Abstract
End marker functionality may be provided in mobile networks having mobile user planes configured with segment routing for IPv6 (SRv6), especially suitable for 5G network migration. For example, a base station may receive an SRv6 control message from a user plane function (UPF) which carries data traffic of a data session for the UE. The base station may perform a function associated with a segment identifier (SID) identified in a segment routing header (SRH) of the SRv6 control message. The function may be an end marker handling function associated with an end marker SID. Performing the end marker handling function may cause the base station to generate a tunneling protocol message (e.g. according to GPRS tunneling protocol or GTP) comprising an end marker message and send the tunneling protocol message comprising the end marker message for receipt by the target base station.
