Method of avoiding collisions between access terminals
First Claim
1. A method of avoiding collisions in a mobile communication system having an access network and at least one access terminal, comprising:
- receiving, from the at least one access terminal, a service connection request message including an access terminal identifier and a time identifier;
comparing a time information of the received time identifier to a reset time of the at least one access network; and
if the time information precedes the reset time as a result of the comparison, broadcasting a session close message including the access terminal identifier and the time identifier to the at least one access terminal.

Abstract
A method of avoiding collisions in a mobile communication system having an access network and at least one access terminal. The method includes receiving, from the at least one access terminal, a service connection request message including an access terminal identifier and a time identifier, and comparing a time information of the received time identifier to a reset time of the at least one access network. Further, if the time information precedes the reset time as a result of the comparison, the method includes broadcasting a session close message including the access terminal identifier and the time identifier to the at least one access terminal.

6. A method of avoiding collisions in a mobile communication system having an access network and at least a first and second access terminal, comprising:
-
receiving a service connection request message including a first access terminal identifier and a first time identifier from the first access terminal;
checking whether or not the second access terminal is using an identical access terminal identifier as the received first access terminal identifier;
if the second access terminal is using the identical access terminal identifier, comparing a time information of the first time identifier to a reset time of the access network; and
if the time information precedes the reset time as a result of the comparison, broadcasting a session close message including the first access terminal identifier and the first time identifier to the first access terminal. - View Dependent Claims (7, 8)

9. A method of avoiding collisions in a mobile communication system having an access network and at least one access terminal, comprising:
-
receiving a service connection request message including an access terminal identifier and a time identifier from the at least one access terminal;
comparing a time information of the received time identifier to a current system time of the access network;
if the time information precedes the current system time, comparing the time information to a reset time of the access network; and
if the time information precedes the reset time, broadcasting a session close message including the access terminal identifier and the time identifier to the at least one access terminal. - View Dependent Claims (10, 11, 12)

13. A method of avoiding collisions in a mobile communication system having an access network and at least a first and a second access terminal, comprising:
-
receiving a service connection request message including a first access terminal identifier and a first time identifier from the first access terminal;
comparing a time information of the received first time identifier to a current system time of the access network;
if the time information precedes the current system time, checking whether or not the second access terminal is using an identical access terminal identifier to the received first access terminal identifier;
if the second access terminal is using the identical access terminal, comparing the time information of the first time identifier to a reset time of the access network; and
if the time information precedes the reset time, broadcasting a session close message including the first access terminal identifier and the first time identifier to the first access terminal. - View Dependent Claims (14, 15, 16)

17. A method of avoiding collisions in a mobile communication system having an access network and at least one access terminal, comprising:
-
receiving, via the at least one access terminal, a session close message including an access terminal identifier and a time identifier from the access network;
comparing the received access terminal identifier to an access terminal identifier stored in the at least on access terminal;
if the received access terminal identifier is identical to the stored access terminal identifier, comparing the received time identifier to a stored time identifier corresponding to the stored access terminal identifier of the at least one access terminal; and
if the received access time identifier is identical to the stored access time identifier, initializing the stored access terminal identifier and the stored time identifier of the at least one access terminal. - View Dependent Claims (18, 19, 20)

21. A method of avoiding collisions in a mobile communication system having an access network and at least a first and a second access terminal, comprising:
-
allocating, by the access network, a first access terminal identifier including a first time identifier to the first access terminal;
initializing an access terminal identifier database of the access network;
requesting, by the second access terminal, a data service to the access network using a corresponding second access terminal identifier, which is identical to the first access terminal identifier, and a second time identifier, which is different than the first time identifier;
broadcasting by the access network a session close message including the second access terminal identifier and the second time identifier to the second access terminal; and
closing a session and initializing the access terminal identifier and the first time identifier by the first access terminal.
