  • Method for managing CS IRAT handover from 2G/3G network to LTE network
    Patent number: 9232445
    Abstract: The invention relates to a method to manage a CS IRAT (Circuit Switch Inter RAT) handover of a user equipment (UE) from a 2G/3G network to a LTE (Long Term Evolution) network in which: the UE transmits its CS IRAT handover from 2G/3G to LTE capabilities to the BSC/RNC node; the BSC/RNC node selects a routing paths among said different routing paths based on the UE capabilities for CS IRAT handover from 2G/3G to LTE and transmits to a MSC/VLR node (Mobile services Switching Center) of said 2G/3G network a Handover message comprising an information indicative of the selected path corresponding to the selected CS handover technology; and the MSC/VLR node transfers said Handover message to said target eNodeB through a MME (Mobility Management Entity) node or through an IWF node (Interworking Function) depending on the selected CS handover technology.

  • Method for transmitting mini-messages and associated device
    Patent number: 9055355
    Abstract: To reduce the call cost for user messages of a few tens of bytes through a mobile telephone network (3), and to avoid having to set up a call channel as is necessary for transmitting data of several thousands of bytes, spare fields in signaling messages are used to convey the user messages, a call then taking place via signaling messages, and without a dedicated call channel being set up.
