Abstract
A method and system for implementing extension phone service within a mobile radio communication system. A plurality of mobile stations are assigned to a single subscriber number and a record maintained as to the current location of each mobile station. In response to a call received for the subscriber number, each mobile station is paged in the respective mobile switching center (MSC) in which it is currently located. The call is selectively routed to one of the mobile stations responding to the page request in accordance with preselected criteria, such as, the first mobile station to respond, the mobile station which is closest to the calling party etc.
Description
The multiple industrial standard that the cellular radio communication service has been accepted by the manufacturer and the network operator of cell system has been made definition and regulation.For example, EIA/TIA standard I S-41-B technical conditions regulation, calling in the cellular radio telecommunications is received specific mobile switching center (MSC) according to the position data of identification called mobile station (MS) at first, and position data then is stored in specific user's the attaching position register (HLR).Therefore, the paging of called mobile station is occurred in the MSC that calling connects, and if the position data that is stored in the HLR correct, the current state that uses and power that is in again of travelling carriage, then travelling carriage responds this paging, calling can be finished.
Another up-to-date EIA/TIA standard I S-53 is envisioned for the intrasystem travelling carriage of cell provides extension.In this kind configuration, intrasystem single directory number is with relevant with two or more travelling carriages, and each travelling carriage all has different travelling carriage identifiers (MIN) and different electronic serial numbers (ESN).So for the extension business is provided, HLR must keep independently block position data, be used for distributing each of two or more travelling carriages of same directory number.The plan of deciding cell extension business the inside by standard I S-53 is, when two or many extensions during simultaneously by paging, calling will be finished the extension of at first replying.If extension is arranged in the zone of same MSC service, each extension set by these extensions among the while paging MSC, can finish calling, finish calling according to IS-41-B then the extension set of at first replying to a directory number relevant with two or many extensions.Yet, being arranged on different MSC if connect one or more extension of same phone book number, the extension business of this configuration is just not all right.Promptly in present cell communication network, call can not be received the MSC more than simultaneously.
At a mobile radio communicaltions system, such as cell system or PCS Personal Communications System (PCS), it is all very useful to some different applications to be equipped with the extension business.For example, a cell mobile communication subscriber can require only to distribute to his directory number usefulness, but travelling carriage and call accepted on the removable/portable communication device under other occasion that still can be in being installed on vehicle when using.This will provide a kind of facility of optimum degree for above-mentioned user, and owing to only needing a directory number to reduce cost and having simplified service.In other cell extension service is used, only it is contemplated that such as the provider of delivery service or emergent ambulance service and to listen the calling of its service side with a directory number, but these callings or be connected to can the rapidest unit that service is provided, the unit that perhaps is connected to the personnel of in fact the most approaching request service is replied by the provider.A kind of like this configuration will improve this type of ISP's efficient greatly, and such as ambulance, under the situation of emergency service such as fire fighting truck, police car, service request can be sent to efficiently can provide the most above-mentioned emergency service unit of rapid response.
System of the present invention can realize the extension business with a kind of high efficiency and effective and efficient manner in a mobile radio communicaltions system.
On the one hand, the present invention distributes to two or more travelling carriages with a directory number, and each travelling carriage all has different MIN.When the HLR that has distributed this directory number receives calling, there is paging information to send to each MSC, wherein each extension travelling carriage all shows in the record that places HLR.These travelling carriages of paging in each MSC.Calling is connected to the residing MSC of the travelling carriage of at first replying this paging, and finishes the calling to this travelling carriage, might it be unique travelling carriage of replying of making, and may it be to make first of a plurality of travelling carriages of replying also.
On the other hand, the directory number that system of the present invention paging is exhaled simultaneously connects each travelling carriage extension set, but calls out the MSC that receives on the geography near calling party's travelling carriage.
Another aspect present invention resides in the mobile radio communicaltions system extension business is provided, and this system connects a plurality of travelling carriages, and each travelling carriage all has a sign separately, and a user number is arranged.The user number that a plurality of travelling carriage connects is passed in the calling that exchange is received.There is a parameter list to be retained in the database and thinks current each relevant travelling carriage of exchange that finds each travelling carriage with identification and user number.The Route Selection solicited message is delivered to the position that in the database each travelling carriage is decided to be current loca.Each travelling carriage is by the exchange paging of receiving above-mentioned request.After calling reception exchange receives that travelling carriage has been replied the indication of paging, send the travelling carriage that paging is replied in a plurality of travelling carriages with calling out to go to selectively.
