T10 represents that UE has received that radio bearer reshuffles (RADIO BEARRECONFIGURATION) message and reshuffle the time delay of finishing (RADIO BEARRECONFIGURATION COMPLETE) message to sending radio bearer.This procedural representation UE has finished the processing that radio bearer is reshuffled.
T7/t8/t9 reflected from the signaling link and finished to beginning to count biography, carries out the time delay index that dynamic channel is adjusted to network side according to the actual number condition that conveys feelings.UE can be known the WCDMA network system at end of signaling by the test to t7/t8/t9, passes the time delay index of adjusting to number.
System carries out RADIO BEAR RECONFIGURATION configuration to UE, finishes the resource adjustment of line number biography up and down.Carry the adjustment cell of the resource that is used for the line number biography in the RADIO BEAR RECONFIGURATION message respectively, and carry the adjustment cell that is used for following line number biography resource.RADIO BEAR RECONFIGURATION can only carry up cell, only goes up the adjustment that line number passes resource; Also can only carry descending cell, only descend line number to pass the adjustment of resource; Can also carry the cell of up-downgoing simultaneously, carry out the adjustment that the uplink and downlink number passes resource simultaneously.
Above-mentioned time delay index can also be generalized to general wireless communication system.Show the part reciprocal process of UE and network in the wireless communication system one as Fig. 2.Below mutual step is done some explanations.
1, carries out professional foundation between UE and the network.
2, finished professional foundation between UE and the network, message can be that UE informs network, also can be that network is informed UE.
3, network side issuing service measurement amount control messages is given UE, is used to notify UE to carry out the detection of actual volume.
4, UE according to the configuration information of service volume measurement and control configuration, judges whether the UE inner buffer is too much or very few according to the actual conditions of traffic carrying capacity, if the inner buffer data surpass and are lower than certain thresholding, reporting measurement reports is given network side.This measuring business volume can only be assessed up traffic carrying capacity in the UE side, and descending traffic carrying capacity is assessed at network side.
5, network side is received the measurement report of UE, carries out the preparation of internal resource, sends the message that service bandwidth is reshuffled to UE, requires to reshuffle bandwidth.
6, UE receives the service bandwidth reconfiguration message of network, begins to carry out the reconfiguration course of the service bandwidth of UE side, finishes after the reshuffling of service bandwidth, and sends service bandwidth and reshuffles and finish message to network.
The time delay index that relates in above-mentioned reciprocal process is as follows:
T7 represents to be accomplished to the time delay that UE receives the service volume measurement and control configuration of network from the foundation of UE reporting service.During this period, UE has finished the foundation of interior business, under the service volume measurement and control message of waiting for network.
T8 represents that UE is from receiving the service volume measurement and control configuration messages of network side, to the time delay of sending the measuring business volume report.During this period, the higher layer applications of UE will send data to network, and UE decides the trigger condition that when satisfies traffic carrying capacity by detecting inner buffer memory.
T9 represents that UE sends the measuring business volume report, to the time delay of receiving the service bandwidth reconfiguration message.During this period, the configuration of Internet resources is carried out in manage business measurement amount report of network side, and decision-making is reshuffled the service bandwidth of UE.
T10 represents that UE receives that the service bandwidth reconfiguration message reshuffles the time delay of finishing to sending service bandwidth.During this period, UE handles the service bandwidth reconfiguration message that network side sends, and adjusts the service bandwidth of UE side according to new configuration, adjust finish after, send service bandwidth and reshuffle and finish message to network.
By above-mentioned explanation, can know t7, t8, t9 described between network and the UE business set up finish after, during number passes, according to the adjustment process of actual volume to service bandwidth.The business amount monitor of UE side is just monitored at the buffer memory of upstream data.Descending business amount monitor is finished (for example RNC) at network side, the buffer memory of network internal monitoring downlink data, and whether decision-making sends the service bandwidth reconfiguration message to UE.When network sends the service bandwidth reconfiguration message, and when the sending measuring control messages is given UE to UE and network side, and UE when reporting measurement reports does not have restriction relation on the time delay to network side.Therefore the time delay definition of t7/t8/t9 description just from the time delay of signaling angle evaluating system, has been described the uplink time delay restriction relation, and the upper and lower line number that is not suitable for evaluating system passes the time delay index.And in fact upper and lower line number biography time delay also has great importance to the network optimization.
