All refrences to claim(s) which appear below refer to the numbering after this setence.
1. Call management procedures for use in a Long Term EvolutionSystem Architecture Evolution (LTESAE) system, said system including a Serving GPRS Support Node (SGSN) and an Evolved Universal Terrestrial Radio Access Network (EUTRAN), said procedures comprising:
a Mobility Management Entity (MME) arranged to provide Non-Access Stratum (NAS) signaling between the SGSN and the EUTRAN according to General Packet Radio Service (GPRS) Mobility Management (MM) procedures;
wherein the MME is arranged to provide NAS signaling according to GPRS Session Management (SM) procedures;
wherein the SM for LTESAE includes a packet data protocol (PDP) context in order to establish, modify or tear down PDP sessions; and,
wherein the procedures establish, modify or tear down PDP sessions in the same manner as that in GMMSM, as performed from the MME or a User Equipment (UE).
2. The call management procedures of claim 1, further comprising an authentication and ciphering procedure for LTESAE whereby authentication and key agreement between the UE and MME can take place.
3. The call management procedures of claim 2, wherein the ciphering and integrity protection of the MM and SM information for LTESAE is provided by the conventional procedure or by a new specific security mode command for the MME for LTESAE in a similar way as the one used by lower layers in UTRAN.
4. A telecommunications system, comprising: an Serving GPRS Support Node (SGSN);
