Description

TECHNICAL FIELD [0001] The present invention relates to a communication service control method and apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for controlling a communication service of a mobile terminal, and more particularly, to a technique for controlling a communication service of a mobile terminal in a LTE packet system providing a voice over LTE (VoLTE) The present invention relates to a communication service control method and apparatus for a mobile terminal, which is suitable for coordinating and providing various VoLTE-related services optimized from a server point of view.

As is well known, a 3rd Generation Partnership Project (3GPP) mobile communication system based on a WCDMA (Wideband Code Division Multiple Access) radio access technology is widely deployed all over the world, and the first evolutionary stage of WCDMA HSDPA (High Speed Downlink Packet Access), which can be defined as a high-speed wireless communication system, provides a 3GPP mobile communication system with high-competitive wireless access technology in the mid-term future.

However, as the requirements and expectations of users and operators continue to increase and competition for development of wireless access technologies continues, there is a need to evolve new technologies in 3GPP mobile communication systems in order to gain competitiveness in the future. That is, a reduction in cost per bit, an increase in service availability, the use of a flexible frequency band, a simple structure and an open interface, and an appropriate power consumption of a UE are required. In addition, prevention of unnecessary latency at the network node and efficient use of network resources can also promote the technology evolution in 3GPP.

In 3GPP Release 8, EPC, which is a network architecture, is described as one of mobile communication systems for meeting the above-mentioned requirements. The EPC is a collection of network nodes for the 3GPP LTE system. The EPC supports the evolution of the core network of the existing 3GPP system architecture, supporting the evolved RAN (E-UTRAN), and the efficient network structure that simplifies the network node to increase the efficiency of the packet network. . A wireless communication system including an EPC and an E-UTRAN may be referred to as an EPS (Evolved Packet System) and corresponds to an LTE mobile communication system currently being implemented and serviced in Korea.

On the other hand, the VoLTE service such as high-quality / high-quality call and voice / video call switching can determine whether a service is available between a calling terminal and a called terminal, and use the related service according to the determination result.

That is, the calling terminal generates a SIP request message (or an INVITE message) including a VoLTE call enable message, a call transfer enable message, and the like, and transmits a multimedia session control system (MSS), a telephony application server (TAS) (Or a 200 OK message) including a VoLTE call enabled, a call transfer enabled, and the like, and transmits it to a multimedia session control system (MSS) to a telephony application (TAS) server to a calling terminal via a communication path via a multimedia session control system (MSS), whereby the calling terminal determines whether VoLTE call service, call transfer service, and the like are possible with the called terminal.

That is, conventionally, the mobile terminal determines whether the VoLTE communication service is available through a message exchange between the calling terminal and the called terminal. At this time, the inter-protocol multimedia subsystem (IMS) network does not participate in the VoLTE communication service at all.

Korean Patent Publication No. 10-2008-0099620, published on November 13, 2008.

However, the conventional method of determining whether the VoLTE communication service can be performed through the exchange of messages between the terminals requires a VoLTE service even if the call is originated or received through a global common standard terminal (i.e., a foreign terminal) And if a new VoLTE service is added to the IMS network in the future, the added service can not be used unless the mobile terminal is changed.

Considering that a larger number of VoLTE terminals can be mass-produced in the future and that a network operator can continuously develop and provide new VoLTE services, the problems of the conventional method will become even more fatal.

Accordingly, there is a need for a new service model that can overcome the problems of the conventional method. However, at present, there is no suggestion for the new service model.
