The networking module provides a network access service. The processing unit receives an update checking request from a mobile communication device via the networking module, and determines a delay time period according to a current networking load in response to the update checking request. Also, the processing unit transmits an update configuration file including the delay time period to the mobile communication device via the networking module, so that the mobile communication device downloads the system update file from the remote upgrade server after the delay time period. ## Claims ### Claim 1 A remote upgrade server, comprising: a networking module, configured to provide a network access service; and a processing unit, configured to receive an update checking request from a mobile communication device via the networking module, determine a delay time period according to a current networking load, in response to the update checking request, and transmit an update configuration file comprising the delay time period to the mobile communication device via the networking module, so that the mobile communication device downloads the system update file from the remote upgrade server after the delay time period. ### Claim 2 (depends on 1) The remote upgrade server of claim 1, wherein the update checking request comprises hardware capability information of the mobile communication device, and the processing unit is further configured to determine information concerning one or more available versions of the system update file for the mobile communication device, and include the information concerning the available versions of the system update file for the mobile communication device in the update configuration file. ### Claim 3 (depends on 1) The remote upgrade server of claim 1, wherein the processing unit is further configured to obtain a number of packets currently being processed via the networking module for determining a current traffic rate, and the current networking load is generated according to the current traffic rate. ### Claim 4 (depends on 3) The remote upgrade server of claim 3, wherein the processing unit is further configured to determine an amount of mobile communication devices which are downloading their corresponding system update files from the remote upgrade server, and the current networking load is generated further according to the amount of mobile communication devices. ### Claim 5 A load balancing method for a system update procedure between a mobile communication device and a remote upgrade server, comprising: transmitting, by the mobile communication device, an update checking request to the remote upgrade server; determining, by the remote upgrade server, a delay time period according to a current networking load, in response to the update checking request; transmitting, by the remote upgrade server, an update configuration file comprising the delay time period to the mobile communication device; and downloading, by the mobile communication device, a system update file from the remote upgrade server after the delay time period. ### Claim 6 (depends on 5) The load balancing method of claim 5, wherein the update checking request comprises hardware capability information of the mobile communication device, and the load balancing method further comprises: determining information concerning one or more available versions of the system update file for the mobile communication device; and including the information concerning the available versions of the system update file for the mobile communication device in the update configuration file. ### Claim 7 (depends on 5) The load balancing method of claim 5, further comprising: obtaining a number of packets currently being processed via the networking module for determining a current traffic rate, wherein the current networking load is generated according to the current traffic rate. ### Claim 8 (depends on 7) The load balancing method of claim 7, further comprising: determining an amount of mobile communication devices which are downloading their corresponding system update files from the remote upgrade server, wherein the current networking load is generated further according to the amount of mobile communication devices. ### Claim 9 (depends on 5) The load balancing method of claim 5, further comprising: checking, by the mobile communication device, if there is an error with the system update file after downloading the system update file; and if not, upgrading a system of the mobile communication device using the system update file. ### Claim 10 (depends on 5) The load balancing method of claim 5, wherein the update checking request is transmitted directly from the mobile communication device to the remote upgrade server, without passing through any other devices at the user's end.
