Universal mobile telecommunications system (Universal Mobile Telecommunications System is called for short " UMTS ").
UMTS is (the European Standards Institute of ETSI European Telecommunications Standards Institute, be called for short " ETSI ") propose, be intended to be smoothly transitted on global system for mobile communications (Global System for mobile Communication is called for short " the GSM ") network foundation solution of 3G (Third Generation) Moblie.Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access, be called for short " WCDMA ") be one of international standard of International Telecommunications Union's (International Telecommunications Union is called for short " ITU ") Global 3G mobile communication of admitting.Also can be described as the 3-G (Generation Three mobile communication system) that puts it into commercial operation the earliest in the world, is the standard of European 3-G (Generation Three mobile communication system) Frequency Division Duplexing (FDD) (FrequencyDivision Duplex is called for short " FDD ") frequency range simultaneously.Because UMTS adopts Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access is called for short " WCDMA ") air interface technologies, therefore, also the UMTS system is called the WCDMA communication system usually.
The advantage of UMTS is, and is compatible with existing traditional gsm system energy.Thus, gsm system will be stage by stage to the UMTS transition.GPRS (the GeneralPacket Radio Service that has now released, be called for short " GPRS "), provide connectionless service to the GSM network, the business function and the flexibility of gsm system have been expanded, improved transmission of packet data speed, " the 2.5 generation GSM " mobile communication of being known as.And progressively to 3-G (Generation Three mobile communication system) (UMTS) transition.
Introduce the structure of UMTS system below with reference to Fig. 1.
As shown in Figure 1, the UMTS system has adopted and the similar structure of second generation mobile communication system, by such as cell phone, portable computer, the subscriber equipment of vehicular phone and so on (User Equipment, be called for short " UE "), be responsible for to handle universal mobile telecommunications system grounding wireless access network (the UMTS Terrestrial Radio Access Network of all and wireless function associated, be called for short " UTRAN "), and be responsible for to handle that all voice calls are connected with data in the UMTS system, and the core net of the exchange of realization and external network and routing function (Core Net is called for short " CN ") constitutes.
Wherein CN is from being divided into circuit switching (Circuit Switching is called for short " CS ") territory and packet switching (Packet Switching is called for short " PS ") in logic.
And UTRAN comprises one or several RNS (Radio Network Subsystem is called for short " RNS ").As shown in Figure 2, each RNS is made up of a radio network controller (Radio NetworkController is called for short " RNC ") and one or more base-station node (Node Base Station is called for short " NodeB ").Wherein, be connected by the Iu interface between RNC and the CN; NodeB is connected by Iub interface with RNC; Connect by the Iur interface between the RNC, the Iur interface can connect by the connection of the direct physical between the RNC or by transmission network to be realized.
In said structure, RNC is responsible for distributing and is attached thereto with control or the Radio Resource of relevant NodeB, in other words, promptly be responsible for the Radio Resource of control UTRAN, mainly finish functions such as the connection foundation of Radio Resource control (Radio Resource Control is called for short " RRC ") and disconnection, switching, the merging of grand diversity, RRM control.Concrete function has: executive system information broadcast and system's access control function; Mobile management functions such as switching and SRNC migration; RRM and controlled function such as grand diversity merging, power control, radio bearer distribution.
NodeB then is responsible for finishing the conversion of the data flow between Iub interface and the Uu interface, also participates in a part of RRM simultaneously.Specifically, it comprises radio receiving-transmitting unit and Base-Band Processing parts, as above, by the Iub interface and the RNC interconnection of standard, mainly finishes 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.
Seen figures.1.and.2 the above general configuration of the UTRAN network having introduced the UMTS system and comprised is roughly introduced the Iub interface protocol stack, as shown in Figure 3 below.
The Iub interface protocol stack is divided into wireless network control face, transmission network chain of command, user's face.Bearing bed has asynchronous transfer mode (Asynchronous Transfer Mode is called for short " ATM ") and two kinds of transmission meanss of internetworking agreement (Internet Protocol is called for short " IP ").
When transmitting in the ATM mode, the transport layer of wireless network control face is used SSCF-User Network Interface (User Network Interface, be called for short " UNI ")/SSCOP/ATM adaptation layer (ATMAdaptation Layer, be called for short " AAL ") 5/ATM, the transmission network chain of command uses ALCAP/SSCF-UNI/SSCOP/AAL5/ATM, and user's face transport layer is used AAL2/ATM.
