ОПИСАНИЕ



TECHNICAL BACKGROUND

Wireless communication networks provide wireless data services like voice-calling, internet-access, and machine control to wireless user devices like phones, computers, and robots. The wireless communication networks have wireless access points that exchange wireless signals with the wireless user devices. The wireless signals transport user data and network signaling. The wireless access points exchange the user data and network signaling with other network elements to help deliver the wireless data services. Exemplary wireless communication networks include Fifth Generation New Radio (5GNR), Long Term Evolution (LTE), and Institute of Electrical and Electronic Engineers (IEEE) 802.11 (WIFI).

The wireless user devices have circuitry to execute operating systems and user applications. The user applications vary widely and include applications for social networking, media streaming, gaming, messaging, machine control, business transactions, and the like. The user applications often communicate with corresponding application servers to serve the end-user. For example, a video application downloads videos from a video server, and a drone application receives control messages from an air-control server.

Some wireless user devices have multiple radios and can establish multiple wireless links in parallel. For example, a wireless user device may use 5GNR, LTE, and WIFI links at the same time. When using the parallel wireless links, the wireless user devices may transmit redundant data over multiple links for better reliability or they may transmit different data over the links for larger throughput. In a typical scenario, the user applications call the operating system for data communications, and the operating system directs the device to execute network applications to serve the wireless communications. The network applications direct the radios to establish one or more wireless links to serve the user applications.

The user applications and the radios are largely isolated from one another by the operating system and the network applications. The isolation leads to a lack of intelligent coupling between the user applications and the radios in the wireless user devices. Unfortunately, the wireless user devices do not intelligently serve their user applications over parallel wireless connections.

TECHNICAL OVERVIEW

A wireless User Equipment (UE) executes user applications and responsively determines parallel wireless connections and a data allocation from the user applications to the wireless connections. The UE exchanges network signaling with wireless access points and receives network addresses for the parallel wireless connections. The UE receives uplink data from the executing user applications and addresses the uplink data per the data allocation to allocate the data from the user applications to the wireless connections. The UE transfers the uplink data over the parallel wireless connections. The UE receives downlink data for the executing user applications from the wireless connections and transfers the downlink data to the user applications.

FIG. 1 illustrates wireless User Equipment (UE) 110 that serves user applications 101-103 over parallel wireless connections 151-153. UE 110 might be a phone, computer, robot, vehicle, sensor, or some other apparatus with communication circuitry. UE 110 comprises processing circuitry 111 and transceiver circuitry (XCVR CKTRY) 112 that are coupled over data links 113. Processing circuitry 111 stores and executes user applications 101-103. User applications 101-103 and their respective application servers 141-141 support data services like media-conferencing, messaging, social-networking, media-streaming, machine communications, and internet access. FIG. 1 has been simplified for clarity and there are typically more user applications, parallel links, and application servers than the amount shown.

In UE 110, transceiver circuitry 112 comprises antennas, modulators, amplifiers, filters, digital/analog interfaces, microprocessors, memory, and bus connections. Processing circuitry 111 comprises microprocessors, memory, user interfaces, and bus connections. In circuitry 111-112, the microprocessors comprise Digital Signal Processors (DSPs), Central Processing Units (CPUs), Graphical Processing Units (GPUs), Field Programmable Gate Arrays (FPGAs), Application-Specific Integrated Circuits (ASICs), and/or the like. The memories comprise Random Access Memory (RAM), flash circuitry, disk drives, and/or the like. The memories store an operating system, network applications, and user applications.

The microprocessors execute the operating system, network applications, and user applications to wirelessly exchange user data with network elements 120 over parallel wireless connections 151-153. Exemplary network applications comprise Physical Layer (PHY), Media Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), Radio Resource Control (RRC), and Service Data Adaptation Protocol (SDAP). Parallel wireless access connections 151-153 may use Fifth Generation New Radio (5GNR), Long Term Evolution (LTE), International Institute of Electrical and Electronics (IEEE) 802.11 (WIFI), and/or the like.

Network elements 120 comprise radios, computer hardware, and software. Exemplary network elements 120 comprise gNodeBs, Access and Mobility Management Functions (AMFs), User Plane Functions (UPFs), eNodeBs, Mobility Management Entities (MMEs), Serving Gateways (SGWs), WIFI routers, and/or the like. Aggregation (AGG) server 130 and application servers 141-143 comprise computer hardware and software. Network elements 120 exchange the user data with aggregation server 130 over parallel network connections 161-163. Aggregation server 130 exchanges the user data with applications servers 141-143 over respective application connections 171-173. Parallel network connections 161-163 and application connections 171-173 may use IEEE 802.3 (ETHERNET), Internet Protocol (IP), 5GNR, LTE, WIFI, and/or the like.

