Communications protocol

An communication protocol, said protocol enabling a plurality of communication functions between one or more end user devices and a network connected subscriber server system, said subscriber server system comprising one or more servers, said one or more servers located locally or distributed across said network, said protocol comprising:

• a. a set of generic verb header fields;
• b. a plurality of transaction verbs, said transaction verbs comprising specific fields appended to at least one generic verb header field from said set of generic header fields;
• c. a first grouping of transaction verbs, said first grouping providing end user device presence information to said subscriber server system;
• d. a second grouping of transaction verbs, said second grouping providing call functions between said end user device and one or more remote devices through said subscriber server system;
• e. a third grouping of transaction verbs, said third grouping providing messaging functions between said end user device and one or more remote devices through said subscriber server system;
• f. a fourth grouping of transaction verbs, said fourth grouping providing address book functions between said end user device and said subscriber server system, and
• g. a fifth grouping of transaction verbs, said fifth grouping providing policy functions between said end user device and said subscriber server system.

A communications system including a protocol providing communication functions over a network, one or more of the elements of said system implemented on one or more servers located across said network, said communications system comprising:

• one or more subscriber servers;
• a plurality of clients, said clients operatively connected to at least one of said one or more subscriber servers over said network;
• a transport protocol operative across said network;
• a transaction based verb protocol overlaid on said transport protocol;
• said transaction based verb protocol grouped into multiple verb families;
• said multiple verb families comprising at least two of the group:
• presence, policy, calling, messages, and address book.

A communication method providing communication functions over an communication network, one or more steps of said method implemented on one or more servers located across said network, said communications method comprising:

• overlaying a communications protocol comprising a plurality of transaction verbs on a transport;
• operatively connecting one or more clients to one or more subscriber servers, said clients operatively connected to at least one of said one or more subscriber servers over said network using said communications protocol;
• selecting a series of correlating transaction based verbs from said communications protocol based on a desired communication function;
• said transaction based verbs grouped into multiple verb families based on said desired communication function, and
• said multiple verb families comprising at least two of the group:
• presence, policy, calling, messages, and address book.

A communication protocol, said protocol enabling a plurality of communication services across a network, said protocol comprising:

• a. a plurality of first communication function transactional verbs, said plurality of first communication function transactional verbs comprising requests for communication services, said first verbs each comprising a generic verb header and one or more parameters for specified transactions;
• b. a plurality of second communication function transactional verbs comprising responses to said first communication function transactional verbs, said responses comprising a combination of said first communication function transactional verbs and any of:
• verb wait, verb accept, verb redirect or verb reject, and one or more parameters for specified transactions;
• c. said first and second communication function transactional verbs operative to provide multiple transaction groupings, said groupings providing said communication services between a requestor and responder, and
• d. said multiple transaction groupings comprising two or more of:
• presence, policy, calling functions, address book or messaging functions.
