Description

The method of adding IP automatically by mobile phone dialing

Technical field:

The invention relates to the field of call control in the wireless communication field, in particular to a method for a mobile phone to automatically convert a user's call from a circuit switching type to an IP call without user intervention.

Background technique:

Voice over IP is a mature technology, and the business of making IP calls on mobile phones has been widely used. At present, for mobile operators, all they provide to users are IP services. However, the average income of most mobile phone users is relatively low, and the call cost of mobile phones is relatively high. Therefore, the cost of mobile phone calls is one of the important factors restricting the further development of mobile communications.

Compared with traditional calls, dialing IP calls on mobile phones can greatly save users' call charges. However, it is necessary to dial an IP access number to make an IP call. Different operators provide different IP access numbers, and users may roam, which brings a lot of trouble and inconvenience to users when using this service. For example: there is a user who lives in a certain place, because the work must go back and forth between the city where he lives and other cities for many years. The number of the city where you live or travel frequently, as shown in Table 1 below: serial number Name Telephone 1 Home 0755 3348884 2 Miss Zhu 021 64708411 3 Mr Song 010 64708412

When the user is in the city where he lives, he only needs to dial the number according to the phone book to directly dial the phone number at home. The call is charged as a local call; Long-distance calls are charged. If you make an IP call, you must dial an IP access number, such as: 17951, and then manually enter the phone number. At this time, the phonebook on the user's mobile phone should be changed as shown in Table 2:

serial number Name Telephone 1 Home 0755 3348884 2 Miss Zhu   17951 021 64708411 3 Mr. Song   17951 010 64708412

In this way, the user can conveniently directly dial the corresponding number from the phone book when he is in his place of residence.

However, when the user arrives in other cities (such as a city with a long-distance area code of 021), the user's phonebook needs to be modified according to Table 3. If the user needs to make a call to his home, he also needs to manually input the IP access Number 17951 + home number, or change all the phone numbers in the phone book, as shown in Table 3 below: serial number Name Telephone 1 Home 17951 0755 3348884 2 Miss Zhu 021 64708411 3 Mr Song 17951 010 64708412

When the user returns to his city of residence again, some phonebooks of the user's mobile phone need to be revised again, otherwise, manual dialing is required again. In addition, if the user replaces a new SIM (Subscriber Identification Module) card and changes the selected service operator, then the corresponding IP access number also changes, and the user must manually check the number stored in the mobile phone book. It is very troublesome and inconvenient to modify one or even dozens or hundreds of phone numbers.

Invention content:

The purpose of the present invention is to provide a method for automatically dialing IP by mobile phone dialing, which overcomes the need to manually input numbers when dialing IP phones, and when selecting different IP access numbers provided by different operators, it is difficult for users to remember, or It takes a lot of trouble to change the phone book. It can automatically identify the type of the dialed number and the operator to which the Subscriber Identification Module (SIM card) belongs. Without user intervention, it can automatically add IP to realize the simplification of mobile phone dialing , intelligent and user-friendly, user-friendly.

The purpose of the present invention is achieved through the following technical solutions:

A method for automatically dialing an IP by a mobile phone, comprising:

Step 1: The mobile phone judges the call type when the user dials;

Step 2: The mobile phone further judges the mobile service operator of the user; obtains the IP access number provided by the operator to the user;

Step 3: The mobile phone adds the obtained IP access number before the original outgoing number, and replaces the original outgoing number with the combined new outgoing number;

Step 4: The mobile phone makes a dial call.

The above method also includes initializing the mobile phone, and the specific setting steps are: when the user uses the mobile phone for the first time, the mobile phone provides the user with the selection function of whether to dial the IP; if the user chooses the function of dialing the IP, further request The user inputs the area code of the city where he is currently located; the mobile phone is set according to the user's selection and the input city area code.

The call types mentioned above at least include: a mobile user calls an ordinary local call, a mobile user calls a domestic long-distance call, a mobile user calls an international long-distance call, and a mobile user calls a mobile user.

The mobile phone judges the call type when the user dials a number through the following steps:

Step 1: Read the length of the called party’s number. If the length of the called party’s number is less than or equal to the maximum length of an ordinary local call, it is considered that the call belongs to the type of a mobile user calling an ordinary local call, otherwise turn to the second step;

Step 2: Take out the current city area code stored in the mobile phone, and compare the number with the same number of digits before the called party number with the current city area code according to its length value. If they are equal, it is considered that this call belongs to a mobile user calling ordinary Local call type, otherwise turn to the third step;

Step 3: If the called number starts with the national identification code, it is considered that the call belongs to the type of international long-distance calling by the mobile user, otherwise go to the fourth step;

Step 4: If the called number starts with "0", go to step 6; otherwise, go to step 5;

Step 5: If the length of the called number is equal to the length of the mobile user number provided by the mobile operator, and the called number starts with the mobile special number provided by the mobile operator, then it is considered that this call belongs to the mobile user calling mobile user type, otherwise it is Mobile users call ordinary local calls.