In accordance with a further aspect of the present invention, call out and transfer in mobile radio communicaltions system, a user number can be relevant with one or more travelling carriages in this system.Each travelling carriage all has an independently travelling carriage identifier.From inquiry exchange receiving position solicited message, the user that a user number is arranged is called out in expression.It is relevant with a user number receiving this position request information whether judgement has more than one travelling carriage.Response only has judgement that user number is relevant of a travelling carriage and this, and this travelling carriage is finished calling.In response to the travelling carriage identifier and a judgement that user number is relevant that have more than one, the Route Selection solicited message that is used for each relevant travelling carriage identifier is delivered to the current location that is considered to travelling carriage point of living in.In response to each travelling carriage identifier of the position paging of receiving above-mentioned solicited message.Monitor that in a preselected time section paging of receiving from each paging replys, in this preselected time section, can not receive paging and reply, then correspondingly begin to carry out recovery routine.
Reply if only receive a paging, then reply travelling carriage and finish calling sending this.If reply, then make the call route selecting judgement, and will call out from inquiring that exchange is transferred to an office a plurality of travelling carriages according to this judgement according to predetermined standard from being received more than one paging by the travelling carriage of paging.
In order more completely to understand the present invention and further purpose and advantage, the present invention will be described in more detail below in conjunction with accompanying drawing.

Fig. 5 is according to the schematic diagram aspect the enforcement of setting up the extension business in cellular radio telecommunications of the present invention.
Referring to Fig. 1, it represents a traditional cellular radio telecommunications, and the present invention is relevant with it generally.Among Fig. 1, one arbitrarily the geographic area can be divided into a plurality of continuous radio coverage area or cell C1-C10.Only comprise 10 cells and a MSC although system shown in Figure 1 schematically shows, be appreciated that obviously the cell number in MSC in fact and the MSC can be more.
Relevant with each cell C1-C10 and be provided with wherein be a base station, it is as corresponding one among a plurality of base station B1-B10.As well known in the art, each base station B1-B10 comprises transmitter, receiver and base station controller.Expression base station B1-B10 is separately positioned on the center of each cell C1-C10 among Fig. 1, and has been equipped with omnidirectional antenna.Yet, in the cellular radio telecommunications of other configuration, base station B1-B10 can be arranged near the periphery, perhaps in other words can depart from the center of cell C1-C10, also can be with radio signal or omnidirectional or radiation cell C1-C10 directionally.Therefore, cellular radio telecommunications shown in Figure 1 only is used for explanation, and it is not a kind of restriction of conduct to all possible implementation method of cellular radio telecommunications of enforcement system of the present invention.
Continuation can have been found a plurality of travelling carriage M1-M10 referring to Fig. 1 in cell C1-C10.Moreover, 10 travelling carriages only are shown among Fig. 1, but the obvious in fact actual quantity of travelling carriage will be more, and will always greatly exceed the quantity of base station.In addition, though distinguish not shown travelling carriage M1-M10 in some of cell C1-C10, but obviously itself required of travelling carriage M1-M10 in fact all depended in the appearance in travelling carriage M1-M10 any one district in cell C1-C10 and not occurring, they can roam into another position from a position in cell, or roam into contiguous or adjacent district from a district, also can roam into another this type systematic in addition from the cellular radio telecommunications of a specific MSC service by other MSC services.
Each travelling carriage M1-M10 can both send or receive call by one or more base station B1-B10 and a mobile switching center MSC.Mobile switching center MSC is connected to each base station B1-B10 of diagram by communication link (for example cable), and be connected to fixing public switched telephone network PSTN (not shown), or comprise the similar fixed communication network of Integrated Service Digital Network function.Illustrated MSC also is connected to other MSC that constitutes the cellular radio telecommunications network.Between mobile switching center MSC and base station B1-B10, perhaps not being connected between mobile switching center MSC and PSTN or ISDN and other MSC all is illustrated among Fig. 1, but these all are known for those skilled in the art.Equally, comprise the mobile switching center more than in a cellular radio telecommunications, the technology that is connected to non-same group base station and is connected to other mobile switching center by cable or radio link mobile switching center that each is additional all is well-known.
