Description
Technical field
The present invention relates to mobile communication system, particularly the signal transmission technology in the mobile communication system Radio Access Network.
Background technology
Mobile communication system can satisfy the requirement that people communicate whenever and wherever possible, has just obtained development rapidly after it occurs.Development along with mobile communication technology, simple conversation can not have been satisfied user's requirement, mobile communications network will be upgraded to 3G (Third Generation) Moblie (The Third Generation is called for short " 3G ") from second generation mobile communication (The Second Generation is called for short " 2G ").3G system and 2G system are very different, one of them important feature is that 3G system data business will account for very big proportion, and different business has different service quality (Quality of Service, be called for short " QoS "), such as occupying different bandwidth, has the different error rate etc., and along with the development of 3G technology, insert (High Speed Downlink Packet Access with high speed downlink packet, be called for short " HSDPA ") and CDMA 2000 (Code Division Multiple Access 2000, abbreviation " CDMA2000 ") the data-optimized technology such as (Evolution-Data Optimized are called for short " EV-DO ") of 1x evolution will provide more high-speed data transmission for the technology of representative.
Mobile communication system on function, can be rough be divided into core net (Core Network, be called for short " CN ") and wireless access network (Radio Access Network, abbreviation " RAN ").All voice calls are connected with data and the exchange and the routing function of realization and external network in the main treatment system of CN, and RAN mainly handles all and wireless access function associated.Wherein, equipment among the RAN mainly comprises base station transceiver (Base Transceiver Station, be called for short " BTS " or " base station ") and base station controller (Base Station Controller is called for short " BSC "), connect by certain interface between them.
3G (Third Generation) Moblie (The Third Generation, be called for short " 3G ") technical standard, comprise CDMA2000, Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access, be called for short " WCDMA ") and TD SDMA (Time Division Synchronous CodeDivision Multiple Access, be called for short " TD-SCDMA "), for the interconnection and interflow between different vendor's equipment, be and defined open standard interface between interior base station of mobile communication system RAN and the base station controller.By third generation partner program (3rd Generation Partnership Project, abbreviation " 3GPP ") in standardized WCDMA and the TD-SCDMA standard, the base station, be B node (Node B), and base station controller, be radio network controller (Radio Network Controller, be called for short " RNC "), between interface definition be the Iub interface of standard; In by the standardized CDMA2000 standard of third generation partner program 2 (3rd Generation Partnership Project2 is called for short " 3GPP2 "), the interface definition between base station and the base station controller is the Abis interface of standard.Because general apart from each other between base station and the base station controller is so generally need connect by transmission network between Iub and the Abis.
WCDMA and TD-SCDMA system with 3GPP are example, the option of the transport network layer of the protocol stack that Iub interface uses has asynchronous transfer mode (Asynchronous Transfer Mode, be called for short " ATM ") and two kinds of options of internetworking agreement (Internet Protocol is called for short " IP ").Wherein, the IP option is 3GPP the 5th edition (Release 5, are called for short " the R5 ") characteristic that version increases newly, and present most of NodeB products run on ATM RAN.
The protocol stack of WCDMA/TD-SCDMA Iub interface transport layer ATM option as shown in Figure 1.When WCDMA/TD-SCDMA Iub interface transport network layer was taked the ATM option, the transmission of Iub interface was taked the E1 transparent transmission usually or is inserted the mode of ATM transmission network.Need to prove that, E1 also can replace with T1/J1 herein, when data traffic is big even may be E3/T3 etc., this depends on specific implementation.
The protocol stack of WCDMA/TD-SCDMA Iub interface transport layer IP option as shown in Figure 2.WCDMA/TD-SCDMA Iub interface transport network layer is taked the IP option, provides possibility for Iub interface inserts the IP transmission network.But, this moment Iub interface the transmission group net mode not get rid of be the transmission network or even the ATM transmission network of E1 transparent transmission.
