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.
Upgrade maintenance demand at electronic information, especially various different base station equipment forms and development requirement in the mobile communication, a kind of software subsystem framework need be provided, can be based on various system resource operations, realize that higher layer applications upwards provides service, as realizing mobile communication protocol function etc.In view of this, the software design framework that the present invention proposes, by separately realization of two parts is handled in system resource management and higher layer applications, adopt resource management object mode descriptive system resource, improve the reusability and the maintainability of software code, guarantee the stability and the reliability of software systems simultaneously, because the new base station form of research and development or realize the workload of new demand, improve the quality of products, reduce cost of products, raising response speed market to reduce.
With the example of base station sub-system in the 3-G (Generation Three mobile communication system), software subsystem scheme of the present invention is described in detail below as electronic information.The system resource that base station system possesses has hardware resource, logical resource, the application service of required realization then is the function of 3G (Third Generation) Moblie partner program (3rd Generation Partnership Project is called for short " 3GPP ") protocol specification regulation.Hardware resource is such as having processor, veneer, digital circuit blocks, storage space, base-band resource, band resource etc., and logical resource is then as identification number assignment resource, variable name space etc.And the service that need provide is such as being the access conversation to transfer table, the control etc. of eating dishes without rice or wine.
Handle invention thinking separately according to resource management and application, the framework of software subsystem as shown in Figure 1 in the first embodiment of the present invention.Comprising upper two layers, for use handling (Application is called for short " APP ") layer, also is the realization of agreement flow process above, is used for based on the request of system resource process user, realizes higher layer applications, upwards provides service; Be resource management layer below, be used for management, scheduling, maintenance system resource, and provide the resource transfer interactive interface, wherein need device driver for physical resource or hardware resource to described application processing layer.
The application processing or the agreement flow process of base station system generally all realize according to the 3GPP protocol specification, and agreement self the change cycle is longer relatively, in quite long market cycle, the change of agreement and renewal upgrading all are slow, therefore even if comprehensive renewal that protocol update generally also can be accompanied by equipment occurs, what use that the realization of processing layer more need consider is reusability, versatility and the inheritance of code but not the property upgraded.So the first embodiment of the present invention with metastable, higher this part of inheritance versatility requirement brought into the application layer part, directly realize by code development, all general after exploitation is finished for all types of base stations, reduce cost of development relatively.
Relatively and protocol specification, it is faster more frequent that base station modal alteration, HardwareUpgring or safeguard changes, and causes the software subsystem development workload to be greatly in the physics of device drives, change to change equipment or code research and development that logical resource is handled and the testing authentication thus.Therefore, the present invention concentrates on the resource management layer realization with contents such as the resource management relevant with apparatus system resource, description, configurations.By providing unified interface to carry out alternately, realize higher layer applications calling or the status message notice of resource between two-layer to underlying resource to using.
As seen by the division of two-tier system, make software subsystem code and configuration be divided into and relevant two parts irrelevant, focus on the raising of inheritance, versatility and reusability, maintainability respectively with resource.To continue below with the base station sub-system is how example explanation realizes resource management layer and to last interface, and uses processing layer or agreement flow process etc. as long as realize by concrete agreement, and the interface that meets resource management layer and provide gets final product, and no longer illustrates.
Design for resource management layer, the characteristics of finding out this layer easily are centralized management, maintenance, the renewal of resource, continue to use the Object-Oriented Design thinking of higher level lanquage, the second embodiment of the present invention is on the basis of first embodiment, adopt the management of object-oriented way realization in resource management layer to system resource, promptly use uniform resource management Format Object package system resource, be called resource management object (ManagedObject is called for short " MO ").And each MO includes numerous relevant member properties, such as the information of resource itself, is called management object information (Managed Object Information is called for short " MOInfo "); Relation between the resource is called management object relation (Managed Object Relation is called for short " MORela "); The resource processing rule is called management object rule (Managed Object Rules is called for short " MORules ").
