An objective of the invention is to provide methods and apparatuses for providing timing functionality for a system where processing is separated from data. The invention introduces a cloud timer at least including a first node and a second node. The first node is configured to receive a timer start request from a worker, the timer start request including an identifier of a timer, an expiration time, and an identifier of a notified object; and the second node is configured to, in response to reaching the expiration time of the timer, send a timer expiration notification to a network entity corresponding to the identifier of the notified. Compared with the prior art, the invention does not compromise the design principle of the Worker-State model; besides, a starter of the timer may designate an object to be notified when the timer is expired and information carried in the timer expiration notification, which compensates the drawbacks in the prior art. In addition, the design of cloud timer adopts a principle of multi-node redundant backup, which conforms to the design concept of a cloud computing environment.

The embodiment of the present invention discloses a data processing method and user equipment, relates to the technical field of communication, and can solve the problem of low success rate of UE accessing a network. The method includes: when the time domain resource of the data channel overlaps with the time domain resource of the control channel, and the relationship between the first information and the second information is a target relationship, according to the detection result of the LBT detection on the target subband, according to The target processing method corresponding to the detection result is processed; wherein, the target processing method can be any of the following: the target information carried on the control channel is transmitted on the data channel, and the control channel is not sent; the target information is carried on the Send on the control channel and not send the data channel; not send the data channel and the control channel; send the data channel and not send the control channel and the target information. The embodiment of the present invention is applied in the process of UE processing data according to the target processing mode.

The invention discloses a data packet sending method and device, which are used to solve the problem of randomly selecting the sending time slots of data packets in all time slots corresponding to the allowable range of the maximum sending delay of data packets in a vehicle-road cooperative communication system. An abnormality occurs in the sending time slot, so that the data packet cannot be successfully sent out in time within the allowable range of the above-mentioned maximum sending delay, which affects the reliability and security of the system. The method is: based on the SU-ALOHA algorithm, set the corresponding delay margin value according to the data packet transmission priority corresponding to the data packet; according to the delay margin value and the maximum transmission delay information of the data packet carried in the data packet, calculate The remaining time for sending the data packet; sending the above data packet by using the above remaining time for sending.

The invention discloses a method and equipment for sending mail. The method includes: (a) extracting the mail address from the address column of the recipient; (b) detecting the mail address existing in the historical sending failure list from the extracted mail address; (c) delete the detected email address from the recipient address column; (d) send the email to the email address in the recipient address column. According to the present invention, the problem of mail sending failure due to wrong recipient address can be prevented, thereby increasing the success rate of mail sending.

Embodiments of the present invention disclose a method, device, and system for judging a random contention resolution. The method includes: sending a contention resolution request message to a network side, where the contention resolution request message carries a cell radio network temporary identifier (C-RNTI) or a common control channel serving data unit (CCCH SDU); and when receiving a network side message masked with a temporary C-RNTI (T C-RNTI) allocated by the network side to the UE before a CRT expires, performing backoff if judging, according to the C-RNTI or CCCH SDU and the signaling type of the network side message, that contention resolution fails.

The invention discloses a picture message safe transmission method and system based on a mobile device. Accordingly to the method, firstly, the information input by a sending terminal is firstly intercepted and whether the information is a picture is determined; if the information is not a picture, the message is not encrypted; if the information is an image, the following steps are performed on the picture: the input picture is encrypted to obtain an encrypted file, and the encrypted file is sent to a self-built server; at the same time, a blank picture corresponding to the input picture is generated and the blank picture is sent to an instant messaging server; the receiving terminal receives and displays the blank picture sent by the instant messaging server; when the blank picture received by the receiving terminal is clicked, the encrypted file is downloaded from the self-built server; and the downloaded encrypted file is decrypted to display the input picture. The invention also discloses a corresponding system. The method and system of the invention can ensure the safety of the picture transmission process and avoid the situation that the encrypted file of the picture can notbe identified and the transmission fails.

The invention provides a number portability number management method and system, and the method comprises the steps: enabling an enterprise short message service number access number to access a service provider short message gateway, and enabling the number access service provider short message gateway to query an operator to which a certain mobile phone number belongs through a number portability number management center; judging whether an affiliated operator of the mobile phone number is queried or not; if yes, returning a query result, and sending a short message to the mobile phone of the user by the number access service provider short message gateway through the service provider short message service center; if not, copying the short message content needing to be sent to the number portability number management center, and sending the sent short message content to the user by the number portability number management center. According to the number portability number management method and the number portability number management system provided by the invention, the situation of short message sending failure caused by number portability can be effectively avoided; and a convenient and credible number portability number attribution input or change service is provided for a user or an operator, so that the problem that the user cannot normally receive a registration or notification service short message due to number portability can be avoided.

The embodiment of the invention relates to the technical field of wireless communication, particularly relates to a method and a device of the uplink power control, used for realizing the uplink power control of UE (user equipment) in a scene of inter-band CA. The method provided by the embodiment of the invention comprises the following steps: determining a transmitting power value of an uplink channel of each carrier wave by the user equipment; when the sum of the transmitting power values of all the uplink channels in all frequency bands is larger than the maximum transmitting power value allowed by the user equipment, reducing the power according to the maximum transmitting power value allowed by the user equipment and a power reduction proportionality factor corresponding to each frequency band so that the sum of the reduced transmitting power values of all uplink channels in all the frequency bands is not larger than the maximum transmitting power value allowed by the user equipment. The uplink power control of the UE can be realized in the scene of inter-band CA by adopting the method and the device provided by the embodiment of the invention.
