Abstract
The invention relates to an LDA (Location Dependent Addressing) method and system, and a service control network element. The service control network element is used for receiving a location-dependent call initiated by a user, storing a corresponding relationship between location information of the user and a dispatching management area as well as a corresponding relationship between the location information of the user and an administrator of the dispatching management area, confirming that the user is about to break away from the current dispatching management area and enters another dispatching management area according to the corresponding relationships, the location information and a running direction of the user, and connecting the call to an administrator of the another dispatching management area in advance, and enabling the user to communicate with the administrator of the another dispatching management area. According to the invention, the fast-moving location-dependent call initiated by the user can be connected to the administrator of the another dispatching management area in advance, so that the precision rate of call connection is improved, and the dropped call rate is reduced.
Description
Technical field
The present invention relates to communication technical field, refer in particular to a kind of method, system and service control network element of location addressing.
Background technology
Location dependent addressing (Location Dependent Addressing LDA) is the characteristic of railway mobile communications network, the calling that is used for specific function that will initiate by the mobile subscriber, be routed to one with the relevant destination address in the current present position of this user.For example train operator call manager person or Platform attendant, correct keeper or Platform attendant are confirmed by the residing at that time position of driver.Like " big triangle " communication in the train dispatch radio communication, the keeper that travelling carriage will be called out is depended on mobile subscriber's present located position.When train when the driver need call out current keeper in running, he does not also know keeper's telephone number, but he can use a short codes (as 1200) to the network-originated call request.This short codes of Network Recognition, and it is routed to correct keeper.
In railway, location-based addressing is mainly used in the solution mobile subscriber and calls out fixed-line subscriber.In the railways train operation commander, railroad suboffice has direct commander's power.Each railroad suboffice all has the dispatching office of oneself, and with its control centre as railroad suboffice institute administration railway.Keeper in the railroad suboffice dispatching office comprises driving keeper, electrical management person etc.Driving keeper's responsibility is extremely important, and function is complicated, and is directly related with train traffic control.According to the rate of traffic flow of circuit, every driving keeper administers the train dispatching section of certain-length, is positioned at all stations of this section and all trains of just exercising at this section all will be accepted its commander.All there is a person on duty at each station, is positioned at all trains of station scope and also will accepts its commander.Train will pass through some train dispatching sections and some stations when driving, and when the driver called out driving keeper or Platform attendant, he can only call out current affiliated TD article or Platform attendant.But the driver can't know the telephone number of current driving keeper or Platform attendant.The railway mobile communications network has adopted location-based addressing in order to address this problem.Travelling carriage adopts short code (1200) to call out the driving keeper, adopts short code (1800) to call out Platform attendant, makes things convenient for driver operation like this, need not remember the Mobile Directory Number of each driving keeper and Platform attendant.
The problem that prior art exists is: the modern railways technology rapid development, the speed of train is more and more faster, often reaches 300～500km/h.This just means, possibly work as a driver and just initiate a location-based calling searching keeper A, calls out also to set up and accomplishes, and train causes the call setup failure between the administrative area that has driven to the B keeper between A keeper's administrative area.
Summary of the invention
Main purpose of the present invention provides a kind of method of location addressing, can make the user of high-speed cruising in the calling of position, can this calling be routed to the regional keeper of next dispatching management smoothly from the current scheduling management area.
