Abstract
The invention relates to a procedure for ensuring emergency calls in a wireless local loop in which subscriber's stations (MS) are connected over a radio link via a base station (BS) to an access node (AN) and from the access node to a local exchange (LE) of a wired telephone network, in which procedure the authentication process carried out in conjunction with call setup comprises establishing whether the call is to be initiated with a normal call start message or with an emergency call start message that is allowed to cause forced disconnection of another ongoing call having a lower priority in a known manner. A call initiated with a normal call start message is assigned top priority and a definition is made to the effect that forced disconnection of the call is not allowed and that the call is not allowed to cause the disconnection of another call, and the dialling information of the call is compared with a set of predetermined emergency numbers, and if the call is addressed to a number other than a predetermined emergency number, then the priority level of the call is lowered and forced disconnection of the call is allowed.
Description
The process of guaranteeing urgent call in the wireless local loop that the present invention relates to define in claim 1 preorder.
In wireless local loop (WLL), terminal equipment is connected to access node (AN) or WLL controller by Radio Link.Access node can comprise multiplexer, crossbar switch and different transmission systems.The WLL system can be based on the technology of using in the mobile telephone system for example, for example GSM/DCS1800 technology (GSM, global system for mobile communications; DCS, digital cellular system).GSM is the pan-European digital mobile communication system by etsi standardization.DCS-1800 is the mobile communication system by etsi standardization, and it is intended to more effectively utilize macrocell based on the GSM standard, works in the 1800MHz frequency range.By a base station, terminal equipment can send to public telephone network through access node by this base station by the call signal that wireless channel sends between terminal equipment and the access node, and vice versa.Adopt the V5.2 agreement of for example following ETSI300 347-2 standard, access node or WLL controller can be connected to telephone exchange.
In this application, guarantee that urgent call means, when overload appears in the base station in wireless local loop, can guarantee the call setup that subscriber board is initiated, call out when discharging resource and be used for setting up of urgent call having to interrupt other simultaneously, avoid hindering in the same base station other ongoing urgent call from other subscriber board.
In the system that follows the mobile communication standard, for example in the gsm system, if the not enough situation of resource, beginning message with urgent call is the calling that the calling of beginning can force to discharge low priority.
When access node under normal load condition during call transmission, the system of control base station wireless resource does not also know which is ordinary call in the ongoing calling, which is urgent call.This is because have only from so-called nontransparent WLL subscriber board and mail to general emergency numbers, for example 112, urgent call just begin message (for example following " urgent call foundation " message of GSM standard) and take the lead with urgent call.Mail to the user ID unit, for example subscriber board with SIM card in the calling of emergency numbers of appointment then with the ordinary call start information, for example follow " call setup " message of GSM standard and take the lead, if there is available idle communication channel.Under the situation of so-called transparent WLL subscriber board, set up even the calling of mailing to emergency numbers is also set up process by ordinary call, and begin message with ordinary call and take the lead, because when dialing this number, set up the communication link of switch.
Therefore, problem is, work as overloaded base stations, (this calling begins message with urgent call and certain subscriber board in this base station radio local loop is initiated a urgent call, for example " urgent call foundation " take the lead), then can't carry out pressure release,, start although this calling is set up message (" call setup ") with ordinary call because will be interrupted so that other calling that urgent call is set up also may be a urgent call according to the urgent call resource of GSM standard.Also ongoing calling can't be handed over to other base station, because do not allow user mobility in the WLL access node.
In initial gsm system, this problem can't occur, and always begins message (" urgent call foundation " message) with urgent call and takes the lead because mail to the urgent call of general emergency numbers.If this sub-district is fully loaded, two kinds of modes of handling this situation are then arranged: the forced interruption (replacement) of forcing to be handed over to another sub-district or ongoing certain calling, because the resource management system of wireless network is always known ongoing urgent call, so this is feasible.
Under following situation, allow forced interruption and/or handover:
The calling (being urgent call in this case) of-wait communication channel has the right to interrupt certain ongoing calling,
Calling of set damage property indicating device (permission damage property) of-existence, and
-wait for that the priority of the calling of radio communication channel is 1.
The objective of the invention is to provide a kind of process, make it possible under the wireless local loop overload situations, guarantee the foundation of urgent call, prevent other ongoing urgent call of forced interruption simultaneously.
