Problems solved by technology

[0022] The disadvantage of the above solution is that: with the existing receiving method, the same data is likely to be sent multiple times at the same time, which greatly wastes resources, and the resource utilization rate is low, which in turn limits the number of access users
[0023] In the 3GPP R99 network, although the cell broadcast service can be realized, the broadcast is limited to carrying message services and cannot carry data services

Embodiment 1

[0051] A fixed value is preset as the C-RNTI, such as 1111 1111 1111 1111, and the fixed value is used as an identifier indicating that all UEs in the cell can receive it.

[0052] figure 1 Shown is the schematic flow chart of embodiment one. In this embodiment, the UE has previously received and stored the C-RNTI assigned by the network side.

[0053] Step 101, UE receives the MAC PDU from the network side, judges the information of the UE-Id type field of the MAC PDU, if it is C-RNTI, then executes step 102, if it is U-RNTI or DSCH-RNTI, executes step 107 .

[0054] Step 102, obtain the identification information of the C-RNTI from the UE-Id field of the received MAC PDU.

[0055] Step 103, judge whether the identification information of the C-RNTI parsed from the MAC PDU is completely consistent with the identification information of the saved C-RNTI, if yes, execute step 107; otherwise, execute step 104.

[0056] Step 104, judging whether the C-RNTI identification info...

Embodiment 2

[0061] The C-RNTI is pre-set to include an intra-group user identification (UEID in Grp domain) domain for distinguishing different users in the multicast group, and a length domain for indicating the length of the UE ID in Grp domain; and, the UE ID in Grp domain Set a piece of fixed identification information, which is used to indicate that all UEs in this group can receive data services.

[0062] For example, the highest bit of the C-RNTI is set as the length field, and its value is set to 0, and all bits except the highest bit are set as the group user identification (UE ID inGrp ) field, see Table 4:

[0063]

[0064] Table 4

[0065] When the highest bit of C-RNTI is 0 and the lower 15 bits of C-RNTI are UE ID in Grp field, a cell has such a group, and there are 32767 users in the group, each bit of UE ID in Grp field is reserved The value is all 1, that is, the fixed identification information when each bit of the UE ID in Grp field is set to be all 1 is used to in...

Embodiment 3

[0076] It is pre-set that the C-RNTI contains the group identification GRP ID field used to distinguish different groups, the group user identification UE ID in Grp field used to distinguish different users in the multicast group, and used to indicate the group identification field GRP ID field and UE The length field of the length of the ID in Grp field; and, setting a fixed identification information for the UE ID in Grp field, which is used to indicate that all UEs in the group can receive data services.

[0077] For example, the highest two bits of C-RNTI are set as the length field, and its value is set to 10, and the two bits behind the length field are set as the group identification (GRP ID field) field for distinguishing different multicast groups, and the All the bits except the length field and the group identification field are set to the group user identification (UE ID in Grp field) field used to distinguish different users in the multicast group, see Table 5:

Abstract

The invention relates to a method for making several users able to receive data service in one channel. First setting a C-RNTI mark for instructing that several UE can receive data service in one channel for the C-RNTI; when each UE receives MAC PDU from network, analyzing the information of UE-Id type area as C-RNTI and judging the analyzed C-RNTI mark is the preset one; when it can receive, receiving the data service in MAC PDU. Therefore, it can realize multi-broadcast channel in R99 network, and several users can receive data service in one channel, without adding any new parameter but only setting the meaning of C-RNT1, with better compatibility and easy operation.

Description

technical field [0001] The invention relates to the third generation mobile communication system, in particular to a method for enabling multiple users to receive data services in the same channel in the 3GPP R99 network. Background technique [0002] In the existing 3GPP R99 network, various services are provided for users, especially various data services can be provided for users, which meets various demands of users. For example, using a mobile phone to watch streaming TV is one of the data services provided by the existing 3GPP R99 network. [0003] The above-mentioned data service is usually implemented through a dedicated channel. The implementation process of the data service will be described in detail below by using a mobile phone to watch a streaming TV service as an example. [0004] As we all know, in the third generation communication system, the user equipment (UE) usually has two modes, one is the idle (IDLE) mode, which is often referred to as the standby s...
