We understand that Huawei developed solutions for radio trunking into 2 versions which are B-TRUNC and 3GPP. 3GPP was developed to make sure it complies with the international standard, while B-TRUNC was china standard.

We tried to study the network architecture of both versions. Below is the network architecture, but the question is how to differentiate the B-TRUNC and 3GPP versions?

B-TRUNC Architecture

After doing detailed study, we can conclude few things between 3GPP and B-TRUNC.

1) B-TRUNC supported more hand-portable model compared to 3GPP.

2) B-TRUNC will use eCN (eCNS, eSCN) while 3GPP will use eCORE for its core equipment.

3) 3GPP version must use BTS clock while B-TRUNC is not compulsory.

4) For the OSS, 3GPP will combine both of the U2000 and the eOMC910 while B-TRUNC only use the eOMC910

5) For other interconnection devices such as transmission network (switches, routers), PTT-mic, video decoder, and interconnection gateway can be used with either for 3GPP or B-TRUNC version

Below are the detailed comparison for each product and its compatibility with either 3GPP/B-TRUNC version

Apart from supporting more handheld as compared to 3GPP, what are other advantages B-TRUNC has over 3GPP? Why China choose B-TRUNC over 3GPP?

It's more to the standard that developed by China, while 3GPP is the global standard use widely anywhere in the world

HQ has confirmed that EP820 does not support 3GPP Release 12, which includes MCPTT. Also confirmed EP720 supports 3GPP release 12
