Embodiment 1

[0170] Method Embodiment 1: The current specific situation is: the change of the service carried on the E-DCH causes the change of the TTI, the change of the serving cell due to UE movement or the change of the TTI after hard handover, or the occurrence of the SF capability of the new serving cell change, such as image 3 As shown, the processing method adopted in this embodiment includes the following steps:

[0171] Step 302, recalculate the adjustable rate level corresponding to the maximum bit rate of the E-DCH.

[0172] Step 303. Determine whether the highest gear of the adjustable rate gear corresponding to the maximum bit rate of the E-DCH has changed. If so, go to step 304. Otherwise, go to step 301. It is still in a normal state.

[0173] Step 304, reconfigure the E-DCH maximum bit rate, which is the highest gear of the adjustable rate gear corresponding to the E-DCH maximum bit rate, go to step 301, and it is still in the normal state.

Embodiment 2

[0174] Method Embodiment 2: The current specific situation is: when receiving an indication of a non-serving cell processing problem reported by the wireless link of the non-serving cell, such as Figure 4 As shown, the processing method adopted in this embodiment includes the following steps:

[0175] Step 402, according to the adjustable rate gear corresponding to the E-DCH maximum bit rate, judge whether the highest gear rate of the adjustable rate gear is equal to the lowest gear rate, if so, go to step 405; otherwise, continue to step 403.

[0176] Step 403: Downgrade the maximum bit rate of the E-DCH to the lowest rate, and reassign it to the Node B to which each wireless link in the active set belongs.

[0177] Step 404, judging whether the reconfiguration is successful, if successful, go to step 405; otherwise, go to step 301, and it is still in a normal state.

[0178] Step 405, start the maximum bit rate recovery timer, and currently enter the problem state.

Embodiment 3

[0179] Method Embodiment 3: The current specific situation is: except for the other situations of the above-mentioned embodiments, since the processing in other situations does not involve the adjustment of the adjustable rate gear corresponding to the maximum bit rate of the E-DCH, it is processed according to the normal process. The processing method adopted in this embodiment includes the steps of: judging whether the processed UE has an E-DCH, if not, exiting the current processing flow; otherwise, go to step 301, and is still in a normal state.

[0180] A method for processing state migration of a non-serving cell in an HSUPA system, the method includes a preset adjustable rate file, and a maximum bit rate recovery timer; and the initial state is a problem state, and different processing methods are adopted according to the current specific situation Handle the state transition process.

[0181]Step 501, in a problem state. When in this problem state, the maximum bit rate...

Abstract

The invention discloses a solving method of non-service subdistrict disposal problem in high-speed up-grouping connection system, which includes: calculating adjustable velocity gear according to parameter which affects users terminal UE operation velocity requirement; arranging the adjustable velocity gear as the top gear in normal condition, strengthening the top bit velocity of the special message channel E-DCH to the top gear velocity, the wireless network controller RNC collocating E-DCH the top bit velocity to the basic station Node B, and according to the top bit velocity E-DCH of each UE, the Node B reserving user surface hardware source for the attempering result of each UE; and arranging the adjustable velocity gear as the bottom gear on matter condition. The invention also discloses a solving method of non-service subdistrict condition transference in high-speed up-grouping connection system. Adopting the method of the invention can avoid the problem of continuously Nobe B decoding error to finally cause conversation cutting off on the condition of user surface source lack.

Description

technical field [0001] The present invention relates to a technology for solving the problem of non-serving cell processing, and in particular to a solution to the problem of non-serving cell processing and state transition in a High Speed ​​Uplink Packet Access (HSUPA, High Speed ​​Uplink Packet Access) system. Background technique [0002] HSUPA is a new technology proposed by the Third Generation Partnership Project in the Release6 protocol. The adoption of HSUPA technology can improve the throughput of uplink packet data, so as to meet the needs of user terminals (UE, User Equipment) for high-speed uplink services. [0003] In the HSUPA system, when the base station Node B allocates resources for UEs in non-serving cells, it can adopt the allocation method of reserving resources for each UE according to its maximum user plane hardware resource requirements. An allocation manner of dynamically sharing user plane hardware resources among UEs according to current specific n...
