Problems solved by technology

[0004] At present, when allocating / modifying RAB, HNB can only allocate / modify the resources of Iuh interface and Uu interface, but cannot complete the allocation / modification of Iu interface resources, and Iu interface resources are allocated / modified by HNB GW
This is likely to cause a mismatch between the Iuh interface resources allocated / modified by the HNB and the Iu interface resources
Moreover, the processing capabilities of HNB and HNB GW are different, and the Iuh interface resources allocated / modified by HNB may not be able to meet the processing capabilities of HNB GW

[0039] In the second embodiment of the present invention, the HNB GW first determines the initial QoS parameters according to the interface resource status of the device and the QoS parameters in the RAB assignment message sent by the CN, and then the HNB determines the final QoS that meets the requirements of the RAB bearer parameter. Such as figure 2 As shown, the second embodiment of the present invention corresponds to the following steps:

[0040] Step 201, the HNB GW determines the initial QoS parameter according to the interface resource status of the device and the QoS parameter in the RAB assignment message sent by the CN, and sends it to the HNB.

[0041] In order to realize the function of RAB establishment in the HNB scenario, the CN will select a QoS parameter for the RAB to be established according to the user's subscription information, the service itself, and the required QoS, and carry the QoS parameter in the RAB assignment message sent to the HNB GW . Th...

Abstract

The invention discloses a method for managing a radio access bearer (RAB), which comprises the following steps of: confirming a QoS parameter which meets the RAB requirement by interacting a first device with a second device according to a quality of service (QoS) parameter in a RAB assignment message sent by a core network (CN), and performing RAB distribution / modification through the first device and the second device according to the confirmed QoS parameter. The embodiment of the invention also provides a corresponding device and a corresponding system. Through the technical scheme of the invention, an interface resource for RAB distribution / modification is matched with an interface resource for HNB GW distribution / modification; and the interface resource for HNB distribution / modification can accord with the HNB GW handling ability.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a radio access bearer management method, device and system. Background technique [0002] At present, the 3G home base station (HNB) and home base station gateway (HNB GW) can jointly complete the function of the wireless area network, and the HNB and the HNB GW can access the core network through the standard Iu interface, and communicate with the user terminal through the Uu interface. The Iuh interface is used for communication between the HNB and the HNB GW. That is to say, the user plane data communicated between the user terminal and the core network needs to be sent or received through the three interfaces of Iu (Iu-PS or Iu-CS), Iuh and Uu. [0003] Therefore, the radio access bearer (Radio Access Bearer, RAB) established between the user terminal and the core network includes 3 segments: Iu, Iuh and Uu. When establishing RAB, it is necessary to alloc...
