1. A method, comprising:
- determining an interference between radio parameters of an existing radio connection and radio parameters of a new radio connection created,wherein the radio parameters comprise at least one of frequency, time, and space domain parameters, andwherein the existing radio connection utilizes a radio access technology different from a radio access technology of the new radio connection;
adjusting at least one of frequency and space domain radio parameters of the existing radio connection so as to reduce interference between the at least one existing radio connection and the new radio connection; and
initiating establishment of the new radio connection after the adjustment.

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.

11. A method, comprising:
-
detecting interference between two simultaneous operating radio connections in a communication device; comparing transmission timings of one other radio connection to determine whether a poor performance in at least one of the two radio connections is due to simultaneous transmission; and adjusting at least one parameter of at least one radio connection of the two radio connections so that interference between the at least two radio connections is reduced when interference is determined due to the simultaneous transmission. - View Dependent Claims (12, 13, 14, 15, 16)

17. An apparatus, comprising:
-
a processor; and a memory including computer program code, the memory and the computer program code configured to, with the processor, cause the apparatus at least to create at least one radio connection as an existing radio connection, process a request to create a new radio connection, determine whether or not the existing radio connection utilizing a first radio access technology and the 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, adjust at least one of frequency domain and space domain radio parameters of the existing radio connection so as to reduce interference between the 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 establish the new radio connection after the adjustment of the at least one radio parameter of the existing radio connection. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
