Access to femto cell service can be managed through access control list(s) (e.g., white list(s), or black list(s)). White list(s) includes a set of subscriber station(s) identifier numbers, codes, or tokens, and also can include additional fields for femto cell access management based on desired complexity. White list(s) can have associated white list profile(s) therewith to establish logic of femto coverage access based on the white list(s). Values of attribute fields that determine white list(s), black list(s), or white list profile(s) can be generated through various sources. An access list management component facilitates generation and maintenance of white list(s), black list(s), or white list profile(s). Values for identifier attribute field(s) available for inclusion in a white list are validated prior to inclusion therein. Various example aspects such as white list(s) management, maintenance and dissemination; automatic population or pre-configuration; and inclusion of wireless device(s) or subscriber(s) are also provided.

A femto cell service framework is utilized for purchase and service of femtocell equipment and customer support thereof. A point of sale (POS) platform enables purchase of femtocell equipment based on a set of eligibility criteria. POS also allows purchase of add-on services. Direct fulfillment and post-sale transactions such as returns and equipment replacement are also provided. An account management service enables femtocell equipment and service self-care or through customer representatives. Configuration of service account and monitoring of account status is provided. Customer care architecture also enables remote troubleshooting of purchased equipment. Remote troubleshooting includes diagnosis and related manipulation of purchased equipment.

Access management to femto cell service is provided through access control list(s) (e.g., white list(s), or black list(s)). White list(s) includes a set of subscriber station(s) identifier numbers, codes, or tokens, and also can include additional fields for femto cell access management based on desired complexity. White list(s) can have associated white list profile(s) therewith to establish logic of femto coverage access based on the white list(s). A mechanism for reciprocal addition of access field attributes in access control lists and white list profiles also is provided. The mechanism allows at least in part for a first subscriber to be added to a configured white list of a second subscriber, when the first subscriber configures a new white list, the second subscriber is reciprocally incorporated in the new white list. Such mechanism can be driven and facilitates generation of associations among groups of subscribers that share specific commonalities.

Traffic and signaling are routed between a set of networked femto access points (APs) and location-based services are enabled. A femto AP in the set of femto APs is functionally linked to a routing platform that manages traffic and signaling, and is functionally connected to a controller component that relays at least part of data and control to a femto network platform. The femto network platform allows access to one or more external networks. Routing platform can exchange signaling with one or more femto APs to enable, at least in part, location-based services based at least in part on identifier(s) for a femto AP, access privileges, or time-of-flight measurements that assess propagation timing between a mobile device and a femto AP. Routing platform can supply timing configuration to enable predetermined spatial resolution of location estimates. Location estimates can be recorded and conveyed to a consumer layer.

The deployment of long term evolution (LTE) in the unlicensed spectrum (LTE-U) has been gaining significant industry momentum in recent months. The US 5-GHz Unlicensed National Information Infrastructure (UNII) bands that are currently under consideration for LTE deployment in the unlicensed spectrum contain only a limited number of 20 MHZ channels. Thus, in a dense multi-operator deployment scenario, one or more LTE-U small cells have to coexist and share the same 20 MHz unlicensed channel with each other and with the incumbent Wi-Fi. In this paper, we present the scenario and demonstrate that in the absence of an explicit interference mitigation mechanism, there will be a significant degradation in the overall LTE-U system performance for LTE-U cochannel coexistence in countries that do not mandate listen-before-talk (LBT) requirements. We then present the unlicensed spectrum intercell interference co-ordination (usICIC) mechanism as a time-domain multiplexing technique for interference mitigation for the sharing of an unlicensed channel by multioperator LTE-U small cells. Through extensive simulation results, we also demonstrate that our proposed usICIC mechanism will result in 40% or more improvement in overall LTE-U system performance.

The method provides power control in transmitting a downlink signal of frame data in a wireless network. Each frame is composed of timeslots, with each timeslot being further composed of quarter symbols. The method includes mapping each quarter symbol to an offset within a frame attenuation buffer, and computing a template for the frame, each step being performed only once. The template is used for filling the attenuation buffer with attenuation values to attenuate the transmit power for the downlink signal. Attenuation values are provided for each quarter symbol in a frame, although a computation is not required for each quarter symbol. The attenuation values are grouped in blocks that are recursively copied into the frame attenuation buffer based on the template. The contents of a filled attenuation buffer are output for use in attenuating the transmit power of the frame.

A computer-implemented system and method for a lock-less, zero data copy messaging mechanism in a multi-core processor for use on a modem in a telecommunications network are described herein. The method includes, for each of a plurality of processing cores, acquiring a kernel to user-space (K-U) mapped buffer and corresponding buffer descriptor, inserting a data packet into the buffer; and inserting the buffer descriptor into a circular buffer. The method further includes creating a frame descriptor containing the K-U mapped buffer pointer, inserting the frame descriptor onto a frame queue specified by a dynamic PCD rule mapping IP addresses to frame queues, and creating a buffer descriptor from the frame descriptor.

A system for providing multi-cell support within a single SMP partition in a telecommunications network is disclosed. The typically includes a modem board and a multi-core processor having a plurality of processor cores, wherein the multi-core processor is configured to disable non-essential interrupts arriving on a plurality of data plane cores and route the non-essential interrupts to a plurality of control plane cores. Optionally, the multi-core processor may be configured so that all non-real-time threads and processes are bound to processor cores that are dedicated for all control plane activities and processor cores that are dedicated for all data plane activities will not host or run any threads that are not directly needed for data path implementation or Layer 2 processing.

User equipment aggregates connections in at least one of a first unlicensed frequency band and a second unlicensed frequency band with a connection in a licensed frequency band to form a wireless backhaul connection to the user equipment. The user equipment selectively allocates a third unlicensed frequency band to a tethering connection.
