Description
Invention field
The present invention relates to cellular voice and Cellular Digital Packet Data (CDPD) telecommunication system and operation method thereof.
Background of invention
In traditional cellular radio network, for providing a base station by each the honeycomb district in the zone of Cellular Networks service.Each base station comprises a plurality of radio receiving-transmitting units, and they are for providing wireless channel by mobile phone in each Feng Fang district of base station services and the Speech Communication between the base station.The base station is connected to mobile switching centre, and mobile switching centre provides the exchange of the telecommunications between the base station.GMSC (gateway mobile switching center) is connected between mobile switching centre and the public switched telephone network (PSTN), and the mobile phone by the cellular radio network service can be connected to the phone of being served by PSTN like this.
Except the voiceband telephone business that offers the mobile phone user by cellular radio network, offer the requirement of the Packet data service aspect of mobile data terminal in addition.Set up an international organization in April, 1992 and developed the standard that is used to provide Cellular Digital Packet Data (CDPD) business.In July, 1993, this international organization announced that the version 1.0 of version 1.0.CDPD technical specification that definition is used for the CDPD technical specification of the standard interface of CDPD network and function is cited for your guidance herein.
The CDPD net can be used as to be finished existing the overlapping of cellular radio network.CDPD demand of technical standard Mobile Data Base Station (MDBS) is for being called as the mobile data terminal service at station, mobile terminal (MES).MDBS is connected to mobile data intermediate system (MDIS), and the latter is connected to group data network (PDN) external common or special-purpose public, its sample MES can with stiff end station (FES) the exchange grouped data that is connected to PDN.
MDBS uses with the employed identical radio-frequency channel in speech base station that the mobile phone service is provided in identical service area to come and MES exchange grouped data.For avoiding the radio interference between packet data transmission and speech transmissions, MDBS must use the radio frequency reading device to scan voice channel, use to determine which voice channel is current by the speech base station that be the same area service, and its transceiver be tuned to only be that those current voice communications are not at the channel of use.Therefore, MDBS carries out " frequency hopping " between voice channel, to avoid those ongoing voice calls.
The frequency sweep of MDBS and retune the quite a large amount of processing of action need.And, be each frequency hopping meeting abort packet transfer of data that " avoiding " voice call is carried out, reduced the data throughput of CDPD net.Moreover, provide CDPD business because need expensive MDBS hardware, MDIS hardware and link MDBS hardware to the transmission facilities of MDIS hardware, so the cost of introducing the CDPD business is than desirable height, the place that the demand originally of CDPD business is restricted particularly.Reclaim its equipment investment fast if the CDPD service supplier is left sufficiently high paying price for this business or be limited to the business at heavy traffic area deployment CDPD, they will emit the risk of restriction CDPD Market Growth so.
In addition, by the border in the honeycomb district of MDBS service and not quite identical,, also be like this even when MDBS is set at identical position with the speech base station by the border in the honeycomb district of speech base station services.Border, honeycomb district is not quite identical to be because the handoff criteria between the honeycomb district is different for speech and packet data transmission.The inconsistent meeting on border, honeycomb district causes the too much interference at employed channel of Speech Communication and the employed interchannel of block data communication.
Summary of the invention
An object of the present invention is by CDPD equipment and the equipment that voice service is provided being carried out the integrated shortcoming that reduces or avoid some or all aforesaid CDPD net.
One aspect of the present invention provides integrated speech and the grouped data telecommunication system with a plurality of double mode channels, this system comprises: a plurality of transceivers, at least some transceiver can be used at least one double mode channel sending and receive voice service and at least some transceiver can be used at least one double mode channel, sending and the receiving block data business; And controller, be used to control a plurality of transceivers, so that give Speech Communication and block data communication double mode channel allocation, controller can be used for: maintenance is not assigned to the double mode queuing of the double mode channel of Speech Communication; In response to the requirement of voice channel to select double mode channel according to its position in double mode queuing; And give block data communication not selected any double mode channel allocation of distributing to Speech Communication.
Use has been avoided the scanning voice channel to determine which voice channel is the current needs that using, because this information has been available in controller the common control unit of speech and Packet data service.This has just been avoided the radio frequency frescan and has been the expense that drives the required processing resource of radio frequency frescan.In addition, common control unit can be designed to so that the mode allocated channel is to speech and Packet data service more orderly, so that be reduced to the number of times of the needed channel hopping of packet data traffic, this will be described in more detail below.Like this with regard to the throughput that improved grouped data and do not increase the obstruction of voice call.
