Description

Be used for method and communication system in the supervising the network processing parameter variation of cellular communication system
Technical field
The present invention relates to be used for the method and the communication system that change at the supervising the network processing parameter, wherein said supervising the network is used for cellular communication system is carried out network monitoring and control, wherein said supervising the network comprises as the equipment in the different management level, at least two managers and at least two agencies, wherein between at least one first agency of first manager of network device management layer and network equipment layer, there is at least one first manager-agent relation, wherein have at least one second manager-agent relation between at least one second agency of second manager of NML and described network device management layer, wherein parameter of at least one first agency of relevant described network equipment layer is changed.
The invention still further relates to a kind of communication system, this communication system has the supervising the network that is used for cellular communication system is carried out network monitoring and control, comprise as the equipment in the different management level, at least two managers and at least two agencies, wherein between at least one first agency of first manager of network device management layer and network equipment layer, there is at least one first manager-agent relation, wherein existence at least one second manager-agent relation between at least one second agency of second manager of NML and described network device management layer.
Background technology
The principle of supervising the network is also referred to as TMN principle (TMN:TelecommunicationsManagement Network, telecommunication management network), it has defined a plurality of management level to be used for supervisory communications, for example mobile communication system, and wherein each layer all has dual-use function except uppermost layer and nethermost layer.In management system (" managing system "), except nethermost layer, each layer all is that the layer that is positioned under it is exercised Manager Feature.By in the system (" managed system ") that manages, except uppermost layer, each layer all is the higher level function of acting as agent.
The ITU-T standard of series of X .73x is that the management of communication network has defined different " system management function (Systems Management Functions) ", and these system management functions can be used by application process in the management environment of concentrating or disperse.
Manager-agent communication is undertaken by so-called management interface or manager-proxy interface, described interface can pass through communication protocol in OO environment (for example (CommonManagement Information Protocol nach ITU-T X.711 for CMIP, according to ITU-T CMIP X.711) or CORBA (Common Object Request BrokerArchitecture, common object request broker architecture)) and object model identify.
This interface for example is present between network device management layer (Network Element ManagementLevel) and the network equipment layer (Network Element Level).Example to the network equipment of this interface (OMC-BSS interface) for example is operation and maintenance centre (OMC Operationand Maintenance Center) in described network device management layer (NetworkElement Management Level) side, and for example is the base station of for example base station system (BSS BaseStation System) in the GSM mobile radio telephone network in described network equipment layer (Network ElementLevel) side.For example mention the base station of second generation GSM network at this.The base station that also can relate to other communication systems within the scope of the invention, for example the Node B of UMTS mobile radio telephone network (UMTS Universal Mobile Telecommunication System, Universal Mobile Telecommunications System).
Yet described interface also for example is present between NML (Network ManagementLevel) and the network device management layer (Network Element Management Level).To the example of the network equipment of this interface (NMC-OMC interface) for example is network management center (MNC Network Management Center) in described NML (Network Management Level) side in described GSM or other mobile radio telephone network for example, and for example is described operation and maintenance centre (OMC Operation and Maintenance Center) in described network device management layer (Network Element Management Level) side.
Configuration management (CM Configuration Management) relates to one to five so-called management function zone (" Management Functional Area "), the TMN principle of these management function area identification supervising the networks.Described configuration management has defined a series of business (services), and these business can realize changing the structure of communication network and therefore changing its characteristic by operator.These business always relate to the entity of the object (Managed Object) managed, these entities carry out modeling to Internet resources in OO environment, and constitute the specific management information base of network (MIB Management Informat ion Base) generally.
Honeycomb is a kind of basic principle that is used to dispose the radio subsystem of mobile radio telephone network.The prerequisite of the function of mobile radio telephone network is the correct definition to the relation between the neighbor cell (" adjacent cells ").
From the angle of " management information ", this relation defines by two kinds of object type in principle:
Sub-district (Cell): (reference) sub-district in the substantial definition mobile radio telephone network of this object type of being managed (MOC Managed Object Class).
