Different L2 links are

45、n of an SABM frame in multi-frame established state.When such an event has occurred, BTS notifies BSC by sending an ERROR INDication messagecontaining the relevant cause information.Page 14GSM 08.58 version 5.10.0 Release 1996: November 1999MS BTS BSCabnormalcase ERROR IND 4 Dedicated channel manage

46、ment procedures4.1 Channel activationThis procedure is used to activate a channel at the BTS for an MS which later will be commanded to thischannel by an IMMediate ASSIGN, an ASSIGN CoMmanD, an ADDitional ASSIGNment; aNOTIFICATION, a CHANNEL RELEASE (with a Channel description) a HANDOver CoMmanD or

47、 aCONFiguration CHange CoMmanD message.In the handover case, the procedure is used between the target BSC and the target BTS to activate achannel for a subsequent handover from the old BTS.4.1.1 Signalling ProcedureBSC determines what channel shall be used and starts up that channel at BTS by sendin

48、g a CHANnelACTIVation message to the relevant TRX. This message contains the reason for the activation(immediate assignment, assignment, asynchronous/synchronous handover, additional assignment,activation of a secondary channel in a multislot configuration), the identification of the channel to be u

49、sed(channel no) and a complete description of the channel (full/half rate, speech/data, coding/rate adaption,hopping sequence, encryption key etc.).If the Encryption Information field is present, the activation is done with ciphering active. If the EncryptionInformation element is not present, activation is done without ciphering.After activating the channel as requested, TRX responds with the CHANnel ACTIVation ACKnowledgemessage. This message contains the current frame number at BTS. The frame number is used by BSC todetermine the
