Apparatuses, systems, and methods for prioritized load balancing
View Patent ↗A mobile communication device for prioritized load balancing is provided. In the mobile communication device, a wireless module receives data communication services and a broadcast message from a first service network. Also, a controller determines whether the broadcast message has load balancing information for the first service network and a second service network, and in response to the broadcast message having the load balancing information, generates a random number and determines whether the random number belongs to a restricted priority level according to the load balancing information. The controller further suspends a reselection from the first service network to the second service network, in response to the random number belonging to the restricted priority level.

3. The mobile communication device of claim 2 , wherein the reselection from the first service network to the second service network is suspended for a period of time.
4. The mobile communication device of claim 3 , wherein the broadcast message further comprises system information of the second service network, and the controller further resumes the reselection from the first service network to the second service network in response an expiry of the period of time.
5. The mobile communication device of claim 1 , wherein the controller further performs the reselection from the first service network to the second service network in response to at least one of the following:
the wireless module receiving a broadcast message comprising no load balancing information for the first service network and the second service network; and
the random number not belonging to the restricted priority level.
6. The mobile communication device of claim 1 , wherein the restricted priority level is generated according to one of the following:
an International Mobile Equipment Identity (IMEI);
an International Mobile Subscriber Identity (IMSI) stored in a Subscriber Identity Module (SIM) card coupled to the mobile communication device;
a subscriber priority level stored in the SIM card; and
a second random number generated by the mobile communication device.
7. A prioritized load balancing method for a mobile communication device connected to a first service network, comprising:
receiving data communication services from the first service network;
generating a random number and determining whether the random number belongs to a restricted priority level; and
suspending a reselection from the first service network to a second service network, in response to the random number belonging to the restricted priority level.
8. The prioritized load balancing method of claim 7 , wherein the random number is generated in response to one of the following:
receiving a broadcast message and the broadcast message comprising load balancing information for the first service network and the second service network; and
determining that a signal quality of the received data communication services has fallen below a threshold value.
9. The prioritized load balancing method of claim 8 , wherein the reselection from the first service network to the second service network is suspended for a period of time.
10. The prioritized load balancing method of claim 9 , wherein the broadcast message comprises system information of the second service network, and the prioritized load balancing method further comprises resuming the reselection from the first service network to the second service network, in response to an expiry of the period of time.
11. The prioritized load balancing method of claim 7 , further comprising performing the reselection from the first service network to the second service network in response to at least one of the following:
receiving a broadcast message comprising no load balancing information for the first service network and the second service network; and
the random number not belonging to the restricted priority level.
12. The prioritized load balancing method of claim 7 , wherein the restricted priority level is generated according to one of the following:
an International Mobile Equipment Identity (IMEI);
an International Mobile Subscriber Identity (IMSI) stored in a Subscriber Identity Module (SIM) card coupled to the mobile communication device;
a subscriber priority level stored in the SIM card and;
a second random number generated by the mobile communication device.
13. A mobile communication system for prioritized load balancing, comprising:
a first service network providing data communication services according to a first communication protocol; and
a mobile communication device receiving the data communication services from the first service network, generating a random number and determining whether the random number belongs to a restricted priority level, and suspending a reselection from the first service network to a second service network in compliance with a second communication protocol in response to the random number belonging to the restricted priority level.
14. The mobile communication system of claim 13 , wherein the random number is generated in response to one of the following:
the mobile communication device receiving a broadcast message and the broadcast message comprising load balancing information for the first service network and the second service network; and
the mobile communication device determining that a signal quality of the received data communication services has fallen below a threshold value.
15. The mobile communication system of claim 14 , wherein the reselection from the first service network to the second service network is suspended for a period of time.
16. The mobile communication system of claim 15 , wherein the broadcast message comprises system information of the second service network, and the mobile communication device further resumes the reselection from the first service network to the second service network in response to an expiry of the period of time.
17. The mobile communication system of claim 13 , wherein the mobile communication device further performs the reselection from the first service network to the second service network in response to at least one of the following:
receiving a broadcast message comprising no load balancing information for the first service network and the second service network; and
the random number not belonging to the restricted priority level.
18. The mobile communication system of claim 13 , wherein the restricted priority level is generated according to one of the following:
an International Mobile Equipment Identity (IMEI);
an International Mobile Subscriber Identity (IMSI) stored in a Subscriber Identity Module (SIM) card coupled to the mobile communication device;
a subscriber priority level stored in the SIM card; and
a second random number generated when the mobile communication device is powered on.
