technical field

The invention relates to the research field of a service management method in a TD-SCDMA (Time Division-Synchronous CDMA) mobile terminal, in particular to a service dynamic management method in a TD-SCDMA terminal.

Background technique

TD-SCDMA, as the third-generation mobile communication standard (referred to as 3G) proposed by China, was officially submitted to the ITU (ITU) in 1998. A series of international standardization work such as the integration of the partner project) system and the introduction of new technology features, so that the TD-SCDMA standard has become the first one proposed by China, mainly based on Chinese intellectual property rights, and widely accepted and recognized internationally. wireless communication standards. The high bandwidth of the new-generation broadband wireless mobile communication network provides the necessary conditions for the popularization of the mobile Internet. Compared with traditional networks, TD-SCDMA provides higher communication bandwidth and can support richer services. In order to promote the development of the TD-SCDMA-SCMA industry, it is necessary to develop rich TD-SCDMA services. The various mobile Internet services running on the TD-SCDMA network not only include the existing voice services, supplementary services and data services of the 2.5G network, but also need to develop new services that utilize the characteristics of the 3G network.

Research on the application support environment of TD-SCDMA terminal software, build an open software platform for TD-SCDMA network business applications, including the support framework layer, core application layer and extended application layer, and propose industry business application standards for TD-SCDMA networks .

Among them, the support framework layer provides basic services and underlying engines, including widgets, positioning, indexing, service management, security library, web&wap engine, rule engine, protocol library, DM service, cross-validation engine, etc.; supports dynamic management of non-core services , which can be dynamically loaded and unloaded. Realize the multi-application cooperation model, and call different applications according to different data types; support the mainstream Widget ^{Internet Explorer.lnk} application engine of the mobile Internet.

Due to the different platform hardware capabilities of TD-SCDMA terminals, the types of services that can be supported will be different. Through the service management of the framework layer, the dynamic loading and unloading of non-core services can be realized, so as to achieve flexible adaptation to hardware resources.

Contents of the invention

The object of the present invention is to provide a service dynamic management method in a TD-SCDMA mobile terminal aiming at the deficiencies of the prior art.

The technical scheme that the present invention solves its technical problem adopts is as follows:

1) Create a basic service configuration table when initializing the system. This table is used to index and manage loaded basic services and dynamic services. It records the storage space consumed by each service and the system memory occupied, and also records the overall system Availability of storage space and system memory;

2) Create a dynamic service registry when initializing the system. The dynamic service registry is a database that records driver settings and locations. When the system needs to access hardware devices, device installation must require a driver. This driver is independent of the system, but the system needs to Knowing where to find them, filenames, version numbers, other settings and information, without a registry record of the device, they cannot be used. Whenever a dynamic service is loaded or unloaded, the dynamic service loading or unloading manager will register or unregister the service on the dynamic service registry. When the user is allowed to run a service, the registry can provide the corresponding application program information to the system so that the application program can be found, the location of the correct data file is specified, and other settings can be used;

3) The dynamic service loading and unloading manager accepts user or system instructions to load a dynamic service. It first checks the dynamic service registry to determine whether the entry already exists. If it exists, it returns the service directly; otherwise

4) Check the available resources of the system's overall storage space and system memory in the basic service configuration table. If the available resources are sufficient, the dynamic service loading and unloading manager will register the service-related devices or applications and corresponding settings on the dynamic service registry , and then call the service identifier through the dynamic service registry to identify the corresponding file or data type to call the corresponding service, add the corresponding entry in the basic service configuration table to index this service, and then update the overall system storage space and system memory available resources; otherwise

5) The dynamic service loading and unloading manager adopts the least recently used (LRU) replacement strategy to determine the old service that should be unloaded, and then cancels the registration of the corresponding entry in the dynamic service registry, and indexes the corresponding service in the basic service configuration table. entry and delete this entry, and then update the overall storage space of the system and the available resources of the system memory;

6) Repeat 4) and 5) until successful.

Compared with the background technology, the present invention has the beneficial effects that:

The invention realizes the service dynamic management method in the TD-SCDMA mobile terminal, realizes the dynamic loading and unloading of the non-core business, thereby achieving flexible adaptation to hardware resources. The present invention indexes and manages the loaded basic services and dynamic services through the basic service configuration table and understands the storage space consumed by the services and the occupied system memory, and then registers and cancels the dynamic services through the dynamic service loading and unloading manager In the action of registration, the least recently used (LRU) replacement strategy used can effectively avoid repeated loading and unloading between services. The invention implements dynamic management of non-core tasks, realizes a multi-application cooperative use model, and can effectively utilize TD-SCDMA terminal hardware resources.

(1) Efficiency. The initial response time for loading and unloading of non-core business should not exceed 200ms. The multi-application cooperation model is realized, and different application programs can be called according to different data types, and the overall judgment and call time does not exceed 200ms.

