Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide a method for deleting common channel in Iub mouth NBAP signaling, solve existing agreement and can only delete a physical channel that is identified by message, have produced the corresponding PRACH channel that does not have RACH channel, thereby Technical issues caused by resource leaks

Embodiment approach 1

[0028] The RNC will first send a public channel PRACH establishment request message to the NodeB through the Iub port, and the message will include the following information, the ID of one RACH channel, and the IDs of one or more PRACH channels.

[0029] Due to the following description in the Iub port NBAP signaling protocol:

[0030] If any channel in the common channel establishment request message already exists, NodeB will reply that the establishment fails.

[0031] It can be considered that the RACH channel identified in the common channel PRACH establishment request message and one or more PRACH channels mapped to it have been fully described in the common channel establishment message, and the same RACH channel will not be included in other common channel PRACH establishment messages Or PRACH channel information.

[0032] In this way, the Node B can establish a bidirectional association between the RACH channel 301 and a plurality of PRACH channels 311, 312, and 313 ...

Embodiment approach 2

[0035] The Node B establishes a one-way association between the RACH channel 401 and the PRACH channels 411, 412, and 413 according to the information of the PRACH channel and the RACH channel in the common channel establishment message (see Figure 4). This one-way association can ensure that all PRACH channels 411 , 412 , and 413 corresponding to the RACH channel can be found through the ID of the RACH channel 401 .

[0036] Modify the message content of the common channel PRACH deletion request message in the existing protocol, RNC directly sends the ID of the RACH channel 401 to be deleted, and finds all PRACH channels 411, 412, 413 that have a mapping relationship with this RACH channel 401 according to the ID value , delete the RACH channel 401 and all the PRACH channels 411 , 412 , and 413 that have a mapping relationship with the RACH channel.

Abstract

This invention discloses a kind of Iub interface NBAP signal public signal deletion method. It comprises: for the public transmission channel and public physical channel that have mapping relation, it builds ID association between various channel IDs according to the said mapping relation. For the channel that needs to be deleted, in the said ID association it finds all channels that associate with that channel ID directly or indirectly. It considers all the found channels as related channels, and deletes them with the channel that needs to be deleted. This invention ensures integration of public channel resource of base station during deletion of public channel.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for deleting a common channel under the NBAP signaling protocol. Background technique [0002] The logical resources of the NodeB (base station) are controlled by the RNC (Radio Network Controller, radio network controller), and the RNC sends configuration messages to the Node B through the Iub port to manage the logical resources of the NodeB. The common channel of NodeB is a part of logical resources, which is also controlled by RNC, and the RNC decides the establishment and release of the common channel. Therefore, it is the key to ensure the consistency and integrity of logical resources between RNC and NodeB to have a clear and complete description of the operation process of the common channel. [0003] The public physical channel PRACH (Physical Random Access Channel, physical channel) that RNC sends to NodeB through the Iub port establishes a message, and ...
