A system and method for upgrading service class of a connection in a wireless network includes identifying a congested CoS in a sector of a wireless network. Bandwidth availability in the sector is determined at an enhanced CoS in relation to the congested CoS. A communications session is selected in the congested CoS for upgrading. The communications session is upgraded to the enhanced CoS.

System and method for upgrading service class of a connection in a wireless network

A number of associated directory numbers are sequentially correlated into a link list and stored within a telecommunications device, such as a mobile station. In response to a user instruction or pre-determined call setup results, the telecommunications device retrieves a second directory number from the correlated link list and originates another outgoing call connection therewith. As an illustration, the user may provide such an instruction by pressing the volume-up or volume-down key. Alternatively, the mobile station may automatically retrieve and originate a new outgoing call connection using the next directory number from the link list in response to a busy signal from the pending call connection. With repeated detection of such instructions or conditions, the mobile station sequentially and individually retrieves the linked directory numbers and automatically originates outgoing call connections without the user having to separately and inconveniently entering the associated directory numbers.

There is disclosed for use in a wireless network comprising a plurality of base transceiver substations capable of communicating with a plurality of mobile stations, an apparatus for preventing the dropping of an emergency call associated with a first one of the plurality mobile stations. The apparatus comprises a call drop controller for receiving from the wireless network a maintenance command directed to a first base transceiver substation handling the emergency call, determining whether the maintenance command may cause the first base transceiver substation to drop the emergency call and, in response to such a determination, preventing the maintenance command from being executed by the first base transceiver substation. The call drop controller also is capable of: 1) receiving a failure notification from a failed base transceiver substation, 2) determining whether the failed base transceiver substation is handling the emergency call and, 3) in response to such a determination, at least one of: a) increasing transmission power of at least one base transceiver substation proximate to the failed base transceiver substation; b) increasing a TDROP value of the failed base transceiver substation; and 3) decreasing a TADD value of at least one base transceiver substation proximate to the failed base transceiver substation.