(2) intelligence. The present invention adopts the least recently used (LRU) strategy for dynamic service loading and unloading, and this strategy regards the service that is least used in the most recent period as the removed object. It is based on such an idea that the least recently used service The service of is most likely to no longer be used in the future, so it is more reasonable to treat it as a removed object. It can effectively avoid repeated loading and unloading between services.

(3) Practicality. The operation mechanism of the present invention is simple and clear, and the LRU replacement strategy is easy to implement. It only needs to record the system time of a service recently used in the basic service configuration table, and the service with the earliest system time is taken as the service to be replaced. After repeated verification, this method has good practicability.

Detailed ways

When implementing the service dynamic management method in the TD-SCDMA mobile terminal, considering that the platform hardware capabilities of the TD-SCDMA mobile terminal are different, the corresponding service types that can be supported will be different. Dynamic loading and unloading of core business, so as to achieve elastic adaptation to hardware resources.

The service dynamic management method in the TD-SCDMA terminal of the present invention comprises the following steps:

1. Create a basic service configuration table when initializing the system

This table is used to index and manage loaded basic services and dynamic services, records the storage space consumed by each service and the system memory occupied, and also records the availability of the overall system storage space and system memory.

For example, the total storage space and system memory of a certain TD-SCDMA mobile terminal are regarded as one unit respectively. Initializing the basic service configuration table is to create an empty table structure, and then insert an initial item, that is, the overall storage space of the system and the availability of the system memory, each of which is 1 unit in size.

2. Create a dynamic service registry when initializing the system

The dynamic service registry is a database that records driver settings and locations. When the system needs to access hardware devices, drivers must be required when the device is installed. This driver is independent of the system, but the system needs to know where to find them, file name, version ID, other settings and information, without a registry record for the device, they cannot be used. Whenever a dynamic service is loaded or unloaded, the dynamic service loading or unloading manager will register or unregister the service on the dynamic service registry. When the user is allowed to run a service, the registry can provide the corresponding application Program information is given to the system so that applications can be found, the location of the correct data files is specified, and other settings can be used.

For example, for a TD-SCDMA mobile terminal, examples of user modes controlled by the dynamic service registry include network parameters, browser functionality and features, and so on. Browser functionality and features record the location, file name, version number and other information of the application, so that when the user wants to run the browser, the system will query the registry to obtain the relevant information of the application, so that it can be called correctly. The browser, and the functions and features that the user configures in the browser.

3. The dynamic service loading and unloading manager accepts user or system instructions to load a dynamic service. It first checks the dynamic service registry to determine whether the entry already exists. If it already exists, it returns the service directly.

For example, the current dynamic service registry of a TD-SCDMA mobile terminal already has some equipment and application information required by non-core services, such as services such as a, b, and c. Its dynamic service loading and unloading manager accepts instructions to load dynamic services, and it will query the relevant device and application information in the dynamic service registry. If it finds that a service already exists in the registry, it will directly obtain it through this registry a Service necessary information to run and control attached devices and applications and correctly respond to user input.

4. Otherwise, check the available resources of the system's overall storage space and system memory in the basic service configuration table. If the available resources are sufficient, the dynamic service loading and unloading manager will register the service-related devices or applications and corresponding services on the dynamic service registry. Then call the service identifier through the dynamic service registry to identify the corresponding file or data type to call the corresponding service, add the corresponding entry in the basic service configuration table to index this service, and then update the overall system storage space and Available resources of system memory

For example, the current dynamic service registry of a TD-SCDMA mobile terminal already has some equipment and application information required by non-core services, such as services such as a, b, and c. If it is found that the d service does not exist in the registry, then the dynamic service loading and unloading manager will register the service-related devices or applications and corresponding settings on the dynamic service registry, and then obtain the d service through the registry Necessary information to run and control attached devices and applications and correctly respond to user input.

5. Otherwise, the dynamic service loading and unloading manager adopts the least recently used (LRU) replacement strategy to determine the old service that should be unloaded, and then cancels the registration of the corresponding entry in the dynamic service registry, and indexes this entry in the basic service configuration table. Serve the corresponding table entry and delete this table entry, and then update the system's overall storage space and available resources of system memory

For example, in the current basic service configuration table of a TD-SCDMA mobile terminal, the overall system storage space and available system memory resources are insufficient, and some non-core business required equipment and application information already exist in the dynamic service registry, such as a, b , c, d and other services. Therefore, the dynamic service loading and unloading manager adopts the Least Recently Used (LRU) replacement strategy to determine the old service that should be unloaded, such as a service, which has been used the least recently, so it unregisters the corresponding service in the dynamic service registry Table entry, index the corresponding table entry of a service in the basic service configuration table and delete this table entry, and then update the overall storage space of the system and the available resources of the system memory.

6. Repeat steps 4 and 5 until successful

For example, after a certain TD-SCDMA mobile terminal repeats steps 4 and 5 several times, when the available resources of the overall system storage space and system memory in its basic service configuration table are sufficient, the new service can be loaded.
