Example text

The SCP is located in the service layer. The service layer may contain a multitude of nodes, but for IN the SCP is the main entity through which control over the call may be asserted. 1 History of Intelligent Networks Development of IN in the form that it is currently known started in the mid-1980s. One of the first IN standards was Bellcore’s1 advanced IN (AIN). AIN was developed as an IN standard for landline digital networks. A later IN standard was the wireless IN (WIN), which targets the mobile networks, amongst which is the personal communication system (PCS).

The SSF will in that case not wait for instructions from the SCP, but will return the call control immediately to the MSC. As a result the call processing is not halted. The SCP has not gained control over the call; the SCP was merely notified about the occurrence of the call event. The use of TDP-N is not very common for IN. CAMEL defines TDP-R, but not TDP-N. • Event detection point – request (EDP-R): When an IN service is invoked, it may arm DPs within the BCSM as an event detection point (EDP).

This helps designers and implementers identify the specific document that is needed for the CAMEL specification in a specific GSM or 3G release. 4 lists the document version number per GSM or 3GPP release. z) is increased. z part of the version number is normally stepped. 078) specifies the syntax of CAP. There is often confusion about the priority of these specifications where it comes to optionality of information elements that may be carried in CAMEL operations. The rule is as follows: • stage 2 defines semantics for the information flows (IF) and information elements (IE) that may be sent between gsmSSF and gsmSCF; • stage 3 defines the syntax of conveying these IEs, encoded as operation parameters, through the CAP protocol.
