Abstract
Some embodiments of the invention concern a method of communication in a cellular network between a base station and a user equipment, comprising a step (S2) of providing, from base station to user equipment, a new allowed maximum transmitting power lower than former allowed maximum transmitting power because of traffic load increase within base station cell, wherein, if user equipment sends later on a message, to base station, with a transmitting power exceeding said new maximum, base station may decide not to reject (S10, S15) user equipment message depending on at least one condition.

Method of communication in a cellular network between a base station and a user equipment, comprising:
- providing, from the base station to the user equipment, a new allowed maximum transmitting power, wherein the new allowed maximum transmitting power is lower than a former allowed maximum transmitting power if a specific traffic load increase has occurred within the base station cell;
- and
- wherein the method also comprises, if the user equipment sends a message to the base station with a transmitting power exceeding said new allowed maximum transmitting power, deciding, by the base station, depending on at least one condition whether or not to reject the user equipment message.
Base station of cellular network comprising:
- a transmitter adapted to provide a user equipment with a new allowed maximum transmitting power lower than former allowed maximum transmitting power if a specific traffic load increase has occurred within the base station cell,
- a receiver adapted to receive a message from said user equipment,
- wherein the base station also comprises a controller adapted, if the transmitting power of said received message exceeds said new maximum, to decide, depending on at least one condition, whether or not to reject said received message.
User equipment of cellular network comprising:
- a receiver adapted to receive from a base station a new allowed maximum transmitting power lower than a former allowed maximum transmitting power if a specific traffic load increase has occurred within the base station cell,
- a comparator adapted to compare said new maximum with its own needed transmitting power minimum to send a message to base station,
- wherein the user equipment also comprises:
- a transmitter adapted, if said own minimum exceeds said new maximum, to still send, to said base station, a message with said own minimum needed transmitting power,
- a processor adapted to signal an indication of an excess power of said sent message with specific information field associated with the sent message.
