In addition, the character "/" in this document indicates that the former and latter related objects are in an "or" relationship.

The term "connected" in the embodiments of the present disclosure refers to various connection methods such as direct connection or indirect connection, so as to implement communication between devices.

The expression "network" and "system" appearing in the embodiments of the present disclosure are the same concept, and the communication system is a communication network. The term "connected" in the embodiments of the present disclosure refers to various connection manners, such as direct connection or indirect connection, for example, different devices are connected through a communication interface, and is not limited at all.

An emergency call is an emergency service that calls the police, fire or first aid departments when a person is in a critical situation, which is usually provided by the government. The number of the call for help telephone in each country may vary, but is generally composed of 3 digits for the help seeker to remember and dial. In order to obtain timely help, in addition to the help seeker clearly describing the situation and detailed location (which is sometimes difficult to achieve, such as the help seeker being too young, panic, deaf-mute, etc.), it is desirable to optimize the method of handling emergency calls (automatic location, etc.) from a system level. Such as the U.S. E911 system (and similarly european E112, eCall, etc.), 911 calls are routed to a Public Safety Answering Point (PSAP). At the PSAP, the call is answered by a professionally trained 9-1-1 dispatcher. The dispatcher's computer receives information from the telephone operator about the physical address (for a fixed telephone) or the geographical coordinates (for a mobile terminal) of the patron. The location information is used to send police, fire, medical and other services as needed. Therefore, it is very important for successful rescue to obtain the position of the help seeking person in time.

In order to locate a mobile terminal geographically, there are two general approaches, one is to use some form of radio location from the cellular network; the other is to use a global positioning system receiver (such as big dipper, GPS, Glonass, etc.), WLAN, bluetooth or a sensor, etc. built in the mobile phone.

In the related art, during the process of initiating an emergency call or during a call, the network initiates a positioning process to obtain the location of the mobile terminal, which may increase the response time of the emergency call because the process of obtaining the location requires additional interaction time.

The disclosure provides a location sharing method, which reports the location or auxiliary information of a mobile terminal before a network-initiated positioning process, thereby shortening response time.

Referring to fig. 2, fig. 2 is a flow chart illustrating a location sharing method.

The method is applied to a calling party user equipment 10, as shown in fig. 2, the method comprising:

step S11, a call setup message is output, the call setup message is used to request to establish a call connection with the called party user equipment 14, the call setup message includes the location information of the calling party user equipment 10.

Through the method, the embodiment of the disclosure can bear the position information of the calling party user equipment through the call establishment information, so that the position information of the calling party user equipment is reported when the call establishment information is output, the position information can be rapidly sent, and the communication quality is improved.

Referring to fig. 3, fig. 3 is a flowchart illustrating a location sharing method according to an embodiment of the disclosure.

In a possible implementation, as shown in fig. 3, before outputting the call setup message at step S11, the method may further include:

step S12, obtaining location information of the calling party user equipment 10;

step S13, when the called number of the called party user equipment 14 is an emergency service number or a pre-specified contact number, writing the location information of the calling party user equipment 10 into the call setup message.

Through the method, the embodiment of the disclosure can acquire the location information of the calling party user equipment before outputting the call setup message, so that when the called number of the called party user equipment is an emergency service number or a pre-designated contact number, the location information of the calling party user equipment is written into the call setup message, and thus, the location information can be reported quickly.

The location information may include various forms, such as at least one of latitude and longitude locations, geographic traffic locations, relative locations with respect to a reference location, and may also include measurement information, and the like.

In one example, the latitude and longitude location may be in the form of (east longitude X, north latitude Y), for example.

In one example, the geographic traffic location may be in the form of, for example, (xx province xx city xx district xx road xx number) or the like.

In one example, the relative position with respect to the reference position may be in the form of (at xx azimuth of xx building, distance xx), for example.

