Currently, network utilization and performance are diminished due to capacity issues, which may be resolved by adding hardware / software to spread traffic uniformly according to network element usage information. Disclosed is a method of and corresponding apparatus for resolving network element capacity issues in a wireless network by inspecting data traffic content for information about wireless network elements and data traffic content, collecting said information, and managing (e.g., shaping and steering) the incoming traffic based on the information. Examples of said information include radio bearer resource information for network elements and traffic associated with a wireless access portion of the wireless network and radio access bearer information for network elements and traffic associated with a backhaul portion of the wireless network. By employing embodiments of the invention, network utilization and performance may be increased using existing wireless network elements in a manner overlaid on existing network optimization techniques (e.g., load balancing).

An improved connectivity to radio access point is enabled by a server that includes a database storing data about various radio access points, and an evaluation module evaluating the quality of connection to each of the access points. Clients receive updates about relevant access points from the server and use the information to connect to the preferred access point. The clients also check connectivity to other access points in the vicinity, and report the findings to the server. The server uses the reports to update its database, and send corresponding updates to the clients. The database can include information about the location of the access points. The information about the location of the access points can be manually input or determined using GPS information. The location of an access points can be determined as a function of available information about other access points detected at the same location. An access point can be presumed to be located in approximately the same location as another access point detected in the same location by the same user terminal. Where more than one access point having a known location is detected in the same location as an unmapped access point (having an unknown location), the location of the unmapped access point can be determined as function of a weighted average of the known locations of the other access points and signal strength of the signal received from each access point.

An ad-hoc, peer-to-peer radio access system for cellular communications systems using time division duplex as a way of maximizing the bits / hz / km2 for cellular systems. The network architecture of the ad-hoc system allows the radio access to be integrated with the fixed components of a conventional cellular system, PSTN or ISP. The objective is to make the system of the invention transparent to the features and services provided by the external network. The advantages of such a system to a cellular operator are that significantly less infrastructure is required, and that the RF spectrum is more efficiently utilized resulting in much lower building and operating costs. The system architecture is comprised of remote terminals, routers, gateways, and at least one gateway controller that interfaces the ad-hoc system to a cellular network system. The ad-hoc system of the invention allows for both voice and data transmissions and receptions.

The present invention provides a method for implementation in mobile unit that is configured to communicate with a wireless communication system that includes macrocells and femtocells. The macrocells and the femtocells use different generation radio access technologies. The method includes determining a distance between the mobile unit and the femtocell(s) and transmitting a first measurement report when the distance between the mobile unit and the femtocell(s) is less than a threshold distance. The method also includes performing an inter-radio access technology handoff from the base transceiver station to the femtocell when the distance is less than a threshold distance.

Communication systems and methods are provided allowing a single mode mobile terminal to support mobile assisted signal strength measurement operations in both a fixed frequency reuse based communication network and an adaptive channel allocation based communication network. Candidate base station signal strength measurements are requested by a fixed frequency reuse type network, measured by the mobile terminal and provided to the fixed frequency reuse type network which is seeking to identify a strongest signal for mobile assisted handover operations. In addition, interference signal strength measurements are requested by an adaptive channel allocation type network, measured by the mobile terminal and provided to the adaptive channel allocation type network by the mobile terminal. No redundant circuitry is required in the mobile terminal. Instead, the mobile terminal executes the same operations using the same hardware regardless of whether the requested measurement is of a candidate signal strength or an interference signal.
