Get back to Fig. 1, mobile radio station 102 can operate the GPS positional information for the position that is provided for identifying mobile radio station 102 to an entity of sending out request (for example, end call side 150 or urgent center 152).For this reason, can in wireless network 104, use a kind of in several different technologies.For a kind of technology, mobile radio station 102 during its idle mode of operation or during the audio call so that ask regularly or periodically, receive and storage GPS navigation categorical data in memory.The GPS navigation categorical data can be " original " navigation data or the data that alternatively obtain from original navigation data, can comprise GPS ephemeris (ephemeris) supplemental characteristic and/or GPS year calendar (almanac) supplemental characteristic (" therefore, term " navigation type " data).Can be by wireless network from location server 190 or alternatively directly from gps system 154 or with this dual mode reception GPS navigation categorical data.Notice location server/PDE 190 usefulness triangulation/trilateration process obtain the rough position of mobile radio station 102, gather supplementary with the GPS that obtains mobile radio station 102.Alternatively, can use the longitude of available this base station from the broadcast of base station that service is provided and latitude as the rough position of location server/PDE 190, gather supplementary with the GPS that obtains mobile radio station 102.
Subsequently, mobile radio station 102 is carried out the GPS process to obtain the GPS positional information.Particularly, the mobile radio station 102 GPS navigation categorical data that receives based on the last time and store in memory obtains GPS and gathers auxiliary data and/or sensitivity auxiliary data.GPS gather auxiliary data can comprise to suitably around gps satellite, Doppler frequency and the time delay window information data of labelling.The sensitivity auxiliary data comprises and will will carry out the fixing moment of GPS and be modulated to the prediction bit contents of the GPS navigation data on the gps signal.Next, mobile radio station 102 is so that utilize gps system 154 to carry out GPS to fix.During GPS is fixing, the GPS/ wireless receiver of mobile radio station 102 is tuned to the GPS frequency, to receive the gps signal from gps system 154.Mobile radio station 102 obtains the gps measurement data that is associated with mobile radio station 102 based on the gps signal that receives from gps system 154.Gps measurement data can be or comprise the GPS pseudo range data.
For example, during audio call, keep the Traffic Channel between mobile radio station 102 and the wireless network 104, so that can between the end user of mobile radio station 102 and end call side 150, carry out mobile communication.End call side 150 is associated with the telephone number that the end user of mobile radio station 102 has selected.End call side 150 can be any ordinary call side (for example, end user's family, friend or colleague) or the EC that alternatively is associated with " 911 " or other emergency number (such as, public safety answering point (or PSAP)).In certain moment during audio call, mobile radio station 102 is so that measure according to the base station signal of wireless network 104.Obtain these measurement results and be not for the rough position of mobile radio station 102 is provided, but for the use that combines with pseudorange, when only available GPS pseudorange is not enough to accurately determine the position, to improve positional precision.
Next, mobile radio station 102 is so that send measurement data and for the request of location positioning to location server or PDE 190.Can in response to from location server 190 or other request entity or by mobile radio station 102 spontaneously make (for example, by the telephone number of dialing (as, emergency numbers " 911 ") trigger) request, carry out the transmission of gps measurement data.Next, these data of location server/PDE 190 usefulness are calculated the position of mobile radio station 102 based on triangulation/trilateration.The positional information of mobile radio station 102 can be or comprise latitude, longitude and altitude information.Location server 190 can be in the situation that request is arranged or not have to ask directly be sent to end call side 150 with the positional information of the mobile radio station 102 that obtains.Alternatively, location server 190 can be sent to this positional information mobile radio station 102, and mobile radio station 102 can be sent to this positional information end call side 190.In alternative approach, be suitable for using in the situation of the own calculating location information of MS-only method at mobile radio station 102, do not need to come as mentioned above use location server/PDE 190.
Fig. 3 shows the flow chart of the illustrative method of being used by mobile communication equipment in processing urgency communication.The method can use one or more processors, memory, user interface and wireless transceiver thereof (for example, referring to Fig. 1-2) to carry out in conjunction with above-mentioned related system assembly by mobile device.The method can also be implemented in the computer program, described computer program comprises that computer-readable medium (for example, memory or computer disk), store the computer instruction that to be carried out by the one or more processors (for example, microprocessor) of mobile device in the described computer-readable medium.
