20140126448 | ENERGY AWARENESS IN MOBILE COMMUNICATION USER EQUIPMENT AND NETWORKS, INCLUDING OPTIMIZATIONS BASED ON STATE COMPRESSION - A mobile communication system includes a core network having one or more elements that handle bearer processing and/or that store user equipment context information for at least one user equipment or device. Elements of the core network are configured to suspend some or all bearer processing and/or to compress portions of or the whole user equipment context information for the at least one user equipment or device. Elements of the core network may also be configured to transfer portions or all of the user equipment context information to other elements of the core network and/or to remove portions or all of the user equipment context information. Suspending some or all bearer processing and/or compressing portions of or the whole user equipment context information may be done for a user equipment or device in an energy saving state. Related methods and a user equipment device are also described. | 05-08-2014 |
20140169332 | METHOD FOR SUPPORTING SELECTION OF PDN CONNECTIONS FOR A MOBILE TERMINAL AND MOBILE TERMINAL - A method for supporting selection of PDN connections for a mobile terminal, in particular in decentralized mobile operator networks, wherein the mobile terminal is connected to an access point, wherein the mobile terminal is in active mode having at least one ongoing IP session to a Packet Data Network (PDN) via a PDN gateway-first PDN gateway-, wherein monitoring whether a more suitable PDN gateway-second PDN gateway-than the first PDN gateway becomes available for the mobile terminal is performed, and wherein in case of detecting the second PDN gateway, any new IP session of the mobile terminal to the PDN is established by initiating a new PDN connection to the second PDN gateway, while an already ongoing session associated with the existing PDN connection to the first PDN gateway is kept. Furthermore, a mobile terminal with PDN connection selection support is disclosed. | 06-19-2014 |
20140233390 | METHOD AND SYSTEM FOR CONGESTION AVOIDANCE IN MOBILE COMMUNICATION NETWORKS - In a method for congestion avoidance in mobile communication networks, the mobile communication network includes a sender and a receiver, one located in a mobile network, the mobile network being connected to a network of the mobile communication network. Steps include: detecting congestion in a first communication plane of the mobile communication network between the sender and the receiver; b) providing a congestion notification further downstream in the direction of a data transmission path between the sender and the receiver; c) providing congestion notification information on the opposite data transmission path on a second communication plane of the mobile communication network; and d) initiating congestion avoidance. The congestion notification and congestion notification information are transmitted between mobile network entities. The data transmission path and the opposite data transmission path are on the same communication plane. | 08-21-2014 |
