Definitions

  • H.324 to indicate H.324- like equipment including H.324M and 3G-324M equipment and "H.323" to indicate H.323-like equipment.
  • H.223 Multiplexing protocol for low bit rate multimedia communication.
  • H.223 specifies a frame-oriented multiplexing protocol which allows the transfer of any combination of digital voice, video and data (e.g. command and control) information over a single communication link.
  • the H.223 may have a number of modes of operation, specified in Annexes A, B and C of the H.223 Recommendation that are intended to provide increased resilience in the presence of errors. These are also known as Mobile Levels 1, 2 and 3.
  • H.223 without the application of any of these Annexes is also sometimes referred to as operating at Mobile Level 0 (base-line).
  • H.245 PDU SRP/NSRP
  • H.245 PDU SRP/NSRP
  • the H.245 messages have to be concatenated in a way as not to violate dependencies.
  • the usage of H.245 within H.324 allows equipment to concatenate multiple
  • Type II Speed-up using H.245 Non-Standard Messages
  • H.245 allows a number of ways of adding non-standard extensions. There are a number of ways to add non-standard messages in H.245 in order to speed up the call. The most interesting of these is the use of a nonstandard Capability within the H.245 TerminalCapabilitySet message and a NonStandardMessage H.245 Response message.
  • the computer-readable medium includes one or more instructions for transmitting the one or more custom Non-Standard H.245 messages or custom Non- Standard fields in standard messages from the first terminal to the second terminal, one or more instructions for transmitting a custom Non-Standard response message associated with the one or more custom Non-Standard H.245 messages or custom Non-Standard fields from the second terminal to the first terminal, and one or more instructions for processing the one or more custom H.245 messages or custom Non-Standard fields during a predetermined time period.
  • the computer-readable medium includes one or more instructions for establishing the initial predetermined mode of operation between the first terminal and the second terminal through the bearer channel based upon at least one or more of the custom H.245 messages or custom Non-Standard fields.
  • FIG. 5 illustrates an embodiment of the method of using bearer "user" information to reduce connection times for calls between an H.324 terminal and an H.323 terminal using a gateway;
  • FIG. 6 illustrates an embodiment of the ASN.l Syntax description for Type II Request
  • the invention provides methods for reducing the time required to establish calls between terminals that implement the ITU-T H.324 Recommendation and other Standards and Recommendations derived from or related to this such as the 3G-324M recommendation developed and adopted by the Third Generation Partnership Projects (3GPP and 3GPP2).
  • the invention has been applied to the establishment of multimedia telecommunication between 3G-324M (H.324M based protocol) multimedia handsets on a mobile telecommunications network, and between 3G-324M multimedia handsets and H.323 based terminals on a packet network using a Multimedia Gateway to mediate between the protocols used at each endpoint, but it would be recognized that the invention may also include other applications.
  • 3G-324M H.324M based protocol
  • multimedia handsets and H.323 based terminals on a packet network using a Multimedia Gateway to mediate between the protocols used at each endpoint
  • a terminal combines H.245 Request Terminal Capabilities (TCS) and Request Master Slave Determination (MSD) messages into a single H.245 PDU. It also concatenates TCS and MSD Response Messages (Acks), multiple Open Logical Channel Requests (OLC) and Multiplex Table Entry Send Request (MES) in a single H.245 PDU. Finally it combines OLC and MES responses into a third H.245 PDU.
  • TCS Request Terminal Capabilities