Initially, parallel connections 151-153 and 161-163 are not established between transceiver circuitry 112 and aggregation server 130. In UE 110, processing circuitry 110 starts to execute user application 101 but does not yet execute user applications 102-103. In response to executing just user application 101, processing circuitry 110 selects parallel wireless connections 151-152 to support user application 101. Processing circuitry 110 does not yet select wireless connection 153. Processing circuitry 110 determines a data allocation for user application 101 over parallel wireless connections 151-152 and network connections 161-162. For example, the data allocation could be 40% of the application data for user application 101 over connections 151/161, and 60% of data for user application 101 over connections 152/162. Separate data allocations for the uplink and the downlink may be used. For example, another data allocation for user application 101 could be 40% of the uplink data over connections 151/161, 60% of the uplink data over connections 152/162, 80% of the downlink data over connections 151/161, and 20% of the downlink data over connections 152/162. The data allocation effectively comprises a Quality-of-Service (QoS) level for user application 101 when the QoS of connections 151/161 differs from the QoS of connections 152/162. Processing circuitry 111 transfers connection requests for parallel wireless connections 151-152 and network connections 161-162 to transceiver circuitry 112 over data links 113. In some examples, the connections requests are Packet Data Network (PDN) Access Point Name (APN) connections requests.

In response to the connection requests, transceiver circuitry 112 exchanges network signaling with wireless access points in network elements 120. The network signaling transfers the connection requests for wireless connections 151-152 and network connections 161-162 from UE 110 to network elements 120. In response to one of the connection requests, network elements 120 establish and link wireless connection 151 and network connection 161 between UE 110 and aggregation server 130. In response to the other connection request, network elements 120 establish and link wireless connection 152 and network connection 162 between UE 110 and aggregation server 130. The establishment of links 151/161 includes the selection of network addresses for UE 101 and aggregation server 130. The establishment of links 152/162 includes the selection of additional network addresses for UE 101 and aggregation server 130. In some examples, the network addresses comprise Internet Protocol (IP) source and destination addresses although other routing technology could be used. Transceiver circuitry 112 transfers the network addresses for wireless connections 151-152 and network connections 161-162 to processing circuitry 111. Using the network addresses, processing circuitry 111 and aggregation server 130 exchange network signaling over transceiver circuitry 112 and network elements 120 to identify UE 110, executing user application 101, the network addresses, and the data allocation.

Processing circuitry 110 receives uplink data from user application 101. Processing circuitry 110 addresses the uplink data to allocate the uplink data from user application 101 to parallel wireless connections 151-152 per the data allocation. For example, processing circuitry 110 may address 30% of the uplink data for wireless connection 151 and address 70% of the uplink data for wireless connection 152 to achieve a 70/30 data allocation. Processing circuitry 110 marks the uplink data to indicate user application 101 and UE 110. Processing circuitry 110 transfers the addressed and marked uplink data to transceiver circuitry 112 over data links 113.

Transceiver circuitry 112 transfers addressed and marked uplink data over parallel wireless connections 151-152 to network elements 120. Network elements 120 transfer the uplink data to aggregation server 130 over parallel network connections 161-162. Based on the application ID and user ID in the uplink data, aggregation server 130 transfers the uplink data for user application 101 from network connections 161-162 to application server 141 over application connection 171. Typically, aggregation server 130 performs a Network Address Translation (NAT) to use a single address pair for UE 110 and application server 141 over application link 171.

Application server 141 transfers downlink data for user application 101 in UE 110 to aggregation server 130 over application link 171--typically using the single address pair for UE 110 and application server 141. Aggregation server 130 addresses the downlink data for network connections 161-162 based on the data allocation. Aggregation server 130 marks the downlink data to indicate user application 101 and UE 110. Aggregation server 130 transfers addressed and marked downlink data over parallel network connections 161-162 to network elements 120. Network elements 120 transfer the downlink data to processing circuitry 111 over parallel wireless connections 151-152 and transceiver circuitry 112. Based on the application ID, processing circuitry 111 transfers the downlink data from wireless connections 151-152 to user application 101.

In UE 110, processing circuitry 110 starts to execute user application 102 along with user application 101. In response to executing user applications 101-102, processing circuitry 110 reselects parallel wireless connections 151-152 to support user applications 101-102. In this case, no additional connections are made for the extra user application. Processing circuitry 110 determines another data allocation for user applications 101-102 over parallel wireless connections 151-152 and network connections 161-162. The data allocation comprises a QoS level for user application 101 and another QoS level for user application 102 as network resources are consumed based on the data allocation. Using the network addresses, processing circuitry 111 and aggregation server 130 exchange network signaling to identify UE 110, user applications 101-102, and the data allocation for user applications 101-102.

