A method and apparatus for handover in a wireless communication system. A handover indication can be received from a source base station (120) that is connected with a mobile station (110). The handover indication can include a random access channel preamble. The random access channel preamble can include a temporary mobile equipment identifier. The random access channel preamble can be received from the mobile station. A timing advance message can be sent in response to receiving random access channel preamble. The timing advance message can be addressed by the random access channel preamble and a source base station identifier. The connection with the mobile station can be switched from the source base station to a target base station (130).

The system is composed of handset, SIM card, network and international mobile equipment identification (IMEI) server. Using the system, handset user logs on network and sends IMEI number automatically. IMEI server receives IMEI code sent by SIM card, and binds IMEI code with user's IMSI code and number of the handset, building corresponding user's index database. Using IMEI protection cipher carries out authentication of handset user's id. Temporary index for illegal user is built. If illegal user logs on network by using stealing handset, id of illegal user can be known from IMEI.

Exemplary host-instance identifiers may include but are not limited to International Mobile EQUIPMENT Identifiers (IMEI). Optionally, the flash policy configuration is contingent on authentication context data—for example, strength of the authentication (e.g. login / password vs. smartcard authentication or biometric authentication), date of the authentication, and identity provider information.

A system to collect personal and demographic data from user's of cellular mobile communications system devices. This system uses a standard web browser to collect the personal and demographic data instead of the device itself because of the limited interactive experience available to cellular mobile communications system device users. After obtaining data from the user including the user's cellular mobile communications system device's cellular phone number, a message is sent to the device. When a link is the message is activated a small event collection data software module is downloaded to the cellular mobile communications system device. The return message to the data collection entity incorporates the cellular mobile communications system device's International Mobile Equipment Identifier (IMEI) number. This number then ties the event data collected by the module to the personal and demographic information collected from the cellular mobile communications system device user.

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.

The invention discloses a smart card dynamic binding method. An integrated circuit card (UICC) is provided with a first basic file and a second basic file. Before the application selecting process, a global user identification module (USIM) sets a personal identification code (PIN) in the locked state, indicates a USIM service table to a terminal to enable the additional terminal configuration, and receives a configuration downloading instruction. When the USIM determines that the terminal enables a local information command, the USIM actively sends a local information command to the terminal. The UICC receives a terminal response containing the international mobile equipment identity (IMEI) of the terminal, matches the IMEI with an IMEI in the first basic file, sets a status flag for indicating the successful binding into the second basic file after the matching operation is successfully done, starts the initialization process of the USIM, and sets the PIN in the unlocked and invalid state. The invention also discloses a smart card dynamic binding device and a smart card dynamic binding system.

Solutions are described that enable a user equipment (UE) for a communication system always to derive required identifiers using an international mobile subscriber identity (IMSI). The Mobile Network Code (MNC) may be two or three digits long. The SIM may not provide information regarding the MNC length. One solution is based on a table, or list, that is maintained in the UE and which is used to retrieve the MNC for a given Mobile Country Code (MCC). Another solution is based on always taking a predetermined number of digits of the IMSI and determining the MNC in a DNS server. Yet another solution is based on try-and-fail signaling with a DNS server. In consequence, the UE does not always need to know how many digits of the IMSI are used to indicate the mobile network code (MNC), which in some situations is impossible to know anyway.
