1. A method of transfer of a service session with a mobile terminal from a first wireless local area network to one of its neighbouring wireless local area networks in a telecommunications system by:
providing temporary credentials to the mobile terminal, each being usable for access to a corresponding neighbouring wireless local area network;
the mobile terminal storing said credentials;
the mobile terminal moving to the coverage area of a second network which is one of the neighbouring wireless local area networks;
the mobile terminal detecting that it has so moved;
the mobile terminal identifying, or being informed of the identity of, the second network;
the mobile terminal sending to the second network the temporary credential corresponding to the second network; and
the second network determining the temporary credential received to be valid so permitting service session transfer.
2. A method according to claim 1, further comprising:
checking the identity of the mobile terminal; and
identifying the mobile terminal as valid;
whereupon said providing temporary credentials is undertaken.
3. A method according to claim 2, in which the wireless local area networks are connected to a third generation network,
said checking of the identity of the mobile being undertaken by the third generation network.
4. A method according to claim 1, in which upon said second network determining the temporary credential to be valid, the mobile terminal identifies the current neighbouring wireless local area networks and then corresponding temporary credentials are sent to the mobile terminal;
the mobile terminal stores said credentials, each being usable for access to a corresponding neighbouring wireless local area network to the second wireless local area network.
5. A method according to claim 1, in which only those networks adjacent to the first network and lying in the direction of travel of the mobile terminal are considered its neighbouring networks.
6. A method according to claim 1, in which the temporary credentials expire and are updated upon expiry.
7. A method according to claim 1, in which each temporary credential includes an identifier of the corresponding network.
8. A method according to claim 1, in which each temporary credential is an access code unique to the corresponding network at the time.
9. A method of transfer of a service session with a mobile terminal from one wireless local area network to one of its neighbouring wireless local area networks in a telecommunications system by:
providing temporary credentials to the mobile terminal, each credential being usable for access to a corresponding neighbouring wireless local area network to the first wireless local area network;
a second network which is one of the neighbouring networks receiving from the mobile terminal which has moved to the coverage area of the second network a temporary credential corresponding to the second network;
the second network determining the temporary credential received to be valid so permitting service session transfer to the second network.
10. A method of transfer of a service session to a mobile terminal from one wireless local area network to one of its neighbouring wireless local area networks in a telecommunications system by the mobile terminal:
receiving temporary credentials, each being usable for access to a corresponding neighbouring wireless local area network to the first wireless local area network;
storing said credentials;
moving to the coverage area of a second network which is one of the neighbouring wireless local area networks;
detecting that it has so moved;
identifying, or being informed of the identity of, the second network;
selecting and sending the corresponding temporary credential to the second network; and
receiving an indication that the second network determined the temporary credential received to be valid and so permits service session transfer.
11. An access point of a wireless local area network, the access point comprising a processor configured to:
receive from a mobile terminal which has moved into the coverage area of the network a temporary credential;
check that said received temporary credential is valid:
authorise transfer of a call connection with the mobile terminal to the network in consequence.
12. An access point according to claim 11, in which the processor or access point is configured to beforehand provide the temporary credential for supply to the mobile terminal for use in the event that the mobile terminal moves into the coverage area of the network.
13. An access point according to claim 12, in which the processor or access point is configured to communicate with a third generation network which authenticates the mobile terminal when the mobile terminal is not in the coverage area of the network, and is configured to receive from the third generation network an indication that the mobile terminal is authenticated and so the temporary credential can be provided.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A computer assembly, consisting of:
a display module fastening through a posterior panel by N screw holes aligned to said N of flange apertures near said N of the corners of a processor module by said N of screws; wherein said N is at least four; and
said display module electrically coupling to said processor module through a socket aligned to a first electrical connection socket assembly member to a counterpart connector assembly member;
wherein said display module, includes: an anterior surface opposite facing said posterior panel;
wherein said posterior panel, includes:
said N of said screw holes; and
said first electrical connection socket assembly;
wherein said anterior surface, includes: a LCD display panel;
wherein said processor module, includes:
a frontal surface for engaging said posterior panel, and including: said counterpart connector assembly member;
a first lateral side panel opposite a second lateral side panel; wherein said first lateral side panel couples to two of said N of said flange apertures near two of said N corners of said processor module; and where said second lateral side panel couples to the remaining of said N corners.
2. The computer assembly as set forth in claim 1 wherein said processor module, further comprising:
a processor;
a random access memory; and
a storage memory; and
wherein said processor module further comprises at least one peripheral access port disposed on another outer surface.
3. The computer assembly as set forth in claim 2,
wherein said display module electrically coupling to said processor module, further comprises:
said LCD display electrically coupling to said processor through said first electrical connection socket assembly member electrically coupling to said counterpart connector assembly member.
4. The computer assembly as set forth in claim 1, wherein said display module is engaged to said processor module through movement in an engagement plain perpendicular to said posterior panel.
5. A modular computer, comprising: said computer assembly of claim 1;
wherein said processor module has a lower measure of reliability than said display module.
6. The modular computer as set forth in claim 5,
wherein said modular computer comprising:
at least two computer functions segmented into a set of separate functional modules each categorized with a measure of a reliability characteristic:
wherein said processor module includes a first portion of said set of said separate functional modules if said functional module reliability characteristic measure is below a selected limit value; and
wherein said display module includes the remaining portion of said set of said separate functional modules if said functional module reliability characteristic measure is above said selected limit value.
