Problems solved by technology

In other words, a BTS decision to enable a paging extension becomes less likely to result in successful paging of the desired device - as the time from the decision to use the paging extension until the corresponding planned paging extension increases
[0009] Fourth, where there are pages that can be sent to support paging extensions using an EC-CCCH block in the last TDMA EC-CCCH resources may be wasted

Embodiment 1

[0068] Embodiment 1: Downlink coverage class of paging message subject to paging extension < downlink coverage class associated with ongoing blind transmission

[0069] Details of an example of Embodiment 1 (hereinafter also referred to as "sub-embodiment 1") will be discussed below. In sub-embodiment 1, no gap is normally required. It should be understood that Sub-Embodiment 1 is an example of Embodiment 1 and is described for purposes of discussion and not limitation.

[0070] When the downlink coverage class of the paging message sent using the paging extension < the downlink coverage class of the ongoing blind transmission, there are cases where the paging extension does not require a gap (i.e., before it reads to determine the Its coverage class has a built-in gap between the last ongoing blind transmission with paging extension enabled and where it knows the paging extension occurred, so no gaps are needed).

[0071] Figure 4 is an example CC1 MSb that reads TDMA fra...

Embodiment 2

[0087] Embodiment 2: Downlink coverage class of paging message subject to paging extension = downlink coverage class associated with ongoing blind transmission

[0088] A minimum gap of X (X = 0, 1, 2, ...) EC-PCH blocks is required because the MS has to read the ongoing All copies of the blind transfer. This minimum gap is required so that the MS can know if paging extension is enabled, and thus only prepare for paging extension if it is already enabled for its downlink coverage class.

[0089] For example, in the case where CC4 MSa blind transmission is shown and CC4 MSb is used for paging extension Figure 6 , after CC4 MSb reads the last blind transmission at TDMA frame 34 on MF N+3 according to its nominal paging group, it determines that the message sent therein is associated with another CC4 MSa and targets CC4 Enable paging extension. CC4 MSb requires a gap of 8 EC-PCH blocks to prepare for paging extension at TDMA frame 19 on MF N+4.

[0090] At 601, CC4 MSa trans...

Embodiment 3

[0094] Example 3: Suggested optional improvements when considering implementation

[0095] Considering the definition of paging group extensions and static relations between paging groups to make it easier for BTSs and MSs, the following optional improvements are suggested:

[0096] A) When a blind transmission is in progress for an MS with a higher downlink coverage class and a CC1 MS requires paging extension, there is a possibility to read a different TDMA frame associated with its nominal paging group A number of CC1 MSs will require paging group expansion.

[0097] For example, in Figure 4 In , seven CC1 mobile stations with their nominal paging groups starting at TDMA frames 19, 21, 23, 25, 27, 29, 31 on MF N can use the same set of TDMA frames (i.e., MF N FN 35 and 36) for paging extension.

[0098] But EC-PCH can only send paging messages indicating up to 2 TMSIs using paging extension. To avoid having these CC1 MSs use the same paging group extension instance, a ...

Abstract

Embodiments of the present invention generally relates to the processing of paging extensions in a wireless communication network. The terminal device in the wireless communication network receives a message including an indication of the paging extension for the terminal device from the base station in the wireless communication network. The terminal device is associated with the first coverage category. Based on the message, the terminal device determines a second coverage category from the base station to the downlink transmission of the other terminal device. The terminal device then determines the target paging group for paging expansion based on the first coverage category and the second coverage category.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the communication field, and more particularly relate to a method and device for processing paging extension. Background technique [0002] Traditionally, devices that have enabled Extended Coverage (EC) - Global System for Mobile Communications (GSM) - Internet of Things (IoT) operations in which Extended Discontinuous Reception (eDRX) is used wake up to read data based on their negotiated eDRX cycle. Take its nominal paging group. As described in the 3GPP specification, if the device does not receive a matching paging message with the EC paging extension field included in it, it proceeds as follows: [0003] If the EC Paging Extensions field indicates that paging extensions are enabled for its downlink coverage class, it sets its eDRX cycle to the lowest eDRX cycle and tries to use the last The first instance of its nominal paging group (computed using the lowest eDRX cycle) that occurs afte...
