Mobile station apparatus 3 is the terminal installation that uses in the mobile body communication systems such as existing known mobile telephone terminal or phs terminal, by and base station apparatus 2 between receive and dispatch electric wave, come to communicate with base station apparatus 2.And mobile station apparatus 3 at this moment uses time slot as specific call distribution unit as described later, carries out time-division multiplex communication.Moreover, in the present embodiment,, be called call distribution unit with using a plurality of communication resources to carry out the communication resource under the situation of 1 communication.In addition in the present embodiment, though be that example is described with regard to time division multiplexing mode, the present invention also is applicable to, for example in frequency division multiplexing mode or the code division multiplexing mode, the situation of using the communication resource in the multiplex mode separately to communicate.
Here, to constituting the technology of background of the present invention, be elaborated.
At first, with reference to Fig. 8, with regard to the use situation of the time slot under the situation about communicating between mobile station apparatus 3 and the base station apparatus 2, diagrammatic illustration.Among this figure, be that example describes with 2 mobile station apparatus 3.In addition, mobile station apparatus 3-1 and mobile station apparatus 3-2 are the time slot that appointment should be assigned with and communicate.In addition, establish transmission and undertaken by mobile station apparatus, the kind of calling is a packet call.
Moreover, as the example of the situation of specifying the time slot that should be assigned with, can enumerate multilink and connect (multilink).So-called multilink connects, and is by using a plurality of time slots, can be with this connected mode of using the total speed of the speed of time slot to communicate.For example, under the situation of PHS system, provided by the common carrier service: by shared a plurality of time slots (32kbps) in packet switching, the multilink that communicates with the speed (being generally 64kbps, 128kbps) of the multiple of 32kbps connects.In circuit switched, also provided by the common carrier service equally: by occupying a plurality of time slots (32kbps), the multilink that communicates with the speed (being generally 64kbps) of the multiple of 32kbps connects.Like this, though under the situation that multilink connects, can use a plurality of time slots simultaneously,, specify in advance and use a plurality of time slots in order to set virtual link.Therefore, multilink connects calling and must distribute appointed time slot.Relative therewith, under the situation that non-multilink connects, because the time slot of 1 sub-distribution is 1, therefore no matter be which time slot can use.The details that multilink connects is seen the RFC1990 in the technological normative document of the Internet for example.
At first, mobile station apparatus 3-2 when beginning to communicate with base station apparatus 2, specifies time slot 1 back request to distribute this time slot 1 (S100).Then, if this time slot 1 is not used, base station apparatus 2 is handled, and this time slot 1 is distributed to packet call (S102) with mobile station apparatus 3-2.Then, mobile station apparatus 3-1, when beginning and base station apparatus 2 communicated, appointment time slot 1 or 2 back requests distributed any one (S104) in this time slot.Promptly, after mobile station apparatus 3-1 specifies 2 time slots, the multilink implementing to communicate by letter connects and calls out communication down, here, though appointment time slot 1 or 2, but a unit as if in the call distribution processing of seeing packet call emphatically then can use any one in time slot 1 or 2.Here, be under the situation about can not use with the call distribution of other mobile station apparatus 3 at for example time slot 2, base station apparatus 2 makes the processing (S106) that distributes standby.Time slot 1 on the other hand, by from distributing under the situation of mobile station apparatus 3-2 through certain hour or the grouping that will not communicate by letter temporary transient discharge (S108).Like this,, therefore handle, will distribute to this time slot 1 (S110) with the packet call of mobile station apparatus 3-1 because time slot 1 is in the state that is not used.By handling repeatedly, can specify time slot and make many mobile station apparatus 3 and base station apparatus 2 carry out packet communication.Have, though not shown, mobile station apparatus 3-1 can ask 2 S104 simultaneously again.Like this, can in connecting, multilink use a plurality of time slots to communicate simultaneously.
