Embodiment
The execution mode of accompanying drawing 1 graphic extension ip voice (VoIP) system 10, this system 10 is for providing packet-based voice-and-data service such as bimodule mobile communication device 12 such portable radios.Bimodulus mobile device 12 inserts VoIP system 10 via WAP (wireless access point) (WAP) 14 (for example, the compatible WAP of IEEE802.11 (WiFi), IEEE 802.16 (WiMax) or IEEE 802.20 (mobile broadband wireless access)).Bimodulus mobile device 12 directly or indirectly is coupled to VoIP system 10, for example, and by such as the such Packet Switch Data Network in internet (PSDN) 16.VoIP system 10 comprises the call processing server 18 that is used to manage the VoIP connection (comprising urgent call) that runs through VoIP system 10.
Bimodulus mobile device 12 and VoIP system 10 intercommunication control informations and packet-based communication data.In order to set up and control packet-based calling, bimodulus mobile device 12 and VoIP system 10 use signaling protocols, for example, and Session Initiation Protocol or H.323.For example, the communication processor 20 of the call processing server 18 of VoIP system 10 and bimodulus mobile device 12 uses the SIP (such as Java) that combines with client codes to control the disposal of the urgent call of being initiated by device 12.
Similarly, call processing server 18 is the packet-based communications of VoIP system 10 management.Call processing server 18 comprises hardware and/or software and it can be provided as independent server, a server farm or have the server farm (server farm) of distributed function.Call processing server 18 management devices communications, safeguard various mapping and decipher and open and shutoff device between communication channel.For example, call processing server 18 comprises the Call Agent 22 that is used to provide voip call signaling and controlled function.Call Agent 22 management and relevant signaling and the control flow of device that inserts VoIP system 10 for example, manage by initiation, termination or forwarded call.In the example of indefiniteness, Call Agent 22 can comprise and for example be used for by route and transmit the sip server (not shown) that SIP asks to provide SIP call signaling and controlled function.
In addition, call processing server 18 comprises application server 24, is used to carry out one or more application or services of can't help Call Agent 22 management, and for example, voice mail, videoconference and urgent call are disposed.Call processing server 18 carries out with media getaway controller/media gateway (MGC/MG) 26 alternately.MGC/MG 26 comprises and is used for call control logic and the hardware mutual with public switch telephone network (PSTN) 28.Thus, call processing server 18 inserts PSTN 28 via MGC/MG 26.
As the part of the packet-based connection of management in the VoIP system 10, call processing server 18 is handled the urgent call that receives from the various different devices (comprising portable radio, such as bimodulus mobile device 12) that are connected with system 10.The urgent call that is received by VoIP system 10 can comprise special-purpose emergency voice calls, 911 emergency voice calls, emergency text messages, urgent instant message or similar message.Call processing server 18 is routed to emergent answering point (EAP) 30 with received urgent call, promptly, default replies point in Quanzhou scope of appointment, such as public service answering point (PSAP), the emergent office in suitable this locality or other emergent answering point or dedicated emergency answering point, such as Onstar.In order to route emergency calls to suitable EAP, call processing server 18 obtains the information relevant with the position of packet-based calling, for example, terrestrial space or civic location information are such as latitude, longitude, height above sea level, street address, telephone number, building title etc.Call processing server 18 uses the suitable EAP of these position information confirmings to receive specific urgent call.
This paper has introduced several VoIP systems 10 that make can obtain the execution mode that positional information that the positional information relevant with the portable radio of connecting system 10 and use obtain routes emergency calls to suitable EAP.In one embodiment, call processing server 18 is filled and management database 34, and described database uses the positional information relevant with portable radio that WAP and EAP 30 are associated.Specifically, call processing server 18 uses the positional information relevant with portable radio as the apparent position of WAP and use this positional information that one or more EAP 30 and specific WAP are associated.Like this, when VoIP system 10 from known WAP (that is, the WAP of record being arranged in database) when receiving urgent call, call processing server 18 is confirmed the EAP that is associated with this WAP and is routed emergency calls to the EAP that is confirmed.
Accompanying drawing 2 graphic extensions are used to confirm WAP and the execution mode that will the positional information relevant with the WAP that is confirmed offers the processing logic of VoIP system 10.With before VoIP system 10 is connected, portable radio carries out WiMAX and inserts, and for example inserts wireless lan (wlan) (step 100).For example, bimodulus mobile device 12 uses the WLAN radio device 36 that is included in the device 12 to carry out the WiMAX access via WAP 14.WAP 14 implements to be used for determining whether bimodulus mobile device 12 is network insertion proof procedures of authorization device.
