  • the CAMEL feature has been provided in the GSM system in order to allow network operators to provide access to the subscriber services including operator specific services, even when the user is roaming (i.e. being served by a different network than the network to which his mobile terminal is subscribed: a visited public land mobile network (VPLMN)).
  • VPN visited public land mobile network
  • CAMEL has been developed over the years since its introduction, and the CAMEL standardisation has presently reached CAMEL phase 4. Earlier releases of the CAMEL standard, have gradually made available development of a number of mobile telecommunication services.
  • CAMEL phase 1 supports some basic enhanced functionality, on top of regular voice and data calls. An example of this is a basic version of the virtual private network (VPN) service.
  • VPN virtual private network
  • CAMEL phase 4 a large number of telecommunication services is supported for roaming users, such as conference calls, enhanced VPN services and network-initiated call establishment.

  • a disadvantage of the use of the N-CSI trigger in CAMEL phase 3 and CAMEL phase 4 is that it only supports the provisioning of services supported under CAMEL phase 3 or 4. This implies that the MSCs and the service nodes in the VPLMN need to support CAMEL phase 3 or 4. Moreover, mobile networks that do not support CAMEL phase 3 or phase 4 features do not support use of an N-CSI trigger, and therefore lack the possibility of providing specific services available in the VPLMN to inbound roaming users. Even if CAMEL phase 3 is supported by the VPLMN, but not CAMEL phase 4, then the use of the N-CSI trigger is limited, and therefore the service provider in the VPLMN will not be able to provide additional services to the inbound roaming users at all times.

If no home service subscription information is provided by the HLR, then the user does not have CAMEL services for outbound roaming that are available to him in the VPLMN, and that are provided by the HPLMN. In that case, by generating replacement subscription information, the VLR is made into "thinking" that an O-CSI or VT-CSI has been provided by the HLR.