Below, specify above-mentioned call distribution and handle.The control part 20 of base station apparatus 2 and storage part 22, on the function as shown in Figure 9, comprise: queue management portion 150, waiting list 151, qualification formation 155 and time slot management department 158 constitute, and wireless communication part 21 comprises: communication control unit 60 and Department of Communication Force 61 constitute.
Limit formation 155, as shown in figure 10,, be contained in the storage part 22 for each time slot being provided with the memory module of the first in first out of time slot counterpart.This limits formation 155, can store a plurality of call data to determined number at each time slot counterpart.Among this figure, time slot is 4.In addition, " call data " this speech here uses as the speech that comprises packet call data and these both sides of circuit switched call data.The circuit switched call data can be the ID that for example represents that this circuit switched is called out in addition.Here so-called ID can be in base station apparatus 2, and each is called out the ID of unique management.Equally, the packet call data also can be the above-mentioned ID that for example represents this packet call.
In addition, the memory module of the first in first out that waiting list 151 is comprised for storage part 22 can be stored a plurality of packet call data.
When producing new circuit switched,, then distribute this time slot if the time slot that should distribute is not used.Under the situation that the time slot that should distribute is used, judge in the time slot counterpart corresponding with the above-mentioned time slot that should distribute that limits formation 155, whether can the stored calls data.Then, in the time of can the stored calls data in this time slot counterpart, represent the circuit switched call data that this circuit switched is called out, be stored in this time slot counterpart.On the other hand, when can not the stored calls data in this time slot counterpart, do not implement to be stored in waiting list 151 backs and wait for this action, the transmit leg of request for allocation is sent distribute refusal.Why like this, be must connect immediately because circuit switched is called out.Here the so-called time slot that should distribute limits under the situation of calling out at time slot, is appointed time slot; Under the situation of the non-limiting calling of time slot, be assignable whole time slot.
On the other hand, if the time slot that should distribute is not used, new packet call then is assigned to this time slot.If the time slot that should distribute is used, whether then queue management portion 150 is judged in the time slot counterpart corresponding with the above-mentioned time slot that should distribute that limits formation 155, can the stored calls data.Then, can the stored calls data conditions in this time slot counterpart under, represent the packet call data of this packet call to be stored in this time slot counterpart.On the other hand, can not the stored calls data conditions in this time slot counterpart under, these packet call data are stored in the waiting list 151.
Then, for stored packet call data in waiting list 151, whether queue management portion 150 in the time slot counterpart corresponding with the above-mentioned time slot that should distribute that limits formation 155, can the stored calls data monitor.Then, be judged as in queue management portion 150, can the stored calls data conditions in this time slot counterpart under, in this time slot counterpart, be stored in stored packet call data in the waiting list 151.
For stored calls data in limiting formation 155, whether 150 pairs in queue management portion uses the time slot that should distribute to monitor.Then, be judged as under the untapped state of this time slot, promptly be judged as under the state that calling is not assigned with in queue management portion 150, with this time slot distribute in this qualification formation 155 in the stored calls data, stored calls data at first.
Here, for stored calls data in limiting formation 155, with entering definite time slot that uses of the moment that limits formation 155.That is, limit formation 155, each time slot is provided with the time slot counterpart, the time slot corresponding with this time slot counterpart only distributed in the calling of stored calls data representation in certain time slot counterpart.
The processing of distribute calling out to time slot, specifically, by management in time slot management department 158, be stored in the processing in the corresponding part of this time slot with time slot user mode table shown in Figure 6.Then, give the call distribution time slot if so, then begin call treatment, communicate with Department of Communication Force 61 at this time slot.
Like this, just can untapped time slot be distributed successively and call out.Yet, under the situation of the non-limiting calling of time slot,, limit formation 155 in case distribute to even if any time slot can both use, though other time slot be in the free time also must standby in limiting formation 155, therefore the problem that produces is exactly that the utilization ratio of time slot is low.
In the present embodiment, solve this problem, and can in the time slot of calling out distributes, improve the utilization ratio of time slot.Below, should handle being elaborated.