After inserting wireless broadband network, portable radio signs in in the VoIP system 10 or otherwise by VoIP system 10 checkings (step 102).After finishing checking, perhaps alternatively as the part of checking processing, portable radio sends the relevant identifier (step 104) with the WAP that rises (that is employed WAP when, device inserts VoIP system 10) to VoIP system 10.For example, bimodulus mobile device 12 provides the identifier relevant with the WAP 14 of rising.For VoIP system 10, each identifier is confirmed specific WAP uniquely, for example, and medium access control system (MAC) address, service set identifier (SSID) or Internet protocol (IP) address.Sending when request from VoIP system 10 or automatically, portable radio sends the positional information (step 106) relevant with mobile device to VoIP system 10.
The execution mode of the processing logic in the WAP information padding data storehouse 34 that provided by portable radio is provided in accompanying drawing 3 graphic extensions.When portable radio connect to insert VoIP system 10 via WiMAX, for example, during non-emergency call, this device signed in in the VoIP system 10 or otherwise to VoIP system 10 checkings it oneself (step 108).As the part of login process, portable radio to VoIP system 10 send and this device and VoIP system 10 communicate by the relevant identifier of WAP.For example, bimodulus mobile device 12 provides the identifier relevant with the WAP14 that rises to VoIP system 10.
Whether call processing server 18 checks rise WAP14 to VoIP system 10 known (step 110).WAP14 is known if rise, and then call processing server 18 is handled incoming call (step 112).On the contrary, if the WAP14 that rises is unknown, then VoIP system 10 obtains positional information (step 114) from bimodulus mobile device 12.The positional information of being obtained is as the approximation of the position of the WAP14 that rises.Use the updating location information database 34 (step 116) that is obtained then.Specifically, database 34 is mapped new WAP identifier with the one or more EAP 30 that serve the pairing geographic area of positional information relevant with the new WAP that confirms, as shown in Figure 4.In addition, VoIP system 10 can obtain positional information from a plurality of portable radios by same WAP connecting system 10.Call processing server 18 can use a plurality of positional informations of obtaining to become more meticulous or accurately locate the position of specific WAP.
Bimodulus mobile device 12 can obtain its position in various mode.For example, bimodulus mobile device 12 can comprise the GPS device (not shown) of the position that is used for determining it.Alternatively, bimodulus mobile device 12 can communicate with cellular network 38, obtains its position.For example, the cellular radio 40 that is included in the bimodulus mobile device 12 can be set up dedicated radio link with cellular network 38.In case connect, bimodulus mobile device 12 just by such as the enhancing tested time difference (EOTD), be subjected to cellular network deriving technology the assistant GPS or the tested time of advent poor (TDOA) to obtain its position.In another example again, the user of bimodulus mobile device 12 is input to positional information in the device, for example, and by in the keyboard that alphanumeric is input to device 12 or pass through voice command.
The such execution mode of accompanying drawing 5 graphic extensions: portable radio such as bimodulus mobile device 12 or VoIP system 10 install 42 in the scope (that is, and portable radio near being enough to set up the device of wireless connections between this device) obtain positional information.When bimodulus mobile device 12 can not be concluded its position, can use in scope and install the position that 42 positional informations that obtain are similar to bimodulus mobile device 12.Bimodulus mobile device 12 or device 42 obtains positional informations and this positional information is offered VoIP system 10 in the scope, or initiate the connection between the device 42 in VoIP system 10 and the scope.
In an example, bimodulus mobile device 12 device 42 in the scope obtains positional information and provides it to VoIP system 10.Thus, device 42 is unknown for VoIP system 10 in the scope.During urgent call, between the call processing server 18 of the communication processor 20 of bimodulus mobile device 12 and VoIP system 10, set up the SIP signaling and be connected.In addition, between VoIP system 10 and bimodulus mobile device 12, also set up media and be connected, be used for exchange message between communication processor 20 and call processing server 18.Be unknown in the position of judging bimodulus mobile device 12 or can not be when approximate, bimodulus mobile device 12 and scope be interior installs 42 communication processor 44 and sets up SIP and be connected.As a part that is connected with the SIP of device 42 in the scope, also to set up media and connect.Bimodulus mobile device 12 installs 42 request position information then in scope.Bimodulus mobile device 12 installs 42 in the scope and obtains positional information via being connected with the media of device between 42 in the scope.Bimodulus mobile device 12 offers VoIP system 10 via the connection of the media between dual-mode device 12 and the VoIP system 10 with this positional information then.
