Embodiment
Among the present invention, the network resources model (NRM, NetworkResource Model) of setting up pond group MSC/SGSN Pool is the prerequisite of NMS to its management, simultaneously also will be on the basis of this resource model to its be managed for configuration, performance management and fault management.
The network resources model that utilizes object-oriented method to set up comprises two aspects, be the object relationship figure (relation between description object) of Internet resources on the one hand, be the information model (the various configuration parameters and the performance parameter of description object, the i.e. feature of object) of Internet resources on the other hand.Because at present the object instance of managed element is substantially all realized at EMS, thus the present invention is based on the network resources model that EMS sets up pond group MSC/SGSN Pool, and at the pond group objects Msc/SgsnPoolFunction of EMS instantiation pond group MSC/SGSN Pool.At pond group MSC/SGSN Pool, its object oriented programming model in the network resources model of network management system inclusion relation and inheritance as shown in Figure 3, Figure 4.
Among Fig. 3, pond group objects class Msc/SgsnPool Function realizes all logic functions of pond group MSC/SGSN Pool function, it is the part of object class SubNetWork in the network management system, may comprise 0 to a plurality of Msc/SgsnPool Function among 1 SubNetWork, and 1 Msc/SgsnPoolFunction only belongs to 1 SubNetWork.Object class Msc/Sgsn Function is network element MSCServer/SGSN (Mobile service Switching Centre Server/Serving GPRS SupportNode, the mobile switching center's servers/services GPRS Support Node of serving) object model, 1 pond group objects Msc/SgsnPool Function forms to a plurality of Msc/Sgsn Function by 1.Fig. 4 has illustrated the inheritance of pond group objects class Msc/SgsnPool Function from the Top object class.In the network resources model of network management system and the relation between other object class, network management system can realize its configuration management, performance management and fault management based on pond group objects class Msc/SgsnPool Function.
The pond main configuration parameter of group MSC/SGSN Pool is as follows, i.e. the configuration attribute of Msc/SgsnPool Function:
● MSC/SGSN Pool identifier: the name attribute of this object, this Pool of unique identification in overall core net;
● MSC/SGSN Pool numbering: for ease of management, for each MSC/SGSN Pool provides a numbering (this is optional);
● MSC Server/SGSN overall situation core net identification list: the tabulation of MSC/SGSN Pool unique identification network element MSC Server/SGSN in core net;
● NRI (Network Resource Identifier, network resource identifier) tabulation: the MSC Server/SGSN information list of MSC/SGSNPool management should be a structure that comprises MSC Server/SGSN essential information;
● NRI Length:NRI is shared length N RI length in TMSI (Temporary Mobile Subscriber Identity, temporary mobile subscriber identity);
● Null NRI tabulation: indication BSC/RNC (Base Station Controller/Radio NetworkController when being used in the MSC/SGSN Pool between MSC Server/SGSN the processing of migrated users, base station controller/radio network controller) is MS (Mobile Station, travelling carriage) or UE (User Equipment, terminal) reselect a MSCServer/SGSN that can serve;
● the non-broadcasting LAI/RAI of each network element (Location Area Identity/Routing Area Identity among the Non-broadcast LAI/RAI:MSC/SGSN Pool, use when Location Area Identification/Routing Area Identifier), this parameter is carried out load balancing in system (concrete use can referring to 3GPPTS 23.003).
Pond group objects Msc/SgsnPool Function can utilize the Notification Method of the object of traditional network element to send notice to upper layer NMS: the Object Creation notice, object deletion notice, the object properties value changes notice, the acknowledged alarm state changes notice, the alarm notification that changes, the alarm notification of removing, new alarm notification.
The performance parameter of pond group objects Msc/SgsnPool Function is different from each independent network element of present network management system management, so provide following explanation earlier:
Because MSC/SGSN Pool does as a wholely externally to present,, embody the whole service operation situation of Pool so the statistics of the Pool overall situation need be provided.Because when adopting MSC/SGSN Pool networking, each MSC Server/SGSN serves all BSC/RNC in the district of pond in the group of pond, promptly BSC/RNC belongs among the identical tanks group MSC/SGSN Pool.For example, in Fig. 1, MSC1, MSC2 and MSC3 have formed a pond group MSC Pool, so MSC1, MSC2 and MSC3 serve RAN nodes all in the CS-Pool zone 1, pond district, RAN node in promptly regional 1, regional 2, regional 5 and regional 6, in other words, the BSC/RNC in zone 1, zone 2, zone 5 and the zone 6 belongs among the pond group MSC Pool of MSC1, MSC2 and MSC3 composition.Some performance index of so original stand-alone network elements MSC Server/SGSN no longer have global sense, can't embody the complete service operation situation in concrete zone (as certain route district), the statistics that needs to be dispersed in same class measurement item on each network element when therefore pond group performance parameter is obtained gathers on EMS, obtains having the statistics of overall reference significance.