Controller also can be used in response to the release to the double mode channel of distributing to Speech Communication, thereby this double mode channel is turned back to double mode queuing, and this double mode channel is redistributed to block data communication.Controller can queueing form works as last in, first out (LIFO) double mode queuing, so that the no abort packet data channel of the as much that is allowed with voice service amount condition is provided.
This system can also comprise a plurality of voice channels except a plurality of double mode channels, and this voice channel is specialized in Speech Communication and used.In this case, controller also can be used for keeping the speech queuing of idle voice channel.Controller can be used for when at least one voice channel is present in the speech queuing, in response to the request of voice channel is selected a channel from the speech queuing, and can be used for when not having voice channel in speech queuing, in response to the request of voice channel is required a channel from double mode queuing.In this manner, controller only distributes double mode channel to give audio call when not having voice channel available, under the condition of the grouped data throughput of maximum, the interruption of packet data transmission is minimized whereby.
In addition, because the interruption times of packet data transmission reduces, so the duration of performed swap operation has only less influence to the data throughput when each the interruption.Therefore, can loosen, thereby reduce the cost that hardware and software is realized the design constraint of this switching duration.
In order further to improve the grouped data throughput, controller can be used for when at least one double mode channel is assigned to Speech Communication the release in response to voice channel, thereby: select a double mode transceiver; The voice call of being served by selected double mode channel is switched to the voice channel that is discharged; Selected double mode channel is turned back in the double mode queuing; And selected double mode channel redistributed to block data communication.This switching only just can be activated when double mode queuing is empty, so that the switching times of voice call minimizes.Another kind of situation is that if there is any double mode channel to be assigned to Speech Communication, switching just can be activated, so that the maximization of grouped data throughput.Controller can make the operator be configured these handoff options.
Integrated speech and grouped data telecommunication system can be the cellular systems with a plurality of honeycomb district, and each subclass of a plurality of voice channels can be assigned to each honeycomb district, and each subclass of a plurality of double mode channels is assigned to each honeycomb district.Specifically, can be different for the frequency planning of double mode channel with frequency planning for voice channel.
Reduced interference between speech transmissions and packet data transmission for the use of the different frequency of channel double mode and speech planning, this can draw from the handoff algorithms between the employed different honeycomb district of speech and block data communication.
System also can comprise one or more Packet Data Channels of the usefulness of specializing in the grouped data operation, is in minimum level to guarantee the grouped data throughput, and no matter the voice service amount.In this case, as long as one or more Packet Data Channels are that above handoff options just may be forbidden in work.
One or more in a plurality of transceivers can be double mode transceivers, and it is used for sending and receiving voice service with voice mode, also is used for sending and the receiving block data business with packet data mode.In this case, controller is used in switch dual pattern transceiver between speech mode of operation and the grouped data mode of operation.
Like this, another aspect of the present invention provides integrated speech and the grouped data telecommunication system that comprises at least one dual-mode wireless transceiver and controller.The dual-mode wireless transceiver is used for sending and the reception voice service with voice mode, also is used for sending and the receiving block data business with packet data mode.Controller is used for switch dual pattern transceiver between speech mode of operation and grouped data mode of operation.
Each double mode transceiver can be implemented as and at least one transmitting set and at least one wireless combined processor of meeting sb. at the airport.Processor can be used for carrying out Speech Communication and carrying out block data communication with packet data mode with voice mode.
Because double mode transceiver and controller between speech and Packet data service by shared, so Packet data service can be with to relatively low increase cost that the needed software of Packet data service is provided and be added on the voice service.And Packet data service can be added to existing voice service and need not be connected to existing honeycomb district platform location antenna to additional radio-frequency apparatus, and does not interrupt existing voice service when such equipment is installed.Moreover, because be that speech and the required transceiver of Packet data service are to be placed on public base-station sites, so voice signal can be in the same place by multiplexing with packet data signals, so that send to base-station sites and send with shared multiplexed transmission link, so that transmission facilities cost minimization from base-station sites.
Another aspect of the present invention provides a kind of method of operating integrated speech and grouped data telecommunication system, and this system has a plurality of double mode channels, and each channel is used for carrying out Speech Communication and being used for carrying out block data communication with packet data mode with voice mode.This method comprises that maintenance is assigned to the double mode queuing of the double mode channel of block data communication, thereby select a double mode channel in response to request according to the position of double mode channel in double mode queuing, and give Speech Communication selected channel allocation for voice channel.

