The present invention relates to be used to implement the equipment and the method for mobile communication.More specifically, the present invention relates to a kind of honeycomb subsystem of novelty, the zone of the service that this system provides similar the honeycomb valuably and mobile communication solution that be easy to realize cheap and do not bear the expense of the standard cellular system of implementing full performance to needs.

Mobile communication is well-known in the art.A kind of mobile communication of finite form relates to the cordless telephone of prior art.In the cordless telephone system of prior art, each cordless telephone generally comprises an elementary cell and a wireless unit.In fact and with copper cash or optical fiber the elementary cell that generally is positioned at dwelling house or commercial office links public switched telephone network (PSTN) usually.In order to discern each cordless telephone uniquely in common network, each cordless telephone is relevant with a telephone number particularly.

And the elementary cell of each cordless telephone is relevant with its wireless unit particularly and communicate with wireless method and wireless unit again.As long as the user of the wireless unit of prior art stays in the limited range of relevant elementary cell (because in the wireless technology in the intrinsic technical limitations most applications below 0.25 mile), can call out and from common network with wireless mode.

Yet the cordless telephone of prior art has some significant disadvantages.Except limited scope, the wireless technology of prior art also is restricted on the wireless element number that an elementary cell can be supported.General in the prior art cordless telephone each elementary cell one, no more than two mobile phone are provided.Because this restriction, the telephone service supplier still must can provide telephone service and regardless of whether wireless along arranging in telephone pole or the ditch that circuit makes to each dwelling house or commercial building.Therefore, though wireless unit seems what move to the user, realize that this serves desired network still is wired telephone network basically.

The user to the requirement and the construction of mobile communication service and the expense of keeping telephone foundation structure and increasing made many ISPs turn to other wireless technologys to be used for answering.Among existing technology, cellular technology is being rendered as tangible leader aspect the penetration power of market.Especially, utilize the cell phone system of the standard that is called global system for mobile communications (GSM) stably to win the ISP generally with this system of selecting as the realization cellular service.Universal its durability and the ability of support such as whole world roaming, phone mail, data service, auxiliary activities or the like a variety of characteristics of coming from of GSM standard.The information of relevant GSM standard can obtain in common range, and this paper quotes some GSM standard wherein as proof in appendix B.

Yet the GSM cellular network of the sort of mode or the enforcement of any cellular network are still quite expensive task for many groups (community).Though disclose the method and apparatus that be used for implementation cost effective cellular system among the common patent application WAVEP001.P that does not examine that mentions in the above, but have recognized that: the characteristic widely that provides such as the standard cellular network of implementing GSM standard is not provided for some group, particularly those groups in the developing or outlying district in the world.Such group's example comprises manufacturing equipment and outlying village in island, the outlying zone.Judging from the current situation, these groups must select between traditional cable network that requires practical basis structure widely to implement and the standardized cellular system such as existing GSM cellular system that many non-fundamental characteristics are provided, and wherein these many non-fundamental characteristics make that the standardization cellular system is too expensive so that are unpractical for these groups.

For these groups, desirable is a kind of honeycomb subsystem (CAS) of novelty, provide and the cellular service advantages associated, unlikely bearing implements to have the full payment that possibility is both impracticable optional standardization cellular network such as whole world roaming or data forwarding characteristic such as eliminating large-scale cable network, mobile phone mobility or the like.Yet, the honeycomb subsystem with any existing wired PSTN network seamless to work be important.And, because giving up that some are such may have the central office exchange of some existing forms (CO), so any communication system in this enforcement must be comprehensive so that allow group suitably to make an investment in existing C O hardware with existing C O, is important on software and other the telephony infrastructure.

And the honeycomb subsystem of wishing this novelty provides seamless basically call route selecting and subscriber information management between the cell phone of the wire telephone of common network and novel honeycomb Affiliate Network.In order further to reduce operation overhead, preferably manage the user and the metering data of novel honeycomb subsystem concentratedly by the public Subscriber Management System in same center of user who handles existing telephone user and metering data.

Also recognize: can use the cellular components that can extensively obtain and confirm, in above-mentioned novel honeycomb subsystem, realize the saving of surcharge such as GSM mobile handset, GSM base station transceiver and base station receiver hardware.Even it also is like this that this novel honeycomb subsystem implements to obtain its expense saving by the costliness of avoiding whole GSM characteristic groups basically.

The use of the used GSM part that confirms will not only reduce with development and test the relevant expense of new hardware, and proposition is easy to be updated to the novel honeycomb subsystem such as the omnicharacteristic cellular network of GSM network.For example, when group development and more completely cell global identity be provided with when need increasing, novel honeycomb subsystem is scalable not to be changed mobile phone or requires reconfiguring of most of network hardware for omnicharacteristic GSM cellular network requires the user.

The high desired characteristic of these and other of the shortcoming of utilizing this novel honeycomb subsystem to realize overcoming to relate to traditional cordless telephone system and omnicharacteristic cellular system, this at length describes in this specification text and accompanying drawing thereof.

The explanation of preferred embodiment

Fig. 1 represents the honeycomb subsystem (CAS) of a signal in one embodiment.In Fig. 1, show and comprise a plurality of base station transceivers (BTS) 202 and 204, base station controller (BSC) 206 and the attached controll block of honeycomb (CACB) 208 and CAS200.At hardware aspect, BSC206 and BTS202 and 204 are equal to each BSC and the BTS that is discussed substantially in the above-mentioned patent application WAVEP001.P that it is not examined together.The BSC of CAS and BTS form a base station sub-system (BSS).In one embodiment, the BSC of Fig. 1 and BTS implement above-mentioned GSM standard.Also have,, in whole specification, GSM standard is discussed for ease of explanation.But CAS of the present invention is not limited to any specific criteria, but and to revise arbitrary standard that CAS disclosed herein implements the standard of many extensive uses should be within those skilled in the art's ability.

