Abstract

Claims (64)

1. A method performed by a mission critical (MC) gateway (GW) user equipment (UE) supporting a multimedia broadcast multicast services (MBMS) in a wireless communication system, the method comprising:

receiving, from an MC client, an MC GW MBMS bearer announcement including MBMS bearer related information;

storing information associated with at least one temporary mobile group identity (TMGI);

activating a monitoring of an MBMS bearer based on the at least one TMGI and other MBMS bearer related information;

transmitting, to the MC client, an MC GW MBMS listening status report including non-3 rd generation partnership project (3GPP) transport resources related parameters, wherein transport resources are established between the MC client and the MC GW UE based on the non-3GPP transport resources related parameters;

receiving, from an MC service server, MC service data over the MBMS bearer; and

forwarding, to the MC client, the MC service data over the transport resources,

wherein the MC client resides on a non-3GPP device.

2. The method of claim 1 , wherein service description information associated with the MBMS bearer is provided from the MC service server to the MC client residing on the non-3GPP device via the MC GW UE.

3. The method of claim 1 , further comprising:

receiving, from the MC client, an MBMS listening status report, wherein the MBMS listening status report indicates that the MC client is able to receive media over MBMS; and

transmitting, to the MC service server, the MBMS listening status report.

4. The method of claim 1 , wherein the MC client has been configured with necessary parameters to enable a use of the MC GW UE.

5. The method of claim 1 ,

wherein the MC GW MBMS bearer announcement includes at least one of an MC GW service identifier (ID), a TMGI, a list of service area identifier, a frequency, session description protocol (SDP) information, a monitoring state, or robust header compression (ROHC) information, and

wherein the MC GW MBMS listening status report includes at least one of a TMGI, an MBMS listening status, an MBMS reception quality level, or non-3GPP transport channel establishment parameters.

6. A method performed by a mission critical (MC) client supporting a multimedia broadcast multicast services (MBMS) in a wireless communication system, the method comprising:

sending, to an MC gateway (GW) user equipment (UE), an MC GW MBMS bearer announcement including MBMS bearer related information;

receiving, from the MC GW UE, an MC GW MBMS listening status report including non-3rd generation partnership project (3GPP) transport resources related parameters, wherein transport resources are established between the MC client and the MC GW UE based on the non-3GPP transport resources related parameters; and

receiving, from the MC GW UE, MC service data over the transport resources, wherein the MC service data is received over an MBMS bearer from an MC service server,

wherein a monitoring of the MBMS bearer is activated based on at least one temporary mobile group identity (TMGI) and other MBMS bearer related information, and

wherein the MC client resides on a non-3GPP device.

7. The method of claim 6 , further comprising:

receiving, from the MC service server, service description information associated with the MBMS bearer.

8. The method of claim 6 , further comprising:

transmitting, to the MC service server, an MBMS listening status report, wherein the MBMS listening status report indicates that the MC client is able to receive media over MBMS.

9. The method of claim 6 , wherein the MC client has been configured with necessary parameters to enable an use of the MC GW UE.

10. The method of claim 6 ,

wherein the MC GW MBMS bearer announcement includes at least one of an MC GW service identifier (ID), a temporary mobile group identity (TMGI), a list of service area identifier, a frequency, session description protocol (SDP) information, a monitoring state, or robust header compression (ROHC) information, and

wherein the MC GW MBMS listening status report includes at least one of a TMGI, an MBMS listening status, an MBMS reception quality level, or non-3GPP transport channel establishment parameters.

11. A mission critical (MC) gateway (GW) user equipment (UE) supporting a multimedia broadcast multicast services (MBMS) in a wireless communication system, the MC gateway UE comprising:

a transceiver; and

a controller coupled with the transceiver, and configured to:

receive, from an MC client, an MC GW MBMS bearer announcement including MBMS bearer related information,

store information associated with at least one temporary mobile group identity (TMGI),

transmit, to the MC client, an MC GW MBMS listening status report including non-3 rd generation partnership project (3GPP) transport resources related parameters, wherein transport resources are established between the MC client and the MC GW UE based on the non-3GPP transport resources related parameters,

receive, from an MC service server, MC service data over the MBMS bearer, and

forward, to the MC client, the MC service data over the transport resources,

wherein the MC client resides on a non-3GPP device.

12. The MC gateway UE of claim 11 , wherein service description information associated with the MBMS bearer is provided from the MC service server to the MC client residing on the non-3GPP device via the MC GW UE.

13. The MC gateway UE of claim 11 , wherein the controller is further configured to:

receive, from the MC client, an MBMS listening status report, wherein the MBMS listening status report indicates that the MC client is able to receive media over MBMS, and

transmit, to the MC service server, the MBMS listening status report.

14. The MC gateway UE of claim 11 , wherein the MC client has been configured with necessary parameters to enable a use of the MC GW UE.

15. The MC gateway UE of claim 11 ,

wherein the MC GW MBMS bearer announcement includes at least one of an MC GW service identifier (ID), a TMGI, a list of service area identifier, a frequency, session description protocol (SDP) information, a monitoring state, or robust header compression (ROHC) information, and
