Method and apparatus for reliable broadcast/multicast service
First Claim
1. An apparatus comprising:
- a memory; and
a processor operatively coupled to the memory and comprising one or more processing circuits configured to store information relating to user service registrations performed using an IP-based connection established to enable connectivity between a user terminal and a service node for an IP-based broadcast/multicast service;
wherein the stored information enables re-registration of at least some of any of the user services affected by a loss of the IP-based connection;
wherein the one or more processing circuits of the processor are further configured to, in response to noticing the loss of the IP-based connection;
establish a new IP-based connection, or select another active IP-based connection, as a replacement IP-based connection to replace the lost IP-based connection; and
use the stored information to re-register at least some of the user services affected by the loss of the IP-based connection, the re-registration being performed using the replacement IP-based connection.

Abstract
A method is provided for use by a user terminal operating an IP-based multimedia broadcast/multicast service. The method comprises storing information relating to user service registrations performed using an IP connection such as a Packet Data Protocol, PDP, context established to enable connectivity between the user terminal and a service node for the broadcast/multicast service. The information is of a type to enable re-registration of at least some of any of the user services affected by a loss of the IP connection. In one embodiment, the multimedia broadcast/multicast service is a 3GPP Multimedia Broadcast/Multicast Service, MBMS, the user terminal is a User Equipment, UE, and the service node is a Broadcast/Multicast Service Center, BM-SC. In another embodiment, the multimedia broadcast/multicast service is an Open Mobile Alliance Broadcast, OMA BCAST, service, the user terminal is a Terminal, and the service node is an OMA BCAST Subscription Management, BSM, node.

14. A method implemented by an apparatus comprising a user terminal or an element in a user terminal, the method comprising:
-
storing information relating to user service registrations performed using an IP-based connection established to enable connectivity between the user terminal and a service node for an IP-based broadcast/multicast service; wherein the stored information enables re-registration of at least some of any of the user services affected by a loss of the IP connection; the method further comprising, in response to noticing the loss of the IP-based connection; establishing a new IP-based connection, or selecting another active IP-based connection, as a replacement IP-based connection to replace the lost IP-based connection; and using the stored information to re-register at least some of any of the user services affected by the loss of the IP-based connection, the re-registration being performed using the replacement IP-based connection. - View Dependent Claims (15, 16, 17)

18. A computer program product stored in a non-transitory computer readable storage medium for controlling an apparatus comprising a user terminal or an element in a user terminal, the computer program product comprising software instructions which, when run on the apparatus, causes the apparatus to:
-
store information relating to user service registrations performed using an IP-based connection established to enable connectivity between the user terminal and a service node for an IP-based broadcast/multicast service; wherein the stored information enables re-registration of at least some of any of the user services affected by a loss of the IP connection; in response to noticing the loss of the IP-based connection; establish a new IP-based connection, or select another active IP-based connection, as a replacement IP-based connection to replace the lost IP-based connection; and use the stored information to re-register at least some of the user services affected by the loss of the IP-based connection, the re-registration being performed using the replacement IP-based connection.
