Embodiment 1

[0078] The common feature of embodiment 1 and embodiment 2 is that the control RNC needs to obtain the capability information of whether the mobile station supports the enhanced paging feature through some means; Support the capability information of the enhanced paging feature to jointly determine which channel to send the paging message. The difference is that, in the first embodiment, it is obtained from the paging request message sent by the serving RNC, but in the second embodiment, it is obtained from the uplink RRC message sent by the mobile station to the network side.

[0079] A method for a mobile station to determine a paging transmission channel in Embodiment 3 of the present invention, such as Figure 8 shown, including the following steps:

[0080] Step s801, each time the serving RNC allocates a new U-RNTI to the mobile station, or each time the identity of the serving RNC changes, the RRC message sent by the network side to the mobile station carries an indica...

Embodiment 3

[0089] In Embodiment 3, only the mobile station that meets the following conditions will read the extended bits in the PICH frame: the mobile station is in the URA_PCH state, the mobile station supports the enhanced paging feature, and the cell it is currently in supports the enhanced paging feature, and the mobile station The serving RNC of the station does not support the enhanced paging feature (probably because the SRNC is an RNC of a version before Rel 7, or an RNC of a version after Rel 7 but does not support the enhanced paging feature), and the mobile station that does not meet the above conditions even Reading this extension bit also ignores its meaning.

[0090] From the above analysis, it can be known that the paging that does not meet these conditions will still be sent using the HSDPA channel; even if these conditions are met, the paging message will still have a chance to be sent on the HSDPA channel, which depends on whether the controlling RNC understands the en...

Embodiment 8

[0119] The serving RNC carries information about whether the serving RNC supports the enhanced paging feature in the paging request message or other signaling on the Iur interface, so that the controlling RNC knows whether the serving RNC supports the enhanced paging capability. RNC does not support enhanced paging.

[0120] Through steps s801-s802, the mobile station can learn whether the serving RNC supports enhanced paging.

[0121] For the controlling RNC, if it is determined that the serving RNC does not support the enhanced paging feature, it will only send a paging message on the SCCPCH; for the mobile station, no matter whether the current cell supports the enhanced paging feature, as long as its serving RNC does not support the enhanced paging feature, Then the paging message is only received on the SCCPCH.

Abstract

The invention discloses a method of determining paging transmission channels, comprising that: a control wireless network controller RNC acquires ability information of a travelling platform; the control RNC determines the channel of transmitting the paging information according to the ability information of the travelling platform and the ability information in the paging domain. An embodiment of the invention also provides a method of triggering a subsystem of a service wireless network to relocate. According to the control RNC in the embodiment of the invention, the travelling platform is determined to monitor the paging information on SCCPCH or HS-PDSCH channel through acquiring the ability whether supporting paging, thereby avoiding paging loss.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for determining a paging transmission channel. Background technique [0002] In the prior art, a mobile station in URA_PCH (UTRAN Registration Area Paging Channel, UTRAN Registration Area Paging Channel) state cannot directly send and receive data. When the network side has data or calls to be sent to the mobile station in the URA_PCH state, it is necessary to send a paging message on the PCH (Paging Channel) on the network side to notify the mobile station. After the mobile station receives the paging message, State transition enters other states for data sending and receiving. For the purpose of power saving, the mobile station in the URA_PCH state performs Discontinuous Reception (DRX), and the mobile station calculates when it should receive its own according to the discontinuous reception period and algorithm negotiated with the network si...