Describe in detail
Fig. 1 is the schematic block diagram of overlapping cdpd system 200 on cellular voice telephone system 100 according to the CDPD technical specification.
Cellular voice telephone system 100 comprises a plurality of speeches base station (VBS) 110 by a plurality of mobile switching centres (MSC) 120 interconnection.Each VBS110 comprises a plurality of speech radio receiving-transmitting units (VT) 112, and they are that (for example, the Speech Communication between MVT300) provides radio-frequency channel at VBS110 with by the mobile voice terminal in the honeycomb district of VBS110 service.
VBS110 is through multiplexed transmission link, and for example T1, E1 or other standard, or the multiplexed transmission link of professional format are connected to MSC120.MSC120 is provided at the telecommunications exchange between the VBS110.MSC120 comprises explorer (RM) 120, and it has controlled the distribution to the wireless channel that gives voice call.
Gateway MSC (GMSC) 130 is connected between MSC120 and the public switched telephone network (PSTN) 400, so that can be connected to the telephone set 500 of being served by PSTN400 by the MTV300 of cellular voice telephone system 100 services.
MDIS220 is connected to public or packet dedicated data network (for example PDN700), and the MES600 by cdpd system 200 services can be connected to the stiff end station of being served by PDN700 (for example FES800) like this.
The frequency sweep of MDBSs210 and return operation and load in conjunction with the sizable processing that the mobile needed overhead data transfer operation of packet data traffic from a channel to one other channel is equivalent on MDBSs210.And each frequency hopping of carrying out for " avoiding " voice call has been interrupted packet data transmission, has reduced the data throughput of cdpd system 200.Moreover, because need expensive MDBS hardware (comprising ST214), MDIS hardware and the MDIS hardware chaining to the transmission facilities of MDIS hardware so that CDPD to be provided business, so the cost of introducing the CDPD business is than desirable height, the place that the initial demand of CDPD business is restricted particularly.The border in the honeycomb district that serves by the border in the Feng Fang district of MDBS210 service with by speech base station VBS110 is not quite identical, even when MDBS is set at identical position with the speech base station, also is like this.Because the handoff criteria between the honeycomb district is different for speech and transmission of packet data.The inconsistent meeting on border, honeycomb district causes the too much interference at employed channel of Speech Communication and the employed interchannel of block data communication.
Fig. 2 is according to the integrated CDPD of embodiments of the invention and the schematic block diagram of cellular voice telephone system.Integrated system 900 comprises by a plurality of Nortel MTX
TMA plurality of dual-mode base stations (DMBSs) 910 that mobile switching centre (MTXs) 920 is interconnected.Each DMBS910 comprises a plurality of speech radio receiving-transmitting units (VT) 912, and they are that (for example, the Speech Communication between MVT300) provides the speech radio-frequency channel at DMBS910 with by the mobile voice terminal in the honeycomb district of DMBS910 service.
DMBSs910 is through multiplexed transmission link, and for example T1, E1 or other standard, or the multiplexed transmission link of professional format are connected to MTXs920.MTXs920 is provided at the telecommunications exchange between each DMBSs910.MTXs920 comprises explorer (RM) 922, and it has controlled the distribution to the wireless channel that gives voice call.
MTXs920 also finishes the function that an integrated system 900 is connected to the gateway MSC of public switched telephone network (PSTN) 400, so that can be connected to the telephone set 500 of being served by PSTN400 by the MVT300 of integrated system 900 services.
Each DMBS910 also comprises a plurality of dual-mode wireless transceivers (DMTs) 914.Fig. 3 is the schematic block diagram that shows DMT914 in greater detail.DMT914 comprises transmitting set 10, wireless receiver 20 and signal processor 30, and signal processor 30 comprises processing unit 32 and is used to store the instruction that will be carried out by processing unit and instructs needed memory of data 34 for carrying out these.Signal processor 30 receives speech and packet data signals from MTX920, and handles these signals for transmitting set 10 transmissions.Signal processor 30 also receives speech and packet data signals from wireless receiver 20, and handles these signals so that send to MTX920.Signal processor 30 receives control signal from RM922, so that at the voice mode that the signal processing that is suitable for voice signal is provided with switching signal processor 30 between the packet data mode of the signal processing that is suitable for packet data signals is provided.
