    摘要： Embodiments of this application provide a device identifier access method and an apparatus, and relate to the field of communications technologies, so as to reduce a risk of privacy leakage caused by excessive access to a device identifier by an application program, and improve device security of a terminal. The method includes: receiving, by a terminal, request information for accessing a first device identifier by a target application; in response to the request information, determining, by the terminal, first access permission used when the target application accesses the first device identifier, where the first access permission includes one of the following: prohibiting access to the first device identifier, allowing access to a real value of the first device identifier, and allowing access to a dummy value of the first device identifier; and when the first access permission is allowing access to the dummy value of the first device identifier, returning, by the terminal, the dummy value of the first device identifier to the target application, where the dummy value of the first device identifier is obtained after anonymization processing is performed on the real value of the first device identifier.

    摘要： In a home network of a communication system, wherein one or more cryptographic key pairs are provisioned for utilization by subscribers of the home network to conceal subscriber identifiers provided to one or more access points in the communication system, the method comprises provisioning one or more privacy managing entity identifiers for utilization by the subscribers when providing their concealed subscriber identifiers to the communication system. Each of the one or more privacy managing entity identifiers identify a given privacy managing entity in the communication system configured to de-conceal a given subscriber identifier.

    摘要： The present invention relates to a method for wireless communication, comprising receiving, by a second serving network, an attach request originated from a user equipment, the attach request carrying a temporary identifier; transmitting, by the second serving network, a request message to a first serving network that previously served the user equipment to obtain a user context from the first serving network according to the temporary identifier carried in the attach request; receiving, by the second serving network, a response message from the first serving network indicating a failure in retrieving the user context; transmitting, by the second serving network in response to the failure, an identity request message to the user equipment, wherein the identity request message includes an identity type indicating an encrypted subscription identity; and receiving, by the second serving network, an identity response from the user equipment including the encrypted subscription identity.
