Abstract: In a wireless communications network, a method of performing a location service with respect to a mobile station includes communicating a paging message containing an indication of whether the paging message is related to at least one of an emergency-related location service and a law enforcement-related location service. In another aspect, a mobile station in a wireless communications network communicates messaging to move the mobile station to a traffic channel in response to a callback by at least one of an emergency services entity and a law enforcement entity. The mobile station also receives a location request on the traffic channel, the location request containing an indication of whether the location request is related to at least one of an emergency-related location service and a law enforcement-related location service.

Abstract: Systems and methods for dynamic congestion management in communications networks are disclosed herein. According to an aspect, a method can include determining traffic statistics of at least one node in a communications network. The method can also include determining whether the at least one node is congested based on the traffic statistics. Further, the method can include dynamically changing or provisioning a set of at least one traffic shaping rule for application to the at least one node in response to determining that the at least one node is congested.

Abstract: Methods, systems, and computer readable media for DPI-enabled traffic shaping for xDSL networks are disclosed. According to one method, a DPI node analyzes signaling for an xDSL network access node or a broadband network gateway to determine nodal or link capacities available to nodes upstream from the network access node or the broadband network gateway for delivering downstream traffic to the network access device. The DPI node uses the determined capacities to shape downstream traffic delivered to the network access device.

Abstract: System and method for enabling push-to-talk (PTT) private calls in a wireless communications network are described. One embodiment includes selecting a called party private identification for a private call by a calling party on a mobile device; pressing a PTT button on the mobile device; transmitting a SIP SUBSCRIBE including the calling and called parties private identifications to request a speech token; redirecting the SIP SUBSCRIBE to the PTT Server for purposes of removing the calling party and the called party from a multicast group; receiving an acknowledge message that includes a speech token; transmitting calling party information from the PTT Server to the called party; communicating speech packets from the calling party to the called party in a half-duplex manner; releasing the PTT button on the mobile device; transmitting a SIP SUBSCRIBE to release the speech token; and notifying the calling and called parties that the group's speech token is available.