Should remember: just schematically, each BSC206 can equip the BTS of bigger or smaller amounts to the CAS of Fig. 1, and the attached controll block of each honeycomb (CACB) 208 can be equipped the BSC of any amount.In one embodiment, each base station sub-system (BSS) has the mobile radio station (MS unit) that is used to handle limited quantity or the provided for radio resources management facility of cellular handset.BTS202 is expressed as and is in the wireless link with MS unit 220 and thereby is provided for handling the relevant resource of radio that goes to from the cellular communication of MS unit 220.Similarly, BTS204 is provided for handling and the relevant resource of radio from the cellular communication of MS unit 222 and 224.

By the mobile radio station of CAS200 management, for example the standard cellular mobile phone is preferably represented in MS unit 220,220 and 224.In one embodiment, the existing GSM cellular handset of they representatives.The use of standardization mobile phone advantageously allows the ISP, i.e. the people of those enforcements and/or management CAS200 is updated to CAS200 the omnicharacteristic cellular system of standard afterwards and does not require that the owner who has MS unit 220,222 and 224 now is by buying the mobile phone that new cell-phone replaces them.Equally, after being easy to, the use of BSC206 and BTS202 and 204 standard cellular hardware is updated to the omnicharacteristic cellular system of standard, if use BSC and the BTS of common unexamined patent application WAVEP001.P and WAVEP004.P and above-mentioned common unexamined patent WAVEP005.P, then in one embodiment, upgrade problem in just new software is packed into BSC and the BTS shell.

Use standard cellular technology implementation honeycomb subsystem of the present invention advantageously to allow thousands of the MS unit of each CAS of CAS network processes.This is especially like this in GSM embodiment, because the GSM technical specification is suitable for supporting a large amount of MS unit well.And, be that each MS unit of standard GSM mobile handset can have as many as above 20 kilometers or few scope to hundreds of rice in one embodiment.The ability of these enhancings represents than the scope of prior art cordless telephone system and capacity limit tangible advantage is arranged.When scope is at it during than low side, novel BAS advantageously provides and the random zone of designated mobile phone can be restricted to very zonule.In addition, if scope be at it than low side, as situation in one embodiment, can reduce through-put power, thereby relatively typically provide traditional omnicharacteristic cellular system of much bigger scope to provide additional expense to save.

In addition, CAS200 parts such as its BSC and BTS can be arranged in the geographic area to form CAS network's coverage area scope tactfully, when using, especially such such as disclosed low-power microgrid hole part in above-mentioned patent application WAVEP001.P and WAVEP004.P.In the time must changing, for example, when manufacturing works move its position, in fact have only some unit to move.On the contrary, the cable telephony system of enforcement prior art cordless telephone requires the big actual change of cable network for so changing.

CACB208 and common network 210 communicate by link 211, this common network 210 is represented public switched telephone network (PSTN) in one embodiment, link 211 preferably utilizes the SS7 signaling link, can certainly use the signaling link such as the other types of R2 or isdn signaling.Link 211 is used for CACB208 is coupled to the PSTN exchange resource.In one embodiment, the PSTN exchange resource is represented the switching network (209) of cable telephone network.In another embodiment, the PSTN exchange resource can be existing central office (CO207).From the common network viewpoint, CACB208 is the intact part of common network, is used as to the gateway of the MS unit of CAS.In fact, from public network, it is the extension of wired central office (CO) that the CAS network is equivalent to it.This extend to allow service supplier to provide telephone service to for example because economy or geographic factor cause CO to implement may be actual zone and the cell phone access is provided.The fact of communicating by letter between the BTS that finishes CAS in the honeycomb mode and its MS unit is transparent for the remainder of public network basically.

An operation and maintenance center (OMC) 212 relevant with public network 210 also is shown in Fig. 1.OMC212 in public network 210 communicates by letter with CACB208 through link 213, and this uses X.25 agreement in one embodiment.In certain embodiments, can use such as TCP/IP, ATM and similar other agreements.In typical PSTN network, OMC212 generally comprises and is used to manage such as user profile, charging, network operation and similarly one group of application of relevant user data.In typical PSTN network configuration, promptly in a PSTN network configuration of the cas system of the invention of not linking Fig. 1, OMC212 only manages relevant telephone user data of users.Their user data that uses the phone user of prior art cellular network generally to have to be handled by different Subscriber Management Systems promptly is specifically related to the user data of cellular system.Therefore, charging and the honeycomb supplier from the PSTN supplier generally separately handles in the prior art.

In the cas system of the invention of Fig. 1, the OMC212 of public network 210 provides user data management also for CAS client.As example, when a CAS potential user wishes to start MS unit 224 when professional, by OMC212 record such as charging address, charge information, selected type of service, relate to the user profile of the telephone number of MS unit 224.Shown in the back, the user profile subclass also resides in the Home Location Registry place (not shown in Figure 1) of CACB208 so that carry out call route selecting.In one embodiment, CACB208 utilizes its MS element keeps track phone to use and that information is offered public network 210, any expense that public network 210 uses by OMC212 management CAS network 200.Because user data and call charge service are all by the public network management, so these tasks are downloaded from the CAS manager valuably, this reduces valuably again and provides cellular services to the subscriber-related operation overhead of CAS.

In Fig. 1,210 connection generally is a wired connection from CACB208 to public network.Yet for some structure, connection can wirelessly be carried out, and for example can utilize microwave link.This disperse to open very much with remote environment in dispose advantageous particularly in the situation of CAS.In this case, the use of microwave link can provide significant saving, because it is avoided and the long expense relevant apart from laying-out.Being connected between CACB208 and BSC206 generally is wired connection, as being connected between BSC and its BTS also be wired connection.The honeycomb segment of cas system is present in BTS for example between BTS202 or BTS204 and the MS unit, because the foundation structure of handling the MS unit with wireless mode is present in BTS202 and 204, and to a certain extent, is present among the BSC206.Yet for public cable telephone network, the fact that MS unit and BSS communicate in the honeycomb mode is transparent basically.

For the calling between MS unit 222 and the MS unit 224, i.e. the calling that carry out this locality in cas system 200 can transmit the interconnection that data channel is connected on the CACB208 layer with in the mobile exchange station of more specifically equipping (MSC) in CACB208.Further details as for the enforcement of relevant MS can be consulted above-mentioned patent application WAVEP001.P.But, as disclosed in above-mentioned common unexamined patent S/NWAVEP004.P, can be on the lower level in the network hierarchy structure, such as on the BSC206 or the interconnection that on BTS204, connects.

