Patent number: 7945267Abstract: A method for bearing voice data includes: a) a calling MSCe and the called MSCe determining that a calling MS and a called MS support the same voice coding and decoding type and that a call is a point-to-point call; b) the calling MSCe and the called MSCe sending Bearer Update Requests to the calling BSC and the called BSC, respectively; and c) the calling BSC and the called BSC setting up a voice bearer path between the calling MS and the called MS according to the requests from the MSCes. As a result, transparent transmission of voice data in a MGW is avoided so that transmission delay can be reduced and additional loading of the MGW can be avoided.Type: GrantFiled: March 25, 2008Date of Patent: May 17, 2011Assignee: Huawei Technologies Co., Ltd.Inventor: Qingshun Liu

Patent number: 7885670Abstract: The invention discloses a communication method of a dual-mode terminal, including: a Mobile Switch Centre (MSC) sends a message containing calling party information to an access functional entity of a High Rate Packet Data (HRPD) network via an InterWorking Solution (IWS) after receiving an initiated paging to a dual-mode terminal in the HRPD network; the access functional entity of the HRPD network sends a message containing the calling party information to the dual-mode terminal; the dual-mode terminal performs a subsequent communication according to the received calling party information. In the invention, upon receiving initiated paging from a dual-mode terminal in an HRPD network, the MSC sends a message containing the calling party information to an access functional entity of the HRPD network via the IWS, complexity of message processing is decreased, time of message processing is reduced.Type: GrantFiled: October 2, 2007Date of Patent: February 8, 2011Assignee: Huawei Technologies Co., Ltd.Inventors: Quanzhong Gao, Ying Tan, Shikui Guo, Qingshun Liu

Patent number: 7706389Abstract: A method for implementing the interaction of the IWF service data includes the steps of that: the base station controller encapsulates the PPP data bearing the IWF server data into the RTP packet data by defining the IWF data carry format between the base station and the media gateway; the interaction of the IWF service data between the base station and the IWF device is implemented based on encapsulated packet. The method of this invention solves the problem of that: after the A interface between the base station and the mobile switch center is standardized by IP, it can't support the IWF service, because of not defining the IWF data bearer format between the base station controller and media gateway logical interface in the prior art, this invention can support the IWF service, after A interface is standardized by IP.Type: GrantFiled: August 14, 2007Date of Patent: April 27, 2010Assignee: Huawei Technologies Co., Ltd.Inventor: Qingshun Liu