Connect the argumentation of preamble about two big levels of software subsystem framework, continue here resource management layer wherein is divided into several subhierarchies, its hierarchical structure as shown in Figure 2.Be followed successively by from top to bottom:
The MORules layer is used to realize the processing rule of resource management object, mainly is meant the concrete rule of the method for operating relevant with resource etc., the required condition of deferring to etc. when calling DSP and handle resource and be required satisfied standard, service band resource;
The MORela layer, be used to realize the logical relation between the resource management object, satisfy certain logical relation between the various resources, function such as a certain resource realizes and must be possessed fully by the function of its beneath two child resources, like this this resource just satisfy with beneath two child resources and relation, similarly also have or relation, order relation, exponential relationship etc.Specifically:
Consider to exist two object A of direct set membership, B, guarantee the operate as normal of parent object A has following two kinds may require to its subobject B: essential, optionally.The present invention claim must the time this pass be " with relation ", the pass of optional time is " or relation ".
Have a class object, as the connecting object between the entity, because of this class object at aspects such as its state-detection, often be embodied in a certain entity, promptly embody certain " order relation ".
Exponential relationship is to concern from the influence that the quantity angle is further portrayed between the Object node in detail.Exponential relationship can be regarded as a kind of expansion of " or relation ", is the description of the Object node relation being carried out from quantity tolerance angle.
The MOInfo layer is used to realize the relevant information of resource management object itself, and some settings of various resources self, attribute etc. all belong to its relevant information, need use in resource management, operation such as carry out initialization, assignment, read;
The resource Drive Layer, being used to realize the driving interface of system hardware resources does not then need this one deck for logical resource.Basecoat is a system resource in addition, topmost then is to use processing layer.
The division of these levels makes OO management method become clear in the specific implementation of resource management layer, and the various attributes of resource management object need reasonably design when resource management layer realizes.The third embodiment of the present invention is on the basis of second embodiment, and its resource management layer is to realize the description of relevant information, logical relation, processing rule to the resource management object and preserve and safeguard by setting up object relationship tree.
Promptly corresponding each the resource management object of each node of object relationship tree, the attribute of node comprises the member property and the member function of resource management object, member property has been described the relevant information of resource management object, member function has been realized the processing rule of resource management object, the then corresponding logical relation of having described between the resource management object of the relation of node on the object relationship tree.The formation of this object relationship tree has been shown among Fig. 3.In fact this object relationship tree is exactly stratified object relationship figure, and the diagram that node is constituted is simplified here, and does not identify the title of each node, and these realize relevant with specific design.
The fourth embodiment of the present invention is on the basis of the 3rd embodiment, and further the method for setting up object relationship tree based on a kind of new introducing virtual objects node, shadow object node makes up the object relationship tree.This method is from object resource, this angle of condition managing, come clear description object and relation between objects for setting up the object relationship tree, and newly introduce virtual objects node, shadow object node, thereby can clearly describe the group relation of knowing between the object, realize that simultaneously angle solves fan-in/fan-out width problem; Thereby on realizing, program design sets up object relationship tree clearly.Specifically:
The object relationship tree is being increased newly in the entity object node process, when the fan-out of father's entity object node of this newly-increased entity node has reached predetermined limits, then create a shadow object node, remove the set membership of this father's entity object node and one sub-entity object node, with this fructification Object node and newly-increased node child node as shadow object; Again with the child node adding object relationship tree of shadow object node as above-mentioned father's entity object node; When carrying out system resource management, there is not child node if judge the shadow object node, then the shadow object node is carried out deletion action.Perhaps,
When setting up the object relationship tree, if a plurality of fructification objects of father's entity object belong to the different resource group, then create respectively and each resource group virtual objects node one to one, with the child node of virtual objects node as father's entity object node, to belong to the child node of the fructification Object node of same resource group, join in the object relationship tree as this resource group corresponding virtual Object node; When carrying out system resource management, set the set membership that goes up virtual objects node and entity object node according to object relationship, find the entity object node that belongs to same resource group, operate.Use the inventive method, can reduce the correlativity of handler code and concrete entity object, make things convenient for the maintenance and expansion of system
In addition in the fourth embodiment of the present invention, for the description of the relation between the Object node, then adopt a kind of new introducing and or relation, order relation, exponential relationship portray the method for object relationship in the logical relation between the portrayal node on the object relationship tree.This method is from the angle of resource management, propose and by and or relation, order relation, exponential relationship wait the complex relationship of portraying between the Object node; By portrayal to this three classes relation, attempt relation and the relation of influencing each other between the node in the complete portrayal object relationship tree, reach effective Organization And Management to the object resource information.
See the left side among Fig. 3 again, also be provided with a pointer to object table, in the table each pointer all point to for the resource management object, also be the node on the object relationship tree, can realize quick indexing by this method to the object relationship tree.Resource management layer set up the pointer to object table can the direct index object relationship node of tree, the pointer that comprises in this table all is the corresponding node of pointing on the object relationship tree, and system arranges pointer to object when setting up this table according to the type of system resource arrangement of its corresponding node.Such as of a sort pointer is arranged in together, can accelerate index speed like this, as shown in Figure 3: first arrow points upper layer node, second arrow points lower level node, and the chained list relation that same category node pointer is set up.These specific implementations can be selected according to real needs, do not influence the spirit and scope of the invention.In addition, can also in the list item of pointer to object table, preserve the processing rule of homogeneous object, to save the space, to accelerate access.
As seen, the purpose of introducing the pointer to object table has two: anchored object node at first fast, can arrive node corresponding according to the object type linear search, and need not to search from object tree; Secondly the processing rule of homogeneous object can be kept at the corresponding list item of this table, rather than is kept in such each Object node, can save the space so on the one hand, and it is unified to reach management on the other hand, and the change cost is also little.
From object relationship tree, be that MORules layer content mainly shows as two aspects to the processing rule of arbitrary management object node: influence to father node aspect " transmissions " from this node, be referred to as up; To child node aspect " transmission " influence, this paper is referred to as descending from this node.These two aspects respectively need corresponding processing rule.Therefore, be provided with for the resource management object: up processing rule is used to describe by this node on the object relationship tree and transmits the disposal route of influence to father node (comprising direct parent Object node and indirect parent Object node); The downlink processing rule is used to describe by this node on the object relationship tree and transmits the disposal route of influence to child node (comprising direct subclass Object node and indirect subclass Object node).
In addition,, generally a unified rule is arranged, be called general rule for whole object tree from versatility and specificity; And consider that some class object nodes understand some special processing needs, and need special-purpose processing rule, be called the special processing rule.Therefore the present invention also is provided with respectively separately to the up-downgoing processing rule: the common treatment rule is used to describe for object relationship sets the upward all general disposal route of all nodes, the unified rule of determining of given object tree; The special processing rule is used to describe the disposal route for this node special use on the described object relationship tree, and this is the processing rule that just is suitable for respect to concrete Object node, and this rule is not that whole object tree is suitable for.When specific implementation, realize the special processing rule with function, correspondence is provided with the call back function pointer of special processing rule, if need not special processing, then corresponding pointer is empty.
And according to the situation that whether adopts general rule, special rules, the combination of processing rule is meant the priority mode of rule treatments.Therefore have 4 kinds of combinations: only general rule, general rule behind special rules, the first special rules after special rules, the first general rule only.For what special rules paid particular attention to is that its processing can not destroy the restriction relation between the object tree node.The information of these processing rules is the content of MORules layer, also is kept in each Object node.
The front mentioned and upwards should provide unified from resource management layer and call, notified, mutual interface, between application processing layer and described resource management layer, call, notify, exist alternately as interface layer in the third embodiment of the invention by Service Access Point (Service Access Point is called for short " SAP ").This SAP interface layer includes: application programming interfaces (Application Programming Interface is called for short " API ") are used to realize from using the resource transfer interface that processing layer carries out to resource management layer as calling interface; Message (Message is called for short " MSG ") notification interface is used to realize using the message informing mechanism that processing layer carries out from the resource management course.Its structure is formed as shown in Figure 3, as seen from the figure, the SAP course is used processing layer transparent interface is provided, by api function call realization from the top down active inlet and realize that by the MSG notice notice from bottom to top causes, the SAP equivalent shield variation of lower floor's resource and relation to the influence of top higher layer applications.
What need here to mention especially is: the realization of MSG notification interface is different from traditional state variation case mechanism.Here have close association between each node owing to the object relationship tree, so the change events of any one node might cause the variation of a series of nodes related with it.A changes such as node, has caused the variation of nodes such as B, C, D simultaneously, and at this moment node A is the source that changes.In order to save resource, to simplify and handle, here the MSG notification interface only selects to notify the incident of the source node that causes current variation, such as the variation of only upwards notifying node A in the last example, and do not notify the variation of nodes such as B, C, D, the variation of these associations all is to be obtained again by the API Calls interface according to separately needs by corresponding upper layer module.
The Notification Method that simply can conclude the MSG notification interface is as follows:
When system resource changed, resource management layer detected the source object that causes variation, promptly causes the node of variation own, but not was subjected to other node to change the related node that just changes;
After this resource management layer is used processing layer by the MSG notification interface with the change events notice of source object, and each module on upper strata all will only be notified the upper layer module of registration to the registration of SAP interface during notice;
Use each module of processing layer then and just know the change events of other object that causes by source object, be i.e. the variation of other interdependent node that causes by the source node by the API Calls interface.
At last, ins and outs of need setting forth are exactly the structure of each object of specific implementation how, the fifth embodiment of the present invention is on the basis of the 3rd embodiment, handle for realizing the unified of general format, all Object nodes all have unified information field, and promptly all resource management objects have unified member's form.Can there be all system resources dissimilar, different attribute of a compatibility like this, and unified problem to identical form.The present invention is possible member by being provided with, and to not possessing the system resource of the described attribute of arbitrary member, is this member and is changed to invalid processing.Here claim that invalid member or field are meaningless field.Such as, it seems from using processing layer, concerning the A Object node, may its b information field be insignificant, and be insignificant B Object node a information field.
In addition, the meaningless field of object does not need for application layer to see that in order to handle this situation, the present invention has increased the one-level mapping relations at the SAP layer, to shield all meaningless fields to using processing layer, only provides the mapping of meaningful information field.This map information is kept at corresponding node, and finishing by the SAP layer of mapping relations realizes; Concerning each node, the value of its meaningless field can be defaulted as " effectively ".Whether so-called " effectively " for disposing, is exactly to dispose promptly; For whether on the throne, be exactly on the throne; For whether available, be exactly available, or the like.
At last, a problem that also needs to solve is: how to embody in entity and preserve similar management object node and attribute thereof.When reality realized, the present invention was provided with a configuration file and comes the description object relational tree, and other the function code that articulates is the embodiment that is provided with by the call entry then.Three layer MOInfo, MORela of resource management layer and the combination of MORules are realized by the data file mode.And the general rule of MORules is realized by code.The special rules of MORules realizes that by logon mode the device driver of physical resource also realizes by logon mode.So-called registration just is meant that processing rule or driver may be changed to sky when initialization, after correlative code is finished or after upgrading, needs the call entry of this code is filled into the relevant position.
Like this, when system resource changes, only need to upgrade the information of revising in corresponding configuration file or the data file, just can embody upgrading to change.And, then re-register the call entry to resource management layer for new processing rule function, driver.
Those of ordinary skill in the art are appreciated that, more than in the description for the embodiment of the invention, institute is illustrational about parameter setting, implementation etc., all can realize by the replacement scheme of same principle, be that example is discussed and do not limited range of application of the present invention with the mobile communication base station equipment system equally, as long as in same architecture, the electronic information that also has system resource, processor, software subsystem, higher layer applications service, all the present invention can be used wherein, can realize goal of the invention, and not influence the spirit and scope of the invention.
Though by with reference to some preferred embodiment of the present invention, the present invention is illustrated and describes, those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
