Description

Selective Receiving method for mobile terminal

The present invention relates to a mobile communication service, and more particularly, to a selective reception method of a mobile terminal using a minor number used in a mobile terminal to which IS-95B or above is applied.

In general, a number system applied to an IS-95 code division multiple access (hereinafter, referred to as CDMA) mobile terminal is configured to set a call by assigning only one number to one terminal.

 That is, the current CDMA scheme is configured such that only one telephone number including a mobile identification number is assigned to one terminal.

However, some mobile communication services provide a two-numbered service method by forming a separate additional network in the existing CDMA network and selectively notifying the terminal after determining whether the incoming number is a major or minor number. Doing.

When using the two-number service method using the additional network, the sub-number defined by the two-number service can be switched to the incoming or voice mail by the user's selection.

1 is a block diagram of a communication system for two-number service according to the prior art.

Referring to FIG. 1, after an incoming signal is transmitted from the calling terminal 10, the incoming signal is switched by the exchange 11 to reach the called terminal 12.

At this time, the communication system connecting the calling terminal 10 and the called terminal 12 has a separate additional network to determine which number the incoming signal from the calling terminal 10 is transmitted through.

Here, the signal received by the main number is received by the main number of the destination terminal 12, the signal received by the minor number is received by the destination terminal 12 as the main number or the voice mail of the minor number according to the user selection (VMS) 13 is sent.

In this case, the exchange 11 switches signals transmitted through the minor number.

As the conventional CDMA mobile terminal is given a number to one terminal, it uses a method of using multiple networks by using an additional network to selectively distinguish when receiving a call. There is a problem causing overload.

Second, there is a problem that costs are added for a separate additional network configuration.

Third, since the non-standardized method is used, there is a problem in that compatibility with other networks is not compatible.

Fourth, there is a problem that it is difficult to efficiently manage the number resources due to the assignment of a plurality of numbers.

Disclosure of Invention An object of the present invention is to provide a selective reception method of a mobile terminal which enables selective reception using a minor number used in a mobile terminal to which IS-95B or more is applied.

Another object of the present invention is to provide a selective reception method of a mobile terminal to automatically perform a specific reception operation according to an arbitrary minor number using a minor number used in a mobile terminal to which IS-95B or higher is applied.

According to an aspect of the present invention for achieving the above object, receiving a call message from the first terminal and setting up a call between the first terminal and the second terminal, the call message includes the call consecutive message information The second terminal waits for a predetermined time to receive the calling consecutive message, and when the second terminal receiving the calling consecutive message sets the minor number to be used, removes the minor number information included in the calling continuous message. And providing to the terminal user, and selectively maintaining or releasing a call setup according to the minor number.

Preferably, the minor number maintains or releases a call setup to each first terminal user group or to a first terminal user group using at least one or more minor numbers.

Then, the user stores information on whether to maintain or release the call setup to each of the first terminal user or the first terminal user group according to the minor number in the second terminal, and allows the user to retrieve the maintenance or release information. By maintaining the call setup to each of the first terminal user or the first terminal user group according to the minor number, the user stores information on a specific reception operation according to the corresponding minor number in the second terminal, and retrieves the reception operation information. Do it.

In addition, when the call continuation message is not received or the sub-number function of the second terminal is not selected, the second terminal releases the set call.

In the present invention, a call is processed using a subnumber system defined in the North American Code Division Multiple Access (CDMA) standard of IS-95B or above. In this subnumbering system, the communication system identifies and notifies the destination terminal through the main number, and the subnumber is transmitted to the destination terminal regardless of the number, and the destination terminal receives a reception operation according to the subnumber according to the purpose. Process.

In addition, according to the IS-95B standard, the present invention enables interworking with wired terminals such as an integrated information communication network (ISDN) when the number system of a network service access point (NSAP) is followed.

Hereinafter, a configuration and an operation according to an exemplary embodiment of the present invention will be described with reference to the accompanying drawings.

2 is a flowchart illustrating a selective reception method of a mobile terminal using a minor number according to the present invention.

Referring to FIG. 2, the originating terminal transmits an origination message including a major number to a called terminal capable of normal operation of the IS-95B call processing message.

The purpose of using the called terminal capable of normal operation of the IS-95B call processing message is to enable the identification of the sender and the selective reception of the called terminal according to the sender.

