Description
Technical Field
The present invention relates to mobile communication technology, and in particular, to access network technology for third generation mobile communication systems.
Background
In the world today, packet networks including Internet Protocol (IP) are rapidly developed, including public Internet/enterprise Internet/community broadband access networks, because of low cost, rich interfaces, large bandwidth, and end-to-end application, IP technology is widely used as a wide area network connection technology in the world, and thus, a new transmission solution is provided for operators. The third Generation Partnership Project (3rd Generation Partnership Project, abbreviated to "3 GPP") explicitly incorporates IP transport into features in the R5 protocol, in order to meet networking requirements of different operators. However, the traditional IP network cannot provide a better quality of Service (QoS), so there is a certain risk in transmitting voice traffic through IP.
Universal Mobile Telecommunications System (UMTS) is a Universal Mobile Telecommunications System.
UMTS is a solution proposed by the European Standards Institute (ETSI for short) and intended for smooth transition to third-generation mobile Communication based on Global System for mobile Communication (GSM) networks. Wideband Code Division Multiple Access (WCDMA) is one of the International standards for third generation mobile communications worldwide accepted by the International Telecommunications Union (ITU). The mobile communication system may also be a third generation mobile communication system which is the first commercial in the world, and is also a standard of Frequency Division Duplex (FDD) frequency band of the european third generation mobile communication system. UMTS is also commonly referred to as WCDMA communication system, since it employs Wideband Code Division Multiple Access (WCDMA) air interface technology.
One advantage of UMTS is compatibility with existing legacy GSM systems. Thus, the GSM system will transition to UMTS in stages. The General Packet Radio Service (GPRS) that has been proposed at present provides a connectionless Service to a GSM network, expands the Service functions and flexibility of a GSM system, and increases the transmission rate of packet data, which is called "2.5-generation GSM" mobile communication. And gradually transits to a third generation mobile communication system (UMTS).
The structure of the UMTS system will be described with reference to fig. 1.
As shown in fig. 1, the UMTS system has a structure similar to that of a second-generation mobile communication system, and is composed of User Equipment (User Equipment, abbreviated as "UE") such as a mobile phone, a portable computer, and a vehicle-mounted phone, a universal mobile telecommunications system Terrestrial Radio Access Network (UMTS Terrestrial Radio Access Network, abbreviated as "UTRAN") responsible for processing all Radio-related functions, and a Core Network (Core Network, abbreviated as "CN") responsible for processing all voice calls and data connections in the UMTS system and implementing switching and routing functions with an external Network.
The CN is logically divided into a Circuit Switching (CS) domain and a Packet Switching (PS).
And the UTRAN includes one or more Radio Network Subsystems (RNS). As shown in fig. 2, each RNS is composed of a Radio Network Controller (RNC) and one or more Base Station nodes (Node Base Station, NodeB). Wherein, the RNC is connected with the CN through an Iu interface; NodeB and RNC are connected through Iub interface; the RNCs are connected by an Iur interface, which may be implemented by direct physical connection between RNCs or by transport network connection.
In the above structure, the RNC is responsible for allocating and controlling the Radio resources of the NodeB connected to or related to the RNC, in other words, is responsible for controlling the Radio resources of the UTRAN, and mainly completes the functions of Radio Resource Control (RRC) such as connection establishment and disconnection, handover, macro diversity combining, and Radio Resource management Control. The specific functions are as follows: executing system information broadcasting and system access control functions; mobility management functions such as handover and SRNC migration; and the wireless resource management and control functions comprise macro diversity combination, power control, wireless bearer allocation and the like.
The NodeB is responsible for completing the conversion of the data flow between the Iub interface and the Uu interface, and also participates in a part of radio resource management. Specifically, it comprises a radio transceiver and a baseband processing unit, as above, interconnected with RNC via standard Iub interface, mainly completing the processing of Uu interface physical layer protocol. Its main functions include spread spectrum, modulation, channel coding and de-spreading, demodulation, channel decoding, and the function of mutual conversion between baseband signal and radio frequency signal.
Having described the general structure of the UMTS system and the involved UTRAN network with reference to fig. 1 and 2, the Iub interface protocol stack is generally described below, as shown in fig. 3.
The Iub interface protocol stack is divided into a radio network control plane, a transport network control plane and a user plane. The bearer layer has two transmission modes, Asynchronous Transfer Mode (ATM for short) and Internet Protocol (IP for short).
When the transmission is carried out in the ATM mode, the transmission Layer of the control plane of the wireless Network uses SSCF-User Network Interface (UNI for short)/SSCOP/ATM adaptation Layer (AAL for short) 5/ATM, the control plane of the transmission Network uses ALCAP/SSCF-UNI/SSCOP/AAL5/ATM, and the transmission Layer of the User plane uses AAL 2/ATM.
When transmitting in the IP mode, the transport Layer of the radio network Control plane uses Stream Control Transmission Protocol (SCTP)/IP/Data Link Layer, and the User plane transport Layer uses User Datagram Protocol (UDP)/IP/Data Link Layer, and there is no transport network Control plane. Different channels of the user plane use different Frame Protocols (FP), including common CHannel Random Access CHannel (RACH), FP/Paging CHannel (PCH), FP/Forward Access CHannel (FACH), Dedicated CHannel (DCH), FP, High Speed Downlink Packet Access (HSDPA) CHannel handshake signal (DSCH) FP, other channels, such as DSCH FP, etc
Voice and data of User Equipment (UE) are encapsulated in various FP frames and transmitted over the Iub interface using a transport layer (ATM or IP) function.
The Rate of WCDMA voice traffic includes 12.2k/10.2k/7.95k/7.4k/. for example/4.75 k Adaptive Multi-Rate (Adaptive Multi-Rate, abbreviated as "AMR") (except for wideband AMR), where 12.2k AMR is mainly used and the Rate of data traffic includes 8k/16k/32k/64k/128k/144k/256k/384k/2048k/. for example. Due to the high rate of data traffic supported, the required bandwidth is much greater than voice.
As is known, in the initial application of WCDMA network, mainly voice is used as the main, the proportion of data services used by users is not high, so the initial network has relatively low requirement on the Iub interface transmission bandwidth, and the transmission bandwidth requirement can be met by using a single or multiple E1 interfaces.
However, with the development of networks, the proportion of data services used by users will increase continuously, and particularly after introducing High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA), the transmission rate of each cell can be increased to more than 10M, so the required Iub interface transmission bandwidth will increase continuously, and will be as many as several tens of E1/T1.
The operator can solve the transmission problem by self-establishing a transmission network or renting a transmission special line of other operators, and the increase of the transmission bandwidth requirement requires the operator to expand the self-establishing transmission network or increase the rented line.
In spite of the expansion of the self-established transmission network and the increase of the leased line, the operators need to increase the investment, which may generate a large amount of cost. Considering that fixed network broadband is rapidly popularized and well recognized with high bandwidth and low cost, wireless broadband charges of mobile operators will also follow to maintain competitiveness, and if data service income and transmission cost of the operators cannot be kept consistent, the profit level of the operators will be seriously affected, so that the transmission problem will be an urgent problem to be solved by the operators, and the operators will directly face a choice no matter whether establishing own transmission networks or finding other cheap alternative technologies.
Disclosure of Invention
In view of the above, the main objective of the present invention is to provide a transmission system between a base station and a radio network controller and a method thereof, so that a high-bandwidth Iub interface transmission capability can be obtained at a low cost.
To achieve the above object, the present invention provides a transmission system between a base station and a radio network controller, comprising first and second transmission lines connecting the base station and the radio network controller, wherein,
the first transmission line is borne on the special transmission line and is used for transmitting voice service frames;
the second transmission line is loaded in the IP network and used for transmitting data service frames;
the base station and the wireless network controller are also used for judging the type of the service frame to be transmitted, if the service frame is a voice service frame, the service frame is transmitted through the first transmission line, and if the service frame is a data service frame, the service frame is transmitted through the second transmission line.
