Abstract

Methods and apparatuses are provided for data resource provision. A method may include receiving a request for a first data resource. The request may include an indication of an additional data resource that may be requested in a future request. The method may further include determining the indicated additional data resource. The method may additionally include causing caching of the additional data resource in preparation for a future request for the additional data resource. Corresponding apparatuses are also provided.

Claims

1. A method comprising:

receiving a request for a first data resource, the request comprising an indication of an additional data resource to be requested in a future request;

determining, by request handling circuitry, the indicated additional data resource;

causing caching of the additional data resource in preparation for a future request for the additional data resource;

performing a verification test to determine whether a relationship between the first data resource and the additional data resource satisfies a predefined validity criterion; and

wherein causing caching of the additional data resource comprises causing caching of the additional data resource only in an instance in which it is determined that the relationship between the data resource and the additional data resource satisfies the predefined validity criterion.

2. The method of claim 1, further comprising:

receiving a request for the additional data resource;

causing fetching of the cached additional data resource; and

causing the fetched additional data resource to be provided to the requestor in response to the received request for the additional data resource.

3. The method of claim 1, wherein the first data resource and the additional data resource respectively comprise first and second portions of a map, and wherein performing the verification test comprises determining whether a location of the first portion of the map is within a predefined proximity of the second portion of the map.

4. The method of claim 1, wherein the additional data resource comprises dynamically changing information that must be updated, the method further comprising:

updating the additional data resource prior to causing caching of the additional data resource.

5. The method of claim 4, wherein the additional data resource comprises a portion of a traffic map and the dynamically changing information comprises information about traffic conditions for one or more road segments in the portion of the traffic map, and wherein updating the additional data resource comprises updating the traffic conditions for the portion of the traffic map.

6. The method of claim 1, wherein the indication comprises a parameter of the request, the parameter identifying the additional data resource.

7. The method of claim 1, wherein receiving the request comprises receiving a request at a maps server, the request comprising a request for map data originated by a map application of a client apparatus.

8. An apparatus comprising at least one processor and at least one memory storing computer program code, wherein the at least one memory and stored computer program code are configured, with the at least one processor, to cause the apparatus to at least:

receive a request for a first data resource, the request comprising an indication of an additional data resource to be requested in a future request;

determine the indicated additional data resource;

cause caching of the additional data resource in preparation for a future request for the additional data resource;

perform a verification test to determine whether a relationship between the first data resource and the additional data resource satisfies a predefined validity criterion; and

cause caching of the additional data resource only in an instance in which it is determined that the relationship between the data resource and the additional data resource satisfies the predefined validity criterion.

9. The apparatus of claim 8, wherein the at least one memory and stored computer program code are configured, with the at least one processor, to further cause the apparatus to:

receive a request for the additional data resource;

cause fetching of the cached additional data resource; and

cause the fetched additional data resource to be provided to the requestor in response to the received request for the additional data resource.

10. The apparatus of claim 8, wherein the first data resource and the additional data resource respectively comprise first and second portions of a map, and wherein the at least one memory and stored computer program code are configured, with the at least one processor, to cause the apparatus to perform the verification test at least in part by determining whether a location of the first portion of the map is within a predefined proximity of the second portion of the map.

11. The apparatus of claim 8, wherein the additional data resource comprises dynamically changing information that must be updated, and wherein the at least one memory and stored computer program code are configured, with the at least one processor, to further cause the apparatus to:

update the additional data resource prior to causing caching of the additional data resource.

12. The apparatus of claim 11, wherein the additional data resource comprises a portion of a traffic map and the dynamically changing information comprises information about traffic conditions for one or more road segments in the portion of the traffic map, and wherein the at least one memory and stored computer program code are configured, with the at least one processor, to cause the apparatus to update the additional data resource at least in part by updating the traffic conditions for the portion of the traffic map.

13. The apparatus of claim 8, wherein the indication comprises a parameter of the request, the parameter identifying the additional data resource.

14. The apparatus of claim 8, wherein the apparatus comprises or is embodied on a server apparatus and the received request is originated by an application on a client apparatus.

15. A computer program product comprising at least one non-transitory computer-readable storage medium having computer-readable program instructions stored therein, the computer-readable program instructions configured to cause an apparatus to perform:

receiving a request for a first data resource, the request comprising an indication of an additional data resource to be requested in a future request;

determining the indicated additional data resource;

caching the additional data resource in preparation for a future request for the additional data resource;

performing a verification test to determine whether a relationship between the first data resource and the additional data resource satisfies a predefined validity criterion; and

causing caching of the additional data resource only in an instance in which it is determined that the relationship between the data resource and the additional data resource satisfies the predefined validity criterion.

16. The computer program product of claim 15, further comprising program instructions configured to cause an apparatus to perform:

receiving a request for the additional data resource;

causing fetching of the cached additional data resource; and

causing the fetched additional data resource to be provided to the requestor in response to the received request for the additional data resource.

17. The computer program product of claim 15, wherein the additional data resource comprises dynamically changing information that must be updated, and further comprising program instructions configured to cause an apparatus to perform:

updating the additional data resource prior to causing caching of the additional data resource.
