Disclosed are a method and a system for management of handover only trunk line between mobile switching centers for handover in a mixed mobile communication system of an asynchronous network and a synchronous network. The invention is performed to connect and disconnect a trunk line between asynchronous mobile switching centers and synchronous mobile switching centers, thereby sending and receiving of trunk line management messages wherein the message types are reset circuit message, blocking message, trunk test message and other additional types of message.

The present invention relates to a method of performing handover from an asynchronous mobile communication network to a synchronous mobile communication network. If the access network of the asynchronous mobile communication network (100) requests handover to an MSC (104) of the asynchronous mobile communication network, the MSC requests/receives subscriber information of the mobile communication terminal from a dual-stack HLR (300), and transmits a handover request message to the synchronous mobile communication network (200). The MSC (203) of the synchronous mobile communication network assigns a forward channel to the mobile communication terminal. The asynchronous mobile communication network (100) transmits a handover instruction message to the asynchronous RF device of the mobile communication terminal. Accordingly, the mobile communication terminal sets up a synchronous RF device, connects to the synchronous mobile communication network through reverse channel assignment and synchronization. The mobile communication terminal transmits a handover completion message to the synchronous mobile communication network.

In the mobile communication system, asynchronous and synchronous Mobile Switching Centers (MSCs) are interconnected via an Interworking Interoperability Function (IIF), and are connected to a Dual stack Home Location Register (D-HLR). The D-HLR stores and manages asynchronous subscription and synchronous subscription information of the mobile communication terminal. The IIF stores and manages the synchronous mobile communication system information, receives the synchronous subscription information of the mobile communication terminal from the D-HLR, transmits synchronous system information and the synchronous subscription information of the mobile communication terminal to the synchronous MSC and receives a response from the synchronous MSC, and requests the asynchronous MSC to release a wireless connection when the mobile communication terminal and the synchronous mobile communication system are interconnected and notification of completion of the handover is provided.

In the mobile communication system, asynchronous and synchronous Mobile Switching Centers (MSCs) are interconnected via an Interworking Interoperability Function (HF), and are connected to a Dual stack Home Location Register (D-HLR). The D-HLR stores and manages asynchronous subscription and synchronous subscription information of the mobile communication terminal. The HF stores and manages the synchronous mobile communication system information, receives the synchronous subscription information of the mobile communication terminal from the D-HLR, transmits synchronous system information and the synchronous subscription information of the mobile communication terminal to the synchronous MSC and receives a response from the synchronous MSC, and requests the asynchronous MSC to release a wireless connection when the mobile communication terminal and the synchronous mobile communication system are interconnected and notification of completion of the handover is provided.

A method and apparatus for a called subscriber to send a sound for his own personal information as a ringback tone with a ringback tone replacing sound are disclosed. The method comprises the steps of: HLR providing MSC with the first information about whether a ringback tone is to be replaced or not and the second information for routing to sound providing means when a called terminal is registered in MSC; MSC requesting a call connection to the sound providing means based on the first and second information when the called terminal is called; and the sound providing means call-connecting to the calling terminal, and providing the calling terminal with a specific sound, wherein the specific sound is generated by combining a subscriber information sound, which can identify the called subscriber or can represent the subscriber's character, with the ringback tone replacing sound.

Disclosed herein are a system and method for transferring voice messages. The system includes a voice message server. When a voice message and called terminal information are transmitted from a calling terminal, the voice message server stores the voice message, searches for a connection mute to the called terminal with reference to the called terminal information, and transmits a reception request signal to the called terminal. Furthermore, when the called terminal responds to the reception request signal, the voice message server reproduces the voice message. Furthermore, when the called terminal does not respond to the reception request signal and the reception request signal is forwarded to a different receiving object, the voice message server checks whether the route of the reception request signal has been changed and interrupts the transmission of the voice message. Accordingly, an additional communication charge may be avoided.

Disclosed are a voice message transmission system, transmission result notification system and methods thereof. A transmission terminal records a voice message and receiving terminal information. An IP server recognizes the record of a voice message and generates a communication path to the receiving terminal corresponding to the receiving terminal information. After detecting a voice message reception notification signal from the receiving terminal, the IP server provides the receiving terminal with the voice message. In the present invention, a receiver can listen to the voice message without manipulating a key. Thus, the present invention can increase the convenience in using a voice mailbox server.

The present invention relates to a method for processing an address of a short message service center in a WCDMA network, including: a load centralization confirmation step where an operation control unit receives short message processing states from each short message service center, confirms load centralization states of each short message service center, and generates an operation message; a path setup step where a mobile switching center receives a short message from a mobile station, and sets up a transmission path of the short message according to the operation message; and an optimal transmission step where the mobile switching center transmits the short message from the mobile station to the corresponding short message service center through the transmission path according to the result of the path setup step. When a lot of messages are centralized to a specific short message service center due to call habits of subscribers, some subscribers of the short message service center arc distributed to another short message service center, and thus service center reception ability is predictable. It is also possible to actively cope with civil appeals and troubles.
