full_form: Global System for Mobile communications
context: For GSM subscribers, GSM AKA shall always be used. The execution of the GSM AKA results in the establishment of a GSM security context between the user and the serving network domain to which the VLR/SGSN belongs. The user needs to separately establish a security context with each serving network domain. When in a UTRAN, the UMTS cipher/integrity keys CK and IK are derived from the GSM cipher key Kc by the ME and the VLR/SGSN, both R99+ entities. Figure 19 shows the different scenarios that can occur with GSM subscribers using either R98- or R99+ ME in a mixed network architecture. Figure 19: Authentication and key agreement for GSM subscribers Note that the GSM parameters RAND and RES are sent transparently through the UTRAN or GSM BSS. In case of a GSM BSS, ciphering is applied in the GSM BSS for services delivered via the MSC/VLR, and by the SGSN for services delivered via the SGSN. In the latter case the GSM cipher key Kc is not sent to the GSM BSS. In case of a UTRAN, ciphering is
description: GSM (Global System for Mobile communications) is a digital mobile network architecture that provides telecommunications services, including voice and data communication. It is one of the most widely used wireless communication technologies worldwide.
explanation: The text describes GSM as a "digital mobile network architecture" that provides telecommunication services, clearly indicating its role as a type of network.