Usually, as mentioned above, the method for Fig. 3 relate to mobile device via wireless network that set up with urgent call public safety answering point (PSAP) entity.If urgent call disconnects, then mobile device monitors to receive the incoming call message from the continuation urgent call of public safety answering point entity.In response to receiving this incoming call message, mobile device stop produce audible alarm and in the situation that does not detect any manual answering signal via its user interface automatic-answering back device from the continuation urgent call of public safety answering point entity.Therefore in continuing urgent call, obtained unavailable adequate information from initial urgent call.This information can comprise the geographical position that for example identifies mobile device, based on the positional information of GPS.In a concrete grammar, if this message of data indication indication that receives this incoming call message and this incoming call message in the time period after disconnecting is for continuing urgent call or automatic-answering back device, then mobile device automatic-answering back device should be called out.Receive this incoming call message outside this time period after disconnecting else if, if perhaps described data indication fails to indicate this incoming call message for continuing urgent call or automatic-answering back device, then the mobile device prevention is carried out automatic-answering back device to the calling that is associated with this incoming call message.
In begin block 300 beginning of Fig. 3, because the end user of mobile device may attempt carrying out audio call via cordless communication network, so mobile device is monitored its user interface to find user input signal (step 302 of Fig. 3).If processor detects call request (step 304 of Fig. 3) for audio call via user interface, then processor is identified this call request whether for (step 306 of Fig. 3) of urgent call.In order to identify this call request whether for urgent call, processor can be provided by the predetermined codes that the user inputted or selected (for example, 911 or similarly) of this calling, the predesignated subscriber input selection corresponding with urgent call (for example user selection mobile device provide " emergency call " button or icon) or the sensor output signal that is associated with mobile device (for example from mobile device " people falls down (man down) " signal).If this call request is for non-emergency call in step 306, then processor is carried out normal or conventional call establishment and the processing (step 308 of Fig. 3) for non-emergency call.
If as this call request of sign is for urgent call in step 306, then processor is so that initiate urgent call (step 318 of Fig. 3) via wireless transceiver to the PSAP entity.In the moment of call setup, ANI (ANI) or the caller-marking (calling part ID) that will be associated with mobile device are sent to PSAP entity (step 320 of Fig. 3).Ani information can be or comprise the number corresponding with the mobile logo symbol that identifies uniquely this mobile device.The PSAP entity receives ani information and incoming call is made reply, so that set up and keep between mobile device and the PSAP entity urgent call (step 322 of Fig. 3) via wireless network.During calling out, mobile device monitors to receive any location information request (for example, GPS position) (step 324 of Fig. 3) from the PSAP entity.If such as the location information request that receives in step 324 sign, then processor is so that send for the positional information corresponding with geographical position mobile device the PSAP entity.Can carry out at least in part this step by the technology of describing with Fig. 1.Alternatively, can spontaneously be carried out by mobile radio station 102 transmission (that is, after step 322, in step 324, not receiving in the situation of any request execution in step 326) of information.Therefore the PSAP entity can obtain the geographical position of mobile device.
If conditions permit suitably transmits all necessary information during the urgent call between mobile device and the PSAP entity, so that can suitably process this emergency.The example of adequate information comprise the end user of address, mobile device of geographical position (based on the geographical position of GPS), the position of mobile equipment of telephone number (ANI or calling part ID), the mobile radio station of mobile device and other relevant personnel name, help the end user to process information of this emergency etc.Yet this urgent call may hastily disconnect (step 328 of Fig. 3), so that suitably do not transmit all relevant informations.This urgent call may disconnect with multitude of different ways.For example, mobile device may be under the covering that is in wireless network during the urgent call, but mobile device may be reproduced and put (repositioned) or reorientation (relocated) subsequently, so that mobile device outside the coverage of wireless network, disconnects thereby cause calling out.As another example, urgent call may by the end user or the third party be casual or intentionally termination.
As described herein, use technology of the present disclosure, the PSAP entity can be to continue the form callback mobile device of urgent call.From this continuation urgent call of PSAP entity audio call that can be noiseless and/or automatic-answering back device.
If detect the disconnection of urgent call at step 328 processor of Fig. 3, then processor can arrange and running timer (step 330 of Fig. 3).Mobile device can use this timer that arranges in step 330 to limit from disconnecting the time period of beginning, and the PSAP entity can the callback mobile device in this time period.This time period is any position between 2-10 minute for example; Yet section can be suitable At All Other Times.
Then processor will return with the user input signal (step 302) of supervisory user interface and via wireless transceiver monitoring incoming call message (step 310).In optimization technique, about step 302, processor is forbidden any calling that the end user attempts from mobile device via wireless network (any follow-up urgent call of being undertaken by the end user may except) within the time period that timer limits.After timer expired, processing will allow the end user to carry out the calling of attempting from this mobile device.
After disconnecting, during via the wireless transceiver monitoring message, can receive the incoming call message for audio call (step 312 of Fig. 3) that mails to mobile device in step 310.This incoming call message can for after disconnecting from the continuation urgent call of PSAP entity.ANI or calling part ID that the utilization of PSAP entity is associated with mobile device are carried out this continuation urgent call.If do not receive incoming call message in step 312, then processor continues supervisory user input signal and radio message in step 302 and 310.