Because the pond group is made up of a plurality of network elements, so the performance parameter of pond group MSC/SGSN Pool can be divided into from the statistics angle: (for example measure the subitem rank, a route district), the network element rank (for example, the network element MSC Server of Chi Zuzhong) and pond group rank (for example, at a pond group SGSN Pool), its implication is as follows respectively:
A) measure the subitem rank: the data of the identical measurement subitem of different network elements in the MSC/SGSN Pool are gathered.For example, at a SGSN Pool who forms by SGSN1, SGSN2 among Fig. 1, suppose to have three route districts, be respectively route district 1, route district 2 and route district 3, measure subitem---the activation number of times in route district 1 if calculate, then its computing formula is: the activation number of times of the activation number of times of the activation number of times of route district 1 (all)=route district 1 (on SGSN1)+route district 1 (on SGSN2);
B) network element rank: of a sort all measurement item numbers certificates of a MSC Server/SGSN network element in the MSC/SGSN Pool are gathered.For example, at a SGSN Pool who forms by SGSN1, SGSN2 among Fig. 1, suppose to have 3 route districts, if calculate a network element---the activation number of times of activation number of times+route district 3 (on the SGSN1) of activation number of times+route district 2 (on the SGSN1) of the activation number of times of SGSN1: SGSN1 activation number of times=route district 1 (on SGSN1);
C) pond group rank: the same class data of all MSC Server/SGSN network elements in the pond group MSC/SGSN Pool are aggregated into the Pool rank.For example, at a SGSN Pool who forms by SGSN1, SGSN2 among Fig. 1, the activation number of times of activation number of times+SGSN2 of the activation number of times=SGSN1 of its pond group level.
Therefore, when pond group MSC/SGSN Pool performance parameter is added up, because the correlative measurement quantifier of MSC/SGSN (is measured an x1 for n that establishes MSC/SGSN in MSC/SGSN Pool performance parameter (performance parameter of establishing MSC/SGSN Pool is y) and the pond group, x2,, have functional relation y=f (x1, x2 between xn), xn), so EMS need be according to these functional relations y=f (x1, x2,, xn) can draw the performance parameter of pond group.
Simultaneously, EMS provides pond group MSC/SGSN Pool alarm monitoring function, and the alarm notification that MSC/SGSN Pool is relevant mainly comprises unbalanced fault warning of load and the inconsistent event notice of data.
When in the MSC/SGSN Pool between MSC Server/SGSN load the highest with the minimum difference of load when reaching preset threshold, EMS produces the unbalanced alarm of load, when difference value was lower than threshold value, alarm can recover automatically.
When carrying out the inspection of periodicity automaticdata, to in the MSC/SGSN Pool and the inconsistent phenomenon of the data that exist between the MSCServer/SGSN network element (for example, owing to reasons such as network management system startup, communication cause the real data of pond group side and network element side inconsistent), for according to the correct judgement of alarm network operation situation, just need EMS can produce the events corresponding notice.
The user by multiple querying condition is set, can find MSC/SGSN Pool relevant current alarm and event notice, so that carry out network operation work fast on EMS.
Pond group MSC/SGSN Pool is being carried out on the basis of modeling, just can carry out, below the pond group management apparatus and the concrete course of work thereof are being introduced its management.
Fig. 5 has shown the pond group management apparatus schematic diagram of realizing at EMS/OMC, comprises Configuration Manager, performance management module, and fault management module.
Configuration Manager is mainly finished the parameter configuration to the pond group, it comprises pond group objects configuration and two functional units of related network elements configuration, pond group objects configuration feature assembly is mainly finished the parameter configuration of pond group objects example, related network elements configuration feature assembly is mainly finished when carrying out the pond configuration set, configuration to the relevant parameter of RNC, MGW (MediaGateway, media gateway), MSC Server, SGSN.
Performance management module is mainly finished the performance management to the pond group, promptly obtains the performance of pond group, and it comprises that pond group performance data is calculated and the network element performance data is collected two functional units.Mapping relations between pond group performance data computing function assembly main storage pool group performance data and the network element performance data, and utilize mapping relations computing pool group performance data; The network element performance data is collected the collection of mainly finishing the performance data of network element in the group of pond, and collection can be passed through two approach, and an approach is direct acquisition network element data, and another approach is to obtain its performance data from the EMS object instance of network element.
Fault management module is mainly finished the fault management to the pond group, and it comprises pond group fault management and two functional units of network element failure management.Pond group fault management is primarily aimed at the fault of pond group objects self and carries out fault alarm and fault alarm elimination untill further notice to Upper NM Station; The network element failure management is to carry out fault alarm and fault alarm elimination untill further notice at the fault of the network element related with the pond group to Upper NM Station.
