In the specification of the third Generation Partnership Project (3 GPP), some flows for sending user location information during a call are defined, and table 1 shows an implementation manner for obtaining a location of a Mobile Station (MS) through network triggering in a Global System for Mobile Communications (GSM) emergency call flow, where an SS in the table is a network simulator (SS).

TABLE 1 GSM Emergency Call flow

As shown in steps 8 and 9 in table 1, it can be seen from the table that if a situation with poor network signal quality is encountered, the network may not be allocated immediately, i.e. step 3 may fail, then the subsequent step 7, i.e. the process of establishing the emergency call, may not be implemented, and at this time step 8 and step 9, i.e. the location of the MS cannot be sent or stored, which is inconvenient for providing effective clues for subsequent rescue or accident investigation.

In order to solve the above problem, this embodiment discloses an application example of a location saving method based on an emergency call, and in the application example of the present disclosure, in order to effectively save a location of an emergency call, an emergency call geographic location basic file (EF) may be created in a storage device of a User Equipment (UE), such as a Universal Subscriber Identity Module (USIM) or a non-volatile Random Access Memory (NV)_ECGLI，ElementaryFile_{Emergency Call Geographical Location Information}) For storing the current location information during the emergency call and updating the EF each time the emergency call is established_ECGLIThe method of (1).

It can be seen from the foregoing disclosure that the location saving method based on emergency call provided by the present disclosure is applied to a storage device inside a UE, and therefore, the received update instruction may come from the UE, that is, in a possible implementation manner, the UE acquires current location information when the emergency call request is established, and generates an update instruction according to the current location information.

In a possible implementation manner, the current location information may be related information indicating a current location of the UE, and the specific information content of the current location information may be flexibly determined according to an actual situation, such as a current coordinate of the UE in a world coordinate system, a current longitude or latitude of the UE, and the like, which is not limited herein. Likewise, the manner in which the UE acquires the current location information is not limited, and in a possible implementation manner, the UE may acquire the current location information through an internal positioning component, such as a GPS, a gyroscope, or the like.

After the UE acquires the current location information, it may generate an update instruction according to the current location information, and the specific content of the update instruction is not limited in the embodiment of the present disclosure, since the main purpose of the update instruction is to instruct a USIM or a storage device such as an NV to update the emergency call geographic location basic file EF_ECGLIThus, in one possible implementation, it may contain indication information and current location information, the indication information may be used to indicate that the storage device performs the updating action, and the current location information may be used to indicate that the storage device should specifically update the information content.

After the UE generates the update command, the UE may transmit the update command to an internal storage device, and after the storage device receives the update command in step S11, the storage device may update the EF according to the update command in step S12_ECGLI。

Specifically, at EF_ECGLIWhen recording the information of the emergency call request, the specific form of the information can be flexibly selected according to the actual situation, and is not limited to the following disclosed embodiments. It has been proposed in the above-disclosed embodiment that EF_ECGLIMay include emergency call request time information and emergency call request location information. In a possible implementation manner, the form of the emergency call request time information may be a date and a specific time when the emergency call request is established, specifically, whether the date is before or the specific time is before, or whether the specific time is accurate to minutes or seconds, and the like, which may be flexibly selected according to the actual situation, and is not limited in the embodiment of the present disclosure.

The emergency call request location information may be in different coding forms according to the specific content of the information. In one possible implementation, the emergency call request location information may be encoded in a global geographic area description, GAD, format or in a NMEA protocol format.
