Problems solved by technology

In the SCDMA system that adopts the access channel frame synchronization described above, since the CRC check for the synchronization field SS and the power control field PC is defective in the downlink access code sequence frame structure, then when the wireless signal When the noise ratio is poor and the bit error rate is high, the issued synchronization field SS and power control field PC will be wrong, and when the terminal adjusted according to the wrong SS and PC accesses the base station, the current online Users cause great interference, and in severe cases, it will cause online users to drop calls

Embodiment Construction

[0021] As shown in Fig. 1, in the SCDMA system adopting the QoS processing method of the present invention, after the terminal enters the talking state, the user information is reported through an extended link maintenance frame every predetermined time interval. In the present invention, the predetermined time may be, for example, 220 ms, that is, a link maintenance frame with a length of 22 frames may be completely received. In addition to all the fields of the existing link maintenance frame, the extended link maintenance frame also adds a data type field, a downlink signal-to-noise ratio field and a downlink bit error rate field.

[0022] According to an embodiment of the present invention, the data type field occupies 2 bits, which represents the data type carried in the uplink user message. When the value of this field is 00, it means that the message carries the downlink parameters occupied by the user, such parameters include received signal strength, actual transmissi...

Abstract

This invention relates to a method for processing QoS in a SCDMA wireless communication system including the following steps: 1, a terminal maintains user information reported by frames by a spread link periodically after it enters into a session state, 2, a base station registers down S / N ratio and down error rate reported by the terminal and judges if it has started up the access limit currently, 3, if so, the base station judges if it needs to resume the access system and processes it accordingly based on a preset access resuming rule, 4, if the base station judges that the access limit is not started up currently, it judges if it needs starting up the limit system according to a preset rule of access limit and processes it accordingly, which can realize the maximum combination of session quality and capacitance of base stations.

Description

technical field [0001] The invention relates to a QoS processing method in a wireless communication system, in particular to a QoS processing method in an SCDMA wireless communication system. Background technique [0002] In the patent document entitled "Framing Synchronization Processing Method for Access Channel" (Patent No. ZL02160284.0) describes the method of channel access using frame synchronization in SCDMA system. This patent describes changing asynchronous access to frame-based synchronous access, splitting the original access frame into two parts, access and signaling information, and sending them sequentially. The terminal first sends the access information to obtain the base station After the synchronous adjustment command, send the access signaling information in the next frame to complete the access. [0003] The base station uses the orthogonality of Walsh codes when decoding the received information. When each frame signal is well synchronized, the orthogo...
