Message details
RAN2 agrees with the information (such as packet reaches the CDF communications data field of interval time, the details for RAN3) about business model to be supplied to Radio Access Network from core network.
Here, the statistical information of only last connection is not fine, because business model may be very different between two continuous print connect.But in the long cycle, it will represent stable state, such as, data frequently or infrequently.Therefore the present invention advises that these statistics are in the long duration, such as, calculate in several hours or several days.The duration of this length is one-period, and within this cycle, in fact subscriber equipment represents the subscriber equipment activity level of expection on the whole, such as high activity, activity and low activity.
Propose 1: in order to improve reliability, the statistics of business model not only should be calculated by calculating in the long duration in upper connection once.
The CDF communications data field of packet interarrival time may comprise many forms, such as, and mean value, maximum, standard deviation square value or practical communication data field curve.But in order to reduce core network signaling traffic load, these parameters are expected to be and are formed simply as much as possible.
In order to the CDF communications data field of data of description Inter-arrival Time time, we have proposed simple parameter below, it is considered to important:
Average, maximum with the minimum connect hours
This statistics is considered all access phases experienced by subscriber equipment during long continuous time period and is calculated.
Average, maximum with minimum free time
This is the respective value of current connect hours, and this statistics is considered time between any two access phases experienced by subscriber equipment during long continuous time period and calculated.
Average, minimum with maximum interarrival time
To be defined as in superincumbent total connect hours all reaches average (respective minimum, maximum) value of interval time, such as consider long duration when all stages of subscriber equipment in connection mode.
These parameters that base station receives can determine the state of transfer of data.Therefore, the parameter of current connection, such as discontinuous reception modes and dormant state timer can be provided as previous observation.
