    Description

    Technical Field



    [0001] The present invention relates to an application method for value-added services in the communication field (including mobile communication and wireline communication), and especially, relates to a system and a method for playing coloring ring back tone based on a user's presence information in the communication field.

    Background Art



    [0002] Coloring ring back tone service is called as coloring ring back tone (short for CRBT) service, which refers to that after a called user conducts relevant setting, when other users make calls, before the called user (i.e. MT (Mobile Terminal)) answers the call, the system will play a piece of music, advertisement or the message left by the called user to a calling user (i.e. MO (Mobile Originate))according to the called user's relevant setting, and then what the calling user hears is no longer the dull ring back tone of "toot, toot" as we usually heard before, but the ring back tone set by the called user in the system, i.e., the coloring ring back tone. What needs to be pointed out is that those personalized coloring ring back tones are set by the called user in advance, which can be the ring or music provided by the system, or a voice document recorded by the called user through an intelligent network system in advance, or a voice document downloaded by the called user to the intelligent network system from the network in advance. Since the development of the coloring ring back tone service, it has been very popular with users, operators, content providers, service providers and solution settlement device providers devote a great amount of manpower and material resources to the service, which offers strong support to the service development, and raises a lot of valuable reference designs and solutions, and especially, the solutions, such as how to let users set their coloring ring back tones and what contents they can set, how to maximize the users' personalities and meanwhile pays attention to the realization of the operator's system such as how to effectively cooperate with the service provider and the content provider, are basically accepted by the operators and providers after repeated amendments and have been commercialized, and the good commercial effect renders the wide use of the coloring ring back tone service in the country. Not only the mobile operators deploy the coloring ring back tone service, the wireline operators also deploy the corresponding service, and even the personal handyphone system (short for PHS) is deployed with the coloring ring back tone service, so it can be seen that the value-added service is widely favored by users and operators.

    [0003] Prior art document WO03096709 A2 discloses a system and related method for supporting non-intrusive and effective voice communication among mobile users in which voice calls between mobile users are managed based on callee availability, caller-callee relationships, and non-intrusive information exchange, including interactive exchange at the time of call setup but prior to the call being answered. Callee availability can be based on callee device status, calendar activities, location, past behavior and other factors. The caller-callee relationships specify whether the callee is available, unavailable or on restricted availability relative to the caller. The interactive exchange can be implemented using voice and/or text/graphic displays on caller and callee mobile device. Callees are provided with options for handling the call. Callers are provided with information regarding the callee's current and future availability and willingness to receive a voice call from the caller, thus maximizing the chance of caller reaching the callee on every voice call.

    [0004] A prior art, WO2004102940A1 discloses a system and method for providing RBT in communication network, particularly, in the GSM network and the CDMA network. In its embodiments of the specification, the called MSC (T_MSC) pages the called terminal and transmits the presence information of the called terminal to the RBTS by ACM. Then, the RBTS judges whether current state of the called terminal is idle according to the ACM, wherein if yes, the RBTS plays the customized ring back tone; if no, such as the called terminal is in busy, power off or out of service area, the RBTS sends to the calling terminal the voice information which represents the called terminal being busy, power off or out of the service area.

    [0005] Although this prior art provides a technical solution for providing RBT in communication network, it fails to meet the requirement of providing personalized service when using the RBT. With the development of the communication technology, especially the development of the technology and value-added services in mobile communication field, the network structure can support various kinds of value-added services, for example, the IP multimedia subsystem (short for IMS) is raised to integrate the prior networks in order to provide enough network capacity to support new value-added services. No matter the mobile operator or the wireline operator, both of them hope to improve their profits and the average revenue per user (short for ARPU) value through the value-added services, therefore, the saying of "service is the king" emerges. After several years' development, the coloring ring back tone service has been widely accepted, users hope to express their mood or feeling to a certain extent through the coloring ring back tone, and it is a non face-to-face expression manner. Just because of this characteristic, users love the coloring ring back tone service very much. Therefore, it becomes the key problem in developing the prior coloring ring back tone service and making more users accept the coloring ring back tone service that new attributes of the coloring ring back tone should be developed, lifecycle of the service should be extended, and innovative points be found.
