Methods and systems for X2 link management in wireless communication networks

#This U.S. patent application claims priority under 35 U.S.C. §119 to India Application No. 4343/CHE/2015, filed Aug. 19, 2015. The entire contents of the aforementioned application are incorporated herein by reference.

#This disclosure relates generally to wireless communication networks, and more particularly to methods and systems for X2 link management in wireless communication networks.

#In Long Term Evolution (LTE) networks, automatic optimization of the wireless networks to reduce operating cost is comparatively complex when compared to other wireless networks. The complexity is because of requirement of multiple network and geographical parameters. Initially, the primary focus in implementation of LTE networks was on the radio coverage. However, with the increase in the number of subscriber and corresponding increase in demand of services, for example, Multimedia Online Gaming (MMOG), Mobile TV, Web 2.0, High Definition video streaming, Live meeting, increasing capacity of the LTE network to the expected levels without compromising the quality of service has become a challenge.

#The accompanying drawings, which are incorporated in and constitute a part of this disclosure, Illustrate exemplary embodiments and, together with the description, serve to explain the disclosed principles.

#FIG. 1 illustrates an exemplary wireless communication network in which various embodiments may function.

#FIG. 2 is a block diagram illustrating communication of various components of a control application in a Base Station (BS), in accordance with an embodiment.

#Exemplary embodiments are described with reference to the accompanying drawings. Wherever convenient, the same reference numbers are used throughout the drawings to refer to the same or like parts. While examples and features of disclosed principles are described herein, modifications, adaptations, and other implementations are possible without departing from the spirit and scope of the disclosed embodiments. It is intended that the following detailed description be considered as exemplary only, with the true scope and spirit being indicated by the following claims.

#Additional illustrative embodiments are listed below. In one embodiment, an exemplary wireless communication network 100 in which various embodiments may function is illustrated in FIG. 1. Wireless communication network 100 is a Long Term Evolution (LTE) network that includes an Evolved Node Base station (eNB) 102 and an eNB 104. Wireless communication network 100 may have more than two eNBs, such that one of the eNB acts as a Serving Base Station (SBS) and other eNBs act as Neighboring Base Stations (NBSs). For example, the SBS may have six associated NBSs. The eNB 102 has a coverage area 106 and communicates wirelessly with User Equipment (UE) 108, a UE 110, and a UE 112 within coverage area 106. The eNB 104 has a coverage area 114 and communicates wirelessly with UE 116, 118, and 120 within coverage area 114. Examples of a UE may include but are not limited to a cell phone, a smart phone, a tablet, a phablet, and a laptop. The eNB 102 and the eNB 104 form the evolved UMTS Terrestrial Radio Access Network (E-UTRAN) for wireless communication network 100.

#The eNB 102 wirelessly communicates with a Mobility Management Entity (MME) 122 and the eNB 104 wirelessly communicates with a MME 124 using respective S1 interfaces. Each of MME 122 and MME 124 may be replaced by a Serving Gateway (S-GW). Each of MME 122 and MME 124 further communicate with a Packet Data Network Gateway (PDN-GW) 126 through respective S5 interfaces. PDN-GW 126 further connects wireless communication network 100 with Internet 128 through an SGi link.
