maxSDUsize

Validations ASN.1 Parent Types

The maximum size of a Service Data Unit (i.e. packet size) applicable to a UMTS GPRS connection.

Derivation: 

UMTS item QoSMaxSDUSize  (3G 32.015).

Conditionality: 

Mandatory within groups

                                UMTS Quality Of Service Requested

                                UMTS Quality Of Service Used.

Values:

The maximum SDU size is encoded in a single hexadecimal octet. By interpreting this hexadecimal octet as an unsigned integer n, the maximum SDU size s  applicable to the PDP context can be calculatd as follows:

                0 < n £  150          n * 10 octets         (0 < s £  1500)

                 n = 151                 1502 octets

                 n = 152                 1510 octets

                 n = 153                 1520 octets

The value n = 0 indicates the subscribed  Maximum SDU Size (only applicable to UMTS Quality Of Service Requested), all other values are reserved.