Fig. 1 also illustrates wire telephone 214, and it links public cable telephone network in a usual manner.Do not think that wire telephone 214 is parts of CAS network 200.When wired telephone set 214 wish with CAS network 200 in MS unit such as MS unit 222 set up when calling out, public network by promptly being responsible for wire telephone 214 at two known end points of public network CO and CACB208 between carry out that Route Selection is next sends calling between wire telephone 214 and MS unit 222.CACB208 will seek advice from its database that is called Home Location Registry place (CASHLR) and find and allow its transmission to call out a bit to the information of MS unit 222.

In opposite direction, when MS unit 222 is wanted to call out wire telephone 214, MS unit 222 offers CACB208 with the telephone number of wire telephone 214, CACB208 for example with use the dialed number tree determine by the telephone number that MS unit 222 sends be not with CAS200 in a telephone number that the MS unit is relevant.CACB208 will ask public network it self and relate between the CO (not shown) of wire telephone 214 and send this calling, thus the call establishment path.

If there is another cas system to link public network 210, can dialing and links MS unit in the CAS200 of Fig. 1 in one of them MS unit, and it all is transparent that used mode is finished for public network 210 and original cas system.Because public network only sends between two known end points and calls out,, be that the fact of MS unit to MS unit is transparent now so call out no matter each end points is CACB, CO or similar other end points.

The major function piece of the CACB208 of Fig. 2 presentation graphs 1.In CACB208, provide an internal interface to public network (IPN) 250.This interface is inner, because as described in early time, think that CAS is an integral part of public network.IPN250 and public network communicate, and this communication utilizes the SS7 signaling in one embodiment.Fig. 2 also represents the Home Location Registry place (CAS HLR) 254 among the CACB208, is used to store relevant CAS user data of users.

In one embodiment, in the CAS network not in the regulation of CAS zone roam outside.In order further to reduce implementation cost, not roaming between the BTS of CAS network in another embodiment (basic CAS structure).The result, think that each user in the CAS network has fixing homing position, this is restricted to maybe can expand in the BTS zone of basic CAS structure and comprises many BTS, BSC area territory, one group of BSC area territory or even strengthen whole C AS network area in the structure.Also have, in one embodiment, for example might provide international roaming completely by in CACB208, implementing omnicharacteristic MSC.Note,, in the BTS zone, still have the mobility of certain degree even in its most restricted form.

About the information of user attaching position is put into the central public Subscriber Management System of public network and is offered CAS HLR254 through OMC212 and OMC interface block 252.When the user moves or when in the common network Subscriber Management System, upgrading customer service, also upgrade CASHLR254 similarly.OMC interface block 252 particularly communicates between CAS HLR254 wherein and the OMC212 at CACB208.In one embodiment, OMC interface 252 is implemented in the X.25 agreement of communicating by letter between CACB208 and the OMC212.

Attention: in one embodiment, CAS HLR254 needn't know that all user profile in the public Subscriber Management System of public network make CACB208 can carry out its routing function.Be desirably in one embodiment among the CAS HLR254 and only require route data.In another embodiment, whether desired unique information is to be authorized to use the resource of cas system to call out and the necessary data message of receipt of call for the MS unit that confirms appointment.As a result, have only the user profile of smaller subset in the public Subscriber Management System of public network to reside among the CASHLR254.Yet In yet another embodiment, CAS HLR254 can have relevant CAS user's all customer data.

Fig. 2 also illustrates TRAU piece 256.Attention: TRAU piece 256 is positioned at adjacent I PN250 and away from its prior art position, this is on mobile radio station one side of special mobile switching center (MSC) 258.Special-purpose MSC258 is identical with disclosed special-purpose MSC in above-mentioned common unexamined patent application WAVEP001.P basically.In one embodiment, each cas system has only a special-purpose MSC258.It is the fact of strict inner calling that TRAU does not automatically provide for the CAS network, promptly provides advantage at common unexamined patent application WAVEP001.P and WAVEP004.P institute's extensive discussions in the two in the fact of the calling between two MS unit of CAS network.

Small-sized C O260 also is provided alternatively, its groundwork be controlled at from or terminate in exchange between the calling on the MS unit of cas system.The further information of relevant Small-sized C O can be referring to above-mentioned common unexamined patent application (attorney docket WAVEP001.P).In one embodiment, do not provide Small-sized C O260.Under the sort of situation, the CAS network only provides through IPN250 and calls out connectivity to public network, wherein calls out exchange and takes place really.Special-purpose MSC258 also handles position updating request and other optional auxiliary activities.Because Small-sized C O needn't be provided, this CAS structure representative provides the mode of similar cellular services as the attached a kind of cheapness of existing wired public network.

If CACB links the CO among the PSTN, then this CO can be used for exchanging to and from the calling of the MS unit of CAS network.Advantageously, this CO even need not to be a honeycomb or GSM CO.In fact, expectation can be used such as AMPS, POTS, TABS, simulation CO or similar wired CO.When using communicating by letter between so non-GSM CO.CO and the CAS can utilize suitable interface to carry out, this interface may be a DSO interface in one embodiment.These require honeycomb CO, and for example the prior art cellular system of GSM CO is opposite.

The ability of utilizing Small-sized C O to implement the exchange in the CACB allows the more flexibility in the cas system enforcement and can cause significant saving.This characteristic is especially useful for the market of similar island country, and the public network central office may be away from the hundreds of miles in the village of implementing the CAS network in this island country.Use Small-sized C O to allow local call, promptly the calling this locality between the MS unit of CAS network exchanges, thus relax all-calls must return long distance to public network so that the bottleneck of appearance when exchanging.In order further to reduce and the relevant expense of enforcement cas system, can to utilize such as the Radio Link of microwave link and finish coupling between the exchange resource of CAS CACB and public wired network.

