Description
The present invention relates to the call standby method in the relay wireless system (TRS).Or rather, relate to distributed data and handle call standby method in the relay wireless system.
Relay wireless system (TRS) is construed to a kind of communication equipment usually, is used to because the signal jam that the shared single frequency band of a plurality of electric terminals may often appear in the telephone communication provides a kind of solution, and above-mentioned terminal is known as the TRS terminal.
The call standby function be when all RF channels when busy, another call information of a terminal request is stored, and when channel becomes the free time, finishes connection in proper order according to the request of terminal.
On August 13rd, 1991, laid-open U.S. Patents disclosed a kind of method of calling and device that is used for the relay wireless communications system for No. 5040237.With reference to Fig. 1 and 2, below a common relay wireless system is described.
Common relay wireless system (TRS) can make Anywhere calling a plurality of Portable Communications Units or certain Portable Communications Unit of a terminal use in telecommunications network.This TRS comprises personal wireless terminal 3, such as moving or portable radio device and each and repeater 2 of terminal 3 are connected to each other by the information that wireless transmission and relaying are propagated the identifier of terminal 3 spendable channel informations, terminal 3 and position of all conventional TRS customer service is provided.This TRS also comprises a network switch 1, and its unified each repeater 2 of control is to be connected them with a network and external call circuit.
Following description be the course of work about general T RS.
2 pairs of call connection request from each terminal 3 of repeater are in standby condition (S31), and determine whether (S32) has the call connection request from arbitrary terminal 3.If there is not call connection request, repeater 2 turns back to step 31, if there is a call connection request, repeater 2 is determined the number of (S33) alternate channel.If this alternate channel is not a unique channel, repeater 2 is carried out (S331) call treatment and is determined whether (S35) exists the channel of a terminated call.Otherwise if there is a single alternate channel, repeater 2 is carried out (S34) according to priority and is called out connection, and determines whether the channel of a terminated call.
If there is not the channel of terminated call, repeater 2 execution in step S35 are to determine whether to exist the channel of terminated call, till they find an idle channel.Yet if having the channel of terminated call, repeater 2 is carried out to call out and is finished processing to turn back to stand-by state (S31).
The call connection request of terminal 3 is handled according to the message from repeater 2 and is begun to prepare (S41).Terminal 3 determines whether all channels send in the space from repeater 2 in the message of using (S42).Call connection request in the terminal 3 means that a terminal use attempts a calling and connects, promptly pushes a transmit button.
If terminal 3 is received any message that all channels are used, terminal 3 is prepared the message of (S41) reception from repeater 2.On the contrary, if terminal 3 does not receive the message that all channels are used, they determine the existence of (S43) call connection request.If there is not call connection request, terminal 3 determines whether they receive the message that all channels are used (S42).Yet if there is this call connection request, terminal 3 request (S44) repeaters 2 are handled these callings, and determine (S45) whether repeater 2 is made with this call request to be connected.If terminal 3 is carried out (S46) call request connection, and determine whether (S47) should calling connect end.
Connect not end if call out, whether this terminal definite (S46) calls out to connect is finished, till this calls out the connection end.Yet, finishing if should call out to connect, this terminal execution (S48) is called out and is finished processing, turns back to stand-by state (S41) then.
Simultaneously, do not make call request and connect if this terminal is found repeater 2, this terminal shows that (S451) calls out the connection fault, and turns back to stand-by state (S41).
Subscribed and used each wireless terminal of the general T RS of distributed data treatment technology that this system is had different rights, and each user is talked by phone as shown in Figure 2.
With reference now to Fig. 2,, following description is promptly used under the situation of each channel initial condition nobody relevant for this situation, and repeater 2 has five RF channels, and wireless terminal is group A, B and C.
If receiving and send this backward signalling, another terminal of arbitrary terminal call group B of group B, repeater 2 can receive all terminals transmissions of the mode of backward signalling with each terminal to the B group.At this moment, the channel that just using of this repeater is by the agreement channel appointed.
