In one aspect of the teachings herein, a Services Capability Layer, SCL, within a Machine-to-Machine, M2M, network generates unique identifiers, for use in identifying individual application instances within the M2M domain. According to such operation, an SCL receives or otherwise obtains an application identifier for an application instance registering at the SCL, and generates a globally unique identifier for the application instance using the application identifier or an alias corresponding to it. As an example, the SCL appends to the application identifier or alias its own identifier, which is unique to that SCL, along with a random value. The resultant identifier is guaranteed to be unique for the individual application instance and the SCL uses the resultant identifier for identifying the application instance to other entities within the M2M domain. |
