Abstract:
Systems and methods for limiting carrier aggregation for a wireless device are provided. A high mobility wireless device can be identified based on a number of carrier aggregation messages provided for the high mobility wireless device. An access node can receive a wireless device ID associated with the high mobility wireless device. The access node can obtain a wireless device ID from a wireless device being served by the access node. The wireless device ID of the served wireless device is compared with the wireless device ID of the high mobility wireless device. Carrier aggregation is denied based on the comparison.
Abstract:
Systems and methods for determining an access node for a wireless device are provided. A source signal level associated with a source access node and a target signal level associated with a target access node may be received from a wireless device. It may be determined that the second access node is operating in a power boosting mode. The wireless device may be instructed to continue communicating with the source access node when the target signal level exceeds the source signal level by less than a first criteria.
Abstract:
A first access node receives, from a wireless device, a first indicator. This first indicator corresponds to a downlink reference signal power as measured by the wireless device. The first indicator is associated with a second access node. The first access node determines a second indicator. The second indicator corresponds to an uplink reference signal power as measured by the first access node. The second indicator is associated with the wireless device. Based on the first indicator and the second indicator, a handoff of the wireless device from the first access node to a second access node is initiated.
Abstract:
A system and method of selecting an access node for communication in a wireless communication network are provided. A wireless device can receive a plurality of global cell identity messages, wherein each global cell identity message comprises an access node identifier. The wireless device can determine an access node classification for an access node associated with each global cell identity message. The access node classification can be determined based on each access node identifier. Each access node can be ranked based on the access node classification to determine a highest ranking access node. A signal characteristic of the highest ranking access node can be determined. Communication can be initiated with the highest ranking access node when the signal characteristic meets a threshold.
Abstract:
Systems and methods are described for determining an inter-frequency handover condition for a wireless device. A serving frequency for a location based service (LBS) operating on a wireless device at a first location may be determined. A controller node may determine a path for the wireless device. The path may begin at the first location and continue through a plurality of access node clusters. Each access node cluster may comprise a positioning reference signal (PRS) frequency. The PRS frequency of the access node clusters may be different from the serving frequency. A set of criteria for performing a handover from the serving frequency to the PRS frequency of the access node cluster may be determined. One of the criteria may be performing a periodicity scan of the LBS. An inter-frequency handover of the wireless device from the serving frequency to the PRS frequency of the access node cluster may be requested.
Abstract:
The delivery of paging messages to an access node are delayed based on an estimated paging message load currently being handled by the access node. When a mobility node receives a request that requires a wireless device to be paged, the mobility node refers to an estimate of the current paging load on an access node. This estimate can be based on the number of paging messages that have been sent to the access node that have not elicited a response and have not expired. If the estimated load is less than a threshold amount (e.g., 80%), then the paging message can be sent to the access node without further delay. If the estimated load is greater than the threshold amount, then an amount of time to wait before sending the paging message to the access node is selected or calculated.
Abstract:
In systems and methods of reducing wireless communication signaling overhead, it is determined that communication resource request traffic from a plurality of wireless devices in communication with an access node to communicate with a communication network meets a first threshold. One of the plurality of wireless devices is selected to operate as a router wireless device based on a power storage level and an assigned modulation and coding scheme of each of the plurality of wireless devices. At least one of the unselected wireless devices is instructed to communicate with the communication network via the selected router wireless device.
Abstract:
In systems and methods of tracking area configuration, a number of tracking area update messages received by a plurality of access nodes using a first tracking area configuration are monitored. It is determined that a number of tracking area update messages received by one of the plurality of access nodes meets an update message criteria. It is also determined that a number of connected wireless devices at the one of the plurality of access nodes meets a connection criteria. When the number of tracking area update messages meets the update message criteria and when the number of connected wireless devices meets the connection criteria, the second tracking area configuration is used at the access node.
Abstract:
Systems and methods are described for determining an access node for a wireless device. A first signal may be transmitted from a first access node with an increased signal level. An indication of a first adjustment factor based on the increased first signal level may also be transmitted from the first access node. Signal information may then be received from a wireless device, where the signal information includes a determined first signal level associated with the first access node and a determined second signal level associated with a second access node. The determined first signal level from the signal information may comprise a received signal level of the first signal decreased by the first adjustment factor. Based on the signal information, one of the first access node and the second access node may be selected for communication with the wireless device and the wireless device may be instructed to communicate with the selected access node.
Abstract:
Systems and methods are described for configuring a delay based scheduler for an access node. A plurality of packets may be received at an access node, where at least a first packet is associated with an application running on a wireless device in communication with the access node. The plurality of packets may be inspected to determine that one or more of the packets associated with the application are marked, where the mark indicates network congestion. A remaining time for the first packet may be calculated based on a packet delay budget associated with the running application and the determination that one or more of the packets associated with the application are marked. The first packet may then be scheduled for transmission to the wireless device, using a delay based scheduler, based on the calculated remaining time.
