Problems solved by technology

When the user needs to adjust the bandwidth rate, the OTT server sends a bandwidth rate adjustment request. If the bandwidth rate parameter carried in the bandwidth rate adjustment request does not match the bandwidth rate parameter range that can be identified by the network side, the packet data network gateway (packet data network gateway, PGW) rejects the bandwidth rate adjustment request, returns a reject acceleration request message, and the dedicated bearer fails to be established, resulting in the failure of 4G QoS differentiated services and the failure to guarantee the success rate of the business

Abstract

The embodiment of the invention provides a bearer establishment method, a device and a system, relates to the field of communication, and is used for improving the success rate of establishing a proprietary bearer by a terminal. The method comprises the following steps: a gateway sends a second message to a PCC service management server; wherein the second message comprises a second bandwidth rate, and the second bandwidth rate is a bandwidth rate supported by the gateway; the PCC service management server receives a first message sent by the OTT server; wherein the first message comprises a first bandwidth rate, and the first bandwidth rate is a bandwidth rate requested by the OTT server for the terminal; matching the first bandwidth rate with the second bandwidth rate; wherein the secondbandwidth rate is a bandwidth rate supported by a gateway corresponding to the terminal; if the first bandwidth rate is not matched with the second bandwidth rate, adjusting the first bandwidth rateaccording to the second bandwidth rate to obtain a third bandwidth rate; wherein the third bandwidth rate is used for establishing a bearer of the terminal; and sending the third bandwidth rate to theAAC network element by the PCC service management server. The method is used for establishing a proprietary bearer for a terminal.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for establishing a bearer. Background technique [0002] With the explosive growth of data services, it is imperative to deepen the traffic management strategy and promote the transformation from a single traffic package to an intensive traffic classification product. The fourth generation (4th generation, 4G) mobile network is based on the policy and charging control (policy and charging control, PCC) system architecture, and the 4G service quality (quality of service, QoS) dynamic management mechanism provides a technical basis for differentiated services , 4G QoS implements functions such as policy control decision-making and charging control through the policy and charging rule function (PCRF), and cooperates with the 4G core network, transmission network and wireless network to realize the service level identification (QoS class indentifer , QCI...
