Telecommunication service models determine the delivery of communication services. AGILITY uses the service models described on this page to run predictions and provide network analysis. For a comprehensive list of all protocols, and interfaces that AGILITY supports for these models, see Model Coverage Tables /wiki/spaces/~712020272113beb61f46609e5721d6521a154c/pages/3205956647.

4G-5G NSA Connectivity

4G-5G NSA connectivity represents an interim step in the evolution of mobile networks, allowing for the introduction of 5G benefits while leveraging the existing 4G infrastructure for a smoother transition.

...

• Users with 5G-enabled devices can experience faster data speeds and lower latency when connected to 5G cells, while still maintaining connectivity through 4G when 5G is not available.

• It allows for a gradual transition to full 5G standalone deployments as the 5G infrastructure is expanded and upgraded.

4G-5G-NSA Data

4G-5G NSA (Non-Standalone) data embodies a hybrid approach, leveraging the strengths of both 4G and 5G networks to provide users with improved data connectivity, speed, and latency while paving the way for a more comprehensive 5G standalone future.

The 4G-5G-NSA model includes the following captures required from NE interfaces:​

...

eNodeB: X2

...

gNodeB: X2 (for 5G NSA configuration)

...

• MME: S1_MME, S11, S6a

• S-GW: S11, S5c

• P-GW: S5c, Gx, Gy

• PCRF: Sy

4G Data

4G data is the data connectivity and communication services facilitated through a 4G network architecture.

The 4G Data model includes captures of data calls from:​​

• MME: S1_MME, S11, S6a

• S-GW: S1u, S5c, S5u​

• P-GW: S5c, S5u, Gm, Gy, Gx​

• OCS: Gy, Sy, Ro​

• HSS: S6a, Cx, Sh​

5G-SA Mobility

5G-SA (Standalone) data is the data connectivity and communication services facilitated through a fully independent 5G network architecture. Unlike 4G-5G NSA (Non-Standalone) deployments that rely on existing 4G infrastructure, 5G-SA operates with a standalone core network and radio access network (RAN).

The 5G-SA model includes captures of data calls from:5G-SA (Standalone) mobility is the mobile communication capabilities provided by a fully independent 5G network architecture. In the context of mobility, this encompasses the seamless and advanced connectivity solutions designed to cater to the dynamic and mobile nature of devices and users.

The 5G-S model includes captures of handover calls from:​

• gNodeB: Xn, Xnc, N2​

• O-CU: Xn, Xnc, N2 (O-Ran scenarios)​

• AMF: N2​

• UPF: N3, N6​

• 5G SA​

• Xn based handover (handled directly between gNodeB’s)​*(pending)

• N2 based handover (Coordinated by AMF)​

5G - SMS: SMS over NAS-5GS

SMS over NAS-5GS allows 5G SA users to send SMS messages through the 5G core network. The AMF sends and receives SMS messages from the UE over the N1 interface, which carries NAS-5GS messages. The 5G core entities, AMF and SMSF, provision services for each other to enable the transfer of SMS over NAS-5GS.

The SMS over NAS-5GS Model captures:

• UE: N1​

• AMF: N2, HTTP2 SBA services​

• SMSF: HTTP2 SBA services

• UDM: HTTP2 SBA services

4G - SMS: SMS over NAS-EPS

SMS over NAS-5PS allows 4G users to send SMS messages through the 4G core network. The MME sends and receives SMS messages from the UE over the S1 interface, which carries NAS-EPS messages. The 4G core entities, MME and MSC, provision services for each other to enable the transfer of SMS over NAS-EPS.

The SMS over NAS-EPS Model captures:

• MME: S1_MME, S11, SGs

• S-GW: S1u, S5c, S5u​

• P-GW: S5c, S5u, Gm, Gy, Gx​

• OCS: Gy, Sy, Ro​

• HSS: S6a, Cx, Sh​

4G - E911

E911 is a service that enables emergency operators to provide assistance to users calling 911. E911 calls are directed to emergency responders such as police, fire, and rescue departments, collectively known as Public Safety Answering Points (PSAPs). The call setup process is similar to VoLTE but includes additional components like the Emergency S-CSCF, which routes the calls to specific servers that use geo-location to assist emergency response.

The E911 Model captures:

• MME: S1_MME, S11, SLs​

• S-GW: S1u, S5c, S5u​

• P-GW: S5c, S5u, Gm, Gy, Gx​
