Annex E (informative):
Comparison between call control procedures specified in 3GPP TS 24.008 and ITU-T Recommendation Q.931
This annex summarizes a comparison of the procedures for call control as specified in ITU-T Recommendation Q.931 (blue book) and 3GPP TS 24.008.
If no comment is given, it means that the procedures specified in ITU-T Recommendation Q.931 and 3GPP TS 24.008 are similar. However, it should be noted that even in such cases the procedures may be described in slightly different ways in the two documents.

Annex F (informative):
A/Gb mode specific cause values for radio resource management
See 3GPP TS 44.018 [84].
Annex G (informative):
3GPP specific cause values for mobility management
This annex describes the cause values for the mobility management procedures for non-GPRS services (MM) and GPRS services (GMM). Clauses G1 to G5 are valid for both MM and GMM. However, the following codes are applicable for non-GPRS services only:
#38 Call cannot be identified
Clause G.6 applies only for GMM procedures.
