ABSTRACT:
Various embodiments are described for establishing a group call session serially. After receiving a serial group call request from a remote unit (101), fixed network equipment (FNE) (201) selects a first subset of members (260) from the targeted group (250) of units and signals those members to join the group call session. Various techniques for selecting the first subset may be employed depending on what system benefits are desired. A second subset of members (270) from the targeted group of units is also selected and signaled to join the session. This second subset may be used to invite additional units in order to achieve a maximum number of group participants. Alternatively, the second subset may be used to invite a different unit (or units) to participate. This can be triggered by a user request to invite another subset to the group session, as could occur when the user is not able to resolve the particular matter at-hand with the group members of the first subset.
