The MME initiates the Initial Context Setup procedure by sending INITIAL CONTEXT SETUP REQUEST to the eNB. This message may include general UE Context (e.g. security context, roaming restrictions, UE capability information, UE S1 signalling connection ID, etc.), and may be piggy-backed with the corresponding NAS messages.
The INITIAL UE MESSAGE contains a NAS message (e.g. Service Request), the UE signalling reference ID and other S1 addressing information.

1.在RRC idle狀態的UE，要與核心網路傳輸之前必須要先進行Random Access Procedure以取得空中資源。所以UE這時向EnodeB進行Random Access Msg 1的動作，要知道Random Access，請點此。
2.EnodeB 收到Random Access之後會回應Random Access Response，讓UE知道EnodeB有收到此訊息，並告知UE 參數何時可以上傳
3.UE收到Random Access Response之後，即可開始進行RRC Connection Request
4.EnodeB收到RRC Connection Request後即會回覆UE的RRC Connection Setup，UE收到RRC Connection Setup之後，表示收到SRB1 。前面四個步驟都屬於Random Access的範疇。
5.UE使用SRB1向eNodeB發送RRC Connection Setup Complete，告知EnodeB已經做好 SRB1的配置，並且夾帶Attach Request在 RRC訊息內的 "dedicatedInfoNASList "進行傳送。
6.EnodeB 收到後會將 "dedicatedInfoNASList "的訊息直接往後端MME傳送，而不做處理。
7.MME收到Attach Request之後，通常會向UE進行Authentication的步驟，確認UE是網路合法的用戶。
8.確認UE的身分後，MME會發送Attach Accept，並主動建立Default EPS Bearer，讓UE有封包傳送能力。並告知EnodeB Initial Context Setup要做些什麼，例如說要不要加密等等行為
9.EnodeB收到 Attach Accept之後，這時EnodeB會先確認UE裝置目前的能力為何，故使用UE Capability Enquiry，例如說UE可不可以使用WCDMA、EVDO、GSM、1x的訊號等等能力，因為SIM卡可以插不同的手機!
10.UE收到後會回覆UE Capability Information來讓EnodeB知道自己UE的裝置能力
11.EnodeB收到後也會轉送給MME讓MME知道UE的能力狀況，並在MME資料上做更新
12.若EnodeB在第八步驟收到EnodeB Initial Context Setup是需要做加密的，這時就會使用Security Mode Command與UE加密初始化的動作
13.UE確認加密訊息沒問題之後 會回覆給EnodeB Security Mode Complete 在此之後的訊息就都是加密，必須要密鑰才可以解的開。
14.確認加密之後EnodeB將第八部的Attach Accept及Activate Default EPS Bearer。這時UE會重新配置RRC，包括重新配置SRB1，及設置SRB2及DRB等
15.UE設置完之後告知EnodeB已經設定完RRC的資源，
16.EnodeB告知MME initila Context Setup Response，表示MME所要做的事情已經做完。
17.UE在配置完之後，回傳Attach Complete，Active EPS Bearer context Accetpt給EnodeB，實際上是包在"dedicatedInfoNASList "裡面要給MME的回覆訊息。
18.EnodeB轉送UE"dedicatedInfoNASList "中的訊息給MME，至此UE就可以開始使用Default EPS bearer進行資料的傳送。

UE Inactivity is detected, etc…
All radio resources are released
Release RLC/PDCP entity and MAC config for all RBs

