CSCzn16621, CSCzn16622 - MME needs to support non-3gpp-to-LTE handover
Feature Changes
Unoptimized Non-3GPP Handover Support
This feature provides MME support for Non-3GPP to EUTRAN and EUTRAN to Non-3GPP un-optimized handovers.
These include the LTE-eHRPD handover scenarios in sections 8.2.1.1 and 8.2.1.2, and 8.2.2 and 8.2.3 of 3GPP TS
23.402-910.
These include the LTE-eHRPD handover scenarios in sections 8.2.1.1 and 8.2.1.2, and 8.2.2 and 8.2.3 of 3GPP TS
23.402-910.
No configuration is required to enable this functionality on the MME.
Note:
PDN Connectivity request should contain Request Type as HANDOVER.
P-GW is selected only through HSS-provided P-GW address or FQDN (MIP6-Info), with P-GW allocation type
as static always.
In the case of multiple PDN connectivity during handover from non-3gpp access to EUTRAN, the ESM PDN
connectivity message from UE is transported via S1AP Uplink NAS transport. All other such PDN
connectivity requests shall be rejected.
connectivity requests shall be rejected.
