摘要： A method, an apparatus, and a computer program product for wireless communication are provided in which a scheduling entity determines a first direction of a backhaul link traffic between a first scheduling entity and a second scheduling entity, and determines a second direction of an access link traffic between the scheduling entity and a user equipment (UE) based on the first direction of the backhaul link traffic to reduce potential interference caused by the access link traffic. The scheduling entity transmits or receives the access link traffic in the second direction utilizing at least one of a same transmission resource of the backhaul link traffic. Other aspects, embodiments, and features are also claimed and described.

摘要： Use of available bits in the TEID field of the GTP header to hold information needed to recreate at least a partial state of the session, enough for it to be routed, without waiting for a full state update. The GTP PDU contains the IP Payload with the source and destination IP addresses. The embodiments use that information and the coded TEID bits to provide sufficient routing information so that the packet can be routed without the full state. The TEID is coded to include bits identifying the APN and bits identifying the QCI of the session. A bit can be used to indicate drop if the full state not available. The remaining bits are used to identify unique user sessions. Some of the TEID bits can be encoded with the charging ID. Because sufficient routing information is provided in each packet, a backup gateway does not need to checkpoint.

摘要： Examples provided herein establish a GTP session between a base station and a gateway. A session establishing request is received in response to an attach request from a wireless terminal to the base station, and a gateway located within an edge site is selected based on the session establishing request. The session establishing request is edited to include information designating the gateway and transmitted to the gateway.

摘要： A computer device may include a memory configured to store instructions and a processor configured to execute the instructions to receive a service request from a user equipment (UE) device via a wireless access network; identify a Short Message Service Inter-Working Function (SMS-IWF) device associated with the UE device; and determine that the identified SMS-IWF device is associated with a link failure. The processor may further be configured to instruct the UE device to detach based on determining that the identified SMS-IWF device is associated with a link failure; receive a re-attach request from the UE device, in response to instructing the UE device to detach; and assign a functioning SMS-IWF device to the UE device, in response to receiving the re-attach request.

摘要： A communication system capable of dynamically changing an MME to serve in call processing in accordance with the load condition of the MMEs and the like is provided. A communication system of the present invention includes: communication control apparatuses (10) to (12); and a node apparatus (20) that executes call processing relating to a communication terminal with the communication control apparatuses (10) to (12). The communication control apparatuses (10) to (12) form a context sharing group that shares subscriber data of the communication terminal. The node apparatus (20) selects a first communication control apparatus in the context sharing group, and transmits a call processing message to the first communication control apparatus. The first communication control apparatus executes the call processing using the subscriber data shared in the context sharing group.

摘要： A method, a computer program product and a device, the method may include: receiving a first signature and first control metadata; the first control metadata is indicative of at least one control plane message that was exchanged between a RAN and a core network and was intercepted by a probe; the at least one control plane message relates to a first entity that belongs to or is coupled to the RAN; processing information packets received by a policy enforcer to provide information packet signatures, the information packets undergone an address translation process before being received by the policy enforcer; and enforcing a policy associated with the first entity, the enforcing affects an information packet that is associated with an information packet signature that equals the first signature; wherein the address translation process does no corrupt the first signature.

摘要： When mobility management and bearer management of a mobile terminal (111) that is in an idle state and that is associated with a particular core network node identifier (GUMMEI or V-GUMMEI) are transferred from a first core network node (121S) to a second core network node (121T), a base station (112) configures itself to change, from the first core network node (121S) to the second core network node (121T), a forwarding destination of a Non-Access Stratum (NAS) message that is transmitted by the mobile terminal (111) and that is addressed to the particular core network node identifier (GUMMEI or V-GUMMEI). This contributes to, for example, preventing occurrences of signaling involving a mobile terminal when mobility management and bearer management of the mobile terminal in an idle state are transferred between core network nodes.
