(3) a test zone downstream of said conjugate site, wherein said test zone comprises a test site wherein an anti-transferrin antibody is immobilized;
(4) a control site wherein a control antibody is immobilized thereto; and
wherein a second strip comprises:
(1) a sample site for applying a sample;
(2) a conjugate site downstream of said sample site, wherein a labeled anti-hemoglobin antibody is deposited at said conjugate site;
(3) a test zone downstream of said conjugate site, wherein said test zone comprises a test site wherein an anti-hemoglobin antibody is immobilized; and
(4) a control site wherein a control antibody is immobilized thereto,
wherein the test strips are calibrated such that a positive signal appears in the test site immobilized with said anti-hemoglobin antibody when hemoglobin is present in said sample at higher than the predetermined value of 0.2 \u03bcgml for hemoglobin, and a positive signal appears in the test site immobilized with said anti-transferrin antibody when transferrin is present in said sample at higher than the predetermined value of 30 ngml for transferrin, such that the signals produced from a test sample permit a differential diagnosis of bleeding from the upper GI tract versus the lower GI tract.
3. The device of claim 1 or 2, wherein said test strip comprises a test membrane made of nitrocellulose.
4. The device of claim 1 or 2, wherein said labeled anti-transferrin antibody and said labeled anti-hemoglobin antibody are both antibodies conjugated to gold particles.
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 method for checking the registration authorization prior to a start of a re-registration process based on a registration query from a mobile radio terminal to at least one access device for an intra-domain handover in a mobile communication network, comprising:
receiving a token, which has been sent by an access device to a mobile radio terminal and has been stored in at least one trust table of at least one access device, by at least one further access device during a registration query from a mobile radio terminal;
comparing the received token with tokens stored in the at least one trust table prior to the start of the registration to verify the registration authorization; and
starting the registration if the registration authorization is verified and the token is invalidated after one-time use and is not used repeatedly.
2. The method according to claim 1, wherein the token is encrypted by means of a key and transmitted to a mobile radio terminal.
3. The method according to claim 1, wherein the registration authorization check is performed prior to the start of the re-registration processes.
4. The method according to claim 1, wherein the binding update process is used for the re-registration process.
5. The method according to claim 1, wherein the authentication and authorization process is used for the re-registration process.
6. The method according to claim 1, wherein the authentication and authorization process and a binding update process are used simultaneously for the re-registration process.
7. The method according to claim 1, wherein at least one access device is an access router.
8. The method according to claim 1, wherein renewal of a binding process is started following successful checking of the authorization by the at least one access device.
9. The method according to claim 1, wherein renewal of the authorization and authentication process is started following successful checking of the authorization by the at least one access device.
10. The method according to claim 1, wherein the token is sent with a message for renewal of a binding between the at least one access device and the mobile radio terminal.
11. The method according to claim 1, wherein the at least one access device sends the token received from the mobile radio terminal to a neighboring access device.
12. The method according to claim 1, wherein the at least one access device sends the token received from the mobile radio terminal to a neighboring access device which is stored in a trust list.
13. The method according to claim 1, wherein the at least one access device stores tokens received from neighboring access devices in the at least one trust table.
14. The method according to claim 1, wherein used tokens are stored in the trust table.
15. The method according to claim 1, wherein the mobile radio terminal sends the token to a further of the at least one access devices during an intra-domain handover.
16. The method according to claim 1, wherein a further of the at least one access devices checks the token according to a period of validity of the token.
17. The method according to claim 1, wherein a further of the at least one access devices checks the token according to generation of the token.
18. The method according to claim 1, wherein a token suffix representing a key is compared with a key computed by the at least one access device.
19. The method according to claim 1, wherein a token includes an identity of the mobile radio terminal.
20. The method according to claim 1, wherein a token includes an identity of the access device generating the token.
21. The method according to claim 20, wherein the token includes a generation time.
22. The method according to claim 20, wherein the token includes a random number.
23. The method according to claim 20, wherein the token includes a digest representing a key.
24. A device for checking the access authorization at a start time of authentication and authorization processes based on a registration query from a mobile radio terminal to at least one access device for an intra-domain handover in a mobile communication network, comprising:
a receiver unit to receive a token and a query concerning the authorization for access by a mobile radio terminal;
a processing unit to generate tokens which are invalidated after one-time use and is not used repeatedly and to check received tokens;
at least one trust table to store generated tokens and tokens received by at least one access device; and
a transmitter unit to send generated tokens to the mobile radio terminal and at least one further access device and to forward the access authorization to further network units.