Therefore, DMTs914 can be used under voice mode and MVTs300 exchange voice service by the honeycomb district of DMBS910 service, and can be used under packet data mode and MESs600 exchange Packet data service by the DMBSs910 service.The RMs922 of MTXs920 carries out work as controller, is used for switching DMTs914 between speech mode of operation and grouped data mode of operation, and this will be described in more detail below.
Each DMBS910 also comprises grouped data transceiver (PDT) 916, and it only is operated in packet data mode, specializes in and by the MESs600 exchange packet data signals of DMBSs910 service.
MTXs920 finishes the MDIS function of packet data transmission, and be connected to public or the packet dedicated data network (for example, PDN700), so that can be connected to (for example, FES800) by the stiff end station of PDNs700 service by the MESs600 of integrated system 900 service.
VTs912, DMTs914 and PDT916 are connected to the RMs922 of MTXs920 through one or more shared multiplexed transmission link.
The RM922 of each MTX920 keeps the VT queuing and for the DMT queuing by each MDBS910 of MTX920 service.The VT queuing comprises the identifier of idle VTs912.The DMT queuing comprises the current identifier that just is being operated in the DMT of packet data mode.
Fig. 4 is explanation is used for distributing the channel allocation algorithm of wireless channel by RMs922 in integrated system 900 the flow chart of first.When RM922 receives request to voice channel (or because MVT300 attempts to start a voice call, perhaps another terminal calling of MVT300 of attempting to start), RM922 at first checks the speech queuing, is idle to determine whether VTs912.If find idle VTs912 in the speech queuing, RM just distributes an idle VT912 to give voice call so, and upgrades the speech queuing.
If the speech queuing is empty, RM922 checks double mode queuing so, just is being operated in packet data mode to have determined whether DMTs914.(in packet data mode, the automatic configuration of RM922 is not assigned to any DMTs914 of voice call, so that transmitting grouped data as required.If) finding that DMTs914 is in double mode queuing, RM922 is with last in, first out (LIFO) principle distributes from double mode queuing DMTs914 so, and upgrades double mode queuing.
If speech queuing and double mode queuing all are empty, RM922 initiates the refusal to the voice channel request so.
Above-mentioned channel allocation algorithm is guaranteed to be interrupted providing before the Speech Communication in packet data transmission, to the use of the fullest of all voice channels.And, there is DMTs914 as much as possible to be used to non-abort packet transfer of data.In addition, PDT916 is often used in non-abort packet data communication.
The flow chart of Fig. 5 A second portion of channel allocation algorithm that is explanation when RM922 is set to complete double mode queuing switching construction.When the voice call by DMBS910 service was switched to another DMBS910, maybe when receiving when showing the release command that network or another terminal disconnected, voice channel was released when MTV300 disconnects.When voice channel was released, RM922 determined that the voice channel that is discharged still is to be provided by DMT914 by VT912.If the voice channel that is discharged is provided by DMT914, DMT914 is returned to double mode queuing and is switched to packet data mode so.
If the voice channel that is discharged is provided by VT912, the transceiver that is provided by the voice channel that discharges can be used for any other voice call now so.Specifically, provided the VT912 of the voice channel of release to can be current any voice call of just handling now in the past one voice channel was provided by the DMT914 that is operated in voice mode.This will make DMT914 can switch to packet data mode so that higher grouped data throughput to be provided.
Therefore, if the voice channel that discharges is provided by VT912, RM922 selects the current DMT914 that just is being operated in voice mode so, voice call is switched to the VT912 of the voice channel that release before is provided from selected DMT914, and a DMT914 who selects turned back to double mode queuing, and make the DMT914 of selection switch to packet data mode.
Advantageously, RM922 can be the voice call switching DMT914 that selection is assigned with at last from double mode queuing.RM922 can keep DMT speech queuing to be used for this purpose, when DMTs914 when packet data mode is switched to voice mode, make DMT914 enter the queuing of DMT speech.When the VTs912 that voice channel can be provided becomes when available, then RM922 can select DMT914 from this queuing by the LIFO principle.
Above-mentioned complete double mode switching be arranged in busy voice service amount the time can cause a large amount of voice call to switch, and this may be considered to unacceptable for some application.Reduce the switching activity of voice call in order to increase the grouped data throughput simultaneously, can promptly carry out the double mode switchover policy of part, replace the step of Fig. 5 A with the step of Fig. 5 B.According to the double mode switchover policy of part, voice call only just is switched to release from DMT914 when double mode queuing is empty VT912 (when all DMTs914 just are being operated in voice mode, does not so just have DMT914 to be used as the grouped data throughput.)