Each cell C1-C10 is equipped with many audio frequency (or voice) passage and at least one and inserts (or control) passage, such as forward control channel (FOCC).The control channel utilization is sent to these travelling carriages and information Control that receives from these travelling carriages or the operation that monitors travelling carriage.This information can comprise incoming signal, and exhalation signal, paging signal, paging answer signal, location registration signal, voice-grade channel distribute and keep instruction.Control or voice-grade channel can be worked with the mode of analog or digital mode or both combinations.
Next referring to Fig. 2, it is illustrated in a part of block diagram according to the cellular radio telecommunications of switching incoming call in the system of EIA/TIA standard I S-41.In finishing the process of this type of calling, receive that at inquiry exchange 11 places the latter delivers to ownership exchange relevant with travelling carriage that this calling connects or attaching position register (HLR) 13 with location request signal 12 at the calling that the directory number of distributing to a travelling carriage is received.Ownership exchange or HLR consult its database, are assigned to the current physical location of the travelling carriage of called phone book number with decision, and according to the current location of called mobile station, concrete visit exchange or Visited Location Registor in the recognition system.Visited Location Registor or visit exchange 15 are delivered in Route Selection request 14.In more detail referring to information exchange figure shown in Figure 3, Visited Location Registor or visit exchange 15 are delivered to HLR13 with Route Selection request return results 16, and this information comprises interim routing number.HLR13 number is transferred to visit exchange 11 with the interim routing in the position requests return results information 17.Then, call out the current location that passes to travelling carriage 18, in this position it is carried out paging 19, if this travelling carriage is replied this paging then it is finished calling.
As shown in Figures 2 and 3, after visit exchange is passed in calling, the paging of IS-41 to travelling carriage just takes place to press.Like this, press the implementing like that in the trial of extension business of the functional definition of IS-53 in a cellular radio telecommunications, paging distributes the different travelling carriage of same phone book number simultaneously, unless two platforms all are positioned at same intra-exchange.Certainly, can at first calling be passed to and think a found exchange of first travelling carriage that is assigned to this directory number, paging is positioned at this travelling carriage of this exchange then, and wait for that it replys, only in the time can't receiving that paging is replied, just notice inquiry exchange will be called out to pass to again and be thought second the found exchange of another travelling carriage extension set that is assigned to this directory number.This method will be suitable bother, poor efficiency, and be not enough to satisfy the demand of cellular radio communication industry.
A kind of technology that is used for system of the present invention is that at first paging is to find a travelling carriage that is positioned at this exchange before calling being passed to visit exchange.Like this, if this travelling carriage is not answered this paging, access switch will be no longer passed in calling, to save actual spending and time.This technology is not described in the U.S. Patent applications of authorization at following two, and one is by John, the 07/756th, No. 487 application that people such as Hayes are that submit on September 25th, 1991, be entitled as " apparatus and method of calling out to the mobile phone user "; Another part by people such as NancyBuhl in April 27 nineteen ninety submit, be entitled as " in order in the wide area telephony network, to seek many exchange paging system of mobile phone " the 07/516th, No. 122 applications, these two patent applications have all transferred assignee of the present invention, and at this as the reference data.
In native system, when a visit exchange receives calling to a mobile subscriber, consult this user's HLR, with acquired information, find out MSC into its current location service.Then ask the above-mentioned travelling carriage of this MSC paging, use then about the indication that can find this travelling carriage and answer this HLR.If this travelling carriage has been replied this paging, just calling is passed to this MSC, to finish calling to this travelling carriage.This before transmit calling out the notion of paging travelling carriage be to be used for overcoming be the uncertainty of the position data that the user stored among the HLR at first, and farthest reduce and unnecessarily be sent to unsuitable position with calling out and with it about the operator circuit transit time.In system of the present invention, the notion of carrying out paging before transmit calling out has been extended and is provided effective extension service to implement in a cellular radio telephone system.
