## Abstract

A method, user equipment (UE) and application server for adding media stream of multimedia session. A UE1 establishes a multimedia session with a UE2, receives a media stream adding request directed at the multimedia session of the UE1; the media stream adding request includes an identity of a UE3 and the media type of the media flow requested to be added; the UE3 is controlled to establish a media stream of the media type with the UE2. Therefore, adding the media stream on the UE3 is realized, and the user may realize the multimedia session with the peer end through multiple UEs, thereby avoiding the inconvenience that the media stream can only be added to the two parties in the session and living up to the users' diversified requirements on the multimedia services.

## Claims

### Claim 1

A method, comprising:
receiving a request from a first user equipment (UE) to establish a media session with the first UE and a second UE, wherein the first UE is associated with a first identifier (ID);
establishing the media session with the first UE and the second UE;
receiving an adding request to add a third UE to the media session, wherein the third UE is associated with the first ID; and
adding the third UE to the media session,
wherein the media session comprises a first media type received from the first UE and a second media type received from the third UE, and
wherein the first media type and the second media type comprise different media types.

### Claim 2 (depends on 1)

The method of claim 1, wherein the first UE and the third UE comprise different terminal devices supporting different media streams.

### Claim 3 (depends on 1)

The method of claim 1, wherein the first media type comprises video, and wherein the second media type comprises audio.

### Claim 4 (depends on 1)

The method of claim 1, wherein the adding request is received from the first UE.

### Claim 5 (depends on 1)

The method of claim 1, wherein the adding request is received from the third UE.

### Claim 6 (depends on 1)

The method of claim 1, wherein the first ID comprises a user name.

### Claim 7 (depends on 1)

The method of claim 1, wherein the first ID comprises an electronic mail address.

### Claim 8 (depends on 1)

The method of claim 1, wherein the first ID comprises a nickname.

### Claim 9

An electronic device, comprising:
a memory configured to store instructions; and
a processor coupled to the memory and configured to execute the instructions to cause the electronic device to:
receive a request from a first user equipment (UE) to establish a media session with the first UE and a second UE, wherein the first UE is associated with a first identifier (ID);
establish the media session with the first UE and the second UE;
receive an adding request to add a third UE to the media session, wherein the third UE is associated with the first ID; and
add the third UE to the media session, wherein the media session comprises a first media type received from the first UE and a second media type received from the third UE, and wherein the first media type and the second media type comprise different media types.

### Claim 10 (depends on 9)

The electronic device of claim 9, wherein the first UE and the third UE comprise different terminal devices supporting different media streams.

### Claim 11 (depends on 9)

The electronic device of claim 9, wherein the first media type comprises video, and wherein the second media type comprises audio.

### Claim 12 (depends on 9)

The electronic device of claim 9, wherein the adding request is received from the first UE.

### Claim 13 (depends on 9)

The electronic device of claim 9, wherein the adding request is received from the third UE.

### Claim 14 (depends on 9)

The electronic device of claim 9, wherein the first ID comprises a user name, an electronic mail address, or a nickname.

### Claim 15 (depends on 9)

The electronic device of claim 9, wherein the electronic device comprises an application server, and wherein the application server is communicatively coupled to the first UE, the second UE, and the third UE.

### Claim 16

A computer program product comprising instructions for storage on a non-transitory computer-readable medium that, when executed by a processor, cause an electronic device to:
receive a request from a first user equipment (UE) to establish a media session with the first UE and a second UE, wherein the first UE is associated with a first identifier (ID);
establish the media session with the first UE and the second UE;
receive an adding request to add a third UE to the media session, wherein the third UE is associated with the first ID; and
add the third UE to the media session, wherein the media session comprises a first media type received from the first UE and a second media type received from the third UE, and wherein the first media type and the second media type comprise different media types.

### Claim 17 (depends on 16)

The computer program product of claim 16, wherein the first UE and the third UE comprise different terminal devices supporting different media streams.
