Method and apparatus for allocating radio network temporary identifier
A method and a device for allocating a radio network temporary identifier are provided. According to the utilization of radio network temporary identifier resources, a gateway sends an update message for radio network temporary identifier resources to a micro cell, or a micro cell notifies a gateway of updating an allocation situation of radio network temporary identifier resources of the micro cell so as to avoid waste or insufficiency of resources.
1. A method for allocating a radio network temporary identifier, the method comprising:
determining, by a micro cell and according to a utilization of radio network temporary identifier resources of the micro cell and a first estimation threshold, to update radio network temporary identifier resources of the micro cell;
sending, by the micro cell, an update request for the radio network temporary identifier resources to a gateway;
sending, by the micro cell, a register request message to the gateway, wherein the register request message carries capability information of the micro cell; and
receiving, by the micro cell, a register accept message fed back by the gateway according to the capability information of the micro cell, wherein the register accept message comprises usable radio network temporary identifier resources, an estimation time parameter, a minimum estimation threshold, and a maximum estimation threshold, wherein the radio network temporary identifier resources are represented by an identifier segment, an index, or a prefix segment of the radio network temporary identifier resources, and wherein the estimation time parameter comprises a supplement estimation timer duration and a reclaiming estimation timer duration:
wherein determining to update the radio network temporary identifier resources of the micro cell comprises:
in response to determining that the time that the radio network temporary identifier resources exceed the maximum estimation threshold reaches the supplement estimation timer duration, determining to add radio network temporary identifier resources of the micro cell; or
in response to determining that the time that the radio network temporary identifier resources are less than the minimum estimation threshold reaches the reclaiming estimation timer duration, determining to reclaim radio network temporary identifier resources of the micro cell.
2. The method according to claim 1 , wherein sending the update request for the radio network temporary identifier resources to the gateway comprises sending, by the micro cell, the update request carrying a parameter of the radio network temporary identifier resources to the gateway, wherein the parameter of the radio network temporary identifier resources comprises a number or a percentage of the radio network temporary identifier resources.
3. The method according to claim 2 , wherein if the parameter of the radio network temporary identifier resources that is carried in the update request is adding the number or the percentage of the radio network temporary identifier resources, receiving, by the micro cell, an update response of the radio network temporary identifier resources that is sent by the gateway.
4. A home base station, comprising:
a processor; and
a computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
determining, according to a utilization of radio network temporary identifier resources of a micro cell and a first estimation threshold, to update radio network temporary identifier resources of the micro cell; and
a transmitter, configured to send an update request for updating the radio network temporary identifier resources to a gateway;
wherein the transmitter is further configured to send a register request message to the gateway, wherein the register request message carries capability information of the micro cell;
wherein the home base station further comprises a receiver, configured to receive a register accept message fed back by the gateway according to the capability information of the micro cell, wherein the register accept message comprises usable radio network temporary identifier resources, an estimation time parameter, a minimum estimation threshold, and a maximum estimation threshold, wherein the radio network temporary identifier resources are represented by an identifier segment, an index, or a prefix segment of the radio network temporary identifier resources, and wherein the estimation time parameter comprises a supplement estimation timer duration and a reclaiming estimation timer duration;
wherein determining to update radio network temporary identifier resources of the micro cell comprises:
in response to a time that the radio network temporary identifier resources exceed the maximum estimation threshold reaching the supplement estimation timer duration, determining to add radio network temporary identifier resources of the micro cell; or
in response to a time that the radio network temporary identifier resources are less than the minimum estimation threshold reaching the reclaiming estimation timer duration, determining to reclaim radio network temporary identifier resources of the micro cell.
5. The home base station according to claim 4 , wherein the transmitter sends the update request carrying a parameter of the radio network temporary identifier resources to the gateway, wherein the parameter of the radio network temporary identifier resources comprises a number or a percentage of the radio network temporary identifier resources.
6. The home base station according to claim 5 , further comprising a receiver, wherein if the parameter of the radio network temporary identifier resources that is carried in the update request is adding the number or percentage of the radio network temporary identifier resources, the receiver receives an update response of the radio network temporary identifier resources that is sent by the gateway.