The called terminal establishes a call according to the main number with the calling terminal. (S11)

Then, it is determined whether the outgoing message includes call continuation message information. (S12) An origination continuation message is one of messages used in reverse IS-95B or above. When a terminal attempts to make a call in a general call processing process, the terminal transmits a variety of information in an origination message, which is a message transmitted to the mobile station. In addition, it is necessary to send additional information to the mobile station. When present, the additional information is included in the calling sequence message and transmitted.

If the call continuation message information is not included, the call setup is set as in the conventional general call. (S13)

However, if the calling message includes calling consecutive message information, the called terminal and the called terminal to which the call is established enter the communication substate of the communication channel state of the called terminal according to the standard of IS-95B or higher. Wait for a random time for the Origination Continuation Message to be transmitted (S14).

 After a predetermined time, it is determined whether the call continuation message is included in the call party subaddress information subaddress of the called terminal (S15).

Then, it is determined whether the called terminal sets the minor number function selection according to the present invention.

If the calling sequence message is not received even after the standard waiting time or if the called terminal user does not select the minor number function, the set call with the calling terminal is released (S17).

However, when the call consecutive message is received within the standard waiting time and the called terminal user selects the minor number function, the minor number by the minor number information record is notified to the user through the user interface (S18).

The called terminal user performs the following operation according to whether or not the minor number information record of the calling consecutive message is included.

The called terminal selectively determines whether to maintain a call setting (S20) or release a set call (S17) according to an arbitrary minor number included in the minor number information record, or is included in the minor number information record. Different receiving operations are automatically performed according to any minor number present.

The user who wants to use the called terminal to make such a selective or automatic reception operation selects a desired reception operation according to an arbitrary minor number through a user interface or a separate button and stores the reception operation in advance according to the main number. After the call is set up, the specific receive operation according to the relevant minor number is automatically performed.

Alternatively, the user selectively sets a desired caller and call by storing and determining whether to maintain or release a call set according to an arbitrary minor number through a user interface or a separate button.

In order for such selective reception to be made, the called terminal is assigned two or more minor numbers in advance, and if a selective response is required, the called terminal responds only when the incoming number is received and does not respond to a number except the minor number or a different number. Do not.

 For example, when the user selects the sender identification function, the caller is identified and the call is set.

However, if the user does not select this sender identification function, it operates in the same manner as a general mobile terminal number system.

In this case, if the subnumber identifiers are diversified, each user request can be differentiated by the subnumber respondents.

For example, if a recipient group is created in the called terminal and the two-digit minor number is grouped into the first digit number, only the caller corresponding to the group may be received.

On the other hand, if the destination terminal uses a plurality of minor numbers, the previously stored information for each minor number is notified through the destination terminal user interface, and the user is asked whether to select the plurality of minor numbers.

In processing the minor number information field including the minor number information record of the called terminal, the called terminal may designate a minor number system according to IS-95B, or a network service access point (hereinafter abbreviated as NSAP) or user definition ( User Specified).

This minor numbering system is implemented differently depending on the service provider.

The method of using a subnumber system by a network service access point (NSAP) of the subnumber system can be linked with a wired network terminal such as an integrated information communication network (ISDN).

3 is an integrated ISDN numbering system based on the E.164 standard that can be supported by a network service access point (NSAP) numbering system.

Referring to FIG. 3, a number system of an integrated information communication network (ISDN) includes a national destination code, a subscriber number, and a sub-address.

Accordingly, when a called terminal having a number system similar to the Integrated Services Digital Number (ISDN) numbering system receives a minor number, the called terminal informs the user of the calling party number and the minor number through the called terminal user interface and asks whether to receive it. If the user selects it, the call connects normally.

Therefore, the selective reception method of the mobile communication system according to the present invention can be linked not only between mobile terminals but also to terminals in a wired network.

As described above, the selective reception method of the mobile terminal using the minor number according to the present invention has an advantage in that the cost in the system can be greatly reduced by reducing the additional network as compared to the selective call identification method using the existing additional network.

In addition, by enabling the number identification and selection response procedure in the receiving terminal, the processing load of the system is reduced, and whether or not the identification function can be selected by the user's convenience is advantageous in that it can immediately respond to various needs of the user.

In addition, by varying the minor number identifiers based on this function, the user's request corresponding to each minor number can be defined and listed in the terminal to differentiate responders or purposes by subnumber.
