The method includes detecting, at a mobile device, that one component of multiple components for providing mobile traffic management services is non-operational, at capacity, or near capacity, identifying the mobile device serviced by the one component, retrieving information for the mobile device serviced by the one component, from a repository coupled to the one component and the multiple components, re-assigning the mobile device originally serviced by the one component to another one of the multiple components for servicing, and communicating with the another one of the multiple components for servicing communication requests of the mobile device. ## Claims ### Claim 1 A method for providing fault tolerance in mobile traffic management services, the method, comprising: detecting that a first component of a set of multiple redundantly clustered components for providing mobile traffic management services is non-operational, at capacity, or near capacity; identifying a mobile device serviced by the first component; retrieving information for the mobile device serviced by the first component, from a repository coupled to each of the multiple redundantly clustered components (“common repository node”); re-assigning the mobile device originally serviced by the first component to a second component of the set of the multiple redundantly clustered components for servicing; in response to detecting that the first component is non-operational, at capacity, or near capacity, communicating, via the common repository node, with the second component of the multiple redundantly clustered components to service communication requests of the mobile device such that mobile traffic is optimized using subscription information for the mobile device, wherein the subscription information includes at least one of user information, user behavior information, device information, and information regarding mobile applications on the mobile device, and wherein mobile traffic is optimized by performing at least one of batching requests originated from the mobile device, categorizing the mobile traffic based on whether it is foreground or background traffic, prioritizing the mobile traffic based on time criticality, aligning or delaying polling requests from the mobile device, monitoring application behavior on the mobile device, and monitoring user behavior on the device. ### Claim 2 (depends on 1) The method of claim 1, wherein, when it is detected that the first component is non-operational, at capacity, or near capacity, sending invalidations of cache entries on the mobile device to the mobile device originally serviced by the first component from one of the remaining components of the set of multiple redundantly clustered components. ### Claim 3 (depends on 2) The method of claim 2, wherein sending invalidations of cache entries includes sending the invalidations of cache entries in clear text and not encrypted form. ### Claim 4 (depends on 1) The method of claim 1, wherein the mobile traffic is optimized by a local proxy. ### Claim 5 (depends on 1) The method of claim 1, wherein the mobile traffic is optimized by a proxy remote from the mobile device. ### Claim 6 A mobile device, comprising: a processor, wherein the processor is configured to: detect an operability health status of a first component of a set of multiple redundantly clustered components for providing mobile traffic management services; receive communications in response to a request from the mobile device serviced by a second component of the set of multiple redundantly clustered components when the detected operability status is not within acceptable ranges, wherein the second component is associated with the first component; and in response to detecting that the operability status is not within acceptable ranges, optimize mobile traffic using subscription information for the mobile device, wherein the subscription information includes at least one of user information, user behavior information, device information, and information regarding mobile applications on the mobile device, wherein mobile traffic is optimized by performing at least one of batching requests originated from the mobile device, categorizing the mobile traffic based on whether it is foreground or background traffic, prioritizing the mobile traffic based on time criticality, aligning or delaying polling requests from the mobile device, monitoring application behavior on the mobile device, and monitoring user behavior on the device. ### Claim 7 (depends on 6) The mobile device of claim 6, wherein the second component is associated with the first component based on subscription information of either of the first component or the second component. ### Claim 8 (depends on 6) The mobile device of claim 6, wherein the operability health status includes a determination that the first component is non-operational. ### Claim 9 (depends on 6) The mobile device of claim 6, wherein the operability health status includes a determination that the first component is at capacity. ### Claim 10 (depends on 6) The mobile device of claim 6, wherein the operability health status includes a determination that the first component is near capacity. ### Claim 11 (depends on 6) The mobile device of claim 6, wherein the device is further configured to receive invalidations of cached entries in clear text and not encrypted form. ### Claim 12 (depends on 6) The mobile device of claim 6, wherein the device is configured for optimizing traffic by a local proxy on the device.
