The interface parameters collocation method of mobile communication system
Technical field
The present invention relates to moving communicating field, particularly the interface parameters configuring technical of Wideband Code Division Multiple Access (WCDMA) (Wideband CodeDivision Multiple Access is called for short " WCDMA ") communication system.
Background technology
As a focus of communications field development in recent years, 3G (Third Generation) Moblie (3rdGeneration is called for short " 3G ") has become the technology that the whole world is paid close attention to most, and is most important developing direction of preceding 10 years of 21 century.In the face of surpassing 1,000,000,000,000 dollars international market scale, 3G technology and product development are exactly the major subjects of each telecommunications company and research unit early also.Development according to the demand and the technology in market, (the International Telecommunication Union of International Telecommunications Union, being called for short " ITU ") 3G technology and standard just began one's study from 1986, and priority has been set up two International Standards Organization--3G co-operative project tissue (3rd Generation Partnership Project, be called for short " 3GPP ") and the 3G second co-operative project tissue (3rd Generation Partnership Project 2, abbreviation " 3GPP2 ") finish the detailed manuscript of formulating standard.To in May, 2000, ITU has formally determined with code division multiple access (Code Division Multiple Access, abbreviation " CDMA ") technology is that three standards of core are 3G global technology standard, Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access, be called for short " WCDMA ") technology just one of them, and continue to be responsible for perfect by 3GPP.
Be divided into R99, R4, R5 and the up-to-date several versions of R6 before the follow-up standard mesh of WCDMA that 3GPP works out, this a series of edition system frame diagram is similar substantially, its main characteristic is that land radio access web (Universal Terrestrial Radio Access Network is called for short " UTRAN ") adopts the WCDMA technology.As shown in Figure 1, core net 1 (Core Network is called for short " CN ") is divided into circuit domain 10 and packet domain 11, supports voice service and data service respectively.RNS 12 and the RNS 13 main aerial accesses of being responsible for the user, they link to each other with core net 1 with Iu interface 15 by Iu interface 14 respectively.Here need to prove, shown just among the figure that RNS 12 links to each other with circuit domain 10, in fact it also links to each other by another one Iu interface equally with packet domain 11, and RNS 13 situations are similar with it.RNS 12 inside have comprised radio network controller 120, base station 121, base station 122, and Iub interface 123 is respectively the interface of base station 121, base station 122 and radio network controller 120 with Iub interface 124.RNS 13 similar inside have also comprised radio network controller 130, base station 131, base station 132, and Iub interface 133 is respectively the interface of base station 131, base station 132 and radio network controller 130 with Iub interface 134.Between radio network controller 120 and radio network controller 130, also exist an Iur interface 16 to be used for the mutual of the two.Ellipse representation sub-district among the figure in the base station.
In the WCDMA system, Iub interface is with asynchronous transfer mode (Asynchronous TransferMode, abbreviation " ATM ") technology is as the agreement of the second layer, by the system framework figure of WCDMA as can be known, radio network controller (Radio Network Controller, be called for short " RNC ") move with base station (Node B) is normal, the connection of setting up ATM needs some common parameter between the two in full accord.These parameters comprise base stations control port (Node B Control Port, be called for short " NCP "), Communication Control port (Communication Control Port, be called for short " CCP "), Access Link Control Application Protocol (Access Link Control Application Protocol, be called for short " ALCAP "), ATM Adaptation Layer type 2 path (ATM Adaptation Layer type 2 PATH, be called for short " AAL2PATH "), atm address, (the Internet Protocol OverATM of interconnection protocol between the ATM bearer network, be called for short " IPOA ") maintenance channel, permanent virtual circuit (Permanent Virtual Circuit, abbreviation " PVC ") bandwidth or the like, above parameter is necessary setting up that ATM connects all, and these parameters are to be configured by the two Iub interface input.Have only RNC and Node B normally to move, the user just can enter the WCDMA system by air interface, could guarantee that the normal operation of whole WCDMA system gets up.This shows that the configuration of the common parameter of Iub interface is considerable.
