Abstract: Various types of information from a wireless communications network, including E911 location information, Hand Off (HO) information, and Power information, as well as other Measurements and System Parameters, are collected and analyzed by a Data Collection and Filtering system, and the results of this analysis are provided to a Network Control system to dynamically control the operation of the wireless communications network. The various optimizations that can be performed by the Network Control system include: (1) dynamically allocating radio frequency (RF) signal power, (2) setting dynamic dedicated handoff (HO) thresholds for individual mobile transceivers; and (3) intelligently forming or steering radio frequency (RF) signal beams.

This information is analyzed by a Data Collection and Filtering system and the results of this analysis are provided to a Network Control system to dynamically control the operation of the wireless network. The various optimizations that can be achieved include: (1) dynamically allocating radio frequency (RF) signal power in the wireless network, (2) setting dynamic dedicated handoff (HO) thresholds for individual mobile transceivers; and (3) intelligently forming or steering radio frequency (RF) signal beams. Moreover, the collected and analyzed information can be used to identify and resolve problems in the wireless network, especially when the identified problems are correlating with E911 location information.

Abstract: Integration of the cellular network with an IP based network is disclosed. An integrated IP/cellular network can route packetized voice and data together in a more efficient manner. The present invention integrates IP based standards for a cellular IP solution with cellular centric vs. IP message gateway as the demarcation point. However, the present invention also provides support for cellular unique features for better performance. Multiple architectures are proposed to ease migration to a combined network as well as to show the various levels of support provided.

Abstract: Vocoding conversions are reduced by dynamically loading a software-defined vocoder into a handset. The software-defined vocoder may be selected based on the calling party's network type, wherein a notification of network type is transmitted to the called party's network during call setup. The software-defined vocoders may be stored in the network and downloaded into the handset; alternatively, the software-defined vocoders may be stored in the handset. Voice data is tunneled from the calling party's handset and the calling party's network, through any number of different networks, to the called party's network and called party's handset, without any vocoding conversions, except at the handsets.

Abstract: Various techniques ate present for enhancing the quality of service on wireless communications systems. These techniques determine when errors occur in transmitted frames, then apply Bit Error Rate Power Control, Power-Based Re-Transmission, and Sub-Frame Selective Repeat methods to these errors. Consequently, the handling of frame errors consumes fewer resources in the wireless communications systems.

Abstract: Bluetooth networks, also known as wireless local loop, are integrated with cellular networks, so that the two networks can inter-operate with devices enabled for both types of networks.

Abstract: A method for tunneling voice over the Internet Protocol (IP) in a cellular network. A Mobile Identification Number (MIN) of a non-IP-enabled handset is mapped to the IP address of a component of a cellular network in communication with that handset. A sub-index is assigned to the handset by the component, wherein the sub-index acts as an extension to the IP Address of the component, so that a non-IP-enabled handset can be correctly identified within the cellular network.

Abstract: A computer-implemented modeling tool for wireless communications systems predicts signal strength by considering the effects of water on RF signals. The modeling tool creates a model of the RF signals' propagation between a transmitter and a receiver in the wireless communications system. The modeling tool then determines the effect of at least one body of water located between the transmitter and the receiver on the modeled RF signal's propagation. Thereafter, the modeling tool outputs a signal strength value for the modeled RF signal based on the determined effect from the body of water located between the transmitter and receiver.

Abstract: A computer-implemented modeling tool for cellular telephone systems predicts signal strength under real conditions within a building, by considering the effects of inter-building and intra-building structures on transmitted signals. The modeling tool gives more accurate predictions under line of sight conditions, when obstructions occur due to inter-building and intra-building structures.

Abstract: A computer-implemented modeling tool for cellular telephone systems predicts signal strength under real conditions by considering the effects of terrain and man-made structures on transmitted signals. The modeling tool gives more accurate predictions under line of sight conditions, when obstructions occur due to terrain contours, and when mobile or transmitter antennas are blocked by buildings or other structures.