In one example, the measurement information may include, for example, measurement information of assisted positioning technologies (GPS, galileo, sbas, modernized-GPS, qzss, glonass, bds, etc.), and after obtaining the measurement information, the location of the calling user equipment may be estimated or converted to obtain an actual location, and the disclosure does not limit the type of the measurement information.

Of course, the above description is exemplary, and the embodiments of the present disclosure do not limit the specific form of the location information, which can be determined by those skilled in the art as needed.

In a possible implementation, the step S12 of obtaining the location information of the calling party user equipment 10 may include:

acquiring the position information of calling party user equipment from a position information storage space; or

And acquiring the position information of the calling party user equipment from the storage space of other application programs.

The embodiment of the present disclosure does not limit the source of the location information, the source of the location information may be various, a location information storage space may be preset, so as to store the location information of the calling party in the location information storage space, and also obtain the location information of the calling party user equipment 10 from the storage spaces of other application programs.

Through the method, the embodiment of the disclosure can quickly acquire the position information of the calling party user equipment.

It should be noted that the location sharing method proposed in the embodiment of the present disclosure has no special requirement on the dialed number (called party), for example, the called party may be an emergency service number or a general number.

For emergency service numbers and some common numbers set in advance, when the calling party dials the numbers, the position sharing method provided by the embodiment of the disclosure can be applied to write the position information in the call setup message and send the position information along with the call setup message.

For example, the emergency call number may be 112, 911, etc., and the wireless network and the user equipment can support identification of emergency call numbers in different countries and regions, for example, the emergency call numbers currently used in continental china may include: 112 (note: emergency services such as 110, 119, and 120 are used as ordinary telephone services in our country). It should be noted that, in the case that the user equipment is provided with or not provided with the SIM card, the user may dial an emergency call through the user equipment, so as to establish an emergency call connection with the PSAP.

In a possible implementation, the location information of the calling party user equipment 10 may further include a plurality of historical location information of the calling party user equipment 14, the historical location information being used to represent a historical location trajectory of the calling party user equipment 10.

In one example, the number of historical location information may be set according to the device capabilities of the calling party user device, and the disclosure is not limited thereto.

In one example, each historical location information may be separated by a preset time, for example, each historical location information may be separated by 30 minutes.

Through the method, the embodiment of the disclosure can report the current position information of the calling party user equipment, and can also report a plurality of historical position information.

It should be noted that, in the call setup message, the location information or other information may have a plurality of coding modes, for example, a short message coding mode, a 7-bits coding mode, a binary coding mode, and the like, and as for the coding mode of the location information, the embodiment of the present disclosure is not limited.

In some scenarios, the disclosed embodiments may also require the called party user equipment 14 to provide location information, e.g., in one possible implementation, the call setup message may also include location request indication information, which is used to request location information of the called party user equipment 14.

In one example, the call setup message may be set to include an indication field of location request indication information, which may include, for example, 2 bits, where a first bit may be used to indicate whether the called party user is required to provide location information and a second bit may be used to indicate whether the calling party user equipment provides location information. Of course, the first bit may be set to indicate whether the calling party user equipment provides location information, and the second bit may be set to indicate whether the called party user equipment is required to provide location information, as will be further described below.

In one example, the first bit may be set to 1 to indicate that the called party user equipment 14 is required to provide address information and the first bit may be set to 0 to indicate that the called party user equipment 14 is not required to provide address information. When the called user equipment 14 receives the location request indication information and the first bit in the location request indication information is 1, the called user equipment 14 obtains the location information according to the indication and sends the location information to the calling user equipment 10.

In one example, a second bit may be set to 1 to indicate that the calling party user equipment 10 has transmitted location information and a second bit may be set to 0 to indicate that the calling party user equipment 10 has not transmitted location information. When the called user equipment 14 receives the location request indication information and the second bit in the location request indication information is 1, it indicates that the calling user equipment 10 has sent the location information, and the called user equipment 14 may obtain the location information of the calling user equipment in the call setup message.

