Embodiment
Relevant detailed description of the present invention and technology contents, existing as follows with regard to accompanying drawings:
At first consult Fig. 1, Fig. 1 is the structural representation of a cordless communication network.The network element of a common radio communication cellular network is divided into the plurality of paging district physically, the specific paging zone of each mobile phone standby at any time under a certain base station (CS) and this base station.When mobile phone moved, it is less relatively that standby base station changes frequent and current paging zone variation, and therefore, network does not write down the standby base station of mobile phone, and writes down the current affiliated paging zone of mobile phone.A typical paging zone as shown in Figure 1 comprises several base station controllers (CSC), as the CSC1 to CSCn among Fig. 1.A base station controller comprises several base stations, the CS1 to CSn that connects respectively as each base station controller among Fig. 1.(it is called to make a general reference all when certain mobile phone called party, comprise voice, note is submitted, dont answer incoming call or the like), at first be broadcast to this mobile phone paging zone affiliated base station controller and base station from the SETUP of gateway (article one message that makes a call also claims " foundations ") message, called to this mobile phone broadcasted in all base stations that belong to this paging zone then on Common Control Channel, after the called mobile phone response, signaling is transmitted in point-to-point mode between called mobile phone and network.
Because the signalling path bandwidth between gateway and the base station controller is 64Kbit/S at present, and only is 16Kbit/S between base station controller and the base station.When terminating traffic is high, the broadcasting of SETUP message has been taken most of bandwidth of signalling path, especially had long UUI (User-User Information, user-user information) and submit the professional SETUP that initiates for note and broadcast.
The present invention adopts short INFO to replace SETUP message and realizes above-mentioned broadcasting flow process.See also Fig. 2 and Fig. 3, Fig. 2 and Fig. 3 are respectively the structural representation of INFO and SETUP message.The information unit of INFO comprises protocol-identifier, call reference, type of message, escape, WLL Function Identification, called number.These information units are that 2 to 23 bytes may be than big except that called number, and other information units are all less.Therefore, the total length of INFO is no longer than 30 bytes.The information unit of SETUP message comprises protocol-identifier, call reference, type of message, bearing capacity, calling number, called number, UUI.Wherein, the length of bearing capacity, calling number, called number is all bigger, and especially UUI reaches 131 bytes.Therefore, the total length of SETUP message is the longest reaches 195 bytes.
Realize the broadcasting flow process in order to adopt short INFO to replace SETUP message, need carry out adaptive modification the paging of existing wireless communications network.See also Fig. 4, this is the flow chart of one embodiment of the present of invention.In this embodiment, the INFO that gateway will comprise called number is broadcast to several base station controllers of its subordinate, and base station controller is broadcast to several base stations of its subordinate with this INFO, and the base station is broadcast to user's addressing with this INFO; The called subscriber receives that this INFO sends a return information as the base station of addressing response to its place, this base station is sent to this return information the base station controller at its place, base station controller is sent to gateway with this return information, gateway by this return information the path of process send SETUP message to the called subscriber after setting up point-to-point communication.
In said process, gateway sends after the INFO, starts the T303 timer; Gateway stops the T303 timer after receiving fault message.The T303 timer is to be used for setting a period of time, if during this period of time gateway does not receive that any response message just stops this process automatically, causes network congestion to avoid gateway to wait as long for response.When gateway is received return information, stop the T303 timer and start another timer, promptly the T310 timer is the next step timing to begin.
Similarly, base station controller sends after the INFO, starts the T303 timer; Base station controller stops the T303 timer after receiving fault message.And base station controller then stops the T303 timer and starts the T310 timer when receiving the return information that the base station sends.
In order to enlarge range of application of the present invention, the present invention has also considered the compatibling problem with original flow process.Because the Call Reference Value of each calling is different, only need to check to have or not identical Call Reference Value just can know whether same call.Base station controller reads and preserves the call reference information in the INFO in one embodiment.Base station controller is received after the SETUP message that gateway sends by checking that whether consistent preserve in its Call Reference Value and the base station controller check whether this calling exists, if exist, illustrate that then gateway used technical scheme of the present invention and sent INFO, base station controller can search and send that SETUP message is called out relevant base station to this and the base station broadcast under it not; If there is no, illustrate that then gateway does not adopt technical scheme of the present invention to send INFO to this base station controller, then press general flow,, it is broadcast to the base station of all connections as the Q931 standard.Whether same base station also can be provided with SETUP message that this function checks that base station controller is sent and exist and make respective handling.
The present invention not only is applicable to the above network schemer of introducing, and for having multilayer message transferring device, cordless communication network pattern the present invention of each the corresponding some subordinates of higher level's transferring device transferring device is all applicable.Therefore the present invention can be expressed as: the message dispensing device will contain some transferring devices of the information broadcast of call subscriber ID to its subordinate, some transferring devices of its subordinate again respectively with this information broadcast to some transferring devices of next stage again, so until with this information broadcast to user side; Called subscriber's user side sends the transferring device of return information to its upper level after receiving this information, this transferring device is sent to this return information its higher level's transferring device again, so until return information being sent to the message dispensing device, the message dispensing device is set up point-to-point the connection according to the path that this return information transmitted with called subscriber's user side and is carried out communication.
Equally here also timer can be set, the message dispensing device starts its first timer after broadcasting the information that contains call subscriber ID.The message dispensing device stops its first timer after receiving information, and the information here comprises return information and fault message, and wherein the message dispensing device starts its second timer after receiving return information.
Check whether this calling exists receive the initial information beyond the information that contains call subscriber ID for each grade transferring device after, if exist, then this transferring device is sent to subordinate's transferring device or the user side that sends return information, and it is not broadcasted subordinate's transferring device or user side under it; If there is no, then it is broadcast to subordinate's transferring device of these all connections of transferring device.
In other embodiment, the message dispensing device be broadcast to its subordinate some transferring devices be the compression after initial information.The effect that reduces broadcast data stream be can play so too, just need compression and decompression device be added at message dispensing device and user side.Different is: check whether this callings exists after receiving initial information beyond the initial information after the compression for each grade transferring device, if existence then directly abandons this initial information; If there is no, then it is broadcast to subordinate's transferring device of these all connections of transferring device.
