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.

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.

摘要:
Disclosed is a push-to-talk-over-cellular (PoC) service that transmits information on a group talk in a wireless connection section for operation in a mobile environment with a low traffic burden and higher efficiency. The PoC service transmits a PoC call request message of an originating PoC client to a terminating PoC server, receives a response message to the PoC call request message from a terminating PoC client, and receives a message including information of the terminating PoC client transmitting the response message, from an originating PoC server.