Though group B is for busy, because 4 RF channel idle so they can reply next backward signalling from arbitrary terminal, can be handled 5 backward signallings at time repeater thus.If 4 channels are busy, a channel idle, then this repeater can be controlled each terminal according to the priority of each terminal.
Yet, in this general T RS, a wireless channel that is just using controls that each terminal will be used or obsolete all the other channels, and when all RF channels when busy, another the terminal of not using not connect by call try, till more than one wireless channel becomes the free time.
An object of the present invention is provides a kind of call standby method in distributed data processing relay wireless system, the use call standby operation execution in the relay wireless system that uses distributed data to handle of this method is called out and connected, and calls out joint efficiency with raising.

There is the identical structure with the RS of general T shown in Fig. 1 in relay wireless system of the present invention (TRS).The call standby operation that can not realize basically in general T RS is used in the present invention now, forms call standby method of the present invention.According to this method, when all channels are all occupied,, tell that all occupied message of whole channels is sent continuously with all terminals of this message informing, the operation subsequently of each terminal is as follows:
In being in each terminal of stand-by state, receiving all channels and measure and preserve in each terminal of the message of using and receive this message from it and make the time of call request to it.From the issue of this message the time by measured time delay after, each terminal can send a call connection request.Each terminal sends call connection request in a predetermined time period, this predetermined time period is by increasing on time of delay or reducing by a time durations by the priority decision of each channel from time of delay and set.
Like this, the priority of terminal is low more, and it is just many more to be increased to the measured temporal time.In being in each terminal of call standby state, even after the issue of described message, also there is not the terminal of connection to have a time of delay that is deducted the message sink number of times.Each deducts rate and is divided by the priority of each terminal.At this moment, this issue terminal situation that receives this message is counted as once.
For example, priority number 1 can be determined by the time of message sink decision each time, and priority number 2 was determined by the time of per twice message sink decision.If terminal does not receive the message about call connection request from repeater, this terminal can send a call connection request again in a time durations, described time durations is to be added to go up during predetermined time of delay by the time that will measure in the above described manner to set.
Subsequently, when an end in use the time, be busy message if this terminal receives all channels from repeater, then this terminal has during predetermined retention time, to have the high priority of terminal that is in stand-by state than other.Each channel was busy message during repeater sent a retention time, if in the retention time of appointment, be not in the call connection request of busy terminal or one group of terminal from the past, repeater stops to send each channel and is busy message, connects the call connection request of replying the terminal that is in stand-by state according to the priority of each terminal for calling out then.
Following description relates to the process at repeater and call between terminals standby operation.
With reference to figure 5, the working procedure of repeater that relates to the call connection request of each terminal is described as follows.
Repeater is prepared (S51) and whether is had any call connection request from each terminal 3 receipt of call connection request and definite (S52).When not from the call connection request of arbitrary terminal, repeater turns back to the stand-by state of (S51) call connection request, and when having a call connection request, whether alternate channel is one to repeater definite (S53).When this alternate channel was not one, repeater was carried out (S531) calling and is connected, and continued to determine whether (S532) exists one to call out the channel that connection has finished.If for not, repeater continues to determine whether (S532) exists therein a calling to connect the channel that has finished.On the contrary, if calling connection end, repeater is carried out (S58) calling and is finished processing, and turns back to the stand-by state of (S51) preparation reception from the calling connection of each terminal 3.
In contrast, if alternate channel is one, repeater is carried out (S54) and is called out and connect beaming back the message that (S55) all channels all are in use, and determines whether (S56) exists therein a calling to connect the channel that has finished.When not having such channel, repeater sends all in use message of (S55) all channels.Yet when existence one calling therein connected the channel that has finished, repeater stopped (S57) and sends this message, and determined whether (S532) should call out connection and finish.
Described below is attended operation about terminal.
