摘要： A method of connection setup in mobile wireless data communications systems is disclosed where the connection setup time is decreased for delay-sensitive communications sessions relative to the normal connection setup time for confidence-dependent communications sessions. This is achieved by performing some of the connection set-up steps for delay-sensitive communications sessions after successfully demodulating a smaller number of indications identifying an access terminal's desired serving resource than would be demodulated in the case of a confidence-dependent communication session prior to performing the same connection set-up steps.

摘要： A method and system for connection management in a wireless data network, such as a 1×EV-DO network adds connections to new network sectors upon receipt of a connection request from an active terminal, but removes data connections that the active terminal requests to be dropped only after confirmation from the active terminal that a channel allocation message has been received and applied. The active network maintains an active set of connections that is at least as large as the active set maintained by the active terminal and does not initiate a connection termination if no confirmation of the channel allocation message is received. This allows for a reduction in the number of dropped connections.

摘要： A cellular wireless communication system includes base transceiver stations and mobile stations that operate with a closed loop power control. The mobile tracking is performed based on the lock in and lock out thresholds by the base transceiver stations. A forward link power control bit is decoded from the reverse channel. An additional threshold is introduced for determining at the base transceiver station whether the decoded forward link power control bit is valid or invalid. The finger energies obtained from a finger processor formed by a RAKE receiver of the base transceiver station are compared to the additional validation threshold. The additional validation threshold is independent of the tracking thresholds and usually greater than them. The validation performance may not be affected by low signal/noise. The forward link traffic channel gain of the base transceiver station is controlled in response to the invalidity of the decoded forward power control bit. The decoding of the reverse link power control bit and the validity determination of the decoded reverse link power control bit are performed by similar methods to those of the forward link power control bit. With improved validation methods, the forward link and reverse link transmission power is more accurately controlled.

摘要： The present solution enables a packet switched connection to be temporarily released at the wireless terminal for supporting voice calls over a Circuit-Switched (CS) Fallback. The packet switched connection of the LTE core network retained for a pre-defined period of time during the CSFB session allowing the user to quickly switch back to the packet switched connection when the CSFB session is shorter than the predefined period or when the voice call CSFB attempt fails. This is accomplished by the introduction of a timed buffer to control the length of time the LTE core network connection and wireless context information will be retained.
摘要翻译：本解决方案使得能够在无线终端处暂时释放分组交换连接，以通过电路交换（CS）回退来支持语音呼叫。在CSFB会话期间，LTE核心网的分组交换连接保持预定的时间段，允许用户在CSFB会话比预定时间段短时或当语音呼叫CSFB时快速切换回分组交换连接尝试失败。这是通过引入定时缓冲器来实现的，以控制LTE核心网络连接和无线上下文信息将被保留的时间长度。

摘要： Initiation of a hard handoff at a mobile station from an overlay carrier to an underlying carrier in a wireless telecommunications system may be considered based on a first condition being satisfied. Once the first condition is satisfied, hard handoff may be initiated based on at least one of a plurality of further conditions being satisfied. Advantageously, the plurality of further conditions may be arranged to be independent of the total power received at the mobile station and, therefore, independent of loading.
摘要翻译：可以基于满足第一条件来考虑在移动台从重叠载波到无线电信系统中的底层载波的硬切换。一旦满足第一条件，就可以基于满足多个其他条件中的至少一个来启动硬切换。有利地，多个其他条件可以被布置为独立于在移动站处接收的总功率，并且因此独立于负载。