In one possible implementation, as shown in fig. 3, after outputting the call setup message at step S11, the method may further include:

step S15, receiving a specified prompting message, where the specified prompting message may include location information of the called user equipment 14;

the specified prompting message may include any one or more of an ALERTING message (ALERTING), a connection message (CONNECT), a cancel connection message (DISCONNECT), a connection RELEASE message (RELEASE), a connection RELEASE COMPLETE message (RELEASE COMPLETE), and a connection PROGRESS message (PROGRESS), where the ALERTING message is used to indicate that an ALERTING service has been started, the connection message is used to indicate that the called user equipment 14 accepts the call, the cancel connection message is used to indicate that the connection with the called user equipment 14 is disconnected, the connection RELEASE message is used to indicate that the connection with the called user equipment 14 is released, the connection RELEASE COMPLETE message is used to indicate that the connection with the called user equipment 14 is released, and the PROGRESS message is used to indicate the PROGRESS of the call.

When the called party user equipment receives the location request indication information and the location request indication information indicates that the called party user equipment 14 provides location information, the called party user equipment 14 obtains the location information according to the indication and sends the location information to the calling party user equipment 10 by formulating a prompt message.

Through the above method, the embodiment of the present disclosure may receive address information of the called party user equipment 14.

The above method can be applied in a variety of scenarios, for example, when a parent calls a child, the child may be required to provide its location information, so that the safety of the child can be ensured; for example, when an upper level calls a lower level, the lower level may be required to provide its location information and the like.

Of course, such a correspondence relationship may be set in advance, for example, number 1 is set as a parent, number 2 is set as a child; number 3 is set as upper level, a plurality of numbers are set as lower level, and so on.

In a possible implementation, before outputting the call setup message at step S11, the method may further include:

acquiring preset information corresponding to a called number of the called user equipment 14 according to a preset corresponding relationship, wherein the preset corresponding relationship comprises a corresponding relationship between the called number and the preset information;

and adding the preset information into the call establishment message.

The embodiment of the disclosure can write other information in the call establishment message and provide rich information reporting.

In an example, the preset information may include preset state description information, where the preset state description information may be edited in advance, corresponding preset state description information may be edited in advance for different called numbers, and for preset state description information corresponding to different called numbers, specific content is not limited in the embodiments of the present disclosure.

In one example, some information may also be edited as preset information added to the call setup message when a call is placed, for example, information indicating the present state (emergency state, etc.), the reason for placing the call, and the like.

It should be noted that, in the call flow, the calling user equipment 10 establishes a connection with the called user equipment 14 through the network element equipment 12, the embodiment of the present disclosure takes the calling user equipment 10 and the called user equipment 14 as two ends for exemplary description, and it should be understood that, in each embodiment of the present disclosure, the communication between the calling user equipment 10 and the called user equipment 14 is centered on the network element equipment 12, that is, the network element equipment 12 serves as an intermediate equipment to forward information of the calling user equipment 10 and the called user equipment 14, and control the communication flow of the calling user equipment 10 and the called user equipment 14.

The following is an exemplary description of the various call flows.

Referring to table 1, table 1 shows an illustration of a GSM emergency call flow.

TABLE 1

Wherein, MS denotes user equipment and SS denotes network element equipment. It should be noted that, part of the contents of the GSM emergency call flow are described above, and the specific information of the GSM emergency call flow refers to the relevant communication protocol of the GSM emergency call flow, which is not described herein again. In addition, the normal call flow of the GSM is not described in detail in the disclosure, and the emergency call flow of the GSM is similar to the emergency call flow.

As shown in table 1, if the address information of the calling user equipment needs to be obtained, the related art generally initiates a positioning procedure for the calling user equipment 10 in step 8, the network element device 12 sends out RR application information to control the calling user equipment 10 to report the location information, and in step 9, the user equipment reports the RR application information to report the location information.

The embodiment of the present disclosure may send the location information by using the call setup message when the emergency call is setup in the seventh step, so as to report the location information of the calling party ue 10, and thus, compared with the related art, the present disclosure not only reduces the interaction time and the call response time, but also realizes the active reporting of the location information of the ue in the location information reporting, and when the emergency call is setup, the location information is reported in advance by using the call setup message, so as to reduce the call response time, and improve the user experience.