At first, with reference to figure 6, the calling of describing each terminal according to a first advantageous embodiment of the invention connects.
Terminal is prepared (S61) and is received message from repeater 2, and whether they receive all channels from repeater 2 and all be in message the use to determine (S62).When they did not receive this message, each terminal determined whether (S63) exists a call connection request.
When not having call connection request, when terminal receives all channels when all being in message in the use, terminal turns back to (S61) stand-by state.Terminal determines whether (S62) receives all channels from repeater and be busy message.On the contrary, when existence one call connection request, terminal request (S64) repeater is carried out to call out and is connected, and determines whether they are connected with the repeater connection (S65).
When terminal and repeater are connected when being connected, their are carried out (S66) and call out and connect, and determine whether (S67) calls out and connect end.
If should call out not end of connection, each terminal continues to determine whether (S66) this calling connection finishes to connect end up to this calling.Yet when this called out the connection end, terminal was carried out (S68) calling and is finished processing, turns back to stand-by state (S61) then.
When terminal was not connected with the repeater connection, their showed that (S651) calls out connection failure, and turn back to stand-by state (S61).
When terminal found all channels all to be in message in the use by the existence of determining message, terminal was measured (S621) and is received this message from them and make the time of call connection request to them, and determines whether (S622) exists a call connection request.
In case there is call connection request, this terminal is ended the measurement of above-mentioned time, and storage (S623) this time, to determine (S624) whether all channels are busy message abort.
When this message abort, terminal is ended (S625) at the time durations of measuring in the above described manner, and proceeds to the state (S64) that request repeater execution calling connects.
With reference now to Fig. 7 A and 7B,, be described according to the calling connection of second preferred embodiment of the present invention to each terminal.
Each terminal is prepared (S71) and is received message from repeater 2, and they receive all channels from repeater 2 and all are in message the use to determine (S72).When they do not receive this message; Determine whether (S73) has call connection request.When not having call connection request, each terminal proceeds to stand-by state (S71).On the contrary, when existence one call connection request, each terminal request (S74) repeater is carried out to call out and is connected, and determines whether they are connected with the repeater connection (S75).
When terminal and repeater are connected when being connected, their are carried out (S76) and call out and connect, and determine whether (S77) calls out and connect end.
Do not have to finish if call out to connect, each terminal continuation determines that (S76) calls out connection and whether finish to connect end until this calling.Yet when this called out the connection end, each terminal was carried out (S78) calling and is finished processing, turns back to stand-by state (S71) then.
Fail to connect when being connected with repeater when terminal, their show (S751) this calling connection failure, and turn back to stand-by state (S71).When terminal when determining that message exists (S72) to find all channels all to be in message in the use, each terminal measurement (S721) receives this message from them and makes the time of call connection request to them, and determines whether (S722) exists a call connection request.
In case there is call connection request, each terminal is ended the measurement of above-mentioned time, and storage (S723) this time, to determine (S724) whether all channels are busy message abort.
When this message abort, each terminal is ended (S725) at the time durations of measuring in the above described manner, and proceeds to the state (S726) that deducts time of delay according to each terminal priority.Then, each terminal request (S727) repeater is carried out to call out and is connected, and whether they are connected with the repeater connection with definite (S728).
Be connected if each terminal is connected with repeater, they are carried out (S76) and call out connection.On the contrary, fail to connect when being connected with repeater when them, they carry out the increase state (S729) of time of delay according to each terminal priority.Carry out the state (S727) that connects of calling out by proceeding to the request repeater, terminal call try once more connects.
Irrealizable call standby method of the present invention can bring convenience for the user in general T RS, thereby has improved channel transport efficiency and the performance of (pre-existing) system is arranged earlier, and has reduced the required expense of channel expansion investment.
Though be considered to the most practical preferred embodiment invention has been described in conjunction with current, very clear, the present invention is not limited in the disclosed embodiments, it is with topped various improvement and the equivalents that is included in appended design and the scope.