Aforesaid complete double mode switching and the double mode switching of part can realize as the option that the service supplier by operation integrated network 900 disposes at RM922.When the operability measurement showed that integrated system 900 is in the speech overload condition, switching option can be forbidden automatically.As long as at least one packet dedicated data channel (being provided by PDT916) remains on use, then switching option also can be disabled.
Fig. 6 shown for the integrated system of Fig. 2 separate double mode, the planning of grouped data and voice frequency.This frequency planning is based on specializes in 7 groups of channels (Va, Vb, Vc, Vd that Speech Communication is used, Ve, Vf and Vg), specialize in 7 groups of channel (PDa that block data communication is used, PDb, PDc, PDd, PDe, PDf and PDg), can be used for speech or be used for 7 groups of channel (DMa of block data communication, DMb, DMc, DMd, DMe, DMf and DMg), and suppose two VT912 in each Feng Fang district, two DMT914 and a PDT916.Reduced interference between speech transmissions and packet data transmission for the use of the frequency rule that separates of double mode channel, Packet Data Channel and voice channel, this is caused by handoff algorithms between the different Feng Fang district that is used for speech and block data communication.
In integrated system 900, by shared, Packet data service can be to be added on the voice service for the relatively low increase cost that the needed software of Packet data service is provided between speech and Packet data service for RM922 and DMTs914.And, the use of the public RM922 of speech and Packet data service has been avoided for the scanning voice channel to determine which voice channel is the current needs that using, because this information has been available in controller.This has just been avoided the radio frequency frescan 214 of CDPD network 200 and for driving the expense of the required processing resource of radio frequency frescan 214.In addition, public RM922 gives speech and Packet data service with mode allocated channel more orderly, so that be reduced to the number of times of the needed channel hopping of packet data traffic.Like this with regard to the throughput that improved grouped data and do not increase the obstruction of voice call.
In addition because the number of times of channel hopping reduces, so the duration of the swap operation of when each channel hopping, carrying out the data throughput is had only less influence.Therefore, can loosen, thereby reduce the cost that hardware and software is realized the design constraint of this switching duration.
The above embodiments can be modified and not deviate from principle of the present invention, and its scope is by below claim defined.
For example, integrated system 900 can have DMBSs910 more or less, a MTXs920 more or less than illustrated.Some or all MTXs920 can serve a plurality of DMBSs910.
Each DMBS910 can have the various transceiver type of different numbers.For example, as long as there are enough DMTs914 to be provided to satisfy the requirement of voice service amount, some or all DMBSs910 can not have VT912 so.
VT912 can be the DMTs914 that is configured to only be operated in voice mode by the operator.Similarly, PDTs918 can be the DMTs914 that is configured to only be operated in packet data mode by the operator.
VTs912 can be AMPS, TDMA or double mode AMPS/TDMA transceiver, and when at voice mode, DMTs914 can be operated in AMPS pattern or TDMA pattern.DMTs914 even can be " three-mode transceiver " selectively is operated in the AMPS pattern, TDMA pattern and packet data mode.If use the transceiver that selectively is operated in AMPS and these two voice modes of TDMA, so above-mentioned channel allocation algorithm will need correspondingly to be expanded.
In the place light relatively to the demand of mobile pocket data business, PDTs916 can be provided, all Packet data services are provided by DMTs914.In this case, partially or completely double mode changeover program is particularly advantageous as the means that increase the grouped data throughput.
The present invention also can be implemented on the network configuration with speech transceiver 112 separately and grouped data transceiver 212, these transceivers can be operated in identical radio-frequency channel shown in Figure 1 on, be from public queuing, to be assigned with as long as can be used to the radio-frequency channel of speech and block data communication.This just can realize by the common control unit that for example VT112 among Fig. 1 and PDT212 is connected to managing queueing.
In the above-described embodiment, provide a processor that separates 30 for each DMT914.Alternatively, processor 30 can be shared by a plurality of DMT914, or can provide separately processing unit 32 for each DMT914, and single memory 34 can be shared by a plurality of processor 34.
The embodiment that describes in detail above is particularly suitable for the application that voice service wherein is given the priority that is higher than Packet data service.Some application can give voice service amount and packet data traffic other relative priority, and this control algolithm can be modified the priority to be suitable for revising.Similarly, some is used may preferred other queuing management scheme except LIFO, for example FIFO (first in first out) or based on the queuing scheme of activity.
These and other of the embodiment that describes in detail above revised all below within the scope of the present invention of claim defined.
