## Abstract

Embodiments of the present disclosure provide methods and apparatuses for location based group formation. A method performed by a group management server comprises receiving a location based group creation request from a group management client or a vertical application layer (VAL) server. The location based group creation request comprises location information and at least one VAL service identity (ID). The method further comprises obtaining information of at least one VAL user and/or at least one VAL user equipment (UE) corresponding to the location information. The method further comprises obtaining VAL service data of the at least one VAL user and/or the at least one VAL UE. The method further comprises creating a location based group matching the location based group creation request based on the VAL service data of the at least one VAL user and/or at least one VAL UE.

## Claims

### Claim 10 (depends on 7)

The method according to claim 7, wherein
when the second request comprises one or more VAL service IDs, the one or more VAL service IDs are used as a first service data retrieval filter and the second response comprises the VAL service data filtered by the first service data retrieval filter,
when the second request comprises one or more VAL user IDs and/or one or more VAL UE IDs, the one or more VAL user IDs and/or the one or more VAL UE IDs are used as a second service data retrieval filter and the second response comprises the VAL service data filtered by the second service data retrieval filter,
when the second request comprises both the one or more VAL service IDs and the one or more VAL user IDs and/or the one or more VAL UE IDs, the one or more VAL service IDs and the one or more VAL user IDs and/or the one or more VAL UE IDs are used as a third service data retrieval filter and the second response comprises the VAL service data filtered by the third service data retrieval filter.
