Description
Technical Field
The invention relates to the field of mobile communication, in particular to a method for displaying calling card information of a short message.
Background
The existing Calling Name Presentation (CNAP) technology is often applied to the field of call services, and is not well applied to the field of short message services, but in the current practical application scenario, when a user receives a short message, the user cannot acquire information capable of clearly identifying the identity of the sender, such as a Calling Name, sender head portrait information, and the like, and the reading and identifying efficiency is low.
Patent "incoming call name display method and apparatus of short message, storage medium, short message service center, receiving terminal" (CN202010475957), proposes a method for displaying incoming call name of short message:
the disadvantages of this patent are as follows:
the patent 1 adds an IE mode by modifying the communication protocol 23.040, that is, configuring caller id indication information in a protocol data unit of a short message transport layer to identify sending terminal Name information, but in the actual transmission process, adding an IE TP-Calling-Name-Presentation will occupy more air interface resources, which increases the network load.
2 the realization of the patent requires the cooperation of a short message center, but the realization of the patent is not well compatible with the condition that a receiving terminal does not support the calling name display of the short message. For the receiving terminal with lower software version, which does not support the caller ID display of the short message but receives the short message containing the caller ID display, the patent does not provide the processing mode of the receiving terminal
3 the patent improves the reading and identifying efficiency of the short message by increasing the display of the calling name of the short message, but the calling name method only supports the display of the text format.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The traditional Calling Line Identification Presentation (CLIP) service displays the number of a Calling party on a telephone display screen, a user can know the telephone number of a caller in advance before answering the call, with the technical progress, an operator provides a supplementary service similar to the CLIP service, namely Calling Name Presentation (CNAP) service, and provides an obvious information prompt function for the incoming call of a function service department or an advertising department, and the CNAP service provides a function of displaying the Name information of the Calling party to a called party when the incoming call is established. For example, after the user opens the service at the operator, the information of the CNAP service is set to "TestName" at the operator. When the user communicates with other users, if the mobile phone of the opposite side supports the CNAP function, the call interface is displayed as 'TestName' no matter whether the number is stored in the contact of the opposite side or not.
CNAP services are often applied to the field of telephony services, and the current display of the name of a short message incoming call only supports text formats. In addition, the traditional short message service may forge the number of the sender, and the identity information of the user of the sender cannot be effectively identified.
The technical problem to be solved by the invention is to provide a method for displaying calling card information of a short message, which can present a calling name, a head portrait picture of a sender, a short message sound and the like to a receiving terminal, improve the reading and identifying efficiency of the short message, avoid the appearance of short messages which falsify the identity information of the sender user, and avoid the need of carrying the head portrait picture, the short message sound and the like when sending the short message, thereby representing the identity information of the sender user and avoiding excessive occupation of air interface resources and increase of network transmission load. In addition, the condition that the short message of the calling name card cannot be analyzed due to the lower version of the software of the receiver can be compatible.
In order to achieve the above object, the present invention is characterized in that the method is as follows:
sender
And determining whether a sending terminal sending the short message registers incoming call business card user information display and permits the sender to display the incoming call business card information.
And configuring incoming call name card information existence indication information in the short message according to the determination result.
And sending the short message to a receiving terminal so that the receiving terminal determines whether the calling card information of the sending terminal is presented or not when the short message is displayed according to the calling card display indication information.
Receiving party
And receiving the short message configured with the incoming call name card indication information.
And analyzing the received short message, and if the receiving terminal can analyze the calling card display indication information, generating calling card URL information at the receiving terminal.
And the receiving terminal acquires the calling name card information of the sender from the short message service center through the URL.
The receiving terminal presents the caller card information of the sender while receiving the short message.
Fig. 1 is a sender processing flow of the incoming business card information display method of the short message according to the embodiment. Step S101 may be configured to determine whether a sending terminal sending a Short Message has registered incoming call card display information and whether to permit incoming call card information display by a Short Message Service-Service center (SMS-SC).
The step of determining whether to permit the caller card information display of the sender may multiplex the permission information signed by the sending terminal in the existing call service, such as a permission agreement or a permission term, so as to preliminarily determine whether the sending terminal can accept the caller card information presence indication information after sending the short message, according to whether the sending terminal permits the calling number display of the call service.
