摘要： Upon transmitting privacy information to an MTC server (20) via a network (30, 40), an MTC device (10) includes in a message a field to indicate whether the message contains the privacy information, such that the network (30, 40) can perform authorization for the MTC device (10) and server (20). When the MTC device (10) needs to keep connection with the network (30, 40), the MTC device (10) switches off the functionality of provisioning the privacy information, such that the MTC device (10) still can communicate with the network (30, 40). Upon the transmission of privacy information in an emergency case, the MTC device (10) further includes in the message a content to indicate that the MTC device (10) is an emergency device, such that the network (30, 40) verifies whether the MTC device (10) can be used or activated in the emergency case. Optionally, a USIM for emergency-use is deployed in the MTC device (10).
摘要翻译：在通过网络（30,40）向MTC服务器（20）发送隐私信息时，MTC设备（10）在消息中包括用于指示消息是否包含隐私信息的字段，使得网络（30,40）可以对MTC设备（10）和服务器（20）执行授权。当MTC设备（10）需要保持与网络（30,40）的连接时，MTC设备（10）关闭提供隐私信息的功能，使得MTC设备（10）仍然可以与网络（30,40）。在紧急情况下传输隐私信息时，MTC设备（10）还在消息中包括用于指示MTC设备（10）是紧急设备的内容，使得网络（30,40）验证 MTC设备（10）可以在紧急情况下使用或激活。可选地，在MTC设备（10）中部署紧急使用的USIM。

摘要： A solution of relay node authentication is proposed. The solution includes mutual authentication of relay node and relay UICC, mutual authentication of relay node and network, secure channel establishment between relay UICC and relay node. AKA procedure in TS 33.401 is re-used so that no extra NAS message is needed. IMEI is sent to network in the initial NAS message, according to which MME-RN can retrieve RN's public key from HSS, and perform access control for DeNB. MME-RN will generate a session key based on IMSI, IMEI and Kasme, and encrypt it by RN's public key and send it to RN. UICC will also generate the same key and thus RN can authenticate both UICC and network. When the key or other parameters sent between UICC and RN do not match, UICC or RN will send Authentication Reject message with a new cause to inform network.

摘要： When MME receives Handover required from source eNB/HeNB which contains CSG ID, it verifies whether the CSG subscription data it stores is fresh or expired. If it is expired, or if MME does not have any association data for UE, MME retrieves the latest CSG subscription data from HSS. MME rewrites its stored CSG subscription data with the one retrieved from HSS, if they are different. MME performs access control for the UE according to the CSG ID received from Handover required message and its CSG subscription data. When the access control is failed, a new message List Update Indication is proposed to be sent from source eNB/HeNB to UE. In order to indicate what caused the failure, an appropriate cause in the message is proposed. Upon receiving the message, UE updates its stored CSG whitelist, such that the CSG subscription data in UE and MME are synchronized.
摘要翻译：当MME从包含CSG ID的源eNB / HeNB接收到需要的切换时，验证其存储的CSG订阅数据是新的还是到期的。如果过期，或者MME没有UE的关联数据，则MME从HSS检索最新的CSG订阅数据。如果它们不同，则MME将其存储的CSG订阅数据与从HSS检索到的订阅数据重写。 MME根据从切换所需消息和其CSG订阅数据接收到的CSG ID，执行UE的接入控制。当访问控制失败时，建议从源eNB / HeNB向UE发送新的消息列表更新指示。为了指出什么导致故障，提出了消息中的适当原因。在接收到消息后，UE更新其存储的CSG白名单，使得UE和MME中的CSG订阅数据同步。

摘要： A binder composition containing a polyoxymethylene polymer combined with one or more plasticizers is disclosed that is well suited for use in powder injection molding processes. The binder composition can be combined with inorganic sinterable particles and melt blended together to form a feedstock. The feedstock can be fed through an injection molding process to form a green body. The binder composition of the present disclosure can be easily removed from the green body by contacting the green body with one or more acids. The resulting brown body can then be fed through a sintering process for producing threedimensional articles having complex shapes.

摘要： Upon receiving a triggering message from a MTC server (20), a network (10) verifies if the MTC server (20) is authorized to trigger a target MTC device (30) and also if the MTC device (30) is authorized to respond the triggering message, by comparing an MTC device ID and MTC server ID (and optionally information on subscription) which are include in the triggering message with authorized ones. Upon succeeding in the verification, the network (10) checks a trigger type included in the triggering message to verify if the triggering message is authorized to be sent to the MTC device (30). Upon succeeding in the check, the network (10) forwards the triggering message to the MTC device (30). The network (10) also validates a response from the MTC device (30), by checking whether the MTC device (30) is allowed to communicate with the addressed MTC server (20).
摘要翻译：在接收到来自MTC服务器（20）的触发消息时，网络（10）验证MTC服务器（20）是否被授权触发目标MTC设备（30），并且如果MTC服务器通过将触发消息中包括的MTC设备ID和MTC服务器ID（以及可选的关于预订的信息）与授权的消息进行比较，设备（30）被授权响应触发消息。在验证成功后，网络（10）检查包含在触发消息中的触发类型，以验证触发消息是否被授权发送到MTC设备（30）。一旦检查成功，网络（10）将触发消息转发给MTC设备（30）。网络（10）还通过检查MTC设备（30）是否被允许与寻址的MTC服务器（20）通信来验证来自MTC设备（30）的响应。

摘要： SGSNs in the same pool-area share their resource information by using O&M messages or GTP-C messages. At least one of the SGSNs (Sleeping SGSN) decides to sleep (shut down or run in a low power state), based on the resource information. Then the Sleeping SGSN sends a power down notification to the connected RNC/BSC and SGSNs, thereby preventing the RNC/BSC from selecting the Sleeping SGSN for new connection and handovers, and transferring the load on the Sleeping SGSN to other SGSNs.
