Such distinguishing features could be, e.g., a unique code sequence in a CDMA-based communication system or a frequency band in a GSM-system.
  • Said resources can be illustrated by means of, e.g., standardised communication channels with certain characteristics that are allocated to . the system of a network operator .
  • critical resources can also be defined as, e.g., the allocated bandwidth and the time for which said bandwidth is allocated. Both parameters depend mainly on the type of communication and the requested service that is performed between two network clients.
  • the bandwidth demand for instance, is higher for a communication connection that is used for a video application compared to a connection that is applied for speech transmission.
  • Another influence on the resource need of a network unit results from the time that is actually used for data exchange via a communication connection, e.g. a permanent connection or packet-based connection.
  • the resource need will also depend on the fact whether certain service guarantees must be taken into account or whether the service is performed on a best-effort basis.
  • the network operator will operate the network preferably from one location.
  • the operator's access to the system is defined by some form of a general subscription agreement while the degree to which extend the network operator is allowed to use said system will be regulated by means of a licence agreement .
  • each unit provides one connection to an assigned superior unit on a hierarchically higher level, which functions as the controlling unit of said unit, and can provide connections to one or more dedicated subordinated units on a hierarchically lower level, which represent the controlled units of said unit.
  • This logical structure is then applied in, e.g., a communication system in order to allocate and distribute necessary resources, e.g. in form of standardised communication channels.
  • the method according to the present invention implies for each system unit the steps of determining the actual resource status and indicating said status to the superior unit on the next higher hierarchical level.
  • the superior unit is responsible for equalising between indicated resource excesses and deficits of said subordinated units.
  • the arrangement according to the present invention comprises correspondingly means for determining a resource status from indicated resource statuses of its subordinated units, means for indicating and weighting said status, and means for equalising between indicated resource deficits and excesses of said subordinated units.
  • the present invention provides a method and arrangement with an increased flexibility in allocating system resources granting access to the system facilities on a "per need"-basis.
  • the decentralised resource allocation provides a faster and more reliable system that is less affected with faults.

  • the method according to the present invention can be applied in any kind of hierarchical system 10 as presented in figure 1.
  • a system 10 is designed as a plurality of interconnected units 11,121-123,131-135 with well-defined functionalities that interact with each other.
  • figure 1 only describes the logical aspects of a system structure with regard to the distribution and allocation of system resources whereas the system can be structurised in another way with respect to communication aspects, e.g. information exchange or signalling.
  • Said figure shows only those units that perform the method according to the present invention while other units are omitted.
  • a unit in such a hierarchical system can be identified as U[j,i].
  • said system units are arranged such that a unit U[j,i], e.g.
  • the lower level is the level (L-j+1) directly below said first level.
  • the lowest hierarchical level contains units 131-135 without dedicated children and the highest level denotes the root unit 11 in such a hierarchical system.
  • the transfer request indication command 14 indicates resource status information of a system unit to its superior unit.
  • the transfer allocation command 15 allocates resources of a superior unit to one of its subordinated units.
  • the efficiency of such a system 10 could be characterised by means of its system capacity, which denotes, e.g., the amount of dedicated system actions that the system can perform. This capacity depends mainly on resources that are allocated to the system in order to perform such actions. In particular, both the total amount of allocated resources and the allocation of such resources to the various units will have an impact on the total system capacity.
  • the hierarchical system 10 as described above could be, e.g., a nation-wide telecommunication system or a certain area that is part of such a telecommunication system.
  • a possible measurement of the system capacity could be the maximum number of user equipments that can be served with a sufficient quality of service and system units could be identified, e.g., as radio base stations or radio network controllers.
  • Licence agreements can be based, e.g., on the number of available communication channels.

  • a unit U[j,i] In a first step, a unit U[j,i] must determine its actual resource status, block 23.
  • Said resource status includes information about the resources of the unit itself and information about the resource status that is indicated from possible subordinated units U[j-1, i**] that are connected to said unit U[j,i] in its function as a superior unit.
  • Each of said subordinated units contributes with either a deficit or an excess of resources such that the total resource status Rtot of the superior unit can be determined by means of the sum of resources of the superior unit itself and of its subordinated units:
  • the reported resource status of the subordinated units includes in its terms also the resource status of units on an even lower level that are connected as subordinated units directly or indirectly to the actual subordinated units U[j-1, i**] .