The transmission data owner that carries between base station and the base station controller will be divided into two kinds of the control signaling data relevant with wireless application and service signals, and service signal can be subdivided into voice service signal, low-speed data service signal and high-speed data service signal etc. again.Wherein, the voice service signal has requirement to real-time, and low speed/high-speed data service has non real-time and real-time two kinds of requirements, and in general, high-speed data service mostly is a non-real-time service, as browsing page, file in download etc.The transmission bandwidth that control signaling, speech and low speed real-time data service need take is less, but QoS indexs such as delay, shake and the error rate are had higher requirement; And the transmission bandwidth that most of high-speed data service need take is very big, but lower to the requirement of QoS indexs such as delay, shake and the error rate.
For convenience of description, this paper is divided into the secure and QoS of QoS with transmission network does not have and ensures two types.Wherein, the transmission network that the secure transmission network of QoS refers to postpone, QoS better performances such as shake and error rate and clock information can accurately be transmitted.The conventional secure transmission means of QoS comprises that microwave/local multiple spot distributes access service (Loeal Multipoint Distribute Service, be called for short " LMDS ")/PDH (Pseudo-synchronous Digital Hierarchy) (Plesiochronous Digital Hierarchy, be called for short " PDH ")/synchronous digital hierarchy (Synchronous Digital Hierarchy is called for short " SDH ") etc.The ATM transmission network also is carried on transmission such as the microwave/LMDS/PDH/SDH standard usually, therefore belongs to the secure transmission network of QoS.The transmission network that QoS poor-performing such as the transmission network that QoS does not have a guarantee refers to postpone, shake and the error rate and clock information possibly can't accurately be transmitted.Public IP transmission network generally is the transmission network that QoS does not have guarantee, and its QoS performance is generally lower, and the ratio that common public IP transmission network delay jitter is bigger, data-bag lost damages is higher.In general, do not have the cost of transmission network of guarantee than QoS high a lot of for the cost of the secure transmission network of QoS.
Because the RAN system when the initial stage of 3G network construction mostly is the ATM option of transport network layer employing 3GPP agreement regulation, be ATM RAN, the network construction form that Iub interface is taked is the secure transmission network of QoS basically, along with data service, particularly high speed data service such as HSDPA and user's growth, demand to high-speed data service can be more and more stronger, and pressing for this moment provides transmission group net solution between high-speed data service base station and base station controller cheaply.
Prior art scheme one all transmits all data of Iub interface on the secure transmission network of QoS.The system of prior art scheme one forms as shown in Figure 3.All data of this scheme Iub interface (comprising control signaling data and service signal) adopt the E1 transparent transmission or insert the ATM transmission network, use the secure microwave/PDH/SDH of QoS to transmit.When ATM RAN, generally all take the transmission group net scheme of technical scheme one, but persons of ordinary skill in the art may appreciate that the transmission group net scheme that when IP RAN, also can take technical scheme one.
Prior art scheme two does not all transmit all data of Iub interface on QoS has the transmission network of guarantee.The system of prior art scheme two forms as shown in Figure 4.All data of this scheme Iub interface (comprising control signaling data and service signal) are carried on the Ethernet (Ethernet), and the public IP transmission network of using QoS not have guarantee is transmitted.Can take this transmission group net scheme at IP RAN, and ATMRAN generally can't take this transmission group net scheme.
In actual applications, there is following problem in such scheme: the cost of prior art scheme one is too high, and can not the provide reliable service and the QoS of prior art scheme two ensure.
Cause the main cause of this situation to be, all data of prior art scheme one all adopt the secure transmission network carrying of the higher QoS of cost, when high-speed data service is provided, owing to need bandwidth very big, can bring very high transmission network cost.
Prior art scheme two uses QoS not have the transmission network of guarantee, therefore have that delay jitter is big, the defective of weak effect, qos requirement for voice service and real-time data service can't provide safeguard, in addition owing to can't ensure the transmission reliably in time of control signaling data, may cause defectives such as call drop, service disruption, reliable service can't be provided.