Step 6: After removing the "0" at the beginning, if the length of the called number is equal to the length of the mobile subscriber number provided by the mobile operator, and the called number starts with the mobile special number provided by the mobile operator, then the call is considered to belong to the mobile The user calls the mobile user type, otherwise the mobile user calls the domestic long-distance type.

In the above-mentioned step 1, when the mobile phone judges the call type when the user dials, if the call type belongs to the mobile user calling an ordinary local call or a local mobile user, the call is directly sent out.

In the above step 1, when the mobile phone judges the call category when the user dials, if the call category belongs to a mobile user calling a remote mobile user, then go to step 2.

The specific operation of step 2 above is as follows: the mobile phone first takes out the network number of the current network; uses the network number to search in the network number and operator relationship comparison table to obtain the operator to which the current mobile phone belongs; finally according to the operator The provided IP access number gets the required IP access number.

As mentioned above, the dial-up call sent by the mobile phone complies with the GSM04.08 wireless interface layer three protocol standard in the international wireless communication protocol standard.

The present invention fundamentally solves the problem that a long string of numbers needs to be manually input when making an IP call on a mobile phone, and even if the mobile phone user frequently dials an IP call in a different area, it does not need to modify a large number of numbers stored in the mobile phone. Phonebook information; it overcomes the need to manually enter numbers when dialing IP phones, choose different IP access numbers provided by different operators, users are difficult to remember, or need to change a lot of phonebook troubles; through automatic identification of dialed number types and Automatically identify the operator to which the SIM card belongs, and automatically dial IP without user intervention, realizing the simplification, intelligence and humanization of mobile phone dialing, which is convenient for users; completely solves the cumbersomeness of dialing IP calls on mobile phones The problem; in terms of economy and ease of use, it meets the user's convenience requirements to the greatest extent.

Below in conjunction with accompanying drawing and specific embodiment, technical solution proposed by the present invention is described in further detail:

Description of drawings:

Fig. 1 is the implementation flowchart of the method for automatically dialing IP in mobile phone dialing according to the present invention.

Fig. 2 is a flow chart of the processing procedure for judging the category of the call in the method of automatically adding IP to the mobile phone dialing in one embodiment of the present invention.

FIG. 3 is a flow chart of judging the mobile operator to which the user belongs and obtaining the IP access number in the method for automatically adding IP by mobile phone dialing in an embodiment of the present invention.

Detailed ways:

In a preferred embodiment of the present invention, when the user uses the mobile phone for the first time, the mobile phone can provide the user with the selection function of dialing IP; The purpose is to enable the user to choose the function of dialing IP, and on this basis, the user further inputs the area code of the current city; the mobile phone sets the relevant settings for dialing IP calls according to the user's choice and the input city area code. This setting is stored in the phone as the basic setting for future IP calls.

According to the GSM04.08 wireless interface layer three protocol standard in the international wireless communication protocol standard, when the mobile terminal (Mobile Station) initiates a call as the calling party, the call control entity of the mobile terminal (Mobile Station) first requests the mobility management ( Mobility Management) sublayer establishes a mobility management (Mobility Management) sublayer connection; when the mobility management sublayer connection is established, the call control entity of the mobile terminal sends SETUP information to the peer layer at the network end , the SETUP information contains all the information that the network needs to process, and it contains the address of the called party. The network end judges whether the mobile terminal requests an ordinary circuit-switched call or an IP call in this call according to the called party address in the SETUP information. If the called party's address begins with the IP access provided by the operator, the network side treats the call as an IP call; otherwise, the network side considers the call to be a normal circuit-switched call.

Referring to FIG. 1 , before actually initiating a call each time, that is, before filling in the information contained in the SETUP signal and sending it, the call must be classified first. The call proposed by the present invention has at least four types according to the type: a mobile user calls an ordinary local call, a mobile user calls a domestic long-distance call, a mobile user calls an international long-distance call, and a mobile user calls a mobile user.

Referring to Figure 2, the operation of classifying call types is divided into the following steps:

The first step: read the length of the called party's number, if the length of the called party's number is less than or equal to the maximum length of an ordinary local call, then it is considered that this call belongs to the type of a mobile user calling an ordinary local call (for example: the number of an ordinary local call in my country The length is within eight digits, therefore, if the length of the called party’s number is less than or equal to eight digits, it can be considered that the call belongs to the type of a mobile user calling an ordinary local call), otherwise turn to the second step;

Step 2: Take out the current city area code stored in the mobile phone, and compare the number with the same number of digits before the called party number with the current city area code according to its length value. If they are equal, it is considered that this call belongs to a mobile user calling ordinary Local call type, otherwise turn to the third step;

Step 3: If the called number starts with the identification code of the country, for example, the identification code in mainland my country starts with "00" or "+", it is considered that the call belongs to the type of international long-distance call by a mobile user, otherwise go to step 4 ;

Step 4: If the called number starts with "0", go to step 6; otherwise, go to step 5;

Step 5: If the length of the called number is equal to the length of the mobile user number provided by the mobile operator, and the called number starts with the mobile special number provided by the mobile operator, then it is considered that this call belongs to the mobile user calling mobile user type, otherwise it is Mobile users call ordinary local calls.

