## Title
Method and apparatus for allowing communication within a group

## Abstract

A method and apparatus exchange information within a predefined group of telecommunication terminals with each of the group being utilized by a user by forming a voice message by one of the group; communicating the voice message to the remainder of the group via instant message communication; and converting the instant message communication to a voice conferencing communication that includes all members of the group that remained part of the instant message communication.

## Background
TECHNICAL FIELD
This invention relates to communication and messaging systems.
BACKGROUND
Due to increased Internet bandwidth to the home, environmental considerations, and economic factors, more and more people are starting to work at home rather than to go into a more traditional work place. This trend cuts across a variety of industries and governmental entities. Whereas, working at home does allow the individual to avoid commuting and to have a larger and quieter work space, an individual who works at home does not have the group experience. In a more traditional office environment where a number of people sit in close proximity, an individual having a question can simply voice the question in a short voice expression and get an immediate response from the group. An individual working at home can set up a conference call to all of the individuals in the group who are remote and ask the same question, but this is a time consuming process.
The other alternative that can be utilized is to send an instant message to the group. The disadvantaged of the instant message is that it requires the individual to type the question and then for people to respond with a written answer. It is well known that for short questions most people prefer to hear the question and respond vocally.
SUMMARY
A method and apparatus exchange information within a predefined group of telecommunication terminals with each of the group being utilized by a user by forming a voice message by one of the group; communicating the voice message to the remainder of the group via instant message communication; and converting the instant message communication to a voice conferencing communication that includes all members of the group that remained part of the instant message communication.



BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 illustrates, in block diagram form, an embodiment of system; and
FIGS. 2 and 3 illustrate, in flowchart form, operations performed by communication terminals in one embodiment.



