Patent ID: 8385242

Claim:
A method for reducing current consumption in a communication terminal, wherein the communication terminal comprises one or more always-on applications arranged to send and receive messages relating to said one or more always-on applications to and from one or more always-on application servers connected to a communication network, the sending and receiving being carried out according to a messaging pattern specific to each always-on application; the method comprising: gathering, by said communication terminal, information on the messaging pattern of at least one always-on application within said communication terminal; gathering information on parameters of communication channels allocated for said sending and receiving of said messages; determining an allowable transmission delay for said messages; combining, in said communication terminal, messages from said one or more always-on applications during said allowable transmission delay into a group of messages; determining a uniform messaging pattern for said messages of said one or more always-on applications separately for an uplink direction and a downlink direction according to the following rule: i) determining, from said group of messages, a message package including the number of messages transmittable within the transmission capacity of the most energy efficient communication channel, and ii) determining a transmission interval for the message packages; transmitting, by said communication terminal, the messages within said group of messages on the most energy efficient communication channel during said allowable transmission delay; or if the size of a smallest possible message package exceeds the transmission capacity of the most energy efficient communication channel, arranging, by said communication terminal, said message package to be transmitted on a next most energy efficient communication channel having a transmission capacity for transmitting said message package; transmitting said uniform messaging pattern for the downlink direction to said one or more always-on application servers; and arranging the downlink messaging by means of said one or more always-on application servers and a channel resource function of the communication network.
