  • Publication number: 20110103311
    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.

  • Patent number: 7904088
    Abstract: The present invention relates to identifying resources allocated in a cellular network for a mobile station for packet-switched services. A first identifier is used for identifying a mobile station, and a second identifier is used for identifying resources allocated for packet-switched services for the mobile station. When a mobile station is entering or has entered a second cell from a first cell, a value of a first type for the second identifier is determined. The first type of the second identifier is for use in both the first cell and the second cell for transmitting packet-switched data between the cellular network and the mobile station.

  • Patent number: 7889689
    Abstract: The invention relates to switching between a point-to-multipoint channel and a point-to-point channel for transmitting multicast data from a mobile communication network to a mobile station. According to a first aspect of the invention, the mobile station determines the link quality of a point-to-multipoint channel employed for the transmission and requests from the network a switch to a point-to-point channel in case the determined link quality is too low. According to a second aspect of the invention, the network estimates the link quality of a point-to-multipoint channel while using at least a point-to-point channel for the transmission of multicast data, and orders the mobile station to switch to this point-to-multipoint channel, in case the estimated link quality of the point-to-multipoint channel is sufficiently high.

  • Publication number: 20100210275
    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: 20100172323
    Abstract: A method, for example, is described in the present application. Such a method can include detecting or establishing a circuit-switched call. The method can also include establishing a voice-over-internet-protocol standby call in parallel to the circuit-switched call. The method can additionally include activating the voice-over-internet-protocol standby call to become an active voice-over-internet protocol call when a handover situation is detected. The method can further include releasing resources of the circuit-switched call when the voice-over-internet-protocol standby call becomes the active voice-over-internet protocol call.

  • Patent number: 7734049
    Abstract: The invention relates to a method for transmitting data between a GRPS/EDGE radio access network and user equipment of a mobile system, and to user equipment using the method, and to GERAN. In the method, the data to be transmitted is encrypted using an encryption algorithm at the transmitting end, the encrypted data is transmitted from the transmitting end to the receiving end, and the transmitted data is decrypted using an encryption algorithm at the receiving end. The used encryption algorithm is an encryption algorithm of the radio access network UTRAN employing the wideband code division multiple access method of the universal mobile telecommunications system, in which case the input parameters of agreed format required by the encryption algorithm are created on the basis of the operating parameters of the GPRS/EDGE radio access network GERAN.

  • Patent number: 7684357
    Abstract: A system and method for reducing idle mode power consumption for mobile stations (MS) that have joined a Multimedia Broadcast/Multicast Service (MBMS) session and are waiting for the session to start. The invention is also directed to reducing the power consumption of an MS for which an MBMS session is inactive. In alternative aspects of the invention, the power consumption of mobile stations is reduced in the absence of ongoing MBMS session activity. Reduced power consumption is achieved by eliminating the need to read notification messages from an MBMS specific notification paging group when the notification message is for a different MBMS session than the paging group that the MS has currently joined.

  • Patent number: 7643450
    Abstract: In case of both circuit-switched and a packet-switched connection handover from a source (200) to a target (510) radio access network or base station subsystem a new target ID indication message (415.1; 415.2) is sent to a core network node (422) either from a core network element (215) or from the target radio access network or base station subsystem, depending on whether there is an interface (Gs) between the core network element and the core network node. In one embodiment, in contrast to the prior art, the new target ID indication message is mandated to only identify one target base station or target radio access network.

  • Patent number: 7599664
    Abstract: A method for operating a mobile equipment (ME 10) in a wireless network (12) includes receiving from a wireless network a parameter that is indicative of a signal quality experienced by the ME, such as by determining a speed of the ME; calculating in the ME an indication of link quality, the calculation employing a filtering operation having a filter length that is a function of the determined parameter, such as speed or derivative of the speed of the ME; and reporting the calculated indication of link quality to the wireless network. The wireless network derives an indication of ME speed and transmits the speed indication to the ME using a point-to-point message.

  • Patent number: 7519384
    Abstract: A system and method for minimizing the gap in service during the reception of an MBMS session due to the reselection of a neighboring cell in which that MBMS session is not ongoing, wherein a mobile station (MS) indicates its target cell and MBMS service id (i.e., BSIC, neighboring cell index, and Temporary MBMS Group Identity (TMGI)) to a network by sending this information to the network in an RLC/MAC message, e.g., a packet downlink ACK/NACK or with a new message. If the network has resources available for allocation, the network is permitted to allocate these resources for the MBMS session indicated by the MS and send corresponding MBMS neighbor cell information to the MS upon receipt of the packet downlink ACK/NACK or the new message. When the MS receives the MBMS neighbor cell information, it will then reselect to the target cell identified by the MBMS neighbor cell information.

  • Publication number: 20090010212
    Abstract: A method and an apparatus are described for increasing the flexibility of uplink resource allocation for a mobile station (MS) (100), that is backwards compatible with earlier standards that provide only a single data flow per MS. The method includes steps of (A) associating an allocated uplink resource (an Uplink State Flag (USF)) with one or more Temporary Block Flows (TBFs) for a Packet Data Channel (PDCH), and not with a MS per se (although a given USF is associated with only a single MS); and (B) using a Temporary Flow Identity (TFI) for identifying a TBF, where a TFI may be unique to a PDCH and, if not, is unique with respect to the MS on a PDCH (and hence with respect to the USF). The result is that the MS is enabled to send any of its TBFs on allocated resources of the same PDCH. An uplink resource may be allocated to the MS dynamically using the Uplink State Flag (USF) or by using a fixed allocation. A total of n Radio Bearers are associated with a single TBF, where n?1.
