    • A TMSI, comprising a TMSI identification field and a TMSI generation field, is allocated to a mobile subscriber. For non-restart situations, this involves selecting an unused TMSI identification field value; determining an associated present TMSI generation field value; and performing a normal allocation adjustment to the present TMSI generation field value, thereby producing an adjusted TMSI generation field value. A complete TMSI is generated from the selected TMSI identification value and the adjusted TMSI generation field value. The complete TMSI is allocated to the mobile subscriber. For a normal release situation, the TMSI identification value is processed so that it will be considered unused, and a normal deallocation adjustment is performed to the adjusted TMSI generation field value. In some embodiments, the normal deallocation adjustment restores the TMSI generation field to its earlier value. In an abnormal release, the TMSI generation field value is left unchanged.
    • 包括TMSI识别字段和TMSI生成字段的TMSI被分配给移动用户。 对于非重启情况,这涉及选择未使用的TMSI识别字段值; 确定相关联的当前TMSI生成场值; 对该TMSI生成区域值进行正常的分配调整,从而生成调整后的TMSI生成区域值。 从所选择的TMSI识别值和调整后的TMSI生成字段值产生完整的TMSI。 完整的TMSI被分配给移动用户。 对于正常的释放情况,处理TMSI识别值,使其被认为是未使用的,并且对调整的TMSI生成字段值执行正常的解除分配调整。 在一些实施例中,正常的释放调整将TMSI生成字段恢复到其较早的值。 在异常释放中,TMSI生成域值保持不变。