  • the unit U[j,i] indicates the determined total resource status to a unit on a hierarchically higher level. If said unit is a subordinated unit of a superior unit on a higher level in the hierarchical system, block 24 Yes, i.e. the unit is another system unit on a hierarchical level (L-j-1) with j ⁇ L, the resource status is indicated to this superior unit U[j+l,i*]. The indicated resource status will then be applied by the superior unit U[j+l,i*] to determine its total resource status as correspondingly described for U[j,i].
  • the resource status can be indicated to a supervising external unit, block 28.
  • an external supervising unit e.g., a network operator
  • a unit U[j,i] calculates in its function as a superior unit its total resource, status by help of the indicated resource statuses of its subordinated units U[j- 1, j**] and reports this status to its superior unit U[j+l,i*].
  • said total resource status gives no indications about the distribution of these resources amongst the subordinated units.
  • the other possibility is that some of the subordinated units have an excess of resources while others have a corresponding deficit of resources. Because these differences are not visible for a unit on a higher hierarchical level, it is the responsibility of the superior unit U[j,i] to initiate appropriate measures in order to equalise resource deficits and excesses between its subordinated units U[ -1, i**3 , block 26, such that, e.g., a deficit of resources in one of said subordinated units is, at least partly, compensated by an excess of resources in another subordinated unit.
  • said steps are performed on the next higher hierarchical level by means of incrementing the level index j, block 272, and resetting the index value i, block 22.
  • the timer index value n is incremented, block 29, which indicates that the method is repeated at a subsequent time Tn+i .
  • Figure 3 shows in greater detail the method steps that are performed in order to equalise excesses and deficits between subordinated units of a unit U[j,i] .
  • Said steps can be performed only if some of the subordinated units have reported a deficit of resources while other subordinated units have reported an excess of resources, block 261 Yes and block 263 Yes. If, however, none of the subordinated units have indicated an excess of resources, block 261 No, this can imply that all subordinated units are in a resource equilibrium or all indicating a resource deficit such that the superior unit only need to indicate that deficit but cannot perform any equalisation measures before it will have received the necessary resources .
  • the exceeding resources of the subordinated units can be allocated to the superior unit, block 262, in order to be available for a unit on a higher hierarchical level or in order to be allocated to subordinated units that indicate a resource deficit, block 264.
  • block 263 No no equalisation measures need to be performed.
  • subordinated units that indicate a resource deficit block 263 Yes
  • there are several alternatives to perform a resource equalisation The preferred alternative is to distribute the exceeding resources subsequently to the subordinated unit that has the largest resource deficit at the moment, block 264. By this means resources are quickly distributed to those units that probably have the largest traffic density at the moment.
  • Another alternative would be to distribute said exceeding resources subsequently to the subordinated unit that momentarily has the lowest resource deficit. By this means the total number of units with sufficient resources could be maximised. However, it is notwithstanding possible to apply any other ranking criterion for determining an order within which exceeding resources are allocated.
  • Figure 4 shows the signalling flow between system units that is performed by a unit U[j,i] 42 in connection with a transfer of resources that is performed by means of the above described steps of indicating the resource status to the superior unit U[j+l,i*] 41 on a higher level and equalising the reported resources amongst the subordinated units U[j-1, i**] 43 on a lower level.
  • Said transfer of resources is performed by help of two commands:
  • Subordinated units 43 report their excess or deficit of resources by means of a transfer request indication 44 to their respective superior unit 42. From this the unit 42 can determine its total resource status, which is reported to the superior unit 41 on the next higher level, by means of another transfer request indication 45.
  • the step of resource equalisation as described above is performed if some of the subordinated units 43 have reported a deficit of resources while other subordinated units 43 have reported an excess of resources.
  • a transfer allocation command 46 it is possible for the superior unit 42 to transfer exceeding resources from one subordinated unit to another subordinated unit that has indicated a deficit of resources.
  • a unit 42 must only be aware of the distribution of resource excesses and deficits amongst its direct subordinated units 43.
  • units 41 on a higher level need no information about that distribution but only about the total resource excess or deficit of the unit 42.
  • the transfer request indication 45 that has been sent to the superior unit 41 on a higher hierarchical level will result in the allocation of the required additional resources in connection with a transfer allocation command 47 from said superior unit 41.
  • the superior unit 42 can, by means of recurring transfer allocation commands 46, transfer the required amount of resources to those of its subordinated units that have indicated the corresponding resource deficit during the preceding time interval Tn.