In native system, attaching position register is that each travelling carriage that is assigned to one group of travelling carriage of same phone book number is keeping position data individually.When receiving the calling of this directory number of terminating, the MSC that the request of inquiry exchange is indicated in the HLR position data carries out paging according to the MIN/ESN of each travelling carriage to it, and above-mentioned HLR position data is corresponding with the current location of each travelling carriage of being thought.Then, each MSC is the relevant travelling carriage of mode paging with roughly the same the time all, and no matter its be each other near or separately.Since by the travelling carriage of paging with each MIN/ESN sign, so all travelling carriages relevant with this directory number can both same MSC find and the while by paging.Equally, also can in different MSC, find all travelling carriages, and respectively at each travelling carriage of its corresponding M SC paging.Because each travelling carriage all is to come mark with a specific MIN/ESN combination or with particular data used on system's air interface, so sent to all separate processing of all requests of MSC by inquiry exchange.
After carrying out the paging request, wherein have travelling carriage by each MSC of paging to the report of inquiry exchange whether from being received that by the travelling carriage of paging paging replys.Then, inquiry exchange is delivered to calling and is received the MSC that paging is replied from the travelling carriage of institute's paging.Under more than the situation of a travelling carriage answer, can adopt different technology to come selective call will pass to which travelling carriage extension from the paging of its relevant MSC.Can utilize several different strategies to select by HLR.For example, inquiry exchange can be selected the MSC that at first sends affirmation to it is passed in calling, this affirmations represent by the travelling carriage of paging answered this paging also/or be on the voice-grade channel of this MSC.In addition, each travelling carriage that is assigned to as extension in one group of travelling carriage of same directory number can be allocated priority in advance, and HLR can handle multiple replying according to the order of priority of these distribution.But the order of priority permanent fixation that is distributed is given each extension, or according to the order of priority mapping algorithm of preliminary election they is changed.Moreover inquiry MSC can utilize the MSC spectroscopic analysis calling party's of the MSC that makes a start position, and utilizes the MSC spectroscopic analysis that has obtained the MSC that this paging replys to receive the position that paging is replied.These data can be used for to approaching most the travelling carriage transmission calling that making of calling party replied.Under such as the case of emergency that is used for ambulance, police car or the like extension, this will be a kind of useful especially calling switching scheme.
Next referring to flow chart shown in Figure 4, its expression one cover step can technology according to the present invention be implemented extension by this cover step in a cellular radio telecommunications.Among Fig. 4, system is in step 21 receiving position solicited message, and this information is relevant with the calling to user that given user number is arranged.In step 22, whether distinguish of system has more than one travelling carriage identifier (MIN) can be used for calling out user number with sending to.As not, system enters step 23, corresponding to distributing to the MIN of calling with the user number sent to, and according to for example step of EIA/TIAIS-41 regulation this travelling carriage is passed in calling at this.Yet, be assigned to calling with the user-phone book number of sending to if judge by travelling carriage more than one more than one MIN institute mark in step 22, then system enters step 24, HLR with directory number sends to VLR or visit MSC with the Route Selection solicited message of each MIN, and this VLR or visit MSC discerns the current location of conduct each travelling carriage corresponding with each MIN that is assigned to this user number in HLR database.In step 25, to each Route Selection solicited message, at relevant VLR/MSC paging each travelling carriage corresponding to each MIN, above-mentioned routing information is received from the inquiry exchange that sends multiple information by VLR/MSC then.In step 26, HLR monitors the response of being received that sends to several VLR/MSC from the Route Selection request in a selected period.
In step 26, if receiving, HLR is not sent to corresponding to the answer signal of each MIN identification as the Route Selection solicited message of each MSC of travelling carriage current location, system just enters step 27, and enable the recovering step that no paging is replied, as calling out switching another one number or sending no response signal to the calling party.Program finishes in step 28 afterwards.In step 26, if have only one to reply by HLR and receive, show and have only one to be sent a paging answer signal by the travelling carriage of paging by paging MSC and done response to it, system enters step 29 then, calling is sent to extension by the travelling carriage of the MIN institute mark of replying MSC place paging, and this MSC is this extension present located position.
