Subscriber-driven sharing of a communications service

Abstract

A system and method for facilitating service sharing (e.g., voice services, data services, multimedia services, etc.) in a network environment (). In one example arrangement, upon receiving an input at a host subscriber device (), a request is generated () to a host subscriber's service provider network () for instantiating a virtual subscriber identification module (vSIM) populated with the host subscriber's service profile with respect to a service. A guest user's authentication information is provided () for performing guest registration and remote provisioning () for the vSIM, the remote provisioning including allocation of a temporary phone number and an IP address, which may be used in a mapping relationship for routing calls or sessions engaged by the guest () using a service shared with the host subscriber ().
