The present invention relates to a mobile communication terminal, and more particularly, to a mobile communication system and a communication method for a PoC service that can provide a PoC call history that is absent from the mobile communication terminal.
In general, Push-to-talk On Cellular (PoC) is a service for providing instant multi-party calls, and the PoC standard is established by the Open Mobile Alliance (OMA), a standardization organization, and the 3GPP Internet Protocol Multimedia Sub It is operated on the system {Internet Protocol (IP) Multimedia Subsystem (IMS) and 3GPP2 Multimedia Domain (MMD).
The PoC is a function of incorporating a radio function into a mobile communication terminal such as a mobile phone, and simply drives a means for performing this function, for example, a push-to-torque provided in the mobile communication terminal. By simply pressing a button for to-Talk (PTT), voice can be transmitted to at least one counterpart terminal in 1: 1 or 1: N without any connection procedure.
The user presses a button for a PTT and speaks a word to be transmitted to the other party when voice request is successful. That is, a user who presses the PTT button speaks after obtaining a voice from the PoC server. At this time, the PoC server transmits the voice signal to a terminal of a designated group or all terminals respectively.
In the above-mentioned Push-to-talk On Cellular (PoC) service, a user who obtains a voice in a voice transmits a voice to terminals within a specified group. If there is a receiver that cannot participate in a PoC call, such as when the terminal is placed elsewhere, the receiver has no way of knowing the details of the PoC call between people except themselves.
Accordingly, an object of the present invention is to provide a mobile communication system and a communication method for a PoC service that can overcome the limitations of the prior art as described above and provide a missed PoC call history.
In order to achieve the above object, a mobile communication system for a Push-to-talk On Cellular (PoC) service according to the present invention, the first to initiate a push-to-talk On Cellular (PoC) call to obtain a right to speak; 1 mobile communication terminal; A communication network including a PoC server receiving a PoC call request from the first mobile communication terminal and granting a voice; And at least one mobile communication terminal included in a first group that receives a call transmitted from a first mobile communication terminal through the PoC server, wherein the PoC server includes mobile communication terminals included in the first group. The voice mail of the first group of mobile communication terminals is stored in the voicemail box of at least one mobile communication terminal that does not participate in the PoC call.
In order to achieve the above object, a communication method of a mobile communication system for a PoC service according to the present invention includes a process for requesting a talk right for a Push-to-talk On Cellular (PoC) call from a mobile communication terminal to a server; ; Transmitting the requested talk right from the server to the mobile communication terminal and transmitting a call for initiating PoC call to the mobile communication terminals in the group; Checking whether there is a member in a group that the server cannot participate in the PoC call; If there is a member in the group that did not participate in the PoC call, the server comprises the step of storing the content of the PoC call between the members participating in the PoC call in the voicemail box of the member.
Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.
In describing the present invention, when it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.
1 is a block diagram illustrating a configuration of a mobile communication system 100 for a push-to-talk on cellular service (PoC) according to an embodiment of the present invention.
As shown in FIG. 1, the mobile communication system 100 includes a first
The
Accordingly, the
The user of the mobile communication terminal receiving the short message may check the received message and connect to a voice mailbox to listen to the stored conversation.
Although not shown, the
2 is a flowchart illustrating a communication method of a mobile communication system for a PoC service according to an embodiment of the present invention.
As shown in FIG. 2, when a talk right for a PoC call is requested from the first one mobile communication terminal (S210), the PoC server of the communication network receiving the talk right request grants a talk right to the mobile communication terminal (S220). In operation S230, a call for initiating a PoC call is transmitted to at least one mobile communication terminal included in the corresponding group. At this time, the PoC server does not receive the call or refuses to participate in the PoC call to determine whether there is a mobile communication terminal that does not participate in the PoC call (S240).
As a result of the determination, when there is a mobile communication terminal that does not participate in the PoC call, as the mobile communication terminal receiving the call participates in the PoC call and starts a conversation (S250), the mobile communication terminal participating in the PoC call of the group The communication contents transmitted and received between the two are stored as voice data in the voice mailbox of the mobile communication terminal not participating in the PoC call (S260). In this case, the PoC server may transmit a signal to display an icon or text indicating that the missed call is in progress on the display window of the mobile communication terminal not participating in the PoC call.
When the storage is completed, the PoC server transmits a short message indicating that the PoC call contents have been stored in the voicemail box to the mobile communication terminal not participating in the PoC call through the communication network (S270).
The user of the mobile communication terminal receiving the short message may access a voice mailbox and listen to a PoC call content which he / she has not participated in (absent).
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the scope of the present invention .
For example, for the protection of personal information, considering that the users who participated in the PoC call do not want to store the contents of the call and deliver it to the absentee, the contents of the call are only allowed with the consent of the mobile communication terminals participating in the PoC call. You can also store it for delivery. In addition, an icon, text, or voice indicating that a call is recorded and being transmitted to an absentee may be output from mobile communication terminals participating in a PoC call.
Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
As described above, the mobile communication system for the PoC service and the communication method thereof according to the present invention overcome the limitations of the prior art in that the receiver who cannot participate in the PoC call has no method of listening to the PoC call history between others. In addition, there is an effect of providing a convenience to a user who can provide a missed PoC call history.
