Embodiment
Core concept of the present invention is: in the WCDMA system, SRNC (Serving Radio NetworkController, service wireless network controller) utilize up-downgoing node synchronization message between itself and base station to obtain the time delay of IUB mouth, and can be further according to the average delay of this time delay or a plurality of time delays and/or realize the automatic configuration of UU mouth layer 2 parameter according to the shake that a plurality of time delays obtain.
Because what the WCDMA system used is the propagation delay time of TB (Transport Block, transmission block) piece, the time delay that detects with WCDMA system self with shake closing to reality demand more.
Below in conjunction with drawings and Examples the present invention is further described.
After the WCDMA sub-district was set up, SRNC can initiate as the node synchronizing process (this synchronizing process belongs to the 3gpp agreement) by IUB mouth user face.Present embodiment utilizes this existing node synchronizing process to calculate the time delay of IUB mouth automatically, and idiographic flow may further comprise the steps as shown in Figure 1:
Step S101, SRNC sends the descendant node synchronization message to base station NODE B, the data frame structure of this descendant node synchronization message as shown in Figure 2, the moment T1 of this descendant node synchronization message of transmission that when the base station sends this descendant node synchronization message, writes down comprising this SRNC;
In the present embodiment, be that the value of T1 is distributed three bytes in the Frame of this descendant node synchronization message, be expressed as T1, T1 (cont.) and T1 (cont.) in the drawings, wherein cont. is continue, it is a T1 value that the byte of expression and front links up.
Step S102, the base station is after receiving this descendant node synchronization message, and recorder is to the moment T2 of this descendant node synchronization message;
Step S103, the upstream node synchronization message is returned to SRNC in the base station, the data frame structure of this upstream node synchronization message as shown in Figure 3, send the moment T1 of descendant node synchronization message comprising SRNC to the base station, the base station receives the moment T3 that the upstream node synchronization message is returned in the moment T2 of this descendant node synchronization message and the base station that writes down the base station when SRNC returns the upstream node synchronization message;
In the present embodiment, be that the value of T1, T2, T3 is distributed three bytes respectively at the Frame of this upstream node synchronization message.
After step S104, SRNC received this upstream node synchronization message, record SRNC received the moment T4 of this upstream node synchronization message;
Step S105, SRNC calculate the time delay of IUB mouth according to the T4 of the T1, the T2 that carry in this upstream node synchronization message, T3 and SRNC record.
Because the moment maximum in SRNC and the base station is 40959.875ms, after reaching 40959.875ms, again since 0, therefore the situation of T4＜T1 and/or T3＜T2 may appear, in these cases, calculate the time delay of IUB mouth in conjunction with this moment maximum 40959.875ms.In the present embodiment, calculate the time delay of IUB mouth by following formula:
When T3＞T2 and T4＞T1,
IUB?delay＝(T2-T1+T4-T3)/2 (1)
When T3＞T2 and T4＜T1,
IUB?delay＝(T2-T1+(T4+40959.875)-T3)/2 (2)
When T3＜T2 and T4＞T1,
IUB?delay＝(T2-T1+T4-(T3+40959.875))/2 (3)
When T3＜T2 and T4＜T1,
IUB?delay＝(T2-T1+(T4+40959.875)-(T3+40959.875))/2
＝(T2-T1+T4-T3)/2
Promptly when T3＜T2 and T4＜T1, also adopt formula (1) to calculate the time delay of IUB mouth.
As seen, in the above-mentioned flow process, step S101 is the synchronizing process of the existing interface protocol of 3gpp to step S103, and this enforcement has utilized this synchronizing process, makes SRNC only need carry out simple operation and just can obtain time delay.
