摘要： Methods and systems are provided for using femtocells to address macro-network backhaul congestion. In an embodiment, a macro base transceiver station (BTS) that has a backhaul connection to a radio network controller (RNC) detects that a current utilization of the backhaul exceeds a backhaul-congestion threshold, and responsively identifies one or more sector-carriers having a respective current air-interface utilization that is less than a respective sector-carrier-congestion threshold for the respective sector-carrier. The macro BTS further identifies one or more femtocells that are positioned in the coverage area of the one or more identified sector-carriers, and offloads some reverse-link traffic to each identified femtocell over the forward link of an identified sector-carrier in whose coverage area the respective identified femtocell is positioned, for forwarding of the offloaded traffic by the one or more identified femtocells over a packet-data network to an intended destination.

摘要： A method and system are provided for planning a service-provider network. The service-provider network includes a macro network and a number of low-cost internet base stations (LCIBs), where the macro network includes a number of macro base transceiver stations (BTSs). One or more LCIBs are selected. The selected LCIBs are instructed to operate in an unrestricted mode and then operate in the unrestricted mode for an evaluation period. After the evaluation period ends, an off-loaded-traffic amount is determined for at least a portion of the macro network for the evaluation period. The off-loaded-traffic amount is then associated with the one or more selected LCIBs. Then, the service-provider network is planned based on the off-loaded-traffic amount.

摘要： Methods and systems are disclosed that support the aggregation of acknowledgement messages and control messages. Advantageously, acknowledgement and negative acknowledgement indications for multiple client nodes are combined into a single aggregated message which is broadcast or multicast to the multiple client nodes. Based on unique identifiers assigned to each client node, client nodes are grouped such that the aggregated acknowledgement messages can be efficiently encoded to conserve both network capacity when they are transmitted, as well as processing capacity when they are parsed by the client nodes. If code division multiple access (CDMA) technology is used, the aggregated acknowledgment message can be transmitted without CDMA spreading to effectively broadcast or multicast it to multiple client nodes. A similar technique can be employed for the efficient broadcast or multicast of aggregated control messages.

摘要： The disclosure generally relates to service-tier-based regulation of reverse-link activity at an access terminal operating in a wireless access network. An exemplary method involves (a) receiving one or more reverse activity bits from a wireless access network; (b) based 5 at least in part on the received reverse activity bits, determining a Quick Reverse Activity Bit (QRAB) and/or a Filtered Reverse Activity Bit (FRAB); (c) applying a first service-tier filter to the determined QRAB, wherein the first service-tier filter corresponds to a service tier for which the access terminal is authorized; and (d) based at least in part on the service-tier filtered QRAB, determining an adjustment to reverse-link activity of the access terminal. The method may further involve applying a second service-tier filter to the determined FRAB and using the service-tier filtered QRAB in determining the adjustment to reverse-link activity.

摘要： A mobile station receives forward link signals and transmits reverse link signals for a communication session conducted via a wireless network. A controller maintains a reverse-active set that defines which sectors of the wireless network are used to receive the reverse link signals. When the mobile station transmits a request signal requesting the communication session, the controller may create the reverse-active set to include the sector that received the request signal with the highest signal strength. During the communication session, the signal strengths of the reverse link signals may be monitored in each of a plurality of sectors to obtain reverse-link signal strengths. The controller may maintain the reverse-active set based on the reverse-link signal strengths, adding sectors that report reverse-link signal strengths greater than an add threshold and dropping sectors that report reverse-link signal strengths less than a drop threshold.

摘要： In a wireless communication system, a wireless access node provides a wireless communication service to wireless communication devices over a first frequency band class and over a second frequency band class. A control system identifies a subset of the wireless communication devices operating over the first frequency band class that have been in an idle mode for a time period that exceeds a threshold. The wireless access node transfers a signal to the subset of the wireless communication devices to transition from the first frequency band class to the second frequency band class. The wireless access node then provides the wireless communication service to at least some of the subset of the wireless communication devices over the second frequency band class.

摘要： Methods and systems for triggering the delivery of a message waiting indicator (MWI) are introduced. In a wireless communication network, a radio access network (RAN) determines that a wireless communication device (WCD), such as a mobile phone, has missed an incoming call, and responsively: (i) routes the incoming call to a message storage system to enable an originator of the call to leave a message for a user of the WCD, (ii) waits a period of time after routing the incoming call to the message storage system, and (iii) then generates and transmits a message waiting query to the message storage system without prompting from the WCD. In response to the message waiting query, the message storage system may transmit a signal indicative of the message to the RAN. Responsively, the RAN may then transmit to the WCD a message waiting indication (MWI) indicative of the message, for presentation of the MWI to the user of the WCD.