Fig. 3 is the functional block diagram of the base station apparatus 2 in the present embodiment.The control part 20 of base station apparatus 2 and storage part 22, as shown in the drawing on the function, comprise: queue management portion 50, waiting list 51, formation division 53, formation 54 usually, qualification formation 55, circuit formation 56, time slot dispenser 57, time slot management department 58 and holding calling storage part 59 constitute.Wireless communication part 21, it comprises: communication control unit 60 and Department of Communication Force 61 constitute.In addition, formation 54 usually, qualification formation 55, circuit formation 56 constitute formation divisions 53.
Waiting list 51 for the memory module of the first in first out that comprises in the storage part 22, can be stored a plurality of packet call data.And this waits for formation 51, stores a plurality of ID as the packet call data as shown in Figure 4.And, waiting list 51, corresponding with each ID, to be the appointed time slot of time slot limit call out, or the classification of the non-limiting calling of the unappropriated time slot of time slot store, and limit under the situation of calling out at time slot, time slot to be named corresponding with ID again storage.And, not having under the situation to determined number of surpassing in the quantity of stored packet call data, waiting list 51 can the stores packets call data, if the quantity of stored packet call data then can not be stored above to determined number.
Usually formation 54 is the memory module of the first in first out that comprises in the storage part 22, and it is stored the packet call data as the packet call of the non-limiting calling of time slot.In addition, limiting formation 55 also is contained in the storage part 22.Limiting formation 55, as shown in Figure 5, is the memory module that each time slot is provided with the first in first out of time slot counterpart, and the packet call data as the packet call of the non-limiting calling of time slot are stored.In addition, establishing time slot among this figure is 4.Circuit formation 56 also is the memory module of the first in first out that comprised of storage part 22, and the circuit switched call data are stored.This each formation, also with wait same to formation 51, when the quantity of stored calls data does not surpass to determined number, can the stored calls data; When the quantity of stored calls data surpasses to determined number, then can not store.
When producing the new line switched call, if the time slot that should distribute is not used, then this new line switched call is assigned to this time slot.On the other hand, under the situation that the time slot that should distribute is used, can 50 pairs in queue management portion store the circuit call data and judge in circuit formation 56.Then, can in this time slot counterpart, store under the situation of circuit call data, represent that the circuit switched call data that this circuit switched is called out are stored in this circuit formation 56.On the other hand, in this circuit formation 56, can not store under the circuit switched call data conditions, not implement it is stored in the action of waiting in the waiting list 51, to the transmit leg transmission distribution refusal of request for allocation.Why like this, be must connect immediately because circuit switched is called out.
Moreover, the connection requests immediately that circuit switched is called out, strong than packet call.Therefore, under having the situation can move to packet call in the waiting list 51, in the communication, promptly have under the situation of the packet call of having distributed to time slot and having established communication, queue management portion 50 can move to this packet call in the waiting list 51.That is, be stored in the waiting list 51 after the time slot de-allocation of queue management portion 50 with this packet call, and this time slot distributed to above-mentioned circuit switched call out.
On the other hand, if the time slot that should distribute is not used, new packet call then is assigned to this time slot.Under the situation that the time slot that should distribute is used, if being time slot, this packet call limits calling, queue management portion 50, to the corresponding part of the corresponding time slot of the above-mentioned time slot that should distribute that limits formation 55 in, whether can judge by the stores packets call data.Then, can the situation of stores packets call data in this time slot counterpart under, represent that the packet call data of this packet call are stored in this time slot counterpart.On the other hand, can not the situation of stores packets call data in this time slot counterpart under, these packet call data are stored in the waiting list 51.
In addition, be the non-limiting calling of time slot at this packet call, under the time slot that should the distribute situation about not being used, can 50 pairs in queue management portion be being judged by the stores packets call data in the formation 54 usually.Then, can the situation of stores packets call data in this common formation 54 under, represent that the packet call data of this packet call are stored in this common formation 54.On the other hand, can not the situation of stores packets call data in this common formation 54 under, these packet call data are stored in the waiting list 51.
