A method for aiding emergency responders in retrieving a path, including receiving motion data from a first motion sensor registering motion of a first emergency responder of at least one emergency responder exploring an emergency scene; compiling track data based on the motion data of the first motion sensor, wherein the track data represents a first track of the first emergency responder through the emergency scene; calculating path data based on the track data, wherein the path data represents a path coinciding with at least a part of the track; and providing the path data to an actuator arranged for guiding an emergency responder of the at least one emergency responder along the path.

A load condition of a cell is determined without having to measure one or more radio parameters pertaining to the cell load, e.g., interference level. Based upon that determined load condition, a traffic condition of the cell may then be regulated, e.g., admission and/or congestion control, transmit power control, etc. The load condition is determined simply and accurately by observing the value (absolute or weighted) of transmit power control commands issued in the cell over a particular time period. To identify potential 'false alarms' of increased cell loads, a radio parameter associated with another frequency band in another cellular system that impacts the load condition of the cell in the current cellular system is measured. A traffic condition in that cell is regulated based upon the determined load condition in the cell taking into account the measured radio parameter.

A load condition of a cell is determined without having to measure one or more radio parameters pertaining to the cell load, e.g., interference level. Based upon that determined load condition, a traffic condition of the cell may then be regulated, e.g., admission and/or congestion control, transmit power control, etc. The load condition is determined simply and accurately by observing the value (absolute or weighted) of transmit power control commands issued in the cell over a particular time period. In one example implementation, the number of increase transmit power commands issued in a cell over a particular time period is determined relative to a total number of transmit power commands, (i.e., both increase and decrease), issued in the cell for that same time period. If the number of increase transmit power commands relative to the total number of transmit power commands exceeds a threshold, an overload condition may be indicated. When an overload is indicated, an action may be taken that reduces the number of increase transmit power commands issued in the cell. Alternatively, a difference between the number of increase and decrease transmit power commands may be used.

A telecommunications system ( ) has a capacity management system ( ) which provides a user equipment unit agent ( ) for each wireless user equipment unit ( ) with which a connection is to be established. The user equipment agent negotiates resources for the prospective connection to be established with its corresponding user equipment unit. In the negotiation, the user equipment agent determines a number of purchase units expendable by the user equipment unit for the negotiation, and issues a resource request to begin the negotiation. Each resource has a resource unit price at which a unit of the resource is sold. In response to the resource request issued by the user equipment agent, connection resources are allocated to the user equipment unit in accordance with what the number of purchase units expendable by the user equipment unit can afford. The resource unit price for the resources is dynamically adjusted, e.g., in accordance with load on the telecommunication system. The resources can include such capabilities as transmission power, spreading code, bit rate, and a number of handover legs (for diversity purposes).
