Abstract: A method and system for re-establishing a disconnected emergency call to an emergency call network for emergency call continuation in case of Public Safety Answering Point (PSAP) failure(s) can be utilized without the need of any manual steps taken by the caller and/or the call taker. Embodiments can be configured to detect a failure in the PSAP operating the emergency call by a Next Generation Core Services (NGCS), which thereupon will not release the emergency call to the failed PSAP but will send it to a dynamically identified fallback PSAP.

Abstract: Methods and apparatuses for coordinating session recordings in an IP environment can be configured so that a session is to be recorded by session recording clients, SRCs, which are located along the signaling path of the session. An SRC can attach a first SRC parameter indicating that it is available for recording the communication session upon receiving a first downstream message. The first SRC parameter can be incremented by e available SRCs downstream the signal path. One of the SRCs, can further attach a second SRC parameter indicating that this SRC records the communication session upon receiving a first upstream message as an answer to the first downstream message. In the first upstream message, the first SRC parameter can be decremented by each of the available SRCs upstream the signal path and the second SRC parameter can be propagated to each of the available SRCs upstream the signal path.