In existing WCDMA realization system, the Iub interface agreement is made up of two functional layers with obvious differentiation: wireless network layer and transport layer.Therefore radio network signaling and Iub data flow and data transfer resource and professional processing distinguish.General wireless network layer regulation and the relevant program of Node B operation, form by wireless network control plane and wireless network user plane, the control plane of Iub and interface all adopts ATM Adaptation Layer type (ATM Adaptation Layer type 5, be called for short " AAL5 "), and user plane all adopts AAL2 on Iub interface.Transport layer is to have stipulated to set up between Node B and RNC the program that network connects, and each transmission channel all should have the AAL2 of a special use to connect.Be signaling or business data flow regardless of what transmit like this, all must on the ATM of RNC and Node B transmission adaptation layer, configure corresponding supplemental characteristic, so that set up the ATM passage.Because RNC and Node B generally are stand-alone developments separately, add that Iub interface is a common interface, as long as follow certain standard, the RNC of each producer and Node B can mixed networking.So configuration data information such as transport layer for RNC and NodeB, generally in engineering is used, the engineering staff who is RNC and Node B place carries out both sides' negotiation in advance, with the ATM passage relevant parameter of both sides' correspondence harmonious after, use portable machine or miscellaneous equipment more respectively at two places, be docked with local main frame, utilize the configuration software instrument on it to carry out data configuration, the Software tool here be research and development RNC and Node B two independently development group be two to overlap independently software basically according to separately situation establishment.So the engineering staff at RNC and Node B place is after the locality configures data, the data configuration file form of generation is inequality separately, and then downloads in separately the equipment and move.
In actual applications, there is following problem in such scheme: promptly the network planning of Commercial deployment is in large scale, when the building time span is very long, inconsistent situation can appear in the Iub interface both sides configuration data of RNC and Node B, thereby causes comprising conversation loss, the low inferior various strange phenomenons of data transmission rate.
Cause the main cause of this situation to be, the Iub interface common parameter configuration of adopting at present all is manually to adopt different Software tools separate configurations separately at RNC respectively with Node B place.
Specifically, network size when it come to arrives thousands of even several thousand base stations, the building time span reached more than 1 year, add network planning department in the construction period and often adjust some IPOA in the Iub interface or the common configuration data of sub-district (Cell) information, cause the often change of Iub interface common parameter of RNC and Node B in the network.So a large amount of base stations constantly advances in the process of construction, RNC and Node B will link up through repeatedly consulting common configuration data such as Iub interface transport layer and Cell information, and then meet the configuration data file of using separately according to result's generation of consulting.It is loaded down with trivial details uninteresting again that this process is actually, and the personnel at RNC and Node B two places must link up very in earnest for a long time and consult and the configuration data making.But engineering is used in the reality because personnel's carelessness or other details do not accomplish that will often make mistakes, inconsistent situation will appear in the common data of both sides' configuration of Iub interface.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of interface parameters collocation method of mobile communication system, can realize the consistent of base station and base station controller interface both sides configuration data, thereby reduce the low inferior problem of conversation loss, data transmission rate that causes thus.
For achieving the above object, the invention provides a kind of interface parameters collocation method of mobile communication system, comprise following steps:
A obtains base station and base station controller interface configuration parameter, and judges that this configuration parameter is common parameter, or the peculiar parameter separately of base station controller and base station, if common parameter then enters B, if peculiar parameter then enters C;
B by the common configuration data-interface, generates identical base station controller configuration order and the base station configuration order of parameter according to described common parameter, writes the configuration file of described base station controller and base station respectively;
C generates the base station controller or the base station configuration order of this parameter correspondence according to described peculiar parameter, and writes the configuration file of described base station controller or base station;
D moves corresponding configuration file respectively on described base station controller and base station.
Wherein, described configuration file uses the XML language.
The base station controller configuration order that is generated among the described step B is consistent in form with the base station configuration order.
In the described steps A, described configuration parameter is imported by graphic user interface by the operation user.
Described mobile communication system is the WCDMA system, and described base station controller is RNC, and described base station is a Node B.
By relatively finding, technical scheme difference with the prior art of the present invention is, the data configuration process of base station and base station controller is derived the configuration data file of each product respectively by an incorporate management system, and move corresponding configuration file respectively by base station and base station controller.
Difference on this technical scheme has brought comparatively significantly beneficial effect, has promptly guaranteed the consistency of each interface common data configuration, has reduced the generation of conversation loss, has improved data transmission rate.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
In order to overcome the prior art non-integral shortcoming of independent data configuration-system separately, the present invention adopts unified RAN data configuration management system to realize data configuration to the base station controller such as RNC and these two products of the base station such as Node B.This instrument has good graphic user interface, merged in the prior art RNC and the Node B place function of configuration software independently separately on the function, and than they two with better function, both can realize that the configuration of common datas such as Iub interface transport layer also can realize RNC and the Node B peculiar data configuration of product separately itself.RAN data configuration personnel only need a people to revise or configuration according to the needs of network planning part, after importing all configuration datas, by RAN data configuration management system generate two independently configuration file be respectively applied for RNC and Node B product, be RncCfg.xml, NodeBCfg.xml, these two configuration files by the write direct local host computer system of RNC or Node B of certain mode, just can make whole RNC system configuration finish respectively.