Yet no matter exchange is in the CAS site or gets back on the public network CO and finish exchange, the management of preferably concentrating user and charging task in one embodiment is so that the relevant expense of keeping user and/or billing database of minimizing CAS manager.The cheapness inlet that this characteristic advantageously makes service supplier have to enter mobile communication market and give the user with the introduction to business of the similar honeycomb of cheapness is in the future can be easily and be updated to the omnicharacteristic cellular services at an easy rate.

In Fig. 2, be assumed to and purpose be discussed and slight type CO is provided.Small-sized C O260 follow the tracks of the dialed number tree in case carry out call out exchange and also communicate with CAS HLR254 so as to confirm and ratify certain MS unit whether can carry out such as give before the calling, Conference Calling and similarly some assistant service.

Fig. 3 represents to reside in the schematically simple CAS customer data base on the HLR254.Should remember: CAS customer data base shown in Figure 3 is schematically and can changes, and in the CAS customer data base, has the route data of MS unit.Field 270 comprises the IMSI of the MS unit of CAS network, and field 272 comprises the telephone number that relates to the IMSI in the field 270, and field 274 comprises the homing position of the MS unit that its IMSI represents in field 270.In an embodiment of basic CAS structure, not roaming between BTS, the result, homing position can be reduced into specific BTS.Yet, can allow the MS unit of appointment to reside in a plurality of BTS band of position.When a plurality of BTS band of position was listed in the field 274 of specifying the MS unit, that MS unit can be roamed between these a plurality of BTS bands of position and still can think among scope.Field 276 its IMSI of expression are illustrated in the state of the MS unit in the field 270.The state of MS unit can comprise expression MS unit whether in field 274 in the indicated homing position, whether the MS unit is connected and test in time and similar sign.In field 278, exist in a supplementary service table alternatively, describe and give and the related MS of the IMSI unit of listing in the field 270.Attention: supplementary service does not provide to all CAS structures, and in some cases, the province of these business slightly is desirable to provide similar cellular services and advantageously realizes lower project (entry) expense as the attached service supplier of public cable telephone network.

Fig. 4 represents to comprise CACB208, BSC302 and 304 and BTS306,308 and 310 CAS network 300.In the example of Fig. 4, BTS306 is controlled by BSC202, and BTS308 and 310 is controlled by BSC304.Certainly, can provide the BSC of big or lesser amt and BTS.MS unit 370 to be controlled by BTS306 according to CAS network capacity and area requirement, MS unit 372 be controlled by BTS308, and MS unit 374 is controlled by BTS310.

Fig. 4 also illustrates the public wired network 320 on the CACB208 that is coupled to CAS network 300.Wire telephone 330 is coupled to public wired network 320 in a usual manner.

For the operation of CAS network 300 is described, Fig. 4 also illustrates a plurality of call paths 340 and 342.When MS unit 372 wished to call out wire telephone 330, this calling was in the outside of CAS network 300, and when promptly being an external call, 372 requests of MS unit are linked the connection of special-purpose MSC258 with it.In its request, MS unit 372 provides an initial address message (IAM) to give special-purpose MSC258, and the signaling data that is received by special-purpose MSC258 sends Small-sized C O260 subsequently to.Small-sized C O260 will recognize by search dial number tree: the telephone number of being dialed does not belong to a MS unit in the CAS network 300, the result, and Small-sized C O260 will transmit the internal interface that the IAM that is received gives public network (IPN) 250.IPN250 utilizes its command link to send IAM to public wired network 320, and this calls out and is sent to wire telephone 330 at last in a usual manner in public wired network 320.

In opposite direction, when the MS unit in wired telephone set 330 hope calling CAS networks 300, it will send its dialing numbers to public wired network 320.The number that to be dialed according to wire telephone 330, public wired network 320 for example will find Small-sized C O260 in six bit digital of 10 digit telephone number of dialing.In this case, Small-sized C O260 has relation with CACB208.Small-sized C O206 in CACB208 receives IAM, consulting CASHLR254 to determine and the related MS of the telephone number unit of dialing (this is included among the IAM).Small-sized C O260 also determines whether indicate it to can be used for accepting incoming call with the related MS location mode of dialing of telephone number in the database of CAS HLR254 or it is busy with another calling.

If target MS unit is suitable homing position zone (this defines in the database of CAS HLR254) but just busy, then Small-sized C O260 preferably returns a busy instruction and gives the CO of the calling in the public wired network.On the other hand, if if target MS location mode indicates it not have connection or MS not to respond its paging, for example the ring of reminder message indication will send back to the CO of the calling in the public network.Subsequently, the CO of calling can be suitably with relevant target MS unit status notification called telephone machine.Target MS location mode can be indicated when it for example roams out the homing position zone (this zone can be the same with single BTS in the basic CAS structure narrow or equally wide with the whole network of CAS that strengthens in the structure) of its permission its access failure or in time do not tested.Yet if target MS unit on and not being in a hurry, when this called out when user answer, this called out terminating (connection) in target MS unit.The step of call terminations on the MS unit of CAS network is after a while shown in Fig. 9 and 11.

For the calling of strictness in CAS network 300, for example Internal call between MS unit 370 and 374, process is slightly different.Suppose that MS unit 370 is MS unit of calling out at that time, and MS unit 374 is target MS unit.The connection of special-purpose MSC258 will at first be asked it is linked in MS unit 370, MS unit 370 provides an initial address message (IAM) to give special-purpose MSC258 subsequently, 370 signaling datas that receive send Small-sized C O260 to from the MS unit by special-purpose MSC258 then, and Small-sized C O260 sets the search dial number and recognizes: destination phone numbers belongs to the MS unit (being MS unit 374) in the CAS network 300.

Small-sized C O260 seeks advice from CAS HLR254 subsequently to determine target MS unit is whether MS unit 374 can be used for receipt of call (be on, in time check and be not in a hurry).If MS unit 374 can be used for receiving call, then Small-sized C O260 utilizes special-purpose MSC258 to come to carry out cross-coupled the connection between MS unit 370 and MS unit 374.Call path between MS unit 372 and the MS unit 374 is expressed as path 342 in Fig. 4.But, attention: if intelligence exchange (as disclosed in common unexamined patent application WAVEP004.P) is provided, between MS unit 370 and MS unit 374, can on the lower level in the network hierarchy structure, carry out cross-coupled the connection, for example between BAS302 and BSC304, carry out.Also have, unless MS unit 370 and 374 communicate with different rates, otherwise optional through the speed conversion of TRAU.In the present invention, because public network one side of TRAU unit from BTS one sidesway of MAS258 to it, so automatically require TRAU.This is different from the situation in the prior art cellular system: automatically TRAU is carried out in the calling between the MS unit in the call path part between MS unit and prior art MAS.

