Background technology
The present invention is directed to routing special number calls, more particularly, the present invention relates to according to the position of access point call alert is routed to the system and method for special number answering point from dual mode wireless communication device, this dual mode wireless communication device is that this dual mode wireless communication device communicates through this access point by unauthorized wireless network service.
As everyone knows, radio telephone gets poorly at the building internal work.Proposed a lot of solutions and solved this problem, but major part comprises the auxiliary equipment of the cell site that increases some forms and needs.This solution all is that cost is very high in installation and maintenance.
In the incoherent exploitation of carrying out before, the owner of office buildings, hotel, cafe, bookstore etc. and network operator for salesman, client or the two when building are inner use and radio data network is installed is inserted.By increasing one or more relatively inexpensive access point and router, these building have had the data network access with suitable relatively cost.
Recently, several radiotelephone installation manufacturer has introduced new dual-mode wireless phone.This new radio telephone runs on standard wireless network and unauthorized data network, and this standard wireless network comprises Global Systems for Mobile communications (GSM) network in the prior art, and this unauthorized data network is the internet for example.Radio telephone is connected to access point in aforesaid building, the hotel etc. by 802.11 (WiFi), bluetooth etc.This unauthorized networks service is often referred to unauthorized and moves access (UMA), and communicates by letter with the GSM network facilities in the mode that is similar to the networking telephone (VoIP) by data network.
This dual mode wireless communication device has solved the problem that wireless signal receives in the building.When the user of dual mode wireless communication device moves in the building with unauthorized wireless network outside the room, communication equipment from a network switch to another and very little or do not influence ongoing calling.Support the Telecom Facilities of these dual mode communication equipment to be based on the gsm wireless network configuration.
The gsm system of supporting UMA to insert has GSM mobile switching centre (MSC) in its core net, and this MSC control gsm system and switch call between other MSC's and PSTN (PSTN) various mobile units are as be known in the art.A plurality of base station controllers (BSC) connect between MSC and a plurality of base station (more generally being called " cell site ").The radio communication with mobile unit is realized in the base station, and is as be known in the art, and BSC provides the communication between base station first order control and realization base station and the MSC.
In order to support UMA, one or more UMA network controller (UNC) is connected to the identical mode of MSC with BSC and is connected to MSC.Each UNC also is connected to a plurality of access points by data network and realizes and the communicating by letter of bimodule mobile communication equipment.UNC connects data and converts GSM voice and signaling data to, and is connected to MSC by the interface and seems that UNC is exactly another BSC.About the more complete description of UMA, referring to
Www.umatechnology.org, its content all is incorporated into this with it by reference at this.
The problems of the prior art are when the caller uses dual mode wireless communication device in the unauthorized networks pattern, and not with call alert, emergency service call for example is routed to the device of the answering point of caller this locality according to parameter (for example position).Further, though be favourable according to the access point position routing special number calls, this route is not supported by any standard.Realize that further advantageously this route need not revise any standard, and in existing system, only need the minimum modification of route software and hardware.
Summary of the invention
When dual mode wireless communication device runs on unauthorized networks by according to one or more parameter the system and method that call alert is routed to the special number answering point having been solved this problem and has obtained technological progress in this area from calling out dual mode wireless communication device.According to an aspect of the present invention, parameter comprises the position of the access point that the calling Wireless Telecom Equipment is communicated by letter with it.According to another aspect of the present invention, the unauthorized that is connected to the GSM switching system moves the position that access (UMA) network controller (UNC) is stored each coupled access point.Advantageously, positional information is with the form or the storage of mode position form of X/Y coordinate.
In this illustrative examples, receive call alert at UNC from Service Access Point, for example emergency service call.UNC gives mobile switching centre (MSC) with this call-delivery, and MSC recognizes this calling and receives special route by the dialing special number according to predefined parameter.MSC is to GMLC (GMLC) inquiry route instruction.GMLC is to UNC inquiry service access point identity (AP-ID).UNC returns to GMLC with AP-ID.GMLC query subscriber database then, this database is mapped to their position separately with AP-ID, preferably with the form and the address information of X/Y coordinate.GMLC inquires about coordinate routing database (CRDB) with the X/Y coordinate and serves the position of this Service Access Point to determine which answering point.GMLC determines route instruction according to the answering point information that receives from CRDB, and route instruction is sent back MSC.Then this calling is passed to the answering point (for example public safety answering point (PSAP)) of the access point position of service order correspondence.Alternatively, before MSC is passed in calling or afterwards, UNC can advance AP-ID to GMLC.
