    摘要: Aspects of the present invention relate to improved systems and methods for handing over a UE from a source node to a target node. In some embodiments, the target node receives UL and DL count information directly from the UE being handed over, rather than from the source node or from a core network node.

    摘要: A system and method in a wireless communications environment maximizes voice quality in low capacity situations. A Mobile services Switching Centre (MSC) that is associated with a base station of a cell is capable of assigning speech calls of mobile terminals to either a full-rate (FR) or a half-rate (HR) channel. The FR channels provide better transmitted voice quality but consume twice the bandwidth (two time slots versus only one for HR channels). When occupied cell capacity is low, an MSC assigns connections to FR channels. After occupied cell capacity reaches a predetermined threshold value, the MSC assigns connections to HR channels whenever possible. Also, handover procedures can reclaim available capacity by switching a connection from a FR to a HR channel. The superior voice quality of the FR channels are therefore provided to mobile terminal users more often.

    摘要: The present invention is a method and system adapted to facilitate, between a mobile station (MS) and network, an indication of support for reduced time transmission interval (RTTI). The MS can provide a base station system (BSS) with an indication of its multislot capability within an access burst sent at the start of a contention based access. In another aspect, the MS can indicate support for a new Immediate Assignment message as the conventional Immediate Assignment message can only assign single timeslots. The present invention enables the Radio Access Network (RAN) to assign RTTI and more than one timeslot for GPRS/EDGE temporary block flows (TBFs) during an Access Grant Channel (AGCH) assignment. The method of the present invention can be implemented in a computer program product or distributed software adapted to be loaded into at least one or a plurality of memory locations and executed by at least one or a plurality of respective computer processors.
