Description

Mapping method from application program to radio

Technical Field

The present application relates to communications, and more particularly to a method of application to radio mapping for supporting communication techniques of wireless communication devices and for connection manager or coexistence manager interactions in wireless systems.

Background

Wireless communication networks are currently widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, etc. These wireless networks may be multiple-access networks or may support multiple users by sharing the available network resources. Examples of such multiple-access networks are Code Division Multiple Access (CDMA) networks, time Division Multiple Access (TDMA) networks, frequency Division Multiple Access (FDMA) networks, orthogonal FDMA (OFDMA) networks, single carrier FDMA (SC-FDMA) networks.

Multiple radio components, such as Wi-Fi modules, bluetooth devices, and mobile network modules, may be used to support Wi-Fi, bluetooth, and mobile network communications. They also suffer from some drawbacks. One of the main challenges is interference and collision between different radio components.

Existing wireless communication devices may include multiple radios to support communication for different wireless communication networks. Multiple radio components, such as Wi-Fi modules, bluetooth devices, and mobile network modules, may be used to support Wi-Fi, bluetooth, and mobile network communications. They also suffer from some drawbacks. One of the main challenges is interference and collision between different radio components. This may lead to a degradation of the communication quality and a failure to connect to the network, as the radio signal may be disturbed and attenuated during transmission. Furthermore, as more and more wireless communication devices enter the market, the spectrum resources are increasingly scarce, which can also affect the performance of the wireless communication device. At the same time, power consumption of wireless communication devices is also a challenge.

That is, in the present application, which proposes a mapping method of an application program to a radio, the present application has the following advantageous effects:

1. the controller may provide information to the application indicating the radio to which the application is mapped, which may then obtain its connectivity via its selected radio. 2. The controller may be connected with entities in both upper and lower layers to facilitate selection of radios and mapping of applications to radios. 3.

The radio subsystem 230, connection manager 240, coexistence manager 260, and processing core 280 may also include fewer, different, and/or additional managers, controllers, and databases. In general, radio subsystem 230 includes (i) any number of managers and controllers for any number of functions, and (ii) any number of databases for any type of information that may be used to support communications.

5. The configuration file may provide connectivity through an active application on wireless device 110. The configuration file may include a priority for wireless device 110 to perform and obtain a connection specific action. For example, the profile may be by priority of certain radios relative to other radios, priority of certain radios under certain conditions, and so forth. Different profiles may be defined by different entities, such as: a user, a network operator, an Original Equipment Manufacturer (OEM), or a wireless device manufacturer. The configuration files can be customized according to the requirements of different entities, and one or more configuration files can be defined.

6. FIG. 3 illustrates a complete system selection example of a single radio supporting multiple applications; illustrating an example of application flow mobility with complete system selection; illustrating another example of application flow mobility with complete system washing; examples of fractional flow mobilities and fractional flow mobilities for applications are illustrated.

7. Fig. 3 flow mobility and partial flow mobility may be achieved by: (i) Wireless device 110 may be supported by one or more networks, such as a Home Agent (HA), using one or more protocols, such as dual stack mobile IP version (ii).

8. Fig. 4 illustrates an example of partial system selection when wireless device 110 has four active applications APP1-APP4 and includes three available radios R1-R3; an example for applying fractional flow mobility is illustrated, as shown in fig. 4, for partial flow mobility, the application part mapped to different radios may be varied such that different part applications are mapped to a given radio at different times; an example of application part switching is illustrated. Partial handover refers to switching a part of an application from an old radio to a new radio. In general, fractional flow mobility involves selecting different radios for a portion of an application (e.g., as shown in fig. 4C); the proportion of the application mapped to the radio is determined.

