Section: 10.5.6.5 Quality of service
Content: The purpose of the quality of service information element is to specify the QoS parameters for a PDP context. The QoS IE is defined to allow backward compatibility to earlier version of Session Management Protocol. The quality of service is a type 4 information element with a minimum length of 14 octets and a maximum length of 22 octets. The QoS requested by the MS shall be encoded both in the QoS attributes specified in octets 3-5 and in the QoS attributes specified in octets 6-14. In the MS to network direction and in the network to MS direction the following applies: - Octets 15-22 are optional. If octet 15 is included, then octet 16 shall also be included, and octets 17-22may be included. - If octet 17 is included, then octet 18 shall also be included and octets 19-22 may be included. - If octet 19 is included, then octet 20 shall also be included, and octets 21 and 22 may be included. - If octet 21 is included, then octet 22 shall also be included. - A QoS IE received without octets 6-22, without octets 14-22, without octets 15-22, without octets 17-22, without octets 19-22 or without octets 21-22 shall be accepted by the receiving entity. NOTE: This behavior is required for interworking with entities supporting an earlier version of the protocol, or when the Maximum bit rate for downlink or for downlink and uplink is negotiated to a value lower than 8700 kbps. The quality of service information element is coded as shown in figure 10.5.138/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ]  and table 10.5.156/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ] .

The coding is identical to that of the Maximum bit rate for downlink (extended 2). If the sending entity wants to indicate a Maximum bit rate for uplink higher than 10 Gbps, it shall set octet 21 to "11110110", i.e. 10 Gbps, and shall encode the value for the maximum bit rate in the extended quality of service information element specified in subclause 10.5.6.5B. The network shall map all other values not explicitly defined onto one of the values defined in this version of the protocol. The network shall return a negotiated value which is explicitly defined in this version of the protocol. The MS shall map all other values not explicitly defined onto the maximum value defined in this version of the protocol. Guaranteed bit rate for uplink (extended-2), octet 22 This field is an extension of the Guaranteed bit rate for uplink in octet 18. The coding is identical to that of the Guaranteed bit rate for downlink (extended-2). If the sending entity wants to indicate a Guaranteed bit rate for uplink higher than 10 Gbps, it shall set octet 22 to "11110110", i.e. 10 Gbps, and shall encode the value for the guaranteed bit rate in the extended quality of service information element specified in subclause 10.5.6.5B. The network shall map all other values not explicitly defined onto one of the values defined in this version of the protocol. The network shall return a negotiated value which is explicitly defined in this version of the protocol. The MS shall map all other values not explicitly defined onto the maximum value defined in this version of the protocol.