Wherein, the base station and the wireless network controller satisfy the following formula when setting the connection frame number for the voice service frame and the data service frame:
connection frame number of data service frame is equal to connection frame number of voice service frame + D
Wherein D is a difference between connection frame numbers converted from values of T2 to T1, T1 is a transmission delay measured in advance for the first transmission line, and T2 is a transmission delay measured in advance for the second transmission line.
In the system, the base station and the radio network controller configure a reception window for each of the first and second transmission lines in accordance with a delay of the transmission line, and a larger reception window is configured for the second transmission line.
In the system, if the first transmission line uses IP transmission, the first and second transmission lines are configured with different IP addresses, and the base station and the radio network controller implement the shunt transmission of the voice service frame and the data service frame by sending the two service frames to the different IP addresses; if the first transmission line uses asynchronous transfer mode, the first transmission line is configured with AAL2PVC (asynchronous transfer mode adaptation layer 2 permanent virtual line), the second transmission line is configured with IP address, and the base station and the wireless network controller realize the shunt transmission of the two service frames by respectively sending the voice service frame and the data service frame to the AAL2PVC and the IP address.
Further in the system, the IP network may be an IP public network.
In addition, in the system, the dedicated transmission line may be based on E1 or T1, and on E1 or T1 lines, the dedicated transmission line may transmit voice traffic frames in an IP over E1/T1 manner, or may transmit voice traffic in an Asynchronous Transfer Mode (ATM over E1/T1) manner.
The invention also provides a transmission method between the base station and the wireless network controller, wherein a first transmission line and a second transmission line exist between the base station and the wireless network controller, the first transmission line is carried on the transmission special line, and the second transmission line is carried on the IP network;
the method comprises the following steps:
and when receiving a service frame to be sent to the opposite side, the base station and the wireless network controller judge the type of the service frame, if the service frame is a voice service frame, the service frame is transmitted through the first transmission line, and if the service frame is a data service frame, the service frame is transmitted through the second transmission line.
Wherein the method further comprises the step of the base station and the radio network controller setting a connection frame number to the traffic frame before transmitting it, wherein,
the connection frame number of the voice service frame and the data service frame satisfies the following formula:
connection frame number of data service frame is equal to connection frame number of voice service frame + D
Wherein D is a difference between connection frame numbers converted from values of T2 to T1, T1 is a transmission delay measured in advance for the first transmission line, and T2 is a transmission delay measured in advance for the second transmission line.
In the method, a reception window is allocated to each of the first and second transmission lines in accordance with a delay of the transmission line, and a larger reception window is allocated to the second transmission line.
The comparison shows that the technical scheme of the invention is mainly different from the prior art in that two different transmission lines are used between the base station and the RNC, one transmission line is borne on a special transmission line and used for transmitting voice service frames, and the other transmission line is borne on an IP network and used for transmitting data service frames.
Different CFNs are set for voice traffic frames and data traffic frames according to a predetermined transmission delay. And a large reception window is set for a transmission line of the data traffic frame.
If the special transmission line uses IP transmission, the two service frames can be transmitted by different routes by setting different IP addresses; if ATM is used for the special transmission line, the shunting transmission of two kinds of service frames can be realized by configuring AAL2PVC and IP address.
The difference of the technical scheme brings obvious beneficial effects that part of data service frames with large data volume but low QoS requirements are transmitted through an IP network, and the transmission cost of the IP network is greatly lower than that of a special transmission line, so that compared with the mode of completely using the special transmission line in the prior art, the scheme of the invention can greatly reduce the cost. Meanwhile, the voice data with higher QoS requirement still keeps the mode of using the special transmission line, so that the user can not feel the difference.
By setting different CFNs for the two service frames, when the two service frames reach the base station through different transmission paths, the two frames falling in the same receiving window have the same CFN, so that the requirement on the buffer memory of the base station is reduced, and the minimum time delay of voice is ensured.
Because the transmission delay of the IP network is usually large and unstable, setting a large receiving window can ensure that the service frame falls in the receiving window even when there is large delay jitter.
