  • Publication number: 20190251274
    Abstract: Methods and apparatuses are described for enterprise access control governance in a computerized information technology (IT) architecture. A server generates a first vector space, each node in the first space representing a user of resources in the IT architecture and including attributes of the user. The server generates a second vector space, each node in the second space representing an entitlement to access resources in the IT architecture and including attributes of the entitlement. The server creates an entitlement utility matrix by mapping nodes in the first space to nodes in the second space. The server determines a set of recommended entitlements for a plurality of users based upon the utility matrix. The server determines a discrepancy between the set of recommended entitlements for a first user and a set of existing entitlements for the first user and adjusts the set of existing entitlements based upon the discrepancy.

  • Publication number: 20180279161
    Abstract: The present disclosure relates to a QoS guarantee method. In one example method, a control plane gateway obtains a QoS parameter. The QoS parameter comprises an allocation/retention priority (ARP) and a QoS class identifier (QCI). The control plane gateway maps the QoS parameter to QoS guarantee information. The QoS guarantee information comprises a differentiated services code point (DSCP) parameter. The control plane gateway sends the QoS guarantee information to a user plane gateway. The QoS guarantee information is to be used by the user plane gateway for QoS marking.

  • Publication number: 20180255481
    Abstract: Embodiments of the present disclosure disclose example service flow transmission methods and apparatus. One example method includes where a first gateway device determines a target service currently performed by UE, performs a bearer processing operation to obtain a target bearer corresponding to the target service, and binds a service flow of the target service to the target bearer. The first gateway device anchors the target bearer to a target gateway, and implements, by using the target gateway, service flow transmission between the UE and a network that corresponds to the target service. In some instances, a service flow can be bound to a bearer obtained after performing a bearer operation and the bearer can be anchored to an appropriate gateway.
