Patent number: 8437311Abstract: A pilot-measurement control method and a dual-mode terminal are provided. After entering a tunnel state, an idle state protocol submodule does not wait for a measurement start command to trigger pilot measurement, but instead, directly triggers pilot measurement by actively searching for high rate packet data (HRPD) measurement permission variable information. Alternatively, measurement indication information sent by an initialization protocol submodule is buffered in advance, so that after entering the tunnel state, the idle state protocol submodule can trigger pilot measurement by searching for the buffered information. Alternatively, the idle state protocol submodule performs pilot measurement according to received measurement indication information sent by an air interface connection management protocol submodule when the idle state protocol submodule is activated.Type: GrantFiled: May 27, 2011Date of Patent: May 7, 2013Assignee: Huawei Technologies Co., Ltd.Inventors: Minzhi Deng, Mingxia Xu, Xin Zhong, Shuhui Hu

Patent number: 8229474Abstract: A system and method for terminal access includes transmitting a paging message from a network to a terminal; determining, by the terminal, orthogonal code information which differs from the one being used for current system access according to a predetermined rule; acquiring by the terminal a corresponding orthogonal code according to the orthogonal code information and modulating an access probe according to the orthogonal code; and transmitting the access probe by the terminal to the network and performing network access. In the various embodiments, the terminal responding to the paging selects a unique access orthogonal code according to the method and system. According to various embodiments, conflicts are minimized as a result of using the same orthogonal code between the terminals responding to the paging and between the terminal responding to the paging and the terminal originating the call. Accordingly, latency in the response to paging may be reduced.Type: GrantFiled: November 24, 2008Date of Patent: July 24, 2012Assignee: Huawei Technologies Co., Ltd.Inventors: Quanzhong Gao, Mingxia Xu

Patent number: 8050725Abstract: A method for paging access terminals. The method includes: a network entity sends a paging message to a target AN. The paging message carries the information required for calculating the time when the AT wakes to monitor the paging message. The information includes the absolute time that is determined according to the time when the AT previously shifts from the connected state to the idle state. Upon receipt of the paging message, the target AN determines when to send the paging message to the AT according to the information carried in the paging message. The present embodiments also disclose a system and apparatus for paging access terminals. The apparatus is a network entity that sends the paging message. The method, system and apparatus can be used to determine the time when the AT wakes to monitor the paging message, thus ensuring that the AT paging is not missed.Type: GrantFiled: March 31, 2009Date of Patent: November 1, 2011Assignee: Huawei Technologies Co., Ltd.Inventor: Mingxia Xu
