Embodiment 1
[0042] Embodiment 1, the new E-DCH non-scheduling authorization service is configured to be carried by the main carrier or the auxiliary carrier, wherein the terminal has two wireless links, both of which belong to the Node B controlled by the serving RNC.
[0043] figure 2 It is a signaling flow chart of Embodiment 1 of the embodiment of the present invention, such as figure 2 As shown, including the following processing:
[0044] Step 201, the terminal creates a new E-DCH non-scheduling authorized service, the auxiliary carrier frequency is activated, the serving RNC determines that it uses the non-scheduling authorized E-DCH transmission, and decides whether the service uses the main carrier or the auxiliary carrier according to factors such as the load of the main and auxiliary serving cells ;
[0045] Step 202, the serving RNC notifies the Node B of the service using the non-scheduling authorization and the information of using the main carrier or the auxiliary carrie...

Abstract
The invention discloses an unscheduled authorized distribution method and a wireless network controller. The method comprises the steps: a wireless network service controller determines that the current service is born by using main carriers or auxiliary carriers according to environmental factor under the condition of determining that the current service uses an enhanced dedicated channel for transmission and uses an unscheduled authorization mode and determining that the auxiliary carrier is positioned in activated state; the wireless network controller carries information transmitted by the current service through using the enhanced dedicated channel, information of unscheduled authorization mode and carrier indication information in preset options of interface signaling and transmits the interface signaling to a node B and a terminal, or the node B, the terminal and the drifting wireless network controller; and the carrier indication information is used for indicating whether the current service is born by using the main carriers or the auxiliary carriers. By means of the technical scheme of the embodiment of the invention, the main carriers can be possible to bear unscheduled authorized service respectively, and the advantages of high capacity in a dual-carrier high-speed uplink packet access can be fully played.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a non-scheduling grant allocation method and a radio network controller. Background technique [0002] In the prior art, the goal of high speed uplink packet access (HSUPA for short) technology is to improve capacity and data throughput in the uplink direction and reduce hysteresis in dedicated channels. A new transmission channel is introduced by HSUPA technology: Enhanced Dedicated Channel (Enhanced Dedicated Channel, referred to as E-DCH). E-DCH improves the physical layer and media access control layer, and can achieve a maximum theoretical uplink data rate of 11.52 megabits per second. [0003] At present, the services transmitted on the E-DCH can use the non-scheduling authorization mode or the scheduling authorization mode. Among them, the services using the non-scheduling authorization are generally services with strong signaling and real-time The size of the non...
