Description

Support the method and apparatus that UE carrying recovers

Technical field

The present invention relates to wireless communication technology, particularly support the method and apparatus that UE carrying recovers.

Background technology

Present mobile communication more and more trends towards as user provides the multimedia service of high rate data transmission, as shown in Figure 1, is the system architecture diagram of System Architecture Evolution (SAE).Wherein:

Subscriber equipment (UE) 101 is used to the terminal equipment receiving data.

Evolved universal terrestrial radio access network (E-UTRAN) 102 is Radio Access Networks, comprising the macro base station (eNodeB/NodeB) providing access of radio network interface for UE.

Mobile management entity (MME) 103 is in charge of the mobile context of UE, session context and security information.

Gateway (SGW) 104 mainly provides the function of user plane, MME103 and SGW104 may be in Same Physical entity.

Grouped data network gateway (PGW) 105 is responsible for the function such as charging, Lawful Interception, also can be in Same Physical entity with SGW104.

"Policy and Charging Rules Function entity (PCRF) 106 provides service quality (QoS) strategy and charging criterion.

Universal grouping wireless business supporting node (SGSN) 108 is for the transmission of data provides the apparatus for network node of route in universal mobile telecommunications system (UMTS).

Home subscriber server (HSS) 109 is local ownership subsystems of UE, and responsible protection comprises the user profile such as packet data content of the current location of subscriber equipment, the address of service node, user security information, subscriber equipment.

3GPP proposes at version 12 (Rel-12) demand that small-cell (smallcell) strengthens, the target scene that small-cell strengthens includes the scene and the scene that do not have macrocell to cover that macrocell covers, indoor and outdoors, the enhancing of ideal and imperfect backhaul.

When there being macrocell to cover, propose the technology can applying carrier aggregation between different base station.Macrocell and small-cell can be operated in different frequency ranges.The framework of technology of the carrier aggregation between application different base station has two kinds: the framework (RANSplit) that user plane data separates based on wireless access network (RAN) and the framework (CNSplit) separated based on core net (CN).The framework divided out based on CN refers to: for the carrying be based upon on picocell (pico), data directly send to Pico community by the SGW of core net, and user plane data is not forwarded by macrocell (macro).

In the framework of small-cell, UE can simultaneously two base station transceiver data, and this is called dual link (dual-connectivity).Wherein, a base stations being in charge is only had to send wireless heterogeneous networks (RRC) message to UE, and be responsible for core net control plane entity MME mutual, this base station is called dominant base (MeNB), and another base station is called prothetic group station (SeNB).UE is the main plot (Pcell) of UE in dominant base You Yige community, sends RRC information to UE, Shi Fu community, other communities (Scell) by this main plot.In the Scell at prothetic group station, You Yige community is prothetic group station owner community (pScell).PScell there is upstream physical layer control channel, other Scell do not have.The cell set of dominant base is called MCG, and the cell set at prothetic group station is called SCG.UE holds the configuration of auxiliary cell set to be configured by prothetic group station, and prothetic group station sends to dominant base by RRC container by the configuration of UE, sends to UE by dominant base.Dominant base does not resolve RRC container.Or resolve but the configuration do not changed in RRC receptacle.

As (SGWerrororeNBerror) after SGW or eNB makes a mistake or after restarting, bearer context will be lost.When SGW or eNB receives GPRS Tunnel Protocol (GTP-U) bag of user level, but SGW or eNB not this GTP-U wrap bearer context information time, SGW or eNB will lose this bag, and send the instruction of GTP mistake to end of giving out a contract for a project.

When MeNB receives the GTP mistake instruction from SGW from S1-U passage (S1-UTunnel, S1 interface user plane passage), MeNB need trigger RAB (E-RAB) dispose procedure of evolution.

When SeNB receives the GTP mistake instruction from SGW from S1-U passage, SeNB need delete local S1-U passage.

When SGW receives the GTP mistake instruction from eNB from S1-U passage, SGW will delete the Tunnel End Point Identifier (TEID) of the S1-U passage of this eNB all, and SGW also will send downlink data notification message to MME.After MME receives this message, if UE is connected state, the S1 that MME discharges UE connects, then performs the service request procedure of network-triggered.

Under the existing dual link framework separated in core net, also there is following problem after receiving the instruction of GTP mistake in SGW, MeNB and SeNB:

It is inactive that all UE may be carried the carrying be based upon on SeNB or on MeNB by problem 1:MeNB.When mistake appears in SGW, when SeNB sends GTP-U bag to SGW, if SGW has lost the context of UE carrying on this SeNB, SGW will send the instruction of GTP mistake to SeNB.After SeNB receives the instruction of GTP mistake, local S1-U passage will be discharged, MeNB may can not receive the GTP mistake instruction that SGW sends, then MeNB cannot know the release that the reason due to SGW causes, and the UE carrying on SeNB also may can be established on other SeNB or transfer to MeNB by MeNB.But this UE is carried on SGW does not have context, should discharge.

Problem 2: when SeNB makes a mistake, if SGW sends GTP-U bag to SeNB, SeNB will return the instruction of GTP mistake to SGW.Because SGW does not distinguish SeNB or MeNB, SGW by the channel information of all carryings of release this UE all, and indicates MME to discharge the connection of this UE.Namely the mistake of SeNB is all released causing all carryings on MeNB, thus causes the disconnecting of UE.

Step 402: when SGW determine SeNB make a mistake or UE carrying make a mistake after, SGW can perform following one or more operation:

1) SGW can not discharge S1-U passage on MeNB.

2) SGW can not discharge S1-U passage on SeNB.

3) SGW can not send downlink data notification to MME.

4) SGW can send UE to MME and carry the instruction made a mistake, and described instruction can be the UE bearing identification that the UE that makes a mistake carries the IP address of the eNB at place, identification information, eNB type, UE bearer types or makes a mistake.Now, the IP address of eNB or identification information are IP address or the identification information of SeNB, and eNB type is SeNB.

5) SGW can rebuild, shift or discharge to MME instruction the UE carrying on SeNB.

6) SGW can send to MME the S1-U passage corresponding UE bearing identification and/or reason that receive the instruction of GTP mistake.

7) SGW can rebuild to MME instruction, shift or discharge the S1-U passage corresponding UE carrying receiving the instruction of GTP mistake.

According to following information, SGW can determine that SeNB makes a mistake: when SGW receives the GTP mistake instruction of UE carrying, the eNB type carrying place according to UE is that SeNB determines that SeNB makes a mistake, or is that SCG carrying determines that SeNB makes a mistake according to UE bearer types.

According to following information, SGW can determine that the UE made a mistake carries: the UE that the S1-U passage of the GTP mistake instruction received is corresponding carries.

Before execution aforesaid operations, SGW can send an empty GTP-U bag (such as: Dummy wraps) to the MeNB of UE of the UE carrying made a mistake, and confirms whether MeNB breaks down or confirm whether MeNB has lost the context of UE carrying according to whether receiving the GTP mistake instruction that MeNB sends.If MeNB does not break down or do not lose the context of UE carrying, then perform above operation.
