摘要： An access node receives a device beacon transmitted from a wireless communication device in accordance with a system timing of a wireless wide area network (WWAN). When transmitted within a WWAN uplink channel, the device beacon is mapped to designated beacon channels within the time-frequency space of the uplink WWAN channel assignment. In response to the reception of the device beacon, communications between the wireless communication device and the access node are established. In one example, the access node is a femtocell base station. In another example, the access node is a wireless local area network (WLAN) access point.

摘要： A communication system includes at least a large service area (LSA) base station having a LSA geographical service area and a small service area (SSA) base station having a SSA geographical service area that is smaller than the LSA geographical service area and at least partially overlaps the LSA geographical service area in an overlap region. The LSA base station is configured to provide wireless service to first mobile communication devices which includes exchanging communication data. The SSA base station is configured to provide wireless service to second mobile communication devices which includes exchanging other communication data. Primary synchronization information is required by a mobile communication device for communication with the LSA base station and for communication with the SSA base station. Secondary synchronization information is required by a mobile communication device for communication with the LSA base station and tertiary synchronization information is required by a mobile communication device for communication with the SSA base station. A controller in the system allocates transmission of the primary synchronization information from at least one of the base stations over a physical channel having a defined transmission time and transmission frequency. If transmission of the primary synchronization information is allocated from both base stations, the primary synchronization information is allocated for transmission by the LSA base station and the SSA base station over the first physical channel. The controller also allocates transmission of the secondary synchronization information from at least one of the base stations over a second physical channel having a second defined transmission time and second transmission frequency. If transmission of the secondary synchronization information is allocated from both base stations, the secondary synchronization information is allocated for transmission by the LSA base station and the SSA base station over the second physical channel.

摘要： A mesh network communication system includes a plurality of access points connected to a wireless local area network (WLAN) controller where at least one of the plurality access points is a detection access point (DAP) that receives reverse link (RL) wireless wide area network (WWAN) signals transmitted from a multi-mode wireless communication device. Based on an intercepted RL WWAN signal, the DAP forwards reverse link (RL) information to the WLAN controller. Based on the RL information, the WLAN controller generates and sends, to the WWAN communication system, a device to access point association list (device-AP association list) comprising one or more device identifiers associated with one or more target access point identifier. The device identifier uniquely identifies a multi-mode wireless communication device within a maximum proximity of a target access point identified by the target access point identifier. The WWAN system applies the device-AP association list to efficiently manage handoffs from the WWAN system to access points in the mesh network.

摘要： In response to detecting a call attempt for a priority call on the originating wireless network by an initiating access terminal, at least one active call having a priority level less than the priority call is transferred to an alternate technology wireless network. If a call attempt is placed when a transfer threshold has been exceeded, candidate transferring terminals are identified based on multi-mode capabilities and network conditions. One or more of the candidate transferring terminals engaged in calls that have a priority level less than the priority call are transferred from the originating wireless network to the alternate technology wireless network when the transfer threshold is exceeded.

摘要： Briefly, one way to minimize time and frequency uncertainties when synchronizing between a transmitter and a receiver is to use a position determining method such as global positioning system (GPS) to determine position and velocity. If position can be determined the delay between the transmitter and receiver can be estimated. Additionally, position information can be used to determine the probability that the signal received will be a reflected signal. If the transmitter and receiver are located in an area with obstructions between them then it is more likely that a signal received will be a reflected signal. If it is determined that it is likely that the signal received will be a reflected signal then the receiver can attempt to acquire the transmitted signal over a wider range of propagation delay possibilities. Additionally, another uncertainty that complicates synchronization is uncertainty regarding frequency. One cause for frequency uncertainty is Doppler shift due to movement of the transmitter or receiver. Using a position determining method such as GPS to determine velocity allows the receiver to estimate the Doppler frequency shift and adjust for it.
摘要翻译：简而言之，在发射机和接收机之间同步时最小化时间和频率不确定性的一种方法是使用诸如全球定位系统（GPS）的位置确定方法来确定位置和速度。如果可以确定位置，则可以估计发射机和接收机之间的延迟。另外，可以使用位置信息来确定所接收的信号将是反射信号的概率。如果发射机和接收机位于它们之间的具有障碍物的区域中，则接收的信号更可能是反射信号。如果确定接收到的信号可能是反射信号，则接收机可以尝试在更广泛的传播延迟可能性范围内获取发送的信号。另外，使同步复杂化的另一种不确定性是频率的不确定性。频率不确定性的一个原因是由于发射机或接收机的移动引起的多普勒频移。使用诸如GPS的位置确定方法来确定速度允许接收机估计多普勒频移并对其进行调整。

摘要： In a wireless communication system, data is encoded by packet indifferent (PI) coding and some packets are transmitted omnidirectionally while supplemental packets are transmitted directionally to a user with a poor air link. PI encoding is defined herein as encoding in which the source data can be recovered from any K of the encoded packets, regardless of which of the encoded packets are received, where K=N+A. N is equal to the number of packets in the source data and A is the number of additional packets required due to the PI encoding. A subset of M data packets can be sent to one or many users from an omnidirectional antenna, where M is greater than or equal to K. If less than K data packets are received by at least one user, then the data block is not successfully received by that user. A number R of supplemental packets can be sent to users that did not receive K data packets successfully. The supplemental packets can be sent by a directional antenna to the specific user or users that did not receive K data packets.
摘要翻译：在无线通信系统中，通过分组无关（PI）编码对数据进行编码，并且一些分组被全向传输，而补充分组被定向地传送给具有差的空中链路的用户。 PI编码在这里被定义为可以从任何K个编码分组恢复源数据的编码，而不管接收到哪个编码分组，其中K = N + A。 N等于源数据中的数据包数，A是由于PI编码而需要的附加数据包的数量。 M数据分组的子集可以从全向天线发送给一个或多个用户，其中M大于或等于K.如果少于K个数据分组被至少一个用户接收，则数据块不成功由该用户接收。补充数据包R可以发送给没有成功接收K个数据包的用户。可以通过定向天线将补充分组发送给不接收K个数据分组的特定用户或用户。

摘要： A system and method are presented for determining when to exit an existing wireless communications coverage network. The method samples the device geographical position, determines a threshold boundary line, measures the position of each sample point with respect to the threshold boundary line, and, beginning at a predetermined initial value, maintains a running sum in response to measuring position. The method uses the threshold boundary line to partition a coverage area for the existing coverage network into first and second zones. Then, the method decrements the running sum for sample point positions in the first zone and increments the running sum sample point positions in the second zone. The method exits the existing coverage network when the running sum is greater than or equal to a predetermined terminal value and then resets the running sum to the predetermined initial value.
