Connection configuration for Fourth Generation (4G) and Fifth Generation (5G) converged deployment may be provided. A User Equipment (UE) Usage Type (UUT) mapping may be stored, wherein the UUT mapping includes an Attribute Value Pair (AVP) for one or more UUTs. A connection to a 5G network from a 4G network may be received from a UE, wherein the connection comprises subscription information that includes a UUT the UE is subscribed to. In response to receiving the UUT, a subscriber profile for the UE in a converged packet core may be determined using the UUT mapping, and the configuration of the connection for the UE may be established based on the determined subscriber profile.

A method is provided for use in a network that includes a plurality of user plane functions that perform processing of user plane traffic sessions from one or more mobile wireless user devices. The method includes periodically monitoring resource utilization of the plurality of user plane functions to estimate a resource utilization level of respective user plane functions. Based on the periodically monitoring, the method further includes storing for the respective user plane functions a resource utilization level indicator for each of the respective user plane functions according a resource utilization level of the respective user plane functions. User plane traffic sessions for a given tracking area are re-assigned (moved) among the plurality of user plane functions based on the resource utilization level indicators for the respective user plane functions to achieve a desired quality of experience for the user plane traffic sessions.

Intelligent and optimal resource selection within a network slice

The present technology is directed to generating a common Border Gateway Protocol (BGP) attribute, for example, BGP-Slice Identifier (ID) for a specific network slice and stitching the network slice across one or more domains to realize end-to-end slicing. The present technology can generate BGP ID for a specific network slice spanning a plurality of domains and map domain-specific attributes associated with sub-slices of the specific network slice in different domains of the plurality of domains to the BGP ID. The present technology can further facilitate distribution of the mapping of the domain-specific attributes to the BGP ID across the plurality of domains for stitching the sub-slices together from the domain-specific attributes based on the BGP ID to stitch the specific network slice across the plurality of domains. Furthermore, the present technology can identify a configuration error in the mapping of the domain-specific attributes and the BGP ID and transmit a feedback informing the existence of the error for performing remedial measures.

Techniques and mechanisms for Fifth Generation (5G) system (5GS) failure detection monitoring of an application or control function in a network for efficient restoration of service are described. The network may be an Internet Protocol (IP) Multimedia Subsystem (IMS) network, and the voice or data service may be an IMS service that utilizes Session Initiation Protocol (SIP) signaling. The application or control function may be a Proxy-Call Session Control Function (P-CSCF) of the IMS network. In some implementations, the procedure may involve a session management function (SMF) programming of a user plane function (UPF) for UPF monitoring of the P-CSCF, using a ping procedure or health check procedure (e.g. for 3GPP Pre-Release 16). In other implementations, the procedure may involve the SMF monitoring of a P-CSCF via a Network Function (NF) Repository Function (NRF) (e.g. for 3GPP Release 16).

Techniques are provided to communicate the serving Radio Access Network (RAN) element information to the packet core network to enable operators to provide differential treatment for fifth generation (5G) subscribers. The techniques presented herein fill these gaps and help drive faster adoption of Dual Connectivity New Radio (DCNR) subscribers by service operator to offer customized policy and quota management to address different business requirements in the 5G Non-Stand Alone (NSA) architecture.