  • a first strategy is to distribute exceeding resources that are already available for the superior unit 42 at once by means of said transfer allocation commands 46 while the remaining resources are distributed when said superior unit 42 has received these resources from its superior unit 41.
  • Another conceivable strategy could be that a superior unit 42 keeps the already available resources until it has received the remaining resources from its superior unit 41 and then distributing the resources to the appropriate subordinated units 43. This implies, with regard to figure 4, that the superior unit 42 waits for the transfer allocation command 47 from its superior unit 41 before performing the transfer allocation commands 46 towards its subordinated units 43.
  • the excess or deficit of resources in the system can be detected centrally by the system operator. As explained above, this information can be retrieved from the uppermost unit of the hierarchical system. The operator does not need any detailed knowledge which units in fact have, e.g., a deficit of resources. Instead, it is enough to provide the necessary resources to the uppermost unit such that said deficit can be equalised.
  • the method according to the present invention in particular by means of the equalisation of resources amongst subordinated units as described above, these resources will be automatically distributed to those units that have reported the deficit of resources .
  • resource equalisation presumes, as already mentioned above, that resources are transferable preferably between arbitrary system units.
  • resources e.g. communication channels
  • a communication channel in a GSM-system which is characterised by its carrier frequency, can have, e.g., an insufficiently high interference level when transferred from one cell to a neighbour cell.
  • said communication channel is not suitable for the type of service for which it shall be applied in the neighbour cell, e.g. with respect to path loss or delay.
  • the system units contain appropriate means not only to determine the number of exceeding resources that shall be indicated to the superior unit but also to determine the characteristics of said resources in order to decide which of said exceeding resources may be transferred.
  • a unit must not only indicate a resource deficit but also the characteristics of the required resources. It is then the responsibility of the superior unit to equalise between matching resource excesses and deficits of its subordinated units .
  • Another aspect to increase the flexibility of the method according to the present invention relates to the equalisation of exceeding resources: In certain situations it would be beneficial for a unit to keep at least some of the exceeding resources.
  • Said method equalises exceeding resources always at first amongst those other units that have the same superior unit and then successively amongst those units that have a common superior unit on a higher level.
  • Said weighting factor could be defined, e.g., for a range [0,1].
  • ⁇ j,i ⁇ l may indicate that a unit requires less additional resources than indicated by the determined resource deficit, e.g. with regard to other units having an even greater need.
  • Other values within this range indicate that only a part of, e.g., the exceeding resources may be distributed to other units.
  • a value e.g., implies that a unit with an excess of four resources provides only one resource for allocation to other units.
  • a superior unit U[j,i] can be calculated as , ⁇ J , i ⁇ R ⁇ u[j,i] ⁇ + ⁇ J _ Struktur
  • the resource excess of U[2,i+1] 134 is reported upwards to U[0,i] 11 because no other subordinated unit of U[l,i] 122 indicated a deficit of resources.
  • the resource deficit of U[2,i-1] 132 cannot be equalised by its superior unit U[l,i-1] 121.
  • U[0,i] 11 is thus the superior unit on the lowest possible hierarchical level of both a subordinated unit U[2,i+1] 134 that has an excess of resources and a subordinated unit U[2,i-2] 131 that has a deficit of resources.
  • this superior unit 11 can start the appropriate equalisation measures as described above in order to transfer the exceeding resources from U[2,i+1] 134 to U[2,i- 2] 131.
  • the receiving unit 131 needs more resources than the delivering unit 134 can provide.
  • This deficit can be monitored by the operator, here by means of resource information that is reported from U[0,i] 11. Then, the operator can, e.g., allocate an additional resource to the system which will automatically be transferred to U[2,i-2] 131 via the intermediate superior units that indicate a deficit of resources, i.e. U[l,i-1] 121.
  • Figure 5 illustrates the various components that are necessary for a unit 50 in a hierarchical system as described above to perform the inventive method as presented in figures 2 and 3.
  • the system unit 50 receives by means of dedicated connections 56 information regarding the resource status of its subordinated units. From this information and its own resources the unit can by help of appropriate means 54 determine its total resource status and via indication means 51 indicate said status to its superior unit. Said indication means 51 are also responsible for an optional weighting of the determined resource excess or deficit.
