Abstract:
En este documento se describe como proporcionar el análisis automatizado de señal de red inalámbrica mediante dispositivos móviles como función de sus ubicaciones geográficas. A manera de ejemplo, una red inalámbrica puede transmitir un conjunto de datos geográficos que definen una región geográfica para un dispositivo móvil. El dispositivo móvil puede comparar su ubicación actual con la región geográfica, y comenzar la medición de señales de enlace descendente, o registrar tales mediciones cuando éste dentro de la región geográfica, y finalizar el registro cuando el dispositivo móvil abandone la región geográfica. Las mediciones registradas se pueden subir posteriormente a la red inalámbrica para su análisis. En algunos aspectos, el dispositivo móvil puede abstenerse de subir las mediciones hasta estar dentro de una región de reporte definida. Al proporcionar activado el análisis de la red del dispositivo móvil en la ubicación geográfica del dispositivo, se pueden obtener los datos del análisis que están bien adaptados a un área problema en particular, incrementando la calidad de los datos de análisis y reduciendo significativamente el costo de la adquisición de tales datos.
Abstract:
Systems and methodologies are described that facilitate providing physical cell identifier (PCI) assignment. Neighboring access point parameters can be collected and transmitted to a PCI assigning component, which can generate a PCI based on the parameters as well as other local parameters. The neighboring access point parameters can be received by evaluating signals transmitted by the neighboring access points, from a UE communicating with the neighboring access points, over a backhaul link, etc. The parameters can include signal strength, identification, and/or the like. In addition, prioritized lists of PCIs can be provided to an access point, which can utilize the neighborhood parameters to select an optimal PCI from the list.
Abstract:
A method and apparatus for generating performance measurements for a wireless network is provided. The method may comprise: obtaining, at a base station, performance measurements and location data from a mobile device, storing, at the base station and based on the location data, at least a portion of the obtained measurements to at least one virtual geographic bin of a storage array, wherein each virtual geographic bin corresponds to a different geographic area within a cell serviced by the base station, aggregating, at the base station, at least a portion the measurements stored in each virtual geographic bin into one or more location-based performance measurements, and transmitting, from the base station, at least a portion of the location-based performance measurements to a network manager.
Abstract:
An apparatus and method for reducing call setup time of a wireless commun ication device including measuring paging intensity, and adjusting SIB7 or S IB14 repetition period based on the measured paging intensity to reduce call setup time. In one aspect, a paging intensity threshold is determined based on the measured paging intensity, and the paging intensity threshold is use d to adjust the SIB7 or SIB14 repetition period.
Abstract:
Handover parameter settings are automatically adapted in access points in a system to improve handover performance. Reactive detection techniques are employed for identifying different types of handover-related failures and adapting handover parameters based on this detection. Messaging schemes are also employed for providing handover-related information to access points. Proactive detection techniques also may be used for identifying conditions that may lead to handover-related failures and then adapting handover parameters in an attempt to prevent such handover-related failures. Ping-ponging may be mitigated by adapting handover parameters based on analysis of access terminal visited cell history acquired by access points in the system. In addition, configurable parameters (e.g., timer values) may be used to detect handover-related failures.
Abstract:
In a Universal Mobile Telecommunications (UMTS) system, a mobile device reads scheduling information for uplink interference (SIB7) from a Master Information Block, broadcasted on the Broadcast Channel (BCCH). The UE wakes up from the sleep during its periodic paging occasions and reads the paging indicator channel (PICH). If the UE needs to read the PCH, then the UE computes the timing of the next broadcast of SIB7 using the scheduling information broadcast in the MIB on BCCH. Knowing the timing of the next SIB7, the UE can determine if there is an overlap. If overlap is detected, the mobile device demodulates both the paging channel carried by the Secondary Common Control Physical Channel (S-CCPCH) and the broadcast channel carried by the Primary CCPCH, avoiding a mobile-terminated (MT) call setup delay by waiting for the next SIB7 broadcast, which depending upon a SIB7 repetition ranges from 360 msec to 2.56 seconds.
Abstract:
La configuración de los parámetros de traspaso se adapta automáticamente en los puntos de acceso de un sistema para mejorar el rendimiento del traspaso. Las técnicas de detección reactiva se emplean para identificar diferentes tipos de fallas relacionadas con el traspaso y adaptar los parámetros del traspaso en función de esta detección. Los esquemas de mensajería también se emplean para proporcionar información relacionada con el traspaso a los puntos de acceso. Las técnicas de detección proactiva también se pueden usar para identificar condiciones que pueden conducir a fallas relacionadas con el traspaso y luego adaptar los parámetros del traspaso en un intento de prevenir tales fallas relacionadas con el traspaso. El ping-pong puede mitigarse adaptando los parámetros de traspaso basados en el análisis del historial de celdas visitadas del terminal de acceso adquirido por los puntos de acceso en el sistema. Además, pueden usarse parámetros configurables (por ejemplo, valores de temporizador) para detectar fallas relacionadas con el traspaso. (Traducción automática con Google Translate, sin valor legal)
Abstract:
sistemas, métodos e aparelhos para controle de potência de rádio de enlace ascendente. em algumas implementações da presente invenção, a melhoria da qualidade de conexão e redução da taxa de ligação interrompida são alcançadas através da suspensão da transmissão de canal de controle físico dedicado de alta velocidade (hs-dpcch), quando um terminal sem fio detecta um modo de potência limitante durante conexões de portador de acesso multirrádio (mrab) e rab de voz está presente, e correspondentemente, aumentando a potência de transmissão de enlace ascendente para canais de voz e dados de sinalização. em algumas implementações, a suspensão de dados hs-dpcch pode ser completa ou parcial. quando estiver totalmente suspensa, nenhum dado é enviado no hs-dpcch. quando parcialmente suspensa, nenhum indicador de qualidade de canal (cqi) é transmitido. em ambos os esquemas de suspensão parcial e total, a transmissão de cqi é suspensa até que o terminal detecte que as condições de entrada para este estado foram encerradas.
