Device, system and method of cell specific probability load balancing

#Embodiments pertain to radio access networks. Some embodiments relate to load balancing in cellular networks, including Third Generation Partnership Project Long Term Evolution (3GPP LTE) networks and LTE advanced (LTE-A) networks as well as 4th generation (4G) networks and 5th generation (5G) networks.

#The use of personal communication devices has increased astronomically over the last several decades. The penetration of mobile devices in modern society has continued to drive demand for a wide variety of networked devices in a number of disparate environments. The sheer number of user equipment (UE) using Third Generation Partnership Project Long Term Evolution (3GPP LTE) and LTE advanced (LTE-A) systems may generate issues related to loading of cells to which the UEs are attached. These issues may be exacerbated as the UEs move frequently at high rates of speed in relation to the coverage area of the cell or when the UEs change mode en masse. Accordingly, it would be desirable to provide improved load sharing of UEs.

#In the figures, which are not necessarily drawn to scale, like numerals may describe similar components in different views. Like numerals having different letter suffixes may represent different instances of similar components. The figures illustrate generally, by way of example, but not by way of limitation, various embodiments discussed in the present document.

#FIG. 1 is a functional diagram of a 3GPP wireless network in accordance with some embodiments.

#FIG. 2 is a block diagram of a 3GPP wireless device in accordance with some embodiments.

#The following description and the drawings sufficiently illustrate specific embodiments to enable those skilled in the art to practice them. Other embodiments may incorporate structural, logical, electrical, process, and other changes. Portions and features of some embodiments may be included in, or substituted for, those of other embodiments. Embodiments set forth in the claims encompass all available equivalents of those claims.

#FIG. 1 is a functional diagram of a wireless network in accordance with some embodiments. The network may be a 3GPP network, although the scope of the embodiments is not limited in this respect. As those skilled in the art will readily appreciate, various aspects described herein may be extended to other telecommunication systems, network architectures and communication standards. By way of example only, various aspects may be extended to other Universal Mobile Telecommunications System (UMTS) systems such as Time Division Synchronous Code Division Multiple Access (TD-SCDMA), High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), High Speed Packet Access Plus (HSPA+) and Time-Division CDMA (TD-CDMA). Various aspects may also be extended to systems employing Long Term Evolution (LTE) (in FDD, TDD, or both modes), LTE-Advanced (LTE-A) (in FDD, TDD, or both modes), CDMA2000, Evolution-Data Optimized (EV-DO), Ultra Mobile Broadband (UMB), Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX®), IEEE 802.20, Ultra-Wideband (UWB), Bluetooth, and/or other suitable systems. The actual telecommunication standard, network architecture, and/or communication standard employed will depend on the specific application and the overall design constraints imposed on the system. The network may comprise a radio access network (RAN) (e.g., as depicted, the E-UTRAN or evolved universal terrestrial radio access network) 100 and the core network 120 (e.g., shown as an evolved packet core (EPC)) coupled together through an S1 interface 115. For convenience and brevity sake, only a portion of the core network 120, as well as the RAN 100, is shown.

#The core network 120 includes mobility management entity (MME) 122, serving gateway (serving GW) 124, and packet data network gateway (PDN GW) 126. The RAN 100 includes eNBs 104 (which may operate as base stations) for communicating with UE 102. The eNBs 104 may include macro eNBs and low power (LP) eNBs.
