84 results about "Mobile equipment identifier" patented technology

A mobile equipment identifier (MEID) is a globally unique number identifying a physical piece of CDMA2000 mobile station equipment. The number format is defined by the 3GPP2 report S.R0048 but in practical terms, it can be seen as an IMEI but with hexadecimal digits.

Mobile device with an obfuscated mobile device user identity

A mobile device identifier (such as an MSISDN) that typically accompanies a mobile device request is replaced with an “enriched” identifier that exposes the mobile device user's home operator but obfuscates the mobile device's (and, thus, the device user's) identity. In one embodiment, the identifier comprises a first part, and a second part. The first part comprises a data string that identifies (either directly or through a database lookup) the mobile device user's home operator. The second part, however, is an opaque data string, such as a one-time-use unique identifier (UID) or a value that is otherwise derived as a function of the MSISDN (or the like). The opaque data string encodes the mobile device's identity in a manner that preferably can be recovered only by the user's home operator (or an entity authorized thereby). When the mobile device user roams into a foreign network, that network receives the enriched identifier in lieu of an MSISDN. The foreign network uses the first part to identify the mobile device user's home network, e.g., to determine whether to permit the requested access (or to provide some other value-added service). The foreign network, however, cannot decode the second part; thus, the mobile device's identity (as well as the identity of the mobile device user) remains obscured. This ensures that the user's privacy is maintained, while preventing third parties from building a profile of the device based on the requests that include the MSISDN or similar identifier.

Key negotiation method and equipment in mobile communication

An embodiment of the invention provides a key negotiation method and key negotiation equipment in mobile communication. The key negotiation method comprises the steps of: generating a pseudo identifier at a mobile equipment side according to a shared password and mobile equipment identifiers in real time, transmitting the pseudo identifier and a group identifier of a mobile equipment group to a server side, acquiring the mobile equipment identifiers by means of the server side according to the pseudo identifier, generating an encrypted key according to random numbers, generating a session keyaccording to the mobile equipment identifiers, the group identifier, a server identifier of the server, an acquired mobile management entity identifier and the encrypted key, returning the server identifier and the mobile management entity identifier to the mobile equipment side, and generating a session key by means of the mobile equipment side through using an algorithm the same as the server side. Through generating the pseudo identifier at the mobile equipment side and using the pseudo identifier for interaction in the signal interaction process, the security of the signal interaction process is improved; and the mobile equipment side and the server side generate the session keys just by adopting the plurality of the identifiers and the random numbers, and save the computational overhead and communication overhead.
