摘要:
The present invention is related to a method and apparatus for facilitating lossless handover in a wireless communication system comprising at least one wireless transmit/receive unit (WTRU), a source evolved Node B (eNB), a target eNB, and a mobility management entity/user plane entity (MME/UPE) where the WTRU is in wireless communication with the source eNB. The source eNB determines to handover the WTRU to the target eNB, requests status reports from the WTRU, and requests handover to the target eNB. The handover request includes context information relating to the WTRU which is sent to the target eNB. The target eNB configures resources for the WTRU and transmits a handover response signal to the source eNB. The source eNB commands the WTRU to perform a handover to the target eNB and forwards data to the target eNB. The WTRU performs the handover to the target eNB.

The invention performs long term evolution (LTE) tracking area updates (TAUs), and tracking area code (TAC) and public land mobile network identification (PLMN-ID) assisted optimized wireless transmit/receive unit (WTRU) cell reselection. An evolved Node-B broadcasts system information including at least one system information block (SIB) based at least in part on an enhanced universal terrestrial radio access network (E-UTRAN) parameter response message sent by an evolved packet core (EPC) network. A WTRU generates a new TAC, which represents a tracking area identification (TA-ID) of a new cell, based on the system information, and compares the new TAC to an existing TAC, which represents a TA-ID of a previous cell. The WTRU transmits to the EPC network a TAU request message including the TA-ID of the new cell. The EPC network sends either a TAU accept message or a TAU reject message to the WTRU.

A method for configuring an enhanced Node B (eNB) in a long term evolution (LTE) wireless communication network includes providing information to the eNB, wherein the eNB can perform a self-configuration process based on the provided information. An eNB for use in an LTE wireless communication network includes a universal integrated circuit card and a service control module. The universal integrated circuit card includes information that the eNB can use to perform a self-configuration process. The service control module is configured to receive the circuit card and read the information on the circuit card.

A method for performing rate control for VoIP services using messages to enable the RRC to be aware of activity in the SIP/ARM level and to recommend an AMR rate change according to conditions in a wireless communication network. The messages allow VoIP services to dynamically adjust both rate and voice quality based on network conditions. A method for triggering RRC codec rate control using RRM conditions in the network. A method for coordinating AMR autonomous rate control and RRC commanded rate control using a guard mechanism between messages.

Embodiments of the invention provide a hydraulic isolator to split a volute of a pump into two compartments. The hydraulic isolator is positioned within the volute and includes an inlet positioned around a volute inlet channel of the pump, and an outlet positioned adjacent to an outlet channel of the pump. The hydraulic isolator also includes a toroidal portion to at least partially surround an impeller of the pump.

A method of splicing a power cable used to supply electricity to down hole submersible pumps uses a pair of annular armored seal members that are slid over the ends of an insulated electrical conductor being spliced together. Each armored seal member has a plurality of O-ring seals on one end thereof and a plurality of openings in the side thereof and are used to cover and protect a crimped conductor being spliced together. The method and apparatus allow a pair of spliced electrical cables to be used in an adverse environment.

A method provides an interconnect structure having enhanced structural support when underlying functional metal layers are insulated with a low modulus dielectric. A first metal layer having a plurality of openings overlies the substrate. A first electrically insulating layer overlies the first metal layer. A second metal layer overlies the first electrically insulating layer, the second metal layer having a plurality of openings. An interconnect pad that defines an interconnect pad area overlies the second metal layer. At least a certain amount of the openings in the two metal layers are aligned to improve structural strength of the interconnect structure. The amount of alignment may differ depending upon the application and materials used. A bond wire connection or conductive bump may be used with the interconnect structure.
