Abstract

An apparatus includes at least one memory including computer program code and at least one processor. The at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to receive a message containing no media content, the message indicating one or more supported media types by a group, cross-check the indicated supported media types with usable media types in the group, based on the cross-check, determine whether at least one of the indicated supported media types is found in the usable media types in the group and, based on the determination, send the message without modifying the indicated supported media types if all of the indicated supported media types are determined to be usable media types.

Claims

1. An apparatus comprising:

at least one memory including computer program code; and

at least one processor; and

wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to;

receive a message containing no media content, the message indicating one or more supported media types by a group;

cross-check the indicated supported media types with usable media types in the group;

based on the cross-check, determine whether at least one of the indicated supported media types is found in the usable media types in the group; and

based on the determination, send the message without modifying the indicated supported media types if all of the indicated supported media types are determined to be usable media types.

2. The apparatus of claim 1, wherein the usable media types comprise at least one group of:

defined supported media types by the group, allowable media types of a group member, group member capabilities of a group member, and user equipment capabilities of user equipment used by a group member.

3. The apparatus of claim 1, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus at least to:

cross-check the indicated supported media types with defined supported media types; and

modify the message to include a defined supported media type missing from the message as the indicated supported media type.

4. The apparatus of claim 1, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus at least to:

cross-check the indicated supported media types with defined supported media types; and

remove from the message an indicated supported media type that is not included in the defined supported media type for the group.

5. The apparatus of claim 1, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus at least to:

cross-check the indicated supported media types with allowable media types of a group member; and

remove from the message an indicated supported media type that is not included in the allowable media types of the group member.

6. The apparatus of claim 5, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus at least to send the message as a customized message to the group member.

7. The apparatus of claim 1, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus at least to:

cross-check the indicated supported media types with group member capabilities of a group member; and

remove from the message an indicated supported media type that is not supported by the group member capabilities.

8. The apparatus of claim 1, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus at least to:

cross-check the indicated supported media types with user equipment capabilities of user equipment used by a group member; and

remove from the message an indicated supported media type that is not supported by the user equipment capabilities.

9. An apparatus, comprising:

at least one memory including computer program code; and

at least one processor; and

wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to;

receive a message, the message including at least one of an advertisement of a group and an invitation to group members to join a group, the message containing no indication of one or more supported media types by the group; and

based on the message, add an indication of group-specific supported media types to the message.

10. An apparatus comprising:

at least one memory including computer program code; and

at least one processor; and

wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to;

receive a message containing no media content, the message indicating one or more supported media types by a group;

compare the indicated one or more supported media types with capabilities of the apparatus;

based on the comparison, determine whether the indicated one or more supported media types are supported by the capabilities of the apparatus; and

show the message to a user if all of the indicated one or more supported media types are supported by the capabilities of the apparatus.

11. The apparatus of claim 10, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus at least to remove from the message an indicated supported media type that is not supported by the capabilities.

12. A method comprising:

receiving, by an apparatus supporting group communication, a message containing no media content, the message indicating one or more supported media types by a group;

comparing, in response to the message, the indicated one or more supported media types to one or more media types defined to be usable by the group;

based on the comparison, determining whether the indicated one or more supported media types can be found in the defined usable media types; and

determining how to continue based on the comparison.

13. The method of claim 12, wherein the method further comprises adding, with the apparatus, to the message a defined supported media type not included in the message as an indicated supported media type;

and

wherein the comparison comprises comparing the indicated supported media types with defined supported media types.

14. The method of claim 12, further comprising removing from the message an indicated supported media types with defined supported media types;

and wherein

the comparison comprises comparing the indicated supported media types to defined supported media types.

15. The method of claim 12, further comprising:

removing from the message an indicated supported media type that is not included in the allowable media types of a group member; and

wherein the comparison comprises comparing the indicated supported media types to allowable media types of a group member.

16. The method of claim 12, further comprising:

removing from the message an indicated supported media type that is not supported by group member capabilities; and

wherein the comparison comprises comparing the indicated supported media types to capabilities of a group member.

17. The method of claim 12, further comprising:

removing from the message an indicated supported media type that is not supported by user equipment capabilities; and

wherein the comparison comprises comparing the indicated supported media types to capabilities of user equipment used by a group member.

18. The method of claim 12, further comprising sending the message to one or more group members and/or showing the message to a user if the message contains at least one indicated supported media type by the group.

19. The method of claim 12, further comprising ignoring the message if the message does not contain an indicated supported media type after cross-checking.

20. A computer program product embodied in a device-readable non-transitory medium and comprising program instructions, wherein execution of the program instructions causes a device containing the computer program product to perform a process, the process comprising:

receiving a message containing no media content and indicating at least one supported media type by a group;

comparing, in response to receiving the message, the indicated at least one supported media type with media types defined to be usable by the group;

determining, based on the comparison, whether the indicated at least one supported media type is found in the defined usable media types; and

deciding how to continue based on the comparison.
