Abstract

In order for efficiently managing communications between a UE (10) and multiple SCSs (20_1-20_n), the UE (10) includes, in one message, multiple pieces of data to be transmitted to the SCSs (20_1-20_n), and sends the message to an MTC-IWF (30). The MTC-IWF (30) receives the message from the UE (10), and distributes the date to the SCSs (20_1-20_n). Each of the SCSs sends (20_1-20_n), to the MTC-IWF (30), data to be transmitted to the UE (10) and an indicator that indicates for the SCSs (20_1-20_n) the time tolerance until the data is transmitted to the UE (10). The MTC-IWF (30) receives the data and the indicators from the SCSs (20_1-20_n), and determines when to forward the data to the UE (10) based on the indicators.

Claims

1. A system for a mobile communication, comprising:

a UE (User Equipment);

an MME (Mobility Management Entity) or an SGSN (Serving GPRS Support Node);

multiple SCS (Service Capability server); and

a node that connects to the multiple SCSs;

wherein each of the multiple SCSs sends a message including UE ID, data and a tolerance time to the node,

the node waits to deliver the data to the UE based on the tolerance time, and

the node delivers the data to the UE via the MME or the SGSN.

2. A method of a mobile communication system, comprising:

sending, by each of multiple SCS (Service Capability server)), a message including UE ID, data and a tolerance time to a node;

waiting, by the node, to deliver the data to the UE based on the tolerance time; and

delivering, by the node, the data to the UE via an MME (Mobility Management Entity) or an SGSN (Serving GPRS Support Node).

3. The method of claim 2, wherein the data is confidentiality and/or integrity protected.

4. The method of claim 2, wherein the UE and the multiple SCSs protect the data by using a shared key.

5. A node in a mobile communication system, comprising:

a receiver configured to receive a message including UE (User Equipment) ID, data and a tolerance time from each of multiple SCS (Service Capability server);

a sender configured to deliver the data to the UE via an MME (Mobility Management Entity) or an SGSN (Serving GPRS Support Node); and

a controller configured to wait to deliver the data based on the tolerance time.

6. A method of a node in a mobile communication system, comprising:

receiving a message including UE (User Equipment) ID, data and a tolerance time from each of multiple SCS (Service Capability server);

delivering the data to the UE via an MME (Mobility Management Entity) or an SGSN (Serving GPRS Support Node); and

waiting to deliver the data based on the tolerance time.

7. The method of claim 6, wherein the data is confidentiality and/or integrity protected.

8. The method of claim 6, wherein the UE and the multiple SCSs protect the data by using a shared key.
