Method and system for reducing latency when initiating real-time media sessions
First Claim
1. In a communication system in which a first station initiates communication with at least a second station and provides an initial real-time media signal for transmission to the second station, a method comprising:
- buffering the initial real-time media signal until a transmission path exists to send the initial real-time media signal along its way toward the second station; and
thereafter sending the initial real-time media signal along its way toward the second station.

Abstract
A method and system for reducing latency in establishment of a real-time communication session, such as an instant chat session for instance. The method and system provides for buffering an initial real-time media signal until a transmission path exists to send the signal along its way toward a receiving station. Upon establishment of the transmission path, the signal may then be sent along its way. Further, the method and system may provide for selectively increasing the paging frequency used for paging certain mobile stations, so as to decrease the time that it takes to establish radio-link connectivity with those mobile stations.

8. A method of initiating a push-to-talk (PTT) communication session between an initiating mobile station and at least one terminating mobile station, the method comprising:
-
the initiating mobile station receiving and buffering an initiating user'"'"'s speech signal;
the initiating mobile station working to set up an initiating communication leg with a PTT server; and
responsive to establishment of the initiating communication leg with the PTT server, the initiating mobile station sending initiating user'"'"'s speech signal along to the PTT server for transmission in turn to the at least one terminating mobile station. - View Dependent Claims (9, 10, 11)

12. A method of reducing call setup latency in a push-to-talk (PTT) communication system, the method comprising:
-
an initiating mobile station receiving a user'"'"'s instruction to initiate a PTT session, and the initiating mobile station then receiving and buffering a speech signal provided by the user;
the initiating mobile station sending a SIP INVITE to a PTT server in an effort to set up an initiating RTP leg between the initiating mobile station and the PTT server;
responsive to establishment of the initiating RTP leg between the initiating mobile station and the PTT server, the initiating mobile station sending the speech signal to the PTT server for transmission in turn to at least one terminating mobile station. - View Dependent Claims (13, 15)

14. A method of reducing call setup latency in a push-to-talk (PTT) communication system, the method comprising:
-
a PTT server receiving and buffering an initiating user'"'"'s speech signal;
the PTT server working to establish a transmission path to send the user'"'"'s speech signal along to a terminating mobile station;
responsive to establishment of the transmission path, the PTT server sending the user'"'"'s speech signal along to the terminating mobile station.

16. A communication station comprising:
-
a processor;
data storage;
machine language instructions stored in the data storage and executable by the processor to carry out functions comprising;
receiving a user'"'"'s instruction to invoke a real-time media communication session with another user;
receiving a real-time media signal from the user, and buffering the real-time media signal until a transmission path exists to send the real-time media signal along its way toward the other user;
responsive to establishment of the transmission path, sending the real-time media signal along its way toward the other user.

17. A push-to-talk communication server comprising:
-
a processor;
data storage;
machine language instructions stored in the data storage and executable by the processor to carry out functions comprising;
receiving and buffering a real-time media signal from an initiating mobile station;
establishing an RTP communication leg with a terminating mobile station; and
responsive to establishment of the RTP leg with the terminating mobile station, sending the buffered real-time media signal along its way toward the terminating mobile station.
