Abstract

According to a first aspect of the present invention there is provided an apparatus configured to operate as a subscriber server (2). The apparatus comprises a memory (11) for storing the subscription information of one or more Machine Type Communications, MTC, subscribers, the subscription information of a MTC subscriber including one or more MTC Features and information regarding the MTC subscriber'"'"'s subscribed services, a processor (10) for assessing which of the one or more subscribed MTC Features are supported, assessing any interaction that may occur between each of the supported subscribed MTC Features and between each of the supported subscribed MTC Features and the subscribed services, and determining the subscription information that should be sent to a serving node (1) based on the outcome of the assessments, and a transmitter (13) for sending the determined subscription information to the serving node (1).

Claims

1. An apparatus configured to operate as a subscriber server, the apparatus comprising:

a memory configured to store subscription information of one or more Machine Type Communications (MTC) subscribers in a subscription information database, the subscription information of a MTC subscriber including one or more MTC Features and information regarding the MTC subscriber'"'"'s subscribed services, and store executable instructions for a processor to implement a determination unit and a message generation unit;

a processor configured to execute the instructions of the determination unit in order to assess which of the one or more subscribed MTC Features are supported, assess if interactions occur among the supported subscribed MTC Features, assess interactions that may occur between each of the supported subscribed MTC Features and the subscribed services, and determine based on the outcome of the assessments the subscription information to be sent in a message to a serving node, the processor being configured to execute the instructions of the message generation unit in order to generate the message with the determined subscription information; and

a transmitter configured to send the message with the determined subscription information to the serving node.

2. The apparatus as claimed in claim 1, wherein, when assessing which of the one or more subscribed MTC Features are supported, the processor is further configured to determine if any of the subscribed MTC Features are not supported by the MTC Device and/or by a network in which the serving node is provided.

3. The apparatus as claimed in claim 2, wherein the processor is configured such that, if any of the subscribed MTC Features are not supported by the MTC Device and/or by a network in which the serving node is provided, then the subscribed MTC Features that are not supported are excluded from the subscription information that is to be sent to the serving node.

4. The apparatus as claimed in claim 2, wherein, when determining if any of the subscribed MTC Features are not supported by the MTC Device or by a network, the processor is further configured to perform one or more of:

determining if an indication that one or more MTC Features are not supported by the MTC Device and/or by the network has been received from the serving node; and

for any MTC Features that require an explicit indication that they are supported by the MTC Device and/or by the network, determining if an indication that one or more MTC Features that are supported by the MTC Device and/or by the network has been received from the serving node.

5. The apparatus as claimed in claim 1, wherein, when assessing if interactions occur among the supported subscribed MTC Features, the processor is further configured to:

determine if any of the supported subscribed MTC Features interacts or conflict with any other supported subscribed MTC Feature.

6. The apparatus as claimed in claim 5, wherein the processor is configured such that, if any of the supported subscribed MTC Features interacts or conflicts with any other supported subscribed MTC Feature, then an indication of a relative importance associated with each of these MTC Features is included in the subscription information that is to be sent to the serving node.

7. The apparatus as claimed in claim 1, wherein, when assessing if interactions occur between each of the supported subscribed MTC Features and the subscribed services, the processor is further configured to:

determine if any of the supported subscribed MTC Features imply restrictions on the subscribed services.

8. The apparatus as claimed in claim 7, wherein the processor is configured such that, if any of the supported subscribed MTC Features imply restrictions on the subscribed services, then the subscribed services that are not allowed by the restrictions of the supported subscribed MTC Features are excluded from the subscription information that is to be sent to the serving node.

9. The apparatus as claimed in claim 1, wherein the processor is further configured to determine if any of the supported subscribed MTC Features should only be enabled upon an explicit instruction received from the MTC Device.

10. The apparatus as claimed in claim 9, wherein the processor is configured such that, if any of the supported subscribed MTC Features should only be enabled upon an explicit instruction received from the MTC Device, then an indication is included in the subscription information to be sent to the serving node, wherein this indication indicates that these supported subscribed MTC Features should only be enabled upon an explicit instruction received from the MTC Device.

11. The apparatus in claim 1, wherein the MTC Features include multiple ones of the following:

Low Mobility, Time Controlled, Time Tolerant, Packet Switched (PS) Only, Small Data Transmissions, Mobile Originated Only, Infrequent Mobile Terminated, MTC Monitoring, Priority Alarm Messages, Secure Connection, Location Specific Trigger, Network Provided Destination for Uplink Data, Infrequent Transmission, and Group Based MTC Features.
