Problems solved by technology

According to the calculation results, even if the EGPRS mobile phone monopolizes the downlink resources and the air interface quality can reach the MCS9 coding method, the actual downlink rate of the EGPRS mobile phone is even lower than the rate achievable by the MCS-7 coding method

Embodiment Construction

[0022] When the GPRS mobile phone and the EGPRS mobile phone are multiplexed on the same channel, when the downlink data block of the EGPRS mobile phone contains the USF information of the GPRS mobile phone, if the 8PSK modulation method is used, because the GPRS mobile phone does not support the 8PSK modulation method, the GPRS mobile phone cannot obtain the USF information. USF information, in order to ensure that the GPRS mobile phone can obtain the USF information, the downlink data block of the EGPRS mobile phone carrying the USF information of the GPRS mobile phone cannot completely use the 8PSK modulation method, that is, the downlink data block of the EGPRS mobile phone cannot completely use the 8PSK modulation method. It will cause the downlink rate of the EGPRS mobile phone to fail to reach the ideal value.

Abstract

The embodiment of the invention relates to an assignment method and an assignment device for uplink state flag information of a GPRS mobile phone. The method is that when a GPRS mobile phone and an EGPRS mobile phone are multiplexed on the same channel, the method comprises the following steps that: when uplink state flag information of the GPRS mobile phone is handed out, whether downlink resource of the GPRS exists is judged; if the downlink resource of the GPRS exists, the uplink state flag information of the GPRS mobile phone is carried in a download data block of the GPRS mobile phone to be handed out, or the uplink state flag information of the GPRS mobile phone is carried in the download data block of the GPRS mobile phone or a download data block of the EGPRS mobile phone to be handed out. In the embodiment of the invention, when the mobile phone and the EGPRS mobile phone are multiplexed on the same channel, the uplink state flag information of the GPRS mobile phone is assigned into the download data block of the GPRS mobile phone and the download data block of the EGPRS mobile phone, thereby improving the download rate of the EGPRS mobile phone as a whole.

Description

technical field [0001] The invention relates to the technical field of wireless mobile communication, in particular to a method and a device for distributing uplink state flag information of a GPRS mobile phone. Background technique [0002] According to the description of the radio link control / medium access control (RLC / MAC) protocol, the allocation of uplink packet resources is determined by the network side, and the network side allocates an uplink state flag (Uplink State Flag, USF for short) and Temporary Flow identity (TFI for short). After the mobile phone requests the uplink Temporary Block Flow (TBF for short), it starts to monitor each downlink data block on the channel (group), and the MAC header of each downlink data block (including the signaling block) sent by the network side Both contain USF. The mobile phone judges whether the USF in the downlink data block is the same as the USF allocated to itself, and if so, sends the uplink data block at the next upli...
