So is there a difference when we speak of applications and services? From an end- user perspective, applications and services can be defined as follows :
Applications and services can be classified into four main categories, namely:
Services can also be classified into push and pull services. Push services are those that are delivered to the user without the user actively requesting them. Weather or flight updates, stock quotes, and news could be types of content that can be delivered via push services. Advertisements can also be classified as push services. The network has to be designed to support push services. User profiles would specify the type of services that the user has subscribed to or is capable of accessing. Pull services are typically the ones where the user initiates a request and obtains the content or sets up a session as a result. Web browsing is a typical pull service where the user requests information from some URL. The types of services and applications that are offered and used by subscribers depend on whether the mobile service is used for business reasons or for personal use. Corporate and enterprise users are generally heavy users of mobile services and hence are normally targeted by the operators when launching new services. |
