Abstract

Provided is a method and system for requesting and granting a media transmission right of a PoC user. The method includes a PoC client transmitting an MBCP Request message to a PoC server, the PoC server receiving the MBCP Request message, determining whether a current state corresponds to a media transmission denial condition, and if it is determined that the current state corresponds to a media transmission denial condition, transmitting an MBCP Deny message containing at least one of time information of a media transmission timer and time information of a retry-after timer to the PoC client, and the PoC client receiving the MBCP Deny message, activating the media transmission timer and the retry-after timer using the respective time information, and re-transmitting the MBCP Request message to the PoC server if one of the media transmission timer and the retry-after timer, the retry-after timer having a longer time value, expires.

Claims15

Dependent claims

A method of requesting and granting a media transmission right of a PTT over Cellular (PoC) user in a PoC system, which includes a PoC client and a PoC server, the method comprising:

the PoC client transmitting a media transmission right request (Media Burst Control Protocol (MBCP) Request) message to the PoC server according to a request of the PoC user;
the PoC server receiving the MBCP Request message, determining whether a current state corresponds to a media transmission denial condition, and if it is determined that the current state corresponds to a media transmission denial condition, transmitting a media transmission right request denial (MBCP Deny) message containing at least one of time information of a media transmission timer and time information of a retry-after timer to the PoC client;
and
the PoC client receiving the MBCP Deny message, if the time information of the media transmission timer and the time information of the retry-after timer are contained in the MBCP Deny message, activating the media transmission timer and the retry-after timer using respective time information, and re-transmitting the MBCP Request message to the PoC server if one of the media transmission timer and the retry-after timer, the retry-after timer having a longer time value, expires.

1 more element

A system for requesting and granting a media transmission right of a PTT over Cellular (PoC) user, the system comprising:

a PoC client for transmitting a media transmission right request (MBCP Request) message according to a request of the PoC user, and if a media transmission right request denial (MBCP Deny) message is received, determining whether time information of a media transmission timer and time information of a retry-after timer are contained in the MBCP Deny message, and if the time information of the media transmission timer and the time information of the retry-after timer are contained in the MBCP Deny message, activating the media transmission timer and the retry-after timer using respective time information, and if one of the media transmission timer and the retry-after timer, which has a longer time value, expires, re-transmitting the MBCP Request message;
and
a PoC server for, if the MBCP Request message is received, determining whether a current state corresponds to a media transmission denial condition, and if it is determined that the current state corresponds to a media transmission denial condition, transmitting the MBCP Deny message containing at least one of the media transmission timer time information and the retry-after timer time information to the PoC client.
