A method for wireless communications testing using downlink (DL) signal transmissions from an access point to a mobile terminal and uplink (UL) signal transmissions from said mobile terminal to said access point. Accurate block error rate (BLER) testing of LTE mobile devices in a wireless signal environment is enabled by preventing repeated transmissions of the same downlink (DL) data block that would normally follow reception of uplink (UL) transmissions of negative UL acknowledgments (NACKs) caused by failures to decode prior DL data transmissions, thereby producing cumulative NACK counts accurately reflecting data reception errors.

Method for wireless communications testing using downlink and uplink transmissions between an access point and mobile terminals

Method for testing one or more of a group of radio frequency (RF) data packet signal transceiver devices under test (DUTs) with reduced signal interference from the remaining DUTs. A tester broadcasts a signal containing power control instructions about uplink signal power characteristics for communication with the tester. For example, for the LTE 3GPP standards, such characteristics could include power ramping step size, preamble initial received target power or maximum number of preamble transmissions for uplink signals transmitted from the DUTs. Following initiation of communication between the tester and one or more DUTs, the tester broadcasts a signal containing power control instructions to instruct the remaining DUTs to transmit any future signals with different uplink signal power characteristics. For the LTE 3GPP standards, such different characteristics could include reduced power ramping step size, reduced preamble initial received target power or reduced maximum number of preamble transmissions for uplink signals.

A method and apparatus controls diversity reception in a wireless communication device. By determining a value based on a number of active set pilot signals received from a set of base stations, the wireless communication device dynamically enables or disables diversity reception. Diversity reception can be controlled by adjusting a diversity threshold based on the determined value. A channel quality indicator of a channel is measured and compared against the adjusted diversity threshold. The diversity reception mode is then enabled or disabled based on the comparison. For example, if the number of active pilot signals is above a predetermined value, indicating 'good' coverage, the diversity threshold is decreased. The measured channel quality indicator is compared against the adjusted threshold, and diversity reception is enabled when the channel quality indicator is less than the decreased diversity threshold.

Diversity control in a wireless communications device

A system () includes a mobile station () to initiate an outgoing communication anywhere in a coverage area (). A base station () and a radio access network () provide wireless service to the mobile station (). The mobile station is paged in the sectors overlapping with only the clean zone. The mobile station () is paged in the sectors overlapping with the hot zone if the mobile station has predetermined trusted characteristics, or the mobile station is located within a clean zone of sectors overlapping with the hot zone, and an incoming communication for the mobile station originates from a predetermined trusted source. Existing calls to the mobile station are terminated in response to the existing call exceeding a predetermined threshold time limit, or a detected amount of voice activity in the existing call being below a predetermined threshold level.

Method and apparatus for selectively modifying a portion of a radio access network via a homeland security alert system

An embodiment generally relates to a method of maximizing network efficiency. The method includes determining a state of a connect attempt from a network and re-transmitting a connect attempt response message to the network in response to the network's connect attempt being in a pending state after an attempt to setup a connection to the network fails.
