Abstract
Abstract A selective call control center (10) is provided for transmission of calls to selective call receivers (14,15,16), such as paging receivers. In a first aspect, priorities are assigned to call sources and to call receivers and the order of transmission of calls is determined by the control center as a function of the priorities of the source and the receiver for each call. In a second aspect, at least one call receiver is provided having at least two addresses and the address to be selected from the at least two addresses for calling that receiver is determined dependent on the priority of the source of the call.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
74 words
A selective call controller comprising: means for receiving calls from call sources, for identifying the source of each call, each of said call sources having a predetermined priority; means for transmitting said calls to call receivers, each of said call receivers having a predetermined priority; and means for determining an order of transmission of the calls to the receivers as a function of the priorities of the source and the receiver for each call.
Claim 2
Dependent Claim
74 words
A selective call controller comprising: means for receiving calls from call sources, for identifying the source of each call, each of said call sources having a predetermined priority; means for transmitting said calls to call receivers, each of said call receivers having a predetermined priority; and means for determining an order of transmission of the calls to the receivers as a function of the priorities of the source and the receiver for each call.
Claim 3
Dependent Claim
78 words
The controller of claim 1, further comprising means for comparing the priority of the source of each call with the priority of the receiver for that call and means, responsive to the means for comparing, for assigning an overall priority to that call, said overall priority corresponding to the greater of said priorities, wherein the overall priority of a call determines the order of transmission of the call relative to other calls having higher or lower overall priorities.
Claim 4
Dependent Claim
89 words
A selective call system comprising: a plurality of call sources having different assigned priorities; a plurality of call receivers having different assigned priorities; a selective call control center including means for assigning priorities to calls received by the control center from the call sources for transmission to the call receivers; transmission means for transmitting the calls to the call receivers; and means for determining an order of transmission of the calls to the receivers as a function of the priorities of the source and the receiver for each call.
Claim 5
Dependent Claim
89 words
A selective call system comprising: a plurality of call sources having different assigned priorities; a plurality of call receivers having different assigned priorities; a selective call control center including means for assigning priorities to calls received by the control center from the call sources for transmission to the call receivers; transmission means for transmitting the calls to the call receivers; and means for determining an order of transmission of the calls to the receivers as a function of the priorities of the source and the receiver for each call.
Claim 6
Dependent Claim
93 words
A selective call system comprising: at least call receiver having at least two addresses; a selective call controller having means for receiving calls from call sources, for identifying the source of each call, and for assigning a priority to said source and having means for determining which of said at least two addresses is to be called dependent upon the priority of the source of the call whereby the priority of a source is used to determine both the order of transmission of calls and the address in the receiver which is called.
Claim 7
Dependent Claim
93 words
A selective call system comprising: at least call receiver having at least two addresses; a selective call controller having means for receiving calls from call sources, for identifying the source of each call, and for assigning a priority to said source and having means for determining which of said at least two addresses is to be called dependent upon the priority of the source of the call whereby the priority of a source is used to determine both the order of transmission of calls and the address in the receiver which is called.
Claim 8
Independent Claim
74 words
A method of assigning priorities to calls received by a selective call control center, comprising the steps of: providing call sources having different assigned priorities; providing call receivers having different assigned priorities; receiving a plurality of calls from the call sources for transmission to the call receivers; and determining an order of transmission of the calls to the receivers as a function of the priorities of the source and the receiver for each call.
Claim 9
Independent Claim
74 words
A method of assigning priorities to calls received by a selective call control center, comprising the steps of: providing call sources having different assigned priorities; providing call receivers having different assigned priorities; receiving a plurality of calls from the call sources for transmission to the call receivers; and determining an order of transmission of the calls to the receivers as a function of the priorities of the source and the receiver for each call.
Claim 10
Dependent Claim
69 words
The method of claim 5, wherein the priority of the source of each call is compared with the priority of the receiver for that call and an overall priority is assigned to that call, said overall priority corresponding to the greater of said priorities, wherein the overall priority of a call determines the order of transmission or the call relative to other calls having higher or lower overall priorities.
Claim 11
Dependent Claim
21 words
The method of claim 6, wherein calls of equal overall priority are formed into a queue on a first-in first-out basis.
Claim 12
Dependent Claim
30 words
The method of claim 7, wherein all calls in a queue of higher overall priority are transmitted before the first call in a queue of lower overall priority is transmitted.
Claim 13
Dependent Claim
40 words
The method of claim 8 further comprising the steps of interrupting a call of lower overall priority, transmitting a call of highest overall priority and re-transmitting the interrupted call when there are no more calls of the highest overall priority.
Claim 14
Dependent Claim
83 words
The method of claim 5 wherein an overall priority is assigned to each call; wherein the overall priority of a call determines the order of transmission of the call relative to other calls having higher or lower overall priorities; wherein a predetermined number of overall priorities are assignable to calls; and wherein a call having the highest overall priority is transmitted on a pre-emptive basis such that calls of lower overall priorities are interrupted to transmit the call having the highest overall priority.
Claim 15
Independent Claim
78 words
A method of operating a selective call system, comprising the steps of: providing call sources having different assigned priorities; providing at least one call receiver having at least two addresses; determining which of said at least two addresses is to be called dependent upon the priority of the source of the call wherein the priority of a source is used to determine both the order of transmission of calls and the address in the receiver which is called.
Claim 16
Independent Claim
78 words
A method of operating a selective call system, comprising the steps of: providing call sources having different assigned priorities; providing at least one call receiver having at least two addresses; determining which of said at least two addresses is to be called dependent upon the priority of the source of the call wherein the priority of a source is used to determine both the order of transmission of calls and the address in the receiver which is called.
