  • Patent number: 10972552
    Abstract: Aspects of the disclosure provide a system and method used for allowing a path selection or reselection (hereby (re)selection). In some embodiments data packets for a session between a UE and an application system (AS) can utilize a pre-established user plane path between the AS and an access node (AN) which serves the UE. This can allow for faster session set-up times as a new user plane (UP) path need not be established for every new session if existing UP paths can be utilized. Some embodiments allow an application aware (re)selection of the user plane.

  • Patent number: 10973011
    Abstract: A mobile terminal in a wireless communication network may be one of several modes of operation. When in an idle mode, the mobile terminal may avoid a lengthy random access procedure normally associated with responding to a page from a base station, if the base station includes in the page an indication of a resource that the mobile terminal may utilize when responding to the page. Additionally, the mobile terminal may transmit an efficient location update MAC header to a base station, whether prompted to by a page from the base station or not. Furthermore, without leaving the idle mode or a sleep mode, the mobile terminal may exchange short data burst messages with a base station.

  • Patent number: 10880176
    Abstract: Aspects of the disclosure provide architectures, methods and systems that will allow reconfigurability of the network to suit the needs of various parties. Accordingly, some embodiments provide a controllable open operation environment. In such an environment, there can be a decoupling of various network aspects which would be conventionally be under the span of control of a service provider, allowing for each aspect to be provided by a different entity. For example, infrastructure can be provided separately from the provider of network services to subscribers and/or from the provider of slices and/or from the provider of NOS services. For example an infrastructure provider can provide infrastructure used by a slice provider to provide network slices to virtual network providers which provide services to end customers. Generally speaking, SONAC-Com is responsible for the composition of slices and manages resources at the slice level. SONAC-Op is responsible for the operation of slices.
