Description
Technical field
The present invention relates to mobile communications network, be specifically related to the information transferring method between the base station and radio network controller in the communication network.
Background technology
In the networking of wireless communication system, NodeB and RNC (Radio Network Controller, radio network controller) the transmission network running cost between is the important component part of operator's operation cost, therefore the transmission network bandwidth utilance between NodeB and the RNC is subjected to the concern of operator deeply, and reasonable optimizing and the utilance that improves transmission bandwidth have great importance.
In the third generation wireless communication system, message transmission between NodeB and the RNC all adopts ATM (ASYNCHRONOUS TRANSFER MODE, asynchronous transfer mode) mode is carried out, and wherein RNC is to safeguard by the OM channel that IPOA (IP overATM) mode is set up to management information and the control information (Operation and Maintenance information) of NodeB.The information that transmits by OM channel comprises: the configuration order that is handed down to NodeB, report the normal discharge information such as NodeB alarm information of webmaster, and the burst flow information such as software kit, abnormality alarming information and alarm windstorm that when base station software is upgraded, are handed down to NodeB.
For OM channel, the daily normal discharge of network is very little, only need the bandwidth of tens Kbps, and when transmitting the burst flow that causes owing to reasons such as NodeB software automatic updatings, the bandwidth that generally requires OM channel is about 1Mbps to tens Kbps.
Transmission of Information all is by PVC (Permanent Virtual Circuit in the OM channel, water virtual circuit of a specified duration) carries, the PVC loaded service can be divided into CBR (Constant Bit Rate, constant bit rate), VBR (Variable Bit Rate, variable bit rate service), UBR (UnspecifiedBit Rate, nonspecific bit rate service), ABR types such as (Available Bit Rate, available bit rates).OM channel is at the attribute assignment bandwidth of the type of service of PVC setting.
The transmission of Information method is between a kind of base station of the prior art and the radio network controller: the type of service of PVC is set to the CBR business, and promptly OM channel is arranged to fixed value with bandwidth all the time.Concrete method to set up is a kind of to be according to the required bandwidth of normal discharge, and bandwidth is arranged to tens Kbps; Another kind is that bandwidth is set to about 1Mbps according to the required bandwidth of burst flow, and Operation and Maintenance information is transmitted in the fixed-bandwidth that presets.
But the problem that this method exists in message transmission is: if bandwidth is arranged to the required bandwidth of normal discharge, then message transmission overlong time during burst flow causes the difficulty of NodeB software upgrading to increase; If bandwidth is arranged to 1Mbps, though the transmission of Information time can shorten burst flow the time, because the flow of Operation and Maintenance information seldom will cause the waste of transfer resource at ordinary times.
Information transferring method in the prior art between another kind of base station and the radio network controller is: PVC is set to the VBR business, and its cell Mean Speed SCR of corresponding setting and Peak Cell Rate PCR.During routine work, OM channel is the bandwidth of Operation and Maintenance information distribution SCR, and OM channel allows information to transmit in the bandwidth of PCR when burst flow.
But because the VBR business has certain promise to service quality QOS (QoS parameter), when the business burst transmission quantity is very big, in order to guarantee professional QOS, the cell that needs in time to send temporarily is stored in buffer area, absolute difference between SCR and PCR is big more, expression burst transfer amount is big more, the buffer area capacity that needs is big more, and be limited as the chip capacity of the equipment of buffer area, therefore, must increase new equipment in order to increase buffer pool size, and the equipment increase will cause operation cost to raise.Because OM channel normal discharge and burst flow difference are very big, improve bandwidth availability ratio when therefore adopting the mode of VBR can not solve message transmission in the OM channel preferably and shorten the problem in big flow information transmission time.
Summary of the invention
The technical problem to be solved in the present invention is: the information transferring method between a kind of base station and the radio network controller is provided, improves bandwidth availability ratio in the time of can solving message transmission and shorten the contradiction of big flow information between the transmission time.
