Disclosed is a system and method for controlling Session Initiation Protocol (SIP)-specific event notification corresponding to an event subscription according to a preference of a subscriber. The system includes the subscriber requesting an event subscription through an event notification controller; a subscription target for notifying the subscriber of the event through the event notification controller in response to the event subscription request; and the event notification controller for controlling whether the event notification is forwarded to the subscriber according to the preference rules of the subscriber on event notifications. Accordingly, the event notifications to the subscriber can be effectively controlled according to the preference rules of the subscriber on event notifications, and it is possible to prevent the generation of unnecessary event notification that the subscriber does not desire.

Disclosed is a method for enabling a terminating-side PoC client to open a PoC session by using a pre-established session, and to maintain the pre-established session when the terminating-side PoC client terminates the open PoC session, and a PoC system and a PoC user equipment (UE) for implementing the same. To this end, a REFER BYE message is used to terminate the PoC session while keeping the pre-established session maintained. Also, the REFER BYE message is transmitted from the PoC client to the PoC server, and the PoC server receives the REFER BYE message, checks the contents of a header in the received message, and terminates the PoC session while keeping the pre-established session maintained when a specified condition is satisfied.

Disclosed is a method for enabling a receiving-side Push-To-Talk (PTT)-over-Cellular (PoC) user to acquire ad-hoc group invitee information and selectively establishing a PoC session according to preference when a pre-established session and an auto-answer mode have been set between a receiving-side PoC user equipment and a PoC server in a PoC system. Particularly, in order to efficiently utilize the receiving-side Session Initiation Protocol (SIP) session setting, disclosed are a solution for transferring information related to other users expected to participate in group communication through user-plane signaling, and in addition, access rules, service setting, timers and a method for changing a response set between the client and server in order to support the solution.

Disclosed are a location service providing system and a method for providing a triggered location request service. An H-SLP sets a priority order of a plurality of positioning methods which a target terminal supports according to a set priority order set condition and transmits priority order information according to respective positioning methods to the target terminal. Further, the target terminal may receive information about the positioning methods including the priority order and select a positioning method having the highest priority order among the positioning methods, which can be used in its current electric wave environment. Moreover, the H-SLP and the target terminal may calculate a location of the target terminal according to a positioning method that the target terminal has selected. Accordingly, although it is difficult to calculate the location of the target terminal according to the positioning method that the target terminal has selected, a location service of the target terminal can be continuously provided.

A positioning apparatus and method of a mobile terminal using a positioning server independently constructed on a network. The positioning apparatus includes a positioning server, independently constructed on a network, for collecting and storing/managing assistant data that includes orbit information and correction information of a satellite, and providing the assistant data or position information using the assistant data in response to an external request. The positioning server provides the position information of the terminal subject to positioning in response to the request for the position information of the terminal subject to positioning created from at least one network among a plurality of networks that share the positioning server. Accordingly, an accurate positioning result can be obtained with a cost for implementation of the positioning system reduced.

A method for managing a message thread including a series of messages transmitted to and received from a same counterpart by an Inter-Working Function (IWF) that interworks Converged Internet Protocol Messaging Service (CPMS) and another messaging service. The method comprises: receiving an SIP (Session Initiation Protocol) Converged Internet Protocol Messaging (CPM) message for a conversational message communication. The method further comprises: detecting a thread IDentification (ID) from the CPM message and storing the thread ID in a database. The method further comprises converting a message format of the CPM message into a message format that is supported in the another messaging service, wherein a recipient terminal of the CPM message is supported in the another messaging service, and transmitting the converted CPM message to another messaging service system. An IWF to implement the method is also disclosed.

Disclosed is an inter-entity coupling method for protecting content in a broadcast environment including a broadcast network and a terminal, the broadcast network having a Broadcast Service Application (BSA), a Broadcast Service Distribution (BSD), and a Broadcast Service Management (BSM), the inter-entity coupling method including performing, by the terminal, a registration process for obtaining a group key for the terminal; after the registration process is completed, performing, by the terminal, a service joining process for requesting service joining, and receiving, by the terminal, a Rights Object (RO) about the content from a message, which is received in response to the request, based on the obtained group key; obtaining a traffic key by using the RO, if a traffic key message is received after the service joining process is completed; receiving encrypted content in the terminal; and decrypting the encrypted content by using the traffic key.
