Embodiment Construction
[0131] In order to solve the problems existing in the prior art due to the establishment of the downlink TBF by the MS on the basis of the uplink TBF, multiple time slot reconfigurations, increased signaling consumption, and unbalanced channel occupancy obtained by the MS allocated by the network side, reduce In order to improve the utilization rate of channel resources and affect the efficiency of channel transmission packet data services, an embodiment of the present invention provides a channel allocation method and device for packet data services.
[0132] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0133] refer to figure 2 As shown, the flow of a channel allocation method for a packet data service provided by an embodiment of the present invention specifically includes:
[0134] Step 201: When a PDCH request sent by the MS is received, according to the type of the PDCH request and the ...

The invention discloses a channel allocation method and device for packet data services, which are used to solve the problems of multiple time slot reconfigurations, increased signaling consumption, and unbalanced channel allocation on the network side in the prior art, and reduce the utilization rate of channel resources. , affecting the efficiency of channel transmission packet data services. The method is: when there is no TBF in the opposite channel direction, determine the allocatable time slot schemes of the current channel direction and the reverse channel direction, pass the channel occupancy rate of each allocatable time slot scheme in the current channel direction and the reverse channel direction and The number of occupied time slots is compared to finally determine the target allocation scheme, and the target allocation scheme is selected to establish a TBF in the current channel direction for the MS. In this way, by considering the available channel occupancy rate of the TBF in the current channel direction and the opposite channel direction, the rate of channel transmission packet data service is increased, the number of users that the packet channel can accommodate is increased, and the channel resource utilization rate is improved.
Description
technical field [0001] The invention relates to the communication field, in particular to a channel allocation method and device for packet data services. Background technique [0002] In the general packet radio service (General Packet Radio Service, GPRS) and the extended general packet radio service (Enhanced GPRS, EGPRS) system, the bearer of the packet data service is carried out by establishing a temporary block flow (Temporary Block Flow, TBF). The TBF is a physical connection between the network side and the mobile station, and the establishment of the TBF requires allocation of packet data channel (Packet Data Channel, PDCH) resources through the network side, so as to realize wireless transmission of packet data on the air interface. [0003] Usually, one PDCH can be multiplexed by multiple TBF connections, and one TBF connection can occupy one or more PDCHs. When the PDCH is occupied by a TBF connection, the PDCH bandwidth is occupied by a single user; when the P...
