An arrangement and method in a wireless communication network provides users with full control of service management, defines how a user can enter or leave services, and defines dependencies between services. A mobile terminal initiates establishment of a group and creates a unique groupID. The terminal sends invitations to other terminals to join the group and includes the unique groupID and a service feature tag for a desired service. The terminal will not request a service if it is incompatible with a service already running. Terminals that receive invitations store the groupID and service feature tags. These parameters are used to send acceptances or rejections, and to join later or leave a service.
