Description
Technical field
The present invention relates to the Long-distance Control and/or the monitoring of radio communication device.The present invention is applicable to but is not limited to purpose use short data message for this reason.
Background technology
For example the wireless communication system of cell phone or PMR private mobile radio communication system provides the radio telecommunication link usually, described radio telecommunication link will be set between a plurality of basic transceiver stations (BTS) and a plurality of subscriber's parts, and described subscriber's parts often are called as mobile radio station (MSc) or portable terminal (MT) or mobile unit (ME).In this manual, term mobile radio station (MS)/portable terminal (MT) and mobile device (ME) use interchangeably.
The method that is used for the while communication information exists, and wherein the communication resource in the communication system is shared by a plurality of users.This method is called the multiple access technology.There is multiple multiple access technology, for example frequency division multiple access (FDMA), time division multiple access (TDMS) and code division multiple access (CDMA), the limited whereby communication resource is divided into a plurality of physical parameters.
In this multiple access technology, be provided with different duplex (two-way communication) path.This path can be set up according to Frequency Division Duplexing (FDD) (FDD) structure, and frequency is specifically designed to uplink communication whereby, that is, to its serving BTS, and second frequency is specifically designed to downlink communication from MS, that is, from serving BTS to one or more MS.As selection, described path can also be provided with according to time division duplex (TDD) structure, and section is specifically designed to uplink communication the very first time whereby, and second time period was specifically designed to downlink communication.
Example based on the wireless communication system of zone/cell is face of land trunked radio (TErrestrial Trunked RAdio, TETRA) system, as ETSI (European Telecommunications Standards Institute, ETST) defined like that.TETRA equipment mainly be devoted to emergency service, provide as TETRA and dispatch and control operation.Each mobile radio station (MS) can send and receive control, voice-and-data information.Exchange of system infrastructure general reference and fundamentals of management structure (SwMI) in the TETRA system, except that described wireless (moving) communication component, it comprises all system elements basically.This comprises via base station controller (BSC) and mobile switching centre (MSC) and conventional Public Switched Telephone Network connection basis transceiver station (BTS).
In the field of the invention, well-knownly be, can develop multiple radio application, so make the foundation structure of radio system to come to send radio application and configuration parameter according to aerial (OTA) mode to a plurality of wireless subscriber parts.
Virtual network operator or actual third party software supplier can download (perhaps upgrading) related software and/or operating parameter to a plurality of (a perhaps group of planes) wireless subscriber parts, recall to factory and come reprogramming and need not a wireless subscriber parts.
Can also be by the programmer physical connection be carried out configuration and reprogramming to wireless device.Based on the TETRA wireless device, can use AT and TNP1 interface to realize configuration and control.The GSM phone also has the AT command interface, via described AT command interface, can realize radio control.Then, connect, be coupling in together such as the programming tool and the ME of laptop computer (being designated hereinafter simply as testing equipment (TE)), so that use the AT interface to simplify reprogramming, control and the configuration of ME by using therebetween hard wire.
Fig. 1 shows to illustrate and is used to use hard wire to connect 122 to come the simplified block diagram 100 of the first known mechanism of outer monitoring or programming ME 140.This mechanism that is used for externally programming or monitors the ME operation is applicable to TETRAMT or GSM phone.TE 110 connects 122 via first hard wire and is coupled to MT140, uses AT to order to simplify the programming of MT140 thus.
Described TE 110 comprises TE control application block, and it is used for monitoring and the described MT140 of control.Described TE control AT order is routed to described MT140 via the rs-232 standard interface.Described MT 140 receives the AT order via its rs-232 standard interface 152, and comes route SDS-AT message via its ' AT ' function 148, thus the SDS of described AT order (being used for configuration and outer monitoring) with message is partly separated.Subsequently, the SDS of described message part is routed to SDS application 142 via relay function 146.
In the field of the invention, the second hard wire connection mechanism is known, shown in the simplified block diagram of Fig. 2.The second hard wire connection mechanism is used TETRA procotol (TNP1) communication link between TE 220 and MT 260, so that simplify outer monitoring or the control of MT 260.
