Huawei MG323 manual Delay Level Average Transmission Delay Percentile

HUAWEI MG323 GSM M2M Module
AT Command Interface Specification	Commands for Data Services

Parameter description

<cid>: numeric parameter, which indicates the index value of the PDP context; value

range: 1–3. For a TE-MT interface, this parameter is local and can be used for other commands related to the PDP context.

<precedence>: numeric parameter, which specifies the priority level.

z0 (default value): network customization parameter

z1: higher than priority levels 2 and 3; implements service commitments with high priority.

z2: higher than priority level 3; implements service commitments with medium priority.

z3: implements service commitments with low priority.

<delay>: numeric parameter, which indicates the delay level; value range: 0–4; this parameter defines the delay of SDU transmission on the GPRS network.

0 (default value): network customization parameter

When the size of SDU is 128 octets:

Delay Level	Average Transmission Delay	95 Percentile
1(Predictive)	<0.5	<1.5
2(Predictive)	<5	<25
3(Predictive)	<50	<250
4(Best Effort)	Unspecified

When the size of SDU is 1024 octets:

Delay Level	Average Transmission Delay	95 Percentile
1(Predictive)	<0.5	<1.5
2(Predictive)	<5	<25
3(Predictive)	<50	<250
4(Best Effort)	Unspecified

<reliability>: integer, which specifies the reliability level of processing uncommon data loss.

z0 (default value): network customization parameter

z1: cannot process non-real-time services and error-sensitive applications for data loss

z2: can process non-real-time services and error-sensitive applications for data loss

z3: can process non-real-time services and error-sensitive applications for data loss, GMM/SM, and SMS
