lte failover

Since 2008, Red Bend has partnered with Alcatel-Lucent to help device manufacturers and mobile network operators deliver mobile devices and services to the market faster and more easily. Using the OMA DM client on 4G LTE devices, device manufacturers can ensure that their devices are seamlessly compatible with the operator's Custom open Mobile Alliance Device Management (OMA DM) specification. "Industry standards like OMA DM enable mobile operators to

points of the sub-carrier overlay becomes SC-FDMA symbol, because the modulation is done in the time domain, so the uplink of a UE data can be regarded as a single carrier,So called SC-FDMA. A SC-FDMA symbol corresponds to the 12*NRB sub-carrier, and a time slot consists of 7 SC-FDMA symbols.4. For example, this re, which is assumed to be re (2,3), represents the third Sc-fmda symbolic symbol of the 2nd sub-carrier on the time domain. What this symbol is. is a waveform of physical space transfe

Summary: Core platform of 3GPP, http://www.3gpp.org/ftp/Specs/html-info/23228.htm First released by 3GPP Release 5, in order to enhance packet-switched domain (UMTS) in supporting IP multimedia services. Providing back compatibility to circuit-switched domains and functionality to other IMs domains. Nowadays, IMS provides access to Internet services (e.g. email, VoIP, video, etc) overdifferent networks (3g, cable TV, WLAN, XDSL, LTE, etc ). the

control information, but are only included in RRC when RRC messages are transmitted, RRC is a carrier. Once the security mode is activated, all RRC messages (including some NAS or 3GPP messages) of srb1 and srb2 are protected and encrypted through PDCP, NAS only protects and encrypts the integrity of NAS messages. In other words, layer-2 encryption and Protection of LTE: NAS only performs control signaling encryption, while PDCP performs both contr

default CSS style should be in the first line of the HTML document, and all content judged by the conditional comment must be behind the default style.For example, the following code, in IE, the execution of the display as red, and in non-IE browser display as black. If the conditional annotation is judged on the first line, it cannot be implemented. This example can explain the compatibility problem between IE and non-IE browser.At the same time, someone will try to use Normal is the default s

IE6 and the following versions are visibleIE7 and the following versions are visibleOnly IE6 versions are visibleIn addition to IE versionIE8 The following version is visibleIE7 and larger than IE7 versions are visibleUsage:(1)You can use the following code to detect the version of the current IE browser (note: No effect is visible in non IE browsers)If the current browser is IE, but the version is lower than IE5, how to do it, you can use LTE: Is the

It is necessary to note that the SQL Server failover cluster (SQL Server Failover Cluster) We build is an availability cluster, not a load-balanced cluster, which is designed to ensure continuity and availability of services, not to improve service performance.SQL Server always lacks its own products in a load-balanced cluster, which is provided by third-party manufacturers, but SQL Server

The first half of the task, there is a SQL Server Advanced topic, advance topics inside another important is about the cluster. Then there is the study.SQL Server cluster, the English full name is called Failover clustering, belongs to the category of high availability. Simply put, the role is to ensure that 7 X 24 hours of continuous service delivery, in a timely manner there are individual server downtime, the other servers will be seamlessly on the

diagram installation, establishment of a Windows Server 2012 failover Cluster Introduction: This article provides a detailed picture of how to install, verify, establish, configure, and test failover clusters in Windows Server 2012. Key words: Windows Server 2012 Failover Clustering In this section, which focuses on the Windows Server 2012

Before you build a cluster in the Windows Server R2 DataCenter environment, you first have to failover the cluster to the Windows Server (Windows Server Failover CLuster, referred to as WSFC) has a basic understanding. WSFC must be deployed in a domain-managed environment, consisting of multiple servers, each of which is called a node, and the Windows Server Failover
