Definitions
- the present invention relates to a method and a system for position management of mobile stations in a cellular mobile telephone system.
- Position management requires signalling via radio, which consequently implies that a certain part of the total radio capacity in a cellular system is needed for this type of signalling, which here for the sake of convenience is called position signalling.
- position management In order to make most possible share of the limited radio capacity possible to use for voice respective data traffic, the position management must be optimized so that it takes a minimum of the available radio resource. The degree of difficulty of the optimizing problem is increased by the fact that the mobile stations are just, as the name indicates, mobile.
- the strategy for position management is to find a suitable compromise between signalling in uplink, i.e. from the mobile station to one in the mobile system permanent installed network of base stations, and signalling in downlink, i.e. from the network of base stations to a mobile station.
- Signalling in downlink is normally executed by searching, also called “paging”, whereby a signalling message is transmitted from the network, to search for a mobile station in a limited area, a so called “Routing Area” (RA) which consists of one or more cells.
- RA Radio Area
- Signalling in uplink is executed by a mobile station at intervals transmitting a message to the network, which by that can keep count of where the mobile station is at the moment. Updating of the position of the mobile station is made on one hand at change of cell, which is called “Cell Update” (CU), and on the other at change of Routing Area, which in its turn consequently is called “Routing Area Update” (RAU).
- CU Cell Update
- RAU Routing Area
- GPRS General Packet Radio Service
- the capacity and the radio resource is utilized in a comparatively cost efficient way. This is due to the fact that a given GPRS mobile station utilizes a radio channel only when there are data that shall be transmitted or received by this mobile station.
- GPRS there are specified three states of a mobile station. i.e. “Idle State”, “Ready State” and “Standby State”, at which there are different operations for position management at each of the different states.
- Idle State the mobile station is not connected to the network, and the network therefore has no information about the position of the mobile station.
- RAU Routing Area Update
- CU Cell Update
- a Cell Update When the mobile station is in Ready State and it changes cell, a Cell Update (CU) is executed if the cells belong to the same routing area. If the new cell which the mobile station enters into also belongs to a new routing area, a Cell Update (CU) is executed combined with a Route Area Update (RAU).
- RAU Route Area Update
- RAU Routing Area Update
- the signalling load which is to be referred to the position management depends on the size of the routing area, and the time which the time parameter indicates. Within known technology there has since a long time been attempts at minimizing this signalling load by means of optimization of the size of the routing area.
- An aim of the invention and the overall problem to be solved is to further minimize the signalling load which depends on he position management.
- One in this context new problem which is an aspect of said overall problem, is to determine a time parameter which at each state of the mobile station minimizes the position management depending signalling load.
- the invention is based on the understanding that the problem can be solved by setting the value of the time parameter in relation to the speed of a mobile through a cell network.
- the time parameter is, according to the invention, set at a comparatively high value. This results in that the mobile station will for a longer time be in the Ready State and no paging need to be executed, because the network knows exactly in which cell the mobile station is.
- the paging signalling i.e, the signalling in downlink, therefore is significantly reduced. Because the mobile station is stationary, or only moving slowly, no or very low frequent Cell Updates (CU) are needed, which consequently results in low signalling also in uplink.
- CU Cell Updates
- the time parameter is, according to the invention, set at a comparatively small value. This in its turn results in that the mobile station is in Ready State during a shorter time, and instead more rapidly changes into the Standby State. This also results in a lower number of Cell Updates (CU) and, when necessary, Routing Area Updates (RAU) are executed, which consequently results in reduced signalling in uplink.
- CU Cell Updates
- RAU Routing Area Updates
- the time parameter which controls the time during which a mobile station is in Ready State/Wait Mood being set adaptively depending on the present speed of a mobile station through a cell network.
- FIG. 1 illustrates a simplified state diagram for a mobile station in a GPRS-system
- FIG. 2 illustrates a sketch of the principle of a cellular mobile telephone system according to the invention
- FIGS. 3A , 3 B and 3 C illustrates the principle of a base station, respective a mobile station, according to the invention.
- One embodiment of the invention consists of a procedure to reduce the signalling load in a cellular mobile telephone system which supports packet switched services.
- One in the mobile telephone system included mobile station is switched between a first mode in a first state, here called Ready State, respective a second state, here called Standby State, depending on time parameter which indicates a time during which the mobile station shall remain in the first state in order to, after that, change to the second state.
- FIG. 1 shows a simplified state diagram for such a mobile station, which can take an “Idle State”, 2 , a “Ready State” 4 , and a “Standby State” 6 .
- the Ready State includes 2 modes, that is “Wait Mode” 3 , respective “Receive/Transfer”-mode 5 .
- the mobile station changes at a GPRS-connection 8 from the Idle State 2 , to the Ready State 4 , and at a GPRS-disconnection 10 from the Ready State 4 , back to the Idle State 2 .
