Point to Point and Point to Multipoint Switching with Service Continuity for Broadcast and Multicast Service

A baseband processor configured to perform operations comprising:

• receiving first configuration information from a cellular base station of a cellular network, wherein the first configuration information is associated with a first over-the-air delivery type for a multicast service;
• receiving first data of the multicast service from the cellular base station using the first over-the-air delivery type in accordance with the first configuration information;
• receiving second configuration information from the cellular base station, wherein the second configuration information is associated with a second over-the-air delivery type for the multicast service, wherein the second configuration information includes information useable for switching delivery of the multicast service from the first over-the-air delivery type to the second over-the-air delivery type;
• providing, to the cellular base station in conjunction with said switching delivery of the multicast service from the first over-the-air delivery type to the second over-the-air delivery type, context information;
• and
• receiving second data of the multicast service from the cellular base station using the second over-the-air delivery type in accordance with the second configuration information.

A method, comprising:

• transmitting, to a wireless device, first configuration information, wherein the first configuration information is associated with a first over-the-air delivery type for a multicast service;
• transmitting, to the wireless device, second configuration information, wherein the second configuration information is associated with a second over-the-air delivery type for the multicast service, wherein the second configuration information includes information useable for switching delivery of the multicast service from the first over-the-air delivery type to the second over-the-air delivery type;
• and
• transmitting, to the wireless device, the multicast service using the second over-the-air delivery type in accordance with the second configuration information.

A method, comprising:

• receiving first configuration information from a cellular base station of a cellular network, wherein the first configuration information is associated with a first over-the-air delivery type for a multicast service;
• receiving first data of the multicast service from the cellular base station using the first over-the-air delivery type in accordance with the first configuration information;
• receiving second configuration information from the cellular base station, wherein the second configuration information is associated with a second over-the-air delivery type for the multicast service, wherein the second configuration information includes information useable for switching delivery of the multicast service from the first over-the-air delivery type to the second over-the-air delivery type;
• providing, to the cellular base station in conjunction with said switching delivery of the multicast service from the first over-the-air delivery type to the second over-the-air delivery type, context information;
• and
• receiving second data of the multicast service from the cellular base station using the second over-the-air delivery type in accordance with the second configuration information.
