  • Publication number: 20240121740
    Abstract: In response to receiving from a requesting entity (2) a request for a connection to an entity providing a service in an edge data network (4), a first server (7) attempts to identify a second server (5) located in the edge data network (7) based on at least one selection criterion. If the second server (4) cannot be identified or is not available, the first server (7) identifies a second alternative server that is different from the second server, or identify a first alternative server that substitutes for the first server (7) for attempting to identify the second server. This can contribute, for example, to mitigating the impact of failing to discover one or more preferred edge servers for a User Equipment (UE).

  • Publication number: 20240113042
    Abstract: A microelectronic device including an isolation device. The isolation device includes a lower isolation element, an upper isolation element, and an inorganic dielectric plateau between the lower isolation element and the upper isolation element. The inorganic dielectric plateau contains an upper etch stop layer and a lower etch stop layer between the upper isolation element and the lower isolation element. The upper etch stop layer provides an end point signal during the plateau etch process which provides feedback on the amount of inorganic dielectric plateau which has been etched. The lower etch stop layer provides a traditional etch stop function to provide for a complete plateau etch and protection of an underlying metal bond pad. The inorganic dielectric plateau also contains alternating layers of high stress and low stress silicon dioxide, which provide a means of reinforcement of the inorganic dielectric plateau.

  • Publication number: 20240107481
    Abstract: Disclosed are techniques for registering a user equipment (UE) to a new access and mobility management function (AMF). When a new access and mobility management function (AMF) determines that an old AMF is disjoint AMF i.e. they are not connected, then the new AMF fetches the UE context (5GMM and SGSM context) from the old AMF via new generation radio access network (NG-RAN). The new AMF routes a Namf_Communication_UEContextTransfer request message to the old AMF to fetch the UE contexts via NG-RAN. The old AMF sends the UE contexts in the Namf_Communication_UEContextTransfer response message to the new AMF via NG-RAN. Based on the context transfers between the new AMF and the old AMF, the UE is registered to the new AMF.

  • Publication number: 20240107424
    Abstract: In response to receiving from a requesting entity (2) a request for a connection to an entity providing a service in an edge data network (4), a first server (7) attempts to identify a second server (5) located in the edge data network (7) based on at least one selection criterion. The at least one selection criterion includes a congestion state of a server located within the edge data network (4). If the second server (5) is identified, the first server (7) sends information about the second server (5) to the requesting entity (2). If the second server (5) cannot be identified, the first server (7) sends to the requesting entity (2) a rejection message indicating that the second server (5) cannot be identified. This can contribute, for example, to providing a suitable selection criterion for identifying an edge server.

  • Publication number: 20230413118
    Abstract: An exposure node (50) receives a first request for resource management for future background data transfer between an application service provider and a plurality of radio terminals (10) from a server (60) associated with the application service provider and send a second request to a policy control node (40) in response to receiving the first request. The first request includes a parameter indicating whether background data transfer not complying with a previously agreed or negotiated transfer policy should be stopped, or whether the background data transfer should continue under a charging rule different from a previously agreed charging rule. The second request includes the parameter obtained from the first request. This enables the application service provider to negotiate with the radio communication network about handling of background data transfer not complying with a previously agreed transfer policy.
