Abstract: The invention relates to a method for distinguishing between LOCATION REPORT messages to avoid ambiguities. Therefore, a value of an information element of request type is returned by a radio network controller, depending on an intended receiver of the location information. A control node receiving the information element value analyses said value and determines the receiver depending on the result of said analysis.

Abstract: An MTC device activates an MTC service by first performing an MTC device attachment procedure to attach to a mobile communication network. After the MTC device is attached to the mobile communication network, the MTC device activates a packet data protocol context for the MTC device with the mobile communication network. After the packet data protocol context is activated, the MTC device activates an MTC service with an MTC server.

Abstract: In a method and system for transferring a voice call in the packet switched domain to a system supporting both packet switched and circuit switched voice calls, target system, i.e. the system to which an ongoing voice call is transferred is in control of deciding if an ongoing voice call in the originating system should continue in the circuit switched domain or the packet switched domain. In addition the system is enabled to reserve resources in the system to receive the voice call before handing over the voice call.

Abstract: The transmission of a warning message to a mobile terminal in a mobile communication network is triggered by an emergency event. The mobile terminal is first made aware of the need to receive a warning message by reception of an emergency event notification. The warning message is divided into a plurality of message segments. Each segment is transmitted in a separate paging message over a paging channel to mobile terminals in an idle mode. Information is added to each message segment to enable the mobile terminal to discriminate between segments belonging to different warning messages.

Abstract: In densely populated areas a random period of time or an offset is added in order to avoid signaling congestion. Using the described method and system will reduce the signaling peak load on the signaling channels when many subscribers are changing Location Area at the same time. The method and system as described herein are easy to implement and does not require additional hardware resources or configurations on the network side.

Abstract: A method and packet data support node in a radio telecommunications network supporting packet data communication between a packet data network and a mobile terminal in radio communication with a first packet control unit. The packet data support node receives a message from the mobile terminal requesting handover to a second packet control unit. A packet flow context detector in the packet data support node detects the number of packet flow contexts currently active in the first packet control unit for supporting the packet data connection. The detector sends a message during handover to the second packet control unit indicating the number of active packet flow contexts. The message is used for activation of a corresponding number of packet flow contexts in the second packet control unit.

Abstract: Upon receipt of a request message from a core network (CN) relating to a procedure for a radio access bearer, a radio network controller node (26) of a radio access network (RAN) sends to a core network a first message (4-2) which includes, e.g., an Internet Protocol (IP) address of the radio network controller node. Subsequently the radio network controller node sends to the core network a second message (4-4) which indicates an outcome of the procedure. In one example implementation, the procedure for the radio access bearer is one of a RAB establish procedure and a RAB modify procedure. The RAB establish procedure can be initiated by an RAB Assignment Request message and is particularly useful for a RAB Assignment Request message which specifies a support mode. In this example implementation, both the first message and the second message are separate transmissions of a RAB Assignment Response message.
