摘要:
A device and method is provided of administrating an application within a bearer of a mobile communication network. An example method comprises activating by means of a mobile device an application requiring access to the mobile communication network, identifying the application by means of an application identification unit, allocating an application index to the application by means of the application identification unit based on the identification of the application, and coupling the application index to an access request related to the application by means of the application identification unit, such that managing network resources based on the coupled application index is enabled. Devices, methods, network components and communication systems are provided to couple an application index in a flexible way to an application running on a mobile device in order to enable management of access requests requiring the same quality of service (QoS).
摘要:
There is provided a method that relates to the setting up and/or maintaining of a connection between a machine-to-machine (M2M) device and a mobile communication network. In order to be able to adapt the connection management to the requirements of the M2M device, the M2M device may transmit an indication that it is an M2M device to the mobile communication network. At least one network node of the mobile communication network controls the setting up and/or the maintaining of the connection based on the indication. The network node may route a request for setting up the connection to a further network node based on the indication.
