Description

The delet method of common signal channel in the Iub mouth NBAP signaling

Technical field

The present invention relates to communication technique field, particularly relate to the delet method of common signal channel under the NBAP signaling protocol.

Background technology

The logical resource of NodeB (base station) is to be controlled by RNC (Radio Network Controller, radio network controller), and RNC sends the logical resource that configuration messages is managed NodeB by the Iub mouth to NodeB.The common signal channel of NodeB is the part of logical resource, controlled by RNC, by the foundation and the release of RNC decision common signal channel.Therefore the operating process of common signal channel being had a clear perfect description is the key of guaranteeing logical resource consistency and integrality between RNC and the NodeB.

Public physic channel PRACH (the Physical RandomAccess Channel that RNC sends to NodeB by the Iub mouth, physical channel) sets up message, common signal channel PRACH sets up and comprises following information in the message: a RACH (Random Access Channel, transmission channel) Common transport channel information, with this RACH channel one or more PRACH channel information and a FPACH channel information of mapping relations are arranged.ID (Identification) number of the usefulness channel is come in unique sub-district of sign in message public physic channel or Common transport channel.The RACH channel is a uplink transport channel, be used to carry control information from travelling carriage, the PRACH channel is a uplink physical channel, it is the final carrying of data message, article one, the RACH channel can be mapped on one or more up PRACH channels, that is to say that RACH channel and PRACH channel are the relations (referring to Fig. 1) of one-to-many.In this case, can determine the capacity of RACH flexibly according to network operator's needs.

The structure of the Common transport channel deletion message of Iub mouth NBAP (Node B Application Part) signaling protocol can only identify a physical channel ID, deletion for common signal channel PRACH, can provide the ID of a PRACH channel in Common transport channel message, PRACH channel delete procedure is to describe like this in Iub mouth NBAP signaling protocol:

If the public physic channel in Common transport channel deletion request message sign is the PRACH channel, NodeB will delete the Common transport channel RACH that the PRACH channel of indicating in the message and this PRACH channel are supported.

Owing to can only identify a physical channel in the structure of a Common transport channel deletion message, according to the deletion mode in the agreement, only delete the Common transport channel RACH that this PRACH channel and this PRACH channel are supported, will exist the PRACH channel that does not have RACH channel correspondence (referring to Fig. 2 so among the NodeB, the PRACH channel 212 that identifies in the structure of RACH channel 201 that frame of broken lines is represented and deletion message thereof is deleted, but, RACH channel 201 was to be mapped to a plurality of PRACH channels 211,212 originally ..., also have not deleted PRACH channel 211).That is to say that this channel deletion mode can cause the imperfect of NodeB common channel resources, causes the leakage of resource.

Embodiment

The situation that the present invention is directed to this resource leakage has proposed solution, its core content is exactly not only to delete the Common transport channel RACH that the PRACH channel of indicating in channel deletion message and this PRACH channel are supported, and have all PRACH channels of mapping relations also to delete with RACH, can guarantee the integrality of NodeB common channel resources when carrying out the common signal channel deletion like this.

The present invention is directed to this solution and provide two kinds of execution modes:

Execution mode one

RNC at first can set up request message to the common signal channel PRACH that NodeB sends by the Iub mouth, can comprise following information in the message, the ID of the ID of a RACH channel, one or more PRACH channel.

Because following description is arranged in Iub mouth NBAP signaling protocol:

If any channel that common signal channel is set up in the request message exists, NodeB will reply and set up failure so.

Can think that common signal channel PRACH sets up the RACH channel that identifies in the request message and its mapping one or many PRACH channels and sets up in the message at common signal channel and describe fully, can not set up and comprise same RACH channel or PRACH channel information in the message at the common signal channel PRACH that other are arranged.

NodeB can set up the information of PRACH channel and RACH channel in the message according to common signal channel like this, sets up the bi-directional association (referring to Fig. 3) between RACH channel 301 and a plurality of PRACH channel 311,312,313.This bi-directional association can guarantee the ID by any PRACH channel, can find the RACH channel 301 of this PRACH channel correspondence; By the ID of RACH channel 301, can find all PRACH channels of these RACH channel 301 correspondences.

Pass through the Iub mouth when NodeB sends common signal channel PRACH deletion request message at RNC, the ID that has only a PRACH channel (for example the PRACH channel 311) in the message, according to this ID value, search the RACH channel 301 of PRACH channel 311 associations, related information according to RACH channel 301 finds all PRACH channels 312,313 that mapping relations are arranged with this RACH channel 301 again, has all PRACH channels 311,312,313 of mapping relations to delete this RACH channel 301 with this RACH channel.

Execution mode two

NodeB sets up the information of PRACH channel and RACH channel in the message according to common signal channel, sets up unidirectional related (referring to Fig. 4) between RACH channel 401 and the PRACH channel 411,412,413.This unidirectional association can guarantee the ID by RACH channel 401, can find all PRACH channels 411,412,413 of this RACH channel correspondence.

Revise the message content of common signal channel PRACH deletion request message in the existing protocol, the ID of the RACH channel 401 that the direct transmission of RNC will be deleted, find all PRACH channels 411,412,413 that mapping relations are arranged with this RACH channel 401 according to this ID value, have all PRACH channels 411,412,413 of mapping relations to delete this RACH channel 401 with this RACH channel.

The comparison of two kinds of execution modes

1, execution mode one does not change in the agreement message content of existing deletion request message, but by set up the mode of bi-directional association at NodeB, reach deletion RACH channel and with the purpose of related all the PRACH channels of this RACH channel.

2, execution mode two has changed the message content of existing deletion request message in the agreement, but only need set up the unidirectional incidence relation of RACH channel and PRACH channel in the NodeB side, just can arrive deletion RACH channel and with the purpose of related all the PRACH channels of this RACH channel.

Below describe the concrete operating procedure of execution mode in detail

Referring to Fig. 5, be that NodeB receives the treatment step after Common transport channel that RNC sends is set up message, comprising:

Step 501:NodeB is receiving that Common transport channel sets up message;

Step 502: judge whether this message is that the PRACH channel is set up, and is then to enter step 503, otherwise progressive rapid 504;

Step 503: extract RACH channel and PRACH channel information, set up the incidence relation of the ID of the ID of RACH and PRACH.Adopt execution mode one will set up two-way association, adopt execution mode two to set up unidirectional association and just can;

Step 504: finish.

Referring to accompanying drawing 6, be the treatment step after NodeB receives the Common transport channel deletion message that RNC sends, comprising:

Step 601: receive Common transport channel deletion message;

Step 602: judging whether the physical channel type in the message is the PRACH channel, is then to enter step 603, otherwise progressive rapid 604;

Step 603: obtain the ID value in the message, if execution mode one: then be the ID of PRACH channel,, find corresponding RACH channel then according to the bi-directional association of in Fig. 1, setting up, find all PRACH channels of this channel correspondence again according to the association of RACH channel, in the lump deletion; If execution mode two: then be the ID of RACH channel, then according to the unidirectional association of in Fig. 4, setting up, find all PRACH channels of this RACH channel correspondence, in the lump deletion;

Step 604: finish.

As from the foregoing, the inventive method is not only deleted the Common transport channel RACH that the PRACH channel of indicating and this PRACH channel are supported in channel deletion message, and there are all PRACH channels of mapping relations also to delete with RACH, so just guarantee the integrality of NodeB common channel resources when carrying out the common signal channel deletion, prevented resource leakage.
