Problems solved by technology

Therefore, in LTE, since the MCCH cannot be updated within one MCCH modification period, the PF information and the MBMS service information to be counted cannot be carried in the MCCH and sent at the same time, otherwise it will cause the The mechanism of receiving services on the UE side cannot be implemented correctly, so that the UE cannot obtain statistical information correctly

[0086] The first embodiment: In the present invention, aiming at the reason why the information carried in the MCCH cannot be modified within the MCCH modification period in LTE, it is particularly proposed that the slowly changing statistical MBMS service information is carried in the MCCH, or for the MCCH The MBMS services that need statistical feedback are identified, for example, an indicator bit is introduced for each MBMS service in the MCCH to indicate whether the MBMS service needs statistical feedback. Then the rapidly changing PF information itself is not carried in the MCCH, but the radio frame and / or subframe information describing the exact position of the PF information is carried in the SIB13 and sent to the UE. The specific configuration of the PF information is introduced below.

[0087] For LTE, it is assumed that three parameters are added in SIB13, which are used to describe radio frame and / or subframe information of PF information. These three parameters ...

[0097]The second embodiment: the same as the parameter configuration in the first embodiment, except that the parameters in the first embodiment are placed in the MCCH, that is, the radio frame period of the PF information or the number of occurrences of the PF information is configured in the MCCH, and the PF The radio frame offset of the information, and the subframe information of the PF information. Among them, the configuration and use of parameters are the same as those in SIB13 in the first embodiment, and some implicit methods and precautions in parameter configuration, such as the configuration of the radio frame offset parameter of PF information, and the subframe and Notes on MCCH configuration, etc. Since the non-MBMS-capable UE will not receive the MCCH, using the MCCH to carry the radio frame and / or subframe information for sending PF information can better avoid the impact on the non-MBMS-capable UE.

[0098] In addition, configuring the radio frame and / or subf...

[0099] The third embodiment: two parameters are used to configure the PF information location information, one of which is the interval between the MCCH that sends the counted MBMS service information and the first PF information occurrence location, how many radio frames or subframes can be used for the interval The period of the PF information is described as the interval between PF information, which can be described by how many radio frames or subframe durations are used for the interval. For details, please refer to figure 2 . in,

[0100] The configuration of the interval needs to consider the processing delay after the UE receives the MCCH containing the statistical MBMS service information. Generally, the UE processing needs 2-3ms, that is, the duration of 2-3 subframes, so the interval needs to be greater than the processing delay;

[0101] The period value range of PF information is a set of rf16, rf32, rf64, rf128, rf256 and rf512, and rfn represents the duration...

Abstract

The invention discloses a method and a system for transmitting a multimedia broadcast multicast service (MBMS) access probability factor. The method comprises that: a network side bears access probability factor (PF) information at a position corresponding to PF information position information for identifying the bearing position of the PF information for transmission, wherein the PF information is not born in a multicast control channel (MCCH). By the method provided by the invention, the PF information is not born in the MCCH for transmission, so the influence of updating incapability of the MCCH in an MCCH modification period on the fast variability of the PF information in long term evolution (LTE) is avoided, and the accurate implementation of a mechanism for counting the receiving conditions of a certain MBMS on a user side by the network side is ensured.
