Abstract

In a mobile telecommunications network including at least a first type of radio access network and a second type of radio access network and a mobile terminal, a method of establishing a voice communication with the mobile terminal including: receiving a voice communication request in relation to the mobile terminal on the second radio access network type; determining a parameter associated with a terminal characteristic; and using the parameter to determine whether to establish the voice communication on the first type of radio access network or maintain the voice communication on the second type of radio access network. Preferably the determined parameter is a parameter relating to a terminal type for the mobile terminal, and is determined from the terminal's IMEI.

Dependent claims

receiving a voice communication request in relation to the mobile terminal on the second radio access network type;
determining a parameter associated with a terminal characteristic;
determining an estimated length of the voice communication with the mobile terminal;
and
using the parameter and a battery level of the mobile terminal to determine whether to establish the voice communication on the first type of radio access network or maintain the voice communication on the second type of radio access network, wherein, in a comparison, the estimated length of the voice communication is compared with the battery level, and wherein the comparison is used in determining whether to establish the voice communication on the first type of radio access network or maintain the voice communication on the second type of radio access network.