For this reason, the invention provides the method for message transmission between a kind of base station and the radio network controller, be used to transmit the Operation and Maintenance information of OM channel, comprise step:
1) configuration VPI and VCI are set up PVC;
2) type of service of described PVC is set to nonspecific bit rate service;
3) QoS parameter and IP address argument are set, set up OM channel;
4) utilize described OM channel to transmit Operation and Maintenance information, and start ftp server during more than or equal to the Operation and Maintenance information of scheduled transmission speed in transmission rate according to described nonspecific bit rate service mode.
Wherein said QoS parameter comprises Peak Cell Rate, and described scheduled transmission speed is described Peak Cell Rate.
Wherein, described transmission rate is a software kit information more than or equal to the Operation and Maintenance information of scheduled transmission speed.
Wherein, described nonspecific bit rate service mode is transmitted and is specially: transmission rate is transmitted according to transmission rate less than the described Operation and Maintenance information of described Peak Cell Rate; Otherwise, according to described Peak Cell Rate transmission.
In addition, described nonspecific bit rate service mode transmit can also for: when the idle bandwidth of described OM channel during more than or equal to described Peak Cell Rate, with the described Operation and Maintenance information of the speed rates that is less than or equal to described Peak Cell Rate; When the idle bandwidth of described OM channel during less than described Peak Cell Rate, with the described Operation and Maintenance information of the speed rates that is less than or equal to the OM channel idle bandwidth.
Compared with prior art, the invention has the beneficial effects as follows: be set to UBR because the type of service of the PVC PVC of Operation and Maintenance information is carried in the present invention, make OM channel when normal discharge, can distribute bandwidth, thereby improved bandwidth availability ratio according to information self transmission rate; During burst flow, distribute bandwidth according to Peak Cell Rate, because UBR allows to be provided with bigger Peak Cell Rate, therefore, the transmission of Information time when having shortened burst flow; Simultaneously, QOS is not promised to undertake, when flow is excessive, cell is made discard processing owing to UBR service, the service quality of the present invention when guaranteeing software download, when the transmitting software bag, adopt ftp server to transmit, the packet loss problem of having avoided simple use UBR to cause.From the above mentioned, use the present invention, not only fully improved bandwidth utilization, transmission of Information time when having shortened burst flow, and needn't increase new hardware, thereby solved bandwidth availability ratio and the contradiction of message transmission between the time in the OM channel.

Embodiment
The present invention puts forward in order to save the shared bandwidth resources of OM channel.
In the 3G network, transmission of Information adopts the mode of ATM to carry out between NodeB and RNC.ATM is the fast packet switching technology that grows up on packet-switch technology, and its maximum characteristics are assurances (QOS) that service quality is arranged.Because atm network mostly is to be used as real-time Transmission, therefore must satisfy certain service quality, transmission of Information is all carried by PVC PVC in the atm network, before setting up a PVC, transport layer and atm network layer all will be observed the agreement of a definition service, formulate type of service, select and professional relevant QoS parameter, both sides formulate relevant QoS parameter through consultation, specify in the numerical value that requires the communication supplier to reach or to surpass under the worst condition.
The service quality of ATM is divided following four kinds of grades of service: constant bit rate CBR business, real-time variable bit rate RT-VBR business, Non-Real Time Variable Bit Rate NRT-VBR, nonspecific bit rate UBR service.
The CBR business characteristic is to have timing relationship towards connecting, having between fixed bit rate, the communication end point.The Peak Cell Rate PCR that can continue in whole connection procedure transmits, and portable terminal can be at any time, transmit with the cell rate that is equal to or less than PCR in the arbitrary period.Be mainly used in the connection that needs fixed-bandwidth.
The RT-VBR business features is towards connection, and bit rate is variable, has timing relationship between the communication end point.The bandwidth that communication end point takies changes with end message transmission rate in the different time, and atm network gives the assurance of SCR to communication terminal, requires communication terminal to send information greater than the speed of Peak Cell Rate PCR simultaneously.The RT-VBR business mainly is to be applied to the business strict to time sensitivity (needing strict time delay and time delay political reform).
