摘要： Solutions for providing a data traffic session with proxy-call session control function (P-CSCF) restoration include: receiving an indication, by an application server (AS), that a user equipment (UE) is registered with a first proxy node (e.g., a P-CSCF); subscribing, by the AS, with a status repository, to a status of the first proxy node; receiving, by the AS, from the status repository, an indication that the first proxy node is unavailable; based on at least receiving the indication that the first proxy node is unavailable, transmitting, by the AS, to a subscriber information node, a first message triggering proxy node restoration; receiving an indication, by the AS, that the UE is registered with a second proxy node different than the first proxy node; and based on at least receiving a session initiation message, establishing the data traffic session for the UE with the second proxy node.

摘要： A method for discovering an interface session within a wireless communication network is discussed herein. The method includes establishing an Internet Protocol (IP) packet-switched network registration between a first node of a plurality of nodes within the wireless communication network and a second node of the plurality of nodes. The method further includes, requesting, by a third node of the plurality of nodes from a fourth node of the plurality of nodes, service for a call of a mobile device within the wireless communication network. Based upon not having an appropriate interface session established between the first node and the fourth node, the method also includes performing, by the fourth node, an interface session discovery. Based at least in part on the interface session discovery, a dedicated bearer is established at the second node for the call.

摘要： Systems and methods for network-controlled scam/robocall handling are described. When an incoming call destined for a user device is detected, if the user device is subscribed to network-controlled scam/robocall handling, the incoming call is handled at the network according to the subscription. If user preferences are specified, the call may be blocked, forwarded to another number, sent directly to voice mail, or delivered to the device. How a call is handled may be determined based on a category associated with an originating number of the incoming call.

摘要： Systems and methods for network-controlled personal number handling are described. When an incoming call destined for a user device is detected, if the user device is subscribed to network-controlled personal number handling, the incoming call is handled at the network according to the subscription. If an originating number associated with the call has been previously specified by the user, the call may be blocked, forwarded to another number, or sent directly to voice mail. How a call is handled may be determined based on user-specified preferences associated with an originating number of the incoming call.

摘要： In some examples, an anchoring network system (e.g., PCSCF) of a telecommunications network can receive first data requesting a network service (e.g., eSRVCC) from a network terminal (e.g., UE). The anchoring system can determine that the network service is not supported in an access network to which the terminal is connected. The anchoring system can determine second data that does not request the predetermined network service, and transmit the second data to a core network system (e.g., SCSCF). In some examples, an application server can retrieve location information (e.g., LAC) of the terminal and determine that the service is not supported based on the location information. In some examples, an anchoring network system can remove a network-service system (e.g., ATCF or SCCAS) from a signaling chain associated with the terminal. In some examples, the terminal can determine whether SRVCC is supported based on an attach result.

摘要： A communication session can be restored in the event of serving call session control function (S-CSCF) node unavailability and/or application server (AS) unavailability by storing, prior to IMS unavailability, attribute-value pairs (AVPs) at a home subscriber server (HSS). These AVPs can be used independently by individual IMS nodes to restore a communication session due to an unavailable IMS node. When a first S-CSCF node becomes unavailable, a proxy CSCF (P-CSCF) node can send a SIP request originating from the UE to a second S-CSCF node. The second S-CSCF node can then send a request to the HSS for an identifier of an AS associated with the UE. Upon receipt of the AS identifier (e.g., an active AS name AVP), the second S-CSCF node can send the SIP request to the AS in order to restore the communication session for the UE.
摘要翻译：通过在IMS不可用之前存储属性值，可以在服务呼叫会话控制功能（S-CSCF）节点不可用和/或应用服务器（AS）不可用的情况下恢复通信会话在家庭用户服务器（HSS）处配对（AVP）。由于不可用的IMS节点，这些AVP可以由单独的IMS节点独立使用以恢复通信会话。当第一S-CSCF节点变得不可用时，代理CSCF（P-CSCF）节点可以将源自UE的SIP请求发送到第二S-CSCF节点。然后第二S-CSCF节点可以向HSS发送请求以获取与UE相关联的AS的标识符。在接收到AS标识符（例如，活动的AS名称AVP）时，第二S-CSCF节点可以向AS发送SIP请求以便恢复UE的通信会话。

摘要： In some implementations, a telecommunications network can include a core network device. The core network device can receive from a session-originating device an initiation request of a communication session, the initiation request including information of a destination and information of media capabilities. The core network device can determine network-location information of the destination, retrieve from a capability registry modification information corresponding to the network-location information, and modify the information of the media capabilities based at least in part on the modification information. The core network device can transmit the initiation request including the modified information of the media capabilities to another core network device corresponding to the network-location information. The core network device can also determine that the information of the one or more media capabilities does not correspond to the retrieved capability information and transmit a session-failure indication to the session-originating device.

摘要： Systems, devices, and techniques described herein relate to intelligently allocating network resources to Quality of Service (QoS)-sensitive data traffic. An example method includes identifying a request to deliver QoS-sensitive services to a User Equipment (UE) over at least one delivery network. The at least one delivery network may include at least one reserved resource and at least one pooled resource. The QoS-sensitive services are determined to be delivered over the at least one pooled resource. In addition, delivery of the QoS-sensitive services is caused over the at least one pooled resource.

摘要： When an application server receives an invite message associated with a call from an originating user equipment (UE) to a terminating UE, the application server can determine if one of the originating UE or the terminating UE is associated with a scammer. If the originating UE is associated with a scammer, the application server can remove the scammer's caller identification (ID) information from the invite message, such that a user of the terminating UE cannot use that caller ID information to make a return call to the scammer. If the terminating UE is associated with a scammer, the application server can remove caller ID information associated with the originating UE from the invite message to hide the calling party's information from the scammer, and/or invoke playback of a scam announcement to the originating UE to warn the calling party that they are calling a scammer.