The flow format of the simplification of Fig. 5 is represented the step taked when the MS unit wishes to utilize the CASHLR registration office of CAS network to upgrade its position.Fig. 5 is from square 700, and on square 702, one is upgraded the MS unit and sends a position updating request to the BSC system through the BTS subsystem.Position updating request generally comprises the IMSI that upgrades the MS unit.In one embodiment, position updating request can comprise and be called the TMSI IMSI model of (for security reasons being used to replace the interim MSI of IMSI).The identifier of MS unit is discerned the MS unit that desired locations upgrades uniquely through IMSI or TMSI.

On square 704, the BSC subsystem will send the MS unit of position updating request in square 704 SCCP connection request sends the MSC subsystem to.In one embodiment, SCCP (SCCP) connection request is preferably represented the message that meets signaling system 7 (SS7) or the A interface between BSC on the CACB and special-purpose MSC function.Usually, the sealing of SCCP connection request is by upgrade the position updating request that the MS unit sends in square 702.Square 702 and 704 is set up mobile management (MM) dialogue.

In square 706, the MSC subsystem will be ratified to set up the SCCP CONNect Acknowledgement that MM connects and send to the BSC subsystem, now from MSC, the MSC subsystem sends one and handles the request of access to CAS HLR registration office in square 708, this request comprises the information that is included in the position updating request that is received on the square 702, so that determine by CAS HLR registration office whether the MS unit of just asking the position to be upgraded " authorizes ", promptly whether allow to use the CAS Internet resources, and upgrade the MS unit and whether roamed away from its rearmost position and need in the CASHLR registration office, upgrade.In basic CAS structure, a MS unit only just is authorized to use the CAS Internet resources when it is arranged in the BTS band of position that is assigned to it.Yet, in the embodiment of an enhancing, allow between BTS, to roam, and as long as specify a BTS just to think that this MS unit " authorizes " any one BTS that uses the CAS network.

In square 710, the access request that is received that sends is handled in CAS HLR registration office in square 708.In Fig. 6 of back, more fully explain square 710.In square 712, CAS HLR registration office sends a position to MAC and upgrades confirmation, and the resource whether the MS unit has licensed the CAS network is upgraded in indication.If upgrade the resource that the MS unit has been licensed the CAS network, then this position is upgraded and is confirmed preferably also to comprise indication executed position updated information whether in CAS HLR registration office.In determination block 714, whether (upgrading in the confirmation from the position that receives square 712) is determined to upgrade the MS unit and is authorized.Upgrade the resource that the MS unit has been licensed the CAS network if determine this in square 714, then the method advances to square 716, sends a position from MSC and upgrade the message of confirmation to BSC in square 716.

In square 720, send SCCP removing message from the MSC subsystem and talk with so that remove the MM that square 702 and square 740, is set up to the BSC subsystem.After square 720, the BSC that receives SCCP removing message in square 720 from first to last removes channel and gives renewal MS the unit.In square 724, the BSC that receives SCCP removing message in square 720 returns a removing and finishes message to MSC, and expression has been finished and removed the MM dialogue.In square 726, finish included step from the position that the MS unit upgrades by MSC.

On the other hand, if determine to upgrade the uncommitted use in MS unit CAS Internet resources in square 714, then the method advances to square 728-738 immediately so that remove SCCP or the MM dialogue.For example, if cas system implements (that is, not allowing roaming between the BTS) with basic structure and this MS unit finds in being different from a given BTS band of position of appointment, then this MS unit may not be authorized to.In square 728, the MSC subsystem sends a position and upgrades refuse information to the BSC subsystem, and expression can not be handled by upgrading the request that the MS unit upgrades the position.In square 730, the MSC subsystem sends a SCCP removing message and talks with so that begin to remove MM to the BSC subsystem.Subsequently, BSC from first to last removes channel and gives renewal MS the unit.In square 734, the BSC subsystem sends one and removes whole message to the MSC subsystem, and the MSS dialogue of setting up has been removed in expression in square 702 and 704.After this, the method advances to square 726, and the step of Fig. 5 finishes in square 726.

Fig. 6 is illustrated in the step of being taked when the access request that receives is handled in CAS HLR registration office in the square 710 of Fig. 5 with flowchart format.Fig. 6 begins on square 750, and the method advances to square 752 from square 750, and reception inserts request message by the processing of the MSC subsystem transmission of the square 708 of Fig. 5 in square 752.According to an aspect of the present invention, in square 754 all items in the CAS HLR registration office being checked the IMSI relevant with upgrading the MS unit upgrades the MS unit and whether has licensed the CAS Internet resources so that determine this.As described in early time,, then only authorize this MS unit to use the CAS Internet resources if a MS unit in basic CAS structure is arranged in the BTS band of position that is assigned to it.Yet, in the embodiment of an enhancing, allow to roam between the BTS, and as long as specify a BTS, think that this given MS unit " authorizes " resource of using the CAS network.Advantageously, can utilize this effective procedure to stop non-MS unit to use the CAS Internet resources.

Alternatively, square 754 may further include such as password checking, inquiry, mandate or similar some safety functions.Upgrade the use that the MS unit has been authorized the CAS Internet resources if determine this in square 756, this step advances to square 758, so that upgrade the CASHLR registration office if necessary.In square 758, check whether the identifier that upgrades the MS unit need upgrade with the position of checking it in receiving this CAS HLR registration office of handling the request of access.

