Ageing population is increasing compared to general population. Related to this, a group of social-healthcare services, known as Ambient Assisted Living (AAL) services, are appearing to promote health and wellness in elderly people. IP Multimedia Subsystem (IMS) technology can help to face this challenge providing networks convergence and a fast and solid service implementation. IMS offers a group of common services which can be reused in different applications, and enable the running of the same application over any device, anywhere and anytime. We propose a conceptual implementation of AAL services through generic IMS services (service enablers), We also show the benefits they can offer in order to support a healthy and independent life on elderly people.
