A system described herein may serve as an interface between one or more radio units ('RUs') of a wireless network and one or more Distributed Units (“DUs”) of the RAN. The system may maintain information associating a set of RUs with a particular DU. The system may determine that a particular RU of the set of RUs should be disassociated from the particular DU, such as based on load metrics associated with the particular DU exceeding one or more thresholds. The system may disassociate the particular RU from the particular DU by modifying the information associating the set of RUs with the particular DU. The modified may indicate that the particular RU is no longer associated with the particular DU. The system may accordingly facilitate communications between the modified set of RUs, not including the particular RU, and the particular DU.

Systems and methods for dynamic fronthaul gateway

A system described herein may provide for an interface, such as a midhaul interface, between one or more radio elements of a radio access network ('RAN'), such as a Distributed Unit (“DU”) and/or a radio unit (“RU”), and higher layer functions of the RAN, such a Central Unit (“CU”). The interface may provide for the DU to be communicatively coupled to multiple CUs, which may be associated with multiple distinct core networks. The system may route uplink traffic, received from User Equipment (“UEs”) via the RU and the DU, to an appropriate CU. The system may resolve conflicting instructions, for the DU, received from different CUs. The resolution may be performed based on relative priority levels of the CUs or other factors. The system may provide for granular monitoring of traffic parameters on a per-CU basis, thus preserving the privacy of different core networks.

Systems and methods for cooperative radio function for multiple core networks

A system described herein may identify traffic associated with a User Equipment ('UE') that is connected to a first network. The UE may maintain a plurality of UE identities via one or more SIM (“Subscriber Identification Module”) cards, Universal Integrated Circuit Cards (“UICCs”), etc. The system may determine, based on one or more policies, that the traffic is not authorized via the first network. In some situations, the traffic may not be authorized if the first network does not support a type, service, etc. of the traffic. The system may identify a second network, based on the one or more policies, via which the traffic is authorized, and may indicate the second network to the UE. The UE may automatically (e.g., without user intervention) switch to a particular UE identity that is associated with the second network, and may output the traffic via the second network using such UE identity.

Systems and methods for service-based automatic identity switching for a device in a private network

A system described herein may identify sets of seed parameters that are each associated with a respective User Equipment ('UE') of a group of UEs. The system may generate, based on the seed parameters for each UE, a respective set of UE usage metrics for each UE, and may generate a set of aggregate UE usage metrics based on the generated sets of UE usage metrics. The system may compare the aggregate UE usage metrics to a measure of network capacity; determine an amount of time that a measure of UE usage exceeds the measure of network capacity; determine that the amount of time, that the measure of UE usage exceeds the measure of network capacity, exceeds a threshold amount of time; and modify network configuration parameters based on determining that the amount of time, that UE usage exceeds the network capacity, exceeds the threshold amount of time.

Systems and methods for network design and configuration based on user-level usage modeling

An agent is configured to receive queries from an application server in a communication network. The queries are directed to one or more devices in the communication network. The agent selects a communication path for a device from a plurality of communication paths from the application server to the device. The communication path is selected based on a data size that is to be sent to the device as part of the query, a number of devices that are to receive the query, or a combination thereof. The agent transmits the query via the selected communication path. The communication path can be selected based on one or more of a time criticality of the query, a subscription class of a user of the device, a category of a type of the device, an operator-defined influence factor, network conditions along the communication path, a broadcast flag in the query, or a combination thereof.

Selecting communication paths for application server queries of devices

In a method and system for opportunistic delivery of less-than-best-effort application data, a WIN network identified the elements of the wireless network servicing a specified mobile client. One or more elements of the wireless network servicing the specified mobile client monitor the connection state of a mobile client and notify the WIN network of connection state changes so that a chatty application running on an external application server may be notified by the WIN network to deliver packet data when the specified mobile client is connected to the network for some other purpose or when unused network resources are available. In this way, network resource overload caused by chatty applications is reduced.

Method and system for opportunistic delivery of less-than-best-effort application data over communication networks

Handoffs within a wireless communication system () include using a common cell definition code for each of a plurality of microcell BTSs () to facilitate handoffs between a macrocell () and any one of the microcells. In a disclosed example, a common cell definition code such as a PN offset or a scrambling code is used to trigger a handoff from the macrocell () to any one of the microcell BTSs (). A mobile station locate feature identifies which of the BTSs is involved in the handoff. Another common cell definition code is used in one example to trigger all handoffs from any one of the microcells () to the macrocell (). Soft handoff and hard handoff examples are disclosed.

Wireless communication handoffs within a macrocell

Techniques include, in response to a first communication network of a hybrid communication system being aware of a potential for a mismatch of reported authentication parameters associated with a second communication network of the hybrid communication system, wherein the first communication network is used to transport the reported authentication parameters to the second communication network, the first communication network preventing the mismatch of the reported authentication parameters. In one example, the first communication network is an LTE network and the second communication network is a CDMA2000 network.

Prevention of mismatch of authentication parameter in hybrid communication system

In one embodiment, the access terminal (AT) receives a switching ratio, the AT randomly generates a serving priority value from a uniformly distributed random variable, and the AT determines whether to switch from the first carrier and attach to one of the neighboring carriers based on the serving priority value and the switching ratio.

Method of carrier reselection for providing selective traffic redirection

A method for inter-RAT idle handoff is provided by transmitting a handoff initiation signal from a cell associated with a carrier for a first Radio Access Technology (RAT) area, the cell being located in an overlap coverage area with a second RAT area and adjacent to the second RAT area. Spatial hysteresis is provided by the new triggering method to eliminate the ping-pong issue when a mobile move along the border area. The invention also reduces network resource consumption due to ping-ponging.

Method for triggering inter-RAT idle handoff
