| |
| − | '''HiPath Cordless IP''' V1 is the [[DECT]] over [[IP]] solution for pure IP platforms.
| |
| | | | |
| − | The radio technology used in the HiPath Cordless IP solution complies with the DECT (Digital Enhanced Cordless Telecommunications) standard. The HiPath Cordless IP solution now makes the DECT standard already established for mobile voice communications also available in Voice over IP infrastructures.
| |
| − |
| |
| − | The flexibility in number of users, user density, coverage, extensibility and the provision of comfort features with the up-to-date [[Gigaset professional]] handsets characterize the system architecture of HiPath Cordless IP. The connection to the Voice over IP infrastructure of [[HiPath OpenOffice ME]] and [[HiPath OpenOffice EE]] is made by means of the SIP protocol. This means that DECT radio cells are the perfect way to supplement SIP-capable Voice over IP systems as mobile communication solutions.
| |
| − |
| |
| − | == Key Features ==
| |
| − | The entire radio range managed by the system consists of DECT IP base stations that either together form a seamless network of overlapping and synchronous radio cells or individual islands of radio signals. The size of a radio cell depends on local conditions.
| |
| − |
| |
| − | DECT IP base stations support the seamless [[wpen:Handoff|handover]] of existing voice connections, in other words the changeover between the radio cell and a DECT handset during a call. In addition, the [[wpen:Roaming|roaming]] function is made available to mobile users, i.e. the change of radio system without an existing call.

| |
| − | The HiPath Cordless IP system solution consists of the following main components:
| |
| − | * Handsets: Gigaset professional DECT handset with [[PN-CAP]] functionality
| |
| − | * Base station: DECT IP base station with PN-CAP/ [[wpen:Generic access profile|GAP]] functionality for the supported Gigaset professional handsets and IP interface with the Ethernet network
| |
| − | * HiPath Cordless IP server software is the central software component for:
| |
| − | ** controlling the DECT IP base stations
| |
| − | ** implementing the SIP/[[RTP]] interfaces in the direction of HiPath OpenOffice
| |
| − | ** central administration and configuration of the entire HiPath Cordless IP solution
| |
| − | The HiPath Cordless IP server software can be activated on one of the DECT IP base stations. Nevertheless, this DECT IP base station allows making calls.

| − | == Overview ==
| |
| − |
| |
| − | This section gives you an overview over the most important features of HiPath Cordless IP V1.
| |
| − |
| |
| − | === DECT IP base station (BSIP1) ===
| |
| − |
| |
| − | [[Image:HiPath Cordless IP - DECT IP base station.jpg|right|120px]]
| |
| − | DECT IP base stations form a network of radio cells and conduct communications with the Gigaset professional handsets. Special antennae can be used for increased radio ranges. The DECT IP base stations can be fitted with an outdoor casing to protect against inclement weather.
| |
| − | DECT IP base stations have the complete software for DECT and IP functionality. This software does not need to be configured and administered locally on the DECT IP base stations; this can be conveniently implemented on a centralized basis by means of the HiPath Cordless IP server software.
| |
| − |
| |
| − | === HiPath Cordless IP Server SW ===
| |
| − |
| |
| − | [[Image:HiPath Cordless IP - Server SW.jpg|right|120px]]
| |
| − | The HiPath Cordless IP server software has several functions, only exists once in the system and can be activated on one of the DECT IP base stations.
| |
| − |
| |
| − | ==== '''Function: Router and protocol converter''' ====
| |
| − | HiPath Cordless IP server software is the interface between the IP DECT base stations on the one hand and HiPath OpenOffice on the other.
| |
| − | It has a router and protocol converter function whereby it controls the voice connections between HiPath OpenOffice and the relevant DECT IP base station and also converts these into a data format that can be used by the DECT base stations.
| |
| − | Only the HiPath Cordless IP server knows the DECT IP base stations with which the relevant handsets are associated; this is not apparent to HiPath OpenOffice. The HiPath Cordless IP server software is a Gateway User agent for HiPath OpenOffice which manages the configured handsets.
| |
| − | The HiPath Cordless IP server software is also used to register all handsets on HiPath OpenOffice; this software administers the login procedure and the active DECT handsets.
| |
| − |
| |
| − | ==== '''Function: Configuration and administration interface''' ====
| |
| − | All administration and configuration of DECT IP base stations and of the HiPath Cordless IP server software itself is executed by means of the web-based management of HiPath Cordless IP server software.
| |
| − |
| |
| − | ==== '''Function: Synchronization management''' ====
| |
| − | In DECT systems with a circuit-switched connection, e.g. HiPath Cordless Office systems, the synchronization information required to synchronize the base stations is derived from the U<sub>P0</sub> connection. This is because of the IP connection of the base station not possible in the case of the HiPath Cordless IP system.
| |
| − | However, accurate time synchronization between the DECT IP base stations is vital for a seamless call handover.
| |
| − | A seamless handover cluster is formed between synchronous DECT IP base stations; calls can only be handed over seamlessly in this cluster. More clusters of this type are possible for each HiPath OpenOffice, however these are not synchronized with each other. Seamless handover is not possible between different non-synchronous clusters.
| |
| − |
| |
| − | ''Synchronization via DECT to form this seamless handover cluster (synchronization via air)''<br />
| |
| − | In order to synchronize with another DECT IP base station via the DECT interface, a DECT IP base station must be within the overlap area of the radio cell that forms this DECT IP base station.
| |
| − | In addition, the DECT IP base station can be synchronized on other DECT IP base stations, which increases the availability of synchronicity in this cluster.
| |
| − | In the event that synchronicity is lost, this DECT IP base station no longer accepts calls. After all ongoing calls on the asynchronous DECT IP base station have been ended, an attempt is made to resynchronize this DECT IP base station. Only then can new calls be made on this DECT IP base station.

