ETSI TR 122 953 presents the results of the feasibility study on Multimedia Priority Service. The intent of this feasibility study is to assess the ability of 3GPP specifications to meet high-level requirements identified for Multimedia Priority Service. This feasibility study consisted of a multi-step process, namely:

• Identify high-level requirements for Multimedia Priority Service.
• Determine relevant 3GPP specifications for Multimedia Priority Service.
• Perform a Gap Analysis to assess the ability of existing 3GPP specifications to meet the high-level Multimedia Priority Service requirements.

Additional functionalities not documented in this TR are considered outside the scope of this TR. Such additional functionality may be on a network-wide basis, nation-wide basis or particular to a group of users.

The Multimedia Priority Service is intended to be utilised for both Voice and Data in the Packet-switched (PS) domain and the IP Multimedia Subsystem (IMS).

The Multimedia Priority Service is intended to interwork with external networks to provide an end-to-end service. Therefore, service interactions with external networks are considered within the scope of this document, although the specification of these interactions may be in other standards. If this occurs, a reference to that specification is made.
