats no more herein.

Referring to Figure 11 and Figure 12, it is respectively at the user's face of (3) one embodiment of the pattern in Fig. 4 a illustrated embodiment and the protocol stack structure schematic diagram of chain of command.The difference of itself and Fig. 7 and protocol stack shown in Figure 8 is: WA2 is equivalent to the function of RNC, SGSN and GGSN.Like this, no longer need carry out the processing of SGSN and GGSN for CN, other are handled as usual.Because variation has taken place protocol stack structure, so treatment step also can change accordingly in puberty, only the processing difference with Fig. 7 and Fig. 8 described below, and something in common repeats no more.

For up user face data: 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 frame between Node B+DSL Modem 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 decapsulation among the RNL, afterwards, WA2 is routed to external network with this packet by CN.

At CN, no longer do the processing of SGSN and GGSN, only do routing function.

For up chain of command data: WA2 receives data by PHY, obtain FP/IP frame or signaling bear layer 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 frame between Node B+DSL Modem and WA2 directly are carried on the DSL network, therefore, can regard WA2 as and directly obtain FP/IP frame or NBAP frame from Iub interface this moment, if WA2 receives the NBAP frame, then this NBAP frame is carried out respective handling; If WA2 receives the FP/IP frame, then with the packet that obtains after this FP/IP frame decapsulation among the RNL, after the RNL layer is handled, WA2 obtains the signaling message of UE side, as the signaling message of GMM, SM, SMS message or rrc layer, and carry out respective handling, as connect, measurement reports etc., promptly WA2 finishes the chain of command function of RNC, SGSN and GGSN.

At CN, no longer do the processing of SGSN and GGSN, only do routing function.

Certainly, when reality is implemented pattern (3) in Fig. 4 a illustrated embodiment, also can be separate between Node B and the DSL Modem, each is a logic entity independently naturally, at this moment, the processing of this part is identical with processing procedure shown in Figure 6 with Fig. 5, repeats no more herein.

Referring to Fig. 4 b, in the base station BS that is used for wireless access and control, management, WA1 is set, BS has access to spider lines with the data in the cordless communication network by DSL Modem by the interconnection of the reference point T in WA1 and the DSL network; BRAS in the cable network inserts core net by reference point A10 with the data in this DSL network, thereby realizes the interconnection of cable network and wireless network.In this interconnection mode, network element BS, WA1 can logically separate with DSL Modem or be integrated.

For Fig. 4 b, there are two kinds of implementation patterns again, be respectively:

Pattern (4): WA1 is equivalent to the function of RNC, i.e. WA1=RNC;

Pattern (5): WA1 is equivalent to the function of RNC and SGSN, i.e. WA1=RNC+SGSN.

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

Referring to Figure 13 and Figure 14, it is respectively at the user's face of (4) one embodiment of the pattern in Fig. 4 b illustrated embodiment and the protocol stack structure schematic diagram of chain of command.In this example, be provided with WA1 in the Node B,, the Node B that is provided with WA1 be called Node B+WA1 at this.

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.Because WA1 is equivalent to the function of RNC, therefore, after the RFL of Node B+WA1 receives packet among the UTRAN, remove protocol header successively, through reconfigure and a decompression after, by GTP tunnel packet is forwarded to CN through the Iu interface, WA1 among the Node B and GTP tunnel agreement, UDP and the IP between CN directly are carried on the DSL network.Can adopt two layers of bridging technology or three layers of route technology to realize transmission between the concrete SGSN in WA1 and CN, at protocol stack shown in Figure 13, the specific implementation process is:

Pattern (4): WA1 is equivalent to the function of RNC, i.e. WA1=RNC;

Referring to Figure 32 and Figure 33, it is respectively at the user's face of (4) one embodiment of the pattern in Figure 25 b illustrated embodiment and the protocol stack structure schematic diagram of chain of command.In this example, be provided with WA1 in the Node B,, the Node B that is provided with WA1 be called Node B+WA1 at this.

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.Because WA1 is equivalent to the function of RNC, therefore, after the RFL of Node B+WA1 receives packet among the UTRAN, remove protocol header successively, through reconfigure and a decompression after, by GTP tunnel packet is forwarded to CN through the Iu interface, WA1 among the Node B and GTP tunnel agreement, UDP and the IP between CN directly are carried on the aggregation networks in the DSL network.At protocol stack shown in Figure 32, the specific implementation process is:

Node B+WA1 is divided into Ethernet ETH frame with the GTP/UDP/IP bag, sends to BRAS at ethernet physical layer PHY through the aggregation networks in the DSL network; BRAS is converted to the ETH frame once more with the data that receive, and the ETH frame is done the ethernet mac processing obtain the IP bag, and this IP bag is done the LNK encapsulation again, and afterwards, the physical layer PHY of Data-carrying between BRAS and CN after BRAS will encapsulate again is sent to CN and does further processing.

