Abstract
Abstract Paging command messages received by a BTS, in a cellular radiotelephone system conforming to GSM regulations, are bundled at specific intervals into different types of paging request messages. These paging requests are bundled based on paging group and MS identifiers contained in the paging command message. These paging request messages are buffered for transmission to the MSs. Paging request messages, in a specific embodiment of the invention, are asynchronously divided, for buffering, into two forms as governed by two types of MS identifications; namely, TMSI (temporary mobile station identity) and IMSI (international mobile station identity) types. The bundles are formed from different compositions of these two identification types in order to maximize the buffering capacity. The probability of dropping paging messages is reduced by augmenting the serial synchronous page bundling process with a parallel, primarily asynchronous bundling arrangement. The paging messages are entered into two paging stacks for each paging group. Paging requests are constructed when one stack becomes full.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
236 words
Apparatus for processing paging commands in a cellular radiotelephone system in which paging commands are of at least two types based upon MS IDs in the radiotelephone system, comprising: a base station (BS) (103,104,105) including; (a) a base station controller (BSC) (201) for generating paging command messages in a first and second type format suitable for the first and second MS IDs being paged; including; (i) a connection (106,107,108) to a mobile switching center (MSC) (109) for receiving paging messages conforming to and to be addressed to first and second type MS IDs; characterized by: (ii) data processing circuitry (202) for queuing paging command messages into first and second data stacks of the paging command messages corresponding to predetermined numerical combinations of the first and second type MS IDs defining first, second and third paging request messages; (iii) stored program control circuitry (204,205,206) included in the data processing circuitry for determining when a combination of stored paging commands in at least one of the first and second stacks represents a numerical combination defining one of the first second and third paging requests and for constructing a paging request from a predefined numerical combination of paging commands representing one of the first, second and third paging request format; (b) a base station transceiver (BTS) (311) apparatus connected to the BSC and operative for serially transmitting paging requests to a mobile telephone station (MS) via radio airwave links.
Claim 2
Dependent Claim
51 words
Apparatus for processing paging commands in a cellular radiotelephone system, as claimed in claim 1; wherein the data processing circuitry includes instructions to transmit a paging request to the BTS to be transmitted if the combination of paging commands includes, two commands of two TMSI command types and IMSI command types.
Claim 3
Dependent Claim
56 words
Apparatus for processing paging commands in a cellular radiotelephone system, as claimed in claim 1; wherein the data processing circuitry includes instructions to transmit a paging request to the BTS to be transmitted if the combination of paging commands includes, three commands of two TMSI command types and one of a TMSI and IMSI command type.
Claim 4
Dependent Claim
44 words
Apparatus for processing paging commands in a cellular radiotelephone system, as claimed in claim 1; wherein the data processing circuitry includes instructions to transmit a paging request to the BTS to be transmitted if the combination of paging commands includes, four TMSI command types.
Claim 5
Independent Claim
165 words
A method of processing paging messages in a cellular radio telephone system in which a form of paging messages is governed by types of identifiers used to identify mobile stations (MSs) served in the cellular system with at least two identifiers being used; comprising the steps of: generating paging messages at a mobile switching center (MSC); sending the paging command messages to a base station controller (BSC) which constructs a paging command message for each MS to be paged and forwarding it to a base station transceiver (BTS); characterized by the steps of: queuing the paging command messages at the BTS into paging request messages according to identifiers of MSs; by: bundling the paging command messages into groups of paging command messages according to predefined numerical combinations of paging command messages associated with MSs of each identifier to form specified types of paging requests, and serially transmitting the paging commands of groups of paging commands of complete types of paging requests as a group transmission.
Claim 6
Dependent Claim
31 words
A method of processing paging messages in a cellular radio telephone system as claimed in claim 5; wherein at least two identifiers TMSI and IMSI are used to identify the MSs.
Claim 7
Dependent Claim
48 words
A method of processing paging messages in a cellular radio telephone system as claimed in claim 5; wherein the paging requests are arranged into three groups including at least a first paging request group including at least a paging request for two MSs having the same identifier type.
Claim 8
Dependent Claim
52 words
A method of processing paging messages in a cellular radio telephone system as claimed in claim 5; wherein the paging requests are arranged into three groups including at least a second paging request group including at least a paging request for three MSs with at least two MSs having a TMSI identifier.
Claim 9
Dependent Claim
44 words
A method of processing paging messages in a cellular radio telephone system as claimed in claim 5; wherein the paging requests are arranged into three groups including at least a third paging request group including paging requests for four MSs having a TMSI identifier.
