Patent number: 8279845Abstract: A system for realizing the reception of a incoming call number by a terminal includes a CDMA network and a HRPD network providing service support for the terminal, respectively, where an MSC in the CDMA network connects with an access network of the HRPD network via interface A1. A method for realizing the reception of a incoming call number by a terminal in advance includes: the MSC in the CDMA network transmitting the incoming call number of a paging to the access network of the HRPD network through interface A1; the access network forwarding the incoming call number of this paging to the called terminal; the called user deciding whether to accept the incoming call based on the received incoming call number. Accordingly, the switching between HRPD and CDMA2000 1x can be avoided when the user decides not to accept the incoming call.Type: GrantFiled: August 1, 2005Date of Patent: October 2, 2012Assignee: Huawei Technologies Co., Ltd.Inventors: Ying Tan, Tianzhen Huang, Shikui Guo, Yongjian Mou, Shoubo Xie, Sihong Zhou

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: 7515906Abstract: Disclosed is a method for implementing authentication of high rate packet data (HRPD) services, applicable to multi-mode networks including IS95/CDMA2000 1x and CDMA2000 HRPD networks. The method includes an Access Terminal (AT) using the user information in the User Identity Module (UIM) as the user identifier and starting an authentication in accordance with the Extended Authentication Protocol (EAP). A Mobile Switching Center (MSC)/Visiting Location Register (VLR) obtains a random number and a first authentication number based on the user identifier, and the AT calculates a second authentication number based on said random number. The MSC/VLR compares the first authentication number with the second authentication number to determine whether they are consistent. If consistent, the authentication is successful. Otherwise, the authentication is aborted. With the disclosed method, authentication can be made by using the original MSC and HLR/AC in the CDMA IS95 or CDMA2000 1x network.Type: GrantFiled: November 15, 2005Date of Patent: April 7, 2009Assignee: Huawei Technologies Co., Ltd.Inventors: Fengshao Zou, Wenxian Li, Zhuo Li, Jianghai Gao, Shikui Guo
