Abstract

The Dynamic Conference Call Dispatching (DCCD) is a mobile phone and telecommunication infrastructure feature that enables subscribers in an active push-to-talk (PTT) direct dispatch call to dynamically conference in other subscribers located in the same or different urban. The feature is applicable to Motorola Integrated Dispatch Enhanced Network (iDEN tm) mobile phones and telecommunication infrastructure.

ABSTRACT

The Dynamic Conference Call Dispatching (DCCD) is a mobile phone and telecommunication infrastructure feature that enables subscribers in an active push-to-talk (PTT) direct dispatch call to dynamically conference in other subscribers located in the same or different urban. The feature is applicable to Motorola Integrated Dispatch Enhanced Network (iDEN tm) mobile phones and telecommunication infrastructure.

PROBLEM

Motorola iDEN telecommunication structure has provided PTT feature to its millions of subscribers over the years through Nextel tm services. iDEN PTT enables its subscribers initiate a direct call to others without dialing a phone number and without an observable delay. With the recent completion of iDEN nation wide dispatching capability, an iDEN mobile phone subscriber (1) (MPS) is able to dispatch a two-way radio direct call to another iDEN MPS from coast-to-coast instantaneously, either for a private call or a group call. This capability, however, does not allow a MPS in a private call or in a group call to conference in another MPS once the call has been established. Thus, in order to conference in another MPS, the current active call must be hung up and a new group call must be re-established by the initiating MPS. The initiating MPS would be required to enter in all the private IDs for all participants to set up a new group call This action would cause an interruption to the call and an inconvenience to the MPS.

SOLUTION

In this paper, it proposes a solution to the above situation with the Dynamic Conference Call Dispatching feature. The DCCD feature enables mobile phone subscribers in an active private call or in a group call to conference in another mobile phone subscriber at the convenience of the PTT and the “*” buttons. The operation scenarios section below describes how DCCD feature should work for MPS within an urban network.

OPERATION SCENARIOS

Figure 1 illustrates scenario 1 use cases where MPS A initiates a direct dispatch call to MPS B through iDEN network. MPS A then requests MPS B to conference in MPS C since MPS A does not have MPS C’s private ID.

 

  1. MPS A enables the PTT button to initiate a dispatch call to MPS B through iDEN network.
  2. MPS B responses by pressing the PTT button
  3. A direct dispatch call session is established between MPS A and MPS B.
  4. MPS A needs to join (conference) MPS C in but does not have MPS C’s private ID.
  5. MPS B has MPS C’s private ID.
  6. MPS A asks MPS B to conference MPS C in (by voice).
  7. MPS B pushes the “*” button to initiate a DCCD action and enters in MPS C’s private ID. This action will cause the MPS B’s cell phone (mobile station) terminate the current call (free up the current MPS participants), build a new participant list with all the current participants and the new participant, and request a new group call to the iDEN network with the...