DETAILED DESCRIPTION
In one embodiment, an individual wishing to ask a question of a predefined group transmits an instant message that utilizes a voice message rather than a text message. Each individual of the group can then respond to the instant message or chose to drop off of a session created by the instant message. The responses from the individuals of the group are transmitted to all members of the group who are still active on the session. At a later point, any active individual of the group can convert the instant message session into a voice conference call.
FIG. 1 illustrates an embodiment. Public switched telephone network 101 interconnects communication devices such as telephone 112 to enterprise switching system 102. Enterprise switching system 102 provides voice and other types of media communication capabilities for communication terminal 114, telephone 116 and TTY terminal 117. One skilled in the art would realize that there could be a plurality of each of these types of devices. Enterprise switching system 102 thus allows a telephone such as telephone 116 to place a call to a telephone connected to the public switched telephone network 101.
Further, enterprise switching system 102 not only allows a communication terminal such as communication terminal 114 to place voice calls, but also access to IM messages via enterprise IM system 106. In addition, a communication terminal such as communication terminal 114 may also gain access to the switching network 104.
Further, communication terminals 103, 106, and 118 are interconnected via switching network 104 to enterprise switching system 102. In addition, enterprise wireless system 121 also provides wireless service normally within a geographic location of an entity.
Enterprise IM system 106 provides a secure IM communication means for users within an entity. Communication terminals 103, 109, and 114 may be geographically dispersed even though they are considered as being part of the enterprise entity.
A user assigned to enterprise switching system 102 may be present on cellular system 119, public switched telephone network 101, enterprise IM system 106, and enterprise wireless system 121. Presence server 107 may be used to receive information concerning on which IM system the user is present, and this information may be stored in presence information database 108. The operations of these systems with respect to user's presence is detailed in U.S. Patent Application Publication 2004/0141594 which is hereby incorporated by reference.
To understand the embodiment illustrated in FIG. 1, consider the following example. Communication terminals 103, 109, 114, and 118 are in a predefined group. Assume that the user of communication terminal 114 has a question which they wish to pose to the other users of the group. The user activates the voice message operation by actuation of one or more keys or curser selections on communication terminal 114. The user then records a short message. After the message is recorded, communication terminal 114 sends this voice message to communication terminals 103, 109, and 118. Advantageously, the message may be sent in an invite message of the session initiation protocol (SIP). SIP is defined in the Internet Engineering Task Force (IETF) Request for Comments (RFC) 3261 “SIP: Session Initiation Protocol”, June, 2002. The short voice message is included in proprietary fields of the invite message.
Whether the message is actually outputted on communication terminals 103, 109, or 118 depends if these terminals are present on network 104, the user has not specified that they wish not to receive such messages at the present time, or the communication terminal is currently performing operations during which it is unadvisable to play a message. One such operation would be if the user of the communication terminal was engaged in an active voice call.
Assume for the example that the user of communication terminal 118 does not wish to respond or be part of any answers concerning the questions it has received. The user terminates the session created by the invite message by striking a particular key, cursor selection, or voice command. Communication terminal 118 then terminates the session, and the proper messages are transmitted back to the other communication terminals of the group.
The users of communication terminals 103 and 109 do respond and may do so simply by speaking their response when the communication terminals are capable of recognizing the onset of voice. Also, in another embodiment, the users of the communication terminals will strike a key to indicate that they are going to record a message. When the message is recorded, it is transmitted to communication terminal 114 and the other communication terminals who are still active on the session. Assume for the sake of the example, that communication terminal 103 transmits a remark or response and the user of communication terminal 109 decides not to respond but to remain part of the session. The response from communication terminal 103 may advantageously be transmitted again in another invite message to communication terminals 114 and 109. The communication terminals 103, 109, and 114 can continue to transmit back and forth these recorded messages or any of the communication terminals can convert the session into an actual voice call by transmitting a re-invite message requesting that a RTP stream be established using standard SIP protocol to communicate the conference call that is now established between communication terminals 103, 109, and 114.
In the previous example, if communication terminal 114 determines that the user of say communication terminal 118 is not present on communication terminal 118 but rather is present on cellular telephone 116, the initial message will be transmitted to cellular telephone 116. Similarly, if a user present on enterprise wireless system 121 as determined by presence server 107, the messages will be transferred to the user on enterprise wireless system 121. Further, it is possible for a user to be utilizing TTY terminal 117 in which case, enterprise switching system 102 will translate the voice message to the text protocol of a TTY terminal.
FIGS. 2 and 3 illustrate, in flowchart form, operations performed by communication terminals in one embodiment. After being started in block 201, decision block 202 determines if the user of the terminal has indicated that they want to transmit an audio question. If the answer is yes, block 203 records the message, and block 204 forms and transmits an invite message with the recorded message in proprietary fields.
After execution of block 204, decision block 206 determines if a response had been received back to the audio question. If the answer is yes, block 207 plays the response before transferring control back to decision block 301 of FIG. 3.
If the answer in decision block 206 is no, decision block 208 determines if the user of the terminal wishes to transfer to voice communication via a conference call by establishing a RTP stream. If the answer is yes, block 209 forms and transmits a re-invite message for a RTP stream before transferring control back to decision block 206.
If the answer in decision block 208 is no, decision block 211 determines if a re-invite message has been received as part of the session to establish a RTP stream so that a conference call can take place. If the answer is yes, block 212 performs normal processing in response to the re-invite message before transferring control back to decision block 206.
If the answer in decision block 211 is no, decision block 213 determines if the session that was established by the transmission of the audio question has been terminated. If the answer is no, control is transferred back to decision block 206. If the answer is yes in decision block 213, block 214 performs normal processing before transferring control back to decision block 202.
Returning to decision block 202, if the answer in decision block 202 is no, control is transferred decision block 301. The latter decision block determines if an audio question has been received in an invite message. If the answer is no, control is returned to decision block 202 of FIG. 2. If the answer is yes in decision block 301, control is transferred to decision block 303.
Decision block 303 determines if the user wants to respond and if the audio question is coming from the proper group. The user may indicate they want to respond to the audio question by a keystroke or voice command. Also, the user may predefine that the audio question is to be refused when the user is actively engaged in a voice call. Further, the user can define situations under which no response will be given to the audio question using a software agent executing rules predefined by the user or by presence rules entered into a presence server such as presence server 107. If the answer is no in decision block 303, control is transferred to decision block 307.
If the answer is yes in decision block 303, block 304 records a message and block 306 forms and transmits an invite message with the recorded message before returning control to decision block 302.
If the answer is no in either decision block 302 or 303, decision block 307 determines if the session has been terminated. If the answer is yes, block 308 processes this normally before returning control back to decision block 202 of FIG. 2.
If the answer in decision block 307 is yes, block 309 determines if the user of the terminal wishes to change the session to an RTP stream so as to establish a voice conference call. If the answer is yes, block 311 forms and transmits a re-invite message for a RTP stream before returning control back to decision block 302.
If the answer in decision block 309 is no, decision block 312 determines whether a re-invite message has been received to establish a RTP stream. If the answer is yes, block 313 performs normal processing before transferring control back to decision block 302. If the answer in decision block 312 is no, control is transferred back to decision block 302.