In another indefiniteness example, call processing server 18 is set up new SIP with the communication processor 44 of the interior device 42 of scope and is connected with media.What use was pre-existing in is connected with the media of device 42 in the scope, and bimodulus mobile device 12 can install 42 deriving means identifiers in scope, for example, and MAC Address, SSID, IP address or telephone number.Bimodulus mobile device 12 connects and will be transferred to VoIP system 10 from device 42 device identification of obtaining in the scope via the media that is pre-existing between system 10 and the dual-mode device 12 then.Call processing server 18 these device identification of use are come to set up new SIP between the device 42 in VoIP system 10 and scope and are connected with media.Thus, so can coming to install 42 in scope by newly-established media channel, call processing server 18 obtains positional information.Those of skill in the art recognize that call processing server 18 can install keeping with getting in touch with in one or more scopes when the urgent call of bimodulus mobile device 12 is connected.
In the example of another indefiniteness again, call processing server 18 communicates by device 12 in dual-mode device 12 and the scope.Specifically, dual-mode device 12 uses between dual-mode devices 12 and the VoIP system 10 and the SIP that sets up between the device 42 in dual-mode device 12 and scope and media are connected in VoIP system 10 and the scope route or transmission information between the device 42.In other words, bimodulus mobile device 12 can serve as in scope the terminal of setting up liaison between device 42 and the VoIP system 10.Thus, bimodulus mobile device 12 has played router or the logical effect that passes device, makes call processing server 18 can use with bimodulus mobile device 12 is pre-existing in and is connected to come that device 42 obtains positional information in the scope.
Accompanying drawing 6 graphic extensions are used for being sent to VoIP system 10 via WAP by portable radio the execution mode of the processing logic of urgent call.Portable radio connects the urgent call of initiating with VoIP system 10 (step 200) via WiMAX.For example, bimodulus mobile device 12 is initiated urgent call via the WiMAX connection that WAP 14 sets up.Portable radio sends and this device and VoIP system 10 communicate the identifier (step 202) that the WAP that passed through is associated to VoIP system 10.For example, bimodulus mobile device 12 provides the identifier relevant with the WAP 14 of rising.
The urgent call that the WAP/EAP relation that accompanying drawing 7 graphic extensions are used to use to be provided by database 34 receives VoIP system 10 is routed to the execution mode of the processing logic of suitable EAP.For example, after bimodulus mobile device 12 was by WAP 14 authentications that rise, the WiMAX that device 12 is set up via WAP 14 connects initiated urgent call (step 204).VoIP system 10 receives the identifier (step 206) that is associated with the WAP 14 that rises from bimodulus mobile device 12.Call processing server 18 uses inquiry of WAP identifier or the mining data storehouse 34 that receives from bimodulus mobile device 12 then, with the EAP (step 208) that confirms to be associated with the WAP 14 that rises.Call processing server 18 is delivered to the EAP (step 210) that is confirmed with urgent call, for example, and via PSTN 28 or emergency services network 32.
Accompanying drawing 8 graphic extensions are used for providing the portable radio of its position to send the execution mode of the processing logic of urgent call to VoIP system 10 to system 10 by the part as urgent call.Portable radio connects the urgent call of initiating with VoIP system 10 (step 300) via WiMAX.For example, bimodulus mobile device 12 is initiated urgent call via the WiMAX connection that WAP 14 sets up.Portable radio provides the positional information that is associated with portable radio (step 302) to VoIP system 10.For example, bimodulus mobile device 12 provides GPS draws, cellular network positional information that draw or that the user draws to VoIP system 10, and various these information all provide as described above.
Alternatively, accompanying drawing 9 graphic extensions are used for by provide the position of installing in the scope to send the execution mode of the processing logic of urgent call to VoIP system 10 as the portable radio of the approximation of portable radio position to system 10.Portable radio connects the urgent call of initiating with VoIP system 10 (step 304) via WiMAX.If portable radio can not be confirmed its position, device connect (step 306) in this portable radio and the scope then.For example, the communication processor 44 of device 42 is set up SIP and is connected with media in the communication processor 20 of bimodulus mobile device 12 and the scope.Portable radio then via with scope in be connected that device obtains positional information (step 308) in the scope between the device.Portable radio provides the positional information of installing in the scope of being obtained (step 310) via the connection that is caused by urgent call of being set up between system 10 and the portable radio to VoIP system 10.
The urgent call that accompanying drawing 10 graphic extensions are used to use the positional information that receives from the portable radio that sends urgent call that VoIP system 10 is received there is routed to the execution mode of the processing logic of suitable EAP.For example, after bimodulus mobile device 12 was by the WAP14 authentication that rises, device 12 sent urgent call (step 312) via the WiMAX connection that WAP 14 sets up.
