Abstract: A system to distinguish internal network routing issues within a user plane function (UPF) from external routing issues via multi-domain system (DNS) servers probing is disclosed. The system determines latency in communication between a given UPF and each of a plurality of DNS servers. The system compares each latency with a threshold latency value. If it is determined that each of the latencies in communication between the UPF and each DNS server is more than the threshold latency values, the system may determine that there is an internal network routing issue at the UPF that caused the high latencies. If it is determined that a latency in communication between the UPF and a particular DNS server is more than the threshold latency value, the system may determine that the latency is caused by a network routing issue at the particular DNS server—which is external to the UPF.

Abstract: A disclosed method may include (i) implementing, within a cloud computing platform, a hierarchical quality-of-service policy that includes a parent quality-of-service sub-policy in relation to a child quality-of-service sub-policy, (ii) receiving telecommunication traffic as part of a cellular service platform implemented through the cloud computing platform, and (iii) applying, within the cloud computing platform, the hierarchical quality-of-service policy to the telecommunication traffic to satisfy a predetermined level of quality of service.

Abstract: An apparatus is communicatively coupled to a plurality of databases in a service-based architecture and comprises a memory and a processor. The memory stores multiple configuration commands. The processor is configured to generate a request to establish a communication session in which a network component accesses a first database and a second database based at least in part upon a configuration command of the configuration commands. The network component exchanges connectivity signals with the first database and the second database. The first database provides database operations in response to the connectivity signals exchanged with the network component. The first database reports to the second database that the database operations are provided. The processor is further configured to, in response to determining that the communication session between the network component and the first database is lost, maintain the communication session to access the second database.

Abstract: An apparatus is configured to communicate with multiple network components in a service-based architecture and comprising a memory and a processor. The memory stores multiple configuration commands; multiple local provisioning parameters; and a configuration script. Each local provisioning parameter is a backup copy of a corresponding configuration command. The processor is configured to generate a request to establish a communication session between a first network and a second network component. Further, the processor is configured to establish the communication session between the first network component and the second network component based at least in part upon a configuration command; determine that the communication session is lost based at least in part upon identifying an interruption in the communication session; and execute the configuration script to instruct the first network component to establish a backup communication session based at least in part upon a local provisioning parameter.

Abstract: An apparatus is configured to communicate with multiple network components in a service-based architecture and comprises a memory and a processor. The memory stores multiple configuration commands. The processor is configured to generate a request to establish a communication session between a first network component, a second network component, and a third network component. The first network component exchanges connectivity signals with the second network component and the third network component. The second network component performs first plurality of session operations in response to the connectivity signals exchanged with the first network component. The second network component reports to the third network component that the first session operations are performed.

Abstract: A disclosed method may include (i) maintaining a database that maps cellular reference link types to geographic hubs that include a respective cellular network node connected through a respective cellular reference link type, (ii) cycling through the database, within a portion of the database for a specific cellular reference link type, to perform a ping operation from each respective geographic hub mapped to the specific cellular reference link type, and (iii) displaying, through a graphical user interface, results to an administrator indicating which ping operations from the cycling through the database indicated a failure such that the administrator is enabled to perform a remediation operation. Various other systems and computer-readable mediums are further disclosed.

Abstract: A disclosed method may include (i) establishing an Internet Protocol Multimedia Subsystem instance, (ii) aggregating, within the Internet Protocol Multimedia Subsystem instance, multiple distinct cloud native functions that are associated with the Internet Protocol Multimedia Subsystem instance such that the multiple distinct cloud native functions communicate through a single Internet Protocol address, and (iii) directing outbound communications from the multiple distinct cloud native functions associated with the Internet Protocol Multimedia Subsystem instance through the single Internet Protocol address. Various other systems and computer-readable mediums are further disclosed.

Abstract: A disclosed method may include (i) disposing a network access table gateway between a multimedia service center within a cellular service network and a telecommunications server of an external wireless network provider that has partnered with the cellular service network, (ii) receiving, at the network access table gateway, a network packet that was sent from the telecommunications server of the external wireless network provider and that is directed to a public Internet Protocol address of the network access table gateway, and (iii) routing, by referencing a network access table of the network access table gateway, the network packet to a destination within the cellular service network. Related systems and computer-readable mediums are further disclosed.

Abstract: A disclosed method may include (i) obtaining, by a home cellular network service provider from a roaming cellular network service provider, a list of identifiers indicating respective ranges of Internet Protocol addresses that are targets for remote packet data nodes of the roaming cellular network service provider, (ii) for each respective server, in a list of respective servers that the home cellular network service provider assigned to respective geographic hubs, pinging through an on-demand cloud computing platform each usable Internet Protocol address indicated by each respective identifier in the list of identifiers, and (iii) discovering, by the home cellular network service provider, in response to the pinging, which Internet Protocol addresses indicated a healthy remote packet data node of the roaming cellular network service provider.