If after the registral renewal of CAS HLR in square 758 or this renewal MS unit unauthorized uses the resource (in some structures and as determined in the square 756) of CAS network, the method advances to square 760, and CAS HLR registration office sends a position renewal confirmation to the MSC subsystem in square 760.As previous described at square 712 in conjunction with Fig. 5, whether this upgrades and confirms indication this upgrades whether the MS unit has licensed the resource of CAS network and it has been authorized if the position that is sent in square 760 upgrade to confirm indication, the registral renewal of executed CASHLR.In square 762, the step of Fig. 6 finishes.

Fig. 7 is illustrated in a MS unit from the CAS network internal step that each subsystem of CAS network is taked when calling out that starts with flowchart format.The step of Fig. 7 is from Fig. 5 (renewal of MS position) stopping place after square 716, and this is because the MS unit still needs to set up MM dialogue (square 702 to 706); Send a processing access request and be used for handling (square 708-712) to CAS HLR registration office; If the use unauthorized of CAS Internet resources forbids that then the MS unit uses CAS Internet resources (square 714,728,730 and 734); If the resource with authorizing the MS unit use CAS network that starts then allows this calling to proceed (square 714 and 716).

Call out rather than only ask the position to upgrade (situation of Fig. 5 promptly is such) because the step of Fig. 7 comprises the MS unit, so the message of bearing in the SCCP request of the square 704 of Fig. 5 is upgraded indication to MSC with positive call try rather than position.As those skilled in the art institute clearly, any Signalling method of CACB enforcement easy to use can be notified in the MS unit of just calling out.Also have, upgrade trial, when attempting a calling, generally needn't upgrade the position of the relevant MS of calling unit, CAS HLR registration office because the step of Fig. 7 is not the position.In this implementation content, when a calling is just being set up in a MS unit, do not carry out square 758 in one embodiment.In specific embodiment as herein described, licensed the CAS Internet resources if determine to call out the MS unit, then the method directly advances to square 760 from square 756.

The method advances to square 802 from square 800, calls out MS unit (through BTS and BSC) and send and comprise also that generally calling that destination phone numbers and indication will be set up is that speech, data, fax are set up message to MSC with similar information in square 802.The method advances to square 810 subsequently, and CAS HLR registration office sends a conversion and finishes calling to MSC in square 810, and this calling is the message of MAP type.The conversion that sends in square 810 is finished calling and is received from CAS HLR registration office by MSC in square 812.In square 814, MSC sends an initial address message (IAM) for Small-sized C O, and this IAM comprises destination phone numbers so that indicate it to wish to be connected to the specific objective telephone set in GSM implements.If as desired in one embodiment employing intelligence exchange, then it is that BTS, BSC, the MSC that the MSC among the CACB for example passes through among the CACB determines best cross-connection point or send this calling to public network.

In square 816, the approval of MSC response destination telephone is proceeded message to the calling of transmission of MS unit and is indicated this calling to carry out.In square 818, from Small-sized C O, send an address and finish message (ACM) and represent to receive that to MSC whole destination number (number of dialing) and this are called out has received its target.MSC reception ACM message also shows the successful prompting to the callee, and promptly destination telephone is just in ring.In square 820, the reception of the ACM message that MSC response is received in square 818 sends a reminder message for the MS unit so that notify this called Founder of this MS unit to be alerted and the ringer of call establishment MS unit.

In square 822, MSC sends an allocation request message to BSC so that allocated channel is used for the carrier actual voice/data channel and order BSC to utilize the channel that is distributed to set up calling for example on the A interface.The channel that the MS unit could send and receive its carrying data is called out in the channel representative that is distributed thereon.Should note: the step in the square 822 can be carried out with other steps of Fig. 7 are asynchronous.In one embodiment, just in time after MSC gave Small-sized C O transmission IAM message, MSC sent request for allocation to BSC (square 814).After receiving reminder message by the MS unit, the ringer circuit continuation ring of calling out on the MS unit receives this calling or calling party on-hook up to the callee, in this case, removes the MM dialogue once more in the mode of previous discussion.

In square 824, suppose that the callee receives the message that this calling and CACB send a response message (AMM) and represents that to MSC the callee replys this calling by receipt of call, in square 826, the reception of the ANM in the MSC response square 824 sends the connection acknowledge message to BSC and comes order BSC to connect reception (Incoming) path and calling (striking out) path.In square 834, calling party is connected from start to finish with the callee and calls out present at this moment thus.

Fig. 8 with flowchart format be illustrated in disconnect to call out in the step taked of each subsystem of CAS network.A calling is disconnected owing to calling party on-hook callee disconnects this calling.Should note: in one embodiment, when the MS unit in call path shifts out its specified home band of position, also may disconnect this calling.In CAS basic structure, the homing position zone is defined to and is assigned to the band of position of MS unit as the BTS of its homing position.In the CAS structure that strengthens, the homing position zone can comprise many BTS, a BSC scope, one group of BSC scope or even the structure that strengthens in whole C AS network.And, might for example provide international roaming completely in one embodiment by in CACB208, implementing omnicharacteristic MSC.

Calling when square 904 disconnects is disconnected in square 902 disconnections or callee when calling party.In square 902, MSC receives one and disconnects message from call out the MS unit, the on-hook or roamed out scope of expression calling party.On the other hand, in square 904, MSC receives one through Small-sized C O from the callee and disconnects message, shows callee's on-hook or also shifted out scope.In square 906, MSC sends for Small-sized C O will send the reception of callee's release message in response to the disconnection message in square 902 or the square 904 to.The callee can be in the CAS network or in public network, in this case, transmits this release message through internal interface and gives public network (IPN).In square 908, the callee sends to MSC through Small-sized C O and shows the release message that discharges permission.

In square 910 and 912, confirm to discharge and finish, in square 910, the release message that Small-sized C O response sends in square 908 receives a Release complete from MSC.Similarly, the release message that the MSC response sends in square 906 in square 912 receives Release complete from Small-sized C O.In square 914, all the relevant resources of calling that discharge and disconnect, for example TRAU, echo are eliminated or similar resource.

In square 916 and 918, MSC from first to last eliminates MM and talks with to calling out the MS unit.In square 916, MSC sends a SCCP to BSC and removes message so that begin the removing of MM dialogue.After this, BSC from first to last removes MM and talks with to calling out the MS unit.In square 918, BSC beams back SCCP that expression removed MM dialogue to MSC and removes and finish message.In square 920, finish the step of Fig. 8.

