Each BS270 may serve one or more sectors (or regions), each sector covered by a multi-directional antenna or an antenna pointing in a particular direction being radially distant from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS270 may be configured to support multiple frequency allocations, with each frequency allocation having a particular frequency spectrum (e.g., 1.25MHz,5MHz, etc.).

The intersection of partitions with frequency allocations may be referred to as a CDMA channel. The BS270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to generically refer to a single BSC275 and at least one BS 270. The base stations may also be referred to as "cells". Alternatively, each sector of a particular BS270 may be referred to as a plurality of cell sites.

Based on the above mobile terminal hardware structure and communication system, various embodiments of the present invention are proposed.

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

First embodiment

A first embodiment of the present invention provides an emergency call method, which may be applied to a mobile terminal having an emergency call function.

Here, the above-mentioned mobile terminal may be a mobile terminal having a display screen, and the above-mentioned mobile terminal includes, but is not limited to, a mobile phone, a notebook computer, a camera, a PDA, a PAD, a PMP, a navigation device, and the like. The terminal can be connected to the internet, wherein the connection mode can be through a mobile internet network provided by an operator, and can also be through accessing a wireless access point to perform network connection.

Here, if the mobile terminal has an operating system, the operating system may be UNIX, L inux, Windows, Android (Android), Windows Phone, or the like.

It should be noted that the type, shape, size, and the like of the display screen on the mobile terminal are not limited, and the display screen on the mobile terminal may be a liquid crystal display screen, for example.

In the first embodiment of the present invention, the display screen is used to provide a man-machine interface for a user, where the mobile terminal may store a plurality of emergency phone numbers in advance, and when it is necessary to specify the emergency phone number, the emergency phone number may be a phone number that can be successfully called without using a Subscriber Identity Module (SIM) card, and the emergency phone number may not be stored in the SIM card.

Fig. 3 is a flowchart of a first embodiment of the emergency call method of the present invention, as shown in fig. 3, the flowchart includes:

step 301: an emergency telephone number to be used when making an emergency call is determined.

It is to be understood that the emergency telephone number may be divided into various types in terms of usage, 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.

The same type of emergency telephone number used in various parts of the world is different, for example, for an emergency telephone number using medical assistance, the emergency telephone number used at site 1 is a1, and the emergency telephone number used at site 2 is a 2; thus, if the mobile terminal needs to make a call using an emergency phone number, it is necessary to determine the emergency phone number at which the current location can make a call.

Optionally, the above-mentioned determining an emergency phone number to be used when making an emergency call may include:

step 3011: and acquiring the current geographical position information of the mobile terminal.

In actual implementation, the mobile terminal may determine the current location information of the mobile terminal by using the location information module, for example, the mobile terminal may obtain the current location information of the mobile terminal by using positioning technologies such as satellite positioning, base station positioning, wifi positioning, and the like.

Here, the current location information acquired by the mobile terminal may be stored in the form of latitude and longitude.

Step 3012: obtaining at least one emergency telephone number corresponding to the current geographical position information of the mobile terminal according to the preset corresponding relation between the geographical position information and the emergency telephone number;

because the same type of emergency telephone numbers adopted by various regions may be different, a plurality of non-overlapping geographical regions can be divided in advance, and various types of emergency telephone numbers corresponding to each geographical region are set; for example, the divided geographic regions include: zone 1, zone 2, and zone 3, the first type of emergency telephone number corresponding to zone 1 may be B1, and the second type of emergency telephone number corresponding to zone 1 may be C1; the first type of emergency phone number corresponding to area 2 may be B2, and the second type of emergency phone number corresponding to area 2 may be C2; the first type of emergency phone number corresponding to zone 3 may be B3, and the second type of emergency phone number corresponding to zone 1 may be C3; here, the first type of emergency phone number may be an emergency phone number for performing alarm for help, and the second type of emergency phone number may be an emergency phone number for performing medical assistance.

Thus, after the current position of the mobile terminal is obtained, the geographical area where the current position of the mobile terminal is located is determined, and then the corresponding emergency telephone number is determined according to the geographical area where the current position of the mobile terminal is located; for example, when the geographic area where the current location of the mobile terminal is located is area 2, the emergency phone number corresponding to the current geographic location information of the mobile terminal may be B2 or C2, and it is specifically determined by the user according to the actual situation, which emergency phone number is used.

Step 3013: and determining the emergency telephone number which needs to be adopted when the emergency call is made in the obtained at least one emergency telephone number.

After obtaining at least one emergency telephone number, the emergency telephone number to be used for making an emergency call may be determined according to practical application requirements.

