name: TBCP
full_form: Talk Burst Control Protocol
context: for the following services: 1. PoC session participation (per time period independent of usage). 2. Talk burst sending: Amount of talk bursts sent by the participant. Amount of talk bursts shall be measured as a number of talk bursts and/or as a duration and/or volume of talk bursts. When talk burst sending is charged as a number of talk bursts, only the TBCP talk burst granted message (in response to TBCP talk burst request message) received in PoC Client should be taken into account. Note that TBCP talk burst granted message could be lost. In this case, timer T11 expires in PoC Client and it sends a TBCP talk burst request message again OMA-UP-POC: "OMA POC User Plane" [205]. Therefore, several TBCP talk burst granted message could be unsuccessfully sent and they should not be charged. To fulfil this aim, PoC Server shall meter one talk burst: - when it receives the first RTP media packet for this talk burst, or - when it receives the TBCP talk burst release message, independently
description: Talk Burst Control Protocol (TBCP) is a protocol used in Push-to-talk over Cellular (PoC) services to control and manage talk bursts. It enables the PoC Server to meter and charge for talk burst sending, taking into account successful transmission of talk bursts and handling cases where TBCP messages may be lost.
explanation: TBCP is classified as a Protocol because it defines a set of rules and procedures for communication and data exchange between components within the PoC service.
