All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

The terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus. Furthermore, the use of "and/or" in the specification and claims means at least one of the connected objects, e.g., a and/or B, meaning that it includes a single a, a single B, and that there are three cases of a and B.

In the embodiments of the present application, words such as "exemplary" or "such as" are used to mean serving as examples, illustrations, or descriptions. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

It is noted that the techniques described in embodiments of the present application are not limited to long term evolution (Long Term Evolution, LTE)/LTE evolution (LTE-Advanced, LTE-a) systems, but may also be used in other wireless communication systems, such as code division multiple access (Code Division Multiple Access, CDMA), time division multiple access (Time Division Multiple Access, TDMA), frequency division multiple access (Frequency Division Multiple Access, FDMA), orthogonal frequency division multiple access (Orthogonal Frequency Division Multiple Access, OFDMA), single-carrier frequency division multiple access (Single-carrier Frequency-Division Multiple Access, SC-FDMA), and other systems. The terms "system" and "network" in embodiments of the present application are often used interchangeably, and the techniques described may be used for both the above-mentioned systems and radio technologies, as well as other systems and radio technologies. However, the following description describes a New air interface (NR) system for purposes of example, and NR terminology is used in much of the following description, although these techniques are also applicable to applications other than NR system applications, such as the 6th generation (6th Generation,6G) communication system.

The global system for mobile communications association (Groupe Speciale Mobile Association, GSMA) proposes the Rich media call (Rich paging) service concept in the converged communication (Rich CommunicationSuite, RCS) specification. The concepts of Pre-call, in-call and Post-call are presented for different phases of a call, respectively. The Pre-call service defines the ability of a calling party to push text, pictures, locations and important call marks to a called party before a call. In the international standard scheme, a calling user firstly sets pre-call information before making a call, then synchronizes to a called terminal through a message session relay protocol (Message Session Relay Protocol, MSRP) message tunnel, confirms that the terminal finishes information downloading, and makes a call to the called user.

For some calling business card services in the related art, there are the following problems:

(1) Requiring installation of APP or use of specific terminal to display caller information

(2) In addition, only simple enterprise calling name display is supported for the terminal non-local storage number, part of the enterprise logo can be displayed, information display such as text content and pictures is not supported, and multimedia information such as text content (such as conversation theme) and pictures before conversation with matched content cannot be set according to each telephone conversation condition.

For the scheme in the international standard, there are the following problems;

1. in the scheme in the existing international standard, only calling party setting call theme, picture and position information can be supported, and the display of calling party name is not supported.

2. The scheme in the existing international standard is based on MSRP tunnel for message transmission, and in two sessions with VoLTE/VoNR communication, the terminal is required to carry out service association according to certain logic, and the requirement on the terminal is higher.