Yet if receive the incoming call message that mails to mobile device in step 312, whether processor identifies this incoming call message for needing mobile device to make (step 314 of Fig. 3) of the calling of noiseless and/or automatic-answering back device.In the first embodiment that is associated with step 314, if receive the incoming call message from the calling of PSAP entity in the time period that the timer that arranges limits in step 330, then processor so that in the situation that does not detect any manual answering signal via the user interface of mobile device this incoming call of automatic-answering back device (step 332 of Fig. 3).In addition, processor stops generation to be used for any audible alarm that this calling is reported to the police.Yet if receive this incoming call message outside the time period that timer limits, processor is so that carry out normal or standard call process (step 316 of Fig. 3) for this incoming call.For the standard call process, processor is typically so that produce audible alarm with this incoming call of reporting to the police to the end user at the mobile device place, and need processor (for example to detect the manual answering signal via user interface, detect braking, the rotation of mobile device shell or the slip of key or button) so that this calling is replied.
In the second embodiment that is associated with step 314, if it is to continue urgent call (namely that incoming call message comprises this calling of indication, for noiseless and/or automatic-answering back device) data indications, then at step 332 processor so that in the situation that does not detect any manual answering signal via the user interface of mobile device this incoming call of automatic-answering back device.In addition, processor stops generation to be used for any audible alarm that alarm is carried out in this calling.Referring to following discussion about Fig. 5.Yet, if this data indication fails to indicate this calling for continuing urgent call or noiseless automatic-answering back device, at step 316 processor to the normal or standard call process of this incoming call execution.Equally, in the standard call process, processor is typically so that produce audible alarm to end user's this incoming call of reporting to the police at the mobile device place, and needs processor to detect the manual answering signal so that this calling is replied via user interface.
In the 3rd embodiment that is associated with step 314, if receive the incoming call message from the calling of PSAP entity in the time period that the timer that arranges limits in step 330, and this incoming call message comprises that this calling of indication is to continue urgent call (namely, be used for noiseless and/or automatic-answering back device) the data indication, then in step 332 processor so that in the situation that does not detect any manual answering signal via the user interface of mobile device this incoming call of automatic-answering back device.In addition, processor stops generation to be used for any audible alarm that alarm is carried out in calling.Yet; if outside the time period that timer limits, receive this incoming call message; perhaps the data indication fails to indicate this calling for continuing urgent call or noiseless automatic-answering back device, then normal the or standard call process at step 316 processor to the incoming call execution.Thereby in the 3rd embodiment, the equipment of initiating automatic/silent answer not only depends on the time period but also depend on the data indicator variable.
In the 4th embodiment that is associated with step 314, if receive the incoming call message from the calling of PSAP entity within the time period that the timer that arranges limits in step 330, perhaps incoming call message comprises that this calling of indication is to continue urgent call (namely, for noiseless and/or automatic-answering back device) data indications, then at step 332 processor so that in the situation that does not detect any manual answering signal via the user interface of mobile device this incoming call of automatic-answering back device.In addition, processor stops generation to be used for any audible alarm that alarm is carried out in this calling.Yet; if outside the time period that timer limits, receive this incoming call message; and the data indication fails to indicate this calling for continuing urgent call or noiseless automatic-answering back device, then at step 316 processor so that for the normal or standard call process of this incoming call execution.Thereby in the 4th embodiment, time period and data indicator variable are independently, and have advantageously provided the specific installation that is used for initiating automatic/silent answer.After step 332, should continue in mobile device automatic-answering back device in the situation of urgent call, mobile device will as step 322 indicated keep this continuation urgent call.Provide such as flow chart, can come as required these steps of repetition.Continue urgent call and guarantee during the urgent call between mobile device and the PSAP entity, can suitably transmit the information that is necessary, so that can suitably deal with an urgent situation.
In a particular embodiment, the disconnection of urgent call is to be caused by the mobile device that situation outside the wireless network coverage occurs in step 328.After the situation, processor can identify the situation in the wireless network coverage that obtained outside the wireless network coverage that causes urgent call to disconnect.As response, processor is to wireless network transmissions message.It is again available to identify this mobile device that wireless network receives this message, and this message or corresponding message can be transferred into the PSAP entity to indicate mobile device again available.After this, as the response to this message, the PSAP entity is so that continue urgent call to mobile device.
