AI Technical Summary

Problems solved by technology

Therefore, when the user is at the edge of the cell, there may be a phenomenon that the user cannot be scheduled due to insufficient authorized power, which causes the cell to update
In addition, since the UE has been unable to upload data at this time, RAB RELEASE caused by TRB RESET will occur, which will cause the user to drop calls
[0004] In summary, by using the power authorization method in the prior art, it is possible that the cell at the edge of the cell cannot be scheduled due to insufficient authorized power, so that the cell is updated frequently
In addition, it is easy to cause users to drop calls

Embodiment Construction

[0050]In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0051] The present invention provides a method for power authorization. In this method, Node B will determine the corresponding authorized power according to the power authorization request message sent by UE, and when the determined authorized power is not enough to send a Mac-d PDU, The Node B will perform mandatory authorization on the UE, and send the determined authorized power to the UE, thereby effectively avoiding frequent cell updates.

[0052] figure 1 It is a schematic flowchart of a method for power authorization in the present invention. like figure 1 As shown, in the method for power authorization in the present invention, it mainly includes the following steps:

[0053] Step 101, UE sends a power grant request message...

Abstract

The invention provides a method for authorizing power. The method includes the steps: transmitting a power authorization request message to a base station Node B by UE (user equipment); setting first authorized power according to the received power authorization request message by the Node B; and setting second authorized power and transmitting the second authorized power to the UE by the Node B when at least one Mac-d PDU (protocol data unit) cannot be transmitted by the first authorized power. By the method, frequent cell update can be effectively avoided. In addition, call drop of a user can be effectively decreased.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for power authorization. Background technique [0002] It is stipulated in the existing protocol: For 1.28Mcps TDD mode, the user equipment (UE) sends a power authorization request message carried on the uplink enhanced random access channel (E-RUCCH) to request Node B to perform corresponding power authorization Afterwards, if no corresponding response message is received on the Enhanced Uplink Absolute Access Grant Channel (E-AGCH) within a certain length of time (for example, T-RUCCH), and the above-mentioned power grant carried on the E-RUCCH If the number of transmissions of the request message is not greater than the predetermined maximum number of transmissions N-RUCCH, the UE will send the power authorization request message carried on the E-RUCCH again; after sending the N-RUCCH power authorization request message, the UE will automatically A hys...
