  • Patent number: 10313208
    Abstract: The disclosure relates to a method of resource allocation for supporting communications with a wireless device is provided. The method is performed in a network element of a wireless communication network. The method comprises differentiating (2710) between synchronous network functions and asynchronous network functions. The synchronous and asynchronous network functions are associated with the provision of communication services to the wireless device. The synchronous network functions have requirements on processing timing which are strictly dependent on timing of a radio link used for communicating with the wireless device. The asynchronous network functions have requirements on processing timing not strictly dependent on the timing of the radio link. The method also comprises allocating (2720) resources of the wireless communication network for the instantiation of a first network function based on whether the first network function is synchronous or asynchronous.

  • Publication number: 20190045352
    Abstract: Handling of UE capability information in a mobile telecommunications network wherein an eNodeB receives information regarding the UE capability information from the UE and stores the information. The eNodeB sends the UE capability information to the EPC, i.e., to an MME, which receives and stores the UE capability information. When the UE transits from idle to active state, does an initial attach, or when a part of the UE capabilities have changed, it sends a message to the eNodeB regarding the update. The eNodeB forwards the message to the MME, which sends a response associated with the previously stored UE capability information to the eNodeB. The eNodeB decides whether the UE capabilities stored in the MME is up-to-date based on the message from the UE and the response from the MME. If the UE holds updated UE capabilities the eNodeB can request updated UE capability information from the UE.
