Patent number: 12401971Abstract: A network entity controls delivery of information to user devices over bearer paths including unicast channels and multicast channels. The network entity may interoperate in any of a number of network architectures, including 3GPP Internet Protocol Multimedia Subsystem (IMS) and 3GPP2 Multimedia Domain (MMD). The network entity may provide functionality of a modified 3GPP2 Broadcast and Multicast Service (BCMCS) controller component configured to enable BCMCS signaling protocol transactions to occur over 3GPP IMS interfaces and/or 3GPP2 MMD interfaces. A network entity configured to interoperate in a 3GPP IMS and/or 3GPP2 MMD network architecture may provide network-mobile multimedia services to user devices. Content associated with the multimedia services may be stored in storage devices in the network. A common interface through which a network operator defines service-specific parameters of a number of unicast and multicast multimedia services deployed in a distribution network may be provided.Type: GrantFiled: September 8, 2022Date of Patent: August 26, 2025Assignee: ERICSSON EVDO INC.Inventors: Fabio M. Chiussi, Roshan M. Rao

Patent number: 9019935Abstract: In connection with a mobile wireless subnetwork having multiple radio network controllers and multiple radio nodes, a session established for an access terminal is associated with a serving radio network controller. The association is maintained as the access terminal moves from the coverage area of one radio node to the coverage area of another radio node within the same subnetwork. Access channel packets are routed from an access terminal having an existing session to the serving radio network controller by determining the IP address of the serving radio network controller using a session identifier.Type: GrantFiled: March 26, 2012Date of Patent: April 28, 2015Assignee: Ericsson EVDO Inc.Inventors: M. Vedat Eyuboglu, Arthur J. Barabell, Sanjay Cherian

Patent number: 8843638Abstract: A connection is established between an access terminal and a first radio network controller through a first radio node. The first radio node is controllable primarily by the first radio network controller. The connection is maintained with the first radio network controller as the access terminal moves from a coverage area of the first radio node toward a coverage area of a second radio node. The second radio node is controllable primarily by a second radio network controller and controllable subordinately by the first radio network controller. A connection is also established through the second radio node. Upon a fulfillment of a predetermined criterion, the connection is transferred from the first radio network controller to the second radio network controller.Type: GrantFiled: December 13, 2007Date of Patent: September 23, 2014Assignee: Ericsson Evdo Inc.Inventors: Deepak Garg, Gopal Harikumar, Fugui Wang

Patent number: 8639247Abstract: In addition to other aspects disclosed, a radio access network authenticates the identity of an access terminal using a session identifier and another identifier (different from the session identifier). The session identifier and the other identifier are provided by the access terminal.Type: GrantFiled: December 12, 2006Date of Patent: January 28, 2014Assignee: Ericsson Evdo Inc.Inventors: Dennis Ng, Woojune Kim, Airin D.

Patent number: 8619702Abstract: The radio node controller of one subnet sends a communication to an access terminal over a control channel through the infrastructure of another subnet. The radio node controller maintains an open traffic channel with an access terminal when the access terminal moves from a coverage area of the first subnet to a coverage area of the second subnet and when the access terminal uses a carrier in the first subnet that cannot be used in the second subnet. In a radio access network including a first and a second subnet, in which the first subnet includes both a first radio node controller and radio nodes that are configured in accordance with one 1xEV-DO standard and the second subnet includes radio nodes configured in accordance with another 1xEV-DO standard, the first radio node controller maintains an open traffic channel with an access terminal when the access terminal moves from the coverage area of the first subnet to the coverage area of the second subnet.Type: GrantFiled: December 16, 2005Date of Patent: December 31, 2013Assignee: Ericsson Evdo Inc.Inventors: Deepak Garg, Prasasth R.

Patent number: 8615238Abstract: In a radio access network, multiple radio network controllers are connected to several radio nodes using a network. The interconnected radio network controllers and radio nodes are addressable, and, therefore, each radio network controller can communicate directly with each radio node and visa versa. The radio access network can be configured to avoid active handoffs between radio network controllers by maintaining a traffic channel set up between an access terminal and a radio network controller even as the flow.Type: GrantFiled: August 16, 2010Date of Patent: December 24, 2013Assignee: Ericsson EVDO Inc.Inventors: Vedat Eyuboglu, Arthur J.
