Method and a mobile terminal for performing a handover in a broadcast system
First Claim
1. A method of operating a mobile terminal, the method comprising:
- receiving data relating to available broadcast programs in a first network area, and storing said data in the mobile terminal;
whilst receiving a first program from a transmitter in the first network area, detecting a need for handover to a second network area;
using data relating to available broadcast programs in the second network area to determine if the first program is available in the second network area, and receiving the first program from a transmitter in the second network area if it is available, and otherwise determining at least one program which is similar to the first program, and subsequently receiving the at least one similar program from the second network area transmitter.

Abstract
In a digital broadcasting network, a mobile terminal receives hierarchical ESG data relating to available broadcast programs adjacent network areas. The terminal is operable whilst receiving a first program from a transmitter in a first network area for detecting a need for handover to a second network area, and for then determining from the ESG data if the same program is available in the second network area If it is, the terminal then receives the program from a transmitter in the second network area. Otherwise, it determines one or more programs which are similar to the first program, and presents them on a display for selection by a user. This involves determining which programs have an identifier in common with the first program. The identifier can be any one or more of a program identifier, a service identifier, a channel identifier, a category identifier and a genre identifier, for example.

15. A mobile terminal, comprising:
-
a receiver arranged to receive data relating to available broadcast programs in first and second network areas;
a memory arranged to store said program data;
a handover handler operable whilst the terminal is receiving a first program from a transmitter in the first network area for detecting a need for handover to a second network area;
a program data processor arranged to use the data relating to available broadcast programs in the first and second network areas to determine if the same program is available in the second network area, and otherwise to determine at least one program which is similar to the first program; and
a controller arranged to control the mobile terminal to receive from the second network area transmitter one of;
a) the first program, and b) the at least one similar programs, as appropriate. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)