When transmitting in the IP mode, the transport layer of wireless network control face is used SCTP (Stream Control Transmission Protocol, be called for short " SCTP ")/IP/Data Link Layer, user's face transport layer is used User Datagram Protoco (UDP) (User Datagram Protocol, be called for short " UDP ")/IP/Data Link Layer, there is not the transmission network chain of command.The different channel of user's face uses different Frame Protocol (Frame Protocol, be called for short " FP "), comprise common signal channel Random Access Channel (RandomAccess CHannel, be called for short " RACH ") FP/ paging channel (Paging Channel, be called for short " PCH ") FP/ forward access channel (Forward Access Channel, be called for short " FACH ") FP, dedicated channel dedicated channel (Dedicate Channel, be called for short " DCH ") FP, high speed downlink packet inserts (HighSpeed Downlink Packet Access, be called for short " HSDPA ") channel handshake (Handshakingsignal)-DSCH Downlink Shared Channel (Downlink Shared Channel, be called for short " DSCH ") FP, other channels are as DSCH FP or the like
The voice-and-data of subscriber equipment (User Equipment is called for short " UE ") is encapsulated in the various FP frames, uses transport layer (ATM or IP) function, transmits at Iub interface.
The speed of WCDMA speech business comprises 12.2k/10.2k/7.95k/7.4k/ ... / 4.75k adaptive multi-rate (Adaptive Multi-Rate, be called for short " AMR ") (except the wideband A MR), wherein mainly use 12.2k AMR, the speed of data service comprises 8k/16k/32k/64k/128k/144k/256k/384k/2048k/ ...Because the speed of the data service of supporting is higher, therefore the bandwidth that needs is far longer than voice.
As everyone knows, at the WCDMA network application initial stage, mainly based on voice, the user uses the ratio of data service not high, so the network at initial stage is not high relatively to the Iub interface requirements for transmission, uses single or multiple E1 interfaces just can satisfy the transmission bandwidth requirement.
Yet, along with networks development, the user uses the ratio of data service to improve constantly, particularly introduce high speed downlink packet and insert (High Speed Downlink Packet Access, be called for short " HSDPA ") and high speed downlink packet insert after (High Speed Uplink Packet Access, abbreviation " HSUPA "), the transmission rate of each sub-district can be brought up to more than the 10M, therefore the Iub interface transmission bandwidth that needs will constantly increase, and will reach tens E1/T1.
The transmission special line solution transmission problem of other operators can or be rented by self-built transmission network by operator, and the increase of transmission bandwidth demand needs the self-built transmission network of operator's dilatation or increases leased line.
No matter be self-built transmission network of dilatation and increase leased line, need increase input in the operation commercial city, may produce a large amount of costs.Consider that the fixed network broadband obtains popularizing fast and highly approval with high bandwidth, low cost, the WiMAX rate of mobile operator also will be followed to keep competitiveness, if the data service income of operator and transmission cost can not be consistent, will have a strong impact on the level of profitability of operator, therefore transmission problem 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.

And Node B and RNC also are used to differentiate traffic frame type waiting for transmission, if the speech business frame, then as shown in Figure 5, by the transmission of first transmission line, if the data service frame, then by the transmission of second transmission line.
For first and second transmission lines, configurable different IP address, Node B and RNC be by sending to the shunt transmission that these two kinds of traffic frames are realized in different IP addresses with speech business frame and data service frame, realizes that easily voice walk E1/T1, and data are walked IP network and transmitted along separate routes.Also can use asynchronous transfer mode by first transmission line, be the first transmission line configuration AAL2 PVC, the second transmission line configuration IP address, Node B and RNC realize the shunt transmission of these two kinds of traffic frames by speech business frame and data service frame being sent to AAL2PVC and IP address respectively.In other embodiments of the invention, the implementation method of also not getting rid of other.
This shows that such scheme is to consider and solved in the prior art mentionedly, traditional IP can't provide QoS preferably, and there is the problem of quality risk in speech business by the IP transmission.
Specifically, the present invention adopts above-mentioned shunt transmission manner for the situation that needs transmitting voice service frame and data service frame, that is, allow voice use the transmission special line to transmit, and data are by the transmission of IP public network.In this case, both can satisfy the voice qos requirement, promptly less time delay and delay variation utilize other transmission technologys to solve the transmission bandwidth demand of data service again, that is, data service needs high bandwidth but allows very big time delay and delay variation.
Owing to the bandwidth that speech business is required is less, therefore according to such scheme, operator only need use less transmission special line, data are transmitted by IP network, the cost of every Mbps is cheap, effectively improves the bandwidth cost ratio of IUB interface, therefore can reduce the operation expenses of operator greatly.In other words, both having made full use of the transmission special line has QOS to guarantee, utilizes the high bandwidth low-cost advantage of IP network again, thereby solves the contradiction between bandwidth and cost.
Also it may be noted that in the present embodiment, because Frame Protocol (Frame Protocol, be called for short " FP ") need maintenance than strict synchronized relation, promptly, guarantee air interface synchronization, the moment Deviation Control that therefore must guarantee to use speech frame that the same physical channel of eating dishes without rice or wine, identical CFN frame number transmit by different paths and Frame arrival NODEB within the specific limits, that is, and in the receive window.In the present embodiment, voice-and-data uses two different CFN, compensate the different delay in the transmission course, when FP sends data, speech frame is filled in different CFN with Frame, and when guaranteeing that speech frame reaches NodeB with Frame by different transmission paths, two frames that drop in the same receiver window have identical CFN, to reduce requirement, guarantee that simultaneously voice have minimum time delay to the buffer memory of NodeB.
