Description

Emergency number matching method and matching device

Technical field

The present invention relates to the field of mobile communication technologies, and in particular, to an emergency number matching method and a matching device when a mobile terminal has a card.

Background technique

In daily life, users of mobile terminals may encounter some situations (such as natural disasters, car accidents, robberies, etc.), and need to call the emergency number in the local emergency number list through the mobile terminal for help. At present, the identification of an emergency telephone number is usually to store a fixed list of emergency numbers in the terminal system, such as police, fire, ambulance, etc., when the number dialed by the user falls within the emergency number list, regardless of What state the terminal is in at the time (such as a keyboard lock, no SIM card, no service, etc.), the terminal system will allow the emergency number to be dialed and try to connect to the emergency telephone service.

The emergency number list in the terminal is derived from three parts: the first part comes from the emergency number sent by the mobile network registered by the terminal; the second part comes from the subscriber identity module (SIM, Subscriber Identity Module) card inserted in the terminal equipment. The emergency number carried; the third part comes from the emergency number preset by the terminal itself. At present, most mobile networks no longer send emergency numbers to terminals that register with the network, and many SIM cards issued by operators do not carry emergency numbers. Therefore, the list of emergency numbers in the terminal is currently large. Some of them are composed of the emergency number preset by the terminal itself, and the emergency number preset by the terminal itself can still be dialed when the SIM card is not inserted or the service is limited.

The emergency numbers of different countries or regions in the world are different. The emergency number preset by the terminal itself is usually preset according to the place of sale of the terminal. For example, the mobile phone sold in China will preset 110 (匪警), 119 ( Fire alarm), 120 (first aid) and other emergency numbers; while the mobile phone sold in the United States will preset the 911 alarm number; the mobile phone sold in the UK will preset the 999 alarm number; the mobile phone sold in Germany will preset 110 (alarm). Emergency numbers such as 112 (fire alarm); mobile phones sold in India will be preset with emergency numbers such as 100 (alarm), 101 (fire), 102 (first aid).

Emergency numbers vary from country to country and configurations are inconsistent. The same is 110, it is tight in China. An urgent number, but in other countries it may be an operator service number and cannot be treated as an emergency number.

Generally, when the mobile terminal is performing international roaming, the current emergency number configuration method may cause the mobile terminal to be unable to dial the emergency number of the roaming place. For example, when the mobile terminal roams from China to India, the mobile terminal cannot dial 119. Switch on the fire alarm in India. This may cause irreparable damage to the personal and property of the mobile terminal user.

The best way to implement the invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be specifically described with reference to Figs.

The mobile terminal can be implemented in various forms. For example, the terminals described in the present invention may include, for example, mobile phones, smart phones, notebook computers, digital broadcast receivers, personal digital assistants (PDAs), tablet computers (PADs), portable multimedia players (PMPs), navigation devices, and the like. Mobile terminal, Those skilled in the art will appreciate that configurations in accordance with embodiments of the present invention can be applied to fixed types of terminals in addition to components that are specifically for mobile purposes.

After the mobile terminal is powered on, it automatically performs network search and initialization, and connects to the communication system through the base station. The communication system can be a global mobile communication system (Global System for Time Division Multiple Access (TDMA)). Mobile Communications, GSM), general packet radio service (GPRS) or enhanced data rates for GSM evolution (EDGE), which is commonly known as 2G network. Alternatively, the communication system may also be a Universal Mobile Telecommunications System (UMTS) using Wideband Code Division Multiple Access (WCDMA), which is commonly known as a 3G network. Alternatively, the communication system may also be a long-term evolution using orthogonal frequency-division multiplexing (OFDM) and/or orthogonal frequency-division multiple access (OFDMA). System (Long Term Evolution, LTE) (such as 3GPP Rel-8/9/10 standard), Advanced Long Term Evolution (LTE-A) (such as 3GPP Rel-11 standard) or the successor of advanced long-term evolution system That is what we call the 4G network. The communication system is not limited to the above, and any system that can provide communication services for mobile terminals is included in the scope of the communication system of the present invention.

Both GSM and WCDMA are based on the GSM-MAP core network, and the GSM network can be smoothly evolved to the WCDMA system. At present, many countries in Europe, Asia and Africa have established WCDMA systems. The so-called international roaming between WCDMA and GSM refers to a WCDMA (GSM) network in which a GSM (or WCDMA) user roams abroad, and provides a service service by using a visited WCDMA (GSM) network.

Due to the differences in the development of various countries, for example, some countries only have GSM networks (such as China), while others only build WCDMA networks (such as Japan), but not GSM networks. To this end, the 3GPP TS 22.100 specification states that WCDMA terminals should be able to support access to WCDMA networks via GSM SIM cards. Of course, at this time, the WCDMA network can only provide users with the services that the GSM system can provide (WCDMA-specific services, such as video and high-speed data communication cannot be provided). Whether the user can access the WCDMA network through the GSM SIM card is controlled by the WCDMA network operator. At the same time, the 3GPP TS 22.101 specification states that UMTS The system should allow WCDMA users to access the GSM network through the GSM terminal.

