  • Publication number: 20110268085
    Abstract: Techniques for performing forward handover in a wireless communication system are disclosed. In one aspect, a user equipment (UE) transmits a connection request to a target eNodeB. The connection request may be transmitted when the UE detects a connection failure in a communication with a source eNodeB. The UE receives a connection response from the target eNodeB in response to the target eNodeB requesting handover preparation information from the source eNodeB. In another aspect, a target eNodeB may receive a connection request from a user equipment (UE) and transmit a radio link failure (RLF) recovery request message to a source eNodeB to prompt the source eNodeB to initiate handover of the UE from the source eNodeB.

  • Publication number: 20100158044
    Abstract: Techniques for bundling and ciphering data prior to transmission are described. In an exemplary design, a transmitting entity receives a plurality of service data units (SDUs) from an upper layer, assigns sequential sequence numbers to the SDUs, and bundles the SDUs into a single protocol data unit (PDU). In one design, the transmitting entity generates a single count value based on a sequence number of a designated SDU (e.g., the first SDU) in the PDU and ciphers all SDUs based on the single count value. In another design, the transmitting entity ciphers each segment of at least two SDUs in the PDU based on a count value for that segment. The transmitting entity generates a header with at least one sequence number and possibly length and/or other information for the SDUs. The transmitting entity forms the PDU with the header and the SDUs and passes the PDU to a lower layer.

  • Patent number: 7701896
    Abstract: In accordance with the teachings of the present invention, a method and apparatus is presented for registering a mobile IP node with a home agent. A self-selection method is implemented in a home agent. When a home agent receives a registration request from the mobile node, the self-selection method enables each home agent to independently and randomly generate a value that falls within a range of numbers. Each range of numbers is referred to as a bin. In addition, each home agent is associated with at least one of bin. If the value falls within the bin, the home agent associated with the bin responds to the registration request. In addition, home agents are uniformly selected relative to other home agent on the network; therefore, implementing the self-selection method performs load balancing in the network.

  • Publication number: 20100034169
    Abstract: Explicit signaling of End of Handover (EoH) advantageously indicates when user equipment (UE) has stopped using Packet Data Convergence Protocol (PDCP) handover mode. Radio Link Control (RLC) Acknowledge Mode (AM) delivers in order ensuring that all reordered packets have been received with no risk of delivering a gap packet when no longer in handover mode that would otherwise cause Hyper Frame Number (HFN) to be out of synchronization. Substantially at a time evolved Base Node (eNB) determines a gap will not be filled, eNB can convey an EoH indication to a served UE and can then deliver the PDCP Service Data Units (SDUs) with gaps to upper layers without delay.

  • Publication number: 20090316652
    Abstract: Systems and methodologies are described that facilitate indicating global cell identifier (GCI) reporting in wireless communication to mitigate confusion caused by physical cell identifier (PCI) reporting in heterogeneous deployments. In particular, mobile devices can report GCI of access points to disparate access points to facilitate communication therebetween, such as during handover. Mobile devices can indicate GCI reporting during a system access request by selecting an access sequence corresponding to subsequent GCI reporting. Based on the access sequence, an access point can grant additional resources to receive the GCI, and the mobile device can communicate GCI over the resources. Using the GCI, the access point can communicate with a disparate access point related to the GCI.

  • Publication number: 20090310540
    Abstract: A mobile communications system includes a radio access network, such as an Enhanced General Packet Radio Service (EGPRS) network, in which mobile stations are able to enter into a discontinuous transmission (DTX) mode. During DTX mode of a first mobile station that is allocated a channel portion (e.g., a time slot of a frame), the radio access network is able to multiplex traffic from another mobile station onto the same channel portion. A mechanism is provided to enable the first mobile station to send a request for re-allocation of the channel portion. The request includes a real-time fast access associated control channel (RTFACCH) resource request message (RTRRM). In response to the RTRRM, the radio access network sends an RTFACCH resource assignment message (RTUAM).

  • Patent number: 7072336
    Abstract: A communications network includes a data network that is coupled to a wireless access network and other devices. The wireless access network enables access by mobile stations of the data network. Each mobile station, and optionally, one or more of other devices coupled to the data network, contains an adaptive multi-rate codec (coder/decoder) that can be set to operate at a plurality of rates. Based on the selected one of the plurality of rates, the mobile station or other device sets a quality-of-service (QoS) indicator value in a packet carrying data, such as real-time data, over the wireless access network and/or data network. By varying QoS requirements using the QoS indicator value for different codec rates, bandwidth requirements are varied so that more efficient usage of the data network is provided.

  • Patent number: 6839356
    Abstract: A wireless network and serviced mobile station manages VOIP telephony calls by incorporating control information into VOIP datagrams. The control information includes an indication of the data rate of the VOIP payload of the VOIP datagram, the quality of the VOIP payload, requested data rates for subsequent VOIP datagrams, and whether the VOIP payload contains a “silent” VOIP payload. To avoid conflicting with particular datagram requirements, the control information is inserted into the VOIP datagram between the VOIP datagram and the VOIP payload. A base station servicing the wireless link may override the requested data rate and/or the commanded data rate in order to manage its available wireless bandwidth among a plurality of mobile stations. The frame quality indicator may be set by the servicing physical/mac/link layer(s) of the base station or mobile station to indicate that the VOIP payload was not correctly received.