In another illustrative examples, UNC communicates by letter with unauthorized location center (UPC), also communicates by letter with GMLC in this center.When UNC detects call alert, it inquires about pseudo-number with AP-ID to UPC.UPC returns pseudo-number and is used for the route purpose.UNC uses pseudo-number as call number urgent call to be passed to MSC.MSC uses pseudo-number to inquire about route instruction as keyword to GMLC.When GMLC receives pseudo-number, it with this number as the number related, and with pseudo-number inquiry UPC with UPC.UPC returns the street address that Mobile Directory Number (MDN), X/Y coordinate and the optional MSAG related with AP-ID verify to GMLC.GMLC is used for calling is routed to from MSC the instruction of the answering point of service response point position to the CRDB inquiry with the X/Y coordinate that comes from UPC then.GMLC determines route instruction according to the answering point information that receives from CRDB, and passes route instruction back MSC.MSC routes the call to the service response point according to routing iinformation.
According to still another embodiment of the invention, when UNC received call alert, it sent to MSC with MDN and AP-ID.MSC sends to MDN and AP-ID the emergency services network (ESN) of separating with wireless network.ESN selects the service response point according to AP-ID, and routes the call to corresponding service response point by ESN.
According to a further aspect of the invention, a kind of system and method that call alert is routed to the special number answering point from the calling dual mode wireless communication device that runs on unauthorized networks, wherein, use by wireless network as sub-district ID, call out the X/Y of mobile unit or access point identity (" AP-ID ") that the two uses, it geographical coordinate (is " X/Y " at this) or optionally, the two is all in same message or in the different message.AP-ID, it terrestrial coordinates or the two be combined in the described message, spell out the position grouping that has access point position rather than mobile unit.
According to prior art, mobile switching centre (MSC) sends subscriber location request (SLR) message to its GMLC (GMLC), and this message comprises sub-district ID, X/Y coordinate or the two.Yet according to an aspect of the present invention, AP-ID provides in SLR message.Advantageously, the MAC Address of access point is combined to the X/Y field of SLR message.And, that the mode type of message is set to define but currently do not have the value used.According to another aspect of the present invention, the X/Y of access point and MAC Address all are combined in the SLR message.In this embodiment, the mode type of message be set to another definition but currently do not have the value used.By this way, GMLC can discern access point position and when move, and correspondingly respond.

Embodiment
Fig. 1 has shown dual-mode wireless communications network 100, and an illustrative examples of the present invention is moved therein.Dual-mode wireless communications network 100 comprises according to the authorization portions of GSM standard operation and the unauthorized part of moving according to the UMA standard.Here describe this illustrative examples of the present invention in the bimodulus environment, the GSM/UMA Wireless Telecom Equipment is to the emergency service number answering point of Service Access Point region, and perhaps PSAP initiates special service and calls out (" 9-1-1 " calls out).Because need location-based parameter to local PSAP routing call, so describe present embodiment in the environment according to the access point position routing call, this access point is communicated by letter with the dual mode wireless communication device that runs on the unauthorized pattern.Those skilled in the art can understand how to revise the present invention to realize the voice or the data route of intended destination according to one or more parameter after this specification of study.Though describe the present invention according to emergency services or 9-1-1 call treatment, those skilled in the art can understand that the present invention can be applicable to any call alert after this specification of study.And, embodiments of the invention are described, wherein bimodule mobile communication equipment comprises mobile phone.It will be understood by those skilled in the art that the present invention can be applicable to any bimodule mobile communication equipment (including, but not limited to PDA, kneetop computer etc.).
In the environment of Fig. 1, the authorization portions of communication network 100 comprises a plurality of cell sites, by cell site 102,104 and 106 expressions.A plurality of cell sites are connected to a plurality of base station controllers, are represented by BSC108.All BSC comprise BSC 108, all are connected to GSM mobile switching centre (MSC) 110.Cell site 102,104 and 106, BSC 108 and MSC 110 are well known in the prior art, therefore are not described further.MSC 110 is connected to the selection router one 12 that routes the call to public safety answering point (PSAP), and its two also be well known in the prior art, therefore is not described further.
In order to understand importance of the present invention, the call alert that is undertaken by according to the authorization portions of the dual mode communication network 100 of prior art is described in the environment of the call flow of Fig. 2.Each step in the call flow of Fig. 2 is illustrated in the round parentheses after being described this step in Fig. 1.
