  • Patent number: 9894556
    Abstract: Methods, systems and apparatus for managing and/or enforcing one or more policies for managing internet protocol (“IP”) traffic among multiple accesses of a network in accordance with a policy for managing bandwidth among the multiple accesses are disclosed. Among the methods, systems and apparatus is a method that may include obtaining performance metrics associated with the multiple accesses. The method may also include adapting one or more rules of one or more the policies for managing IP traffic among the plurality of accesses based, at least in part, on the performance metrics and the policy for managing bandwidth among the plurality of accesses. The method may further include managing IP traffic associated with at least one wireless transmit and/or receive unit (“WTRU”) among the plurality of accesses responsive to the adapted rules.

  • Publication number: 20160183324
    Abstract: Systems, apparatuses and methods for bandwidth management, aggregation and internet protocol (“IP”) flow mobility (“IFOM”) across multiple-access technologies are provided. Included is a method that includes selecting, from a packet data network (“PDN”) connection formed through a plurality of access systems communicatively coupled with a wireless transmit and/or receive unit (“WTRU”), an access system over which to transport a flow of internet protocol (“IP”) traffic to and/or from the WTRU. The method may also include sending, to the WTRU, a request to associate the flow of IP traffic with the selected access system.

  • Publication number: 20120079559
    Abstract: Systems, methods, and apparatus are disclosed for coordinating enforcement of policies on a network and/or a wireless transmit/receive unit. The policies may include stakeholder-specific policies of one or more stakeholders that provide services on a user equipment. Enforcement of the stakeholder-specific policies may be securely coordinated using a policy coordination function. Systems, methods, and apparatus are also disclosed that include a network policy coordination function (NPCF) that coordinates service control policies and access control policies. The NPCF may coordinate enforcement of the service control policies for one or more service control entities and the access control policies for one or more access control entities.

  • Publication number: 20110188449
    Abstract: A method and apparatus for performing session duplication are provided. A communication session between a first wireless transmit/receive unit (WTRU) and a remote device may be duplicated to add a second WTRU to the communication session without disruption of the communication session on the first WTRU or the remote device. The communication session may be duplicated by a network unit in response to a policy or a communication session duplication request. The first WTRU or the second WTRU may initiate session duplication by transmitting a communication session duplication request. Session duplication may include duplication of one or more media flows associated with the communication session. Session duplication may include transferring or sharing control of the communication session.

  • Patent number: 6144647
    Abstract: A communication system, a mobile services switching center and a method is described, for allowing a multi-dialogue communication to take place between a first subscriber station (MS1, MS2, . . . MSn) and a second subscriber station (ISDN ST1) through a mobile services switching center (MSC/VLR) of a public land mobile network (PLMN). A mapping device (MP) of the mobile services switching center (MSC) maps several communication channels between the first subscriber station (MS1, MS2, . . . MSn) and the mobile services switching center (MSC/VLR) onto at least one second communication channel (CC2) between the PLMN and a fixed network (FN).

  • Patent number: 5940759
    Abstract: The invention relates to a setting-up of calls of different types between a subscriber and a mobile subscriber of a mobile radio communication network. The subscriber can initiate calls of different types by specifying compatibility information in the call set-up request and a home location register (HLR) in the mobile radio communication network (PLMN) obtains all attributes of the mobile bearer capability needed for any specific type of call in the PLMN, even if the compatibility information is filtered due to the transfer of the call set-up request through the network protocols. Instead of having to remember a plurality of numbers for a plurality of different types of calls, the subscriber may only use one single number and the compatibility information to specify the entire requirements of bearer capabilities necessary to support the call in the PLMN.
