This section would introduce the 3GPP TS 24.084 standard, which specifies the radio interface procedures for the normal operation and invocation of within 3GPP mobile systems. The core goal of this protocol is to allow a served mobile subscriber to have a simultaneous communication with more than one remote party. 2. Technical Scope and Evolution
Technical Protocols for MultiParty (MPTY) Supplementary Services: An Analysis of ETSI TS 124 084 1. Introduction
Procedures for placing the entire MultiParty call on hold using specific transaction identifiers (TI). 124084
The protocol mandates specific timers to prevent network hanging; if a response to a hold request is not received before the timer expires, the mobile station must assume failure and inform the user.
How a subscriber merges an active call and a held call into one conference session. This section would introduce the 3GPP TS 24
Part of the Layer 3 radio interface specifications.
The "SplitMPTY" operation, which allows a user to separate one party from the group for a private conversation while keeping the others on hold. 4. Error Handling and Timers How a subscriber merges an active call and
The standard has evolved significantly through different "Releases" (e.g., Release 13, 16, 18, and 19), with the most recent updates ensuring compatibility with modern network architectures.
