The present invention relates to the field of communications, particularly to a method for reporting a lost radio bearer and the device information. From the point of view of development of the communication network, an IP packet subjected to the traditional circuit-switched networks to control bearer separate switching network and then all-IP multimedia networks such an evolutionary process.

In the all-IP network evolution to the need to consider end to end QoS Quality of Service, quality of service issues in order to provide our customers with the business especially real-time class of business. Because IP networks can provide a greater variety of services such as multimedia call, file downloads, web browsing, etc.

In general, GBR bearers for bandwidth sensitive real time traffic, such as VoIP Voice over Internet Protocol, Voice over Internet Protocol phone media streaming, video streaming and the like; the bandwidth instead of GBR bearers for non-real time service is not sensitive as well as some less demanding real-time business bandwidth, such as FTP file transfer protocol, file transfer protocol to download, HTTP hyperText transfer protocol, hypertext transfer protocol browser, email electronic mail, e-mailVoIP signaling flow Wait.

Currently, carriers can be well achieved by controlling the PCC architecture QoS flows, such as billing data carrier layer, in order to achieve specific details are upwardly shielded transport network layer to the service, the perceived downward transport network resource usage.

In one aspect PCRF Policy and Charging Rule Function, Policy and Charging Rules Function developed in accordance with the session negotiation service layer information indicating a corresponding policy control network using the bearer layer resources; on the other hand, when the use of the underlying bearer changes, for example, the user enters the coverage region not result in loss of radio bearers, the gateway failure or the like, may inform the business layer through the reporting mechanism, in order to make the appropriate changes to the business layer, provides the corresponding policy.

For the GBR Guaranteed bandwidth, guaranteed bandwidth bearing, because the transmission is basically a real-time service for this abnormal release radio bearer, even if time is very short, it is likely to lead to business interruption, so GBR bearer release are reasonable, but for non-GBR bearers, the adoption of non-GBR bearers release mechanisms, it will affect other defects IP address release bindings in the non-GBR bearers of iu interface signaling failure is not an option, as well as a default bearer release caused.

The embodiment provides a method for reporting a lost radio bearer and the information apparatus of the present invention, to solve the abnormality when the radio bearer release, radio bearer is achieved by releasing the non-GBR bearer information loss caused reporting mechanism: The above object of the present invention embodiments is achieved by the following technical solutions:.

The method and apparatus of the embodiments of the present invention, we achieved a reported lost radio bearer information, and avoids the problems caused because the release of non-GBR bearers. The drawings described herein are used to provide a ho into the understanding of the present iu interface signaling failure is not an option, constitute a part of this application, it does not limit the present invention.
