| Automated control of simulcast ratios based on network traffic data provides efficient network capacity management. In one aspect, a remote switching matrix can be utilized at a venue to couple remote transceiver units (RTUs) with different antenna ports, for example, of one or more multi-beam antennas deployed at the venue. A simulcast ratio that can be utilized to support traffic demand at the venue can be determined and implemented by creating dynamic connections between the RTUs and the antenna ports. In one aspect, the simulcast ratio can be modified based on changes in network traffic at the venue that are monitored via self-organizing network devices. In addition, one or more antenna beams of the multi-beam antennas are remotely steered or rotated based on a location of the traffic. | ||||||

| 86 | METHOD AND APPARATUS FOR CALCULATING PAGING OCCASION UNDER EXTENDED PAGING CYCLE | US14876029 | 2015-10-06 | US20160029434A1 | 2016-01-28 | Tao QIU; Ningjuan CHANG; Haibo XU |
| Provided are a method and apparatus for calculating a paging occasion under an extended paging cycle. The method includes: calculating a frame number (SFN) where a paging message occurs by user equipment (UE) by using a formula SFN mod T=(T div N)*(UE_IDextended mod N); calculating a subframe number (i_s) where the paging message occurs by the UE by using a formula i_s=floor (UE_IDextended/N)mod Ns; and determining by the UE a paging occasion of the UE under an extended paging cycle by using the frame number and the subframe number where the paging message occurs; where, T is a paging cycle of the UE, which is equal to a specific discontinuous reception (DRX) value of the UE; UE_IDextended=IMSI mod (1024·2n), UE_IDextended being an identity index of the UE, IMSI is an international mobile subscriber identity of the UE, and n is the number of bits of an extended SFN; N=min(T,nB); Ns=max(1,nB/T); and nB∈{4T,2T,T,T/2,T/4,T/8,T/16,T/32}. | ||||||
| 87 | Method and Device of Communicating Paging Area Information | US14240676 | 2012-07-26 | US20150296088A1 | 2015-10-15 | Huiying Zhang; Ying Zhang |
| Examples of the present disclosure provide a method and a device for communicating paging area information. A radio access network (RAN) side device can determine a smaller area for group paging by using information of a group paging area provided by a services capability server (SCS) and cell coverage information. Therefore, when users are managed in groups, paging areas determined can be more accurate, and paging efficiency can be increased, waste of resources resulted from performing group paging in a too-large paging area can be avoided. The mechanism can prevent random access of a large number of users who have received the group paging from overloading the RAN and from impacting conventional human-to-human (H2H) users. | ||||||

| Systems and methods are described that mitigating coverage gaps near region boundaries using a plurality of multi-sector broadcast (MSBC) paging channels in wireless networking environments. One or more MSBC paging channels can be assigned unique time slots, such that although the channels can be identical, they are disjointed in time. Accordingly, such channels and/or dynamically generated paging zones associated therewith can be overlapped in areas where wireless device density is high and requires substantial paging capacity. Additionally, a single paging channel can be employed in multiple instances in a paging region without overlap to mitigate inter-channel interference. | ||||||

| 99 | Reducing signaling traffic with multicasting in a wireless communication network | US09515071 | 2000-02-28 | US06738639B1 | 2004-05-18 | Jean-Francois Gosselin |
| Signaling traffic communicated from a mobile switching center to a plurality of base stations is reduced by associating the plurality of base stations to form one or more multicast groups and assigning a multicast group address to each multicast group for use in multicast communications to the base stations within each multicast group. A network interface associated with each base station is configured to filter signaling traffic for multicast messages addressed to the multicast group to which the base station belongs. If the mobile switching center and the base stations are located on different subnetworks, multicast-enabled routers and/or filter switches are also configured to only route multicast messages over communication links that connect a corresponding multicast group member. The mobile switching center may then communicate a single multicast message to all base stations within a multicast group by using the multicast group's corresponding multicast group address. | ||||||