Further, the step of determining whether the sending terminal sending the short message registers incoming call card display information and whether to permit the incoming call card information to be displayed may include: through the mobile switching center, whether the sending terminal sending the short message has registered the user information of the calling name card and whether the display of the calling name card information is permitted is determined.
If it is determined that the short message sending terminal has registered the incoming call card information display and has permitted the incoming call card information display, the incoming call card presence indication information is configured in step S102. If the SMS terminal is not registered and/or the incoming calling card display indication information is not permitted, the step S102 (SMS center) configures the incoming calling card information non-existence indication information. In a specific implementation, the 8 th bit (bit 7), i.e., the reserved bit, of the first byte of the existing short message transmission (SMS-DELIVER Type) may be extended to the calling Card display Indication bit (TP-BCPI) in the existing short message transmission Type (belonging to the communication protocol 23.040). At step S102, the TP-BCPI value is set to 1, and at step S104, the TP-BCPI value is set to 0.
In step S103, the short message is sent to the receiving terminal, so that the receiving terminal determines whether to display the calling card of the sending terminal when displaying the short message according to the calling card display indication information.
Fig. 2 is a processing flow of a receiver of the incoming call business card information display method of the short message of the present invention. Step S201, a receiver receives a short message, wherein the short message contains the indication information of the existence of the calling card.
Step S202, analyzing the incoming call business card existence indication information.
Step S203, if the receiving terminal supports the analysis of the incoming call card presence indication information, the analysis of the incoming call card presence indication information of the received short message can be normally completed (TP-BCPI in SMS-delay), and if the receiving terminal cannot normally analyze the incoming call card presence indication information (for example, the receiving terminal software version is low, at this time, bit 8 (bit 7) of the first byte in SMS-delay is only Reserved bit), the receiving terminal does not perform any processing.
In step S204, it is determined whether the value of the indication information of the incoming name card of the received short message is 1. If the value is 1, go to step S205; if the value is not 1, the receiving terminal does nothing.
In step S205, the receiving terminal may generate the unique incoming name card identifier by using the sender Address TP-Originating-Address (K1 for short), the timestamp TP-Service-center-Time-Stamp (K2 for short) when the short message center SMC to which the short message sender belongs receives the message, and the short message content Length TP-User-Data-Length (K3 for short). The K1 may be forged when the actual short message is received. However, the private information of the short message service center, namely the private information of K2 and K3, has higher confidentiality and uniqueness in comparison with the 'verification code', and the short message service center can determine whether the requester receives the short message sent by the sender through K2 and K3. The receiving terminal generates an incoming call card information unique identifier K using K1, K2, K3.
In step S206, the receiving terminal generates URL information of the calling card through the public address information of the calling card and the unique identifier K of the calling card information generated in step S205, as shown in fig. 3. Examples are as follows: the public address information of the calling name card is https:// www.CommonSms.com/, the unique identifier of the calling name card is K, and the URL of the calling name card is https:// www.CommonSms.com/K
In step S207, the receiving terminal obtains the incoming call card information of the sender from the short message service center through the incoming call card URL information, referring to the processing flow of the short message service center in fig. 4.
In step S208, the terminal determines whether the calling card can be normally acquired through the calling card URL information, and if so, the process goes to step S213. If the incoming calling card acquisition fails, such as network delay, intermittent network failure, or the sms center refuses the access of the terminal, the process goes to step S209.
Step S209 starts the calling card acquisition timer TGet。
In step S210, if there is a delay in the network or the network is temporarily abnormal, the receiving terminal is at TGetThe calling name card information of the sender can not be obtained from the short message service center within the time, and the timer T is usedGetAnd when the time is out, the receiving terminal restarts the calling card acquisition timer and tries to acquire the calling card information of the sender from the short message service center, and in addition, the receiving terminal records the number of the calling card information acquisition attempts.
In step S211, the terminal determines whether the number of attempts to acquire incoming call card information reaches a maximum value Ntry。
In step S212, if the network delay is large or the network is abnormal for a long time (time is greater than T)Get*Ntry) Then, the receiving terminal gives up obtaining the calling name card information of the sender from the short message service center, displays the pre-stored calling name card information and the pre-stored calling nameThe film information can be the historical name card information of the sender, and the historical name card information is stored locally by the receiving terminal at intervals of TupdateThe time is updated by using the incoming call business card information which is acquired from the short message service center at the last time.
In step S213, the receiving terminal displays the incoming call card information acquired from the short message service device.
