Abstract
Abstract A method and a multi-mode mobile communication device operating said method are provided. The method comprises a multi-mode mobile communication device selecting a first data connection carried over a first radio access technology (RAT) based on a first requested QoS, and the multi-mode mobile communication device selecting a second data connection over a second RAT based on a second requested QoS. The multi-mode communication device comprises a first transceiver adapted to be connected to a server using the first RAT, a second transceiver adapted to be connected to the server using the second RAT, and a processor for carrying out the method.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
153 words
A method, in a mobile communications device capable of operating using a first radio access technology (RAT) and a second RAT, the method comprising: operating the device in idle mode; prioritizing the first RAT over the second RAT based on a first optimization criteria; establishing, over a first network using the first RAT, a first connection to a network node; in response to an indication, on the first RAT, of a pending data session: considering a second optimization criteria; establishing, over a second network using the second RAT, a second connection to the network node in response to the considering of the second optimization criteria; prioritizing the second data connection based on the second optimization criteria; initiating the pending data session, with the network node, over the second data connection; and upon completion of the data session, returning to idle mode and prioritizing the first data connection based on the first optimization criteria.
Claim 2
Independent Claim
153 words
A method, in a mobile communications device capable of operating using a first radio access technology (RAT) and a second RAT, the method comprising: operating the device in idle mode; prioritizing the first RAT over the second RAT based on a first optimization criteria; establishing, over a first network using the first RAT, a first connection to a network node; in response to an indication, on the first RAT, of a pending data session: considering a second optimization criteria; establishing, over a second network using the second RAT, a second connection to the network node in response to the considering of the second optimization criteria; prioritizing the second data connection based on the second optimization criteria; initiating the pending data session, with the network node, over the second data connection; and upon completion of the data session, returning to idle mode and prioritizing the first data connection based on the first optimization criteria.
Claim 3
Dependent Claim
15 words
The method of claim 1 , wherein the pending data is mobile-originating on an uplink.
Claim 4
Dependent Claim
15 words
The method of claim 1 , wherein the pending data is mobile-terminating on a downlink.
Claim 5
Dependent Claim
34 words
The method of claim 3 , further comprising initiating the data session on the first connection prior to establishing the second connection to the network node over the second network using the second RAT.
Claim 6
Dependent Claim
20 words
The method of claim 3 , further comprising monitoring the downlink for the arrival of data, on the first RAT.
Claim 7
Dependent Claim
16 words
The method of claim 1 , wherein the first optimization criteria is a power saving criteria.
Claim 8
Dependent Claim
16 words
The method of claim 1 , wherein the second optimization criteria is a high throughput criteria.
Claim 9
Dependent Claim
28 words
The method of claim 1 , wherein, in idle mode, the wake-up frequency of the first RAT is lower than a corresponding wake-up frequency of the second RAT.
Claim 10
Dependent Claim
26 words
The method of claim 1 , wherein, in active mode, the throughput of the second RAT is higher than a corresponding throughput of the first RAT.
Claim 11
Dependent Claim
19 words
The method of claim 1 , wherein the second criteria is considered when the first data connection is active.