Described TNP1 mechanism uses known Internet protocol (IP) to finish external control or the monitoring of MT260.TE 220 comprises that TNP1 uses 222, and it provides software TNP1 code via User Datagram Protoco (UDP) (UDP) function 224, IP format function 226 and IP relaying 228 to PPP(Point-to-Point Protocol) function 230.Then, described TNP1 code is written among the MT according to the IP formatted message via hard wire link 232.
Described MT260 receives the formative TNP1 code of IP in its PPP function 272.Then, described TNP1 code is routed to TNP1 relay application 264.Employed IP address is the special IP address of being used by all MT, as defined in the TETRA standard.The IP datagram of issuing other IP addresses is via being sent to SwMI in the air.As everyone knows, in described MT, can exist one or more IP to use.Wireless application protocol (wap) is exactly this application.The message that comes from the WAP application is via being routed in the air.Depend on that the IP port numbers that is used for described message, the message that routes to the MT internal application are not routed to outside TE application, but are routed to inner WAP application.
Configuration shown in Fig. 2 allows the hard wire TE220 physical connection 232 to MT 260 such as laptop computer, so that configuration and monitoring MT 260.Yet, to use and the same method of described SDS-AT mechanism, described TNP1-IP mechanism requires to be connected with the physical hard-wired of MT 260.
Not in configuration of OTA shown in any chart and control.It should be noted that TETRAOTA configuration and the control messages use agreement of design respectively, it is different from SDS and IP.
As everyone knows, described TNP1 mechanism can be programmed or the MT of the single hard wire of Long-distance Control.This is the standard TETRA IP connectivity mechanism via described TNP1 PEI interface.
As indicating in advance, have only an IP address to be assigned to remote programmable or Long-distance Control function, and all be the same all MT in the TETRA system of this IP address.Therefore, for IP-based OTA programming structure, described MT 260 is assigned with the IP address that comes from SwMI 280.The WAP that described unique address makes IP datagram 282 can be sent to MT from SwMI 280 uses 262 or be sent to applications 222 on the TE 220.
Equally, for the inside WAP application 262 of MT, perhaps the outside TNP1 for TE uses 222, can be sent to SwMI 280 to IP datagram.These message are sent out via layer 2 to layer 1 transfer function 276,286 and subnet subordinate convergence protocol (SNDCP) function 274,284 between SwMI 280 and MT 260, as shown in the figure.Control messages between TE 220 and the MT 260 uses special IP address (standardized according to the TETRA standard) to be routed to MT 260.
Above-mentioned two (TNP1 or SDS-AT) mechanism any one in, as everyone knows, TE 110,220 can be configured to comprise ' virtual ' Long-distance Control stem of the wireless device in the overlapping top, so that allow MT140, a plurality of attribute of performance of 260 by outer monitoring (using local hard wire to connect).By this way, TE 110,220 can collect radio information, such as field strength at receiver, battery charge, error rate (BER) or the like.
According to the TETRA standard, except that aforesaid alternative hard wire, specific OTA programming and configuration mechanism have been described, these mechanism are used for simplification a plurality of application are downloaded to MT.Yet each during these are used all is independently to use, and utilizes himself specific mechanism to be downloaded to MT, and reconstruct MT operation.Thus, do not have general mechanism to reconfigure MT, so make each the new application that is written into to reuse standard interface or the previous programming function of using.
Yet though described MT can allow TNP code outside, that local application software is moved to be able to local control by exploitation, this known systems has following defective, requires the physical connection of programmer (TE) and MT that is:.This for most of actual conditions of expectation Long-distance Control/monitoring/programming, be very heavy, non-dynamically and limited by infeasibility.
In the TETRA field, remote control application software has been developed so that the described wireless device of Long-distance Control in all cases.The example of this Long-distance Control comprises:
(i) dynamic group number assignment (DGNA), it allows wireless device to be attached to some group; Perhaps
The (ii) assistant service of ambience listening (Supplementary Service of AmbienceListening, SS-AL), it is used for set up calling out from control desk so as under mobile subscriber's condition of unknown, control desk can monitor the microphone of MT.
The technology (such as DGNA and SS-AL) that is used to carry out the TETRAMT Long-distance Control and develops is designed to himself agreement of each application requirements.This makes the use of remote application Control Software have no attraction, and carries out very complicated.
Thus, need a kind of improvement and mechanism that simplify, so that do not requiring that support software comprises under the situation of himself agreement, is used for Long-distance Control/monitoring communications device.