When the network receives the call setup message, it may forward it to the called party user equipment 14 so that the called party user equipment 14 may quickly obtain the location information of the calling party user equipment 10 to quickly locate it.

Referring to table 2, table 2 shows an illustration of a WCDMA emergency call flow.

TABLE 2

Wherein, UE represents user equipment, and SS represents network element equipment. It should be noted that, the above introduces part of the content of the WCDMA emergency call flow, and the detailed introduction of the WCDMA emergency call flow refers to the relevant communication protocol of the WCDMA emergency call flow, and the disclosure does not describe the normal call flow of WCDMA, and the normal call flow of WCDMA is similar to the emergency call flow.

As shown in table 2, in the related art, if the address information of the calling user equipment 10 needs to be acquired, the related art generally initiates a positioning procedure for the calling user equipment 10 at step 14, the network element device 12 sends a measurement control message to control the calling user equipment 10 to report the location information, and at step 15, the user equipment sends a measurement report message to report the location information.

For WCDMA, the embodiment of the present disclosure may complete the reporting of the location information in step 7, and may greatly shorten the time for the network element device or the called user device 14 to obtain the calling user device 10.

The above describes an exemplary call flow by using GSM and WCDMA as examples, the above describes a manner of obtaining the location information of the user equipment based on the control plane, and the following describes an exemplary flow of obtaining the location information of the user equipment based on the user plane.

The process of obtaining address information based on the user plane comprises the following steps:

1. if an emergency call from a SET (representing user equipment) needs to be established. Note that this step is not within the scope of SUPL (Secure User plane location) and SUPL testing, but may be necessary.

2. An NI (Network Initiated) emergency services location session is Initiated.

It should be noted that, after receiving the call setup message, the network element device 12 may also obtain the location information in the call setup message, and may process and change the call setup message according to a protocol, or generate a new call setup message according to the call setup message of the calling party user equipment 10 and send the new call setup message to the called party user equipment 14, which is not limited in this disclosure.

In one possible embodiment, location request indication information may be included in the call setup message to indicate whether location information for calling party user equipment 10 is included in the call setup message and whether called party user equipment 14 is instructed to transmit the location information.

In one possible embodiment, the method may further include:

in case the location request indication information in the call setup message indicates that location information of the called party user equipment 14 is provided, sending the location information of the called party user equipment.

The location information of the called party user equipment 14 may be stored in a preset storage space, and the called party user equipment 14 of the embodiment of the present disclosure may obtain the location information from the preset storage space in which the location information is specially stored, or may obtain the location information from storage spaces of other application programs, which is not limited in the present disclosure.

In one possible implementation, the sending the location information of the called party user equipment 14 may include:

The method and the device for sending the position information of the called party user equipment can send the position information of the called party user equipment through the appointed indication message, and therefore the method and the device for sending the position information of the called party user equipment can feed back the position information of the called party user equipment and adapt to the current protocol.

It should be noted that the above-mentioned location sharing method of the called user equipment 14 corresponds to the location sharing method of the calling user equipment 10, and for specific introduction, reference is made to the description of the location sharing method of the calling user equipment 10, which is not described herein again.

In addition, for a specific description of formulating the indication message, please refer to the related communication protocol, which is not described herein again.

As can be seen from the above description, the location sharing method provided in the present disclosure, regardless of whether the MO CALL (Mobile originating CALL) or the MT CALL (Mobile Terminated CALL), may actively provide location information to the other party, or may require the other party to provide location information, and by reporting the location information to the network in the CALL SETUP message (EMERGENCY SETUP or SETUP), the time node of reporting the location information may be advanced, thereby improving response time.

Taking the calling as an example, after receiving the SETUP/EMERGENCY SETUP, the network element device integrates the information such as < "emergency directory >," emergency information container "/" calling location information container ", and" second location information providing unit ", and realizes the transmission of location information with the user equipment.

