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: Wireless fidelity (Wi-Fi) access points (APs) can advertise their support of both OMA-DM and SOAP-XML protocols by including protocol capability information in a broadcast or probe response message. The protocol capability information can include an OSU method list subfield that indicates that the Wi-Fi AP supports both OMA-DM and SOAP-XML protocols. The broadcast message may be an Access Network Query Protocol (ANQP) message, a beacon message, or some other generic advertisement services (GAS) message. Wi-Fi APs can also specify which WLAN type is preferred by a network operator by including a WLAN access type indication in a broadcast or probe response message. The WLAN access type indication may specify that a network operator prefers a passpoint, non-passpoint, vendor specific WLAN. The WLAN access type indication may be included in an access network discovery and selection function (ANDSF) management object (MO).

Abstract: An embodiment of the disclosure includes a method including providing a network function virtualization (NFV) capacity for a plurality of virtual network functions (VNFs) on a computing platform. A network function virtualization management function creates at least one VNF to operate on the computing platform to perform a network function. Each of the VNFs has a definition comprising a plurality of parameters. At least one of the parameters is a capacity indication relative to a capacity of the network function for the respective VNF.

Abstract: An embodiment method for session handling for a connection between an UE and a network includes establishing, at a first distributed EPC, user and IP sessions over the connection through the first distributed EPC. The first distributed EPC includes a first PGW at which the IP session is anchored. The method also includes holding original IP resources and releasing original connection resources for the sessions at the first distributed EPC when the UE moves beyond the first distributed EPC to a second distributed EPC. The method then establishes a tunnel between the first PGW and a second PGW for the second distributed EPC. The tunnel utilizes the original IP resources and new connection resources at the second distributed EPC. The method then routes data from the tunnel, through the first PGW, and to the network.

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.
