Problems solved by technology

[0021] The present invention provides a kind of bandwidth distribution method, system and wireless network controller, in order to solve the WCDMA system of the prior art when the user calls and establishes the wireless link and just actually inquires and distributes the transmission bandwidth of the Iub port, resulting in call establishment failure and call rejection delay, It is impossible to improve the connection rate of the system according to the business type, and it is unable to meet the access requests of high-priority users in time and provide differentiated services.

Embodiment Construction

[0073] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0074] The concept of the present invention is: before establishing the RAB service, pre-query the transmission layer bandwidth occupied by the RAB of each wireless bearer, judge whether the remaining bandwidth of the current Iub port can meet the transmission bandwidth resource request of the newly established or reconfigured call, according to the judgment result and according to The user access capability rejects users or triggers preemption in a timely manner, improving user satisfaction and realizing differentiated services.

[0075] That is, after the radio network controller receives the radio access bearer RAB assignment request message sent by the core network CN, before the radio link is reconfigured, it pre-determines whether the Iub bandwidth resource has sufficient transmission resources to bear the newly established service . The I...

Abstract

This invention discloses a bandwidth allocation method,system and wireless network controller in the wireless resource management of WCDMA honeycomb mobile communication system. When receiving the information of 'wireless access bearing assigned request' from core network, the wireless network controller inquires the current business bandwidths of users' request and Iub remainder, and then distributes the transmission bandwidth for the current users according to the result of inquiry.

Description

technical field [0001] The present invention relates to a bandwidth allocation method, system and wireless network controller, in particular to bandwidth in wireless resource management of a WCDMA (Wide-band Code Division Multiple Access; wideband code division multiple access system) cellular mobile communication system Assignment method, system and wireless network controller. Background technique [0002] One of the characteristics of the WCDMA cellular mobile communication system is that it can transmit multimedia services at multiple rates. Due to different application scenarios and service characteristics, different service types require different transmission rates, and their Qos (Quality of Service; Quality of Service) requirements are different. The service types of WCDMA transmission can be divided into conversational service, streaming service, interactive service and background service. Among them, interactive service and background service are characterized by s...
