Abstract
The invention provides a method and system for handling a session setup procedure initiated by an user equipment for establishing a session of a specific type to a called entity, wherein a session setup request sent to a network entity for establishing the requested session, includes location information and an identifier for identifying the called entity. A database is provided which stores a list of location information and associated identifiers. The network entity accesses this database, wherein, when detecting that the identifier represents a session of the specific type in an area represented by the location information, the session set-up is continued in a manner appropriate for a session of the specific type.
Claims30
A method, comprising:
- processing a session setup procedure initiated by a user equipment for establishing a session of a specific type to a called entity;
- receiving a session setup request to a network entity for establishing the session, wherein the session setup request includes location information and an identifier for identifying the called entity;
- accessing by the network entity a database which comprises location information and associated identifiers;
- determining an occurrence of a session setup in an internet protocol multimedia subsystem/packet switched network;
- when detecting that the identifier represents an emergency session in an area represented by the location information, continuing the session set-up by sending a message to the user equipment to inform the user equipment that the identifier is an identifier for initiating the emergency session;
- and
- in response to sending the message to inform the user equipment that the identifier is an identifier for initiating the emergency session, terminating the session setup in the internet protocol multimedia subsystem/packet switched network by the network entity without completing the emergency session setup in the internet protocol multimedia subsystem/packet switched network.

An apparatus, comprising:
- a processor configured to
- receive a session setup request initiated by a user equipment for establishing a session of a specific type to a called entity, wherein the session setup request includes location information and an identifier for identifying the called entity,
- access a database comprising location information and associated identifiers representing requests for sessions of a specific type,
- determine an occurrence of a session setup in an internet protocol multimedia subsystem/packet switched network,
- when detecting that the identifier represents an emergency session in an area represented by the location information, continue the session set-up by sending a message to the user equipment to inform the user equipment that the identifier is an identifier for initiating the emergency session, and
- in response to sending the message to inform the user equipment that the identifier is an identifier for initiating the emergency session, terminate the session setup in the internet protocol multimedia subsystem/packet switched network without completing the emergency session setup in the internet protocol multimedia subsystem/packet switched network.

- and
- a processor configured to
- receive a session setup request for establishing the session, wherein the session setup request includes location information and an identifier for identifying a called entity,
- access the database comprising the location information and the associated identifiers,
- determine an occurrence of a session setup in an internet protocol multimedia subsystem/packet switched network,
- when detecting that the identifier represents an emergency session in an area represented by the location information, continue the session set-up by sending a message to the user equipment to inform the user equipment that the identifier is an identifier for initiating the emergency session, and
- in response to sending the message to inform the user equipment that the identifier is an identifier for initiating the emergency session, terminate the session setup in the internet protocol multimedia subsystem/packet switched network without completing the emergency session setup in the internet protocol multimedia subsystem/packet switched network.
