Solver for LTE

Solver for LTE, provides functional tests of the EPC (Evolved Packet Core) in LTE networks.

Solver LTE simulates an E-UTRAN with a large number of user equipments connected, providing load and stress to the EPC network. Solver performs testing of the control plane and the user plane with various applications and traffic patterns.

Sessions can be configured and used alone, for testing of specific scenarios, or in parallel to simulate a normal usage of the network and analyse the behaviour of the EPC.

S1-MME/S1-U

S1 is a standardised logical interface between the eNodeB and the Evolved Packet Core (EPC). S1 has two "flavours", S1-MME for exchange of signalling messages between the eNodeB and the MME; (control plane), and S1-U for the transport of user datagrams between the eNodeB and the Serving Gateway (S-GW); (user plane).

Protocol Conformance S1

Control plane:

• S1-AP (ETSI TS 136 413)
• SCTP (RFC4960)

User plane:

• IPv4 (RFC 791) or Ipv6 (RFC 2460)
• UDP (RFC 768)
• GTP-U (3GPP TS 29.060)
• User data (UDP/IPv4/iPv6) (RFC 768, RFC 791, RFC 2460)

Handover

Solver LTE can simulate intrasystem handover.
