Emergency session request handling in a network
First Claim
1. A method for processing a session setup procedure initiated by an user equipment in a network comprising at least one supporting entity, the user equipment is allowed to initiate sessions of a first type or types and the user equipment is not allowed to initiate sessions of a second type or types, wherein the user equipment initiates a session and one of the supporting entities or another control entity checks whether or not the initiated session is actually a session of the first type, and the initiated session is terminated, if detecting that it is at least partially a session of the second type.

Abstract
The invention provides a method and system for handling a session request of a user equipment in a network comprising at least one supporting entity, in particular in a case where the user equipment is not allowed to initiate other session apart from specific session type. At least one of the supporting entities or another control entity is adapted to check whether or not the initiated session is actually continued as a session of the specific type. The session is forcibly terminated when detecting that it is not continued as such a session. A timer may be started when the user equipment attaches to the network for requesting a session, and the user equipment is detached from the network when not continuing with a session of the specific type within a defined time after attach.

- 1. A method for processing a session setup procedure initiated by an user equipment in a network comprising at least one supporting entity, the user equipment is allowed to initiate sessions of a first type or types and the user equipment is not allowed to initiate sessions of a second type or types, wherein the user equipment initiates a session and one of the supporting entities or another control entity checks whether or not the initiated session is actually a session of the first type, and the initiated session is terminated, if detecting that it is at least partially a session of the second type.
- 3. A method for detaching an user equipment from a network, wherein the user equipment is allowed to initiate sessions of a first type or types and the user equipment is not allowed to initiate sessions of a second type or types, wherein a time check is started when the user equipment attaches to the network for requesting a session of the first type or types, and the user equipment is detached from the network when there is no bearer active for the session within a defined time after the attach.
- 15. A system for processing a session setup procedure initiated by an user equipment in a network comprising at least one supporting entity, the user equipment being adapted to be allowed to initiate sessions of a first type or types and the user equipment not to be allowed to initiate sessions of a second type or types, wherein, when the user equipment initiates a session, one of the supporting entities or another control entity being adapted to check whether or not the initiated session is actually a session of the first type, the initiated session being terminated, if detecting that it is at least partially a session of the second type.
- 17. A system for detaching an user equipment from a network, wherein the user equipment is allowed to initiate sessions of a first type or types and the user equipment is not allowed to initiate sessions of a second type or types, comprising a time check means adapted to start a time check for a defined time when the user equipment attaches to the network for requesting a session of the first type or types, the system being adapted to detach the user equipment from the network when there is no bearer active for the session within the defined time after the attach.
- 29. A network element preferably to be used in a system or method for processing a session setup procedure initiated by an user equipment, the user equipment being adapted to be allowed to initiate sessions of a first type or types and the user equipment not to be allowed to initiate sessions of a second type or types, wherein the network element is adapted to terminate an initiated session when it is detected that the session is at least partially a session of the second type.
