  • Patent number: 9578634
    Abstract: An approach for reducing power consumption during data transfer is provided. A period of delayed release of one or more radio resources associated with a data flow is detected. In response to the detection, radio resource reduction information is generated for a data transfer during the period, wherein the radio resource reduction information specifies a reduced allocation of one or more radio resources. Control information is generated for transmission to a mobile station, wherein the control information specifies the radio resource reduction information.

  • Publication number: 20140198639
    Abstract: A mobile station detects whether there is congestion in a cell by monitoring a first channel fix downlink messages and decoding the messages to see if the decoded messages indicate congestion, where the first channel is a common control channel (CCCH). For the case in which the mobile station determines from the decoded messages that there is no congestion, the mobile station initiates a random access procedure by transmitting a request message uplink on a random access channel (RACH). Else for the case in which the mobile station determines from the decoded messages that there is congestion, the mobile station waits for a waiting time before initiating a random access procedure.

  • Patent number: 8687538
    Abstract: There is provided arrangements for controlling and supporting network sharing. A set of common system information which applies to communication networks sharing at least one shared local communication area for communicating with host network elements is prepared. A set of dedicated system information which applies to at least one of the communication networks sharing the at least one shared local communication area is prepared. The dedicated system information is addressed only to host network elements being configured to support sharing of a local communication area.

  • Patent number: 8483133
    Abstract: An approach is provided for providing a reliable transmission of data associated with different traffic types over a common communication session. A temporary block is established between an apparatus and another apparatus. The apparatus multiplexes Radio Link Control (RLC) acknowledged mode data and at least one of RLC unacknowledged mode data and RLC non-persistent mode data. The apparatus then determines to transmit the multiplexed data in the temporary block flow to the other apparatus.

  • Publication number: 20130148618
    Abstract: A method, apparatus and computer program product are provided in order to allow for greater multiplexing of a resource on a transmission medium. The method may provide for transmission of a flag which indicates to a subset of mobile terminals that a resource, such as an uplink packet data channel, on a transmission medium that is shared by the subset will be allocated to a respective one of the subset. The method may also provide for transmission of an identity of a respective one of the subset and may then receive communications from the respective one of the subset utilizing the resource on a transmission medium.

  • Publication number: 20130100802
    Abstract: Embodiments of the invention provide apparatus, a method and a computer readable product for avoiding traffic congestion in a mobile communication system. In an exemplary embodiment there is provided an apparatus, including at least one controller and a memory storing a computer program which are arranged to receive and read a series of blocks on a first channel, to determine whether there is congestion on the basis of said series of blocks, and, in the event that the determination is that there is no congestion, to transmit a channel request on a second channel.

  • Publication number: 20080019310
    Abstract: The exemplary embodiments of this invention provide apparatus, methods and computer program products that enable a transmitter to preemptively re-transmit data blocks (e.g., RLC/MAC blocks) without relying on acknowledgment information from the receiver. In one exemplary, non-limiting embodiment, a method includes: determining whether at least one criterion is fulfilled; transmitting a data block to a receiver; and in response to determining that the at least one criterion is met, preemptively re-transmitting the data block to the receiver. In further exemplary embodiments, preemptively re-transmitting the data block involves using one of a consecutive re-transmission scheme or a parallel re-transmission scheme.
