Valid algorithms are XOR # (xor) and MILENAGE (mil) # Key: UE's key, where other keys are derived from. Ignored by the HSS # IMSI: UE's IMSI value # Auth: Authentication algorithm used by the UE.
csv to store UE's information in HSS # Kept in the following format: "Name,Auth,IMSI,Key,OP_Type,OP,AMF,SQN,QCI,IP_alloc" # Name: Human readable name to help distinguish UE's. If your handset supports “Smart 5G”, disable this option as it may force the handset to 4G and activate roaming. On some handsets, when using a test USIM, you may need to activate 5G NR using *#*#4636#*#*. If possible, using a shielded box and configuring the network with a commercial carrier PLMN may avoid policy file issues. Carrier policy files typically don’t include test network PLMNs, so setting a test PLMN may result in 5G being disabled. Many 5G handsets may contain a carrier policy file that may limit 5G capabilities of the phone based on the PLMN of the USIM (first 6 digits of IMSI). Check the supported band combinations for your handset using this webpage``.Īs a consequence, we suggest using FDD bands for both LTE and NR carrier, such as band 20 for LTE and band n3 for NR.īoth bands are supported by the OnePlus 5G Nord used in this appnote.īesides the restrictions originating from the baseband hardware there are a few other pitfalls that may or may not allow a phone to connect to a 5G network.
However, all phones we’ve tried with cannot support 15 kHz on this band. Unfortunately, this limits the band combinations that can be used with COTS phones, as not all combinationsįor example, NR band n78 that is used in most European deployments to date (using 30 kHz SCS), in theory, also supports 15 kHz SCS. One of the current limitations of srsRAN is that both LTE and NR carrier have to use the same subcarrier spacing (SCS) of 15 kHz.