The integrated design of RAN data configuration management system, a people's operation can guarantee that the consistent of data configuration information of two products of RNC and Node B changes.Guaranteed the consistency of data configuration or modification from flow process.Avoid Node B and RNC in the past to use separately configuration-system to need both sides to consult to link up common data respectively and caused the problem of makeing mistakes easily, improved networking speed effectively, reduced maintenance cost.
Further describe below with regard to self result and function of RAN data configuration management system, and in conjunction with Fig. 2.
As shown in Figure 2, at first, in step 200, plan according to network organizing, the instruction of RAN data configuration personnel " establishment next node " is received by RAN data configuration management system, system generates the next or a plurality of Node B nodes of this RNC through after a series of planning algorithm computing, and with the graphical form networking graph of a relation that must demonstrate each product among the RAN directly perceived.Need to prove that the graph of a relation here generally shows as tree, promptly RNC is a root node, and Node B is a leaf node, and newly-generated Node B node can be marked in very eye-catching mode in the networking graph of a relation.
Next, in the step 210, RAN data configuration management system accepts the configuration data of RAN data configuration personnel input.
Step 220 subsequently is RAN data configuration management system deterministic processes to the input data, needs to judge that this configuration parameter is the common parameter of RNC and Node B node, still peculiar parameter separately.If common parameter then enters step 230, if the peculiar parameter of Node B then enters step 221, if the peculiar parameter of RNC then enters step 222.
In step 230, because having judged the data of reception is RNC and Node B common configuration data, so this system need carry out following processing to the data of input: pairing all the common data parameters in certain base station are imported or revised to data by the common configuration data-interface that system provides.Need to prove, thisly lead one and the moving mechanism of the overall situation, be to work out according to the Iub interface common parameter corresponding relation of RNC and Node B by system, when general native system uses, RAN data configuration personnel are in the place at the place of RNC, so the common parameter of input is except having influence on RNC, also to have influence on all Node Bs associated with RNC, compared with prior art, be equivalent to same RAN data configuration personnel in the scope of whole RAN to the input of Iub interface common parameter or revise, so guaranteed the common parameter unanimity that disposed.These common configuration data all are written to Node B and the RNC relevant position of configuration file separately at last.Those of ordinary skill in the art know, VCI (Virtual Path Identifier with the Iub interface NCP of certain Node B, be called for short " VPI ") and VPI (Virtual Channel Identifier, abbreviation " VCI ") is configured to example, because stipulating this parameter, atm technology needs that RNC is consistent with Node B just can to set up virtual connections, so native system receives RAN data configuration personnel and double-clicks in the graphical interfaces after this Iub interface line message, to eject " RAN common data configuration parameter " window, remind the configuration personnel toward wherein importing this VPI and VCI value, native system can write this type of public information the relevant position of NodeBCfg.xml and RncCfg.xml file simultaneously when these information of preservation.If it is middle because network planning change will be revised these parameters, by same individual corresponding N odeBCfg.xml and RncCfg.xml file are imported to make amendment and get final product, this moment is no matter revise these parameters in which file, all can allow and then change similarly of relevant parameter in the another one file.In fact two configuration files have here adopted extend markup language (eXtensible Marked Language is called for short " XML ") language, because of two orders that parameter modification generates can be the same in form in different configuration files.
In step 221, RAN data configuration management system receives the configuration personnel click this Node B node in graphical interfaces message, ejects " the peculiar configuration information of NodeB " page or leaf and reminds him to be provided with.Certainly at last native system only is written to the correspondence position of NodeBCfg.xml file with them when these information of preservation.Need to prove the not only configuration information of a Node B node that comprises in the NodeBCfg.xml file.
And in step 222, RAN data configuration management system receives the configuration personnel click this RNC node in graphical interfaces message, and corresponding ejection " the peculiar configuration information of RNC " page or leaf reminds him to be provided with.Native system can only be written to the correspondence position of RncCfg.xml file to them when these information of preservation equally at last.Need to prove that what comprise in the RncCfg.xml file usually is the Iub interface of the pairing current configuration of this RNC node and the RNC side data of radio layer.
At last, in sum, step 240, data configuration finishes, and the RAN configuration management system generates 2 kinds of configuration files, NodeBCfg.xml and RncCfg.xml.They are imported node corresponding just can make new configuration take-effective.After this will on Node B and RNC, move corresponding configuration file respectively.
Though by reference some preferred embodiment of the present invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that, can do various changes to it in the form and details, and the spirit and scope of the present invention that do not depart from appended claims and limited.
