In a method and system for opportunistic delivery of less-than-best-effort application data, a WIN network identified the elements of the wireless network servicing a specified mobile client. One or more elements of the wireless network servicing the specified mobile client monitor the connection state of a mobile client and notify the WIN network of connection state changes so that a chatty application running on an external application server may be notified by the WIN network to deliver packet data when the specified mobile client is connected to the network for some other purpose or when unused network resources are available. In this way, network resource overload caused by chatty applications is reduced.

Method and system for opportunistic delivery of less-than-best-effort application data over communication networks

A method for intercepting encrypted communications exchanged between first and second computing devices in a communication network, wherein interception is performed by a third computing device in the computing network. The third computing device obtains one or more packets having a packet address associated with one of the first and second computing devices in response to at least one interception routing policy being implemented in at least one element in the communication network, such that the obtained packets may be decrypted to obtain data contained therein. The third computing device preserves the packet address of the obtained packets and forwards the obtained packets toward a packet-destination one of the first and second computing devices such that the packet-destination one of the first and second computing devices is unable to detect from the one or more packets that the one or more packets were intercepted by the third computing device.

Systems and methods are described for dynamically generating one or more group lists as a sub-group of the contact list by assigning tags to contacts in a contact list. A user may define one or more tags for contacts in the contact list to generate a tag list in addition to the contact list. The tags indicate additional attributes of the contact that cannot be included in the contact list. To dynamically generate the group list, the user enters list criteria, and the tag list is searched to identify which of the contacts in the contact list has tags that match the list criteria. The contacts having tags that match the list criteria are combined into a group list which the user may then access to initiate communication with those contacts, or store for later use.

Dynamic generation of group lists for a communication device using tags

An exemplary method is implemented in a communication system in which periodically updated data for respective end-users is stored in a notification profile at a communication infrastructure node. The updated data is based on conditions associated with each end-user's communication device and its network context, where the data is not presence status. Predetermined rules are stored at the communication infrastructure node and generate respective results based on factors such as network contextual data and corresponding values contained in the notification profile data for each end-user. An event is detected by the communication infrastructure node where the event is intended to cause communication with all the communication devices that are interested in that event. The communication infrastructure node determines an action to be taken in response to the event based on the results of the rules for data associated with the first end-user. The communication infrastructure node implements the action related to the first end-user.

Event notification control based on data about a user's communication device stored in a user notification profile

A method for provisioning a peering relationship between the multimedia networks in a telecommunications system. The method comprises registering a customer with at least one of the multimedia networks; constructing the customer's mapping and routing data (including initial filter criteria) within each of the networks; synchronizing the customer's mapping and routing data between the multimedia networks; and storing the customer's mapping and routing data in a database in each of the multimedia networks. Further, the method results in network selection using the customer's mapping and routing data.

A method and apparatus for identifying a caller who does not provide caller identification on an unanswered call. The caller is asked to record his/her name (or some other characteristic utterance). If the call is unanswered, the record is retained and can be accessed by the called party when that party requests his/her stored voice mail. Advantageously, even on unanswered calls, the identity of the caller can be presented to the called party when that called party requests stored voice mail messages, even if the calling party has private service.

Enhanced private call screening

In a system and method for providing data application-triggered call volume management, data application content is multicast to a plurality of wireless terminals, the data application content containing a voice call origination invitation. A high voice traffic warning is generated in response to the multicasting event, and resources are allocated for handling increased voice traffic in response to the high voice traffic warning.

Data application-triggered call volume management

The priority communication system provides the capability to restrict access to wireless communications services to emergency service personnel, such that their access to wireless communication services is not interruptible. This is accomplished by provisioning the cell sites of a wireless communications system to respond to at least one service priority grouping, with emergency service personnel being assigned a selected service priority by a centralized emergency services agency. The service priority coverage area and emergency service personnel assigned the service priority are defined on a dynamic basis by the centralized emergency services agency and are indicated by a priority call access code that is transmitted to the emergency service personnel. In order to ensure the proper operation of the priority communication system, the priority call access codes are maintained in secrecy to thereby enable emergency service personnel to have access to wireless communications facilities.
