TR 23.869 (SA2)
Support for
IP-based IMS Emergency calls over GPRS and EPS

|   ToC   |   3GPP‑Page   |   Help   |

(W-zip) V9.0.0    2009/03    36 p.


Rapporteur:  Ms. Barclay, Deborah

This TR has been created for the purpose of having a single source for documenting the GPRS and EPS enhancements to support emergency calls. As solutions to particular aspects are agreed, CRs will be created for the associated TSs.

This TR is not a study. The IMS Emergency Services study is available in TR 23.867. This TR includes the following:
  • Functionality needed to meet the requirements as defined in TS 22.101 and TS 23.167 for handling IMS emergency calls over the GPRS using GERAN and UTRAN access both in the case where the UE is in normal service mode (e.g., UE has sufficient credentials and is authorized to receive the service) and where the UE is in limited service mode (e.g. the UE does not have sufficient credentials or is not authorized to receive GPRS service).
  • Functionality needed to meet the requirements as defined in TS 22.101 and TS 23.167 for handling IMS emergency calls over the EPS using E-UTRAN access both in the case where the UE is in normal service mode (e.g., UE has sufficient credentials and is authorized to receive the service) and where the UE is in limited service mode (e.g. the UE does not have sufficient credentials or is not authorized to receive EPS service).
  • EPS functionality needed to support IMS emergency call handovers between 3GPP accesses and between 3GPP and non-3GPP accesses.
    Note:  Access network specific impacts for a UE to attach to the non-3GPP access network for emergency calling are out of scope of 3GPP.
  • EPS functionality to support of IMS emergency calls that complies with applicable requirements for provision of location information as defined in TS 23.167.
