A radio access network sends, to a mobile device, information indicating a cell on a first carrier of a first type and a cell on a second carrier of a second type, and sends, to the mobile device, configuration information regarding whether the mobile device is to connect with a cell on another carrier of a new carrier type. The radio access network sends, to the mobile device, information relating to a Discontinuous Reception (DRX) configuration that is specific to a type of carrier.

Using a cell as a pathloss or timing reference

Information is communicated indicating whether a cell on a first carrier of a first type is to be used as a reference cell, wherein the reference cell is at least one selected from among a pathloss reference cell and a timing reference cell, and wherein the first carrier of the first type is part of a carrier aggregation that further includes at least a second carrier of a second, different type.

A first wireless access network node receives feedback information from a second wireless access network node that performs data offload for the first wireless access node, the feedback information identifying a user equipment (UE) and including information relating to a buffer condition of a data buffer in the second wireless access network node. In response to the feedback information, performing, by the first wireless access network node, control of the data offload that includes controlling an offload of at least one radio bearer of the UE identified by the feedback information.

Controlling data offload in response to feedback information

Methods and systems for managing Multimedia Broadcast Multicast Service (MBMS) service continuity include, with a source node in a communication system, providing an MBMS, processing an event that indicates that a User Equipment (UE) being serviced by the source node is to be transferred to one of a number of candidate nodes, receiving a congestion bit from each of the candidate nodes, and providing data to the UE that causes the UE to be serviced by a target node selected from the candidate nodes based at least in part on values of the congestion bits from each of the candidate nodes.

Maintaining MBMS continuity

A first wireless access network node receives feedback information from a second wireless access network node that performs data offload for the first wireless access node. The feedback information relates to one or more of a radio resource usage, a buffer condition, a hardware resource usage or a link quality. In response to the feedback information, the first wireless access network node performs control of the data offload.

Systems, methods, and apparatuses for energy saving in heterogeneous wireless communication networks are provided. The small cell (e.g., pico cell, relay cell, femto cell) may adjust its transmit power based on the requirement of user equipments (UEs) in the cell's coverage. The small cell may detect a UE entering its coverage with or without assistance from the macro cell. An appropriate small cell may be selected to serve the UE based on its traffic load when the UE is located in the coverage of multiple small cells. The small cell may also transmit auxiliary synchronization signals to reduce the association time for the UE.

Wireless communication in heterogeneous networks

The invention is a system and method of controlling an access of a subscriber to a network. The method includes sending an identification of the subscriber and a level of access to be provided to the subscriber from a visited network of a plurality of networks () connected to a home network (); in response to the identification of the subscriber and a level of access to be provided to the subscriber, storing a subscriber profile of the authorized of access to be provided to the subscriber; and controlling access of the subscriber to any network dependent upon a comparison of access to be provided to the subscriber and the stored subscriber profile.

System and method of controlling application level access of subscriber to a network

A method, network element and user equipment, where in one embodiment at a network element within a secondary cell for self-optimizing operation with a primary cell, the method transmitting using an initial transmit power from the network element; requesting feedback from sensors located near a location; receiving the feedback from the sensors; and adjusting a transmit power based on the received feedback.

Method and system for self-organizing networks using cooperative sensing

A first wireless access network node determines whether a first wireless equipment is potentially an interferer of wireless communication of a second wireless equipment in a domain of a second wireless access network node, where the first wireless equipment is in a domain of the first wireless access node. In response to determining that the first wireless equipment is potentially the interferer of the wireless communication of the second wireless equipment, configuration information is sent to the second wireless access network node to allow the second wireless access network node or the second wireless equipment to detect an interference from the first wireless equipment and to initiate performance of an interference mitigation procedure with respect to the interference from the first wireless equipment.

Mitigating interference from wireless equipment

A method is provided for indicating an IMS (Internet Protocol Multimedia Subsystem) emergency call back to a user equipment and an access network. The method comprises including in a message from a PSAP (Public Safety Answering Point) to the user equipment and the access network an indication that the emergency call back is from the PSAP.

System and method for indicating emergency call back to user equipment

A user equipment (UE) sends, to a wireless access network node, an indication for indicating whether a transmission component causing in-device coexistence (IDC) interference in the UE is active or inactive.

Communicating an indication relating to in-device coexistence interference

A packet data network (PDN) gateway receives a message associated with a user equipment (UE) having a PDN connection. The PDN gateway determines whether the UE is accessing a network node that has a predetermined association with the PDN gateway based on the message. In response to the determination, the PDN connection is maintained or deactivated.