In order to implement the above method, the existing communication protocol needs to be modified, and some possible modifications are introduced below, so that the modified communication protocol can implement the above method.

In one example, the modification to the call setup message (emergency setup message) in the call setup procedures of table 1, table 2, etc. may include:

the first location Information providing unit IEI (Information Element Identifier) and the second location Information providing unit IEI are respectively marked as XX and YY, and the allowed value may be a legal value that is not used in the protocol 3GPP TS24.008 Annex K. The first position information providing unit defines the position information by the current equipment and specially expresses the position information, such as characters, labels and the like; the second position information provides a standard representation of the position and its measurement migrated from an existing standard and adds this extension to the history track. Of course, the above modification is exemplary, and in other modifications, the first position information providing unit and the second position information providing unit may be combined into one. The disclosed embodiments are described in a separate manner.

In an example, the first location information providing unit may include a plurality of information, for example, may include location information, preset information, location request indication information, and the like, and the encoding manner of each information may include a plurality of information, for example, may include a 7-bits encoding manner, an 8-bits encoding manner, a short message encoding manner, a binary encoding manner, and the like, and the disclosure is not limited thereto.

Please refer to fig. 5a, fig. 5b, fig. 5c, fig. 5d, fig. 5e, fig. 5f, and fig. 5g, and fig. 5a, fig. 5b, fig. 5c, fig. 5d, fig. 5e, fig. 5f, and fig. 5g illustrate possible schematic diagrams of the first position information providing unit.

In one example, as shown in fig. 5a, the first position information providing unit may include a plurality of bytes, for example, bytes 1 to n, where n > 4 and is an integer; in one example, as shown in fig. 5a, the first location information providing unit may comprise a plurality of information fields, for example may comprise a user location information container IEI, wherein the user location information container IEI may occupy 1 byte; a length indication of the user location information container may also be included, wherein the length indication of the user location information container may occupy 2 bytes; user location information content may also be included, where the user location information content may occupy a plurality of bytes, for example, from byte occupied 4 to byte occupied n. :

in one example, as shown in FIG. 5b, the user location information content may include multiple items, i.e., multiple types of information may be included in the user location information content. For example, the item 1 may include bytes 4 to 8 (byte × 2), the item 2 may include bytes 9 (byte × 2+1) to 12 (byte × 3), and the like, and the length of each item may also be set to be other, which is not limited in the embodiment of the present disclosure.

In one example, as shown in fig. 5c, each user location information content item may include multiple information fields (e.g., user location information content item type, user location information content item length, user location information content value), which is illustrated by example item 1, the user location information content type may occupy 1 byte (byte 4), the user location information content item length may occupy 1 byte (byte 5) and the user location information content item value may occupy the remaining bytes (bytes 6-bytes × 2) of the item.

An exemplary description of the user location information content item will be given below.

As shown in fig. 5d, the user location information content item may include multiple types (multiple types of items), for example, item 1 (type 1) may be used to indicate whether the message is actively provided or passively provided, whether the other party is required to provide location information, whether the confirmation of the location information is performed, or the like (i.e., location request indication information); item 2 may be used to represent location information for the current location, for example, it may be a textual geographic traffic location (e.g., "Shanghai XXX road XXX and XXX number XXX room"), although it may be in other forms such as latitude and longitude; item 3 may be used to represent predefined emergency information or edit information, etc. (i.e., the aforementioned preset information). Of course, the above description is exemplary, and in other embodiments, other item types may be included (for example, other information such as machine auto-id information may also be included) to provide rich information reporting.

The setting of the position request indication information is exemplarily explained below.

As shown in fig. 5e, the location request indication information may include 3 bytes, where byte 1 is used to indicate the user location information content item type (i.e. location request indication information), byte 2 is used to indicate the length of the location request indication information, and byte 3 is used to indicate whether the user equipment actively provides location information (1 st byte) and whether the other party is required to provide location information (2 nd byte).

