  • Publication number: 20220070652
    Abstract: Presented herein are techniques associated with replicating an OpenRoaming™ policy federation in a Third Generation Partnership Project (3GPP) network environment. For example, techniques herein provide a roaming policy federation architecture for a 3GPP network environment. In one example a method is provided that may include encoding a multi-bit roaming policy for an identity provider within a plurality of multi-bit 3GPP broadcast identifiers in which the multi-bit roaming policy includes bit-wise roaming policy information for the identity provider. The method may further include configuring the plurality of multi-bit 3GPP broadcast identifiers for a mobile device associated with the identity provider. In one instance, detecting, by the mobile device, at least one multi-bit 3GPP broadcast identifier of the plurality of multi-bit broadcasting identifiers being broadcast by a visited radio access network triggers the mobile device to perform an authentication with the identity provider.

  • Publication number: 20220060893
    Abstract: Presented herein are techniques to facilitate delivering standalone non-public network (SNPN) credentials from an enterprise authentication server to a user equipment (UE) using an Extensible Authentication Protocol (EAP) process. In one example, a method may include determining, by an authentication server of an enterprise, that a UE for the enterprise is to receive credentials to enable the UE to connect to a SNPN of the enterprise in which the determining is performed based, at least in part, on connection of the UE to an access network that is different than the SNPN for the enterprise; and performing an authentication process with the UE by the authentication server in which the authentication process includes providing the credentials to the UE via a first authentication message and obtaining confirmation from the UE via a second authentication message that indicates successful provisioning of the credentials for the UE.

  • Patent number: 11202236
    Abstract: In one illustrative example, a user plane (UP) entity for use in a mobile network may receive a data packet from a user equipment (UE) operative to communicate in one or more sessions via a serving base station (BS) (e.g. eNB or gNB) of the mobile network. The UP entity may detect, in a header (e.g. SRH) of the data packet, an identifier indicating a new serving BS or session of the UE. The identifier may be UE- or BS-added data (e.g. iOAM data) that is inserted in the header by the UE or BS. In response, the UP entity may cause a message to be sent to an analytics function (e.g. a NWDAF) to perform analytics for session or flow migration for the UE.

  • Patent number: 11202276
    Abstract: In one example, a control plane entity obtains an indication that a User Equipment (UE) has entered an idle mode. The control plane entity sets a routing locator corresponding to the UE to cause the control plane entity to trigger a paging request toward the UE to prompt the UE to transition from the idle mode when a first network node obtains a downlink packet destined for the UE. The control plane entity obtains a notification that the first network node has obtained the downlink packet and initiates the paging request toward the UE. The control plane entity updates the routing locator corresponding to the UE to cause the first network node to transmit further downlink packets destined for the UE toward a second network node configured to handle traffic on behalf of the UE.

  • Patent number: 11153784
    Abstract: A control plane of a network, including radios of a radio access network controlled by the control plane and user plane functions controlled by the control plane, establishes first and second protocol data unit (PDU) connections each to handle the same flows of traffic for ultra-reliable low latency communications (URLLC) from user equipment to a data network through first and second source radios, respectively. Due to mobility of the user equipment, the control plane relocates the flows from the first and second source radios to first and second target radios, respectively. To relocate the flows, the control plane receives from the first target radio a notification that identifies flows that cannot be activated on the first target radio. In response to the notification, the control plane commands the first target radio to prioritize the flows that cannot be activated above remaining ones of the flows.

  • Patent number: 11128988
    Abstract: In one illustrative example, a mobility node (e.g. an SMF) may receive a message which indicates a request for creating a session for a user equipment (UE). A user plane function (UPF) instance for the session may be selected based on a set of parameters. The set of parameters may include one or more location(s) of one or more multi-access edge computing (MEC) resources and applications of interest for the UE. Location data associated with the MEC resources and applications may be determined from server addresses obtained from UPF processing of domain name server (DNS) queries associated with the applications. In preferred implementations, the server addresses are client subnet location-dependent server addresses obtained from client subnet-based DNS queries. The server addresses or location data derived therefrom may be regularly submitted to the SMF for improved UPF selection based on locations of MEC resources and applications.

  • Patent number: 11082820
    Abstract: A service interface template for an enterprise mobile service of a mobile network may be provided for use by an enterprise. The service interface template may involve an API at an API endpoint for enterprise exposure and control over at least a subset of mobile service functions of the mobile network for use in relation to a plurality of UEs of the enterprise. The API may be defined by API request types to perform operations in relation to resources of a data store. The resources may include a collection of selectable parameter indication elements corresponding to selectable parameter indications for use in provisioning mobile service functions. A backend interface function may be provided for the API endpoint, to cause the provisionable mobile service function to be provisioned and/or executed with provisionable parameters corresponding to a selected one of the selectable parameter indications received via the API endpoint.

  • Patent number: 11006328
    Abstract: End marker functionality may be provided in mobile networks having mobile user planes configured with segment routing for IPv6 (SRv6), especially suitable for 5G network migration. For example, a base station may receive an SRv6 control message from a user plane function (UPF) which carries data traffic of a data session for the UE. The base station may perform a function associated with a segment identifier (SID) identified in a segment routing header (SRH) of the SRv6 control message. The function may be an end marker handling function associated with an end marker SID. Performing the end marker handling function may cause the base station to generate a tunneling protocol message (e.g. according to GPRS tunneling protocol or GTP) comprising an end marker message and send the tunneling protocol message comprising the end marker message for receipt by the target base station.