The step that Fig. 9 is illustrated in the CAS network with flowchart format MS unit receives as receiving element or taked during from calling that public network or another MS unit from the CAS network start.Fig. 9 is from square 950, and in square 952, MSC receives an initial address message (IAM) by Small-sized C O and is used for the calling of terminating on the MS unit of CAS network from network.If calling unit is another MS unit in the CAS network, then the IAM message that receives in square 952 is represented basically by call out the identical IAM message that the MS unit sends in the square 814 of Fig. 7.

In square 954, the conversion that MSC sends incoming call send the information service request to CAS HLR registration office in case the location by the represented MS unit of the telephone number in the IAM message.In one embodiment, square 954 comprise determine the target MS unit in the CAS network current location (for example, if this structure strengthens, then whether this MS unit has roamed the homing position zone away from it), the IMSI number of the corresponding telephone number that in IAM message, is received, by specific supplementary service of describing with mark MS unit or the like.

In square 956, send after the current location zone of localizing objects MS unit in square 954, CAS HLR registration office a conversion beep-page message to MSC so that request MSC utilizes its IMSI or some of them pattern paging target MS unit.In square 956, this conversion beep-page message sends to the MS unit and is currently located at wherein MSC (as determined after consulting CAS HLR registration office).In one embodiment, conversion transmission informational message and conversion beep-page message are all represented the MAP type of message.

In square 958, response receiving conversion beep-page message in square 956, MSC sends to suitable BSC with a paging request message.If it is uncertain which BSC band of position CAS HLR is positioned at for target MS unit, then receiving BSC may be more than 1 BSC.This is especially like this for the CAS structure that strengthens.In one embodiment, the definite BSC/BTS at place, target MS unit can (or utilize the MS unit to upgrade or because the MS unit is fixed to specific BTS homing position zone) be known in CAS HLR registration office.Respond this paging request, the page response of listening to from target MS unit is also waited in this BSC or a plurality of BSC paging target MS unit.

In square 960, if the paging request that sends in square 958 arrives target MS unit, target MS unit then sends a page response to BSC through BTS, and this response is sealed in the SCCP connection request subsequently, and BSC sends special-purpose MSC later on to.In one embodiment, if do not receive page response in during predetermined, think that then target MS unit roamed out scope or turn-offed and rejector circuit connects.

In square 962, response receives the SCCP connection message from BSC in square 960, and MSC returns a SCCP CONNect Acknowledgement message and gives BSC.In this mode, square 960 and 962 middle step are set up mobile management (MM) dialogue by target MS unit is associated with specific SCCP identifier.

In square 964, the target MS unit that utilizes page response (square 960) to respond goes through then.MSC sends one for CAS HLR registration office and handles access requested service request so that ratify this response target MS unit.In square 964, the target MS unit that the paging request sends to (square 958) also is verified and checks whether it is authorized to or is suitable for setting up the carrying data communication channel to target MS unit.In one embodiment, the step of handling from MSC to square the access request of 964 HLR can comprise that therebetween additional messages exchange is for example so that verify.

In square 966, MSC send one set up message to target MS unit so that set up a calling.Set up message and comprise call control information, for example desired type of service (for example data/speech/fax), and comprise the telephone number of the calling party that is used to set up calling alternatively.In square 967, MSC sends an AC address complete message (ACM) for Small-sized C O, shows that this network gone up to being enough to make the address (telephone number of for example, dialing) that the CAS network can localizing objects MS unit.In square 968, MSC receives a reminder message from target MS unit, represents that this MS unit confirmed to have attempted a calling and the ring of terminating on it and can begin.

In square 970, MSC sends an ACM message to Small-sized C O.Should note: though square 970 is shown after square 968 among Fig. 9, in fact square 970 can occur asynchronously with the square of Fig. 9.For example, square 970 can be as soon as possible immediately following occurring after square 952.

In square 972 and 974, distribute the carrying data channel resource between MS unit and the MSC.In square 972, MSC sends (will send target MS unit to) allocation request message so that distribute carrying data channel resource between MSC and BSC to BSC.This effect is to make target MS unit move to the carrying data channel of distribution from the channel that has only signaling (so far among Fig. 9 MS unit on this channel).

In square 974, MSC receives (BSC receives again) one and distributes acknowledgement message from target MS unit from BSC, confirms the reception and the successfully processing of the allocation request message that sent in square 972 by MSC.In square 974, notice MSC: carried out the Bearer Channel resource allocation of success, this allows the carrying data communication.In one aspect of the invention, square 972 and 974 comprises intelligent interconnection, and the Incoming path of the calling between two MS unit of CAS network and the actual interconnection between the out path are assigned to lower level in the hierarchy.As for the further information of relevant intelligent order connection aspect, can consult above-mentioned special-purpose application WAVEP004.P.

In square 978, MSC receives one and connects acknowledge message from target MS unit, indicate receiving target MS unit.The connection acknowledge message that response receives in square 978, MSC sends a response message (ANM) for Small-sized C O and indicates this calling unit (this calling unit can be another MS unit in public network or in the CAS network) in square 980: target MS answers by receipt of call the unit.In square 982, call out present at this moment.

From the CACB viewpoint, in the step of Figure 10 A, Figure 10 A begins on square 1000 by the procedural representation of a MS unit originating call of CAS network.In square 1002, Small-sized C O receives an initial address message (IAM) from special-purpose MSC.In one embodiment, IAM message generally comprises the destination phone numbers of being dialed.And in GSM implemented, all figure places of destination phone numbers generally arrived simultaneously.In other embodiments, numeral can once arrive one when positive dialing numbers.

In square 1004, find objective network, no matter it is PSTN or in the CAS of originating call network.In one embodiment, search the dialing tree by an one digit number according to ground and determine objective network so that determine out path.Next this process carries out in one of two branches according to call path.

