  • Patent number: 8780938
    Abstract: A technique for performing layer 2 processing is described. In a method implementation of this technique, at least one first RLC SDU is created from one or more first RLC PDUs. It is assumed here that the first RLC SDU belongs to an incomplete RLC SDU set that is to comprise at least one second RLC SDU, and that the second RLC SDU is to be created from at least one second RLC PDU not yet available. In a next step, a first PDCP function is applied to the first RLC SDU to create a data packet. The RLC function is only performed after the second RLC PDU has become available (or after an RLC time-out). Then, after the RLC function has been performed, the data packet is released to a second PDCP function.

  • Patent number: 8670758
    Abstract: A technique for inter-platform communication between functional components located on different network access platforms will be described. A method aspect of this technique comprises the step of providing a first network access platform comprising a first functional component adapted to provide and/or request a platform-based function to and/or from a second functional component located on a second network access platform. On the first network access platform an inter-platform communication application is installed that is adapted to control signalling between the first functional component and the second functional component. The inter-platform communication application is enabled to contact a first middleware function provided for accessing the second functional component. Then, a communication path is established between the first functional component and the second functional via the inter-platform communication application and the first middleware function.

  • Patent number: 8543158
    Abstract: A technique for selectively providing network access to various components is described. A modem device for realizing this technique comprises a first platform module adapted to support network access via a Radio Access Technology (RAT). The first platform module comprises a first data interface. The apparatus further comprises a second data interface adapted to be coupled to a second platform and a third data interface adapted to be coupled to an external device. A switching mechanism selectively couples the first data interface to the second data interface to provide network access, via the second platform module, to an application residing on the apparatus. The switching mechanism may further couple the first data interface to the third data interface to provide network access to the external device.

  • Patent number: 8483061
    Abstract: A distributed memory architecture for a layer 2 processing circuit chip (50) is described. In one implementation, the layer 2 processing circuit chip (50) comprises an external memory interface configured to provide access to data packets stored in an external memory (52), a layer 2 processor (54) coupled to the external memory interface (56) and configured to process data packets retrieved from the external memory (56) to generate RLC SDUs, and an on-chip memory (58) coupled to the layer 2 processor (54) and configured to store the RLC PDUs generated by the layer 2 processor (54) prior to their transmission. Upon a request to retransmit an RLC PDU, the layer 2 processor (54) is configured to selectively read the RLC PDU to be retransmitted from the on-chip memory (58) or a data packet comprising the RLC PDU to be retransmitted from the external memory (52).

  • Patent number: 8170001
    Abstract: A technique for synchronizing different network access modules in a mobile communication device is provided. A device embodiment (100) comprises a first network access module (102) having a first radio technology, or RAT, interface (114) and being clocked at a first clock frequency and a second network access module (104) having a second RAT interface (130) and being clocked at a second clock frequency, wherein the first clock frequency is different from the second clock frequency. A method implementation of this technique comprises the steps of generating a clock signal having the first clock frequency, outputting the clock signal for use as a first reference clock signal in the first network access module (102), converting the clock signal to the second clock frequency, and outputting the converted clock signal for is use a second reference clock signal in the second network access module (104).

  • Publication number: 20100316021
    Abstract: A technique for transferring data between an application and at least two Radio Access Technology (RAT) modules selectively connectable to a network is described. A device embodiment of this technique comprises a storage adapted to hold data from the application, the data being intended to be transmitted via at least one of the RAT modules. Furthermore, the device comprises a first control mechanism adapted to initiate holding of the data in the storage when the RAT modules assume the same connection state. The connection state is selected from a connected state in which data transmission via the respective RAT is enabled and a disconnected state in which data transmission via the respective RAT is disabled. The device also comprises a second control mechanism adapted to initiate sending of the data held in the storage to the RAT module assuming the connected state when the RAT modules assumed different connection states again.