In an optional embodiment of this step, when the user dials a call, the mobile terminal determines whether the telephone number currently dialed by the user is an emergency telephone number, and if the telephone number currently dialed by the user is not the emergency telephone number, the call is made according to a normal call flow;

if the current phone number dialed by the user is an emergency phone number, further judging whether the current phone number dialed by the user belongs to the emergency phone number corresponding to the current geographical location information of the mobile terminal (namely, at least one obtained emergency phone number), if so, executing step 302, and directly calling by adopting the corresponding emergency phone number; if the current geographical location information of the mobile terminal does not belong to the emergency telephone number, displaying the emergency telephone number corresponding to the current geographical location information of the mobile terminal to the user, and prompting the user to select one emergency telephone number from the emergency telephone numbers corresponding to the current geographical location information of the mobile terminal; fig. 4 shows an example of prompting the user to select an emergency phone number, and as shown in fig. 4, the emergency phone numbers corresponding to the current geographical location information of the mobile terminal displayed on the user interface include "110", "120", and "119", and the mobile terminal displays "please select an emergency phone number" on the user interface, at this time, the user selects according to the actual application requirements.

In another alternative embodiment of this step, the derived at least one emergency telephone number may be stored in the mobile terminal for easy lookup by the user; when a user needs to dial an emergency telephone number, the emergency telephone number corresponding to the current geographical position can be searched in the mobile terminal, and then one of the searched emergency telephone numbers can be selected for calling.

Step 302: calling at least once by adopting an emergency telephone number in a first channel;

step 303: when the first channel adopts the emergency telephone number to carry out continuous N times of calls, the second channel adopts the emergency telephone number to carry out at least one call, wherein N is more than 1;

here, when the first channel is an emergency channel, the second channel is a normal telephone channel; when the first channel is a common telephone channel, the second channel is an emergency channel.

Preferably, the priority of the emergency channel and the priority of the common telephone channel can be preset;

In practical implementation, when the priorities of the emergency channel and the common telephone channel are set, the priorities of the emergency channel and the common telephone channel can be represented by numerical values, and the lower the numerical value is, the higher the priority is; when setting the priority of the emergency channel and the normal telephone channel, the priority order between the two channels may also be set, fig. 5 shows a schematic diagram of setting the priority of the emergency channel and the normal telephone channel, and as shown in fig. 5, "please select the channel with higher priority" is displayed on the user interface of the mobile terminal, so that the user may select the emergency channel as the channel with higher priority, or select the normal telephone channel as the channel with higher priority.

By applying the emergency call method of the first embodiment of the present invention, the emergency phone number to be used when an emergency call is made can be determined first; then, at least one call is made by adopting an emergency telephone number in a first channel; when the first channel does not successfully call for N times continuously by adopting the emergency telephone number, the second channel calls for at least one time by adopting the emergency telephone number; therefore, when the call of the emergency telephone number adopted by the first channel fails, the emergency telephone number can be automatically adopted by the second channel for calling again, so that the success rate of the emergency call is improved, and the situation that different channels are adopted for the emergency telephone number in various regions of the world can be adapted.

Second embodiment

In order to further embody the object of the present invention, further illustration is made on the basis of the first embodiment of the present invention.

In this embodiment, before determining the emergency telephone number to be used for making an emergency call, a priority channel corresponding to each emergency telephone number may be pre-selected from the emergency channel and the normal telephone channel;

in this way, after the emergency telephone number to be used for making an emergency call is determined, the first channel can be determined as the priority channel corresponding to the determined emergency telephone number.

Fig. 6 is a schematic diagram illustrating selection of a priority channel corresponding to an emergency telephone number, and as shown in fig. 6, a "please select a priority channel corresponding to the number 911" is displayed on a user interface of the terminal, and two candidate options are displayed, namely an emergency channel and a normal telephone channel; the user can determine the priority channel corresponding to the number 911 as an emergency channel or a normal telephone channel according to actual conditions.

If the user determines the priority channel corresponding to the number 911 as an emergency channel, the first channel may be determined as an emergency channel after determining an emergency phone number that needs to be used when making an emergency call.

It can be seen that, by selecting the priority channel corresponding to each emergency telephone number, the user can make a call according to the actual requirements of the user when making a call by using the corresponding emergency telephone number.

Optionally, when the second channel does not successfully call for M consecutive times by using the emergency phone number, continuing to call for at least one time by using the emergency phone number in the first channel; m is greater than 1; thus, the success rate of calling the emergency telephone number can be improved by alternately using the first channel and the second channel for calling.

Optionally, when the second channel does not use the emergency phone number to make the continuous M calls, after waiting for the set time interval, continuing to use the emergency phone number to make the at least one call in the first channel, so that when the second channel does not use the emergency phone number to make the continuous M calls, the emergency phone number is not immediately used to make the call in the first channel, which can effectively reduce resource consumption of the terminal; in addition, the channel quality of the first channel changes along with the change of time, and when the first channel does not adopt the emergency telephone number to make continuous N times of calls, the channel quality of the first channel is low, so that the channel quality of the first channel is possibly improved when the first channel adopts the emergency telephone number to make a call next time, and the success rate of making a call next time by adopting the emergency telephone number in the first channel is improved.