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+WA1 removes protocol header successively with this packet after receiving packet in the UTRAN, merges through reorganization, and data are issued the RRC agreement of RNL, resolves signaling message, carries out respective handling, as connecting foundation, measurement report etc.But for GMM/SM/SMS message, Node B+WA1 will directly deliver the CN processing to corresponding message by the wireless network layer (as NANAP) and the transport network layer of Iu interface.Described transport network layer comprises SCCP/M3UA/SCTP/IP/LNK/PHY, and wherein M3UA/SCTP/IP is Signaling Bearer among the figure.The WA1 in the NodeB and the wireless network layer (as NANAP) of the Iu interface between CN and transport network layer (as SCCP/M3UA/SCTP/IP) directly are carried on the aggregation networks in the DSL network.At protocol stack shown in Figure 33, the specific implementation process is:

Node B+WA1 is divided into Ethernet ETH frame with the RANAP/SCCP/M3UA/SCTP/IP bag, sends to BRAS at ethernet physical layer PHY through the aggregation networks in the DSL network; BRAS is converted to the ETH frame once more with the data that receive, and the ETH frame is done the ethernet mac processing obtain the IP bag, and this IP bag is done the LNK encapsulation again, and afterwards, the physical layer PHY of Data-carrying between BRAS and CN after BRAS will encapsulate again is sent to CN and does further processing.

Referring to Figure 34 and Figure 35, it is respectively at the user's face of (5) one embodiment of the pattern in Figure 25 b illustrated embodiment and the protocol stack structure schematic diagram of chain of command.The difference of itself and Figure 32 and protocol stack shown in Figure 33 is: WA1 is equivalent to the function of RNC and SGSN.Like this, the processing for CN only need be GGSN no longer needs to do the processing of SGSN.Because variation has taken place protocol stack structure, so treatment step also can change accordingly in puberty, only the processing difference with Figure 32 and Figure 33 described below, and something in common repeats no more.

For up user face data: after UE sends to UTRAN with data by the Uu interface, because WA1 is equivalent to the function of RNC and SGSN, therefore, after receiving packet by the RFL of Node B+WA1 in the UTRAN, remove 0 of agreement newspaper successively, through reconfiguring and after head compression handles, by GTP tunnel packet is forwarded to CN through gn interface, and GTP tunnel agreement, UDP and IP between WA1 and CN directly are carried on the aggregation networks in the DSL network.

For up chain of command data: after the UE side sends to UTRAN with signaling message by the Uu interface, because WA1 is equivalent to the function of RNC and SGSN, therefore, the RFL of Node B+WA1 removes protocol header successively with this packet after receiving packet in the UTRAN, merge through reorganization, data are issued RNL, after the RNL layer is handled, obtain the signaling message of UE side, as the signaling message of GMM, SM, SMS message or rrc layer.Set up, safeguard or discharge user's face GTP tunnel that GTP tunnel agreement, UDP and the IP between NodeB+WA1 and GGSN directly is carried on the aggregation networks in the DSL network between Node B+WA1 and GGSN by gn interface chain of command GTP agreement.Described gn interface protocol stack is handled the processing that comprises GTP chain of command (GTP-C), UDP, IP, LNK, PHY layer.

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

Referring to Figure 36 and Figure 37, it is respectively at the user's face of (6) one embodiment of the pattern in Figure 25 c illustrated embodiment and the protocol stack structure schematic diagram of chain of command.In this example, be provided with WA1 in the Node B,, the Node B that is provided with WA1 be called Node B+WA1 at this; BRAS and WA2 close and are made as a logic entity, and it is referred to as BRAS+WA2.

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.Because WA1 is equivalent to the function of RNC, WA2 is equivalent to the function of SGSN, therefore, after the RFL of Node B+WA1 receives packet among the UTRAN, remove protocol header successively, through reconfiguring and after the head compression handles, packet being forwarded to BRAS+WA2 through the Iu interface by GTP tunnel.

Node B+WA1 is divided into Ethernet ETH frame with the GTP/UDP/IP frame and is sent to BRAS+WA2 and does further processing;

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+WA1 removes protocol header successively with this packet after receiving packet in the UTRAN, merges through reorganization, and data are issued the RRC agreement of RNL, resolves signaling message, carries out respective handling, as connecting foundation, measurement report etc.But for GMM/SM/SMS message, Node B+WA1 will directly deliver the BRAS+WA2 processing to corresponding message by the wireless network layer (as NANAP) and the transport network layer of Iu interface.Described transport network layer comprises SCCP/M3UA/SCTP/IP/LNK/PHY, and wherein M3UA/SCTP/IP is the SignalingBearer among the figure.

