Problems solved by technology

The introduction of interrupts will interrupt the current process of the UE, and bring a series of complex operations and overheads such as protecting the site and restoring the site.
[0006] It can be seen that according to the current MBMS service session retransmission method in the 3GPP protocol, a series of unnecessary complicated operations and overheads (including power consumption and UE processing resource consumption) will be brought to most users

Embodiment Construction

[0018] First, the present invention adopts such as figure 1 In the MICH frame structure shown, the MICH frame structure uses 1 to 12 vacant bits of the original MICH frame structure on the MICH channel to establish a session retransmission flag. The session retransmission flag bit is any number of bits among at most 12 bits and the permutation and combination of these bits. The coded content on the session retransmission flag bits (any one of 1 to 12 bits is acceptable) can be "all 0", "all 1" or other forms of 01..., 10... and so on.

[0019] The following will take 12 bits as an example to illustrate.

[0020] As shown in Table 1, a flag bit of "all zeros" indicates the first transmission or special retransmission of the MBMS session, while a flag bit of "all ones" indicates the general retransmission of the MBMS session. (Certainly, it is also possible to use flag bits as "all ones" to indicate that the MBMS session is transmitted for the first time or special retransmiss...

Abstract

This invention relates to a method for improving re-trasmission multimedia broadcast, multicast service sessions and its MICH frame structure including: the UE monitors all bp information on the MICH channel, once it monitors that the NI identification corresponding to the belonged MBMS service set is called, it determines if the current MBMS session is a normal re-transmission, a first transmission or a special one based on the content of the flag bit set up on the vacant bits of the MICH frame, it will not let users having received all session data of the subscribed MBMS service before the normal re-transmission receive the MBMS data, the rest will be processed in terms of the normal rule.

Description

technical field [0001] The present invention relates to the third generation mobile communication (3 rd G) A method for improving MBMS (Multimedia Broadcast / Multicast Service, Multimedia Broadcast / Multicast Service) service session retransmission and MICH (MBMS Indicator Channel, MBMS Announcement / Paging Indicator Channel) frame structure in implementing the method. Background technique [0002] According to the current 3GPP (3rd Generation Partnership Project, third-generation mobile communication cooperation project) agreement, several MBMS services are classified into one MBMS service group, and each MBMS service group has a corresponding identification NI (notification indication) on the MICH channel. ). Each user terminal (UE) monitors the MICH channel. Once the corresponding NI identifier on the MICH channel is paged, the UE will read and compare the NI at the beginning of each adjustment period of the MCCH channel (MBMS control channel). For the MBMS service identif...
