Description

Emergency call method and terminal equipment

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to an emergency call method and a terminal device.

Background

Emergency telephone numbers are set in all countries of the world and can make emergency calls under special conditions, for example, the emergency telephone numbers can be alarm telephones, emergency telephones, fire alarm telephones and the like. In order to ensure the communication of the emergency call as much as possible, the communication system determines the approximate position by a Subscriber Identity Module (SIM) card in the terminal equipment, and then receives the nearest service desk.

After the user makes an emergency call, the help seeker usually tells the rescuer the specific position of the help seeker by dictation, and under the condition, if the rescuer is unfamiliar with the position of the help seeker, the help seeker cannot be helped in time. Or, the position of the help seeker may change while the help seeker is moving, which may cause the rescuer to be unable to determine the position of the help seeker and also unable to provide help to the help seeker in time. The help seeker may transmit the position information of the help seeker to the rescuer through the data network, but when the terminal device used by the help seeker is in a defaulting shutdown state, the position information cannot be notified to the rescuer, and the help seeker cannot be provided with help in time.

It is obvious that emergency call can not guarantee that the rescuer accurately knows the position of the help seeker in time at present, can not provide help for the help seeker in time.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly and completely understood, the technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

At present, a party (help seeker) calling an emergency transmits position information of the party to a rescuer through a data network, for example, the position information is informed to the help seeker through a voice mode, but when a terminal device used by the help seeker is in a defaulting shutdown state, the position information cannot be informed to the rescuer, and the help seeker cannot be provided with help in time. It is obvious that emergency call can not guarantee that the rescuer accurately knows the position of the help seeker in time at present, can not provide help for the help seeker in time.

In view of this, the embodiment of the present invention provides an emergency call method, in which after an emergency call is successful, a terminal device may send its own location information to a service desk through a signaling transmission manner without transmitting the location information through a data network, so that even if the terminal device is in a defaulting shutdown state, the location information can be transmitted, so as to ensure that a rescuer timely and accurately knows the location of a help seeker as much as possible, and provide help for the help seeker.

The technical scheme provided by the embodiment of the invention is described in the following with the accompanying drawings of the specification.

Referring to fig. 1, an embodiment of the present invention provides an emergency call method, which may be executed by a terminal device, such as a mobile phone, and a specific flow of the emergency call method is described as follows.

And S101, calling at least once by adopting the emergency telephone number.

The emergency call number may be classified into various types in terms of use, such as an emergency telephone number for performing alarm call for help, an emergency telephone number for performing fire call for help, an emergency telephone number for performing medical assistance, and the like. When the user needs help, at least one call can be made by dialing the emergency telephone number to obtain help. The communication system determines the approximate location via the SIM card in the terminal device and then connects to the nearest manual service desk.

S102, when the call is successful, the position information of the user is acquired.

Often, the rescuer needs to inform the rescuer where he or she is in order for the rescuer to provide even assistance to the rescuer. In the prior art, a help seeker tells a rescuer the specific position of the help seeker through dictation, and under the condition, if the rescuer is not familiar with the position of the help seeker, the help seeker cannot be helped in time. Or, the position of the help seeker may change while the help seeker is moving, which may cause the rescuer to be unable to determine the position of the help seeker and also unable to provide help to the help seeker in time. The help seeker may transmit the position information of the help seeker to the rescuer through the data network, but when the terminal device used by the help seeker is in a defaulting shutdown state, the position information cannot be notified to the rescuer, and the help seeker cannot be provided with help in time.

Therefore, in the embodiment of the present invention, after determining that the call is successful, the terminal device may obtain the location information of the terminal device through a Global Positioning System (GPS) module built in the terminal device, which is more accurate.

In a possible implementation manner, the terminal device may periodically acquire the position information of itself, so as to ensure that the position of the help seeker can be determined more accurately even if the help seeker is moving.

S103, the position information is sent to a service desk through a signaling link, wherein the signaling link is a channel for transmitting data by adopting signaling.

After the terminal equipment acquires the position information of the terminal equipment, the acquired position information can be sent to the service desk through the signaling link, wherein the signaling link is a channel for transmitting data through signaling, so that the transmission is not needed through a data network, and the transmission of the position information can be realized even if the terminal equipment is in arrearage shutdown, so that the rescuer can be guaranteed to timely and accurately know the position of the help seeker as far as possible, and help is provided for the help seeker.

In the embodiment of the invention, the terminal equipment can adopt No. 7 signaling to send the position information to the service desk through the signaling link. The terminal device can send the signaling No. 7 carrying the position information to the service desk, and the service desk analyzes the signaling No. 7, so as to obtain the position information of the terminal device.

Specifically, the terminal device may encapsulate the location information in the No. 7 signaling according to a preset format of the No. 7 signaling, and send the No. 7 signaling carrying the location information to the service desk through the signaling link. When the position information is encapsulated in the No. 7 signaling according to the preset No. 7 signaling format, filling a service type field of a Message Signaling Unit (MSU) according to the position information, wherein the service type field is used for indicating the position information of the calling party, converting the position information into a first character string according to a predefined communication protocol, and filling the first character string in the signaling information field of the No. 7 signaling.

For convenience of understanding, the technical solutions provided by the embodiments of the present invention are described below with specific examples.

When the terminal equipment dials an emergency call to carry out voice help seeking, the terminal equipment acquires the position information of the terminal equipment through the GPS module and sends the position information to the public information service desk through the No. 7 signaling system. In the continuous process of the call, the terminal equipment can acquire the position information once every other time interval (such as 3 seconds) and send the position information through the MSU of the signaling system, so that the position information of the help seeker is accurately sent to the public information service desk in real time. And the public information service desk processes the current position information of the help seeker possibly contained in the MSU while processing the emergency call content. After the public information service desk receives the position information, the position of the help seeker can be located through the electronic map, and therefore the position of the help seeker is obtained.

