## Abstract

Methods and apparatuses are disclosed for enhancement to an internet protocol (IP) multimedia subsystem (IMS). According to an embodiment, an application server (AS) of the IMS receives from a terminal device a first request for initiating a call service and an internet service which are to be integrated with each other. The AS of the IMS sends a second request for initiating the internet service to a gateway server that acts as a gateway to an internet AS capable of providing the internet service. In response to a reply from the gateway server, the AS of the IMS handles the first request based on the reply.

## Claims

### Claim 1

A method implemented at a multimedia resource function processor (MRFP) of an internet protocol (IP) multimedia subsystem (IMS), the method comprising:
receiving, from an application server (AS) of the IMS, an instruction for integrating a call service with an internet service, wherein the instruction comprises direction information for the internet service indicating a direction for media relative to an internet AS capable of providing the internet service, and model information for the internet service indicating how the MRFP is to integrate the media; and
integrating the call service with the internet service based on the instruction.

### Claim 2 (depends on 1)

The method of claim 1,
wherein the direction information indicates, for the internet service:
uploading the media from the MRFP to the internet AS capable of providing the internet service;
downloading the media from the internet AS to the MRFP; or
a combination of the uploading and the downloading the media; and
wherein the model information indicates, for the internet service:
mixing media from the call service with the media downloaded from the internet AS;
performing the uploading and/or the downloading of the media for one party of the call service; or
performing the uploading and/or the downloading of the media for two parties of the call service.

### Claim 3 (depends on 2)

The method of claim 2 wherein the direction information is indicated by at least one of:
a SendReceive command;
a SendOnly command; and
a ReceiveOnly command.

### Claim 4 (depends on 2)

The method of claim 2 wherein to integrate the call service with the internet service based on the instruction, the MRFP is controlled to mix the media from the call service with the media from the internet AS based on a media model comprised in the instruction.

### Claim 5 (depends on 2)

The method of claim 2 wherein to integrate the call service with the internet service based on the instruction, the MRFP is controlled to retransmit the media based on a media model comprised in the instruction.

### Claim 6 (depends on 1)

The method of claim 1 wherein the MRFP is controlled by the AS of the IMS via a media gateway control protocol (MEGACO).

### Claim 7

A multimedia resource function processor (MRFP) of an internet protocol (IP) multimedia subsystem (IMS), the MRFP comprising:
processing circuitry; and
memory comprising instructions executable by the processing circuitry, whereby the MRFP is configured to:
receive, from an application server (AS) of the IMS, an instruction for integrating a call service with an internet service, wherein the instruction comprises direction information for the internet service indicating a direction for media relative to an internet AS capable of providing the internet service, and model information for the internet service indicating how the MRFP is to integrate the media; and
integrate the call service with the internet service based on the instruction.

### Claim 8 (depends on 7)

The MRFP of claim 7,
wherein the direction information indicates, for the internet service:
uploading the media from the MRFP to the internet AS capable of providing the internet service;
downloading the media from the internet AS to the MRFP; or
a combination of the uploading and the downloading the media; and
wherein the model information indicates, for the internet service:
mixing media from the call service with the media from the internet AS;
performing the uploading and/or the downloading of the media for one party of the call service; or
performing the uploading and/or the downloading of the media for two parties of the call service.

### Claim 9 (depends on 8)

The MRFP of claim 8 wherein the direction information is indicated by at least one of:
a SendReceive command;
a SendOnly command; and
a ReceiveOnly command.

### Claim 10 (depends on 8)

The MRFP of claim 8 wherein to integrate the call service with the internet service based on the instruction, the MRFP is configured to mix the media from the call service with the media from the internet AS based on a media model comprised in the instruction.

### Claim 11 (depends on 8)

The MRFP of claim 8 wherein to integrate the call service with the internet service based on the instruction, the MRFP is configured to retransmit the media based on a media model comprised in the instruction.

### Claim 12 (depends on 7)

The MRFP of claim 7 wherein the MRFP is controlled by the AS of the IMS via a media gateway control protocol (MEGACO).

### Claim 13

A non-transitory computer readable medium storing computer program code thereon that, when executed by processing circuitry of a multimedia resource function processor (MRFP) of an internet protocol (IP) multimedia subsystem (IMS), causes the MRFP to:
receive, from an application server (AS) of the IMS, an instruction for integrating a call service with an internet service, wherein the instruction comprises direction information for the internet service indicating a direction for media relative to an internet AS capable of providing the internet service, and model information for the internet service indicating how the MRFP is to integrate the media; and
integrate the call service with the internet service based on the instruction.

### Claim 14 (depends on 13)

The non-transitory computer readable medium of claim 13,
wherein the direction information indicates, for the internet service:
uploading the media from the MRFP to the internet AS capable of providing the internet service;
downloading the media from the internet AS to the MRFP; or
a combination of the uploading and the downloading the media; and
wherein the model information indicates, for the internet service:
mixing media from the call service with the media from the internet AS;
performing the uploading and/or the downloading of the media for one party of the call service; or
performing the uploading and/or the downloading of the media for two parties of the call service.

### Claim 15 (depends on 14)

The non-transitory computer readable medium of claim 14 wherein the direction information is indicated by at least one of:
a SendReceive command;
a SendOnly command; and
a ReceiveOnly command.

### Claim 16 (depends on 14)

The non-transitory computer readable medium of claim 14 wherein to integrate the call service with the internet service based on the instruction, the MRFP is further caused to mix the media from the call service with the media from the internet AS based on a media model comprised in the instruction.

### Claim 17 (depends on 14)

The non-transitory computer readable medium of claim 14 wherein to integrate the call service with the internet service based on the instruction, the MRFP is further caused to retransmit the media based on a media model comprised in the instruction.

### Claim 18 (depends on 13)

The non-transitory computer readable medium of claim 13 wherein the MRFP is controlled by the AS of the IMS via a media gateway control protocol (MEGACO).