43. Handover Preparation (X2)
0 The UE context within the source eNB contains information regarding roaming restrictions which were provided either at connection establishment or at the last TA update.
1 The source eNB configures the UE measurement procedures according to the area restriction information. Measurements provided by the source eNB may assist the function controlling the UE's connection mobility.
2 The UE is triggered to send MEASUREMENT REPORT by the rules set by i.e. system information, specification etc.
3 The source eNB makes decision based on MEASUREMENT REPORT and RRM information to hand off the UE.
4 The source eNB issues a HANDOVER REQUEST message to the target eNB passing necessary information to prepare the HO at the target side (UE X2 signalling context reference at source eNB, UE S1 EPC signalling context reference, target cell ID, KeNB*, RRC context including the C-RNTI of the UE in the source eNB, AS-configuration, E-RAB context and physical layer ID of the source cell + short MAC-I for possible RLF recovery). UE X2 / UE S1 signalling references enable the target eNB to address the source eNB and the EPC. The E-RAB context includes necessary RNL and TNL addressing information, and QoS profiles of the E-RABs.
5 Admission Control may be performed by the target eNB dependent on the received E-RAB QoS information to increase the likelihood of a successful HO, if the resources can be granted by target eNB. The target eNB configures the required resources according to the received E-RAB QoS information and reserves a C-RNTI and optionally a RACH preamble. The AS-configuration to be used in the target cell can either be specified independently (i.e. an "establishment") or as a delta compared to the AS-configuration used in the source cell (i.e. a "reconfiguration").
6 The target eNB prepares HO with L1/L2 and sends the HANDOVER REQUEST ACKNOWLEDGE to the source eNB. The HANDOVER REQUEST ACKNOWLEDGE message includes a transparent container to be sent to the UE as an RRC message to perform the handover. The container includes a new C-RNTI, target eNB security algorithm identifiers for the selected security algorithms, may include a dedicated RACH preamble, and possibly some other parameters i.e. access parameters, SIBs, etc. The HANDOVER REQUEST ACKNOWLEDGE message may also include RNL/TNL information for the forwarding tunnels, if necessary.
NOTE: As soon as the source eNB receives the HANDOVER REQUEST ACKNOWLEDGE, or as soon as the transmission of the handover command is initiated in the downlink, data forwarding may be initiated.
Steps 7 to 16 provide means to avoid data loss during HO and are further detailed in and
7 The target eNB generates the RRC message to perform the handover, i.e RRCConnectionReconfiguration message including the mobilityControlInformation, to be sent by the source eNB towards the UE. The source eNB performs the necessary integrity protection and ciphering of the message. The UE receives the RRCConnectionReconfiguration message with necessary parameters (i.e. new C-RNTI, target eNB security algorithm identifiers, and optionally dedicated RACH preamble, target eNB SIBs, etc.) and is commanded by the source eNB to perform the HO. The UE does not need to delay the handover execution for delivering the HARQ/ARQ responses to source eNB.
8 The source eNB sends the SN STATUS TRANSFER message to the target eNB to convey the uplink PDCP SN receiver status and the downlink PDCP SN transmitter status of E-RABs for which PDCP status preservation applies (i.e. for RLC AM). The uplink PDCP SN receiver status includes at least the PDCP SN of the first missing UL SDU and may include a bit map of the receive status of the out of sequence UL SDUs that the UE needs to retransmit in the target cell, if there are any such SDUs. The downlink PDCP SN transmitter status indicates the next PDCP SN that the target eNB shall assign to new SDUs, not having a PDCP SN yet. The source eNB may omit sending this message if none of the E-RABs of the UE shall be treated with PDCP status preservation.
9 After receiving the RRCConnectionReconfiguration message including the mobilityControlInformation , UE performs synchronisation to target eNB and accesses the target cell via RACH, following a contention-free procedure if a dedicated RACH preamble was indicated in the mobilityControlInformation, or following a contention-based procedure if no dedicated preamble was indicated. UE derives target eNB specific keys and configures the selected security algorithms to be used in the target cell.
10 The target eNB responds with UL allocation and timing advance.
11 When the UE has successfully accessed the target cell, the UE sends the RRCConnectionReconfigurationComplete message (C-RNTI) to confirm the handover, along with an uplink Buffer Status Report, whenever possible, to the target eNB to indicate that the handover procedure is completed for the UE. The target eNB verifies the C-RNTI sent in the RRCConnectionReconfigurationComplete message. The target eNB can now begin sending data to the UE.
12 The target eNB sends a PATH SWITCH REQUEST message to MME to inform that the UE has changed cell.
13 The MME sends a MODIFY BEARER REQUEST message to the Serving Gateway.
14 The Serving Gateway switches the downlink data path to the target side. The Serving gateway sends one or more "end marker" packets on the old path to the source eNB and then can release any U-plane/TNL resources towards the source eNB.
15 The Serving Gateway sends a MODIFY BEARER RESPONSE message to MME.
16 The MME confirms the PATH SWITCH REQUEST message with the PATH SWITCH REQUEST ACKNOWLEDGE message.
17 By sending the UE CONTEXT RELEASE message, the target eNB informs success of HO to source eNB and triggers the release of resources by the source eNB. The target eNB sends this message after the PATH SWITCH REQUEST ACKNOWLEDGE message is received from the MME.
18 Upon reception of the UE CONTEXT RELEASE message, the source eNB can release radio and C-plane related resources associated to the UE context. Any ongoing data forwarding may continue. TS
