Embodiment 1

[0078] This embodiment describes in detail the first method for selecting an uplink transmission channel provided by the present invention, that is, the method for selecting an uplink transmission channel for an enhanced UE by the network side.

[0079] As mentioned above, in the first method provided by the present invention, the network side selects and configures an uplink transmission channel for the enhanced UE according to the guaranteed rate and priority of the service of the enhanced UE, specifically :

[0080] A high guaranteed rate threshold, a low guaranteed rate threshold, a high priority threshold, and a low priority threshold may be preset; the high guaranteed rate threshold is greater than the low guaranteed rate threshold, and the high priority threshold is greater than the low priority threshold;

[0081] And follow the following principles when making channel selection:

[0082] Configure the enhanced UE with single signaling bearer service on RACH;

[0083...

Embodiment 2

[0108] This embodiment describes in detail the second and third methods for selecting an uplink transmission channel provided by the present invention. Among them, in the second method, the specific implementation of selecting the uplink transmission channel for the enhanced UE by the network side has been described in detail in the first embodiment. The method of uplink transmission channel.

[0109] As mentioned above, in the method for selecting an uplink transmission channel by the enhanced UE provided by the present invention, the enhanced UE periodically selects the uplink transmission channel according to the arrival rate and buffer size of the current business, specifically:

[0110] Arrival rate threshold, buffer threshold and channel selection cycle can be set in advance;

[0111] And proceed as follows when performing channel selection:

[0112] Start a timer whose timing duration is the channel selection period;

[0113] When the timer expires, if the arrival ra...

Abstract

The invention discloses a method for selecting an uplink transmission channel. The method comprises the following steps: enhanced type UE in a CELL-FACH state is set in advance, and E-DCH and RACH are supported simultaneously; when channel configuration is needed to be carried out on the enhanced type UE, a network side selects and configures an uplink transmission channel for the enhanced type UE according to the guarantee rate and the priority level of the service of the enhanced type UE; and when the service is carried out, the enhanced type UE in the CELL-FACH state periodically selects the uplink transmission channel according to the arrival rate and the buffer memory quantity of the service which is currently carried out. By applying the invention, RACH and E-DCH resources can be reasonably configured.

Description

technical field [0001] The invention relates to high-speed packet access (HSPA) technology, in particular to a method for selecting an uplink transmission channel. Background technique [0002] In the HSPA system, user equipment (UE) has two basic operation modes: idle mode and connected mode. After the UE is powered on, it enters the idle mode; when the UE in the idle mode receives paging from the system or receives a request from the upper layer to establish a radio resource control (RRC) connection, it completes the establishment of the RRC connection and transfers from the idle mode to the connected mode; Transition from connected mode to idle mode when the RRC connection is released. [0003] In connection mode, UE has four states: CELL_FACH state, CELL_DCH state, CELL_PCH state and URA_PCH state. The different states reflect the connection level of the UE and which transport channels the UE can use. Time Division Synchronous Code Division Multiple Access (TD-SCDMA) ...
