Automatic device capabilities change notification

摘要

An improved approach to mobile device capability management is described herein where a capability management device is provided at a mobile communication network. Upon change of a mobile device capability, a related notification is sent to the capability management device which applies a policy decision whether to track the capability change at the network side or not. Should the decision be ‘yes’, the capability management device starts a device management session to collect further information on a mobile device capability change beyond the information made available with the mobile device capability change notification. After retrieval of the mobile device capability change information, the capability management device will update its mobile device capability state accordingly.

1. Method of operating a mobile device capability management device in a mobile communication network with respect to at least one mobile device served by the mobile communication network, wherein a mobile device capability is represented as a first mobile device profile in the mobile device capability management device and as a second mobile device profile in the mobile device, the method implemented by the mobile device capability management device comprising the steps:
receiving, at the mobile device capability management device, a mobile device capability change information (CHAN) with respect to a capability change of the mobile device, wherein the mobile device capability change information (CHAN) contains a qualitative parameter indicating a degree of change to a management tree of the second mobile device profile and a quantitative parameter indicating amount of effective changes to the management tree of the second mobile device profile; and assessing, at the mobile device capability management device, the need to update the first mobile device profile on the basis of a mobile device capability management policy and the received mobile device capability change information.
