Embodiment Construction

[0031] Will explain below, according to the method for establishing the session key of the present invention, be figure 1 The radiocommunication system shown is in use. For discussion purposes only, operation in shared mode is shown, but those in the industry understand that the system can also be operated in non-shared mode. In addition, for the purpose of example only, the method of the present invention is only described in terms of establishing a session key during a call initiation period and a call termination period when there are multiple sessions. It should also be noted that, for simplicity and clarity, the transmission of well-known information, such as mobile station identification information (eg, mobile station identification number, electronic serial number, etc.), between the mobile station and the network is also not described.

Abstract

In the method for establishing a session key, a network and a mobile transfer codes between one another. The mobile and the network perform mutual authentication based on the codes. Besides performing this mutual authentication, the mobile and the network to establish the session key based on the codes. In one embodiment, the messages forming part of the intended session are sent with the codes, and form a basis upon which the codes for authentication have been derived.

Description

[0001] This application is a divisional application of the patent application for invention filed on August 26, 1999, the title of the invention is "Method for Establishing Session Key Agreement", and the application number is 99118100.X. technical field [0002] The invention relates to a method for establishing session keys in a radio communication system. Background technique [0003] There are three main radio communication systems currently in use in the United States, with varying standards. The first system is Time Division Multiple Access System (TDMA), using IS-136 standard, the second is Code Division Multiple Access (CDMA) system, using IS-95 standard, and the third is AdvancedMobile Phone System (AMPS) (Advanced Mobile Station System). Intersystem calls for all three systems use the IS-41 standard, which specifies authentication procedures during call initiation, modification of secret shared data, and so on. [0004] figure 1 A radio communication system is s...