9. Fig. 5 illustrates a partial system selection of one application APPm, where wireless device 110 may have N radios R1-RN available, where N is any integer value greater than one, illustrating a partial system selection for multiple applications,

。

10. wireless device 110 may have M active applications APP1-APPM and N available radios R1-RN, where M and N may each be any integer value greater than one. The scores fm, N for application APPm can be mapped to radio Rn, where 0.ltoreq.fm, N <1, m.epsilon. {1, …, M } n.epsilon. {1, …, N } with the sum of all scores for each application being 1.

11. In one design, the mapping function may be defined by one or more of the following: application requirements, priority of application programs, capabilities of the radio, restrictions of the radio, status of the radio, capabilities of the wireless network, and status of the wireless network (e.g., in terms of traffic and/or signaling channel congestion). With these designs, the goals of optimizing network performance and resource utilization can be achieved.

12. The status of wireless device 110 may be determined based on a variety of conditions, such as the battery status of the wireless device, the applications in line waiting to run, the currently active applications, the quality of battery power or network capabilities, and the status of the wireless device. The capabilities of a radio may be quantified by the performance of the radio, the capabilities or features of the radio support, etc. The performance index is a function of time and may depend on a number of factors such as the available and selected radios, the operating state of each radio, channel conditions, etc., the requirements of the active application. The energy metric may be used to account for the impact of an interference environment with coexisting radios on wireless device 110. Generally, as interference increases, application requirements are difficult to meet.

13. In one design, a process of mapping an application to one or more radios is presented. The process first determines the requirements of the application (block 612), then selects a first candidate radio to serve the application (614), and then determines whether the application can be mapped to the first candidate radio based on the requirements of the application and the capabilities of the first candidate radio (block 618). If the first candidate radio is unable to service the application, then the next potential candidate radio may be selected to service the application (block 624). If the answer is "no," a determination is made as to whether all available radios have been considered (block 630). If the answer to block 628 or 630 is "yes," then a set of radios may be selected to service the application (block 620).

14. The mapping of applications to radios may be represented as a matrix containing (i) M rows, corresponding to M active applications, and (ii) N rows, corresponding to N available radios. Each entry of the mapping matrix may indicate a percentage of applications APPm mapped to the radio Rn. The sum of the N entries in each row should be 1. The mapping may be a function of time, application requirements, radio capability or capacity, etc. The mapping matrix may be valid only for a specific time interval or may change with time interval changes. The change in the mapping matrix may reflect a handover of parts of the application or the whole application between radios, a change in the percentage of applications mapped to different radios, etc.

15. In one design, coexistence manager 260 may mitigate interference between multiple active radios operating simultaneously on wireless device 110; protocol frame (time) alignment is one of the methods for aligning radio times of different radio technologies (e.g., LTE and bluetooth) to reduce collisions between radios; knob adjustment is another method for adjusting radio operating conditions to mitigate interference; interference cancellation is also a method for estimating and canceling interference from one or more transmitter radios to a receiver radio.

16. In one design, a process for an active application to perform system selection and a design of 700 are shown, illustrating an exemplary design for performing system selection in a particular sequence of steps. The system selection may also be performed in other ways, for example, using a sequence of steps different from the sequence of the characteristic steps in fig. 4.

17. The design of unidirectional CxM/CnM interactions is illustrated in one design. For unidirectional CxM/CnM interactions, coexistence manager 260 can use interference information and other information that can be used, as well as little or no information from connection manager 240, illustrating the design of bidirectional CxM/CnM interactions. For bi-directional CxM/CnM interactions, control can be from coexistence manager 260 to connection manager 240 for system selection and mobility, and vice versa.

18. The design of iterative bi-directional CxM/CnM interactions is illustrated in one design. In this design, the connection manager 240 may initially provide application requirements to the coexistence manager 260; another design of iterative bi-directional CxM/CnM interactions is also illustrated. In this design, connection manager 240 may provide coexistence manager 260 with an initial mapping applied to the radio.

19. In one design, the system process 1000 is implemented based on the application. Process 1000 may be performed by a wireless device or some other entity device.
