Abstract

Methods and systems for allocating memory of user terminals are disclosed. A user terminal may determine a weight for one or more categories, each category being associated with Internet information to be broadcast. The user terminal also may determine an available memory size of memory and may allocate memory to the one or more categories for storing the Internet information based on the weights and the available memory size.

9. The method of claim 1, wherein the weights of the one or more categories are determined by preferences input at the user terminal.

10. The method of claim 1, wherein the content categories comprise at least one web-based service.

11. The method of claim 1, wherein the content categories comprise a specific link.

12. The method of claim 1, wherein the memory usage information indicates how the allocated portion of the memory is being utilized to store the associated content.

13. The method of claim 1, further comprising:

receiving the content;

determining that a portion of the memory has been allocated to at least one a category associated with the content; and

storing the content in the category.

14. The method of claim 1, wherein the content includes broadcast Internet information comprises a category identifier.

15. The method of claim 1, further comprising:

receiving the content;

determining that a portion of the memory has not been allocated to at least one category associated with the content; and

determining to discard the content.

16. The method of claim 1, wherein the description includes a document type definition (DTD) document for each of the different categories.

17. The method of claim 1, wherein the determined weights are revised based on a user'"'"'s browsing history.

18. An apparatus comprising:

at least one processor; and

at least one memory including computer program code for one or more programs,

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,

receive a category guide, the category guide including a description for one or more categories;

determine a weight for each of the one or more categories, each category being associated with content;

determine an available memory size of the memory, at least partially based on memory usage information and whether the associated content is going to be broadcast in a further time period according to the category guide; and

allocate a portion of the space in the memory to at least one of the one or more categories for storing the associated content based on the weights and the available memory size.