Another object of the present invention is to provide a kind of process, begin message initiated urgent call even make it possible to from ordinary call, discern or distinguish out with ordinary call, thereby which calling the wireless network management of system learns is urgent call, and which calling is can be interrupted to discharge the ordinary call of resource.
The feature of process of the present invention provides in claim 1.
In process of the present invention,
A) begin message initiated calling with ordinary call and be endowed limit priority, specify not allow this calling to be forced to interrupt and cause the interruption of another calling, and
B) relatively should call out number information and one group of predetermined emergency number of being dialled,, then reduce the priority of this calling, and allow forced interruption to call out if a number that is not included in this group predetermined emergency number is mail in this calling.
Based on the present invention, system can determine which ongoing calling is urgent call, and which is the ordinary call that can discharge under overload situations.
In a kind of embodiment of this process, the priority that reduces in the stage b) is at the radiolink of definition wireless local loop and the interface of the signaling between the cable telephone network, particularly be to upgrade on the so-called Abis interface, the information of the priority of relevant new reduction is sent to the resource management system of wireless network, thereby the latter knows when receiving urgent call under overload situations which begins message initiated calling with ordinary call and can be forced to interrupt.
In a kind of embodiment of this process, calling out beginning message is to follow the message of mobile communication standard.
In a kind of embodiment of this process, calling out beginning message is to follow the message of GSM standard.
In a kind of embodiment of this process, it is that " call setup " calls out beginning message that ordinary call begins message.
In a kind of embodiment of this process, it is that " urgent call foundation " calls out beginning message that the calling of urgent call begins message.
In a kind of embodiment of this process, the stage limit priority of assigning in a) is the priority 1 according to the GSM standard.
In a kind of embodiment of this process, the lowest priority of assigning in the stage b) is non-1 priority according to the GSM standard.
In a kind of embodiment of this process, the comparison in the stage b) is carried out in access node.
In a kind of embodiment of this process, predetermined emergency number is the user ID unit that is stored in subscriber board, for example emergency numbers in the SIM card.The user ID unit, for example predetermined emergency numbers also is defined in the parameter of this access node naturally in the SIM card, thereby can compare.
Referring to accompanying drawing, describe the present invention by several examples of the embodiment of the invention below, accompanying drawing has provided a kind of system diagram that can use process of the present invention.
The figure shows a kind of wireless local loop system WLL in the wireless local loop, wherein subscriber board MS is connected to access node AN by Radio Link through base station BS, and is connected to local switch LE the cable network from this access node.
In authentication process, composed with following parameter with common " call setup " message initiated all-calls from the WLL access node:
Limit priority 1
Call out and be not forced to interrupt (forbidding damage property)
Do not allow to call out the forced interruption that causes another calling.
Correspondingly, beginning the calling that message " urgent call foundation " starts with urgent call is composed with following parameter:
Limit priority 1
Call out and be not forced to interrupt (forbidding damage property)
Allow to call out the forced interruption that causes another ongoing low priority call.
Access node AN is established to the suitable connection of local switch LE according to the needs with " call setup " message initiated calling.If access node AN can dial the number to the user and make an explanation, then it is compared with predetermined emergency number.If certain other emergency numbers of appointment among general emergency numbers 112 or the SIM is mail in this calling, then during calling out, this time do not change the priority of this calling, in other words, keep its priority 1.
If mail to certain other emergency numbers that is not appointment among general emergency numbers 112 or the SIM with " call setup " message initiated calling, the processing of then relatively dialling in number will send data to wireless network along signaling link, indicate the priority of the reduction of this calling.The parameter of this calling is set, makes
The priority of this calling reduces (be not to certain 1 value)
Allow the damage property of this calling.
If the message of relevant reduction priority arrives the signaling process of Abis interface, then described signaling process is with himself data of the priority update that reduces, and new priority is notified to the wireless network resource management of this sub-district, signaling between the transmission path of aforementioned Abis interface definition wireless local loop and the cable telephone network.
Therefore, begin message if under possible overload situations, receive with urgent call, i.e. the message initiated calling of " urgent call foundation " calling beginning, then the resource management system of wireless network can start the forced call interruption.Wireless network resource management is known under emergency can interrupt for which calling.This process makes wireless network resource management can determine to discharge which calling under the overload situations and is set up so that possible urgent call connects.
The present invention is not limited to the foregoing description example, but can carry out many variations in the framework of the defined innovative idea of claims.
