Abstract
A method for controlling a number of simultaneous radio connections in a communication device is presented. The control of a number of simultaneous radio connections is carried out in the communication device. Parameters of the radio connections are controlled such that interference between the radio connections is minimized.
Claims40
A method, comprising:
- determining whether or not at least one existing radio connection utilizing a first radio access technology and a new radio connection being created and utilizing a second radio access technology interfere with one another on the basis of comparison of radio parameters of the existing radio connection and the new radio connection, wherein the radio parameters relate to at least one of frequency, time, and space domain parameters;
- and
- adjusting at least one of frequency and space domain radio parameters of the at least one existing radio connection so as to reduce interference between the at least one existing radio connection and the new radio connection. when it has been determined that the creation of the new radio connection will cause too high interference between the radio connections;
- and
- initiating establishment of the new radio connection after the adjustment of the at least on radio parameter of the at least one existing radio connection.

A method, comprising:
- monitoring properties of at least two simultaneously operating radio connections in a communication device in order to detect interference between at least two radio connections;
- comparing, upon detection of poor performance in at least one of the at least two radio connections, transmission timings of at least one other radio connection in order to determine whether or not the poor performance in the at least one of the at least two radio connections is linked to simultaneous transmission;
- and
- adjusting parameters of at least one radio connection of the at least two radio connections so that interference between the at least two radio connections is reduced when interference linked to the simultaneous transmission between the at least two radio connections is determined to exist.
