Abstract: Disclosed are an apparatus and a method for controlling reverse TX power in a mobile terminal. The apparatus includes a closed-loop power controller for limiting a TX power increase due to a power control bit of an RX signal by using a power-up limit bit and outputting a closed-loop power control value for decreasing the TX power when a TX power limit mode is selected, an adder for calculating a TX power by adding the closed-loop power control value and an open-loop power set using a power of the RX signal, and a maximum TX power limiter for setting a final TX power by subtracting a maximum TX power limit reference value determined according to an RX signal strength in the mobile terminal from the calculated TX power. Accordingly, it is possible to extend a call duration while accepting a rather poor call quality.

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.

Abstract: A system and method for converting a note-based audio object to a Pulse Code Modulated (PCM) audio format is disclosed. An electronic communication device includes a memory containing a note-based audio object and lookup table containing trigonometric function evaluations. The note-based audio object contains note frequency information. The note-based audio object is converted to a PCM stream by generating PCM code words for each sample point in the PCM stream based upon the note frequency information. The PCM code words are determined based upon selection of one or more of the trigonometric function evaluations within the look-up table. A speaker outputs audio based upon the PCM formatted stream.