The NRT-VBR business features is towards connection, and bit rate is variable, does not have timing relationship between the communication end point.The bandwidth that communication end point takies changes with the rate variation that end message in the different time sends, and atm network gives the assurance of SCR to communication terminal, and the speed PRC that requires communication terminal to be not more than Peak Cell Rate simultaneously sends information.The professional main application of NRT-VBR is paroxysmal to change the undemanding business that requires to time delay and time delay.
The UBR service characteristics are towards connection, and bit rate is variable, and the bandwidth that communication end point takies changes with the variation of end message transmission rate and available bandwidth in the different time.The speed that atm network requires communication terminal to be not more than Peak Cell Rate (PCR) sends information.UBR does not commit oneself in any way to QOS, does not feed back congested yet, and is different with VBR, if take place congestedly, the UBR cell that has little time to send can not be buffered, but directly is dropped, and do not send feedback to the sender, do not wish expectation slowly to the sender yet.It is big that UBR is suitable for rate variation, to the less demanding business of QOS.
RNC safeguards by IPOA management and the control information (Operation and Maintenance information) of NodeB.The present invention consider since the business characteristic of OM channel to be at ordinary times normal discharge occupied bandwidth very little, the bandwidth that burst flow requires is very big, be the very big characteristics of rate variation, the type of service of PVC is set to UBR service, and the concrete configuration process is as described below.
The type of service of the PVC PVC of RNC side and NodeB side is set to nonspecific bit rate service UBR before setting up PVC PVC, consult relevant QoS parameter with operator then, for UBR, the QoS parameter that needs to consider is Peak Cell Rate PCR; After above-mentioned parameter manually consults, on RNC and NodeB, be provided with respectively, finish the foundation of PVC PVC; If the configuration of complete operation maintenance channel also needs the IP address of NodeB and RNC is configured, so far, the foundation of complete operation maintenance channel; When the parameter of utilizing the present invention to dispose is carried out message transmission, OM channel is safeguarded with the characteristics of communicating by letter of end message transmission rate in the different time and available bandwidth dynamic bandwidth allocation according to the bandwidth that UBR service takies, when the information flow-rate of base station controller transmission is not more than the Peak Cell Rate PCR of setting, according to the original speed rates of information flow-rate; When the speed of information flow-rate surpassed Peak Cell Rate, the maximum rate that allows to pass through according to OM channel was that Peak Cell Rate PCR transmits, and where necessary base station node B is connected with File Transfer Protocol with radio network controller (RNC).
Below introduce the operation principle that each step relates in detail.
1, the foundation of PVC.
Transmission of Information is all carried by PVC PVC in the atm network, therefore, when the message transmission of carrying out between base station and the radio network controller, at first needs to set up PVC.When setting up PVC, the configuration PVC PVC of the operation maintenance center sign by the base station controller end: Virtual Channel and VCI (VPI/VCI), VPI/VCI are the signs of each ATM cell., each network node all can judge cell, according to different VPI/VCI with ATM cell along network from the source end (being the base station controller end) move towards destination (base station) or opposite (delivering to RNC) from the base station.The ATM cell that VPI/VCI is identical belongs to same PVC, and the cell with identical VPI/VCI sign will be sent to same address.
The foundation of finishing PVC also needs to dispose the related service parameter under the set type of service, because preceding base station of configuration and base station controller both sides have decided through consultation that the type of service of PVC is nonspecific bit rate service UBR, therefore associated parameter only has Peak Cell Rate PCR, dispose Peak Cell Rate PCR respectively at configurating base station and side of base station controller, finish the foundation of PVC.
2, the foundation of OM channel.
Then, in base station and base station controller both sides configuration of IP address parameter, between base station and base station controller, set up OM channel respectively.