The user who runs on the bimodule mobile communication equipment 114 of GSM pattern imports special number and presses the transmission key.In order to describe the present invention, special number is 9-1-1, north American emergency services special number.Mobile unit 114 sends call initiation message by wave point to the Serving cell website, this message comprises the number (9-1-1) dialled and the sign of mobile unit 114, this Serving cell website is a cell site 106 in the present embodiment, and this wave point is by 116 expressions of dashed communications channel.(202) sign of mobile unit Mobile Directory Number (MDN) normally, but also can be IMSI International Mobile Subscriber Identity (IMSI).In order to describe the present invention, represent MDN, IMSI or to any other mark of network unique identification mobile unit with MDN.
MSC 110 sends inquiry determining how route should be called out to GMLC (GMLC) 118, and the sub-district ID of MDN, X/Y and service cell site 106 is passed to GMLC 118.(208) this inquiry is the form of subscriber location request (SLR) message with standard definition.SLR message comprises the predefined arrangement of shape type field and X/Y coordinate subsequently.GSM standard has defined four kinds of mode types, wherein current in using four kinds two kinds.
If the X/Y coordinate confidence factor is very low, GMLC 118 optional (being illustrated by the broken lines) sends MDN and sub-district ID by MSC110 to Serving Mobile Location Center (SMLC) 120.(210,212) SMLC 120 determines to call out the X/Y coordinate of mobile unit 114 and by MSC 110 the X/Y coordinate is returned GMLC 118 once more.(214，216)
If confidence factor is very high at the beginning or SMLC 120 has redefined X/Y, GMLC 118 is applied to coordinate routing database (CRDB) 122 with the X/Y coordinate.(218) CRDB 122 comprises the mapping to PSAP of geographical position that wireless communication system 100 served.
For this illustrative examples, PSAP 124 serves the position around the cell site 106.GMLC 118 receives the sign of service PSAP.(220) GMLC 118 selects emergency services routed keyword (ESRK), and sends ESRK to MSC 110.(222) ESRK comprises in a plurality of predetermined numbers one, and this predetermined number indication selects router one 22 to be connected among a plurality of PSAP which.And as described below in order to pass to the PSAP of selection, GMLC 118 is related with selected ESRK with X/Y with MDN.
MSC 110 selects router one 12 giving as the call-delivery of call number as called-number and with ESRK with 9-1-1.(224) selection router one 12 use ESRK select the PSAP that it will connect from a plurality of PSAP, are PSAP 124 in this illustrative examples.Select router one 12 to give PSAP 124 with call-delivery, with ESRK as the call number transmission.(226)
PSAP 124 uses ESRK as keyword query automated location information (ALI) database 126.(228) ALI 126 is identified as the special number that requires more information with ESRK and with ESRK inquiry GMLC 118.(230) GMLC 118 returns the positional information and the MDN of mobile unit 114 to ALI126 (232), and ALI 126 passes to PSAP 124 with positional information and MDN successively.(234)
Forward the unauthorized situation of bimodule mobile communication network 100 below to, describe illustrative examples of the present invention now.The unauthorized situation of bimodule mobile communication network 100 comprises a plurality of access points, by access point 150 expressions, communicates by letter with UMA network controller (UNC) 158 by data network 154.UNC 158 provides the interface between data network 154 and the MSC 110.When bimodule mobile communication equipment 114 moves into the scope of access point 150, set up wireless connections by 160 expressions.The access point 150 of response wireless connections 160 and bimodulus mobile unit 114 is established to being connected of data network 154.This connection expands to UNC158, and it is set up with bimodulus mobile unit 114 and is similar to being connected of VoIP.UNC 158 is from being similar to the transition of communications of VoIP, and MSC 110 is presented in this calling is a normal wireless call as it.
Yet, can not handle in the identical mode of normal wireless phone emergency service call as described above from the emergency service call of the bimodule mobile communication equipment 114 that runs on the unauthorized pattern.Do not have the position of available bimodulus mobile unit 114 to come route to call out, if route this calling do not pass to the position of PSAP yet.Though might distribute cell site ID by each access point in the zone, cell site ID will be difficult to follow the tracks of.And cell site ID will run low very much.In addition, access point changes every day, and is perhaps more frequent, and this need be along with access point enters and withdraws from service and brings in constant renewal in MSC and GMLC.Therefore, the solution of this problem can not be imitated current special number wireless calling example as described above.Yet the call alert that comes from the UMA part of wireless network 100 must use existing utility and its operating software as much as possible, comprises standard message.