Step 6: After removing the "0" at the beginning, if the length of the called number is equal to the length of the mobile subscriber number provided by the mobile operator, and the called number starts with the mobile special number provided by the mobile operator, then the call is considered to belong to the mobile The user calls the mobile user type, otherwise the mobile user calls the domestic long-distance type.

One point that needs to be explained is: the above classification step divides the number that the user misdialed does not exist, or the special number into two categories according to the length less than or equal to the maximum length of the ordinary local call and the maximum length greater than the ordinary local call, but these two Classes all fall into the category of mobile subscribers calling ordinary local calls. Therefore, the above-mentioned classification method covers all situations; and the number dialed by the user must belong to one of the types separated in the above-mentioned classification method, and the number that does not exist in the wrong dial is also dialed according to the above-mentioned classification method. The terminal will check and process, and return an error message to the user.

For example, when user A is in his city of residence (SZ), user A sets the area code currently preset in the mobile phone to the area code of his city of residence (SZ), for example: 0755; at this time, user A manually enters his home phone number 3348884, according to the first step of the above classification method, it can be correctly classified as a mobile user calling an ordinary local call; The area code of the city (SZ) where Mr. user A lives is 0755, and its length is 4, which is the same as the first 4 digits of the home phone number stored in the phone book of user A. The mobile phone still classifies this call as a mobile user calling an ordinary local call. If user A wants to dial the mobile phone 13916349248 of Mr. B in other cities (SH), then no matter user A manually inputs or selects this number from the phone book, the mobile phone is all classified according to the third step. And if user A wants to dial the landline telephone of Ms. (SH)C in his city, then this call is classified as the type of mobile subscriber calling domestic long distance.

And when user A goes on a business trip from his city of residence (SZ) to other cities (SH), user A can change the area code currently preset in the mobile phone to the area code of the city (SH) he arrived on business trip, such as: 021, so if the user When user A dials the home phone number 0755 3348884, the call has been classified as a domestic long-distance call by a mobile user; and when user A dials Ms. C's fixed phone, the call has been classified as a local call by a mobile user.

According to the result obtained by the above-mentioned call type identification, if this call is an ordinary local telephone number or a local mobile subscriber number, the mobile phone does not make any changes to the SETUP information and directly sends a request to set up an ordinary circuit-switched call. Otherwise, it is necessary to convert the ordinary circuit-switched call to an IP call; in order to obtain the IP access number provided by the operator, it is necessary to perform the steps shown in Figure 3:

Referring to Figure 3, in order to obtain the IP access number provided by the operator, the mobile phone first takes out the network number of the current network, and then searches the relationship between the network number and the operator, so as to obtain the SIM card used in the current mobile phone. The operator can finally obtain the IP access number that needs to be added finally according to the IP access number provided by the operator.

For example, the mobile operator of the SIM card on user A's mobile phone is AY. After registration or location update, the network will always send back the network number 0460-00 of the mobile operator AY to the mobile phone. There is a one-to-one correspondence between the operator and its network number, so according to this network number, the mobile phone can correctly obtain that the current operator it belongs to is the mobile operator AY.

After obtaining the information of the operator AY to which the local SIM card belongs, the IP access number provided by the mobile operator AY can be added before the outgoing number to form a new called party number. For example, if the current network number is 0460--01, its mobile operator is mobile operator BY, and the IP access number provided by mobile operator BY, such as "17910", is added before the original dialed number to form a new Address of the called party; if the current network number is 0460-00, its mobile operator is mobile operator AY, and the IP access number "17951" provided by mobile operator AY is added before the original dialed number to form a new Called party address. The software call control entity in the mobile phone sends out the newly formed SETUP information, and the network side receives the SETUP information, and processes this call according to the IP access number in front of the called party number, in accordance with the IP call method; User intervention, the mobile phone automatically dials the IP function.

The method for automatically dialing IP by the mobile phone of the present invention has high reliability, user selectivity, easy implementation, and scalability, and can expand the corresponding operation method according to the improvement of the service provided by the operator to obtain a good implementation and applications.

To sum up, the method for automatically adding IP to this mobile phone dialing proposed by the present invention has given users more flexibility and selectivity, brought more economy and practicality to users, and made mobile phones gradually become more intelligent. The trend of humanization and humanization is developing.

The above embodiments are only used to illustrate the present invention without limitation, although the present invention has been described in detail with reference to the above preferred embodiments, those of ordinary skill in the art should understand that the present invention can be modified, deformed or equivalently replaced without departing from The spirit and scope of the present invention should be included in the claims of the present invention.
