This is achieved by performing some of the connection set-up steps for delay-sensitive communications sessions after successfully demodulating a smaller number of indications identifying an access terminal's desired serving resource than would be demodulated in the case of a confidence-dependent communication session prior to performing the same connection set-up steps. ## Claims ### Claim 1 A method of establishing a connection request comprising: receiving a connection request for a communication session from an access terminal, wherein said connection request identifies a set of potential serving resources; determining whether said communication session is a delay sensitive session or a confidence dependent session; sending a resource allocation to said access terminal identifying an initial subset of said set of potential serving resources; receiving at least one indication identifying a desired serving resource; sending an acknowledgment signal confirming said desired serving resource after a first number of said at least one indication is successfully demodulated for a delay sensitive session; and sending an acknowledgment signal confirming said desired serving resource after a second number of said at least one indication is successfully demodulated for a confidence dependent session, wherein said first number is less than said second number. ### Claim 2 (depends on 1) The method as claimed in claim 1, for a delay sensitive session, further comprising: continuing to evaluate said at least one indication after said first number is received, and requesting a different serving resource if said second number is not successfully received with a defined time period. ### Claim 3 (depends on 1) The method as claimed in claim 1, wherein said first number of said at least one indication is zero. ### Claim 4 (depends on 1) The method as claimed in claim 1, wherein said initial subset is the same size as said set of potential serving resources. ### Claim 5 (depends on 1) The method as claimed in claim 1, wherein said initial subset is selected according to criteria comprising at least one of: serving resource availability, serving resource processor availability, serving resource bandwidth availability, serving resource drop rate, or serving resource signal strength. ### Claim 6 (depends on 1) The method as claimed in claim 1, wherein said at least one indication is a series of indications. ### Claim 7 (depends on 1) The method as claimed in claim 1, wherein said step of determining whether said session is a delay sensitive session or a confidence dependent session is configured at said access terminal. ### Claim 8 A network node comprising: a transceiver configured to receive a connection request for a communication session from an access terminal, wherein said connection request identifies a set of potential serving resources; and a processor configured to determine whether said session is a delay sensitive session or a confidence dependent session, wherein said transceiver is further configured to: send a resource allocation to the access terminal identifying an initial subset of said set of potential serving resources; receive at least one indication identifying a desired serving resource; send an acknowledgment signal confirming said desired serving resource after a first number of said at least one indication is successfully demodulated for a delay sensitive session; and send an acknowledgment signal confirming said desired serving resource after a second number of said at least one indication is successfully demodulated for a confidence dependent session, wherein said first number is less than said second number. ### Claim 9 (depends on 8) The network node as claimed in claim 8, wherein the transceiver is further configured, for a delay sensitive session, to continue to evaluate said at least one indication after said first number is received, and to request a different serving resource if said second number is not successfully received with a defined time period. ### Claim 10 (depends on 8) The network node as claimed in claim 8, wherein said first number of said at least one indication is zero. ### Claim 11 (depends on 8) The network node as claimed in claim 8, wherein said initial subset is the same size as said set of potential serving resources. ### Claim 12 (depends on 8) The network node as claimed in claim 8, wherein said transceiver is further configured to select said initial subset according to criteria comprising at least one of: serving resource availability, serving resource processor availability, serving resource bandwidth availability, serving resource drop rate, or serving resource signal strength. ### Claim 13 (depends on 8) The network node as claimed in claim 8, wherein said at least one indication is a series of indications. ### Claim 14 (depends on 8) The network node as claimed in claim 8, wherein said access terminal is configured to determine whether said session is a delay sensitive session or a confidence dependent session.
