2, the determination method for the signal blind zone that determination method and above-described embodiment 1 of signal blind zone provided in this embodiment provide is similar
It seemingly, equally include 1~S4 of step S.It is described in detail since step S1~S4 there has been in embodiment 1, it is no longer superfluous herein
It states.
The difference of the application Yu above-described embodiment 1 are only described below.Specifically, referring to Fig. 2, in this embodiment,
The step S2 can be realized with S21~S23 as follows.
S21 obtains all Missing Call Notification data of the different user terminals.
Wherein, Missing Call Notification may betide that user terminal is in off-mode or user terminal is in signal
The case where shielding area (region for referring to the shielded signals such as the lesser elevator of permission), therefore, the different users, are whole
All Missing Call Notification data at end had both included that user terminal is in the Missing Call Notification occurred when off-mode
Data, also include that user terminal is in the data of the Missing Call Notification occurred when above-mentioned signal shielding region.
S22 judges whether each Missing Call Notification in all Missing Call Notification data is user terminal
The Missing Call Notification occurred when in off-mode.
Specifically, step S22 includes but is not limited to be realized by the following two kinds mode:
First way: judging the shutdown signaling data that whether there is user terminal in the core network signalling data, and
Whether the shutdown signaling data has any other letter between corresponding shutdown moment and the generation moment of the Missing Call Notification
Enable data；If there is the shutdown signaling data of user terminal, and the shutdown signaling data corresponding shutdown moment with
There is no any other signaling data between the generation moment of the Missing Call Notification, it is determined that the Missing Call Notification is that user is whole
The Missing Call Notification occurred when end is in off-mode；
If be appreciated that between shutdown signaling data corresponding shutdown moment and the generation moment of the Missing Call Notification
There is no any other signaling data, then can determine user terminal between shutdown moment and the generation moment of the Missing Call Notification
It is constantly in off-mode, hence, it can be determined that the secondary Missing Call Notification is that user terminal is in and occurs when off-mode
Missing Call Notification.
The second way: judging the booting signaling data that whether there is user terminal in the core network signalling data, and
Whether there is any other letter between available machine time corresponding with the booting signaling data at the generation moment of the Missing Call Notification
Enable data；If there is the booting signaling data of user terminal, and the generation moment of the Missing Call Notification opens with described
Machine signaling data does not have any other signaling data between the corresponding booting moment, it is determined that the Missing Call Notification is that user is whole
The Missing Call Notification occurred when end is in off-mode.
If being appreciated that the booting moment corresponding with the booting signaling data at generation moment of the Missing Call Notification
Between there is no any other signaling data, then can determine user between generation moment of the Missing Call Notification and booting moment
Terminal is constantly in off-mode, hence, it can be determined that the secondary Missing Call Notification is that user terminal is sent out when being in off-mode
Raw Missing Call Notification.
S23, if the Missing Call Notification is that user terminal is in the Missing Call Notification occurred when off-mode,
Delete the related data about the Missing Call Notification.
Due to the Missing Call Notification occurred when user terminal is in off-mode, can not reaction signal blind area position
Information, therefore, in embodiments of the present invention, the generation when determining that a Missing Call Notification is in off-mode for user terminal
Missing Call Notification, then the related data of the Missing Call Notification is deleted from all Missing Call Notification data, thus
It is deleted from all Missing Call Notification data to the otiose data in signal blind zone are determined, to reduce Missing Call Notification
Data volume in data, and then convenient for being quickly obtained signal blind zone.

When simplifying data otiose for determining signal blind zone in all Missing Call Notification data, also into one after step S23
Step includes the following steps S24 and step S25.Specifically,
S24, if the Missing Call Notification is that user terminal is in the Missing Call Notification occurred when non-off-mode,
It then inquires in the core network signalling data and exists at the generation moment of the Missing Call Notification with the presence or absence of other user terminals
Signaling data when same position is in active user's terminal.
S25, if there is other user terminals and active user's terminal when being in same position with active user's terminal
Signaling data, then delete the related data about the Missing Call Notification.
It is appreciated that being in same position with active user's terminal if there is other user terminals and active user's terminal
Signaling data when setting can then determine that the position not belongs to signal blind zone, but not due to the signal of user terminal itself
Well or Missing Call Notification data are resulted in above-mentioned signal shielding region, therefore, deleted about the missed call notification industry
The related data of business.
Preferably, S25, if there is other a large amount of user terminals and active user's terminal with active user's terminal at
Signaling data when same position then deletes the related data about the Missing Call Notification, more can determine this in this way
Position not belongs to signal blind zone, but leads due to the poor signal of user terminal itself or in above-mentioned signal shielding region
Missing Call Notification data are caused.
Therefore, the present embodiment compared with Example 2, due to when user terminal is in above-mentioned signal shielding region or
When user terminal own signal problem, Missing Call Notification can equally occur, therefore, the embodiment of the present invention is in all missed call notifications
Other than the data of the Missing Call Notification occurred when user terminal to be deleted is in off-mode in business datum, also want
It deletes when user terminal is in above-mentioned signal shielding region and self problem leads to the data of the Missing Call Notification occurred, thus
It can further delete to the otiose data in signal blind zone are determined, be further reduced from all Missing Call Notification data
Data volume in Missing Call Notification data is further convenient for being quickly obtained signal blind zone.
