Method and apparatus multimedia broadcast/multicast service coverage boost
First Claim
1. A method of assigning Multimedia Broadcast Multicast Service (E-MBMS) bearers in a Multimedia Broadcast Single Frequency Network (MBSFN) area in a Third Generation Partnership Project (3GPP) compliant wireless communication system, the method comprising:
- an infrastructure device operably coupled to the 3GPP compliant system, the 3GPP compliant system having a radio access network comprising one or more MBSFN areas, wherein each MBSFN area supports a plurality of E-MBMS bearers for transporting media streams to user equipments (UE), the infrastructure device using application layer processing to perform;
receiving information from a UE, the information comprising;
an identifier that identifies at least a primary preferred MBSFN area for providing transmissions to the UE;
a request for a boost to the quality of the transmissions received by the UE;
using a first E-MBMS bearer and a second E-MBMS bearer in an MBSFN area, to support a call to the UE, the first E-MBMS bearer providing a first media content stream to the UE and the second E-MBMS bearer providing a second media content stream to the UE, the first media content stream and the second media content stream comprising the same information.

Abstract
A method of assigning Multimedia Broadcast Multicast Service (E-MBMS) bearers in a Multimedia Broadcast Single Frequency Network (MBSFN) area in a 3GPP compliant wireless communication system is provided. An infrastructure device is operably coupled to a radio access network comprising one or more MBSFN areas, wherein each MBSFN area supports a plurality of E-MBMS bearers for transporting media streams to user equipments (UE). The infrastructure device receives, from a UE, an identifier of a preferred MBSFN area and a request for a boost to the quality of the transmissions. The infrastructure device assigns first and second E-MBMS bearers in an MBSFN area to support a call to the UE, the first and second E-MBMS bearers providing the same information to the UE in their media content streams. The UE may employ application layer time-diversity reception of the media content.

14. A method for a User Equipment (UE) to receive an E-MBMS service in a Third Generation Partnership Project (3GPP) compliant wireless communication system, the 3GPP compliant system having a radio access network comprising one or more MBSFN areas, wherein each MBSFN area supports a plurality of E-MBMS bearers for transporting media streams to user equipments (UE), the method comprising a UE performing:
-
receiving at least two media content streams comprising the same information in an MBSFN area, a first media content stream being received on a first E-MBMS bearer and a second media content stream being received on a second E-MBMS bearer; time aligning the at least two media content streams; using header information to detect missing packets from each of the at least two media content streams; combining packets from each of the at least two media content streams, to construct a single media content stream with the information. - View Dependent Claims (15)

16. A method for a User Equipment (UE) to provide Multimedia Broadcast/Multicast Service (E-MBMS) service area location update information to an infrastructure device in a Third Generation Partnership Project (3GPP) compliant wireless communication system, the 3GPP compliant system having a radio access network comprising one or more MBSFN areas, wherein each MBSFN area provides an E-MBMS transmission and supports a plurality of E-MBMS bearers for transporting media streams to user equipments (UE), the method comprising a UE configured for multiple MBSFN reception using application layer processing to perform:
-
receiving a transmission from an MBSFN area, the transmission comprising an identifier of the MBSFN area; transmitting information to an infrastructure device operably coupled to the 3GPP compliant system, the information comprising; the identifier that identifies the MBSFN area; and at least one of; a request for a boost to the quality of the transmissions received by the UE; a request for a call to be processed as an emergency call; receiving a call on a first E-MBMS bearer and a second E-MBMS bearer in the MBSFN area, the call being provided to a call group comprising the UE, the first E-MBMS bearer providing a first media content stream to the UE and the second E-MBMS bearer providing a second media content stream to the UE, wherein the first media content stream and the second media content stream comprise the same call information. - View Dependent Claims (17, 18, 19, 20)