| |
| − | === Communication Interfaces ===
| |
| − |
| |
| − | [[Image:HiPath Cordless IP - Kommunikationsbeziehungen eng.jpg|right|320px]]
| |
| − | The following is an overview of the communication relationships used in the solution:<br />
| |
| − | ''DECT handset - user:'' Gigaset professional DECT handset, with alternative [[Headset]] oder [[Bluetooth]] headset<br />
| |
| − | ''DECT handset – DECT IP base station (BSIP1):'' A call can be handed over seamlessly between the DECT IP base stations.<br />
| |
| − | ''DECT IP base station (BSIP1) – DECT IP base station (BSIP1):'' Accurate time synchronization between the DECT IP base stations is vital for a seamless call handover.<br />
| |
| − | ''DECT IP base station (BSIP1) – HiPath Cordless IP server software:'' The DECT IP base stations all communicate with the HiPath Cordless IP server software; the voice and signaling data is transported in this connection. The connection protocol between the DECT IP base stations and the HiPath Cordless IP server software is system specific; it is IP-based and uses [[wpen:User Datagram Protocol| UDP]] packages in both directions.<br />
| |
| − | ''HiPath Cordless IP server software – HiPath OpenOffice:'' The SIP protocol between the HiPath Cordless IP server software and HiPath OpenOffice is standards-based.<br />
| |
| − | ''HiPath Cordless IP server software - time server:'' A time server is not absolutely necessary. The time information is used to display this when the Gigaset professional is idle and to file the caller list with correct data. HiPath OpenOffice can also be managed as a time server.<br />
| |

| |
| − | * outdoor casing available
| |
| − |
| |
| − | '''Network Requirements'''<br />
| |
| − | If Voice over IP is to be integrated in a network environment, it is necessary to create conditions so that the voice connections can be operated smoothly by means of IP networks. The IP network must meet the general requirements for a VoIP network in relation to delays, losses and guaranteed service quality features.
| |
| − |
| |
| − | In addition, the following special conditions must be met between the DECT IP base stations and the HiPath Cordless IP server software in the IP network:
| |
| − | * these must be part of the same Ethernet segment; neither layer 3 routing via an IP router or Network Address Translation ([[NAT]]) are supported
| |
| − | * at least 2 priority classes according to IEEE 802.1 p/q are required in the VoIP network in order to prioritize the voice data
| |
| − | * Use of 100 Mbps full duplex for all switched LAN ports
| |
| − |
| |
| − | Otherwise delays occur in the IP network, leading to synchronization and voice quality problems on the DECT handsets.
| |
| − |
| |
| − | '''System Configuration'''<br />
| |
| − | Because the HiPath Cordless IP Server SW has been activated on one of the DECT IP base station, the following system restrictions apply in the first step:
| |
| − | * up to 10 DECT IP base stations
| |
| − | * up to 10 parallel calls
| |
| − | These system restrictions relate to each group of synchronous DECT IP base stations in which a seamless handover is possible. Other larger scenarios are planned.
| |
| − |
| |
| − | '''Analysis of the Building/Campus (Site Survey)'''<br />
| |
| − | When the DECT network involves approximately 3 DECT IP base stations, a site survey is recommended. This is particularly the case if:
| |
| − | * several floors or buildings are to be covered with DECT
| |
| − | * the solution will have to coexist with other DECT installations
| |
| − | * other radio-intensive devices are operated in the environment.
