Abstract:
The disclosure discloses a method and system for transmitting a Physical Random Access Channel (PRACH). The method includes: in a Carrier Aggregation (CA) scenario, a base station transmits, in a Primary Serving Cell (Pcell) or a Secondary Serving Cell (Scell), a random access trigger message to a User Equipment (UE) (401); the UE transmits, in the Scell, a PRACH (402); and the base station transmits, in the Pcell or an Scell, a random access procedure message to the UE (403). With the disclosure, a PRACH can be transmitted in an Scell in the CA scenario.
Abstract:
A method for implementing an IP Multimedia Subsystem (IMS) registration, includes: a Home Subscriber Server (HSS) recording a current registration state of a User Equipment (UE) in response to receiving a Multimedia Authentication Request (MAR) initiated by a Service Call Session Control Function (S-CSCF) selected for the UE when a first Register request is sent by the UE; in response to receiving a second Register request initiated by an Interrogating Call Session Control Function (I-CSCF), the HSS sends the S-CSCF Name to the I-CSCF when the current registration state of the UE is an assigned S-CSCF state. By the scheme, a same S-CSCF is ensured to be used in the two User Authentication Request/User Authentication Answer (UAR/UAA) procedures of the initial IMS registration procedure, and the initial IMS registration of the UE is implemented successfully.
Abstract:
The present invention relates to a fiber optic telecommunication cabinet for use in fiber optic telecommunication networks. The fiber optic telecommunication cabinet comprises a base and a housing. The base has a plurality of ports passing through the base to allow passage telecommunication cables into the fiber optic cabinet. The fiber optic telecommunication cabinet further includes an optical fiber termination block attached to the base. The optical fiber termination block has a plurality of optical modules supported by the mounting frame, wherein the optical modules may be rotated in a plane perpendicular to the longitudinal direction of the fiber optic telecommunication cabinet from a first storage position to a second accessible position.
Abstract:
A query pipeline is created (514) from a query request. The query pipeline includes multiple query operations including multiple query operators. A first query operator and a second query operator perform first and second query operations on a database (526) and on data outside the database (534). A result from the first query operation in the query pipeline is fed to the second query operation in the query pipeline.
Abstract:
The present invention provides a method and apparatus for sequencing ZC sequences of a random access channel. The method comprises: setting α as a logical index of each ZC sequence, and u as a physical index of said each ZC sequence, wherein 1≦u≦N−1, 0≦α≦N−2, and N is the length of said each ZC sequence; establishing a mapping relationship between the logical index and the physical index: u=N/2 is taken as a symmetry axis, α is mapped to u in a manner of longitudinal symmetry, and on the upper side of the symmetry axis, u monotonously decreases or increases, while on the lower side of the symmetry axis, u monotonously increases or decreases. This method ensures that the PRACHs of the UEs using different sequences in a same cell have similar coverage, thus the flexibility of cell planning is increased.
Abstract:
A radio frame and method are provided for sending a sounding reference signal (SRS) in a mobile communication system, which is used to solve the problem of shortage of resources for sending the SRS in the mobile communication system. The method includes a user equipment (UE) sending the SRS to eNB in time-frequency resources corresponding to a guard space in the radio frame, wherein, the guard space is one or more of downlink to uplink guard space, uplink to downlink guard space, reserved subframes, or reserved idle resources. A device is also provided for sending the SRS, applied to the UE in the mobile communication system, wherein the device includes a radio frame construction module and a sounding reference signal transmission module.
Abstract:
