Figure 10 is for for illustrating the figure about an example in merging cycle of equipment according to a preferred embodiment of the invention.
Suppose that equipment D1 has 2 resource R1, R2, and NA1 is carried out and is made the resource B of NA1 and resource R1 and the R2 that C is connected to equipment D1, NA2 is carried out and is made the resource A of NA2 and resource R1 and the R2 that C is connected to equipment D1, requires transaction management unit 151 can calculate as illustrated in fig. 10 and maintain the information about the merging read-write cycle for equipment D1 (MRP, MWP).
And, require transaction management unit 151 in the situation that the new merging read-write cycle of calculating different from the existing merging read-write cycle, to transaction management unit 153 and affairs selected cell 155 request jobs.That is, require transaction management unit 151 increasing, change, deletion etc. be while requiring the change of item, to transaction management unit 153 and affairs selected cell 155 request jobs.For example, require transaction management unit 151 item that requires of the periodicity read-write about from network application (NA) sensing equipment can be offered to transaction management unit 153 or affairs rotary unit 155 and request job.
The affairs that transaction management unit 153 is grasped and management equipment is supported.That is, transaction management unit 153 grasp and update the equipment supported form of message or communication mode.
In other words, when being registered in the equipment changing (new registration, change, deletion etc.) of network service function layer (NSCL) or existing while requiring the job request of transaction management unit 151, the type of the affairs that may occur between network service function layer (NSCL) and equipment is grasped and upgraded in transaction management unit 153.
At this, affairs refer to that sender sends message one time to recipient, or sender sends a message and receives corresponding with it response message to recipient.In addition, the registration of equipment or change not only comprise that equipment is connected in network service function layer (NSCL) with physics mode, but also comprise device identifying information change.For example, when equipment manufacturers' release can be connected in the new product of network service function layer (NSCL) or the specification of change existing product, device identifying information is subject to variation.
Now, can using from equipment, read or write device in resource be actually what and in the middle of equipment and network service function layer (NSCL) actually first from which side transmit message as benchmark and between to equipment and network service function layer (NSCL) affairs of generation classify.For example, if the resource reading from equipment is A, to want the resource of write device be B, and the affairs that first transmit message from equipment side consist of two following steps.
Step 1): equipment carrying A value also sends the message of asking to be set in the value of B to network service function layer (NSCL).
Step 2): receive the network service function layer (NSCL) of the message being transmitted by equipment to carry the message response equipment of the value that need to be set in B.
That is,, if know what the resource that equipment has is, resource that can be by will read in any set device, want the resource of write device and what first transmit is the affairs which side grasps possible all forms.The affairs that equipment is supported can be the parts in the affairs of all forms of grasping.
To sum up, transaction management unit 153 calculates the equipment only consisting of the affairs that in the middle of the affairs of all forms, equipment is supported and supports transaction information (transaction-supported-by-device:TSD).Now, take care of and the equipment that maintains supports the mode of transaction information (TSD) to be accomplished in several ways.For example, the all elements of can memory device supporting transaction information (TSD), or only memory device is supported several rules that transaction information (TSD) has, or in the middle of only storing all possible affairs, the equipment that is not contained in is supported the affairs in transaction information (TSD).
The figure that Figure 11 and Figure 12 operate for the transaction management for illustrating according to a preferred embodiment of the invention.
As shown in figure 11, transaction management unit 153 can obtain the affairs of possible all forms.Wherein, " transaction element(affairs element) " " push attribute(pushes attribute) " represent whether be that equipment pushes (device push).The resource that " read element(reads element) " indicates to read from equipment.The resource of " write element(writes the element) " write device of indicating.
For example, final affairs are that network service function layer (NSCL) reads R1 and R2 value from equipment, carry out the work to devices allocation R1 and R2 value simultaneously, and the side that expression transmits message is for the first time equipment.
Illustrate in greater detail the operation of these affairs, if the R1 of equipment D1 and R2 value are respectively 5 and 7 at present, equipment D1 sends to network service function layer (NSCL) by the message as shown in Figure 12 (a).At this, " request element(request element) " indicate to receive the resource of coming from network service function layer (NSCL)." read element(reads element) " represents the value of the resource that network service function layer (NSCL) will read from equipment D1.Then, if receive the network service function layer (NSCL) of this message, the R1 of equipment D1 and R2 value to be set as respectively to 10 and 11, can use the message response as shown in Figure 12 (b).Wherein, " write element(writes element) " represents that network service function layer (NSCL) wants the value of the resource of write device D1.
Figure 13 is for the figure of an example of equipment support transaction information is according to a preferred embodiment of the invention described.
Transaction management unit 153 utilizes the tables of data (datasheet) of equipment D1 etc. and the type of the affairs that the equipment of grasp D1 supports, thereby can extract as illustrated in fig. 13 and maintain the equipment support transaction information (TSD) only consisting of the affairs that in the middle of the affairs of possible all forms, equipment D1 supports.
And if the type change of affairs, transaction management unit 153 is to affairs selected cell 155 request jobs.That is, transaction management unit 153 will change factual report to affairs selected cell 155 when equipment is supported transaction information (TSD) change.For example, transaction management unit 153 can support transaction information (TSD) to offer affairs selected cell 155 and the report change fact equipment of change.
Affairs selected cell 155 is determined type and the frequency of the affairs between network service function layer (NSCL) and equipment.That is, affairs selected cell 155 is using the feature of the communication request frequency of each resource and per unit communication mode as primary variables, and utilizes greedy algorithm (Greedy algorithm) and determine type and the frequency of affairs.
In other words, when existing when requiring the job request of transaction management unit 151 or transaction management unit 153, affairs selected cell 155 is wanted respectively the actual affairs of carrying out in the middle of selection equipment support transaction information (TSD) for each relevant device, and the execution cycle of definite each affairs of selecting.Be this problem to be considered as to weight-sets cover (weighted set cover) problem in the present invention, and utilize greedy algorithm to go to solve.At this, it is primary variables that will merge read cycle (MRP), merge write cycle (MWP), equipment is supported transaction information (TSD) etc. used.
