Apparatuses, method, and computer-program for a mobile telecommunication network comprising multiple public land mobile networks sharing a radio access network node are provided. An apparatus of one of the multiple public land mobile networks may include at least one processor; and at least one memory comprising: instructions which, when executed by the at least one processor cause the apparatus at least to: receive, from an application function of a content provider, a request for allocation of a temporary mobile group identity for a shared multicast/broadcast session comprising an index value to be used to select a temporary mobile group identity for the shared multicast/broadcast service from the list of temporary mobile group identities for shared services; select, based on the index value, a temporary mobile group identity for the shared multicast/broadcast service from a list or range of temporary mobile group identities for shared services; and send, to the application function, the selected temporary mobile group identity for the shared multicast/broadcast service.
