1. A method for managing service calls across a network, the method comprising:
- retrieving, by a global source routing engine (SRE) and from a network repository function (NRF), a list comprising network functions (NFs) and endpoint addresses associated with respective NFs, the global SRE comprising a forwarding table;
storing, in the forwarding table, the retrieved list;
transmitting, by the global SRE and to a target SRE, a portion of the list, a portion of the list related to a network slice for which the target SRE is responsible;
receiving, by the target SRE and from an access function (AMF), a request for slice information, the request for slice information including a user equipment (UE) identifier; and
providing, by the target SRE and to the AMF, a response including the slice information for attaching the UE to a network slice identified by the slice information.

Abstract
Systems, methods, and computer-readable media for managing service calls over a network may include a signal routing engine with a maintained forwarding table for various network functions and micro-services in a services back end for the network. The signal routing engine can include a call conversion service for converting REST API calls to an internal network call protocol for increasing network function processing speeds, decreasing bandwidth usage, and improving network responsiveness and manageability.

8. A system for managing service calls across a network, the system comprising:
-
a global source routing engine (SRE) comprising a forwarding table; a network repository function (NRF) in communication with the global SRE, the global SRE retrieving from the NRF a list comprising network functions (NFs) and endpoint addresses associated with respective NFs; a target SRE in communication with the global SRE, the global SRE transmitting to the target SRE a portion of the list related to a network slice for which the target SRE is responsible; and an access function (AMF) in communication with the target SRE, the target SRE receiving from the AMF a request for slice information, the request for slice information including a user equipment (UE) identifier; wherein the target SRE provides to the AMF a response including the slice information for attaching the UE to a network slice identified by the slice information. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer readable medium comprising instructions that, when executed by one or more processors configured for network management, cause the one or more processors to:
-
retrieve, by a global source routing engine (SRE) and from a network repository function (NRF), a list comprising network functions (NFs) and endpoint addresses associated with respective NFs, the global SRE comprising a forwarding table; store, in the forwarding table, the retrieved list; transmit, by the global SRE and to a target SRE, a portion of the list, a portion of the list related to a network slice for which the target SRE is responsible; receive, by the target SRE and from an access function (AMF), a request for slice information, the request for slice information including a user equipment (UE) identifier; and provide, by the target SRE and to the AMF, a response including the slice information for attaching the UE to a network slice identified by the slice information. - View Dependent Claims (16, 17, 18, 19, 20)