Except receiving urgent call, VoIP system 10 is also seeked the opinion of that come or unsolicited by device 12 positional informations of obtaining (step 314) from 12 receptions of bimodulus mobile device.In an example, device 12 but before device 12 sends to VoIP system 10 with calling, obtains positional information after the user initiates urgent calls via device 12.In another example, device 12 provides the positional information of obtaining and storing by before the device 12.When pipe unit 12 does not obtain its position, the part of positional information as urgent call can be offered VoIP system 10 automatically or can provide positional information by device 12 when VoIP system 10 is asked.Call processing server 18 then urgent call is delivered to into the EAP (step 316) of the corresponding geographic area of unsolicited positional information service, for example, via PSTN 28 or emergency services network 32.
The urgent call that the positional information that accompanying drawing 11 graphic extensions are used to use the device in the scope of the portable radio that sends urgent call to receive there receives VoIP system 10 is routed to the execution mode of the processing logic of suitable EAP.According to this specific execution mode, portable radio can't obtain its position, but this portable radio is within the scope with the device that maybe can obtain positional information.During urgent call, call processing server 18 uses device obtains in the scope positional information conduct to send the approximation of position of the portable radio of urgent call.For example, the WiMAX set up via the WAP 14 that rises by bimodulus mobile device 12 of this processing logic connects and sends urgent call ＂ to Vo IP system 10 and begin ＂ (step 400).Except receiving urgent call, VoIP system 10 also from bimodulus mobile device 12 receive with scope in device 42 address informations that are associated and use this address information come with scope in install 42 connect (steps 402).VoIP system 10 then via in system 10 and the scope between the device 42 newly-established connection device 42 in the scope obtain positional information (step 404).Call processing server 18 with urgent call deliver to for scope in the EAP (step 406) of the positional information of installing corresponding geographic area service, for example, via PSTN 28 or emergency services network 32.
Accompanying drawing 12 graphic extensions are used for the execution mode of the processing logic of the incoming call urgent call that redirected VoIP system 10 receives in the positional information that system 10 can't obtain with urgent call is associated.This processing logic is received by carrying out the urgent call ＂ that the two mobile device (such as bimodulus mobile device 12) of honeycomb and radio communication sends by VoIP system 10 and begins ＂ (step 500).When receiving urgent call, call processing server 18 judges whether the position that is associated with urgent call is certifiable (step 502), for example, judges by in the execution mode of this paper introduction one or more.If the position is certifiable, then call processing server 18 routes emergency calls to suitable EAP (step 504).
If the position can not be confirmed, promptly, call processing server 18 be can not determine the position or the apparent position of bimodulus mobile device 12, then with emergency call redirection to another operator that can Gong select for use, such as the cellular carrier (step 506) that is associated with cellular network 38.In an example, call processing server 18 provides call redirection instruction to bimodulus mobile device 12 after the position of these server 18 decision makers 12 can not be confirmed, so just indicates this dual-mode device 12 to be redirected this urgent call.In another example, bimodulus mobile device 12 confirms that it can not obtain its position, and really as this moment calling is redirected to cellular network 38, and need be from the instruction of call processing server 18.
In bimodulus mobile device 12, communication processor 20 management emergency call redirection.When the position of bimodulus mobile device 12 can not be confirmed, communication processor 20 was set up the cellular communications channel with cellular network 38 like that shown in the step 508 of accompanying drawing 13.In an example, the call processing server 18 of VoIP system 10 provides call redirection instruction to bimodulus mobile device 12, impels communication processor 20 to come ＂ to be redirected the ＂ urgent call by send follow-up urgent call on cellular network 38.In another example, communication processor 20 confirms that it can not obtain the position of bimodulus mobile device 12, and really as this moment, generate and impel dual-mode device 12 ＂ to be redirected Internal call redirect instruction that ＂ calls out and need be from the instruction of call processing server 18.No matter how call redirection instruction produces, communication processor 20 all can come ＂ to be redirected the ＂ urgent call by send follow-up urgent call on cellular network 38 shown in the step 510 of accompanying drawing 13 in response to call redirection instruction like that.Thus, in the time of can not confirming in the position of bimodulus mobile device 12, provide service for urgent call by system's (not shown) based on honeycomb.Those of skill in the art recognize that if WLAN and cellular radio 36,40 are not seriously disturbed each other communication processor 20 can keep and set up cellular communications channel when the calling of VoIP system 10 is connected.
Under the situation of having grasped above-mentioned execution mode, be to be understood that, urgent call route in the VoIP system that this paper tells about provides a kind of VoIP system, for example system 10, this VoIP system constitute the urgent call that is used for sending by portable radio be routed to into the EAP of the corresponding geographic area of the apparent position of portable radio service.This VoIP system also constitute be used for calling lack be enough to make VoIP system that these callings are routed to the positional information of suitable EAP in, on cellular network, be redirected the urgent call that receives from the bimodulus mobile device.
