Abstract: Methods and apparatus for providing enhanced access options for wireless access points (e.g., cellular femtocells). These access options in one embodiment include various grades or levels of private and public access to available femtocell services. Each service may be separately assigned a various access type, such that a femtocell may service multiple users both within the “closed” group authorized by the femtocell white list, and non-members. In one variant, a femtocell broadcasts enhanced system information to all terminals (regardless of member/non-member status) such that a non-CSG (Closed Subscriber Group) member terminal or UE is capable of obtaining partial service access within the femtocell. Broadcast multimedia or other services can be delivered to both CSG members and non-members, advantageously without having to establish a dedicated connection for the non-member users.

Abstract: Wireless communication devices may directly communicate within groups of wireless communication devices using Layer-2 communications to implement “push-to-talk” type applications. In one implementation, a method may include generating a floor request signaling message to take control of a communication channel for a group. After transmitting data relating to the communications, a floor release signaling message may be generated and transmitted a number of times.

Abstract: Methods and apparatus enabling a wireless network to optimize paging channel operation, based on mobile device context information. In one embodiment, the wireless network is a cellular network (e.g., LTE-Advanced), and both base stations and cellular user devices dynamically exchange and maintain a paging agreement. The paging agreement limits the paging channel operation, thereby minimizing unnecessary scanning and usage of irrelevant radio resources. Such paging mechanisms ate limited to the air interface between the base station and the mobile device, and are compatible with existing legacy devices and network entities. Networks with appropriately enabled user devices may improve their resource utilization. Base stations may advantageously reclaim freed-up cellular resources to support other services.

Abstract: Methods and apparatus enabling a wireless network to generate data that can be used by a receiver (e.g., UE) to resolve the contributions of individual transmitters, such as to determine its location without resort to external devices such as GPS satellites. In one embodiment, the wireless network comprises a single frequency network (SFN), and a unique base station identifier is embedded within the data, and encoded in a manner which allows the UE to calculate path characteristics (such as path latency, and Direction of Arrival) to triangulate its position. In one variant, the data encoding comprises weighting frames of data from different base stations using an orthogonal matrix. Advantageously, the encoding and embedded identifier are also transparent to legacy UE, thereby allowing for implementation with no infrastructure or UE modifications other than software. Network and user apparatus implementing these methodologies, and methods of doing business, are also disclosed.

Abstract translation: 基于移动设备上下文信息，使无线网络能够优化寻呼信道操作的方法和装置。 在一个实施例中，无线网络是蜂窝网络（例如，LTE-Advanced），并且基站和蜂窝用户设备都动态地交换和维护寻呼协议。 寻呼协议限制了寻呼信道的操作，从而使不必要的无线资源的扫描和使用最小化。 这种寻呼机制限于基站和移动设备之间的空中接口，并且与现有的传统设备和网络实体兼容。 具有适当启用的用户设备的网络可能会提高其资源利用率。 基站可以有利地回收释放的蜂窝资源以支持其他服务。

Abstract: Methods and apparatus that enable one or more wireless networks to minimize inter-cellular interference (ICI) at a receiver. In one embodiment, the network comprises an OFDM-based cellular network, and the method comprises utilizing a priori knowledge of non-data portions of signals from multiple base stations in order to schedule transmissions. In one variant, these non-data portions comprise pilot tones; the pilot tones can be scheduled onto various time-frequency resources of the network so as to minimize ICI. The mobility context of the receiver can also be used as a basis for dynamically adjusting the pilot tone density. In another variant, precoding (e.g., Tomlinson-Harashima precoding) can be applied to “shape” the non-data portions of the transmitted signals so as to mitigate ICI. In yet other variants, frame preambles and learning sequences are used as the basis for invoking selective transmission time shifts across the potentially interfering base stations so as to minimize ICI.

Abstract: Methods and apparatus that provide user access control within wireless networks such as those having both fixed and portable nodes. In one embodiment, the network comprises a 3G cellular network or Interworking WLAN (iWLAN), and the portable nodes comprise Home Node B (HNB) base stations. The HNB is configured to authenticate new users, and provide network access while still maintaining user privacy. The portable nodes also may operate in a number of different operating modes which provide different functional control over user access. In one variant, an easy-to-use owner-assigned ID based access control mechanism with a reliable unambiguous user ID is utilized. Methods for providing access control across differing network architectures and protocols, such the aforementioned iWLAN, and business methods, are also described.
