  • Patent number: 8867511
    Abstract: A method, apparatus, and computer program product can provide for procedures at an access terminal for handling the delivery of packets from the MAC entity to the RLC entity, with an aim to reduce the occurrence of RLC resets that might otherwise be caused by out-of-order processing of control packets following a serving cell change. In one example, a MAC entity may insert an identifier into a packet delivered up to the RLC entity, to indicate whether the packet arrived from the current primary serving cell. In another example, a serving cell change procedure may include steps to flush a queue at the MAC entity and kill any running reordering release timers. In these ways potential problems caused by out-of-order control packets can be reduced or avoided.

  • Publication number: 20130250853
    Abstract: The present description provides methods and apparatuses for improved transfer control protocol (TCP) acknowledgement transmission during operation of a slow-start process in wireless environments. For example, in an aspect, the present disclosure presents a method of wireless communication, which may include receiving, at a radio network controller (RNC), a transmission control protocol (TCP) packet for a user equipment (UE) from a server. Furthermore, example methods may include reforming the TCP packet into a set of radio link control (RLC) packets. Additionally, in some examples, such methods may additionally include transmitting the set of RLC packets to a base station. Moreover, such methods may include sending an accelerated TCP acknowledgement message to the server based on the transmitting of the set of RLC packets to the base station.

  • Publication number: 20090215477
    Abstract: Systems and methodologies are described that facilitate communication between a plurality of devices identified by mobile infospheres. The devices can be associated with a mobile infosphere based on ownership, for example, where the mobile infospheres are identified by a mobile phone number. A registry server can store information regarding devices in each mobile infosphere, and communication between the devices within a mobile infosphere or devices in other mobile infospheres can be facilitated by providing stored access parameters. In addition, data transferred among the devices can be transcoded to meet capabilities of disparate devices with respect to memory, bandwidth, available codes, etc. Moreover, a file system can aggregate shared files and folders from a plurality of mobile infosphere devices to provide seamless access to available accessible content.

  • Patent number: 6725060
    Abstract: A system and method for reducing power consumed by an integrated electronic device. The device includes a personal data assistant (PDA) unit and a wireless telephone integrated in a common housing. A common display on the housing is used for displaying messages from both the PDA and the wireless telephone to a user. A controller, coupled to the wireless telephone, places the wireless telephone in a power-off state after expiration of a predetermined period of time following cessation of voice traffic activity on the wireless telephone. The controller switches the wireless telephone from the power-off state to a power-on state if, during operation in the power-off state, a user begins an attempt to place an outgoing call with the wireless telephone. The wireless telephone is unable to receive an incoming call when the wireless telephone is in the power-off state.