  • the unit In order to perform the above described equalisation measures the unit must keep track on those subordinated units that have indicated an excess of resources, e.g. by means of a first register 52, and those subordinated units that have indicated a deficit of resources, e.g. by means of a second register 53.
  • the equalising means 55 can allocate the exceeding resources from units in said first register 52 to units in said second register 53 by using appropriate ranking and selecting criterions.
  • Said equalising means 55 could preferably also contain appropriate means to determine resource parameters that support to decide which of said exceeding resources may be transferred or, correspondingly, to determine resource parameters in case of a resource deficit in order to equalise between matching resource excesses and deficits amongst the subordinated units.
  • Said allocated resources are provided to the subordinated units by means of dedicated connections 57.
  • Said network comprises a network operator centre (NOC) 61, which is the central supervising unit of this network, and corresponds to the unit on the uppermost level in the hierarchical system as presented in figure 1.
  • NOC network operator centre
  • a number of mobile switching centres (MSC) 62a-62c representing the next level structure are connected to said network operation centre 61.
  • Each of said mobile switching centres 62a-62c controls a large geographical area that is covered by radio base stations 64a-64c.
  • a plurality of neighboured radio base stations are connected to a radio network controller (RNC) 63a-63b that is responsible for a variety of maintenance functions for said radio base stations and, e.g., for handling of communication connections to and from the network clients.
  • RNC radio network controller
  • the radio base stations 64a-64c and the radio network controllers 63a-63b are represented by the units on the two lowest levels.
  • the radio base stations 64a-64c are located mainly with focus on, e.g., environmental aspects or the expected traffic density in a certain area. This allows a variety of alternatives for the placement of radio base stations :
  • the radio base stations 64a can be directly connected to the radio network controller 63a.
  • Another example is to place the radio base stations 64b in a cascade-like form, e.g. in order to support clients along a highway.
  • the network provider can by help of access licences determine to which degree a network operator can use the facilities of the above described units in an installed network structure.
  • This is advantageous in view of two aspects :
  • the network operator has an increased flexibility to individually adapt the network conditions. Examples for said flexibility are the speed of network expansion or, to a certain extent, the ability to react on changes of the network traffic distribution regarding, e.g., the number of network subscribers or the number and kind of requested services. Said flexibility implies also a cost-optimised network because the network operator only pays for the use of network functionalities that he actually has subscribed to use.
  • the network provider on the other hand, can install standardised network units and easily dedicate the appropriate access licences, e.g.
  • a licence agreement between network provider and network operator can also include the definition of a tolerance range that allows the network operator to access more than the licenced resources during a certain time period.
  • Said access licences for usage of a share of the network unit facilities are mainly determined by the number of network subscribers, i.e. by a number of standardised communication channels, but also by the service that these subscribers request from the network, i.e. the number of such standardised communication channels that are necessary in order to perform the requested service.
  • a standardised communication channel could be, e.g., a 64kbit/s-speech channel complying with certain channel characteristics regarding, e.g., path loss and delay.

  • a network provider installs in a starting phase only a minor system comprising, e.g., a network operation centre 61, one mobile switching centre 62a, and one radio network controller 63a with a number of radio base stations 64a that are appropriately connected to said radio network controller 63a.
  • the network operator only needs to use a minor part of the facilities of said installed network units; although, said units are capable to handle larger amounts of traffic.
  • the network operator thus buys only an appropriate number of resources, i.e. said standardised communication channels, from the network provider.
  • a gradual system expansion could, in a first aspect, imply to connect additional radio base stations to the radio network controller 63a either in order to cover a larger geographical area or in order to be able to increase the number of supported subscribers within a given area.
  • Another reason for a system expansion could be to offer an increased variety of services that are available in the network: Realtime based communication services, for instance, that require a high bandwidth, e.g. video communication connections, will lead to an increase of, e.g., the necessary data rate or uplink and downlink power need, which implies raised demands for the network units.
  • a system expansion causes a higher system load for the system units which in its turn will require additional resources in form of said communication channels in order to serve the increasing number of subscribers and/or in order to be able to perform the more complex services .
  • a system expansion in another aspect could imply to extend the communication network in order to cover a new larger region.
  • radio network controllers 63b and radio base stations 64b-64c that are directly or indirectly connected to the new mobile switching centre 62b.
  • the radio base stations 64a and accordingly the radio network controller 63a need additional communication channels, i.e. resources that permit the usage of currently unused facilities in these units.
