Patent ID: 8364192

Claim:
A method comprising: a radio access network (RAN) component receiving an instant communication session setup message via a packet-switched network, wherein the instant communication session setup message contains a quality of service (QOS) indication and seeks to establish an instant communication session with a wireless communication device (WCD) served by the RAN component; in response to receiving the instant communication session setup message, the RAN component transmitting a page request message to the WCD, and determining that (i) the QOS indication contains a pre-determined QOS value, and (ii) the WCD is capable of supporting the instant communication session; and in response to determining that (i) the QOS indication contains the pre-determined QOS value, and (ii) the WCD is capable of supporting the instant communication session, the RAN component pre-allocating at least one QOS resource for the instant communication session before receiving a connection request message from WCD, wherein the connection request message is a reply to the page request message.
