Abstract
The invention provides a method for reporting a multi-cell joint detection signal. According to the method, a special transmission channel is configured for the multi-cell joint detection signal, so that transmission delays of other signals caused by transmitting the multi-cell joint detection signal are reduced, and wastes of bandwidth resources caused by configuring larger bandwidth can also be avoided.
Description
Technical field
The present invention relates to the information transmission technology in the GSM, particularly relate to the report method that a kind of multi-plot joint detects signaling.
Background technology
In the present 3GPP agreement (3GPP TS 23.002); Wireless network layer comprises NCP, CCP, ALCAP 3 logic of class passages on the Iub interface signaling plane; Be specially: port (NodeB Control Port, NCP) link, some connection control ports (CommunicationControl Port, CCP) link and an Access Link Control Application Part (ALCAP) links are supported in a NodeB control; Wherein, The NCP link is used for the Signalling exchange of public procedure, and the CCP link is used for the Signalling exchange of dedicated process, and ALCAP is used for controlling foundation and the deletion of AAL2PATH.
The distinctive multi-plot joint detection algorithm (MCJD) that is used for reducing interference of TD-SCDMA system; Need NodeB to report " information of adjacent cells upgrades request " (NEIGHBORCELL INFORMATION UPDATE REQUEST) signaling through the Iub port to RNC, this signaling is transmitted in the NCP link.Because comprised the data message of each carrier wave of adjacent area in this signaling, data volume is very big, can arrive 3KB, even bigger, therefore, the bandwidth resources that can in a very long time, monopolize NCP, other signalings all must be waited in line during this period.And have pair propagation delay time to require very high public control procedure signaling in the NCP link, and set up request (RL_SET_REQ) like wireless network, its propagation delay time requires to be generally 10ms, might exert an influence to the call setup success rate if surpassed 50ms.
Provided under the different N CP band width configuration stand-by period of other signalings in the NCP passage in the table one, from table, can find out the increase along with the NCP band width configuration, the stand-by period of other signalings will reduce.Therefore,, can adopt the mode of the band width configuration that increases the NCP passage, reduce the holding time of MCJD signaling the NCP passage to the problems referred to above.In practical application, the MCJD signaling is no more than 24kbps at the average discharge of NCP, for " the single packet congestion " that reduce it influence to other signaling propagation delay times, need dispose the bandwidth of 500k even 1M for it.
It is thus clear that through increasing the band width configuration of NCP passage, though can reduce the propagation delay time of other signalings, this will cause under the not high situation of NCP average discharge and take the massive band width resource, thereby cause inefficiency, the bigger waste of transmission bandwidth.
Table 1
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of multi-plot joint to detect the report method of signaling, and this method can be avoided the waste of transmission bandwidth in the propagation delay time that reduces other signalings.
In order to achieve the above object, the technical scheme that the present invention proposes is: a kind of multi-plot joint detects the report method of signaling, and this method may further comprise the steps:
A, when the sub-district starts the multi-plot joint measuring ability; Utilize current Iub interface resource; For said cell configuration is used to transmit the designated lane that multi-plot joint detects signaling, wherein, the bandwidth of said designated lane satisfies the minimum transmission rate requirements that multi-plot joint detects signaling;
B, when the base station confirm to need is sent multi-plot joint and is detected signaling, only utilize said designated lane to transmit said multi-plot joint and detect signaling.
In sum; The multi-plot joint that the present invention proposes detects the report method of signaling; For detecting signaling configure dedicated passage, multi-plot joint transmits; Like this, both can effectively reduce the propagation delay time of other signalings that cause owing to transmission multi-plot joint detection signaling, can effectively avoid again because the waste of the bandwidth resources that the big bandwidth of configuration is caused.
Description of drawings
Fig. 1 is the schematic flow sheet of the embodiment of the invention one.
Embodiment
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing and specific embodiment that the present invention is done to describe in detail further below.
Core concept of the present invention is: the passage for multi-plot joint detection signaling configure dedicated, reduce its influence to other signaling propagation delay times.
Fig. 1 is the schematic flow sheet of the embodiment of the invention one.As shown in Figure 1, this embodiment mainly may further comprise the steps:
In this step, when starting the sub-district of multi-plot joint measuring ability, the system management attendant will utilize current Iub interface resource pool to detect the transmission channel of signaling configure dedicated for multi-plot joint network side (being specially RNC and base station).Said multi-plot joint detects signaling and comprises that mainly information of adjacent cells upgrades demand signalling.
Here, detect the minimum transmission rate requirements of signaling according to multi-plot joint and come the bandwidth of said designated lane is limited, like this, both can satisfy the minimum transmission rate requirements that multi-plot joint detects signaling, can reduce configuration greatly again bandwidth resources.
Usually in practical application; The minimum requirements that multi-plot joint detects the transmission time of signaling is 1 second, and correspondingly, the minimum transmission rate requirements that multi-plot joint detects signaling is 24kbps; Therefore; Here, need be with the band width configuration of said passage only more than or equal to 24kbps, can satisfy the transmission needs that multi-plot joint detects signaling.Even use 4 times 24kbps bandwidth, in 125ms, accomplish the transmission of this signaling, the bandwidth newly-increased for MCJD also is no more than 100kbps.So, the big packet that just need not consider MCJD in the planning of NCP passage only need generally just can satisfy the demands about 200kbps according to the intensity computation bandwidth needs of other signaling packets among the NCP to other signaling propagation delay time influences.Obviously, can improve efficiency of transmission like this, significantly reduce bandwidth demand.
Here; Owing to be to utilize the passage that is specifically designed to transmission multi-plot joint detection signaling to transmit the neighboring BS information update inquiry information of larger data amount; Promptly this message has only taken the part resource in the NCP link circuit resource; Other resources in the NCP link circuit resource then can be used for transmitting other public procedure signalings; Therefore, can not exist owing to the transmission multi-plot joint detects signaling to cause not having idle NCP link circuit resource to transmit the situation of other public procedure signalings, thereby effectively reduce the propagation delay time of other public procedure signalings.
In order further to verify technique effect of the present invention, the present invention has carried out corresponding experiment.At first; Test not using under MCJD designated lane, the situation of NCP configured bandwidth as 500kbps; Test through is after a while found: in the call set up signaling process of NCP transmission, the duration from RL SET REQ to RL SET RESPONSE surpasses 200ms sometimes.Then, at the special-purpose MCJD passage that uses 100kbps, test under the situation of the bandwidth of NCP configuration 200kbps, the duration from RL SET REQ to RL SET RESPONSE is all in 50ms.It is thus clear that the present invention under the situation that obtains less propagation delay time, can effectively reduce the band width configuration of NCP.
In sum, more than being merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
