Definitions

  • FIG. 2 illustrates how several applications interact with each other
  • the regional deployments may be distributed across the service provider's network to ensure the network delays associated with call setup are kept at a minimum, for the purpose of satisfying instant-response requirement. Distributing the call load across several regionalized systems also ensures that adequate scalability schemes can be developed to support large number of users.
  • the regionalized application server components provide user registration, intra-regional call setup and management, and alert initiation and delivery for the users, which are registered in the region.
  • MCH media control unit
  • MCU media control unit
  • the MCH may host and manage multiple MCU processes. Each MCU may handle the real-time signaling and media processing for a single call.
  • the functions the MCU performs for a call may include: • Handling call assignments from RD 114 020195
  • the regional dispatcher may assign the call to an MCU located in the same region as the regional dispatcher, if there are MCU resources available in that region.
  • the resulting call using this type of call setup is referred to as a "locally-hosted" call, or local call.
  • the regional dispatcher may have a choice to assign the call to an MCU within the same region or in a remote or foreign region. The regional dispatcher may make this decision based on the users' location information to find the optimal path of travel for the IP packets containing media and signaling. If a majority of the users are located in a particular region, the call may be assigned to that region.
  • the call-setup and call-control signaling is performed according to SIP semantics.
  • SIP may be transported using either the well- known user datagram protocol (UDP) or transmission control protocol (TCP)
  • each CD performs SIP based signaling functions using UDP.
  • each CM may expect to receive SIP signaling requests via UDP.
  • Real-time signaling may occur via dynamic UDP/IP interface on the CM and each CD.
  • Other signaling may take place via a fixed TCP/IP interface between the CM and the CD using the SIP, for example.
  • PTT requests While the packet data service is active for all users, PTT requests, which may be
  • the MCU may send wakeup triggers 414 directed to target listeners.
  • the MCU may determine whether a packet-data session exists for the target mobile, and forwards the trigger packet to the appropriate infrastructure element, e.g., a base station.
  • the infrastructure may page each individual target MS to start re-establishing its dedicated traffic channel.
  • the target MS may then start re-establishing its dedicated traffic channel, e.g., by performing the "service option 33 re-origination," for example.
  • the target MS may also start radio link protocol (RLP) synchronization.
  • RLP radio link protocol
  • the target MSs may re-establish their dedicated traffic channels and synchronize their RLPs advantageously in parallel with same functions being performed by the client MS.
  • the talker MS may rely on the RD-generated floor-control response to trigger its traffic channel re-activation, in the same fashion that the wakeup requests sent by the MCU trigger traffic channel re-activation for the listener mobiles.
  • the race condition is avoided as the potential for simultaneous mobile-initiated service origination and network-initiated paging of the mobile is avoided.
  • the user may be allowed to start talking after the user has requested floor control, by buffering the media before dedicated channels are reestablished between the client and the listeners.
  • the system allows the talker to start talking before the listeners' traffic channels have been fully re-established. This allows the talker to start talking earlier, reducing his apparent PTT latency. Since listeners don't experience PTT latency, their experience is unaffected, i.e., the PTT latency is shifted from the talker to other parts of the system.
