The objective is to study use cases and propose potential requirements to enhance the information set (e.g., user's subscription, application characteristics) upon which paging policies may be based to allow optimization of the paging procedures in LTE.
The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
References are either specific (identified by date of publication, edition number, version number, etc.) or non specific.
For a specific reference, subsequent revisions do not apply.
For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.

The 3GPP core network can take various information into account to determine the paging policies. The network should be able to identify UEs requiring priority treatment. During congestion, the network should be able to provide priority treatment to those UEs that require it.
It does not have additional requirements on the 3GPP system.
The 3GPP network shall be able to take the movement of a device into account when paging the device.
The 3GPP core network shall be able to identify the traffic's application characteristics (e.g. application type, application protocol, application provider, and delay sensitivity).
The 3GPP core network shall be able to apply different paging policies based on application characteristics provided by a source known to and trusted by the serving network (e.g. the home network).
The 3GPP core network may be able to take the likely location of the UE within the paging area into account when paging the UE.
The study has identified several use cases where the 3GPP system could optimize the paging procedures in LTE. It has also resulted in a set of potential requirements as captured in the previous section.
It is recommended that the requirements in this TR are taken as a basis for the development of normative requirements.
