Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
The WCDMA network designs two scheduling periods for CBS: DRX Level1 and DRX Level2, the DRX period of Level1 is configured in the system message by the network, and the invention is called CBS period. In actual network configuration, the CBS message is not sent in each CBS cycle, but several CBS data blocks are continuously sent in each cycle at intervals of a larger cycle to form a CBS scheduling message or CBS data message, where the larger cycle is Level2, and in the scheduling cycle of Level2, the UE continuously receives the CBS data blocks according to the DRX cycle of Level1, i.e., the CBS cycle. The invention refers to a scheduling period of Level2 as a period Msg Cycle for sending CBS messages by a network, and refers to that one CBS message needs to be continuously received with the length Msg Len.
The invention provides a pilot frequency or inter-system measurement method, as shown in fig. 1, the method comprises:
s11, acquiring an initial system frame number of the current CBS message according to the previous CBS message containing the scheduling information;
the UE can only receive messages according to CBS cycles when it just enters idle state, and the starting position and length of DRX Level2 are carried in scheduling information for notifying the starting position of the next CBS packet and continuously receiving the length of several CBS cycles. If the UE receives the scheduling information, the initial system frame number of the next CBS message can be calculated, and the scheduling period of DRX Level2 is entered.
S12, judging whether the difference value of the sequence numbers of the two latest received data packets is equal to the number of CBS data blocks received between the two data packets;
optionally, calculating a difference between a system frame number of a CBS data block received first in a current data packet and a system frame number of a CBS data block received first in a previous data packet, and dividing the difference by a CBS period to obtain the number of CBS data blocks between the two data packets, where the CBS period is a period configured by a network for sending a CBS message block;
and judging whether the difference value of the sequence numbers of the two data packets is equal to the number of CBS data blocks received between the two data packets according to the calculation result.
S13, learning a sending mode of the CBS message according to the judgment result and the initial system frame number to obtain a Cycle Msg Cycle for sending the CBS message by the network and a length Msg Len for continuously receiving the CBS message;
optionally, when the judgment results are equal, indicating that two newly received data packets belong to the same CBS message, adding the difference value of the two sequence numbers into the Msg Len; when the judgment results are not equal, the two latest received data packets do not belong to the same CBS message, and the Msg Cycle is equal to the difference value between the system frame number of the CBS data block received firstly in the current data packet and the initial system frame number;
and repeating the above operations, and after N CBS messages are continuously learned or a learning time limit is reached, if the calculated proportion of the same Msg cycles exceeds a specified percentage, determining the Msg cycles as the final Msg cycles, and determining the value of the Msg Len as the maximum value of the obtained Msg Len, wherein N is more than 0 and N is an integer.
And S14, when the CBS message cannot be received, determining the initial position of the next CBS message according to the learning result, and receiving the inter-frequency or inter-system measurement message after continuously receiving the CBS message and before starting to receive the next CBS message.
When the CBS message can not be received, the initial position of the next CBS message is determined according to the learning result, and after one CBS message is continuously received and before the next CBS message is started to be received, the CBS data blocks have no content and do not need to be received.
The different-frequency or different-system measuring method provided by the invention is specifically explained by using specific examples.
As shown in fig. 2, the scheduling pattern of CBS is: the message blocks CBS0 and CBS1 constitute a CBS message, and if the message is a scheduling message, the network will tell the UE that the next message has no content at CBS4 and CBS5, and CBS2 and CBS3, and may not receive it. However, if CBS1 is not received, it cannot compose a scheduling message, and the UE cannot know where the next CBS message is. Or the network does not send scheduling messages at all, the UE has to receive CBS2 and CBS3 even if the two CBS data blocks are without content and may not be received at all.
The scheduling mode of the original pilot frequency or pilot system measurement is as follows: at the same frequency (INTRA in fig. 2), paging (PAING, PI) messages are normally received, without affecting CBS message blocks; messages for INTER-frequency measurements (INTER in fig. 2) or INTER-System measurements (e.g. GSM (Global System for Mobile Communications, GSM) in fig. 2) may collide with the reception of CBS message blocks.
Therefore, the present invention provides a method for learning CBS message sending mode, under the condition that CBS message can not be received, msg Len and Msg Cycle are calculated by learning CBS message sending mode, and the starting position of the next CBS message is predicted, so that inter-frequency or inter-system measurement is arranged at the place where no content is required to be received, such as the new scheduling mode of inter-frequency or inter-system measurement in fig. 2.
The following describes an algorithm for learning the CBS messaging mode in detail.
Firstly, acquiring a starting SFN (System Frame Number) of a current CBS message according to a previously received CBS scheduling message;
judging whether the SN (Serial Number) difference of the two latest packet data is the same as the CBS data block received between the two packet data, if so, determining that the two packet data are the same as a CBS message and needing to be calculated into the Msg Len. If the SN difference of the two latest packet data is less than the number of the CBS data blocks received between the two packet data, the packet data is considered to be a new CBS message, and the SFN difference between the new CBS message and the current CBS message, namely the Msg Cycle, can be calculated;
and repeating the learning steps until reaching the judgment condition of learning end.
Judgment of end of learning algorithm:
if more than 70% of the Msg cycles in 10 consecutive CBS messages are the same, the Msg cycles are considered reliable; msg Len takes the maximum value.
As shown in fig. 3, a flow chart of an algorithm for learning CBS messaging patterns is shown.
As defined below:
SFN0: the starting system frame number of the current CBS message;
SFN1: the system frame number of the CBS data block received firstly in the last data packet;
SFN2: the system frame number of the CBS data block received firstly in the current data packet;
SN1: the sequence number in the header of the previous data packet;
SN2: the sequence number in the header of the current packet.
The steps of the learning algorithm are as follows:
s100: the CBS send pattern learning process begins;
s101: initializing SFN0, SFN1, SFN2, SN1 and SN2;
s102: judging whether CRC (Cyclic Redundancy Check) passes or not; when the pass is passed, go to S103; when the data is not passed, turning to S109;
s103: judging whether the (SFN 2-SFN 1)/CBS period is equal to (SN 2-SN 1), and turning to S104 when the judgment is equal; when the judgment result is not equal, turning to S106;
S104：Msg Len＝Msg Len+(SN2–SN1)；
s105: let SFN1= SFN2; SN1= SN2;
S106：Msg Cycle＝SFN2–SFN0；
s107: saving the Msg Cycle and the Msg Len;
s108: let SFN0= SFN2; SFN1= SFN2; SN1= SN2; msg Len =0;
s109: judging whether the learning time reaches a threshold; when the threshold is reached, turning to S110; otherwise, turning to S102;
s110: the CBS transmission pattern learning process ends.