Now with the call flow of Fig. 3 with reference to the environment description of figure 1 illustrative examples of the present invention.The call flow steps of Fig. 3 is presented at described step ground and describes in the round parentheses afterwards.The user who runs on the bimodulus mobile unit 114 of UMA or unauthorized pattern passes through the input emergency service number, and for example 9-1-1 initiates emergency service call, and sends call set-up signals to access point 150.(302) access point 150 should be called out to UNC 158 routes by data network 154, transmit the number (9-1-1) that cries dialled and the sign of bimodulus mobile unit 114, this sign generally includes the MDN (as top definition) of this unit.(304)
UNC 158 identifies emergency service number and routes the call to MSC 110 at once, transmits the sub-district ID and the number (9-1-1) that cries of dialling of MDN, access point identity (AP-ID), UNC distribution.(306) MSC 110 identifies emergency service number, and knows that this calling needs special processing, with the same in the prior art.Yet unlike the prior art be that the sub-district ID of UNC 158 indication obtains this calling desired position information of route must be different with the prior art wireless calling.
9-1-1 in response to the sub-district ID with UNC 158 that arrives calls out, and MSC 110 sends routing inquiry (SLR message) to GMLC118, but the field of the SLR message that is to use is with of the prior art different.(308) particularly, MSC 110 uses the X/Y coordinate fields to send AP-ID to GMLC 118.Important, MSC 110 pattern field of " location estimation parameter " then is set to a kind of in two kinds of mode types that defined but do not had to use.This inquiry comprises the MDN and the AP-ID of bimodulus mobile unit 114.An example of this new usage of the type of message of definition is shown among Fig. 4.
GMLC 118 here with in the following illustrative examples discusses.Yet the present invention is not limited thereto.Those skilled in the art can understand that GMLC is an example in the common mobile location centre Chinese (MLC).Those skilled in the art use the present invention in how study can understand environment at the MLC of any kind after this specification.
Fig. 4 shows the schematic combination of the X/Y part 400 of " location estimation parameter " the GSM standard SLR message with new data.Shape type field 402 is set to " having the ellipsoid point of height ", this is defined by GSM standard but current also not use.Other fields are occupied by 12 of access point MAC Address.Because MAC Address has identified the access point of data network uniquely, so in this illustrative examples, use MAC Address.Those skilled in the art will appreciate that in study any numeral of unique identification access point or character string can use in the present invention after this specification.And, though might in field 402, use the recognized patterns type, access point ID might be misread as the X/Y value, this might make this calling be routed to wrong PSAP.Therefore, the preferred embodiments of the present invention are used and to have been defined but a kind of in two kinds of mode types of current nonrecognition.
Further, the X/Y of AP-ID, AP or the two can send in other parameters of SLR message.For example, AP-ID and X/Y can send in SLR-ArgExtension Container parameter.And, newer field can also be incorporated into and hold AP-ID and X/Y information in the standard.In addition, send in " the location estimation parameter " of " executing location response " message that AP-ID, X/Y coordinate or the two can be between UNC 158 and MSC 110.Those skilled in the art will appreciate that after this specification can use according to the present invention in study and can hold AP-ID, X/Y coordinate or any message parameter of the two, perhaps as initial data or according to compression algorithm.
Turn back to Fig. 1 and 3 now, GMLC 118 uses AP-ID as keyword query access point position database 162.(310) access point position database 162 returns X/Y coordinate and the street address (if any) relevant with AP-ID to GMLC 118.(312)
Next step, the routing iinformation that GMLC 118 uses the X/Y coordinate of access point 150 to inquire about about the PSAP that serves geographic area, access point 150 position to CRDB 122.(314) CRDB 122 returns the PSAP sign of serving zone, access point 150 position to GMLC 118, and GMLC 118 correspondingly selects ESRK and ESRK is routed to MSC 110.(318) MSC 110 routes the call to and selects router one 12, with ESRK as the call number transmission.(320) select router one 12 to use ESRK to select to serve the PSAP in the zone of access point, in the present embodiment, it is PSAP124, and should call out with this route.(322)
PSAP 124 receives this calling, and inquires about ALI 126 with ESRK.(324) ALI 126 is identified as special number with ESRK, and to the information of GMLC 118 inquiries about ESRK.(326) GMLC 118 returns caller's MDN, position (X/Y) and the street address (328) that optional MSAG confirms, these information are routed to PSAP 124.(330) by this way, the calling recipient at PSAP 124 has and typical radio calling identical or similar available information (that is, callback number and caller position).
