Abstract:

Techniques are disclosed for establishing packet-based communication between first and second endpoints over a network, in a manner which reduces the latency and complexity associated with call setup. In accordance with one aspect of the invention, a resource is requested from the network utilizing a first protocol, and while the request is pending, transmission of packets at a first priority level is commenced. After a response is received from the network granting access to the requested resource, a tagging mechanism is utilized to identify particular packets for transmission at a second priority level higher than the first priority level. In an illustrative embodiment, the first protocol is the Resource Reservation Protocol (RSVP), the first priority level corresponds to a Better than Best Effort (BBE) policy, and the second, higher priority level corresponds to an Expedited Forwarding (EF) policy. These policy levels may be implemented for a given packet by setting a Type of Service (TOS) byte in a header of the given packet to a value specifying the corresponding policy.

Abstract:

A telecommunications system is disclosed for a destination or “target” party to indicate his or her “presence” or availability to receive communications. The presence indication may include various states such as “available”, “unavailable”, “on vacation”, etc. Each time an initiating party attempts to navigate to a target party, the communications system informs the initiating party of a target party's presence status. The initiating party can then decide which menu path to choose: to continue to a covering party for the target party or the target party's coverage path, such as voicemail. In this manner, user frustration is alleviated, fewer telecommunications resources are consumed and both the initiating and target parties can communicate more effectively.
