Abstract
The present invention relates to arrangements and methods for distribution of warning information relating to an emergency to mobile users. Warning information is sent to UEs both within and outside an area affected, or an area estimated to be affected by the emergency. The warning information comprises information associated with the affected area, or the area which is estimated to be affected, e.g. geographical information or identities of the base stations within said area.

41. A method in a network node for transmitting warning information associated with an emergency to user equipments (UEs) camped on or connected to the network node, the method comprising:
-
receiving information associated with the emergency from a system that collected that information; processing the received information to retrieve information associated with an area affected by, or estimated to be affected by, the emergency; and transmitting the retrieved information to the UEs camped on or connected to the network node independently of whether those UEs are located in said area. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51)

52. A method in a User Equipment (UE) for receiving warning information associated with an emergency from a warning system connectable to a mobile communication network with which the UE is configured to communicate, the method comprising:
-
receiving from a network node information associated with an area affected by, or estimated to be affected by, the emergency independently of whether the UE is located in said area; processing the received information to combine the received information with map information representing at least a part of said area; and presenting the combined information to a user of the UE via a user interface. - View Dependent Claims (53, 54, 55, 56, 57, 58, 59, 60, 61)

62. A network node configured to transmit warning information associated with an emergency to User Equipments (UEs) camped on or connected to the network node, the network node comprising:
-
a receiver for receiving information associated with the emergency from a system that collected that information, a processor configured to process the received information to retrieve information associated with an area affected by, or estimated to be affected by, the emergency, and a transmitter for transmitting the retrieved information to the UEs camped on or connected to the network node independently of whether those UEs are located in said area. - View Dependent Claims (63, 64, 65, 66, 67, 68)

69. A User Equipment (UE) configured to receive warning information associated with an emergency from a warning system connectable to a mobile communication network with which the UE is configured to communicate, the UE comprising:
-
a receiver for receiving from a network node information associated with an area affected by, or estimated to be affected by, the emergency independently of whether the UE is located with said area; a processor configured to process the received information to combine the received information with map information representing at least a part of said area; and a user interface configured to present the combined information to a user. - View Dependent Claims (70, 71, 72, 73, 74, 75, 76, 77)