Specifically, in the present embodiment, Node B and RNC are speech business frame and data service frame when CFN is set, and should satisfy following formula:
The CFN+D of the CFN=speech business frame of data service frame
Wherein, D is the difference of the CFN that value was converted to of T2-T1, and T1 is the propagation delay time that first transmission line is measured in advance, and T2 is the propagation delay time that second transmission line is measured in advance.
Fig. 4 is a PF synchronized relation schematic diagram.Wherein,
TOA is the time of advent (Time of Arrial)
LTOA is time of advent (Latest Time of Arrival) the latest
TOAWS is the starting point (TOA Window Startpoint) of TOA window
TOAWE is the terminal point (TOA Window Endpoint) of TOA window
Tproc is the processing time (Processing time before transmission onair-interface) before eating dishes without rice or wine to send
In addition, need to consider that the delay variation scope of IP network is bigger, configurable bigger receiver window even data message has bigger delay variation like this, also can guarantee to drop in the receiver window.Therefore, in the present embodiment, in Node B and RNC,, be that first and second transmission lines respectively dispose a receiver window according to the time delay of transmission line, wherein, for being used for the bigger receiver window of second transmission line configuration of transmitting data service frame.
Be appreciated that by above-mentioned explanation and analysis the present invention adopts transmission along separate routes to speech business frame and data service frame, can effectively solve the contradiction between IUB interface bandwidth and the cost, have higher using value.
According to the Node B of the foregoing description and the transmission method flow chart between RNC as shown in Figure 6.Need to prove, the realization of present embodiment is based upon on the Node B and the transmission system basis between RNC that above mentions, that is to say, in the transmission system that this method relates to, there are first and second transmission lines between Node B and RNC, wherein first transmission line is carried on the transmission special line, and second transmission line is carried on IP network.In the method, Node B and RNC differentiate the type of this traffic frame when receiving the traffic frame that need send to the other side, if the speech business frame is then by the transmission of first transmission line, if the data service frame is then by the transmission of second transmission line.Below with reference to Fig. 6, describe process of the present invention in detail.
At first judge the type of traffic frame, if the speech business frame then enters step 620, if the data service frame then enters step 640 at step 610:RNC;
In step 620:, CFN is set normally then owing to judge it is the speech business frame;
In step 630: above-mentioned speech business frame is sent to IP address 1, after this enter step 660;
In step 640: owing to judge it is the data service frame, then the CFN of She Zhiing is the reduced value of increase delay inequality on normal CFN.Specifically, the CFN of speech business frame and data service frame satisfies following formula:
The CFN+D. of the CFN=speech business frame of data service frame
Wherein, D is the difference of the CFN that value was converted to of T2-T1, and T1 is the propagation delay time that first transmission line is measured in advance, and T2 is the propagation delay time that second transmission line is measured in advance.
As mentioned above, this is because Frame Protocol (Frame Protocol, be called for short " FP ") need maintenance than strict synchronized relation, promptly, guarantee air interface synchronization, the moment Deviation Control that therefore must guarantee to use speech frame that the same physical channel of eating dishes without rice or wine, identical CFN frame number transmit by different paths and Frame arrival NODEB within the specific limits, that is, and in the receive window.In the present embodiment, voice-and-data uses two different CFN, compensate the different delay in the transmission course, when FP sends data, speech frame is filled in different CFN with Frame, and when guaranteeing that speech frame reaches NodeB with Frame by different transmission paths, two frames that drop in the same receiver window have identical CFN, to reduce requirement, guarantee that simultaneously voice have minimum time delay to the buffer memory of NodeB.
In step 650: above-mentioned data service frame is sent to IP address 2, after this enter step 660.It is to be noted, first and second transmission line configuration have different IP addresses, the traffic frame that is sent to different IP addresses has different routes, and Node B and RNC are by sending to the shunt transmission that these two kinds of frames are realized in different IP addresses with speech business frame and data service frame.
At last, in step 660: the base station merges according to CFN two kinds of traffic frames receiving.In Node B and RNC, time delay according to transmission line, be that first and second transmission lines respectively dispose a receiver window, wherein, be the bigger receiver window of second transmission line configuration, this is to consider that the delay variation scope of IP network is bigger, by being the bigger receiver window of its configuration, even data message has bigger delay variation, also can guarantee to drop in the receiver window.
Introduce an alternative embodiment of the invention below, the difference of this embodiment and a last embodiment is, first transmission channel that is used for the transmitting voice service frame uses ATM mode (ATM over E1/T1), and first transmission channel uses IP mode (IP over E1/T1) among the last embodiment.Such first transmission channel adopts ATM, and second transmission channel adopts IP, constitutes the IUB interface of isomery.In the present embodiment, use AAL2 PATHID sign (corresponding to bottom is the PVC that VPI/VCI determines) during the transmitting voice service frame, use the IP address to have any different among a this point and the last embodiment.
Though by with reference to some preferred embodiment of the present invention, the present invention is illustrated and describes, those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
