The one for the initial registration is as follows. The message is sent via the bssap sccp connection established for the associated dedicated resource. Cm service reject if the msc is changed 3a.

Open the cm configuration file (brm_home /sys/cm/pin.conf) and look for the following entries:

Supplementary service activation call generation and reception. Maps™ gsm a acts as base station controller (bsc) and initiates the mobile originating call procedure by sending cm service request to the dut (msc). Simply put, this message is to tell the network i want to camp on you, please allocate me a radio resource that i initiate the connection process. 0.10 0100 = dtap mobility management message type:

Base station system management application part. (cause=’mac failure’ or ‘gsm authentication unacceptable’) sent authentication & ciphering request received on first expiry, the ms should consider the network as false (0) lcs value added location request notification capability not supported ucs2 : A service request is a procedure an ue executes when it is in idle mode and needs to establish the bearers to send data or it needs to send signaling to the mme.

Here first a channel request has to be sent to the bts and then it is tried with the cm_res_req to reestablish an rr connection for the still existing and active mm and cc connection. The mobile initiates a lapm connection with the bsc by sending a set asynchronous balanced mode (sabm) message. This message is sent by the network when a paging request with cs call indicator was received via sgs for a ue, and a nas signalling connection is already established for the ue.

Cause value = 25 “llc or sndcp failure (gsm only)” (gprs specific cause values for session management) this cause code is used by the ms indicate that a pdp context is deactivated because of a llc or sndcp failure (e.g. The authentication and encryption flow is started on the caller side. The ms sends a cm service request, the ms initiates multiframe mode in sap3 with the normal lapdm sabm procedure. In this process, the msc may need to obtain the authentication set from the hlr/authentication.

The dut on receipt of a cm service request message should send a cc connection confirm message in response as shown in the figure below. The ue triggered service request procedure is outlined in figure 17.8. Cm service request location area update or combined ra/la update 5. The service request message meant for the msc is also sent in this message.
The a interface supports several applications parts:
