Abstract
A point-to-point chat system and method are provided. The system comprises a USSD (Unstructured Supplementary Service Data) signaling interface unit and a chat control unit. The USSD signaling interface unit is configured to receive a USSD chat request message of an inviting party and a USSD chat joining message of an invited party via a core network, and to forward the USSD chat request message and the USSD chat joining message to the chat control unit. The chat control unit is configured to send a chat inviting message to the invited party after receiving the USSD chat request message, to start the chat after receiving the USSD chat joining message, and to receive chat information of the inviting party or the invited party to forward to the other party of the inviting party or the invited party.
Claims10
A point-to-point chat system comprising:
- a processor;
- a USSD signaling interface means;
- a chat control means;
- and
- a short message interface means;
- wherein the USSD signaling interface means is adapted for receiving a USSD chat request message of an inviting party via a Home Location Register (HLR) in a core network, and forwarding the USSD chat request message to the chat control means;
- the chat control means is adapted for:
- allocating a chat session code and a chat data block, and notifying the short message interface means to send a chat inviting message to the invited party after receiving the USSD chat request message;
- the short message interface means is adapted for sending the chat inviting message to the invited party via a short message center (SMSC);
- the USSD signaling interface means is further adapted for receiving a USSD chat joining message from the invited party via the HLR in the core network, and forwarding the USSD chat joining message to the chat control means;
- the chat control means is further adapted for, according to the allocated chat session code and the allocated chat data block, starting chat between the inviting party and the invited party after receiving the USSD chat joining message;
- and
- for receiving chat information which is forwarded by the USSD signaling interface means and is from the inviting party via the HLR and sending the received chat information from the inviting party to the invited party via the USSD signaling interface means and the HLR in turn, and receiving other chat information which is forwarded by the USSD signaling interface means and is from the invited party via the HLR and sending the received other chat information from the invited party to the inviting party via the USSD signaling interface means and the HLR in turn;
- wherein, the USSD signaling interface means is further adapted for:
- decoding the USSD chat request message, the USSD chat joining message and the chat information, which are forwarded to the chat control means, to extract data above a Signaling Connection Control Part (SCCP) layer therefrom and then encapsulating to compose a complete USSD data packet correspondingly;
- and for encapsulating the chat information which is sent to the HLR, into related underlying signaling protocol at the corresponding SCCP layer based on the allocated chat session code.

A point-to-point chat method comprising the following steps of:
- a USSD signaling interface means receiving a USSD chat request message of an inviting party via a Home Location Register (HLR) in a core network to send to a chat control means;
- the chat control means receiving the USSD chat request message from the USSD signaling interface means, allocating a chat session code and a chat data block, and notifying a short message interface means to send a chat inviting message to the invited party;
- the short message interface means sending the chat inviting message to the invited party via a short message center (SMSC);
- the USSD signaling interface means receiving a USSD chat joining message from the invited party via the HLR in the core network, and forwarding the USSD chat joining message to the chat control means;
- the chat control means receiving the USSD chat joining message of the invited party, and starting a chat between the inviting party and the invited party according to the allocated chat session code and the allocated chat data block;
- and
- the chat control means receiving chat information which is forwarded by the USSD signaling interface means and is from the inviting party or the invited party via the HLR;
- and
- sending the received chat information from the inviting party to the invited party via the USSD signaling interface means and the HLR in turn, and receiving other chat information which is forwarded by the USSD signaling interface means and is from the invited party via the HLR and sending the received other chat information from the invited party to the inviting party via the USSD signaling interface means and the HLR in turn;
- and
- the method further comprising:
- the USSD signaling interface means decoding the USSD chat request message, the USSD chat joining message and the chat information, which are forwarded to the chat control means, to extract data above a Signaling Connection Control Part (SCCP) layer therefrom and then encapsulating to compose a complete USSD data packet correspondingly;
- and
- the USSD signaling interface means encapsulating the chat information which is sent to the HLR, into related underlying signaling protocol at the corresponding SCCP layer based on the allocated chat session code.
