Wireless telephone service access method |
摘要 |
In a wireless telephone service access method a caller is authenticated by: storing and keeping up to date in service control point databases words identifying each subscription and the corresponding telephone and a secret key; transmitting from the caller's telephone to a service control point words identifying the subscription and the caller's telephone; determining in the caller's telephone a first signature using the secret key and a random number; transmitting the first signature to said service control point over the user to user signaling channel; determining in said service control point a second signature using the secret key and said random number; verifying in said service control point that: the first and second signatures are identical; the word identifying the caller's subscription represents a valid subscription; and the word identifying the caller's subscription matches the word identifying the caller's telephone.
