Abstract

A method and device for receiving a broadcast/multicast service as discussed. According to an embodiment, the invention provides a method of receiving a broadcast/multicast service by a terminal, the method comprising: receiving a service guide from a network including a broadcast/multicast server, the service guide being used by a user to select specific contents related to a broadcast/multicast service; transmitting information on the contents selected by the user, to the network; transmitting a content request to the network; and receiving contents from the network in response to the content request, wherein the received contents were further selected, among the contents selected by the user, by the broadcast/multicast server that performed an exact location tracking of the terminal to enable location based filtering of services corresponding to the contents selected by the user.

Claims

1. A method of receiving a broadcast/multicast service by a terminal, the method comprising:

receiving a service guide from a network including a broadcast/multicast server, the service guide being used by a user to select specific contents related to a broadcast/multicast service;

transmitting information on the contents selected by the user, to the network;

transmitting a content request to the network; and

receiving contents from the network in response to the content request, wherein the received contents were further selected, among the contents selected by the user, by the broadcast/multicast server that performed an exact location tracking of the terminal to enable location based filtering of services corresponding to the contents selected by the user.

2. The method of claim 1, wherein the received contents were filtered by the broadcast/multicast server according to an exact current location of the terminal, upon cooperating with a network entity to process location information regarding the terminal.

3. The method of claim 1, wherein the received contents were filtered by the broadcast/multicast server according to an exact current location of the terminal, upon performing the exact location tracking of the terminal with a network entity connected with a contents provider.

4. The method of claim 1, wherein the exact location tracking performed at the network involves an exchange of messages based on a mobile location protocol (MLP) format.

5. The method of claim 1, wherein the received service guide contains information related to at least one among a group of information comprising:

broadcast areas, target areas, horizontal accuracy, geographic area shapes, country codes, geopolitical area names, postal zip codes, service areas, services lists, terminal identifications, user settings, proprietary elements, and application-specific elements.

6. A terminal for receiving a broadcast/multicast service, the terminal comprising:

a transceiver configured to receive and transmit signals through a network; and

a client module configured to cooperate with the transceiver and to;

receive a service guide from the network including a broadcast/multicast server, the service guide being used by a user to select specific contents related to a broadcast/multicast service;

transmit information on the contents selected by the user, to the network;

transmit a content request to the network; and

receive contents from the network in response to the content request, wherein the received contents were further selected, among the contents selected by the user, by the broadcast/multicast server that performed an exact location tracking of the terminal to enable location based filtering of services corresponding to the contents selected by the user.

7. The terminal of claim 6, wherein the received contents were filtered by the broadcast/multicast server according to an exact current location of the terminal, upon cooperating with a network entity to process location information regarding the terminal.

8. The terminal of claim 6, wherein the received contents were filtered by the broadcast/multicast server according to an exact current location of the terminal, upon performing the exact location tracking of the terminal with a network entity connected with a contents provider.

9. The terminal of claim 6, wherein the exact location tracking performed at the network involves an exchange of messages based on a mobile location protocol (MLP) format.

10. The terminal of claim 6, wherein the received service guide contains information related to at least one among a group of information comprising:

broadcast areas, target areas, horizontal accuracy, geographic area shapes, country codes, geopolitical area names, postal zip codes, service areas, services lists, terminal identifications, user settings, proprietary elements, and application-specific elements.
