Description |
The early classmark sending control (ECSC) specifies whether the MSs in a cell use early classmark sending. For details, see GSM Rec. 04.08.After a successful immediate assignment, the MS sends additional classmark information to the network as early as possible. The CM3 (classmark 3) information contains the power information of each band of multi-band MSs. In the inter-band handover, power class must be correctly described. When paging is made or the BA2 table is sent between different bands, the CM3 message must be known. For dual-band MSs, if ECSC is set to No, the MSC sends a CLASSMARK REQUEST message after the MS reports an EST IND message. The MS then reports the CLASSMARK UPDATE message. The connection time of the MS is affected. |