Node B+WA1 is divided into Ethernet ETH frame with the RANAP/SCCP/M3UA/SCTP/IP frame, the ETH frame is carried on ethernet physical layer PHY is sent to BRAS+WA2 and does further processing.

BRAS+WA2 Ethernet PHY handles and obtains the ETH frame, the ETH frame is done the ethernet mac processing obtain the IP bag, obtains the UDP bag after the IP route, and BRAS+WA2 does Iu interface transport network layer and wireless network layer processing then, obtains GMM/SM/SMS message from RANAP.For the dsl data business, BRAS+WA2 only is IP/LNK/PHY to data and handles.

Referring to Figure 38 and Figure 39, it is respectively at the user's face of (7) one embodiment of the pattern in Figure 25 c illustrated embodiment and the protocol stack structure schematic diagram of chain of command.The difference of itself and Figure 36 and protocol stack shown in Figure 37 is: WA2 is equivalent to the function of SGSN and GGSN.Like this, do not need to do again the processing of SGSN and GGSN for CN.Because variation has taken place protocol stack structure, so treatment step also can change accordingly in puberty, only the processing difference with Figure 36 and Figure 37 described below, and something in common repeats no more.

At CN, no longer do the processing of SGSN and GGSN, only do routing function.

For up chain of command data, after BRAS+WA2 Ethernet PHY processing obtains the ETH frame, obtain the signaling bear layer data after the data that receive are done the LNK decapsulation, these data are converted to the SCCP frame, because the Iu interface frame agreement SCCP between WA1 and WA2 directly is carried on the DSL network, therefore, can regard WA2 as and directly obtain the SCCP frame from the Iu interface this moment, with the packet that obtains after this SCCP frame decapsulation among the RNL, as RANAP, afterwards, WA2 does RANAP with this packet and handles, obtain the signaling message of UE side, as GMM, SM, SMS message.The processing of the transport network layer of described Iu interface comprises the processing of SCCP, Signaling Bearer, LNK and PHY layer, and the processing of the wireless network layer of described Iu interface comprises that RANAP handles.

At CN, no longer do the processing of SGSN and GGSN, only do routing function.

Referring to Figure 40 and Figure 41, it is respectively at the user's face of (8) one embodiment of the pattern in Figure 25 c illustrated embodiment and the protocol stack structure schematic diagram of chain of command.The difference of itself and Figure 38 and protocol stack shown in Figure 39 is: WA1 is equivalent to RNC and SGSN, and WA2 is equivalent to the function of GGSN.Like this, do not need to do again the processing of SGSN and GGSN for CN.Because variation has taken place protocol stack structure, so treatment step also can change accordingly in puberty, only the processing difference with Figure 38 and Figure 39 described below, and something in common repeats no more.

For up user face data: after UE sends to UTRAN with data by the Uu interface, because WA1 is equivalent to the function of RNC and SGSN, therefore, after receiving packet by the RFL of the Node B+WA1 in the UTRAN, remove protocol header successively, through reconfigure and a decompression after, by GTP tunnel packet is forwarded to BRAS+WA2 through gn interface, and GTP tunnel agreement, UDP and IP between WA1 and WA2 are carried on directly on the aggregation networks in the DSL network.

BRAS+WA2 does the gn interface protocol stack and handles, and the data that receive from GTP tunnel are exactly User IP packet or the ppp protocol bag of UE, and BRAS+WA2 issues CN with the form of User IP packet or ppp protocol bag again.

At CN, no longer do the processing of SGSN and GGSN, only do routing function.

For up chain of command data, after the UE side sends to UTRAN with signaling message by the Uu interface, because WA1 is equivalent to the function of RNC and SGSN, therefore, the RFL of Node B+WA1 removes protocol header successively with this packet after receiving packet in the UTRAN, merges through reorganization, data are issued RNL, after the RNL layer was handled, BRAS+WA2 obtained the signaling message of UE side, as the signaling message of GMM, SM, SMS message or rrc layer.Set up, safeguard or release user face GTP tunnel by gn interface chain of command GTP agreement between Node B+WA1 and BRAS+WA2.Described gn interface protocol stack is handled the processing that comprises GTP chain of command (GTP-C), UDP, IP, LNK, PHY layer.

At CN, no longer do the processing of SGSN and GGSN, only do routing function.