The following introduces definitions for MSU:

referring to table 1, the format of the MSU is illustrated. The embodiment of the invention can customize a Signaling Information Field (SIF) Field and a Service Information Field (SIO) in the table 1.

TABLE 1

Specifically, the SIO may be redefined into two sub-segments: the service sub-segment SI and the service sub-segment SSF have 8 bytes, wherein the SI and the SSF each occupy 4 bits, as shown in table 2, and table 2 indicates 4 bits by DCBA.

TABLE 2

SSF	SI
		DCBA	DCBA

The four bit DCBA definition of the service sub-segment SI is as in table 3 (this definition is the original definition of signaling No. 7):

TABLE 3

Serial number	Service sub-segment SI	Description of the invention
			1	0000	Signaling network management messages (level 3 messages)
2	0001	Signaling network test and maintenance messages (level 3 messages)
			3	0010	For standby
4	0011	SCCP signaling circuit control part
			5	0100	TUP telephone subscriber part
6	0101	ISUP ISDN user part
			7	0110	DUP (Call and circuit related message)
8	0111	Performance registration and revocation
				The rest(s)	For standby

As can be seen from table 3, in the MSU signaling information in signaling No. 7, 16 types of information are available, and currently, 7 types of information are already used, and 9 types of information are also available. Therefore, 1001 in the embodiment of the present invention may be used as the location information of the terminal device, and after the update, the four-bit DCBA definition of the service sub-segment SI is as shown in table 4:

TABLE 4

The four bits DCBA for the traffic sub-segment SSF are defined as follows:

only two bits DC in SSF are currently defined and two bits BA are not defined, as in table 5:

TABLE 5

Serial number	Service subsegment SSF high two-bit DC	Description of the invention
			1	00	International network
2	01	International standby
			3	10	Domestic network
4	11	Domestic standby

In the embodiment of the invention, two bits of DC can be 10 (domestic network), and two bits of BA can be 00.

In summary, the format of SIO (8 bits) definition in the embodiment of the present invention is shown in table 6:

TABLE 6

	SSF	SI
			Bit position	DCBA	DCBA
Value taking	1000	1001

The 8 bits of the above SIO indicate: caller location information for the home network.

Redefinition for SIF: SIF consists of 3 parts: a route tag part, a message type part and a signaling information part. All MSU routing tag portions have the same format, while the format of the message type portion and the signaling message portion is determined by the SI in the SIO.

The format of SIF is shown in table 7:

TABLE 7

Signalling messages

Message type

SLS

OPC

DPC

DPC, OPC, and SLS in table 7 are the contents of the routing label, respectively, and all MSUs have the same format, and have 56 bits, with DPC occupying 24 bits, OPC24 occupying 8 bits, and SLS occupying 8 bits.

In this embodiment of the present invention, the customized message type and the signaling message are integrated and collectively represent location information of the terminal device, for example, the terminal device may convert the location information into a first character string, which may be SGPGGA, 161229,487, 3723,2475, N, 12158,3416, W, 1,07,1,0,9,0, M, 0000, 18. The information is separated by commas, and has 17 fields in total, and the carriage return field and the line feed field are not included. The detailed analysis is shown in table 8:

In the implementation of the present invention, the terminal device may convert the location information into a string, for example, SGPGGA, 161229,487, 3723,2475, N, 12158,3416, W, 1,07,1,0,9,0, M,, 0000 × 18, and the message type and the signaling message field in SIF placed in the MSU message signaling unit, and the routing identifier field of the MSU is not changed, for example, as shown in table 9:

TABLE 9

Location information

SLS

OPC

DPC

The embodiment of the invention simultaneously sets the SIO field of the MSU to 10001001, and after the two information are filled, the MSU signaling is sent to the public information service desk through the No. 7 signaling network, so that the public service desk can track the position change condition of a help seeker.

The public information service desk receives the MSU message signaling unit from the signaling network, analyzes the value of SIO, and processes according to the original standard process if SIO is not 10001001; if the MSU is 10001001, the MSU is the position information of the help seeker, the SIF field of the MSU is read to obtain the position information of the help seeker, and the position information is displayed in front of the public service desk personnel through the electronic map.

After the call is over, the help seeker presses the hang-up key, the terminal equipment sends a hang-up signal through the signaling network, and the public information service desk receives the signaling requiring the hang-up and is responsible for completing the analysis of the data network through the signaling network. Therefore, as long as the call of the terminal equipment is not disconnected, the terminal equipment of the help seeker can send the position information of the help seeker to the public information service desk in real time, so that the public information service desk can know the circuit diagram of the position change of the help seeker, and the help seeker can be conveniently found.

In summary, in the embodiment of the present invention, after the emergency call is successful, the terminal device may send the location information of the terminal device to the service desk through a signaling transmission method, and does not need to transmit the location information through a data network, so that even if the terminal device is in a defaulting shutdown state, the transmission of the location information may be implemented, so as to ensure that the rescuer timely and accurately knows the location of the help seeker as much as possible, and provide help for the help seeker.

The embodiment of the invention transmits the position information through the No. 7 signaling network and does not transmit through the data network, so that a public service center does not need to externally publish data interface information and maintain the data interface information in terminal equipment, the system is simpler, and the dependence on an external network is reduced.

The embodiment of the invention has no special requirement on the telephone state of the terminal equipment, and can transmit the position information through the signaling network as long as the emergency call can be dialed, and the position information can be transmitted through the signaling network even for the defaulting shutdown user. There is no requirement for the network of the operator, and the location information can be transmitted through signaling as long as the call can be made. At present, in a data network mode, except for an LTE network, data transmission cannot be performed while a call is made.