- the mobile station is in Ready State/Wait Mode 4 / 3 during an adjustable time which is controlled by said time parameter, and changes state at a change 12 to the Standby State 6 at the expiration of the set time.
- the mobile station changes state in a change 14 to the Ready State 4 and Receive/Transfer Mode 5 .
- signalling are, in the different states, executed which can be related to determining of position of the mobile station.
- the time parameter should, to effect a minimization of this signalling load, have a comparatively big value when the mobile station is stationary or is moving slowly, and a comparatively small value when the mobile station is moving rapidly.
- an adaptive adjustment of the time parameter is attained by the value of the time parameter being set currently, depending on the actual speed of the mobile station through the cell network of the mobile telephone system.
- the value of the time parameter can be set or adapted for instance regularly, irregularly or in response to one in advance defined occurrence.
- the time parameter of the mobile station is given a predefined value at the entry of the mobile station into the mobile telephone system, and after that the time parameter is reduced at a cell update according to a predefined rule.
- This rule can, for instance, be so designed that the value of the time parameter is halved at a cell update, preferably at each such cell update. If the mobile station is moved at a high speed through the cell network, a lot of cell updates are executed, and by that a rapid reduction of the value of the time parameter. Consequently the time during which the mobile station is in the Ready State, and by that also the signalling load, is reduced.
- the time parameter of the mobile station is, as in the first embodiment, given a predefined value at the entry of the mobile station into the mobile telephone system.
- the speed of the mobile station through the cell network is estimated currently, and at cell update the estimated speed is reported to the network.
- the speed of the mobile station is adapted according to a predefined rule which may be the same rule as is used at the entry of the mobile station into the system.
- the time parameter can, for instance, be set according to a table in which different time parameters for different speed intervals are described. In the case that there are corresponding time parameters at the mobile station, respective the cell network, said time parameter at the mobile station and said corresponding time parameter at the cell network are changed essentially at the same time.
- Speed estimation can be performed in one in itself known way, for instance as is described in any of the publications: M. Andersin, “An Algorithm for Mobile Speed Estimation in Cellular Networks”, Technical Report, 5/0363-04/FCPA 109 0001, Telia Research, January 1997; A. Sampath and J. M. Holtzman; “Estimation of Maximum Doppler Frequency for Handoff Decisions”, Proceedings: IEEE 43rd Vehicular Technology Conference, VTC-93, pp.
- FIG. 2 illustrates the principle of a cellular mobile telephone system 18 which supports packet switched services.
- the system includes a network of cells 20 which are served by a base station 22 for each.
- One in the mobile telephone system included mobile station 24 is transferred through the cell network according to a speed vector 25 .
- the mobile station is switched between a first mode in a first state, here called Ready State, respective a second mode, here called Standby State, depending on a time parameter which indicates a time during which the mobile station shall remain in the first state in order to after that switch to the second state.
- a mobile telephone system and/or a mobile station according to the invention includes means 26 to currently set the size of the time parameter or value depending on the current speed of the mobile station through the cell network of the mobile telephone system.
- a base station 22 or in a mobile station 24 there are, for most of the means, cooperating and possibly communicating devices on the one hand in the base station, and on the other in the mobile station, and how these devices are allocated, depend on the selection of implementation.
- FIGS. 3A , 3 B, 3 C shown both a base station 22 and a mobile station 24 equipped with said means.
- FIG. 3A shows in principle a first embodiment of a base station 22 , respective a mobile station, which includes means 28 to allocate to the time parameter of the mobile station a predefined value at the entry of the mobile station into the mobile telephone system, and means 30 to, at a cell update reduce the value of the time parameter according to a predefined rule.
- the value of the time parameter can be halved at a cell uppdate, preferably, but not necessary, at each cell update.
- FIG. 3B illustrates a second embodiment including means 28 for allocating the time parameter of the mobile station a predefined value at the entry of the mobile station into the mobile telephone system, means 32 to currently estimate the speed of the mobile station through the cell network, means 34 to report an estimated speed to the network at cell update, and means 36 to adapt the value of the time parameter to the speed of the mobile station according to a predefined rule.
- FIG. 3C illustrates a third embodiment including means 38 to report an estimated speed of the mobile station at its entry into the mobile telephone system, means 40 to set the time parameter of the mobile station according to a pre-defined rule depending on the speed, means 32 to currently estimate the speed of the mobile station through the cell network, and means 34 to, at cell update, report the estimated speed to the network, and means 36 to adapt the value of the time parameter to the speed of the mobile station according to a predefined rule.
- the means 36 and 40 can be the same.
- the time parameter is set according to a table in which different time parameters for different time intervals are described. To the extent that said time parameter has a corresponding time parameter in the cell network, these are changed essentially at the same time.
