In the prior art, the 5G network architecture mode is divided into NSA (Non-standby dependent networking) and SA (standby independent networking). NSA adopts a double connection mode, the 5G NR control plane is anchored to the 4G LTE, and a 4G core network EPC is utilized; for SA, the 5G NR directly accesses the 5G core network, which is no longer dependent on 4G, and is a complete independent 5G network.
In a New Radio (NR) of 5G, a system Bandwidth, i.e., a Bandwidth of one carrier, may become very large (e.g., 200MHz or 400MHz), and some terminals have limited capabilities and cannot support the large Bandwidth, so that the network device configures a BWP (Bandwidth Part, BWP) to the terminal, i.e., a portion of the system Bandwidth, e.g., 20MHz, and the terminal may communicate with the network device over the BWP.
Under NSA networking, a terminal antenna needs to be connected with two wireless access technologies of LTE and NR; under the SA networking, only NR one wireless access technology is connected to the terminal antenna. When SABWP conversion is performed in a 5G network, terminal equipment needs to be tested; the current test of the terminal equipment mainly comprises the following steps: radio frequency index testing, protocol testing, radio resource management testing and other testing. The protocol test comprises a consistency test, a performance test, an interoperability test and a robustness test. Conformance testing is an important aspect of protocol testing and is the basis for performance testing, interoperability testing, and robustness testing.
In the existing terminal protocol consistency test method, when the result of the inconsistency of the terminal protocol can only be output when the abnormity occurs in the test process, the verification of the reason of the inconsistency of the terminal protocol can not be realized, and thus the overall efficiency of the terminal protocol consistency test is reduced.
