Abstract: In geographical areas with incomplete Time Division Synchronous Code Division Multiple Access (TD-SCDMA) coverage, it may be beneficial for a multimode User Equipment (UE) to handover to a GSM network, a WCDMA network, a CDMA 1x RTT network, or an LTE network. When multiple networks are available to the UE and a poor signal quality is detected in the TD-SCDMA network, one of the available networks may be selected for inter-RAT handover based on a service type of the active call on the UE. For example, when a circuit-switched call, such as a voice call, is in progress on the UE, an inter-RAT handover to a GSM network occurs. In another example, when a packet-switched call, such as a data call, is in progress on the UE, an inter-RAT handover to a WCDMA network occurs. Selecting a network for inter-RAT handover based on an active call service type improves the service provided to the UE.

Abstract: Uplink synchronization processes in multi-carrier time division-synchronous code division multiple access (TD-SCDMA) systems include determining uplink transmission timing for a first carrier frequency and performing uplink synchronization on the other carrier frequencies based on the transmission timing of the first carrier frequency. The transmission timing may be adjusted based on a timing offset that is measured between the received downlink pilot signals of the various carrier frequencies. User equipment may perform uplink synchronization individually with each of the carriers serviced by a particular Node B after receiving synchronization information regarding those carrier frequencies.

Abstract: Handover processes in multi-carrier carrier time division-synchronous code division multiple access (TD-SCDMA) systems include a two-step handover process. When handover of a user equipment is warranted, a hard handover is performed within a source cell of the system from a first frequency to a second frequency. A baton handover is then performed from the second frequency at the source cell to the second frequency at a target cell. In another aspect, a user equipment receives an assignment of an uplink time slot at a target cell that was selected to prevent the uplink time slot from being proximal to a downlink time slot of a source cell. The user equipment then performs the inter-frequency baton handover using the uplink time slot.

After the subscriber station has entered idle mode, the base station may change at least one paging parameter at the base station. The base station may direct the subscriber station to change at least one paging parameter at the subscriber station after the subscriber station has entered idle mode. The subscriber station may change at least one paging parameter at the subscriber station after the subscriber station has entered idle mode.

Abstract: A base station may generate a subpacket of system overhead messages that is designed so that a subscriber station improves a success rate of decoding the system overhead messages by accumulating multiple received subpackets. The base station may repeatedly broadcast the subpacket to subscriber stations. When a subscriber station receives a subpacket of system overhead messages, the subscriber station may combine the subpacket with previously received subpackets and attempt to decode the system overhead messages from this combination.

Abstract: Certain embodiments of the present disclosure present methods and apparatuses that enable a mobile station (MS) to selectively reject downlink (DL) data during idle mode. The MS may determine whether to reject the pending DL data based on information about the data. This information may be provided by a base station (BS) that is part of the access service network (ASN) that is retaining the DL data. The information provided by the BS may, for instance, include service flow information related to the pending DL data. In certain embodiments, the information may include one or more internet protocol (IP) packets that are part of the pending DL data.
