The present invention provides a method and apparatus for network access for consumers in both wired and wireless environments. Multiple-interface/multiple-connections are used to support high-speed handoff and seamless roaming between different networks (wired and wireless). The present invention is implemented by using multiple interfaces and connections to interface a mobile PC unit, providing additional functions, and enhancing current PC device drivers and software.

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.

Network engineering in a wireless network

A and collects provides various types of information therefrom, including E911 location information, Hand Off (HO) information, and Power information, as well as other Measurements and System Parameters. 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.

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.

Tunnelling wireless voice with software-defined vocoders

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.

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.

Integrating wireless local loop networks with cellular networks

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.

Tunnelling voice over the internet protocol in a cellular network

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.
