Abstract
A method for providing fast and flexible call setup, the method comprising establishing a plurality of phantom channels over a bearer channel, wherein at least one of the plurality of phantom channels is pre-assigned to a first session negotiation method, at least one of remaining phantom channels of the plurality of phantom channels is pre-assigned to a second session negotiation method, the second session negotiation method has at least one property different from the first session negotiation method, and at least one of the remaining phantom channels is assigned to at least one fixed media operation point, whereby the first session negotiation method is utilized for flexible session setup.
Claims20
A method comprising:
- establishing, by at least one processor, a plurality of phantom channels over a bearer channel, wherein at least one of the phantom channels comprise a media channel associated with a predetermined codec;
- pre-assigning, by the at least one processor, at least one of the plurality of phantom channels to a first session negotiation method;
- pre-assigning, by the at least one processor, at least one of remaining phantom channels of the plurality of phantom channels to a second session negotiation method, wherein the second session negotiation method has at least one property different from the first session negotiation method;
- assigning, by the at least one processor, at least one of the remaining phantom channels to at least one fixed media operation point, whereby the first session negotiation method is utilized for flexible session setup;
- and
- reverting, by the at least one processor, to the second session negotiation method, when the first session negotiation method is not available.
An apparatus comprising:
- at least one processor;
- and
- at least one memory including code, which when executed by the at least one processor provides operations comprising:
- establishing a plurality of phantom channels over a bearer channel, wherein at least one of the phantom channels comprise a media channel associated with a predetermined codec;
- pre-assigning at least one of the plurality of phantom channels to a first session negotiation method;
- pre-assigning at least one of remaining phantom channels of the plurality of phantom channels to a second session negotiation method, the second session negotiation method having at least one property different from the first session negotiation method;
- assigning at least one of the remaining phantom channels to at least one fixed media operation point, whereby the first session negotiation method is utilized for flexible session setup;
- and
- reverting to the second session negotiation method, when the first session negotiation method is not available.
An apparatus comprising:
- an establishing unit configured to establish a plurality of phantom channels over a bearer channel, wherein at least one of the phantom channels comprise a media channel associated with a predetermined codec;
- a first pre-assigning unit configured to pre-assign at least one of the plurality of phantom channels to a first session negotiation method;
- a second pre-assigning unit configured to pre-assign at least one of remaining phantom channels of the plurality of phantom channels to a second session negotiation method, the second session negotiation method having at least one property different from the first session negotiation method;
- an assigning unit configured to assign at least one of the remaining phantom channels to at least one fixed media operation point, whereby the first session negotiation method is utilized for flexible session setup;
- and
- a reverting unit configured to revert the second session negotiation method, when the first session negotiation method is not available, wherein the establishing unit, the first pre-assigning unit, the second pre-assigning unit, the assigning unit, and the reverting unit are implemented in at least one processor.
A non-transitory computer readable storage medium encoded with at least one instruction which is executed by a processor to perform at least:
- establishing a plurality of phantom channels over a bearer channel, wherein at least one of the phantom channels comprise a media channel associated with a predetermined codec;
- pre-assigning at least one of the plurality of phantom channels to a first session negotiation method;
- pre-assigning at least one of remaining phantom channels of the plurality of phantom channels to a second session negotiation method, wherein the second session negotiation method has at least one property different from the first session negotiation method;
- assigning at least one of the remaining phantom channels to at least one fixed media operation point, whereby the first session negotiation method is utilized for flexible session setup;
- and
- reverting to the second session negotiation method, when the first session negotiation method is not available.
