Systems and methods for MME adaptive selection are described. The method includes: initializing a health checkup algorithm at an eNodeB for each MME connected to as per configuration values; starting a health check timer for each MME; continuing with an Initial Attach procedure for incoming calls based on SAE-Temporary Mobile Subscriber Id (S-TMSI), (Globally Unique MME Identifier) GUMMEI, or capacity/load balancing considerations; on every UE attach attempt, incrementing a total calls count; and on every S1 AP Error Indication/no response from an ME, incrementing a total fail calls count; determining when the health check timer for an MME expires; calculating a failed calls/total calls percentage value. Based on the value of the timer, appropriate action is taken.

A communication method and an apparatus are provided herein. The method includes: sending, by a mobility management entity (MME), a track area update (TAU) accept message to a user equipment (UE), the TAU accept message comprising an identifier constructed from at least a resource pool identifier (pool-ID) that identifies a resource pool in a public land mobile network (PLMN), a mobility management entity identifier (MME-ID) that uniquely identifies the MME within the resource pool, and a UE temporary identifier that uniquely identifies the UE within the MME; and receiving, by the MME, a TAU complete message from the UE.

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.

A method performed by a communications device, the method comprising allocating a fraction of the data for transmitting to a first infrastructure equipment using a first carrier frequency, allocating a remainder of the data for transmitting to a second infrastructure equipment using a second carrier frequency, transmitting the fraction of data using the first carrier frequency and the remainder of data using the second carrier frequency, determining an attribute associated with communicating the data from the communications device to the first infrastructure equipment using the first carrier frequency based upon signals received from the first infrastructure equipment, modifying the fraction based on at least the determined attribute, and transmitting the data using at least one of the first and second carrier frequencies according to the modified fraction.

Systems and methods for MME adaptive selection are described. The method includes: initializing a health checkup algorithm at an eNodeB for each MME connected to as per configuration values; starting a health check timer for each MME; continuing with an Initial Attach procedure for incoming calls based on SAE-Temporary Mobile Subscriber Id (S-TMSI), (Globally Unique MME Identifier) GUMMEI, or capacity/load balancing considerations; on every UE attach attempt, incrementing a total calls count; and on every S1 AP Error Indication/no response from an ME, incrementing a total fail calls count; determining when the health check timer for an MME expires; calculating a failed calls/total calls percentage value. Based on the value of the timer, appropriate action is taken.

A method for rules-based overload control for 5G services includes configuring, at an intermediate or a producer network function (NF), overload message handing rules, wherein at least some of the rules include destination network name (DNN), network subscription, network location, or a network slice identifying parameter or any parameter/attribute defined by 3GPP/vendor as rule selection criteria. The method includes a guaranteed processing bandwidth of the intermediate or producer NF with at least some of the overload message handling rules, receiving a first message at the intermediate or producer NF, determining that an overload condition exists, identifying that the first message includes parameters that match the rule selection criteria for one of the overload message handling rules, determining, that a portion of the guaranteed processing bandwidth of the intermediate or producer NF for the matching overload message handling rule is available to process the first message, processing the first message, and updating a message count for the overload message handling rule.

This disclosure provides a method of balancing load in a cellular telecommunications network, the cellular telecommunications network having a first transceiver, a second transceiver, a first core network and a plurality of User Equipment (UE) the method including connecting a UE of the plurality of UEs to the first transceiver and second transceiver in a first non-standalone deployment mode in which the UE communicates control plane traffic and user plane traffic with the first transceiver and communicates user plane traffic only with the second transceiver; monitoring a load of one of more of the first transceiver, second transceiver and the first core network; determining whether the load satisfies a trigger threshold; and, if it does, responding by, connecting the UE to the first transceiver and second transceiver in a second non-standalone deployment mode in which the UE communicates control plane traffic and user plane traffic with the second transceiver and communicates user plane traffic only with the first transceiver.

A network device may receive historical data identifying historical error data and error data categorizations associated with a first core network and may store the historical data in a data structure. The network device may receive a request associated with a user equipment and may receive error data from the first core network based on the request. The network device may receive network health data identifying load levels and health of the first core network and a second core network. The network device may determine possible cause data identifying causes associated with the error data based on the historical data, the error data, and the network health data. The network device may generate a cause code for the user equipment based on the possible cause data and may provide the cause code to the user equipment.

A method and an apparatus for identifying a UE in an SAE network, and an MME are provided herein. The method includes: receiving an SAE-TMSI which is allocated to a UE that accesses an SAE network and includes at least: a pool-ID, an MME-ID, and a UE temporary identifier; using the SAE-TMSI to temporarily identify the UE in the SAE network.
