Abstract

A method for broadcasting a short message service (SMS) payload is disclosed. The SMS payload is sent to a home network. The SMS payload is encapsulated in a session initiation protocol (SIP) message. The SIP message is sent to a target user equipment (UE). A SIP response is received from the target UE. The SMS payload is extracted from the SIP message. The SMS payload is broadcasted to a plurality of mobile stations.

Claims

1. A method for broadcasting a short message service (SMS) payload, comprising:

receiving at a receiver, a SIP message having encapsulated therein an SMS payload and a target SMS user list, the target SMS user list indicating a group of mobile stations to which the SMS payload is to be sent, the group of mobile stations being associated with a group identifier;

exploding the target SMS user list;

consulting a static table to map the target SMS user list to a multicast IP address associated with the group identifier;

modifying the SIP message by removing the target user list;

generating a modified SIP message addressed to the multicast IP address; and

transmitting the modified SIP message to a broadcast base station controller (BBCS) for creating a new broadcast flow for broadcasting the SMS payload and allocating only a single channel for broadcasting the SMS payload to the group of mobile stations.

2. The method of claim 1, wherein each mobile station in the group of mobile stations is pre-provisioned to the multicast IP address.

3. The method of claim 1, wherein an ANSI-41 network sends the SMS payload to a home network.

4. The method of claim 1, wherein the BBSC broadcasts a broadcast overhead message (BOM) comprising broadcast multicast service flow identification (BCMCS Flow ID) and channel information.

5. The method of claim 1, further comprising verifying if the BBSC is registered on an IP Multimedia subsystem (IMS).

6. The method of claim 1, wherein the new broadcast flow includes a BCMCS Flow ID identifying the multicast IP address associated with the group identifier.

7. The method of claim 1, further comprising:

extracting the SMS payload from the SIP message;

encapsulating the extracted SMS payload into a broadcast message; and

broadcasting the encapsulated SMS payload to each mobile station in the group of mobile stations over the single allocated channel using the created broadcast flow.

8. The method of claim 7, further comprising broadcasting the SMS payload to the plurality of mobile stations using code division multiple access 1×

evolution data optimization (CDMA 1×

EV-DO).

9. A non-transitory computer readable medium having stored thereon a set of instructions executable to:

receive a session initiation protocol (SIP) message having encapsulated therein an SMS payload and a target SMS user list, the target SMS user list indicating a group of mobile stations to which the SMS payload is to be sent, the group of mobile stations being associated with a group identifier;

explode the target SMS user list;

consult a static table to map the target SMS user list to a multicast IP address associated with the group identifier;

modify the SIP message by removing the target user list;

generate a modified SIP message addressed to the multicast IP address; and

transmit the modified SIP message to a broadcast base station controller (BBSC) for creating a new broadcast flow for broadcasting the SMS payload and allocating only a single channel for broadcasting the SMS payload to the group of mobile stations.

10. The non-transitory computer readable medium of claim 9, wherein the new broadcast flow includes a BCMCS Flow ID identifying the multicast IP address associated with the group identifier.

11. The non-transitory computer readable medium of claim 9, wherein the instructions are further executable to:

extract the SMS payload from the SIP message;

encapsulate the extracted SMS payload into a broadcast message; and

broadcast the encapsulated SMS payload to each mobile station in the group of mobile stations over the single allocated channel using the created broadcast flow.

12. The non-transitory computer readable medium of claim 11, wherein the instructions are further executable to use code division multiple access 1×

evolution data optimization (CDMA 1×

EV-DO) to broadcast the SMS payload to the plurality of mobile stations.

13. A system that is configured to broadcast a short message service (SMS) payload comprising:

means for receiving a SIP message having encapsulated therein an SMS payload and a target SMS user list indicating a group of mobile stations to which the SMS payload is to be sent, the group of mobile stations being associated with a group identifier;

means for exploding the target SMS user list;

means for consulting a static table to map the target SMS user list to a multicast IP address associated with the group identifier;

means for modifying the SIP message by removing the target user list;

means for generating a modified SIP message addressed to the multicast IP address; and

means for transmitting the modified SIP message to a broadcast base station controller (BBCS) for creating a new broadcast flow for broadcasting the SMS payload and allocating only a single channel for broadcasting the SMS payload to the group of mobile stations.