Forward Fig. 5 now to, another illustrative examples of the present invention is shown in the environment of communication network 500.In this illustrative examples, access point position database 162 is directly connected to UNC 158, rather than is connected to GMLC 118.This illustrative examples may be desirable, for example, when access point position database 162 is frequent when changing, when perhaps changing by the personnel that can not visit the mobile communication network storehouse, perhaps the two.
The flow chart of Fig. 6 is described in the environment of Fig. 5 now.The user who runs on the bimodulus mobile unit 114 of UMA or unauthorized pattern passes through the input emergency service number, and for example 9-1-1 initiates emergency service call, and sends call set-up signals to access point 150.(602) access point 150 should be called out to UNC 158 routes by data network 154, transmit the number (9-1-1) that cries dialled and the sign of bimodulus mobile unit 114, this sign generally includes the MDN (as top definition) of this unit.(604)
UNC 158 identifies emergency service number, and AP-ID is sent to access point database 162, rather than should call out to MSC 110 routes.(606) access point database 162 returns the X/Y coordinate relevant with AP-ID to UNC 158.(608) UNC 158 routes the call to MSC 110 then, transmits sub-district ID, X/Y coordinate and the number (9-1-1) that cries of dialling of the distribution of MDN, AP-ID, UNC.(610)
Call out in response to the 9-1-1 with X/Y coordinate that arrives, MSC 110 sends routing inquiries (SLR message) to GMLC 118, but different with prior art and top illustrative examples, uses " location estimation parameter " field of SLR message.(612)
Fig. 7 shows the schematic combination of the X/Y part 700 of the standard SLR message " location estimation parameter " with new data according to this illustrative examples.Shape type field 702 is set to " polygon " and number of spots is set to " 3 ", this is that GSM standard has defined but currently do not use.In this illustrative examples, eight hytes 2 are occupied by width to 4, and eight hytes 5 are occupied by length to 7.Other fields are occupied by 12 of access point MAC Address.
Return Fig. 5 and 6 now, the routing iinformation that GMLC 118 uses the X/Y coordinate of access point 150 to inquire about about the PSAP that serves geographic area, access point 150 position to CRDB 122.(614) CRDB 122 returns the sign of the PSAP that serves access point 150 regions to GMLC 118, thereby GMLC 118 selects ESRK and ESRK is routed to MSC 110.(618) MSC 110 is to selecting router one 12 routes to call out, with ESRK as the call number transmission.(620) select router one 12 to use ESRK to select to serve the PSAP in the zone of access point, in the present embodiment, it is PSAP 124, thereby and route should call out.(622)
PSAP 124 receives this calling, and inquires about ALI 126 with ESRK.(624) ALI 126 is identified as special number with ESRK, and to the information of GMLC 118 inquiries about ESRK.(626) GMLC 118 returns caller's MDN, position (X/Y) and the street address (628) that optional MSAG confirms, these information are routed to PSAP 124.(630) by this way, the calling recipient at PSAP 124 has and typical radio calling identical or similar available information (that is, callback number and caller position).
Forward Fig. 8 now to, another aspect of the present invention is shown in the environment of communication network 800.Fig. 8 is similar to Fig. 5, and except in this illustrative examples, MSC 110 is connected to emergency services network (ESN) 802.ESN 802 comprises a plurality of switches, router etc., and they are connected to one of a plurality of destinations with one or more urgent call source.ESN 802 separates with PSTN usually.For convenience of explanation, ESN 802 and Ashish Patel submitted on October 25th, 2005, name is called the U.S. Provisional Patent Application No.60/760 of " the peer-entities network based on the route of parameter that is used for call alert ", the emergency services network of describing in 452 is identical or similar, this application is by AshishPatel now, Stephen Meer, Michael DeWeese and Carlton Smith submitted on July 14th, 2006, name is called the U.S. Patent application No.11457 of " the peer-entities network based on the route of parameter that is used for call alert ", 600.These patent applications have transferred assignee of the present invention, by reference its full content are incorporated into this at this.
In this illustrative examples, the CRDB 122 and the VoIP centre of location (VPC) the 804th, the part of ESN802.Basically, MSC 110 is to ESN 802 route emergency service calls and no matter what information MSC 110 receives.Therefore, for the GSM emergency service call, the MDN and the X/Y coordinate of MSC 110 routing call GSM mobile communication equipments.Just as will be described further, below, for the bimodule mobile communication equipment that runs on the unauthorized pattern, MSC 110 is to ESN 802 route MDN and AP-ID.The information that ESN 802 bases receive routes the call to selection router suitable among the PSTN by the network of oneself.