The IP address setting mode provides a simple and practical realization method for the shunt transmission of two service frames.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.
A transmission system between a Node B and an RNC according to one embodiment of the present invention is shown in FIG. 5. The transmission system includes first and second transmission lines connecting the Node Bs and the RNC.
The first transmission line is carried on the transmission special line and is used for transmitting voice service frames. In this embodiment, the private line of transmission is E1/T1.
The second transmission line is carried in the IP network, and is used to transmit the data service frame.
And, the Node B and the RNC are also used to determine the type of the service frame to be transmitted, and if the service frame is a voice service frame, the service frame is transmitted through the first transmission line as shown in fig. 5, and if the service frame is a data service frame, the service frame is transmitted through the second transmission line.
Different IP addresses can be configured for the first transmission line and the second transmission line, the Node B and the RNC realize the shunt transmission of the voice service frame and the data service frame by sending the voice service frame and the data service frame to different IP addresses, thereby conveniently realizing the shunt transmission of voice E1/T1 and data IP network. Or the first transmission line uses asynchronous transfer mode, the AAL2PVC is configured for the first transmission line, the IP address is configured for the second transmission line, and the Node B and the RNC realize the shunt transmission of the two service frames by respectively sending the voice service frame and the data service frame to the AAL2PVC and the IP address. Other implementations are not excluded in other embodiments of the invention.
Therefore, the above scheme considers and solves the problems that the traditional IP network can not provide better QoS and the voice service has quality risk through IP transmission, which are mentioned in the prior art.
Specifically, the present invention adopts the above-mentioned shunt transmission mode for the condition that the voice service frame and the data service frame need to be transmitted, that is, the voice is transmitted by using the transmission special line, and the data is transmitted through the IP public network. Under the condition, the voice QoS requirement, namely smaller time delay and time delay jitter, can be met, and the transmission bandwidth requirement of the data service is solved by utilizing other transmission technologies, namely the data service requires high bandwidth but allows great time delay and time delay jitter.
Because the bandwidth required by the voice service is smaller, according to the scheme, an operator only needs to use fewer special transmission lines, data is transmitted through an IP network, the cost of each Mbps is low, the bandwidth cost ratio of the IUB interface is effectively improved, and therefore the operation expense of the operator can be greatly reduced. In other words, not only the QOS guarantee of the special transmission line is fully utilized, but also the advantages of high bandwidth and low cost of the IP network are utilized, thereby solving the contradiction between the bandwidth and the cost.
In this embodiment, it is further noted that, because a Frame Protocol (Frame Protocol, abbreviated as "FP") needs to maintain a strict synchronization relationship, that is, to ensure air interface synchronization, it is necessary to ensure that time offsets of voice frames and data frames transmitted through different paths using the same air interface physical channel and the same CFN Frame number to reach the NODEB are controlled within a certain range, that is, within a receiving window. In this embodiment, the voice and the data use two different CFNs to compensate different time delays in the transmission process, when the FP sends data, different CFNs are filled in the voice frame and the data frame, so that when the voice frame and the data frame reach the NodeB through different transmission paths, two frames falling in the same receiving window have the same CFN, thereby reducing the requirement for the buffer of the NodeB and ensuring that the voice has the minimum time delay.
Specifically, in this embodiment, when the Node B and the RNC set the CFN for the voice service frame and the data service frame, the following formula should be satisfied:
CFN of data service frame ═ CFN + D of voice service frame
Where D is a difference in CFN converted from the values of T2 to T1, T1 is a transmission delay previously measured for the first transmission line, and T2 is a transmission delay previously measured for the second transmission line.
FIG. 4 is a PF synchronization relationship diagram. Wherein,
TOA is Time of arrival (Time of Arrial)
LTOA is the Latest Arrival Time (late Time of Arrival)
TOAWS is the starting point of the TOA Window (TOA Window Startpoint)
TOAWE is the end point of the TOA Window (TOA Window Endpoint)
Tproc is the Processing time before air-interface transmission (Processing time before transmission-interface)
In addition, it is necessary to consider that the delay jitter range of the IP network is large, and a large receiving window may be configured, so that even if the data packet has large delay jitter, it can be guaranteed to fall within the receiving window. Therefore, in this embodiment, in the Node B and the RNC, one receiving window is configured for each of the first and second transmission lines according to the delay of the transmission line, wherein a larger receiving window is configured for the second transmission line for transmitting the data traffic frame.
