Method and apparatus for service continuity on a mobile communication device

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.

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.
