Prioritized call sessions
First Claim
Patent Images
1. A method comprising:
- receiving a request for a prioritized call session;
determining, responsive to the request and while at least a first call session identifier is available for use by a call-handling computing device, that a second call session identifier and a third call session identifier are in use, wherein the second call session identifier and the third call session identifier are associated with prioritized call sessions; and
responsive to determining that the second call session identifier and the third call session identifier are in use;
dropping, by the call-handling computing device, a pre-existing call session that uses the second call session identifier, andrequesting, by the call-handling computing device, that the prioritized call session be initiated using the second call session identifier.

Abstract
A local network call handling device is configured to establish multiple concurrent call sessions between local network end devices and an external network. When a prioritized end device attempts to establish a call session, the call handling device may initially determine if a first call session identifier is available. If so, the call session can be established using that first identifier. If the first identifier is in use for a call session of another end device, the call handling device may either use a different call session identifier for the prioritized end device session or may drop a pre-existing call session to free an identifier for use in connection with the prioritized end device.

8. A method comprising:
-
establishing, by a call handling computing device and using a first call session identifier, a call session; receiving, during the call session, a request for a prioritized call session; responsive to the request, determining which of a first plurality of call session identifiers associated with prioritized call sessions are in use; and responsive to determining that all of the first plurality of call session identifiers are in use, and while at least a second call session identifier, not of the first plurality of call session identifiers, is available for use by the call handling computing device; dropping the call session, and requesting, by the call handling computing device, that the prioritized call session be initiated using the first call session identifier. - View Dependent Claims (9, 10, 11, 12)

13. A non-transitory computer-readable medium having stored thereon a plurality of computer-executable instructions which, when executed by a processor, cause the processor to:
-
receive a request for a prioritized call session; determine, responsive to the request and while at least a first call session identifier is available for use, that a second call session identifier and a third call session identifier are in use, wherein the second call session identifier and the third call session identifier are associated with prioritized call sessions; responsive to determining that the second call session identifier and the third call session identifier are in use, drop a pre-existing call session that uses the second call session identifier; and request that the prioritized call session be initiated using the second call session identifier. - View Dependent Claims (14, 15, 16, 17, 18, 19)