It can be understood from the above explanation and analysis that the present invention adopts the shunt transmission for the voice service frame and the data service frame, can effectively solve the contradiction between the IUB interface bandwidth and the cost, and has higher application value.
FIG. 6 is a flowchart of a transmission method between a Node B and an RNC according to the above embodiments. It should be noted that the implementation of the present embodiment is based on the above mentioned transmission system between the Node B and the RNC, that is, in the transmission system related to the method, a first transmission line and a second transmission line exist between the Node B and the RNC, where the first transmission line is carried on the dedicated transmission line, and the second transmission line is carried on the IP network. In the method, when receiving a service frame to be sent to the opposite side, the Node B and the RNC judge the type of the service frame, if the service frame is a voice service frame, the service frame is transmitted through a first transmission line, and if the service frame is a data service frame, the service frame is transmitted through a second transmission line. The process of the present invention is described in detail below with reference to fig. 6.
First at step 610: the RNC judges the type of the service frame, and if it is a voice service frame, it proceeds to step 620, and if it is a data service frame, it proceeds to step 640;
in step 620: normally setting CFN because the frame is judged to be a voice service frame;
at step 630: sending the voice service frame to an IP address 1, and then entering step 660;
at step 640: since the determination is that the frame is a data service frame, the set CFN is a reduced value of adding the delay difference to the normal CFN. Specifically, the CFN of the voice service frame and the data service frame satisfies the following formula:
CFN of data service frame ═ CFN + D of voice service frame
Where D is a difference in CFN converted from the values of T2 to T1, T1 is a transmission delay previously measured for the first transmission line, and T2 is a transmission delay previously measured for the second transmission line.
As described above, this is because a Frame Protocol (FP) needs to keep a strict synchronization relationship, that is, to ensure air interface synchronization, and therefore, it is necessary to ensure that time offsets of voice frames and data frames transmitted through different paths using the same air interface physical channel and the same CFN Frame number to reach the NODEB are controlled within a certain range, that is, within a receiving window. In this embodiment, the voice and the data use two different CFNs to compensate different time delays in the transmission process, when the FP sends data, different CFNs are filled in the voice frame and the data frame, so that when the voice frame and the data frame reach the NodeB through different transmission paths, two frames falling in the same receiving window have the same CFN, thereby reducing the requirement for the buffer of the NodeB and ensuring that the voice has the minimum time delay.
In step 650: the data traffic frame is sent to IP address 2, and then step 660 is performed. It should be noted that, the first and second transmission lines are configured with different IP addresses, the service frames sent to different IP addresses have different routes, and the Node B and the RNC implement the shunt transmission of the two frames by sending the voice service frame and the data service frame to different IP addresses.
Finally, at step 660: and the base station combines the received two service frames according to the CFN. In the Node B and the RNC, a receiving window is configured for each of the first and second transmission lines according to the delay of the transmission line, wherein a larger receiving window is configured for the second transmission line, which is to consider that the delay jitter range of the IP network is larger, and by configuring the larger receiving window, even if the data message has larger delay jitter, the data message can be ensured to fall in the receiving window.
Another embodiment of the present invention is described below, which is different from the previous embodiment in that the first transmission path for transmitting voice traffic frames uses an ATM scheme (ATM over E1/T1), and the first transmission path in the previous embodiment uses an IP scheme (IP over E1/T1). Therefore, the first transmission path adopts ATM, and the second transmission path adopts IP, so as to form a heterogeneous IUB interface. In this embodiment, AAL2PATHID identification (corresponding to PVC determined by VPI/VCI at the bottom layer) is used in the transmission of voice traffic frames, which is different from the IP address used in the previous embodiment.
While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
