The interfac
45、e between the CLF and the AF is known as the e2 interface (figure 1). A Connectivity session Location and repository Function (CLF) is a data base in an access network that maintains information associated to an IP address and/or an access identifier in the form of dynamic session records or static
46、access records, respectively. How a CLF obtains this information is outside the scope of the present document. ETSI ETSI ES 283 035 V3.1.1 (2015-04) 9 In the context of the present document, an Application Function (AF) represents any network element offering - or providing access to - applications
47、that require information about the characteristics of the IP-connectivity session used to access such applications. Annex A provides background information on the use of a CLF in NGN architectures (ETSI ES 282 001 i.1). g4g38g18g62g38g104g28 g4g272g272g286g400g400g3g69g286g410g449g381g396g364g3g90g2
