Abstract: Systems and methods for operating a wireless communication system are provided. A network node can determine a first frequency band criteria and a second frequency band criteria based on information from an access node. The network node can determine a first timer duration of a first timer. The first timer duration can be based on the first frequency band criteria. The network node can determine a second timer duration of a second timer. The second timer can be based on the second frequency band criteria. The first timer duration can be different from the second timer duration. The access node can transmit the first timer duration and the second timer duration to the wireless device after the wireless device establishes communication with the access node.

Abstract: Systems and methods are described for identifying and resolving cell identifier confusion in a wireless network. A serving cell may determine that multiple neighboring cells have a duplicate cell identifier. The serving cells may receive signal measurement reports and network characteristics for the neighboring cells in order to determine if there is an opportunity for handover between the neighboring cells and the serving cell. If the multiple neighboring cells appear in a single signal measurement report from a single wireless device, there this is an opportunity for handover, and one of the neighboring cells may be instructed to change its cell identifier. However, the network characteristics indicate that the neighboring cell does not have coverage sector overlap, then there is no opportunity for handover and the neighboring cell may be removed from a database used by the serving cell during a handover process.

Abstract: When a first throughput between the wireless device and a first access node meets a threshold, an application requirement of an application running on the wireless device is determined. Measurements are received of a first signal level of the communication link between the wireless device and the first access node and a second signal level of a signal from a second access node received at the wireless device. A first data rate is estimated using a first communication scheme between the wireless device and the first and second access nodes, and a second data rate is estimated using a second communication scheme between the wireless device and the first and second access nodes. One of the communication schemes is selected for use by the wireless device and the first and second access nodes based on the estimated first data rate and the estimated second data rate and the application requirement.

Abstract: Systems and methods for operating a wireless communication system are provided. An access node can receive a multimedia broadcast multicast services data flow. The data flow can comprise a first data packet and a second data packet where the first data packet comprises a first transmission time and the second data packet comprises a second transmission time. The data flow can be stored in a buffer of the access node. The first data packet can be transmitted from the access node to a wireless device at the first transmission time and the access node can receive a retransmission request to retransmit the first data packet. The access node can determine an anticipated packet retransmission time based on when the access node received the request to retransmit the first data packet. The access node can retransmit the first data packet to the wireless device based on the anticipated packet retransmission time.

Abstract: First data packets for a wireless device are received from a data source at a network element, and are encoded into at least one second data packet using a data redundancy factor, where the at least one second data packet comprising at least two of the first data packets. The at least one second data packet is provided to an access node and is sent from the access node to the wireless device over a first frequency band. A round trip time of at least one of the first data packets is determined at the data source, and further a frequency band load of the first frequency band is determined. A handover is performed of the wireless device from the first frequency band to a second frequency band based on the round trip time and the frequency band load of the first frequency band.

Abstract: In operation, it is determined that a wireless device is in communication with a first access node using a first frequency band, and that a first coverage area of the first access node includes at least a portion of a second coverage area of a second access node. A coverage proportion of the first coverage area which includes the portion of the second coverage area of the second access node is calculated, and based on the coverage proportion a scan interval is determined. In addition, based on the determined scan interval and an application requirement of an application running on the wireless device, a signal level criteria is determined. When a signal level of the first frequency band meets the signal level criteria the wireless device is instructed to scan for a second frequency band of the second access node using the scan interval.

Abstract: Multiple network resources are considered when distributing network load among access nodes. For example, traffic load, user load, and bearer load may all be considered in the decision to move a wireless device from one access node to another. An N-dimensional load vector is calculated where each of the N dimensions is associated with a network resource utilization factor. A load vector is calculated for each of the access nodes being considered for load balancing. The load vectors for access nodes under consideration for load balancing are subtracted to create a difference vector. When the magnitude of the difference vector is greater than a threshold, the communication system balances the load between the two access nodes.