Moreover, use in the circuit switched call under the situation of all time slots that can distribute certain packet call, promptly the stored calls data all are under the situation of circuit switched call data in time slot storage list described later, can no matter whether store the packet call data in formation 54 or the qualification formation 55 usually, all the transmit leg to request for allocation sends the distribution refusal.This be because, all called out under the situation about taking at all time slots that can distribute this packet call by circuit switched, unpredictable this circuit switched is called out and when is cut off, and till being cut off during this section, packet call is in the state that can't communicate by letter.
Then, for stored packet call data in waiting list 51, if the time slot that is categorized as of stored packet call data limits calling at first, then can queue management portion monitor by the stores packets call data 50 pairs of above-mentioned should distribution in the corresponding time slot counterpart of time slot with qualification formation 55.Then, if can the stores packets call data in this time slot counterpart, queue assignment portion 52 be stored in stored packet call data in the waiting list 51 in this time slot counterpart.On the other hand, if at first the stored packet call data be categorized as the non-limiting calling of time slot, then can 50 pairs in queue management portion monitoring by the stores packets call data in the formation 54 usually.Then, if can the stores packets call data in this time slot counterpart, then queue assignment portion 52 be stored in stored packet call data in the waiting list 51 in this common formation 54.
For stored packet call data in limiting formation 55, queue management portion 50 monitors whether the time slot that should distribute is used.Then, if be in state that this time slot is not used, promptly call out the state that is not assigned with, queue management portion 50, give be stored in the corresponding time slot counterpart of the time slot that should distribute of this qualification formation 55 in the packet call data in, stored packet call data at first, distribute this time slot.
In addition here, for example judge in queue management portion 50 do not have the stores packets call data in the common formation 54, etc. to formation 51 in the packet call classification of Data of oldest stored be that time slot limits under the situation of calling out, queue assignment portion 52, can by in the stored packet call data in waiting list 51, with just now the storage order confirm this packet call classification of Data, read in the non-limiting calling of time slot, the packet call data of oldest stored, be written in the common formation 54.In addition, judge in queue management portion 50 do not have in certain the time slot counterpart that is limiting formation 55 stores packets call data, the oldest stored packet call classification of Data in waiting list 51 be under the situation of the non-limiting calling of time slot too, queue assignment portion 52, can be by with the order of storage earlier, confirm the classification and the appointed time slot of stored packet call data successively, read out in the appointed time slot of this time slot limit call out in, the packet call data of oldest stored, be written to and limit formation 55.
Like this, to stored calls data in common formation 54, qualification formation 55 or the circuit formation 56, implement the time slot allocation process.Specifically as mentioned above, be with Fig. 6 in the processing of storing in the corresponding part of this time slot of illustrative time slot user mode table.This time slot storage list, as shown in the drawing, for to each time slot, store the table of call data in the use of this time slot.Then, when groove was in the state that is not used at a time, time slot management department 58 was with the call data deletion of time slot corresponding in this time slot user mode table.Queue management portion 50 then, judge certain time slot be in the state that is not used, when promptly detecting the state that does not have the stored calls data in this time slot that is in time slot user mode table when not being used (detect call distribution unit), time slot dispenser 57, with given priority, give this time slot with stored calls data allocations in common formation 54, qualification formation 55 or the circuit formation 56.Time slot management department 58 by these call data being stored in the time slot user mode table, implements and the allocation process of calling out corresponding time slot then.Like this, to behind the call distribution time slot, communication control unit 60 begins the call treatment of this calling, and communicates with Department of Communication Force 61.