In an example of the present invention, the up-downgoing node synchronization message between SRNC and base station as shown in Figure 4, SRNC frame number among the figure and base station frame number are by constantly being converted to, every 10ms is a frame.As shown in the figure, comprise in the descendant node synchronization message that this SRNC sends the moment T1 of this descendant node synchronization message to the base station, T1 is 40941.250ms.The base station sends the upstream node synchronization message to SRNC and comprises that SRNC sends the moment T1 (40941.250ms) of descendant node synchronization message to base station NODE B, and moment T2 (1492.500ms), the base station that the base station receives this descendant node synchronization message sends the moment T3 (1505.000ms) of the corresponding upstream node synchronization message of this descendant node synchronization message.After SRNC receives this upstream node synchronization message, know that SRNC receives the moment T4 (312.000ms) of this upstream node synchronization message, because in this example, T3＞T2 and T4＜T1, so adopt formula (2) to calculate the time delay of IUB mouth:
IUB?delay＝(T2-T1+(T4+40959.875)-T3)/2
＝(1492.500-40941.250+(312.000+40959.875)-1505.000)/2
＝159.0625(ms)
Calculate the IUB mouth the time delay, SRNC can be according to automatic configuration UU mouth layer 2 parameter relevant with time delay of this time delay, this layoutprocedure may further comprise the steps as shown in Figure 5:
Step S501, SRNC determines its time delay grade according to the predefined time delay scope that the IUB mouth time delay value that calculates falls into;
Step S502, SRNC in pre-configured sign time delay grade and UU mouth layer 2 parameter relevant with time delay (as RLC (Radio Link Control, Radio Link control) parameter, OLPC (OutLoop PowerControl, exterior ring power control) parameter and L2 caching delay, set up chain-circuit time delay etc.) the mapping table of mapping relations in search the parameter value of relevant UU mouth layer 2 parameter of this time delay grade correspondence;
Step S503, SRNC is configured to the UU mouth automatically with the above-mentioned parameter value.
Equally, SRNC can calculate the time delay of a plurality of IUB mouths, and ask for the average delay of a plurality of IUB mouth time delays, to obtain more accurate IUB mouth time delay, then according to the time delay grade of this average delay correspondence, in the mapping table of the mapping relations of pre-configured sign time delay grade and UU mouth layer 2 parameter relevant, search the parameter value of corresponding relevant UU mouth layer 2 parameter of this time delay grade, and parameter value is configured to the UU mouth automatically with time delay.
In the present embodiment, SRNC can also calculate the time delay of a plurality of IUB mouths, and according to the shake of the time-delay calculation IUB mouth of these a plurality of IUB mouths, then according to this shake automatically configuration with shake relevant UU mouth layer 2 parameter.
SRNC can calculate the shake of IUB mouth by following formula:
jitter＝IUB?delay(max)-IUB?delay(min) (4)
Wherein, the maximum delay of Yanzhong during a plurality of IUB mouth of IUB delay (max) expression, the minimal time delay of Yanzhong during a plurality of IUB mouth of IUB delay (min) expression.
SRNC is after the shake that obtains the IUB mouth, can calculate parameter value TOAWS (the Time Of Arrival WindowStartpoint of the UU mouth layer 2 parameter time window relevant according to this shake with shake by following formula, the time of advent window starting point) and TOAWE (Time Of Arrival Window Endpoint, the time of advent window terminal point):
TOAWE＝jitter (5)
TOAWS=1.2 * jitter+ guard time (6)
In the present embodiment, this guard time is 15ms.
SRNC is after calculating the parameter value of time window, and the parameter value of configurator timing window is to the UU mouth automatically.
Infer easily, SRNC can only dispose UU mouth layer 2 parameter relevant with time delay according to time delay automatically, only the average delay according to a plurality of time delays disposes UU mouth layer 2 parameter relevant with time delay automatically, also can only dispose UU mouth layer 2 parameter relevant automatically with shake according to shake, perhaps not only according to time delay UU mouth layer 2 parameter that configuration is relevant with time delay automatically but also according to shake configuration UU mouth layer 2 parameter relevant automatically, not only disposed automatically and shook UU mouth layer 2 parameter of being correlated with according to average delay UU mouth layer 2 parameter that configuration is relevant with time delay automatically but also according to shake with shake.
