Hi there, Is there a way to get Information out of the 3GPP-GPRS-Negotiated-QoS-profile? The Attribute is defined in the dictionary as: ATTRIBUTE 3GPP-GPRS-Negotiated-QoS-profile 5 string The Value of a String might be: 99-0B811F7396878774010000 To get the encapsulated "Traffic Class", I will need the most left 3 bits of the first '7' of the string. It would be 7 --> 0111 --> 011 --> 3 Is there a function available, to do this? Following the complete Attribute: AVP: l=33 v=3GPP(10415) t=3GPP-GPRS-Negotiated-QoS-profile(5): UMTS GTP QoS Profile Length: 25 UMTS GTP QoS Profile Version: 99 Hyphen separator: - 00.. .... = Spare: 0 ..00 1... = QoS delay: Delay class 1 (1) .... .011 = QoS reliability: Unack GTP/LLC, Ack RLC, Protected data (3) 1000 .... = QoS peak: Up to 128 000 oct/s (8) .... 0... = Spare: 0 .... .001 = QoS precedence: High priority (1) 000. .... = Spare: 0 ...1 1111 = QoS mean: Best effort (31) 011. .... = Traffic class: Interactive class (3) ...1 0... = Delivery order: Without delivery order ('no') (2) .... .011 = Delivery of erroneous SDU: Erroneous SDUs are not delivered ('no') (3) Maximum SDU size : 1500 octets Maximum bit rate for uplink : 1024 kbps Maximum bit rate for downlink : 1024 kbps 0111 .... = Residual BER: 1/100 000 = 1x10^-5 (7) .... 0100 = SDU Error ratio: 1/10 000 = 1x10^-4 (4) 0000 00.. = Transfer delay: Subscribed Transfer Delay (in MS to network direction) (0) .... ..01 = Traffic handling priority: Priority level 1 (1) Guaranteed bit rate for uplink: Subscribed guaranteed bit rate for uplink (in MS to network direction) (0) Guaranteed bit rate for downlink: Subscribed guaranteed bit rate for downlink (in MS to network direction) (0) Thank You.
