The present invention will be further described in detail below with reference to the accompanying drawings. It is apparent that the described embodiments are only a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

In the embodiment of the present invention, the power failure of the user data card of the terminal may be caused by the user unplugging the user data card, or may be caused by the damage of the user data card. Therefore, for the network device, to optimize the network. When the call drop rate statistics are performed for the purpose, the call drop caused by the power consumption of the user data card of the terminal does not need to be counted in the call rate statistics, thereby improving the accuracy of the dropped call rate.

Referring to Figure 1, there is shown a flow chart of a communication method in accordance with an embodiment of the present invention. This embodiment can be applied to a user terminal, and specifically includes the following steps.

Step 101: If the terminal is dropped, and the reason for the dropped call is that the user data card of the terminal is powered off, the terminal saves the first flag, where the first flag is used to indicate that the terminal is in the user The data card is powered off and dropped.

For example, if the terminal is dropped, and the reason for the dropped call is that the user data card of the terminal is powered off, the first flag saved by the terminal is given a first value, and the first value is used to indicate the terminal. Dropped (or called abnormal release) due to power loss of the user data card.

Step 102: After the terminal is powered on, send the first identifier to the network device.

It can be understood that the terminal sends the first tag to the network device to enable the network device to learn that the terminal is dropped due to power failure of the user data card.

The method shown in FIG. 1 is used, because the terminal can send the information that the call loss is caused to the user data card to the network device, so that the network device (such as the base station) can accurately know which dropped calls are caused by the power failure of the user data card. Can distinguish between dropped calls caused by power failure of the data card.

Optionally, in addition to the step shown in FIG. 1, the embodiment further includes: the terminal sending, by the terminal, a global cell identifier (CGI, Cell Global Index) and a time-out timestamp of the first cell to the network device, where The first cell is a cell in which the terminal is located when the call is dropped, and the dropped timestamp is time information when the terminal drops the call.

Optionally, the CGI and the dropped call timestamp of the first cell are recorded by the terminal when the call is dropped. For example, when the terminal drops the call, the CGI and the dropped call time of the first cell may be recorded while the first mark is recorded.

Optionally, the first identifier may carry a RRC (Radio Resource Control) connection establishment completion (RRCConnectionSetupComplete) message or an information response message sent by the terminal to the network device, or may It is carried in other new messages that are different from the existing protocol messages.

Optionally, the RRC connection setup complete message or the information response message or the new message may further carry the CGI of the first cell and the dropped call timestamp. Optionally, the embodiment further includes: when the network device counts the dropped call rate of the terminal, first removing the call drop caused by the power failure of the user data card from the dropped call statistics, and then removing the user data by using the user data card. The call drop statistics result after the call is dropped, and the dropped call rate is calculated, thereby obtaining an accurate call drop rate and a dropped call result, thereby making the network device's dropped call statistics result inaccurate. In addition, the network device can effectively guide network optimization and network positioning based on the accurate call drop rate.

The following is an example of adding a field in the RRCConnectionSetupComplete message and the information response message to carry the above information.

For example, the first mark above may be represented by a newly added data card flag (DropDatacardFlg). The DropDatacardFlg can indicate that the data card is being pulled, that is, the data card is powered off. Further, the DropDatacardFlg may be an enumerated type. For example, when the DropDatacardFlg value is true (true), the data card is pulled.

As another example, the dropped timestamp can be represented by a newly added absolute time stamp (absoluteTimeStamp). The absoluteTimeStamp is used to indicate the absolute time when the terminal drops the call, and can occupy 48 bits. The absoluteTimeStamp format can be year-month-day (YY-MM-DD) hour-minute-second (HH:MM:SS), using binary encoding.

For another example, the CGI of the first cell may be represented by a newly added data card cell identifier (DropDatacardCGI). The DropDatacardCGI is the identity CGI of the cell in which the terminal is located when the data card is powered off. Optionally, the DropDatacardCGI may adopt a cell global identifier structure, CellGloballdEUTRA, and the structure of the CellGloballdEUTRA includes the following elements: CellGloballdEUTRA. The CellGloballdEUTRA contains the Evolved Cell Global Identifier (ECGI) and the globally unique identifier in E-UTRA. Among them, E-UTRA represents Evolved UMTS Terrestrial Radio Access, and UMTS is a Universal Mobile Telecommunications System. Further, the above CellGloballdEUTRA further includes a public land mobile network identifier (plmn Identity) and a cell identity (cellldentity).

The following is an example of carrying the above information by using a new message, and the new message is a DropDatacardReport message reported by the data card.

For example, the DropDatacardReport message is used by the terminal to report that the data card is pulled to the network side (such as E-UTRAN), and the Signalling radio bearer used by the terminal may be SRB1. The RLC (Service Link Access Point) can be an acknowledged mode (AM), and the logical channel used can be a dedicated control channel (DCCH, Dedicated Control Channel). ).
