Problems solved by technology

[0005] From the existing LTE system message notification process, it can be seen that from receiving the PI indication from the base station to finally reading the changed system message, the UE needs to demodulate different channels three times and read the system message once. Similarly, the base station also needs to It is necessary to transmit different information on different channels, which not only causes waste of resources, but also increases the delay of the UE to obtain the system information after the change, and in severe cases, it will also affect the normal progress of the subsequent process

Embodiment 1

[0029] In this embodiment, the system message information is a changed system message, and the base station directly places the changed system message on the PCH for transmission, and the special identifier is a reserved value indicated by PI, that is, a special PI indicator. Such as figure 1 As shown, the method for implementing system message update in this embodiment includes the following steps:

[0030] Step 11: If the system information changes, the base station determines a special PI indication to replace the common PI indication to broadcast on the downlink shared physical control channel when scheduling the PCH through the downlink shared physical control channel, and the transmission position of the system information is placed In the resource indication field on the downlink shared physical control channel corresponding to the determined PI indication; and, the base station directly places the changed system message on the PCH corresponding to the PI indication for...

Embodiment 2

[0037] In this embodiment, the system message information is the time-frequency resource position for transmitting the changed system message, and the base station transmits the time-frequency resource position for transmitting the changed system message on the PCH. Such as figure 2 As shown, the method for implementing system message update in this embodiment includes the following steps:

[0038] Step 21: If the system information changes, the base station determines a special identifier to broadcast on the downlink shared physical control channel when scheduling the PCH through the downlink shared physical control channel. At the same time, the resource indicator field on the downlink shared physical control channel Indicates the transmission position of the time-frequency resource position on the PCH; and, the base station places the time-frequency resource position for transmitting the changed system message on the designated position of the PCH for transmission.

Embodiment 3

[0042] In this embodiment, the system message information is a changed system message, and the base station directly places the changed system message on the PCH for transmission, and the special identifier is a reserved value indicated by PI, that is, a special PI indicator, and this In the embodiment, the base station sets the corresponding relationship between different special PI indications and different system message versions in advance, and notifies the UE of the set corresponding relationship in advance. Such as image 3 As shown, the method for implementing system message update in this embodiment includes the following steps:

[0043] Step 31: If the system message changes, when the base station schedules the PCH through the downlink shared physical control channel, determine a special PI indicator to replace the common PI indicator and send it in broadcast mode on the downlink shared physical control channel, and the transmission position of the system message is p...

Abstract

The invention discloses a method for updating system messages, more particularly, the method is that when the system messages change, a base station determines a special mark which indicates the change of the system messages; the determined special mark is sent on a downlink shared physical control channel and the system message information is sent on a paging channel; a user equipment obtains the system message information from the paging channel according to the demodulated special mark. The invention also discloses the user equipment and the base station at the same time and by adopting the method and the equipment of the invention, the waste of resources and the time of transferring and updating the system messages are reduced.

Description

technical field [0001] The invention relates to a message update technology in a mobile communication system, in particular to a system message update method and a device for realizing it. Background technique [0002] In the third generation (3G) mobile communication system, according to the existing standards of the 3rd Generation Partnership Project (3GPP), if the system message changes, the base station will notify the user by sending a corresponding indication on the paging channel (PCH) Equipment (UE). Moreover, according to the 3GPP standard, only the system message change indication is sent on the PCH, while the system message is sent on the broadcast channel (BCH), and both the BCH and the PCH are mapped to dedicated physical resources. The specific notification process is as follows: when the system information changes, the base station will carry the broadcast control channel modification information (BCCH Modification Information) on the PCH to indicate the chan...