In one example, as shown in fig. 5f, a 1 st bit of byte 3 may be set to indicate whether to actively provide location information, wherein a first bit of 0 may be set to indicate that location information is not actively provided and a first bit of 1 may be set to indicate that location information is actively provided.

In one example, as shown in fig. 5f, a 2 nd bit of byte 3 may be set for indicating whether the other party is required to provide the location information, wherein the 2 nd bit may be set to 0 to indicate that the other party is not required to provide the location information, and the 2 nd bit is set to 1 to indicate that the other party is required to provide the location information. Other bits of byte 3 may be reserved bits to carry other information, that is, the location request indication information in the embodiment of the present disclosure may include others, which is not limited in the present disclosure.

The format of the location information is exemplarily described below.

As shown in fig. 5g, the location information may include a plurality of information fields, each of which may include at least one byte, wherein the information field of the location information may include an indication field of a location information type for indicating that the field represents the location information, a length field (which may include 1 byte) of the location information, an encoding format indication field of the location information, which may include 1 byte, for indicating an encoding format of the content of the location information; and a location information content field for carrying the specific content of the location information (such as geographic traffic location).

For convenience of reading and understanding, the encoding format of the location information may be set to be a short message encoding format, and of course, the encoding format of the location information may include multiple types, which is not limited in this disclosure, and a person skilled in the art may refer to the related technology or protocol setting, for example, refer to 3GPP TS 23.038.

The first position information providing unit is exemplarily described above, and the second position information providing unit is exemplarily described below.

Referring to fig. 6, fig. 6 is a schematic diagram illustrating a second position information providing unit according to an embodiment of the present disclosure.

In one example, as shown in fig. 6, the second location information providing unit may include a second location information providing unit IEI (byte 1), a length of the content of the second location information providing unit (byte 2), and a location information content (bytes) provided by the second location information providing unit.

In one example, the "location information content" can be encoded using asn.1 coding, including but not limited to currently available positioning technologies, and can continue to expand. It is also important to be able to obtain historical tracks in the case of emergency calls. The following is by way of example only and reference is made to 3GPP TS 36.355.

The number of the historical position information reported by the user equipment can be set according to the capability of the user equipment (for example, the number is set to 24 in the previous example), and the historical position information can be arranged according to the sequence of the previous position and the next position, so that the motion track can be conveniently and quickly obtained, and further the track prejudgment can be made within a certain time range.

Of course, the present disclosure does not limit the specific manner how to set the number of the historical location information reported by the ue, and those skilled in the art can implement the setting with reference to the related art.

Table 14 gives a possible example in order to make the existing protocol support the location sharing method proposed in the embodiment of the present disclosure, and a location information message needs to be added.

Table 14 shows a possible illustration of a newly added user location information message.

TABLE 14

Through the modification of the protocol, the embodiment of the present disclosure may report the location information of the ue when sending the call setup message, and the reported information may also include other various information, so as to reduce message interaction and facilitate faster response, and meanwhile, may report rich information (such as address described in text, reason, various IDs convenient for identification, absolute location, relative location, measurement data, etc.), and the source of the reported information may be a mobile terminal system, an application, a predefinition, a user input, etc. This information greatly reduces the time to communicate during the call). In addition, the embodiment of the disclosure reports the location information when the call setup message is sent, and compared with the related art, the reporting time of the location information can be made to be consistent so as to facilitate management.

The disclosed embodiment can be used with the existing scheme, and has no problems of exclusivity and compatibility; compared with the prior scheme, the situation that the positioning information data codes are different under different communication modes does not exist; more positioning information can be conveniently added in the future, and the method has better expansibility; one party in the call can not only actively provide the position, but also require the other party to provide the position, and the function is complete; it is convenient to implement part or all of the components according to actual conditions. For example, only the longitude and latitude information is reported, and only 20 bytes are added. If the device moves within a certain scene, only one ID may be required.
