Methods, apparatus, and system for edge resolution function

Abstract

Methods, apparatus, systems, architectures and interfaces for a wireless transmit receive unit (WTRU) performing a client-side edge resolution function (cERF) are provided. A method may include any of: transmitting, to a network-side edge application resolver (nEAR), a signal requesting an IP address identifying (e.g., associated with) a domain name system (DNS) server associated with the WTRU; applying, by the WTRU, any of edge instance (EI) record rules for the identified DNS server, or updating EI records with the IP address identifying the DNS server; transmitting, to a DNS server, a DNS query associated with a fully qualified domain name (FQDN); receiving, in response to the DNS query, FQDN resolution from the DNS server; on condition that a mobility event of the WTRU occurs, transmitting, to the nEAR, a signal requesting information for updating the EI records of the WTRU; and applying, by the WTRU, any of the updated EI record rules in order to perform any of: (1) redirecting application session traffic to provides session continuity for the WTRU, and (2) breaking any number of application sessions.

What is claimed is: 
     
         1 . A method for a wireless transmit receive unit (WTRU) performing a client-side edge resolution function (cERF), the method comprising:
 transmitting, to a network-side edge application resolver (nEAR), a signal requesting an IP address identifying (e.g., associated with) a domain name system (DNS) server associated with the WTRU;   applying, by the WTRU, any of edge instance (EI) record rules for the identified DNS server, or updating EI records with the IP address identifying the DNS server;   transmitting, to a DNS server, a DNS query associated with a fully qualified domain name (FQDN);   receiving, in response to the DNS query, FQDN resolution from the DNS server;   on condition that a mobility event of the WTRU occurs, transmitting, to the nEAR, a signal requesting information for updating the EI records of the WTRU; and   applying, by the WTRU, any of the updated EI record rules in order to perform any of: (1) redirecting application session traffic to provides session continuity for the WTRU, and (2) breaking any number of application sessions.   
     
     
         2 . The method of  claim 1 , further comprising detecting, by the WTRU, the mobility event of the WTRU; and
 updating any of EI records and traffic steering rules.   
     
     
         3 . The method of  claim 1 , wherein the transmitting the DNS query to the DNS server comprises transmitting a request for edge information to the network-side edge application resolver (nEAR). 
     
     
         4 . The method of  claim 1 , wherein edge instance information included in the EI records includes information associated with any of an EI IP address, an EI FQDN, EI clients, and EI options. 
     
     
         5 . (canceled)
