Abstract: Systems may establish a Session Initiated Protocol (SIP) session during a Home Subscriber Server (HSS) outage. The systems may include Network Functions (NF) that perform steps for establishing the SIP session and/or bypassing the HSS experiencing the outage. For instance, an Interrogating (I)-Call Session Control Function (CSCF) may modify a terminating message received from a User Equipment (UE) to generate a modified terminating message, and send one or more instances (e.g., forks) of the modified terminating message to one or more candidate Serving (S)-CSCFs. A particular S-CSCF of the candidate S-CSCFs may comprise the registered S-CSCF and may respond to an instance of the modified terminating message. In some embodiments, the I-CSCF may establish the SIP session by sending an instance of the modified terminating message to a designated S-CSCF. The designated S-CSCF may determine which candidate S-CSCF comprises the registered S-CSCF, for instance, by querying the candidate S-CSCFs.

Abstract: An endpoint group (EPG) can be stretched between the sites so that endpoints at different sites can be assigned to the same stretched EPG. Because the sites can use different bridge domains when establishing the stretched EPGs, the first time a site transmits a packet to an endpoint in a different site, the site learns or discovers a path to the destination endpoint. The site can use BGP to identify the site with the host and use a multicast tunnel to reach the site. A unicast tunnel can be used to transmit future packets to the destination endpoint. Additionally, a stretched EPG can be segmented to form a micro-stretched EPG. Filtering criteria can be used to identify a subset of the endpoints in the stretched EPG that are then assigned to the micro-stretched EPG, which can have different policies than the stretched EPG.

Abstract: A method, a device, and a non-transitory storage medium are described in which an island tracking area code detection and remedial service is provided. A device may detect an island tracking area code cell based on a predicted optimal tracking area code. The device calculates scores for neighbor cells and their corresponding tracking area codes based on the distances of the neighbor cells from a target cell. The device may select the predicted optimal tracking area code based on these scores. The device may use the predicted optimal tracking area code as a basis to determine whether a tracking area code assigned to the target cell is an island tracking area code cell. The device may perform a remedial measure when an island tracking area code cell is detected.