If the callee is the wire telephone in the PSTN network, then process advances to square 1012, represents the PSTN path.In this case, CACB distributes suitable interface to be used for communicating with PSTN in square 1014, for example, and public network 250 internal interfaces of Fig. 4.Because destination telephone is positioned at the cellular zone outside, so be necessary to distribute speed conversion and echo to eliminate resource, promptly TRAU and echo eliminator if necessary, carry out in square 1020.

In square 0124, this process connects the call on the interface that distributes in square 1014, promptly on the internal interface of public network.Can recognize that as those skilled in the art square 1024 can also comprise the message of for example IAM, ACM, ANM (for example, seeing Fig. 7) and actual connection the from the suitable interface of special-purpose MSC to GSMC.After this, calling is carried out in square 1026.

If the target of calling out is in a MS unit from the CAS network area of originating call, then this process advances to square 1032, show that incoming call path loopback enters the same CACB of originating call, and should be by the MSC of this CACB or the actual interconnection of carrying data channel by another functional block inside of for example BSC, BTS, further down to hierarchy (if as in common unexamined patent application WAVEP004.P public cross-coupled words of employing intelligence).

In order to finish an incoming call, in square 1036, send IAM message.This IAM message is not sending on the internal network interface but is sending to a process so that end call in CACB.Particularly, the IAM that sends in square 1036 is received by the process that stops incoming call in the square 1102 of Figure 11.

In one embodiment, IAM message can comprise that the express possibility message of CAS in the net kind of message that is different from standard I AM message of additional information generally sends outside the CAS net.In one embodiment, IAM message can comprise additional information discern for example do not have that echo is eliminated, the different resource requirement of the traffic rate of no TRAU and MS unit.In some cases, some above-mentioned information also can be included in the ACM message.For example the enhancing message of IAM, ACM and ANM (for simplicity, being called IAM ', ACM ' and ANM ') can be used for the intelligent interconnection and the TRAU of embodiment such as call path.As for the discussion more comprehensively of the use that strengthens message, can consult above-mentioned common unexamined patent application WAVEP004.P.

In square 1038, originating call receives an ACM (AC address complete message) with the process of sending IAM message from the process that stops Figure 11 calling in square 1036.Particularly, this ACM is from the square 1118 of Figure 11.In square 1039, connect out and Incoming Bearer Channel together.In square 1039, if necessary, also utilize for example any desired internal work function (IWF) of TRAU, echo elimination.Also have, can be as intelligence interconnection of employing discussing among the above-mentioned common unexamined patent application WAVEP004.P and TRAU.

In square 1040, originating call sends ACM message for the MSC relevant with outbound call with the process that receives ACM message in square 1038.This process advances to the square 1042 of Figure 10 B from the square 1040 of Figure 10 A.

Figure 10 B is the continuation of Figure 10 A.Now referring to Figure 10 B, process receives an ANM from the out process of Figure 11 in square 1048.Particularly, from the square 1122 of Figure 11, receive ANM.This ANM is represented target MS unit answering call.In square 1050, Small-sized C O sends response message (ANM) in the square 1002 of Figure 10 A originating call and sends the relevant MSC in MS unit of IAM message.

From the CACB viewpoint, stopping in the step of procedural representation at Figure 11 of incoming call on the MS unit of CAS network.Figure 11 begins on square 110, and this process advances to square 1102 from square 110, in square 1102, receives an initial address message (IAM) from public network or the MS unit from the CAS network.If a MS unit originating call in CLLLS, then the IAM message that receives in square 1102 is the identical IAM message that sends from the square 1036 of Figure 10 A basically.In this case, think that this calling is Internal call, i.e. calling between two MS of same CAS network.In square 1104, Small-sized C O consulting CAS HLR registration office is so that the target MS unit in the CAS network of location.For example, therein target MS unit may roam away from its homing position zone promptly go beyond the scope or the situation that may be switched off under, square 1104 is essential.Do not connect if target MS unit, then finish afterwards during the signaling dialogue at the fixed time.

In square 1106, determine that its telephone number is encapsulated in the square 1102 target MS unit in the IAM message that receives and whether has licensed the CAS Internet resources and call out.If think that MS can not use, for example,, in square 1108, can generate a quick busy signal if it does or thinks and can not arrive that this process then advances to square 1108.

On the other hand, if determine that in square 1104 and 1106 target MS unit is currently located in its homing position zone, this program enters square 1110, and in square 1110, CACB specifies the internal work function as essential, for example echo eliminator.In one embodiment, when calling was started from public network, CACB also can distribution T RAU.

In square 1112, the IAM message that Small-sized C O will receive in square 1102 sends MSC to.In square 1114, by Small-sized C O receiver address full message (ACM) from MSC, the expression target call has been received full address.In square 1116, connect the carrying data channel to suitable interface from MSC, being communicated with between suitable interface and MSC realizes full-duplex communication.In square 1118, the ACM message that Small-sized C O will receive in square 1114 is sent to public network, or this ACM message is returned to the origination process of Figure 10 A in the situation of Internal call, and this receives in square 1038.

If the side's receipt of call on target MS unit, then MSC sends a response message (ANM) and gives Small-sized C O in square 1120.In square 1122, the ANM that Small-sized C O will receive in square 1120 sends public network to, or under the situation of Internal call, ANM is turned back to the origination process of Figure 10 B, this receives in square 1048, has received this calling so that show the callee.After this, process enters square 1124 as shown in figure 11, and this calling is underway in square 1124.

Though describe above-mentioned the present invention in detail in order to understand clear part, obviously can in the category of the claims of enclosing, put into practice some variation and modification.For example, though this paper mainly discusses the present invention in conjunction with gsm system, should note: the present invention so limits.Wish that especially honeycomb subsystem disclosed herein can implement in using the system of other specific protocols.Also have, though the present invention uses two communications between the MS unit that notion of the present invention is described, but should note: can be in plural MS unit, for example between 3,4 or more a plurality of MS unit, carry out Conference Calling, for the application that reaches disclosed equipment of that purpose and method also is among those skilled in the art's ability.Provide this openly, obviously can make up and replace and not depart from the scope of the present invention for the person of ordinary skill of the art and spirit.Therefore, the scope of the invention is not limited to the given specific example of this paper, but in the claims of enclosing, propose.
