Description
Technical field
The present invention relates to a kind of method and portable terminal thereof that obtains emergency call information, more particularly, relate to a kind of method and portable terminal thereof that obtains emergency call information by air interface.
Background technology
Along with the fast development of mobile communication technology, portable terminal has become the instrument of the most important and most convenient of people's communication.Particularly in the environment of emergency, utilize portable terminal to initiate urgent call and report to the police or cry for help, be the most convenient and one of method efficiently.According to international rule, no matter whether portable terminal is plugged the SIM/USIM card, whether the perhaps current sub-district of being stationed is its HPLMN (Home Public Land Mobile Network, home public land mobile network), as long as portable terminal is within the wireless coverage of its access technology of supporting, portable terminal all must can be initiated urgent call.These rules provide support for conveniently initiating urgent call.
In order to realize above-mentioned requirements, and improve the priority of initiating urgent call, in the mobile communication standard, defined the particular message " Emergency Setup " (urgent call foundation) of initiating urgent call separately at present.Processing to urgent call is: when the user dials urgent call, at first key in emergency telephone number, portable terminal judges whether this number is the local emergency telephone number of supporting then.If then search the type of this urgent call, and fill it into urgent call and set up and send to network in the message.Network terminal then decides how to handle this urgent call according to the type that urgent call is set up in the message.The emergency telephone number that the user dials does not need to be sent to network terminal.
At present, the regulation emergency telephone number is stored on portable terminal and the SIM/USIM card in the agreement.
Describe the user below with reference to Fig. 1 and use portable terminal to dial the process of emergency telephone number, Fig. 1 shows the flow chart of the urgent call initiation process of conventional method.
With reference to Fig. 1, when the user in case of emergency, in step 101, the user imports emergency telephone number in portable terminal, judge whether insert the SIM/USIM card in the portable terminal in step 102 subsequently, if insert, then judge in step 103 whether card is effective, if card effectively, then judge on the card in step 104 whether emergency call information is arranged, if emergency call information is arranged,, read this emergency call information then in step 105, and the telephone number of input and the emergency call information on the card are compared in step 106, judge in step 108 whether this Enters Number is emergency telephone number subsequently, if, then in step 111, from emergency call information, obtain types value, in step 112, the urgent call type is filled in the urgent initiation information subsequently, and initiates urgent call.If in step 102 portable terminal, do not insert the SIM/USIM card, described card is invalid, perhaps not emergency telephone number, then proceed to step 107 and compare with number that will input and the emergency call information on the portable terminal step 108 determining step 106 Entering Number relatively.Then,, judge whether the number of input is emergency telephone number,, then initiate normal call in step 110 if not emergency telephone number in step 109.Otherwise, in step 111, from emergency call information, obtain types value, and in step 112 the urgent call type be filled into urgent call and set up in the message and initiate urgent call.
Because the number and the implication of each national urgent call are not quite similar, and have caused the evaluation algorithm more complicated of emergency telephone number.Three kinds of situations shown in the table 1 below needing to distinguish:
(1) there is not the SIM/USIM card;
(2) the SIM/USIM card is arranged, but do not preset any emergency telephone number in the SIM/USIM card;
(3) the SIM/USIM card is arranged, and preset emergency telephone number in the SIM/USIM card.
Table 1
| There is not the SIM/USIM card | The SIM/USIM card is arranged, but do not preset any emergency telephone number in the SIM/USIM card | The SIM/USIMM card is arranged, and preset emergency telephone number in the SIM/USIM card | |
| Do not have the urgent call of urgent call type | 000，08，112，110， 118，119，911，999 | 112，911 | 112，911 |
| Have the urgent call of urgent call type | X | X | (for example, the CMCC plan needs the emergency telephone number 110 of support to the emergency telephone number that operator supports in the future: robber and police; 119: fire alarm 120: first aid) |
| Ordinary call | All other numbers | All other numbers | All other numbers |
Although existing algorithm is very complicated, still can't solve all problems:
(1) when not inserting the SIM/USIM card in the portable terminal, mobile communication regulation and stipulation portable terminal only thinks that 000,08,112,110,118,119,911,999 these several numbers are emergency telephone numbers, therefore in China, when not inserting the SIM/USIM card in portable terminal, the urgent call of 120 first-aid centres can't be initiated;
(2) when having inserted the SIM/USIM card, but when not presetting any emergency telephone number in the SIM/USIM card, mobile communication regulation and stipulation portable terminal only thinks that 112 and 911 are emergency telephone number, and the user dials 110,120 and initiates ordinary call, does not reach to initiate urgent call to guarantee the effect of call priority;
(3) when having inserted the SIM/USIM card, and when presetting emergency telephone number in the SIM/USIM card, if the network of operator is not supported the use of this emergency telephone number, the user still can't initiate urgent call.For example, at present the network of CMCC (China Mobile) is not also supported the urgent call of China such as 110,120, like this, can not preset 110,120 as emergency telephone number on the SIM/USIM card that China uses.But CMCC clearly will support the various urgent calls (110,120 etc.) of China during expression network upgrade in the future.Till that time, the SIM/USIM card in the portable terminal all needs to be updated to the SIM/USIM card of supporting these urgent calls now, otherwise, still can't initiate urgent call.This has brought very big inconvenience to the user.In addition, when mobile phone users roams into other when country, if the emergency telephone number of storing in local emergency telephone number and the SIM/USIM card is different, then this user can't normally initiate the urgent call of locality, has a strong impact on user's use.
Therefore, above-mentioned defective has had a strong impact on mobile terminal user and has effectively used emergency call function.
