摘要： A method for scheduling messages transmitted on a forward common channel of a CDMA system. The method includes determining the ratio between the slotted and unslotted messages transmitted over the forward common channel over a period of time. For each time slot S(i) of the forward common channel, s % time is allocated from the duration of the time slot to slotted messages and u % time is allocated from the duration of the time slot to unslotted messages. The s % time and u % time are determined based on the ratio between the slotted and unslotted messages transmitted over the forward common channel over a period of time.

摘要： Data traffic over a plurality of data communications links of a wireless data communications system is controlled by identifying a poorly performing wireless link, and interrupting data communications over the poorly performing link. The data throughput of remaining links between the transceivers is thus increased due to reduced interference and increased available band-width, because the poorly performing link is no longer transmitting. Interruption of data communications over the poorly performing link may be accomplished by suspending or dropping transmission of a frame. If a frame is predicted to be certain to violate quality of service (QoS) requirements, the frame may be preemptively suspended or dropped. If multiple frames are dropped within a predetermined period, a communications session over the poorly performing link may be dropped. Data communications over the poorly performing link can be resumed following a selected delay period, which may have a random length.

摘要： A method of controlling the performance of a radio link between a base transceiver station and a radio terminal for a wireless transmission system is provided. A radio network controller (RNC) monitors a directly observable L-2 parameter, and determines a without explicit L2-L1 signaling a threshold violation by the L-1 parameter for accordingly triggering a status change of the radio link. Namely, a L-2 radio resource management algorithm prompts the radio terminal and the RNC to perform a radio resource management action whenever the L-1 parameter violates a L-1 threshold. Such an action could be directly downgrading or upgrading the transmission rate on the radio link, or a radio link reconfiguration. The L-1 parameter may be the radio block error rate r, and the L-2 parameter may be the PDU retransmission rate R.

摘要： A scheduler performs per sub-band prioritization allocation of sub-bands to user terminals to generate a pre-allocation schedule. The prioritization is performed independently for each sub-band. The resulting pre-allocation schedule indicates the relative priorities of the user terminals for each sub-band taking into account the channel conditions and specific needs of the user terminals. Based on the pre-allocation schedule, the scheduler can more efficiently allocate the radio resources to the user terminals based on the channel conditions and the specific needs of the user terminals. The scheduling approach is suitable for parallel computing architectures. The use of a parallel computing architecture increases MIPS (million instructions per second) capacity and allows faster scheduling in order to meet stringent real-time constraints.

摘要： A system and method manages Radio Access Network (RAN) resources to service packet data transmissions at Service Quality Levels (SQL) commensurate with packet data network SQLs. A Packet Data Serving Node (PDSN) receives a data packet from a coupled packet data network. The data packet is directed toward a Mobile Station (MS) serviced by the RAN and includes a packet SQL indicator that indicates the level of service provided by the data packet network. A corresponding set of RAN resources is allocated to meet the packet SQL indicator. If the set of RAN resources cannot be allocated, the data packet SQL indicator is remarked accordingly. In another operation, the BSC receives a data packet from a MS serviced by the RAN. The data packet is intended for a coupled packet data network and includes a packet SQL indicator. The BSC first determines a set of allocated RAN resources that are servicing the transmission of the data packet to the packet data network. The BSC then maps the allocated set of RAN resources to a RAN service quality level indicator. If the data packet SQL indicator is incorrectly marked, it is remarked by the PDSN. These operation provide support for both specific SQL operations and differential SQL operations.
