Abstract
Abstract The present invention relates to a method in a cellular mobile communication system for transmitting Pages, and such a system. The cells of the system are subdivided into two classes. To which class a cell is assigned is decided by its capacity to transmit Pages or by the amount of Page responses received within the cells. When paging a mobile station, the Page is first transmitted in the cells of the first class. If no response is received to that Page, the Page is transmitted also in the cells of the second class. An advantage is that there will be fewer Pages congested due to lack of capacity for transmission. Transmitted Pages in the cells of the second class are primarily transmitted to mobile stations that are really present within those cells. Thereby the probability increases that all mobile stations will be reached by Pages intended for them.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
178 words
Method in a cellular mobile communication system (PLMN), wherein the cells (C 1 -C 6 ) of the mobile communication system are divided into at least two classes based upon the internal configuration of each of the cells, whereby a Page (P) to a certain mobile station (MS 1 ) is first transmitted into said cells (C 1 , C 3 , C 5 ) assigned to a first class and, if no response is received from the mobile station (MS 1 ), a further Page (P) is transmitted also in cells (C 2 , C 4 , C 6 ) assigned to a second class, and whereby said cells (C 1 -C 6 ) are grouped into location areas (LA) and for each mobile station (MS 1 , MS 2 ) is registered in which of said location areas it is present, in order to primarily transmit a Page intended for a certain mobile station (MS 1 ) in first class cells belonging to a location area within which said mobile station (MS 1 ) is present.
Claim 2
Dependent Claim
178 words
Method in a cellular mobile communication system (PLMN), wherein the cells (C 1 -C 6 ) of the mobile communication system are divided into at least two classes based upon the internal configuration of each of the cells, whereby a Page (P) to a certain mobile station (MS 1 ) is first transmitted into said cells (C 1 , C 3 , C 5 ) assigned to a first class and, if no response is received from the mobile station (MS 1 ), a further Page (P) is transmitted also in cells (C 2 , C 4 , C 6 ) assigned to a second class, and whereby said cells (C 1 -C 6 ) are grouped into location areas (LA) and for each mobile station (MS 1 , MS 2 ) is registered in which of said location areas it is present, in order to primarily transmit a Page intended for a certain mobile station (MS 1 ) in first class cells belonging to a location area within which said mobile station (MS 1 ) is present.
Claim 3
Dependent Claim
29 words
Method according to claim 1 , whereby said cells (C 1 -C 6 ) are assigned to said first class in dependence of their capacity for transmitting Pages (P).
Claim 4
Dependent Claim
31 words
Method according to claim 2 , whereby said cells (C 1 -C 6 ) are assigned to one of said classes in dependence of their level in a hierarchical cell structure.
Claim 5
Dependent Claim
40 words
Method according to claim 3 , whereby said cells (C 1 -C 6 ) are assigned to first class if they have a high level and to second class if they have a low level in the hierarchical cell structure.
Claim 6
Dependent Claim
29 words
Method according to claim 1 , whereby said cells (C 1 -C 6 ) are assigned to first class in dependence of the amount Page responses in each cell.
Claim 7
Dependent Claim
68 words
Cellular mobile communication system (PLMN), characterized by means for registering in which one out of two classes cells of the system belong, means for first transmitting a Page (P) into said cell (C 1 ,C 3 ,C 5 ) belonging to a first of said two classes; means to also transmit a further Page in both classes of cells if no response is received on the first Page.
Claim 8
Dependent Claim
68 words
Cellular mobile communication system (PLMN), characterized by means for registering in which one out of two classes cells of the system belong, means for first transmitting a Page (P) into said cell (C 1 ,C 3 ,C 5 ) belonging to a first of said two classes; means to also transmit a further Page in both classes of cells if no response is received on the first Page.
Claim 9
Dependent Claim
53 words
Cellular mobile communication system (PLMN) according to claim 6 , comprising at least one exchange (MSC) having said means for registering in which out of two classes that cells of the system belong, and having means for controlling said transmitting of Pages within said cells belonging to a first of said two classes.
Claim 10
Independent Claim
112 words
A method for paging a mobile station in a mobile communications system, the mobile communications system comprising a plurality of cells wherein the cells are grouped into location areas (LA) and wherein each mobile station within the communications system registers which location area the mobile station is located within, the method comprising: assigning each of the cells of the mobile communication system to a class based upon the internal configuration of each of the cells; transmitting, in the cells assigned to a first class, a page to the mobile station; and transmitting, if no response is received from the mobile station, a further page in the cells assigned to a second class.
Claim 11
Independent Claim
112 words
A method for paging a mobile station in a mobile communications system, the mobile communications system comprising a plurality of cells wherein the cells are grouped into location areas (LA) and wherein each mobile station within the communications system registers which location area the mobile station is located within, the method comprising: assigning each of the cells of the mobile communication system to a class based upon the internal configuration of each of the cells; transmitting, in the cells assigned to a first class, a page to the mobile station; and transmitting, if no response is received from the mobile station, a further page in the cells assigned to a second class.
Claim 12
Dependent Claim
56 words
The method of claim 8 , wherein said step of transmitting, in the cells assigned to a first class, further comprises: determining the location area in which the mobile station is registered as being located within; and transmitting the page in the cells, within the mobile stations registered location area, which assigned to the first class.
Claim 13
Dependent Claim
28 words
The method of claim 8 , wherein the cells of the communication system are assigned to a class based on the capacity of the cell to transmit pages.
Claim 14
Dependent Claim
30 words
The method of claim 8 , wherein the cells of the communication system are assigned to a class based on the level of each cell within a hierarchical cell structure.
Claim 15
Dependent Claim
37 words
The method of claim 11 , wherein a cell is assigned to the first class if it has a high level and to the second class if it has a low level in the hierarchical cell structure.
Claim 16
Dependent Claim
29 words
The method of claim 8 , wherein the cells within the mobile communications system are assigned to a class based on the number of page responses in each cell.