Moreover the packet call that is assigned with time slot is when satisfying specified criteria, and distribution is disengaged, and is stored in the waiting list 51.Specifically, for example can by instrumentation from time slot management department 58, be assigned to time of time slot, this time is managed, from being assigned with, distributing through removing under the situation of preset time.In addition, also can to from time slot management department 58, the number of packet that is assigned to time slot manages, when surpassing given number of packet, remove and distribute.In addition, also can when the grouping that will not continue to communicate by letter, remove and distribute.Perhaps, can the time slot de-allocation of the longest packet call of time will be communicated storing under the packet call data conditions in the formation 54 usually.Moreover in this case, when the grouping that will not continue to communicate by letter, before the packet call storage that will represent to remove the packet call that this time slot distributes is in waiting list 51, to produce answer communication packet during, be stored in the holding calling storage part 59.
By more than, can in the time slot of calling out distributes, improve the utilization ratio of time slot.
Moreover, can make the time slot counterpart or the circuit formation 56 of above-mentioned common formation 54, qualification formation 55, only store 1 call data respectively.Like this, can cut down storage area, and limit calling, can prevent that time slot from limiting calling and just being stored in qualification formation 55 for the time slot of a plurality of time slots of appointment, though other appointment time slot free time, the situation that also can't distribute time slot.
With reference to the process chart in the base station apparatus 2, more specific description is carried out in above processing.
Fig. 7 is the process chart in queue management portion 50, time slot dispenser 57 and the time slot management department 58.
At first base station apparatus 2, to the time slot that whether has calling not to be assigned with, be whether to store call data in the time slot storage list to monitor (S200).When the time slot that has calling not to be assigned with, base station apparatus 2 in the stored calls data, is at first declared (S202) to whether storing circuit switched call data in the circuit formation 56 in formation 54 usually, qualification formation 55 or circuit formation 56.Then, when storing the circuit switched call data, base station apparatus 2 is stored this circuit switched call data by the stored calls section data that do not have at the time slot storage list, come circuit switched call data, distribute time slot (S204) representing that this circuit switched is called out.
On the other hand, do not storing under the circuit switched call data conditions, base station apparatus 2, next to limit formation 55, whether store the packet call data in the corresponding time slot counterpart of time slot that is not assigned with and judge (S206) with calling out.Then, when storing the packet call data in this time slot counterpart, base station apparatus 2 by these packet call data of storage in the time slot storage list, comes the packet call to this packet call data representation, distributes time slot (S208).
When not having the stores packets call data in this time slot counterpart, base station apparatus 2 is judged (S210) to whether store the packet call data in common formation 54 again.Then, under situation about storing, base station apparatus 2 by these packet call data of storage in the time slot storage list, comes the packet call to this packet call data representation, distributes time slot (S212).
Then, distributing by above processing under the situation of time slot, base station apparatus 2 is by repeating that (S200) handled in the supervision that whether has the time slot that calling is not assigned with, under the situation that has idle time slot, repeat to distribute the processing of calling out to this time slot.In addition, be not stored at the call data that should distribute under the situation of any one formation, base station apparatus 2 is waited for the generation of next call.
Moreover, the processing from above-mentioned S202 to S212, base station apparatus 2 is though confirm that with the order of circuit formation 56, qualification formation 55, formation 54 usually call data are stored, but also can enoughly have the processing of given preferred sequence, replace the order of confirming them.What is called has the processing of priority, be meant the processing of for example changing the kind of the calling of distributing to time slot according to the distribution number of times in past, confirm with the order of circuit formation 56, qualification formation 55, formation 54 usually at first, and given the circuit switched call distribution under the situation of time slot at continuous 2 times, just to limit formation 55, formation 54 usually, circuit formation 56 switching affirmation order like this.
By a series of processing of above explanation, can avoid the non-limiting calling of time slot just to be stored in and limit formation 155, even other time slot free time, also can't distribute the phenomenon of time slot.Like this, can in distributing, the time slot of calling out improve the utilization ratio of time slot.
For example, except mobile body communication system,, can both be suitable for so long as use a plurality of call distribution units to carry out the communicator of packet communication.Specifically, for example also be applicable to and carry out in the time-multiplexed wire communication.
