Abstract: At least one device receives a call request from a calling party to a called party. The device routes the call request to an Internet Protocol Multimedia Subsystem (IMS) core when a first condition is met and bypasses the IMS core when a second condition is met.

Abstract: A method includes receiving a telephone number mapping query associated with a call. The method may also include generating routing information based on the query and forwarding the routing information to a control device. The routing information may indicate that processing associated with routing the call is to bypass a core portion of an Internet multimedia subsystem (IMS) when a calling party associated with the call does not invoke an IMS service, the called party associated with the call does not invoke an IMS service and the called party is not an IMS subscriber.

Abstract: An apparatus for storing a packet including a buffer in which packets are stored. The apparatus includes a mechanism for determining an average buffer fill of the buffer, where the average buffer fill is an average fill state of the buffer. The determining mechanism is connected to the buffer. The apparatus includes a mechanism for calculating a drop probability associated with the packet which identify is the probability the packet will be dropped from a the buffer. The apparatus includes a mechanism for generating a random number. The apparatus includes a mechanism for discarding the packet from the elements if the drop probability is greater in than the random number. A method for access control.
