That is to say, although this existing implementation scheme can control the uplink load of the cell below the uplink load threshold, it does not give priority to the load demand of GBR users, and it is difficult to meet the QoS requirements of GBR users, which will eventually reduce the HSUPA. performance

Embodiment 1
[0064] Embodiment 1 of the present invention fully considers the QoS requirements of users who have configured GBR, and improves the rate of GBR users by using the original load margin in the cell to reduce the rate of users who have not configured GBR, and the above method cannot meet the requirements of GBR users. When the rate is required, directly set the rate that can meet the GBR rate requirement for the user.
[0065] As shown in Figure 1, the implementation of the first embodiment of the present invention is as follows:
[0066] Step 1. The base station detects whether each user has a request for service quality and GBR rate.
[0067] The base station detects the service quality requirements of all users in the cell, and checks whether the cell users have put forward requirements for guaranteeing service quality and GBR rate, as well as the required GBR rate value.
[0068] Step 2. The base station uses the load margin of the cell to increase the rate of the user conf...
Embodiment 2
[0100] As shown in FIG. 5, a user scheduling system in an uplink enhanced link according to Embodiment 2 of the present invention includes a user equipment, a base station, and a radio network controller,
[0101] The base station includes:
[0102] A rate detection module is used to detect the rates of GBR users and non-GBR users to be scheduled in the cell and their requirements for rates;
[0103] The priority-based rate increase module is used to give priority to increasing the rate of GBR users whose actual rate does not meet the GBR requirement.
[0104] The wireless network controller includes:
[0105] A load detection module, configured to detect whether the uplink load of the cell exceeds the uplink load threshold;
[0106] The quality of service negotiation module is used for negotiating with the user on the quality of service after detecting that the uplink load of the cell exceeds the threshold of the uplink load, so as to reduce the quality of service requireme...

Abstract
This invention provides a user dispatch method and a system in an uplink strengthened link including: a base station tests the rate of GBR and non-GBR users to be dispatched and their requirements on rate, when the rate of the GBR user does not reach that required by the GBR user, then the base station increases the rate of the GBR user in priority. This invention releases part load from the non-GBR user to increase load of the GBR user.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a user scheduling method and system in an uplink enhanced link. Background technique [0002] Uplink High Speed Packet Scheduling (HSUPA) technology is a technology introduced by 3GPP in the WCDMA R6 protocol to increase the uplink transmission rate. This technology adopts NodeB's uplink fast scheduling, hybrid retransmission (HARQ), and 2ms short frame technology, which greatly improves the user's uplink throughput, so as to better develop multimedia services. [0003] The protocol structure of HSUPA is shown in Figure 1. The MAC-es and MAC-e entities in the figure are media access control layer (MAC) entities added after the introduction of HSUPA into the WCDMA system. [0004] In order to support the fast scheduling of the base station (NodeB), the MAC-e entity on the side of the Universal Terrestrial Radio Access Network (UTRAN) is moved down to the...
