1. An apparatus comprising:
at least one processor; and
at least one memory including computer program code,
the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to
perform a specific extensible authentication protocol-based procedure without mutual authentication between said apparatus and a packet core network, upon establishment of a connection between said apparatus and a trusted wireless local area network access network for access by said apparatus to emergency services over said trusted wireless local area network access network to said packet core network,
within said procedure, receive a message comprising an indication that said access is for limited service, and an indication of connection modes for said access over said trusted wireless local area network access network, the connection modes including at least one of a single-connection mode or a multiple-connection mode,
within said procedure, negotiate with said packet core network a connection mode of said connection modes for said access over said trusted wireless local area network access network, and
within said procedure, derive a master session key for said access, without use of a ciphering key and an integrity key, but using an identity provided by the apparatus,
wherein said connection mode comprises one of the single-connection mode and the multiple-connection mode, and
wherein said trusted local area network access network is configured to interface to said packet core network via an interface to a packet data network gateway.
