Abstract: A more efficient network can be achieved using channel allocation strategies within a wireless network. A network device can receive several data points from a mobile device including resource request data, access condition data, and location data. Once the network device has received the aforementioned data points, the network device can identify channels that are conducive to a heightened quality of service for a resource being requested based on a signal attenuation associated with the channel. The network device can then facilitate a channel selection in response to an assessment of the data points and identifying a channel for the resource.

Abstract: Traffic associated with user equipment that are served by a first radio access network is steered to a second radio access network based on a rate of congestion criterion. Network load is monitored by an access point to determine rate of congestion data associated with the access point. As an example, the rate of congestion represents a change in network load of the access point over a defined time period. The rate of congestion data is then transmitted to one or more neighboring access points that can utilize the rate of congestion data to facilitate traffic steering, load balancing, and/or neighbor relationship management.

Abstract: A system that incorporates the subject disclosure may include, for example, monitoring a speed and an acceleration of a mobile communication device in a serving cell of a wireless network where the mobile communication device has a radio resource control connection with the wireless network, and selecting a first mobility speed group from among a plurality of mobility speed groups based on the speed and the acceleration of the mobile communication device, where handover parameter values are assigned to each speed group of the plurality of mobility speed groups, and where the handover parameters and their associated values are utilized for a handover by the wireless network from the serving cell to a target cell. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, detecting a triggering event based on a monitoring of utilization of a target cell within a cellular network system. A configuration policy including a handover configuration parameter set is determined, responsive to the triggering event. A target cell of a plurality of neighboring cells of the source cell is identified and a handover procedure of a user equipment from the source cell to the target cell is configured based on the handover configuration parameter set. The source cell provides the handover configuration parameter set to the user equipment connected to the source cell. The user equipment, while connected to the source cell, performs handover measurements from the source cell to the target cell based on the handover configuration parameter set, and a handover of the user equipment from the source cell to the target cell is based on the handover measurements. Other embodiments are disclosed.

Abstract: Traffic associated with user equipment that are served by a first radio access network is steered to a second radio access network based on a cell user occupancy criterion. Cell user occupancy data that represents a maximum number of devices served by an access point is determined based on a type of the access point (e.g., macro access point, femto access point, WiFi access point, etc.). Further, based on the cell user occupancy data, a normalized index value is generated that is relative to different cell types/capacities. The cell user occupancy data is then transmitted to one or more neighboring access points that can utilize the cell user occupancy data to facilitate traffic steering, load balancing, and/or neighbor relationship management.

Abstract: Adjusting RAN performance by adapting cell coverage area can help optimize a wireless communications network. RAN topology can be adapted based on analysis of real-time load conditions of RAN base stations. Analysis of the load conditions of RAN base stations can be performed in a core-network of a wireless carrier rather than distributing the analysis to RAN-side elements. Analysis can be based on receiving real-time load information relating to key performance indicators such as X2 load, S1 load, instant outbound handover count, instant inbound handover count, etc. Further, analysis can include the application of predetermined rules relating to preferential performance of the base stations. This can facilitate ranking neighboring base stations, adding new base stations, deleting base stations, black/white listing base stations, etc., in neighbor relations data structures, such as automatic neighbor relations structures for self-organizing networks, e.g., eNodeBs in LTE networks.
Abstract translation: 通过调整小区覆盖区域来调整RAN性能可以帮助优化无线通信网络。 RAN拓扑可以基于RAN基站实时负载情况的分析进行调整。 RAN基站的负载状况分析可以在无线载波的核心网中进行，而不是将分析分发到RAN侧的元素。 分析可以基于接收与X2负载，S1负载，即时出站切换计数，即时入站切换计数等关键性能指标相关的实时负载信息。此外，分析可以包括应用与优惠性能相关的预定规则 的基站。 这可以促进在相邻关系数据结构中的相邻基站的排序，添加新的基站，删除基站，黑/白列表基站等，例如用于自组织网络的自动相邻关系结构，例如LTE中的eNodeB 网络。

Abstract: Traffic associated with user equipment that are coupled to a first radio access network is steered to a second radio access network based on an adaptable signal strength criterion. The signal strength criterion is related to real-time network load conditions of the first radio access network and can be broadcasted from a serving access point to the user equipment. Moreover, the signal strength criterion facilitates steering, to the second radio network, traffic associated with user equipment that are located closer to a cell edge of the first radio access network before steering traffic associated with user equipment are located further away from the cell edge. In addition, based on the network congestion within the first radio access network, the signal strength criterion is modified to adjust the number of user equipment that are steered to the second radio network.
