Abstract: A Virtual Network Function Descriptor (VNFD) parameter may include subfields that allow a management entity to determine whether the VNFD parameter can be updated. The subfields may include a write-ability subfield that indicates whether the VNFD parameter is a dynamic/configurable VNFD parameter or a fixed/static VNFD parameter. The VNFD parameter may also include an access permission subfield that indicates which entities are authorized to modify/update the VNFD parameter. The VNFD parameter may also include an administrative priority subfield that indicates a priority of an entity that set an attribute of the VNFD parameter. The VNFD parameter may also include a constraints subfield that indicates one or more conditions that are required to occur in order for the VNFD parameter to be updated.

Abstract: Systems and methods for network function virtualization (NFV) resource management are disclosed that include receiving, by a network functions virtualization orchestrator (NFVO), a reuse requirement for a first network service (NS) and determining, by the NFVO, that at least one constituent virtual network function (VNF) instance in the first NS is retainable for reuse in a second NS according to the reuse requirement when the first NS is to be terminated. In some embodiments, these systems and methods also include retaining, by the NFVO, the at least one constituent VNF instance in the first NS for reuse in the second NS.

Abstract: Systems and methods are disclosed for resource management by a network functions virtualization orchestrator (NFVO). These systems and methods include embodiments whereby a NFVO obtains requirements for a network service lifecycle management (LCM) operation, determines a delegating granting decision for a virtualized network function (VNF) manager (VNFM) associated with the network service LCM operation in accordance with the requirements for the network service LCM operation that grants a permission for the VNFM to perform multiple VNF LCM operations under one or more constraints, and sends the delegating granting decision to the VNFM.

Abstract: Internet protocol (IP) address allocations in distributed EPC networks can be published to an IP address registry maintained at the central EPC entity in order to facilitate the routing of authentication authorization, and accounting (AAA) signaling of third party networks throughout the distributed EPC network architecture. The address allocations can be published directly to an address registry maintained by the central EPC entity, or indirectly via a cloud management server. Additionally, latencies associated with UE authentication in distributed EPC network architectures can be mitigated by triggering communication of the authentication or authorization profile upon reception of an update location request (ULR) message at the central EPC network entity.

Abstract: Embodiments are provided for supporting network selection for wireless networks and network service providers/operators. The embodiments include procedures that integrate wireless network and service provider/operator selection policies and methods. In an embodiment, the UE obtains a network selection policy from a network, and hence generates a list of candidate wireless networks according to the network selection policy. The UE then selects from the list a wireless network to connect to according to a service provider selection policy. Such procedures improve Access Network Discovery and Selection Function (ANDSF) based wireless local area network (WLAN) selection with service provider selection capability. The procedures also collaborate ANDSF based policy and existing I-WLAN selection, and resolve conflicts between 3GPP WLAN selection and ANDSF policy for WLAN selection.
