Problems solved by technology

In the initial stage of service establishment, due to the relatively low user downlink bandwidth caused by FACH flow control, the amount of downlink data will be small within the time range allowed by the node cache, even if the 4A threshold of the FACH user plane is set to 16 bytes (bytes ) (minimum threshold for traffic measurement, defined by the protocol as 8bytes, usually 4B threshold), the amount of data never meets the threshold requirement for triggering 4A events, resulting in longer channel migration delays, eventually leading to mosaic or frame loss Appear

Embodiment Construction

[0032] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0033] refer to figure 1 According to the service bearer channel migration method of the present invention, the method includes the following steps:

[0034] Step S102, initiate a service on the forward access channel.

[0035] The business is a real-time business.

[0036] Step S104, in the initial stage of service establishment, the mobile terminal performs signaling interaction with the network server, and reports the uplink traffic measurement 4A event on the random access channel through the uplink traffic during the signaling interaction process.

[0037] The condition for triggering the migration of the channel carrying the service from the forward access channel to the dedicated transmission channel is the uplink traffic measurement 4A event or the downlink traffic measurement 4A event.

[0038] Optionally, the 4A threshold of the random access channel...

Abstract

The invention discloses a transference method for an operation barer channel. Operation is launched on a forward access channel; at the initial phase after the operation is established, signaling interaction is conducted between a mobile terminal and a network server, and through uplink operation amount of the signaling interaction process, a 4A issue of uplink operation amount measuring is reported to a random access channel, through which the operation bearer channel is beard by the forward access channel and is transferred to a special transmission channel. By adopting the 4A issue of an RACH channel for triggering transference from FACH status to DCH status, the problem of overlong delay of streaming service with a bearer type of I / B is greatly improved, and the service quality is also effectively improved.

Description

technical field [0001] The invention relates to a wideband code division multiple access system in the field of wireless communication, in particular to a service bearer channel migration method. Background technique [0002] In a WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access) system, RRC (Radio Resource Control, Radio Resource Control) performs dynamic radio bearer control by configuring traffic volume measurements (Traffic Volume Measurements). The main principle is: when the business volume measurement value BO (Buffer Occupancy) is greater than a certain threshold 4A Threshold, a 4A event is reported as a trigger for the process of migrating a low-rate radio bearer to a high-rate radio bearer (4A Event) or as a constraint condition for migration. When the service volume measurement value BO (Buffer Occupancy) is less than a certain threshold 4BThreshold, a 4B event is reported to trigger the migration process (4B Event) from a high...
