Abstract: The invention includes a method and apparatus for providing SIP message prioritization between network elements along at least a portion of an end-to-end path between a SIP client and a SIP server. The method includes determining a SIP message prioritization policy and distributing the SIP message prioritization policy toward a prioritizing network element adapted to assign message priority levels to respective received SIP messages using the SIP message prioritization policy, process the received SIP messages according to the respective assigned message priority levels, and transmit the prioritized SIP messages toward at least one network element in a manner for propagating the respective assigned message priority levels to the at least one network element. The prioritizing network elements include SIP network elements and non-SIP network elements.

Abstract: Location-based services are provided in a communication system comprising a wireless network. In one aspect, information indicative of location of a given mobile user device of the system is periodically collected. The collected location information is processed in a server or other processing device of the system to determine at least one normal pattern of movement of the mobile user device from at least a first location to a second location. An alert is generated if subsequent movement of the mobile user device from the first location to the second location exhibits a significant deviation from the normal pattern of movement. The normal pattern of movement may be used to generate a multidimensional geofence that includes, in addition to a geographic area dimension, at least one additional dimension such as, for example, a speed of movement dimension, a direction of movement dimension, a stop duration dimension, or a related device proximity dimension.

Abstract: In the method of handling overlapping notification requests in a network with an open application programming interface, a response is received from a server to a notification request sent to the server based on a notification request entry in a plist. The notification request requests access to at least one object. Then, notification request entries in an rlist associated with the notification entry in the plist are identified, and the response is sent to an application associated with one of the identified notification request entries in the rlist. When a new notification request is received from an application, the new notification request is added to the rlist, and at least one of the plist and links between the notification request entries in the rlist and plist are altered. When a disable request requesting that a notification request be disabled is received from an application, at least one of the plist and links between the notification request entries in the plist and the rlist are altered.
