'''Customized Applications for Mobile networks Enhanced Logic''' ('''CAMEL''') is a set of standards designed to work on either a [[Network Switching Subsystem|GSM core network]] or the [[Universal Mobile Telecommunications System]] (UMTS) network(4g+LTE.+cGHsa+. The framework provides tools for operators to define additional features for standard [[GSM services]]/UMTS services. The CAMEL architecture is based on the [[Intelligent Network]] (IN) standards, and uses the [[CAMEL Application Part|CAP]] protocol. The protocols are codified in a series of [[ETSI]] Technical Specifications.

Many services can be created using CAMEL, and it is particularly effective in allowing these services to be offered when a subscriber is [[roaming]], like, for instance, noNo-prefix dialing (the number the user dials is the same no matter the country where the call is placed) or seamless [[Multimedia Messaging Service|MMS]] message access from abroad.

CAMEL specification were published in phases,<ref name="Release 96 Spec">[http://www.3gpp.org/ftp/Specs/archive/02_series/02.78/0278-560.zip 3GPP TS 02.78] Release 96 specification for the service aspects of CAMEL Phase 1 & 2 (zip file).</ref> with four phases having been established {{as of|2007}}, each building on the previous.<ref name="Release 5 Spec">[http://www.3gpp.org/ftp/Specs/archive/22_series/22.078/22078-5f0.zip 3GPP TS 22.078] Release 5 specification for CAMEL phase 4 (zip file).</ref> Phases 1 and 2 were defined before [[3G]] networks existed, and as such support adding IN services to a [[Global System for Mobile Communications|GSM]] network, although they are equally applicable to 2.5G and 3G networks. Phase 3 was defined for [[3GPP]] Releases 99 and 4, and hence is a GSM and [[Universal Mobile Telecommunications System|UMTS]] common specification, while Phase 4 was defined as part of 3GPP Release 5.
