Embodiment 1

[0042] In Embodiment 1, a new E-DCH non-scheduled authorized service is configured to use the primary carrier or the secondary carrier to carry it. Among them, the terminal has two radio links, both of which belong to the Node B controlled by the serving RNC.

[0043] figure 2 This is the signaling flowchart of Embodiment 1 of the embodiments 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-scheduled authorized service, the secondary carrier frequency is active, the serving RNC determines that it uses the non-scheduled authorized E-DCH transmission, and decides whether the service uses the primary carrier or the secondary carrier based on factors such as the load of the primary and secondary serving cells ;

[0045] Step 202: The serving RNC informs the Node B of the information of using the non-scheduling authorization for the service and whether to use the primary carrier or the second...

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 present invention relates to the field of communication technology, in particular to a non-scheduling authorization allocation method and a radio network controller. Background technique [0002] In the prior art, the goal of the high speed uplink packet access (HSUPA) technology is to improve capacity and data throughput in the uplink direction and reduce the hysteresis in the dedicated channel. A new transmission channel is introduced by HSUPA technology: Enhanced Dedicated Channel (E-DCH). E-DCH improves the physical layer and media access control layer, and can reach the maximum theoretical uplink data rate of 11.52 megabits per second. [0003] At present, services transmitted on E-DCH can use non-scheduling authorization or scheduling authorization. Among them, the services that use non-scheduling authorization are generally signaling and very real-time services. Node B (ie, base station) follows wireless The non-scheduled authorization size requi...