The Universal Integrated Circuit Card (UICC) is a removable smart card used to store information such as user information, authentication keys, phone books, and short messages. In the GSM and 3GPP specifications, users who want to use various services normally must rely on the UICC card in the mobile terminal. If there is no UICC card in the mobile terminal, the user can only use the emergency call service (for example, 110, 119). A UICC card is a general term for a smart card that defines physical characteristics. The UICC card can include a variety of logical applications, such as a Subscriber Identity Module (SIM), a Universal Subscriber Identity Module (USIM), and other Application (e-wallet, etc.).

The SIM card is a smart card used by mobile terminals in the GSM network, and is used to store various parameters and related user information, such as user subscription information, authentication keys, user preference information, and short messages. The SIM card contains the following information: 1. International Mobile Subscriber Identity (IMSI): User identity for access authentication. 2. Mobile Subscriber ISDN Number (MSISDN, Mobile Subscriber ISDN Number): mobile subscriber's mobile number 3, key Ki, encryption algorithm A3, A8, used for authentication 4, mobile country code (MCC, Mobile Country Code), attribution MACMN Mobile Network Code (MNC): Network ID.

The USIM card is used in a WCDMA network to store user subscription information, authentication information, payment methods, user short messages, and the like. The USIM card contains the following information: 1. International Mobile Subscriber Identity (IMSI): The IMSI is a unique identifier assigned to each user. The identifier is invisible to the user, but is visible. IMSI is used as a user ID for authentication purposes. Its private user identity is equivalent to IMSI in the IP Multimedia Subsystem (IMS). 2. Mobile Subscriber ISDN Number (MSISDN): stores one or more telephone numbers assigned to the user in the domain. Its public user identity in IMS is equivalent to MSISDN. 3. Encryption Key (CK, Cipher Key) and Integrity Key (IK, Integrity Key): These keys are used for encryption and integrity protection of data in the air interface. The USIM stores the keys used in the circuit domain and the packet domain separately. 4. Short Message Service (SMS): The USIM can store short messages and related data, such as sender, receiver, status, and so on. 5. Short message parameters: This field is used to store configuration data related to SMS services, such as SMS center address and supported protocols. and many more. 6. Multimedia message service (MMS) user connectivity parameter: This field is used to store configuration data related to the MMS service, such as the MMS server address and the MMS gateway address. 7. MMS User Preferences: This field is used to store user preference information related to the MMS service, such as sending a report flag, priority, expiration information, and the like.

Compared with the one-way authentication of the SIM card (network authentication user), the USIM card authentication mechanism adopts two-way authentication (in addition to the network authentication user, the user also authenticates the network), which has high security. Each contact in the USIM card phonebook can correspond to multiple numbers or nicknames compared to the SIM card phonebook. Compared with the SIM card interface rate, the USIM card interface rate is greatly improved (230 kbps). Compared to SIM card support for logic applications, USIM can support 4 concurrent logic applications at the same time.

At present, the UICC card generally includes two modules, USIM and SIM. At this time, it is called a composite USIM card (it can be compatible with GSM terminals and WCDMA terminals). If the UICC includes only the USIM module, it is called a pure USIM card. The WCDMA terminal has backward compatibility on the machine card interface, and is compatible with USIM cards (composite USIM cards and pure USIM cards) and GSM SIM cards. The GSM terminal is compatible with the GSM SIM card and the WCDMA composite USIM card, and is not compatible with the pure USIM card. WCDMA dual-mode terminals can be connected to a GSM wireless network or a WCDMA wireless network regardless of whether a SIM card or a USIM card (a composite USIM card or a pure USIM card) is inserted. The GSM terminal can only be connected to the GSM wireless network by inserting a SIM card or a composite USIM card. The SIM card can be applied to GSM, WCDMA, TD-SCDMA systems. The USIM card can be applied to GSM, WCDMA, and TD-SCDMA systems.

The base station of the communication system sends a broadcast system message, and the broadcast system message includes three types: MIB (Master Information Block), SB (Scheduling Block), and SIB (System Information Block). The main information block MIB includes a PLMN (Public Land Mobile-communication Network) information, and the public land mobile network PLMN is established by the government or its approved operator to provide the land mobile communication service for the public. The operating network, each operator's network has a corresponding PLMN number for identification, and the public land mobile network PLMN ID consists of two parts, namely the mobile country code MCC (mobility country code) and the operator code MNC (Mobile Network Code) ), MCC country code can uniquely identify a country.

The invention obtains the country code (MCC) through the network registered by the mobile terminal, and then matches the local emergency number, so that the mobile terminal can obtain the correct local emergency number in different countries. The code and the mobile terminal can also match the correct emergency number in the case of a short off-network or a flight mode, ensuring a correct match between the emergency number and the country.