Processing circuitry 110 receives uplink data from user applications 101-102. Processing circuitry 110 addresses the uplink data for user applications 101-102 to allocate the uplink data to parallel wireless connections 151-152 and network connections 161-162 per the data allocation. Processing circuitry 110 marks the uplink data for user application 101 to indicate user application 101 and UE 110 and marks the uplink data for user application 102 to indicate user application 102 and UE 110. Processing circuitry 110 transfers the addressed and marked uplink data over transceiver circuitry 112 and parallel wireless links 151-152 to network elements 120. Network elements 120 transfer the addressed and marked uplink data over parallel network connections 161-162 to aggregation server 130. Based on the application IDs and user ID, aggregation server 130 transfers the uplink data for user application 101 from network connections 161-162 to application server 141 over application connection 171. Based on the application IDs and user ID, aggregation server 130 transfers the uplink data for user application 102 from network connections 161-162 to application server 142 over application connection 172.

Application servers 141-142 transfer downlink data for user applications 101-102 to aggregation server 130 over application links 171-172. Aggregation server 130 addresses the downlink data for network connections 161-162 based on the data allocation. Aggregation server 130 marks the downlink data from application server 141 to indicate user application 101 and UE 110 and marks the downlink data from application server 142 to indicate user application 102 and UE 110. Aggregation server 130 transfers addressed and marked downlink data over parallel network connections 161-162 to network elements 120. Network elements 120 transfer the downlink data to processing circuitry 111 over parallel wireless connections 151-152 and transceiver circuitry 112. Based on the application IDs, processing circuitry 111 transfers the downlink data from application server 141 to user application 101 and transfers the downlink data from application server 142 to user application 102.

In UE 110, processing circuitry 110 then starts to execute user application 103 along with user applications 101-102. In response to executing user applications 101-103, processing circuitry 110 now selects parallel wireless connections 151-153 to support user applications 101-103. Thus, a connection is added in response to the additional user application. Processing circuitry 110 determines a data allocation for each of user applications 101-103 over parallel wireless connections 151-153 and network connections 161-163. Processing circuitry 111 transfers a connection request for wireless connection 153 to transceiver circuitry 112 over data links 113.

In response to the connection request, transceiver circuitry 112 exchanges network signaling with one or more wireless access points in network elements 120. The network signaling transfers the connection request for wireless connection 153 and network connection 163 from UE 110 to network elements 120. In response to the connection request, network elements 120 establish and link wireless connection 153 and network connection 163 between UE 110 and aggregation server 130. The connection establishment includes the selection of more network addresses for UE 101 and aggregation server 130. Transceiver circuitry 112 transfers the network addresses for wireless connection 153 to processing circuitry 111. Using the network addresses, processing circuitry 111 and aggregation server 130 exchange network signaling over transceiver 112 and network elements 120 to identify UE 110, user applications 101-103, their network addresses, and their data allocation.

Processing circuitry 110 receives uplink data from user applications 101-103. Processing circuitry 110 addresses the uplink data to allocate the data from user applications 101-103 to parallel wireless connections 151-153 per their data allocation. For example, user applications 101-102 may each receive 25% of connections 151-153 and 161-163, while user application 103 receives 50% of connections 151-153 and 161-163. Processing circuitry 110 marks the uplink data to indicate UE 110 and the appropriate user applications 101-103. Processing circuitry 110 transfers the addressed and marked uplink data to transceiver circuitry 112 over data links 113.

Transceiver circuitry 112 transfers addressed and marked uplink data over parallel wireless connections 151-153 to network elements 120. Network elements 120 transfer the uplink data to aggregation server 130 over parallel network connections 161-163. Based on the application IDs and user ID, aggregation server 130 transfers the uplink data from network connections 161-163 to application servers 141-143 over application connections 171-173.

Application servers 141-143 transfer downlink data for user applications 101-103 in UE 110 to aggregation server 130 over application links 171-173. Aggregation server 130 addresses the downlink data for network connections 161-163 based on the data allocation for each of user applications 101-103. Aggregation server 130 marks the downlink data to indicate UE 110 and the associated user applications 101-103. Aggregation server 130 transfers addressed and marked downlink data over parallel network connections 161-163 to network elements 120. Network elements 120 transfer the downlink data to processing circuitry 111 over parallel wireless connections 151-153 and transceiver circuitry 112. Based on the application IDs, processing circuitry 111 transfers the downlink data from wireless connections 151-153 to user applications 101-103. UE 110 releases wireless connections 151-153 and network connections 161-163 in a reciprocal manner when individual user applications 101-103 stop executing in UE 101.

FIG. 2 illustrates the operation of wireless UE 110 to serve user applications 101-103 over parallel wireless connections 151-153. In UE 110, processing circuitry 110 executes a set of user applications (201). In response to the most recent application launch, processing circuitry 110 selects a set of parallel connections to support the current set of executing user applications (202). Processing circuitry 110 determines an uplink/downlink allocation for each of the user applications over the parallel connections (202). Processing circuitry 111 transfers connection requests (RQs) for the parallel connections to transceiver circuitry 112 (203). Transceiver circuitry 112 transfers the connection requests in network signaling to network elements 120 and receives network addresses for the parallel connections in response (203). Transceiver circuitry 112 transfers the network addresses for the parallel connections to processing circuitry 111 (203).