In step 26, show that then system enters step 31 from having been received that by the travelling carriage of paging paging replys if HLR receives two or more information, at this to the Route Selection judgement of this specific user number evaluation based on preassigned.For example, system can enter step 32, at this MSC relevant with the travelling carriage with MIN is passed in calling, and this MSC at first replys paging after HLR sends the Route Selection request.In the case, system just delivers to calling in step 33 the travelling carriage extension of at first replying paging, having MIN, finishes in step 28 then.In addition, system can enter the criterion in step 34 beginning from the Route Selection judgement of step 31, transmit calling in this step according to certain order of priority that is assigned to each MIN, and each MIN is relevant with a plurality of extension travelling carriages that are assigned to user number.In step 35, receiving in a preferential order these to be replied after replying and making arrangements from each MIN being received MSC that paging replys.At last, in step 36, calling delivered to make that paging is replied and corresponding to the extension of priority for the highest MIN, program finishes in step 28 then.
Adopt another kind of method, Route Selection is adjudicated contained criterion and can be comprised and enter step 37 in the step 31, calls out and passes to the travelling carriage that approaches the calling subscriber most at this.In this case, system just enters step 38, calculates distance between inquiry exchange and the VLR/MSC at this, receives at this VLR/MSC and replys from the paging of mobile phone extension set, and this extension has and is used for receiving the MIN that its paging is replied.This can utilize a look-up table or realize according to the position of inquiry exchange and a kind of pre-defined algorithm that the position produced of each MSC.At last, calling is sent to the extension that approaches the calling subscriber most.A kind of call route selecting technology in above-mentioned back is specially adapted to such as class emergency service such as police car, ambulance, fire fighting trucks.
Next referring to Fig. 5, its table one block diagram/flow diagram wherein illustrates the process that realizes the extension business in a cellular radio telecommunications according to the present invention with a succession of step.As shown in Figure 4, in inlet MSC41 or inquiry exchange, to a particular telephone book number receipt of call, this number assignment is given a plurality of extensions, and each extension has different mark standards, such as different MIN, ESN or the like.Next, the corresponding HLR43 of directory number that will connect with this calling will be delivered in step 42 about the information of this calling.Suppose that to have two extension mobile station MSs 1 and MS2 to discern as the directory number that will connect with this calling relevant in HLR, in the database of the HLR of the current location of representing MS1 (travelling carriage 1) and MS2 (travelling carriage 2) respectively, in step 44 and 45 call information is passed to MSC146 and MSC247 equally then by HLR.Next, MSC1 is paging travelling carriage 1 in its position, and MSC2 is paging travelling carriage 2 in its position.As shown in the figure, do not receive that from travelling carriage 1 paging replys, but received that from travelling carriage 2 paging replys at MSC2 at MSC1.So just do not have routing information 48 to deliver to HLR43 from MSC1, routing number information 49 is then delivered to HLR43 from MSC2.This routing number is delivered to inlet MSC41 with information 51 by HLR43, after this, passes to MSC247 at step 52a-c to the incoming call of the MSC41 that enters the mouth, to finish the calling to travelling carriage 2.
Therefore, from foregoing description, can find, can in a cellular radio telecommunications, realize the extension business in a kind of rational and orderly mode according to description of the invention.The present invention provides optimized cellular radio extension business in this way, and the specific needs of the cellular radio communication user of this kind service can make up this business neatly as requested.
For example, Same Way that the invention described above adopted and principle also can be applied to the mobile radio of other type, such as that type of being recommended for Personal Communications Services (PCS).PCS can provide the calling that transmits in the mode that is similar to cellular radio telecommunications, but adopts other air interface technologies that is not considered as " cell technology " at present, such as CT2, CT2+, CT3, DECT or the like.Also can in this kind pcs system, implement in order to the native system of realizing the extension business.In other example, method of the invention described above and principle can be applied to so process, promptly according to detection to the conversation of delivering to a directory number, HLR searches another database that is called Service Control Point, to obtain a MIN form that is attached to directory number together with the standard of replying in order to the selection paging, order of priority, area data and any other the relevant information to each MIN.This SCP can be set together with HLR, perhaps can be used as a special node in the cell network.
Undoubtedly, can be well understood to principle of the present invention and structure from the above description.And shown in and described method and apparatus only be a kind of preferable scheme, under the situation that does not break away from the spirit and scope of the present invention that the application's claim limited, can also make various changes and conversion to this.
