Method and apparatus for service continuity on a mobile communication device
View Patent ↗A method and apparatus for service continuity on a mobile communication device is disclosed. The method can include receiving ( 320 ) a first service on a first carrier, where the first service can have a multicast subframe allocation pattern. The method can include establishing ( 340 ) a connection on a second carrier on a universal mobile telecommunication system. The method can include informing ( 350 ) a source of the second carrier of the multicast subframe allocation pattern of the first service. The method can include receiving ( 360 ) scheduling grants for subframes on the second carrier. The subframes corresponding to the received scheduling grants can be distinct from subframes corresponding to the multicast subframe allocation pattern of the first service. The method can include receiving ( 370 ) a second service on the second carrier based on the scheduling grants while receiving the first service on the first carrier.
1. A method in a wireless terminal comprising:
receiving a first service on a first carrier, the first service having a multicast subframe allocation pattern;

receiving a second service on the second carrier based on the scheduling grants while receiving the first service on the first carrier,
wherein the multicast subframe allocation pattern includes a transmission gap pattern with respect to the first service, the transmission gap pattern indicating gaps in a transmission pattern with the first carrier during which the wireless terminal cannot be scheduled a service on the second carrier.
2. The method according to claim 1 , wherein the first service comprises a multicast service and the second service comprises a unicast service.
3. The method according to claim 1 , wherein the multicast subframe allocation pattern comprises a pattern of subframes assigned to the first service.
4. The method according to claim 1 , further comprising monitoring paging on the first carrier for service on a different carrier while receiving the first service on the first carrier.
5. The method according to claim 1 , further comprising monitoring paging on the second carrier while receiving the first service on the first carrier.
6. The method according to claim 1 , wherein the universal mobile telecommunication system comprises an evolved universal mobile telecommunication system terrestrial radio access system.
7. The method according to claim 1 , wherein informing a source of the second carrier of the multicast subframe allocation pattern comprises informing, in a radio resource control connection establishment complete message, a source of the second carrier of the multicast subframe allocation pattern of the first service.
8. The method according to claim 1 , wherein establishing the connection on the second carrier comprises establishing the connection on the second carrier on a universal mobile telecommunication system before receiving the first service on the first carrier.
9. The method according to claim 1 , wherein informing the source of the second carrier further comprises informing the source of the second carrier of a service identity of the first carrier.
10. An apparatus comprising:
a wireless communication device housing;
a transceiver coupled to the wireless communication device housing, the transceiver configured to receive a first service on a first carrier, the first service having a multicast subframe allocation pattern; and
a controller coupled to the transceiver, the controller configured to control operations of the apparatus and configured to establish, via the transceiver, a connection on a second carrier on a universal mobile telecommunication system while receiving the first service, and configured to inform, via the transceiver, a source of the second carrier, of the multicast subframe allocation pattern of the first service,
wherein the transceiver is configured to receive scheduling grants for subframes with respect to the second carrier, the subframes corresponding to the received scheduling grants being distinct from subframes corresponding to the multicast subframe allocation pattern of the first service,
wherein the transceiver is configured to receive a second service on the second carrier based on the scheduling grants while receiving the first service on the first carrier, and
wherein the multicast subframe allocation pattern includes a transmission gap pattern with respect to the first service, the transmission gap pattern indicating gaps in a transmission pattern with the first carrier during which the apparatus cannot be scheduled a service on the second carrier.
11. The apparatus according to claim 10 , wherein the first service comprises a multicast service and the second service comprises a unicast service.
12. The apparatus according to claim 10 , wherein the multicast subframe allocation pattern comprises a pattern of subframes assigned to the first service.
13. The apparatus according to claim 10 , wherein the transceiver is configured to monitor paging on the second carrier while receiving the first service on the first carrier.
14. The apparatus according to claim 10 , wherein the transceiver is configured to monitor paging on the first carrier for a service on a different carrier while receiving the first service on the first carrier.
15. The apparatus according to claim 10 , wherein the service continuity module is configured to inform, via the transceiver, in a radio resource control connection establishment complete message, a source of the second carrier of the multicast subframe allocation pattern of the first service.
16. The apparatus according to claim 10 , wherein the controller is configured to establish a connection on the second carrier by establishing, via the transceiver, a connection on the second carrier on the universal mobile telecommunication system before receiving the first service on the first carrier.
17. The apparatus according to claim 10 , wherein the service continuity module is configured to inform a source of the second carrier of the multicast subframe allocation pattern by informing, via the transceiver, a source of the second carrier of a service identity of the first carrier.
18. A method comprising:
receiving a multicast service on a first carrier, the multicast service having a multicast subframe allocation pattern including a pattern of subframes assigned to the multicast service;
establishing a connection on a second carrier on an evolved universal mobile telecommunication system terrestrial radio access system while receiving the multicast service;
informing a source of the second carrier of the multicast subframe allocation pattern of the multicast service;
receiving scheduling grants for subframes with respect to the second carrier, the subframes corresponding to the received scheduling grants being distinct from subframes corresponding to the multicast subframe allocation pattern of the multicast service; and
receiving a second service on the second carrier based on the scheduling grants while receiving the multicast service on the first carrier,
wherein the multicast subframe allocation pattern includes a transmission gap pattern with respect to the multicast service, the transmission gap pattern indicating gaps in a transmission pattern with the first carrier during which a wireless terminal cannot be scheduled a service on the second carrier.
