Abstract
Abstract A cellular telephone network provides cells P1,P2,P3... which serve the subscribers of more than one subscriber system; e.g. a GSM system and a micro-cellular system. In order to prevent subscribers from one of the systems using all the available channels in any cell at any time, thus blocking out the other system, information is pre-stored for each cell defining the average proportion of the number of bids for channels from subscribers to each of the systems which can be granted at any particular time having regard to the number of channels available at the time of each such bid. In response to a bid from a subscriber to a particular one of the systems, the stored information relating to that system, and in accordance with the number of channels available at the time of that bid, is accessed, and a decision whether or not to grant the bid is made so as to maintain the actual average porportion of bids granted substantially in agreement with the pre-stored value. For example, in response to each such bid a pseudo-random number can be generated: if the value of this number is less than the value pre-stored for the average proportion of bids which can be granted, the bid is granted; otherwise, the bid is blocked.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
80 words
A telecommunications network serving a plurality of different subscribers and having a predetermined plurality of interconnection channels by means of which the subscribers can communicate via the network, characterised by control means (12;16,18,20,22) defining, for each of a predetermined plurality of different types of requests or bids for channels the average proportion of the number of such bids of that type which can be granted having regard to the number of channels available at the time of each such bid.
Claim 2
Dependent Claim
22 words
A network according to claim 1, characterised in that at least part of at least some of the channels operate by radio.
Claim 3
Dependent Claim
17 words
A network according to claim 1 or 2, characterised in that it is at least partly cellular.
Claim 4
Dependent Claim
36 words
A network according to any preceding claim, characterised in that the bids of each of the said different types of bids are bids from subscribers to a respective one of a plurality of different subscriber systems.
Claim 5
Dependent Claim
20 words
A network according to claims 3 and 4, characterised in that one of the subscriber systems is a GSM system.
Claim 6
Dependent Claim
18 words
A network according to claim 5, characterised in that another of the subscriber systems is a microcellular system.
Claim 7
Dependent Claim
33 words
A network according to any one of claims 1 to 3, characterised in that the bids of each of the said different types of bids are bids of a respective type of origin.
Claim 8
Dependent Claim
32 words
A network according to claim 3, characterised in that the predetermined plurality of channels is made up of a predetermined total number of available channels for each cell (P1,P2.....) of the network.
Claim 9
Dependent Claim
28 words
A network according to claim 8, characterised in that the bids of each of the said different types of bids are bids of a respective type of origin.
Claim 10
Dependent Claim
53 words
A network according to claim 9, characterised in that each of the bids of one of the said types of origin is a hand-over bid, that is, a bid for a channel in a particular cell (P1,P2...) in respect of a communication currently in process via a communication channel in another cell (P1,P2...).
Claim 11
Dependent Claim
42 words
A network according to claim 9 or 10, characterised in that each of the bids of one of the said types of origin is an outgoing channel bid, that is, a bid for a channel from a subscriber within the cell (P1,P2...).
Claim 12
Dependent Claim
51 words
A network according to claim 9,10 or 11, characterised in that each of the bids of one of the said types of origin is an incoming channel bid, that is, a bid from outside a particular cell (P1,P2...) for a channel within that cell (P1,P2...) in order to commence a communication.
Claim 13
Dependent Claim
115 words
A network according to any one of claims 8 to 12, characterised in that the control means (12;16,18,20) includes storage means (18) for storing data identifying, for each possible number of available channels, a value for the said average proportion for each of the different types of bids, by accessing means (16) responsive to a bid for a channel of a particular one of the different types of bids and operative in dependence on the number of channels available at the time of that bid to access the corresponding value, and decision means (20,22) responsive to the accessed value to make the decision whether or not to allocate the channel in response to that bid.
Claim 14
Dependent Claim
120 words
A network according to claim 13, characterised in that the decision means comprises means for storing for each of the different types of bids the numbers of previous bids for channels of that type in relation to the number of channels available at the time of each such bid and, for each such bid, whether the decision was or was not to grant the bid, and by means operative in response to a current bid to access that stored information and the stored data relating to the said average proportion and to decide whether or not to grant the current bid in the manner necessary to maintain the actual average proportion in substantial agreement with the stored data relating thereto.
Claim 15
Dependent Claim
76 words
A network according to claim 13, characterised in that the decision means comprises means (20) operative in response to the bid to generate a random number in the same range of numbers as is covered by the said values in the stored data, and comparing means (22) for comparing the random number with the stored value appropriate to the bid and operative to grant the bid if the random number is less than the stored value.
Claim 16
Independent Claim
84 words
A method of operating a telecommunications network serving a plurality of different subscribers, the network having a predetermined plurality of interconnection channels by means of which the subscribers can communicate via the network, characterised by the steps of pre- defining, for each of a predetermined plurality of different types of requests or bids for channels, the average proportion of the total number of such bids which can be granted having regard to the number of channels available at the time of each such bid.