Neighbor cell (AdjacentCell): the substantial definition neighbor cell of this object type of being managed (MOC), described neighbor cell can be used to switch purpose and/or reselect purpose with respect to described reference cell.
For " mobility " managed, by network planning system ( NEtwork PLanning SYstem, NPS) trans-regional ground and determine neighbouring relations and relevant therewith parameter (for example bCCHFrequency, synchronized, hoMargin, rxLevMinCell) in network range, wherein said network planning system guarantees the correctness and the consistency of described honeycomb.
By this network planning system and by realizing the introduction of first configuration and realize big configuration change (referring to following Fig. 1) to the file interface of OMC particular network planning instrument.Described network planning tool is provided according to the specific parameter of manufacturer by the coupling of the new configuration data that is provided by described network planning system.Corresponding operation and maintenance centre (OMC) are responsible for the configuration of the all-network unit (NE) in its network area.
Employing with described network planning system of network planning tool guarantees correct network configuration at any time, but has big shortcoming, and promptly it is expensive, and normally inapplicable for the simple change of single configuration parameter.In daily network management practice, always there is such situation again, network configuration and/or network parameter in these situations (wherein also having the neighbouring relations between the sub-district) should be changed in short time by operator:
Utilize local maintenance equipment (LMT Local Maintenance Terminal) at the scene, described local maintenance equipment can be connected to the different network equipment (for example net control device (BSC base station controller or RNC radio network controller)) and go up (further meaning: (NE) changes parameter by local network element)
On OMC, go up (further meaning: change parameter) in " network element management level " by regional OMC.As mentioned above, from the angle of management, OMC comprises 2 logical gates: NE manager (being used for the OMC-NE interface) and NMC agency (being used for the OMC-NMC interface).
The configuration change that this need are manually implemented is a critical operations, because can influence " switching " and/or " reselecting " process.Owing to can only in the environment in trans-regional, the network range, correctly check the change of radio parameter, so perhaps just wrong in this point or inadequate operator input has great negative consequences to the characteristic of whole mobile radio telephone network.
A kind of communication network with a plurality of network areas has been described among document DE 199 47 083 A1, in this communication network, the command file that is independent of the grammatical form of network area is transferred to OMC by NMC, described afterwards OMC is converted to the specific script file in network area to described command file, and it is transferred to network element.
Document EP 0 348 331 A2 have described a kind of communication network, and each node all has the tabulation of its Internet resources of topological database form in this communication network.If the state of this Internet resources changes, so described node just sends to its adjacent node to the topological database that is modified.
Be used for to the supervising the network that cellular communication system carries out network monitoring and control comprise as the equipment of different management level, at least two managers and at least two agencies, wherein between at least one first agency of first manager of network device management layer and network equipment layer, there is at least one first manager-agent relation, and wherein between at least one second agency of second manager of NML and described network device management layer, has at least one second manager-agent relation.Here investigate following situation: change parameter about at least one first agency of described network equipment layer.
As long as the configuration change of manually being implemented by local operator relates to such sub-district, the neighbor cell of this sub-district (adjacent cells) is positioned at identical (being monitored by same OMC) network area, and parameter change is known by described operation and maintenance centre (OMC) in all neighbor cells usually usually immediately so.
Yet the sub-district in the edge that is arranged in the network area, parameter change are problems.Because these sub-districts are the neighbor cell of the reference cell in other network area simultaneously, this means, it is monitored by one or more other operation and maintenance centre (OMC), so this change also must become effectively under not free situation about postponing in adjacent network area, so that can guarantee data consistency in whole network.Otherwise have big danger, promptly " switching " and " sub-district is reselected " mechanism is carried out not correctly, and the conversation of mobile radio users is lost.
In current system, the form of each OMC operator management so-called " external cell (foreigncells) " (from other regional neighbor cells), this form is important for " switching " and " reselecting " process.Must will be for example the parameter change notification of " external cell " in zone give other operator in the adjacent area, these operators manually change relevant parameters subsequently.Under the situation that communication goes wrong or mistake is imported, in adjacent network area, be easy to generate inconsistency at this.
