Embodiment 1

[0041] see Figure 6 as shown, Figure 6 It is a schematic diagram of the access process of the present invention. During initial access, the following steps are involved:

[0042] Step 1. The UE initiates initial access. During the initial access process, it exchanges UE bandwidth capability information with the MAC of the eNodeB node, and carries the random access identifier, cell identifier, and downlink signal through the random access channel (RACH). In addition to the specific information, it also carries the UE bandwidth capability information and reports it to the MAC of the eNodeB node;

[0043] Step 2. The MAC of the eNodeB node reports the UE bandwidth capability information to the RRM. The RRM schedules and allocates bandwidth resources that do not exceed the bandwidth capability according to the received UE bandwidth capability information, and sends the UE through the downlink L1 / L2 control channel to allow the UE to access;

[0044] Step 3: The UE initiates ...

Embodiment 2

[0047] To improve the reliability of the UE's bandwidth capability information exchanged with the eNodeB, a three-way handshake can be used. see Figure 7 as shown, Figure 7 It is a schematic diagram of the access process of the present invention. During initial access, the following steps are involved:

[0048] Step 1. The UE initiates initial access. During the initial access process, it exchanges UE bandwidth capability information with the MAC of the eNodeB node, and carries random access identifiers, cell identifiers, and downlink signal-to-interference ratios through the random access channel (RACH). In addition to the information, it also carries the UE bandwidth capability information and reports it to the MAC of the eNodeB node;

[0049] Step 2, the MAC of the eNodeB node sends a request to confirm the UE bandwidth capability message to the UE;

[0050] Step 3, the UE sends a message confirming the bandwidth capability of the UE to the MAC of the eNodeB node;

Abstract

The present invention is an access method of user equipments (UE) in mobile communication system, a UE interacts the bandwidth capability of the UE with the device in network side. The device in network side allocates resource that is matched with bandwidth capability of the UE to the UE according to the bandwidth capability of the UE, and permits the UE to access network. The present invention adapts to the access of UEs having different bandwidth capability in long term evolution system.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method for user equipment (UE) access in a long term evolution (LTE, longterm evolution) mobile communication system. Background of the invention [0002] Since the 3GPP released the first commercial version of the Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System) network Realse99, members of the 3GPP organization have continued to improve the network in order to obtain more network features and better network performance. figure 1 The evolution process of the UMTS network is shown. Among them, in the medium-term evolution process, the existing network will be optimized as much as possible without major changes, and HSDPA (High Speed ​​Downlink Packet Access) and HSUPA (High Speed ​​Uplink Packet Access) will be introduced to make WCDMA wireless access Performance has been significantly improved. The long-term e...