Base station controller is divided into normal discharge and burst flow by the Operation and Maintenance information that OM channel sends, normal discharge is meant the configuration order that is handed down to NodeB when working at ordinary times by OM channel, report the NodeB alarm information of webmaster, the modal situation of burst flow is handed down to the software kit of NodeB when being the base station software upgrading.When carrying out message transmission, the present invention is directed to the different needs of user to different burst flows, carry out differentiated treatment, when process software is downloaded the burst flow that causes, start ftp server, the quality of guarantee information transmission.
It below is the specific embodiment of information transferring method of the present invention.
Embodiment: the process of setting up OM channel is as indicated above, does not repeat them here.After setting up OM channel according to the method described above, just the message transmission between base station controller and the base station can have been carried out.Characteristic according to nonspecific bit rate service UBR itself, when working at ordinary times, when the transmission base station controller is handed down to the configuration order of NodeB and NodeB alarm information that the base station reports webmaster by OM channel, because normal discharge is very little, tens Kpbs is generally only arranged, therefore, OM channel allows normal discharge to transmit according to the bandwidth that self needs, for example, when transmitting the configuration order of 10Kpbs, OM channel will distribute the bandwidth of 10Kpbs; Software download is a situation the most common in the burst flow, when base station controller need be downloaded the upgrade software bag of NodeB to the base station, OM channel will reserve the bandwidth that is not less than the Peak Cell Rate that sets, but because UBR is very big in service traffics, take place when congested, the characteristics that the UBR cell that can will have little time to send directly abandons, in order to guarantee transmission quality, considering that in software download be under the prerequisite of non-real-time service, the present invention adopts File Transfer Protocol, to guarantee the correctness of file transfer.
Fig. 1 is the flow chart of first embodiment of the invention.As shown in the figure:
At first, safeguard before the configuration that end and operator manually consult PVC type of service, PVC parameter, guarantee the consistency (step 1) of NodeB, RNC two ends parameter;
Then, by the PVC parameter (step 2) of configuration platform configuration RNC, NodeB side, different professional corresponding different QoS parameters for the VBR business, must the configured QOS parameter comprise: PCR, SCR, MBS respectively; For UBR service, the QoS parameter that must dispose is only considered Peak Cell Rate PCR, the bandwidth in the time of PCR can being arranged to download software about general required 1Mbps.And with SCR and MBS as optional parameters, if desired, the SCR that can carry the PVC of Operation and Maintenance information is set to tens Kbps, MBS can be arranged to 1000～10000 ATM cell;
On RNC, dispose route, be communicated with the IP tunnel (step 3) between RNC and NodeB;
Step 4, set up OM channel after, OM channel will be according to the distribution bandwidth of the change dynamics of Operation and Maintenance information transmission rate in the different time and passage available bandwidth.At ordinary times OM channel is carried out normal Operation and Maintenance, as transmitting order to lower levels, report and alarm etc.
When the needs software download, on the OMC of operation maintenance center of RNC, start FTP Server program, assign instruction by OMC to NodeB, set up FTP passage (step 5);
After NodeB receives instruction, reserve the bandwidth of PCR (step 6) at least, for quick upgrading, can interrupt some business, or directly when business is fewer, upgrade for downloading software;
Step 7 downloads software to NodeB by File Transfer Protocol.
In downloading process, the transmitting terminal of FTP indication file is divided into packet with file and transmits, and increase check code at each packet, mode by IPoA is mapped to ATM cell with each packet then, each packet at first needs the ATM cell of different numbers to carry, and then on physical link, transmit, might be in the physical link transmission course because the quality and the bandwidth problem of physical link cause error code or ATM cell to abandon, thereby cause the imperfect of packet, the receiving terminal of file judges according to the check code of each packet whether the packet that receives is complete, correctly, if packet is wrong or partial loss, then require transmitting terminal to retransmit, thereby guaranteed the correctness of file in download transmission.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