Fig. 5 shows the illustrative of incoming call message 502 and describes, this incoming call message 502 can have data indication 506, described data indication 506 is in one or more data segments, whether indication incoming call message 502 is for the continuation urgent call (that is, noiseless/automatic-answering back device) of mobile device.In this embodiment, incoming call message 502 is radio or air-interface information of broadcasting by control or paging channel on wireless network.According to environment or content, incoming call message 502 can be or be called beep-page message, call control message or call setup message.If data indication 506 is bit indications, for example can to indicate incoming call be to continue urgent call (namely to bit " 1 ", calling for noiseless and/or automatic-answering back device), and bit " 0 " can to indicate incoming call be not to continue urgent call (that is, not for the calling of noiseless and/or automatic-answering back device).Incoming call message 506 also comprises other relevant information, as, identify uniquely the mobile logo symbol 504 of the mobile device that this incoming call will mail to.When message that monitoring is broadcasted, the processor of mobile device operates that the mobile logo symbol of mobile logo symbol 504 with himself storage compared, if coupling, then processor is carried out the action of describing about the step 314 of Fig. 3.
Notice, can also order mobile device voicelessly to reply this incoming call and do not produce the report to the police audible alarm of this calling to the end user for the identical data of automatic-answering back device indication 506.In alternative, usage data indication 506 indicates this incoming call to come automatic-answering back device by mobile device, but with indicating 506 different independent data to indicate to indicate whether voicelessly to reply this incoming call from data in the incoming call message.
Referring to Fig. 9, show the relevant portion of call flow diagram 900, so that the at once connection features that can use to be described in the call treatment of the present disclosure for the GSM/GPRS network.As describing in the GSM specification document, the GSM call control layer of call flow diagram 900 movement-based equipment is processed.Notice that MNCC is the acronym that the mobile network calls out control, MMCC is the acronym that control is called out in mobile management.This processing can be undertaken by the step 312,314,316 and 320 of Fig. 3.Begin in step 904 (U9 MT CALL CONFIRMED), mobile device receives common non-emergency call in step 904, mobile device proceeds to step 906 (DR (ALERT)) after MNCC_ALERT_REQ, then carry out step 908 (U7 CALL RECEIVED), then after MNCC_SETUP_RESP, carry out step 910 (DR (CONN)), then carry out step 912 (U8 CONNECTREQUEST).Yet, for continuing urgent call (perhaps noiseless/automatic call), then the step 902 (DR (CONN)) of handling process after step 904 (MTCALL CONFIRMED) proceeds directly to MNCC_SETUP_RESP carry out step 912 (U8 CONNECT REQUEST).Obviously, mobile device stops the step 906,908 and 910 of carrying out for continuing urgent call (that is, noiseless/automatic call), but carries out MNCC_SETUP_RESP and step 902.This is through with about the discussion of Fig. 9.
Preferably, the calling of this mobile device is carried out automatically and/or silent answer, and with that can provide for mobile device and irrelevant by other programmable data indication of mobile device use.In order to illustrate, Fig. 6 is that the illustrative of the memory 602 of mobile device is described, and can store programmable data indication 604 and 606 in this memory 602.Programmable data indication 604 is used for for the incoming call to mobile device audible alarm answer-mode or silent answer pattern being set, and programmable data indication 606 is used for for the incoming call to mobile device manual answer mode or autoanswer mode being set.The part able to programme of programmable data indication 604 and 606 is that the end user can change these patterns when needed.The pattern of mobile device can control and/or select based on the user input signal that receives via the user input device of user interface to processor.User input device can be or comprise for example one or more buttons or the key of mobile device.In response to end user's locking key or key, processor can provide for example selection between the pattern or switching.Preferably, processor is so that the graphic user interface (GUI) that provides in visual display unit or present, and described graphic user interface comprises GUI button or the menu list of selecting for the end user between different mode.
Equally, the indication of the programmable data of Fig. 6 is used for for the incoming call of mobile device audible alarm answer-mode or silent answer pattern being set.If the programmable data indication is the bit indication, then for example bit " 0 " can be indicated and will be used audible alarm answer-mode and bit " 1 " to use the silent answer pattern to incoming call by pointer for incoming call.Notice, can be used as the opposite bit definitions of alternative use or other bit configuration.For example, bit " 0 " can be indicated the equipment setting that will use for incoming call, and bit " 1 " can be indicated and will be used long-range silent answer control for incoming call.Typically, when the incoming call message of normal calling voice being called out when processor received and enables to mobile device and audible alarm answer-mode, processor was so that produce audible alarm with to this incoming call of end user's alarm via user interface.On the other hand, when the incoming call message of normal calling voice being called out when processor receives and enables to mobile device and silent answer pattern, processor stop via user interface produce be used for to this incoming call of end user's alarm any audible alarm.Yet, if programmable data indication 606 is set to enable the audible alarm answer-mode, but the incoming call message that calling voice is called out has the data indications (for example referring to Fig. 5) of replying for noiseless (automatically), and then processor still stops via the user interface generation for any audible alarm to this incoming call of end user's alarm.For an example truth table logic of this function, referring to following table 1.
